As shown in FIG. 2B, the indirect vaporization element 11 includes a dry cell 21 having a plurality of first flow paths 21b partitioned by a partition 21a, and a plurality of second flow paths 22b partitioned by a partition 22a. A wet cell 22 and a dry cell 21 and a partition wall 23 partitioning the wet cell 22.

[0058] The dry cell 21 and the wet cell 22 are stacked with the partition wall 23 in between in a direction in which the first flow path 21b and the second flow path 22b are orthogonal to each other.

[0059] As shown in FIG. 2C, the partition wall 23 is a moisture-proof film 2 formed of a polyethylene film or the like.

3a and a wet layer 23b formed of pulp or the like, the moisture-proof film 23a faces the dry cell 21, and the wet layer 23b faces the wet cell 22.

Further, as shown in FIG. 2B, the partition wall 23 is formed with a vent hole 23c that connects a part of the first flow path 21b and the second flow path 22b. Further, as shown in FIG. 2A, a closed portion 24 is formed at the outlet of the first flow path 21b in which the vent hole 23c is formed, and is configured so that air does not pass through.

Thereby, in the indirect vaporization element 11, the working air channel 11a The inlet of the first channel 21b in which 3c is formed communicates with the outlet of the second channel 22b through the first channel 21b, the vent hole 23c, and the second channel 22b. Further, the product air flow path l ib communicates from the inlet of the first flow path 21b where the vent hole 23c is not formed to the outlet of the first flow path 21b through the first flow path 21b.

[0062] The outline of the cooling principle by the indirect vaporization element 11 will be described with reference to FIG. 2C. Here, 力 King Air WA and Product Air PA are flowing in the direction perpendicular to each other. In Fig. 2C, the flow direction of ヮ King Air WA and Product Air PA is shown in parallel!

[0063] The wetting layer 23b facing the working air flow path 11a is supplied with water by the water supply / drainage device 12 shown in FIG. Thus, moisture is vaporized by the temperature difference between the working air WA passing through the working air flow path 11a and the wet layer 23b, and the working air WA is cooled.

[0064] When the working air WA is cooled, the product air PA passing through the product air channel l ib partitioned by the working air channel 11a and the partition wall 23 is cooled by receiving cold heat through the partition wall 23.

[0065] Here, since the moisture-proof film 23a constituting the partition wall 23 does not pass moisture, the product air PA does not change its absolute humidity even when it passes through the product air flow path ib. In addition, when the working air WA passes through the working air flow path 11a, the humidity becomes high.

[0066] As an example, if the input temperature of product air PA and working air WA is 30 ° C, the absolute humidity is 10gZkg (DA: dry air), and the relative humidity is about 40% RH, the outlet temperature of product air PA is It drops to 20 ° C. The relative humidity rises to about 70% RH due to a decrease in temperature, but the absolute humidity is lOgZkg (DA) and does not change.

[0067] In addition, the exit temperature of the working air WA will drop to 23 ° C. However, absolute humidity is 16gZkg

It goes up with (DA).

[0068] <Cooling principle of indirect vaporization element>

The cooling principle of the indirect vaporization element 11 can be expressed as follows using the temperature Td of product air PA, absolute humidity Xd, air volume Gd, temperature Tw of working air WA, absolute humidity Xw, air volume Gw, and other parameters.

[0073] (3) Relationship between working air WA flow rate and product air PA outlet temperature From the above equation, the relationship between the flow rate of the working air WA in the indirect vaporization element 11 and the outlet temperature of the product air PA is obtained and shown in the graph of FIG.

[0074] Figure 3 is a graph showing the relationship between the flow rate of the working air WA and the outlet temperature of the product air PA. The conditions of the working air WA and the product air PA input to the indirect vaporization element 11 are the absolute humidity 5.26gZkg (DA: dry air), inlet temperature fixed at 30 ° C, product flow rate of PA fixed at 50m ³ Zhr.

[0075] From Fig. 3, it can be seen that the higher the working air WA flow rate, the lower the outlet temperature of the product air PA. Note that the air cooled by the indirect vaporization element 11 has a temperature distribution, but the temperature data in each example is described at the lowest temperature.

[0076] (4) Relationship between product air PA flow rate and product air PA outlet temperature

From the above formula, the relationship between the flow rate of product air PA in the indirect vaporization element 11 and the outlet temperature of product air PA is obtained and shown in the graph of FIG.

[0077] Fig. 4 is a graph showing the relationship between the flow rate of the product air PA and the outlet temperature of the product air PA. The conditions of the working air WA and the product air PA input to the indirect vaporization element 11 are the absolute humidity 5.26g / kg (DA), inlet temperature fixed at 30 ° C, working air WA flow rate fixed at 50m ³ Zhr.

[0078] From FIG. 4, the product air PA outlet temperature decreases as the flow rate of the product air PA decreases.

[0079] (5) Relationship between inlet temperature of working air WA and product air PA and outlet temperature of product air PA

From the above formula, the relationship between the working air WA and product air PA inlet temperatures and the product air PA outlet temperature in the indirect vaporization element 11 is obtained and shown in the graph of FIG.

The conditions of the working air WA and the product air PA input to the indirect vaporization element 11 are absolute. Humidity 5.26gZkg (DA), flow rate fixed at 50m ³ Zhr.

[0081] From FIG. 5, the higher the inlet temperature of working air WA and product air PA, the higher the product. It can be seen that the outlet temperature of TOA PA is rising.

[0082] (6) Relationship between working air WA and product air PA inlet temperature and water consumption From the above formula, relationship between working air WA and product air PA inlet temperature and water consumption in indirect vaporization element 11 Is shown in the graph of Fig. 6.

The conditions of working air WA and product air PA input to indirect vaporization element 11 are absolute humidity 5 26gZkg (DA), flow rate fixed at 50m ³ Zhr.

[0084] From FIG. 6, it can be seen that the higher the inlet temperature of the working air WA and the product air PA, the greater the consumption of water used for cooling.

[0085] From this, it can be seen from FIGS. 5 and 6 that if the inlet temperature of the working air WA and the product air PA is lowered, the outlet temperature of the product air PA is lowered and the water consumption is reduced.

[0086] (7) Relationship between working air WA and product air PA inlet humidity and product air PA outlet temperature

From the above formula, the relationship between the working air WA and product air PA inlet humidity and the product air PA outlet temperature in the indirect vaporization element 11 is obtained and shown in the graph of FIG.

The conditions of the working air WA and the product air PA input to the indirect vaporization element 11 are the temperature 30 ° C, flow rate fixed at 50m ³ Zhr.

[0088] From FIG. 7, it can be seen that the outlet temperature of the product air PA decreases as the inlet humidity of the working air WA and the product air PA decreases.

[0089] From the above, in the indirect vaporization element 11, the flow rate of the working air WA, the flow rate of the product air PA, the inlet temperature of the working air WA, the inlet temperature of the product air PA, the inlet humidity of the king air WA, the product air It can be seen that the outlet temperature of the inlet duct air PA can be controlled by controlling the humidity at the inlet of the PA.

[0090] <Operation of ventilation device 1A of first embodiment>

Next, the operation of the ventilator 1A of the first embodiment will be described with reference to FIG. In the ventilator 1A, when the air supply fan 2 is driven, a flow of directional air to the air supply outlet 6 is generated in the air supply passage 9A. As a result, the outside air OA is sucked from the outside air suction port 5, passes through the product air flow path l ib of the air purification filter 16 and the indirect vaporization element 11, and is supplied to the room as the supply air SA from the supply air outlet 6.

[0091] When the exhaust fan 3 is driven, a flow of directional force is generated to the exhaust outlet 8 in the exhaust passage 10A. As a result, the return air RA having a strong indoor force is sucked from the return air suction port 7, passes through the working air passage 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust air outlet 8 as the exhaust air EA.

[0092] Therefore, in the ventilator 1A, the outside air OA becomes the product air PA, and the return air RA becomes the boiling air WA.

[0093] As described in FIGS. 2A to 2C, in the indirect vaporization element 11, when the working air WA passing through the working air flow path 1 la is cooled by the vaporization heat of water and the working air WA is cooled, the product Product air PA passing through air flow path l ib is cooled by the cold air of working air WA.

[0094] Since no movement of humidity occurs between the working air flow path 11a and the product air flow path l ib, the outside air OA passing through the product air flow path l ib of the indirect vaporization element 11 is humidity (absolute humidity). ) Does not change and the temperature drops.

Accordingly, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the indoor temperature can be lowered.

[0096] Note that the return air RA that has passed through the working air flow path 11a of the indirect vaporization element 11 becomes high-humidity air, and is thus discharged from the exhaust outlet 8 as exhaust EA.

In the ventilator 1A, the flow rate of the product air PA passing through the product air flow path ib of the indirect vaporization element 11 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Further, the flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjustment damper 15.

[0098] In this way, either the supply air flow adjustment damper 14 or the exhaust flow adjustment damper 15 is operated to adjust the flow rate of the product air PA or the flow rate of the working air WA. As explained, product air PA outlet temperature in indirect vaporization element 11 The degree is controlled. Therefore, the supply air temperature from the supply air outlet 6 is controlled.

That is, when the flow rate of the working air WA is increased by controlling the opening degree of the exhaust flow rate adjusting damper 15, the outlet temperature of the product air PA in the indirect vaporization element 11 is lowered. Therefore, the supply air temperature from the supply air outlet 6 can be lowered.

[0100] If the opening of the exhaust flow adjustment damper 15 is controlled to reduce the flow rate of the working air WA, the outlet temperature of the product air PA in the indirect vaporization element 11 rises.

. Therefore, the supply air temperature from the supply air outlet 6 can be raised.

[0101] Further, if the flow rate of the product air PA is increased by controlling the opening degree of the supply air flow adjustment damper 14, the outlet temperature of the product air PA in the indirect vaporization element 11 rises. Therefore, the supply air temperature from the supply air outlet 6 can be raised.

[0102] Further, if the flow rate of the product air PA is decreased by controlling the opening degree of the supply air flow adjustment damper 14, the outlet temperature of the product air PA in the indirect vaporization element 11 is lowered. Therefore, the supply air temperature from the supply air outlet 6 can be lowered.

[0103] In this way, the supply air temperature can be controlled by adjusting the flow rate of one of the product air PA and the working air WA, so the supply air flow adjustment damper 14 and the exhaust flow adjustment damper

A configuration with any one of 15 is acceptable.

[0104] The product air PA in the indirect vaporization element 11 can also be adjusted by operating both the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 to adjust the flow rate of the product air PA and the flow rate of the working air WA. The outlet temperature is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0105] Furthermore, the flow rate of the product air PA can be adjusted by changing the rotation speed of the supply fan 2, and similarly, the flow volume can be controlled by changing the rotation speed of the exhaust fan 3. The flow rate of working air WA is adjustable.

[0106] Therefore, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled by controlling the power of the supply fan 2 and the exhaust fan 3 or the air volume of both the supply fan 2 and the exhaust fan 3. The supply air temperature from the supply air outlet 6 is controlled.

[0107] Also, the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air flow of at least one of the supply air fan 2 and the exhaust fan 3 may be combined. The outlet temperature of the product air PA in the indirect vaporization element 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

The above-described temperature control can be performed manually with a setting switch described later, or can be automatically adjusted according to the temperature using the temperature sensor 17 or the like.

[0109] The indoor temperature can be lowered by using the ventilator 1A in summer. Therefore, the temperature of the return air RA is also low. As explained in Figure 5, if the working air WA input temperature is low,

Since the outlet temperature of the product air PA decreases, the return air RA can be used as the working air WA to efficiently lower the outlet temperature of the product air PA and control the supply air temperature.

[0110] By using the return air RA, it is possible to cool and take in the outside air while exhausting indoor air to the outdoors, and the ventilator 1A has a function of performing cooling while performing ventilation. Become.

[0111] In recent years, building standards have mandates 24-hour ventilation of buildings. This

Use a ventilator, etc. that can forcibly ventilate using a fan so that the air in the building can be replaced in a predetermined time!

[0112] The ventilator 1A of this example has a function of cooling while performing ventilation. Therefore, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, the air in the building can be replaced in a predetermined time. Such ventilation operation is possible.

FIG. 8 is a configuration diagram showing an example of a ventilation device 1B according to the second embodiment. The ventilation device 1B of the second embodiment uses outside air OA as the working air WA of the indirect vaporization element 11 constituting the indirect vaporization cooling unit 4. In the ventilation device 1B of the second embodiment, the same components as those in the ventilation device 1A of the first embodiment will be described with the same numbers.

[0114] The ventilation device 1B includes an air supply passage 9B that communicates with the air supply outlet 6 from the outside air inlet 5 through the air supply fan 2 and the product air passage l ib of the indirect vaporization element 11.

[0115] Further, the ventilator 1B branches off from the air supply fan 2 on the downstream side of the air supply flow path 9B, passes through the working air flow path 1 la and the exhaust fan 3 of the indirect vaporization element 11, and goes to the exhaust air outlet 8. Communication The first exhaust flow path 10B and the second exhaust flow path 10C that passes from the return air suction port 7 through the exhaust fan 3 and communicates with the exhaust blowout port 8 are provided. A portion indicated by a broken line of the second exhaust passage 10C is formed, for example, along the side wall of the case so as to be independent of the air supply passage 9B.

The supply air flow path 9B includes an intake air flow rate adjusting damper 14 on the downstream side of the branch position with the first exhaust flow path 10B, for example, on the upstream side of the indirect vaporization cooling unit 4. The first exhaust channel 1

The OB is provided with an exhaust flow rate adjusting damper 15 on the downstream side of the branch position with the supply air flow path 9B, for example, on the upstream side of the indirect evaporative cooling unit 4.

[0117] By adjusting the opening of the supply air flow adjustment damper 14, the flow rate of the air flowing through the supply air passage 9B is adjusted. As a result, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0118] Further, by adjusting the opening degree of the exhaust flow rate adjusting damper 15, the flow rate of the air flowing through the first exhaust flow path 10B is adjusted. As a result, the flow rate of the working air WA flowing through the working air flow path 1 la of the indirect vaporization element 11 is adjusted.

[0119] Note that the air supply passage 9B includes, for example, an air purification filter 16 on the upstream side from the branch position with the first exhaust passage 10B. Furthermore, the air supply passage 9B includes a temperature sensor 17 at the air supply outlet 6.

Next, the operation of the ventilator 1B of the second embodiment will be described with reference to FIG. When the air supply fan 2 is driven, the ventilation device 1B generates a flow of directional air to the air supply outlet 6 in the air supply passage 9B. As a result, the outside air OA is sucked from the outside air suction port 5, passes through the product air flow path l ib of the indirect vaporization element 11, and is supplied to the room as the supply air SA from the supply air outlet 6.

[0121] Further, when the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10B and the second exhaust passage 10C. As a result, a part of the outside air OA passes through the working air passage 11a of the indirect vaporization element 11 by the first exhaust passage 10B, and is discharged to the outdoors from the exhaust outlet 8 as exhaust EA. Further, the return air RA from the room is sucked in from the return air suction port 7 through the second exhaust flow path 10 C, and is discharged to the outside as the exhaust air EA from the exhaust air outlet 8. [0122] Therefore, in the ventilator IB, the outside air OA becomes the product air PA and the working air WA.

[0123] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. Outside air that has passed through OA, the humidity (absolute humidity) does not change and the temperature drops.

[0124] Accordingly, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the temperature in the room can be lowered.

[0125] Since the outside air OA that has passed through the working air flow path 11a of the indirect vaporization element 11 becomes high-humidity air, it is discharged from the exhaust outlet 8 as exhaust EA.

[0126] In the ventilator 1B, similar to the ventilator 1A of the first embodiment, the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is determined by the opening degree of the supply air flow adjustment dan 14. The flow rate is adjusted. Further, the flow rate of the working air WA passing through the working air flow path 1 la of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjusting damper 15.

[0127] In this way, either or both of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 are operated to adjust the flow rate of the product air PA, the flow rate of the working air WA, or the flow rate of both. As described in FIGS. 3 and 4, the outlet temperature of the product air PA in the indirect vaporization element 11mm is controlled. Thus, the supply air temperature from the supply air outlet 6 is controlled.

[0128] Further, the flow rate of the product air PA can be adjusted by changing the rotation speed of the supply fan 2, and similarly, the flow volume can be controlled by changing the rotation speed of the exhaust fan 3. The flow rate of working air WA is adjustable.

[0129] Therefore, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled by controlling the power of the air supply fan 2 and the exhaust fan 3 or the air volume of both the air supply fan 2 and the exhaust fan 3. The supply air temperature from the supply air outlet 6 is controlled.

[0130] Further, the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust air flow adjustment damper 15 and the control of the air volume of at least one of the supply air fan 2 and the exhaust fan 3 may be combined. The outlet temperature of the product air PA in the indirect vaporization element 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0131] The ventilator 1B has a function of exhausting the return air RA to the outside, so that the outside air can be cooled and taken in while the indoor air is exhausted to the outside. It will have the function of cooling.

[0132] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, a ventilation operation in which the air in the room is replaced in a predetermined time is possible.

FIG. 9 is a configuration diagram illustrating an example of a ventilation device 1C according to the third embodiment. The ventilator 1C of the third embodiment includes an air supply passage that bypasses the indirect evaporative cooling unit 4. In the ventilator 1C of the third embodiment, the same components as those in the ventilator 1A of the first embodiment will be described with the same numbers.

The ventilator 1C includes an air supply passage 9C that communicates from the outside air inlet 5 to the air supply outlet 6 through the air supply fan 2 and the product air passage l ib of the indirect vaporization element 11. Exhaust flow path 1

The OA has the same configuration as the ventilator 1A of the first embodiment.

[0135] In addition, the ventilator 1C has a supply air flow path 9C that branches upstream of the indirect vaporization cooling unit 4 and bypasses the indirect vaporization cooling unit 4 to communicate with the supply air outlet 6 to the binos flow path 10

D is provided.

The bypass flow path 10D includes a supply air flow rate adjustment damper 18. The supply air flow adjusting damper 18 constitutes a flow control means, and includes a damper that adjusts the air flow rate by opening and closing and a motor that drives the damper. By adjusting the opening of the supply air flow adjusting damper 18, The flow rate of air flowing through the road 1 OD is adjusted. As a result, the flow rate of air supplied to the supply air outlet 6 while bypassing the indirect vaporization cooling unit 4 is adjusted.

[0137] Note that the air supply flow path 9C includes an air purification filter 16 on the upstream side of the branch position with the bypass flow path 10D, for example.

[0138] <Operation of Ventilator 1C of Third Embodiment>

Next, the operation of the ventilator 1C according to the third embodiment will be described with reference to FIG. When the air supply fan 2 is driven, the ventilator 1C moves to the air supply outlet 6 in the air supply passage 9C. Force A flow of air is generated. As a result, outside air OA is sucked from the outside air inlet 5.

Then, it passes through the product air flow path l ib of the indirect vaporization element 11 and is supplied into the room as the supply air SA from the supply air outlet 6.

[0139] When the exhaust fan 3 is driven, a flow of directional force to the exhaust outlet 8 is generated in the exhaust passage 10A. As a result, the return air RA having a strong indoor force is sucked from the return air suction port 7, passes through the working air passage 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust air outlet 8 as the exhaust air EA.

[0140] Therefore, in the ventilator 1C, the outside air OA becomes the product air PA, and the return air RA becomes the boiling air WA.

[0141] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity).

[0142] Thus, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the temperature in the room can be lowered.

[0143] In the ventilator 1C, the flow rate of the air flowing through the bypass channel 10D is adjusted by adjusting the opening degree of the supply air flow rate adjustment damper 18.

Thereby, the flow rate of the air supplied to the supply air outlet 6 while bypassing the indirect vaporization cooling unit 4 is adjusted.

[0145] Therefore, by operating the supply air flow rate adjusting damper 18 and adjusting the flow rate of the air flowing through the bypass flow path 10D, the air cooled through the indirect evaporative cooling unit 4 and the indirect evaporative cooling unit 4 The air mixing ratio is controlled and the supply air temperature from the supply air outlet 6 is controlled.

[0146] By using return air RA, ventilator 1C can cool and take in outside air while venting indoor air to the outside. Ventilator 1C is a device that cools air while ventilating. Will have the ability.

[0147] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, a ventilation operation in which the air in the room is replaced in a predetermined time is possible. <Configuration of Ventilator ID of Fourth Embodiment>

FIG. 10A is a configuration diagram illustrating an example of a ventilation device 1D according to the fourth embodiment. The ventilator 1D of the fourth embodiment includes a heat exchange unit 31 in addition to the air supply fan 2, the exhaust fan 3, and the indirect evaporative cooling unit 4. In the ventilator 1D of the fourth embodiment, the same components as those of the ventilator 1A of the first embodiment will be described with the same numbers.

[0149] The heat exchange unit 31 includes a heat exchange element 32 and a filter (not shown). The heat exchange element 32 includes a heat exchange element material in which the first flow path 32a is formed and a heat exchange element material in which the second flow path 32b is formed, and the first flow path 32a and the second flow path 32b. Is a cross-flow heat exchanger that is stacked in a direction perpendicular to each other. The first channel 32a and the second channel 32b are cut off by a partition (not shown), and sensible heat exchange is performed between the air supplied to the first channel 32a and the second channel 32b.

[0150] The air supply flow path 9D is an indirect vaporizer that forms the air supply fan 2, the first flow path 32a of the heat exchange element 32 constituting the heat exchange unit 31 and the indirect vaporization cooling unit 4 from the outside air inlet 5 It passes through 1 lb of the product air flow path of Rement 11 and communicates with the supply air outlet 6.

[0151] The first exhaust passage 10E communicates from the return air suction port 7 to the exhaust outlet 8 through the working air passage 11a of the indirect vaporization element 11 and the exhaust fan 3. The second exhaust passage 1 OF communicates from the return air inlet 7 to the exhaust outlet 8 through the second passage 32b of the heat exchange element 32 and the exhaust fan 3.

[0152] The air supply passage 9D includes, for example, an air supply flow rate adjustment damper 14 on the upstream side of the heat exchange unit 31. By adjusting the opening of the supply air flow adjustment damper 14, the flow rate of the air flowing through the supply air flow passage 9D is adjusted. Thereby, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0153] The first exhaust flow path 10E includes an exhaust flow rate adjustment damper 15 on the upstream side of the indirect evaporative cooling unit 4, for example. By adjusting the opening of the exhaust flow rate adjustment damper 15, the flow rate of the air flowing through the first exhaust flow channel 10E is adjusted. As a result, the flow rate of the working air WA flowing through the shaking air flow path 11a of the indirect vaporization element 11 is adjusted.

[0154] In addition, the air supply flow path 9D includes, for example, an air purification filter 16 on the upstream side of the heat exchange unit 31. Prepare. By disposing the air purifying filter 16 on the upstream side of the heat exchange unit 31, dust and the like can be prevented from entering the heat exchange element 32 and the indirect vaporization element 11.

Furthermore, the supply air flow path 9D includes a temperature sensor 17 at the supply air outlet 6 to detect the supply air temperature.

Next, the operation of the ventilator 1D of the fourth embodiment will be described with reference to FIG. 10A and the like. When the air supply fan 2 is driven, the ventilation device 1D generates a flow of directional air to the air supply outlet 6 in the air supply passage 9D. As a result, outside air OA is sucked from the outside air inlet 5 and passes through the air purification filter 16, the first flow path 32a of the heat exchange element 32, and the product air flow path l ib of the indirect vaporization element 11, and the supply air blown. It is supplied indoors as supply air SA from outlet 6.

[0157] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10E and the second exhaust passage 10F. As a result, the return air RA from the room is sucked in from the return air suction port 7, passes through the working air flow path 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust outlet 8 as exhaust EA. Further, a part of the return air RA passes through the second flow path 32b of the heat exchange element 32, and is discharged to the outside from the exhaust outlet 8 as exhaust EA.

[0158] Therefore, in the ventilator 1D, the outside air OA becomes the product air PA, and the return air RA becomes the boiling air WA.

[0159] In the heat exchange element 32, heat exchange is performed between the outside air OA passing through the first flow path 32a and the return air RA passing through the second flow path 32b. By using the ventilator 1D in summer, the indoor temperature is lowered, and the temperature of the return air RA is lower than the temperature of the outside air OA.

Accordingly, the temperature of the outside air OA that has passed through the first flow path 32a of the heat exchange element 32 decreases, and the temperature of the return air RA that has passed through the second flow path 32b increases.

[0161] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity). [0162] Accordingly, the outside temperature OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the temperature in the room can be lowered.

Here, the temperature of the outside air OA passing through the product air flow path l ib of the indirect vaporization element 11 is lowered by the heat exchange unit 31 in the previous stage. As shown in Fig. 5, if the product air PA input temperature is low, the product air PA outlet temperature decreases, so the heat exchange unit 31 is placed in front of the indirect evaporative cooling unit 4 to By reducing the input temperature of the air PA, the outlet temperature of the product air PA can be lowered efficiently and the supply air temperature can be controlled.

[0164] Also, as explained in Fig. 5, if the input temperature of the working air WA is low, the outlet temperature of the product air PA will drop, so the return air RA can be used efficiently as the working air WA. Product air PA outlet temperature can be lowered to control supply air temperature

[0165] Note that the return air RA that has passed through the working air flow path 11a of the indirect vaporization element 11 becomes high-humidity air, and is discharged from the exhaust outlet 8 as exhaust EA. Further, since the temperature of the return air RA passing through the second flow path 32b of the heat exchange element 32 rises, it is discharged from the exhaust outlet 8 as exhaust EA.

[0166] In the ventilator 1D, the flow rate of the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Further, the flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjustment damper 15.

[0167] As a result, even in the ventilator 1D equipped with the heat exchange unit 31, either the supply air flow adjustment damper 14 or the exhaust air flow adjustment damper 15 is activated to reduce the flow rate of the product air PA or the flow of the combustion air WA. By adjusting, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled as described in FIGS. Therefore, the supply air temperature from the supply air outlet 6 is controlled.

[0168] For example, when the flow rate of the working air WA is increased, the outlet temperature of the product air PA in the indirect vaporization element 11 is lowered, so that the supply air temperature from the supply air outlet 6 can be lowered. [0169] In addition, when the flow rate of the working air WA is decreased, the outlet temperature of the outlet duct air PA in the indirect vaporization element 11 increases, so that the supply air temperature from the supply air outlet 6 can be increased. .

[0170] Since the supply air temperature can be controlled by adjusting the flow rate of either product air PA or working air WA, either the supply air flow adjustment damper 14 or the exhaust flow adjustment damper 15 is provided. Configuration is also good! ,.

[0171] In addition, by operating both the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 to adjust the flow rate of the product air PA and the flow rate of the working air WA, the product air PA in the indirect vaporization element 11 is adjusted. The outlet temperature is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0172] Furthermore, the flow rate of the product air PA can be adjusted by changing the rotation speed of the supply fan 2, and similarly, the flow volume can be controlled by changing the rotation speed of the exhaust fan 3. The flow rate of working air WA is adjustable.

[0173] Therefore, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled by controlling the power of the air supply fan 2 and the exhaust fan 3 or the air volume of both the air supply fan 2 and the exhaust fan 3. The supply air temperature from the supply air outlet 6 is controlled.

[0174] Further, the indirect vaporization element can be obtained by combining the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air volume of at least one of the supply air fan 2 and the exhaust fan 3. The outlet temperature of the product air PA in 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0175] FIG. 10B shows a comparative example of a configuration with the heat exchange unit 31 and a configuration without the heat exchange unit 31. First, in the configuration without the heat exchange unit 31, the outside air of 40 ° C is used. From the graph shown in Fig. 5, it can be seen that the supply air SA of 21 ° C can be generated when OA is introduced and cooled by the indirect evaporative cooling unit 4, but at the same time, as shown in Fig. 6, 0.48 kgZhr of water is consumed. .

[0176] Therefore, it was decided to insert a heat exchange unit 31 that lowers the temperature of the taken-in outside air OA. The heat exchanging element 32 constituting the heat exchanging unit 31 generally has a heat exchanging rate of about 70%, and heat is exchanged between 40 ° C outside air OA and 25 ° C return air RA (indoor air). Then heat With an exchange efficiency of 70%, 29.5 ° C air can be supplied to the indirect evaporative cooling unit 4.

[0177] When supplied as product air PA and working air WA of indirect vaporization element 11 under these conditions, supply air SA of 17 ° C can be generated, and water consumption can be suppressed to 0.32 kgZhr. Half U.

[0178] As a result, the ventilator 1D includes the heat exchange unit 31, and by using the return air RA in the heat exchange unit 31 and the indirect evaporative cooling unit 4, the cooling capacity is improved and water consumption is increased. Can be suppressed. In addition, by using the return air RA, it is possible to cool and take in outside air while exhausting indoor air to the outdoors, and the ventilator 1D has a function of performing cooling while performing ventilation.

[0179] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, a ventilation operation that replaces the air in the room in a predetermined time is possible.

[0180] <Configuration of Ventilator 1E of Fifth Embodiment>

FIG. 11 is a configuration diagram illustrating an example of a ventilation device 1E according to the fifth embodiment. The ventilator 1E of the fifth embodiment uses outside air OA as the working air WA of the indirect vaporization element 11 constituting the indirect vaporization cooling unit 4 in the ventilator 1E having the heat exchange unit 31. . In the ventilator 1E of the fifth embodiment, the same components as those of the ventilator 1D of the fourth embodiment will be described with the same numbers.

[0181] The ventilator 1E passes from the outside air inlet 5 to the air supply fan 2, the first flow path 32a of the heat exchange element 32, and the product air flow path l ib of the indirect vaporization element 11 to the air supply outlet 6 Provided with a supply air flow path 9E.

[0182] In addition, the ventilator 1E branches off from the heat exchange unit 31 with the air supply passage 9E, passes through the working air passage 11a of the indirect vaporization element 11 and the exhaust fan 3, and communicates with the exhaust outlet 8 The first exhaust flow path 10G and the second exhaust flow path 10H communicated from the return air suction port 7 to the exhaust air outlet 8 through the second flow path 32b of the heat exchange element 32 and the exhaust fan 3. The

The supply air flow path 9E includes an intake air flow rate adjustment damper 14 on the upstream side of the heat exchange unit 31, for example. The first exhaust flow path 10G includes an exhaust flow rate adjustment damper 15 on the downstream side of the branch position with the supply air flow path 9E, for example, on the upstream side of the indirect vaporization cooling unit 4. [0184] By adjusting the opening degree of the supply air flow adjustment damper 14, the flow rate of the air flowing through the supply air flow path 9E is adjusted. As a result, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0185] Further, by adjusting the opening degree of the exhaust flow rate adjustment damper 15, the flow rate of the air flowing through the first exhaust flow path 10G is adjusted. As a result, the flow rate of the working air WA flowing through the working air flow path 1 la of the indirect vaporization element 11 is adjusted.

Note that the air supply flow path 9E includes an air purifying filter 16 on the upstream side of the heat exchange unit 31, for example. Further, the air supply passage 9E includes a temperature sensor 17 at the air supply outlet 6.

Next, the operation of the ventilator 1E of the fifth embodiment will be described with reference to FIG. When the air supply fan 2 is driven, the ventilation device 1E generates a flow of directional air to the air supply outlet 6 in the air supply passage 9E. As a result, the outside air OA is sucked from the outside air inlet 5 and passes through the first flow path 32a of the heat exchange element 32 and the product air flow path l ib of the indirect vaporization element 11, and is supplied from the supply air outlet 6 to the supply air SA. Is supplied indoors.

[0188] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10G and the second exhaust passage 10H. As a result, a part of the outside air OA passes through the working air passage 11a of the indirect vaporization element 11 by the first exhaust passage 10G, and is discharged to the outside from the exhaust outlet 8 as the exhaust EA. In addition, the return air RA from the room is sucked in from the return air inlet 7 by the second exhaust passage 10H, passes through the second passage 32b of the heat exchange element 32, and becomes exhaust EA from the exhaust outlet 8 It is discharged outdoors.

[0189] Therefore, in the ventilation device 1E, the outside air OA becomes the product air PA and the working air WA.

[0190] In the heat exchange element 32, heat is exchanged between the outside air OA passing through the first flow path 32a and the return air RA passing through the second flow path 32b. By using the ventilator 1E in summer, the indoor temperature is lowered, and the temperature of the return air RA is lower than the temperature of the outside air OA.

[0192] As described above, in the indirect vaporization element 11, the working air WA is generated by the heat of vaporization of water. Since the product air PA is cooled and cooled by the cold heat of the working air WA, the temperature of the outside air OA passing through the product air flow path l ib falls without changing the humidity (absolute humidity).

[0193] Thus, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the temperature in the room can be lowered.

[0194] Here, the temperature of the outside air OA passing through the product air flow path l ib of the indirect vaporization element 11 is lowered by the heat exchange unit 31 in the previous stage. As shown in Fig. 5, if the product air PA input temperature is low, the product air PA outlet temperature decreases, so the heat exchange unit 31 is placed in front of the indirect evaporative cooling unit 4 to By reducing the input temperature of the air PA, the outlet temperature of the product air PA can be lowered efficiently and the supply air temperature can be controlled.

[0195] In addition, as described in FIG. 5, when the working air WA input temperature is low, the outlet temperature of the product air PA decreases, so a part of the outside air OA cooled by the heat exchange unit 31 is shared. By using it as King Air WA, the outlet temperature of the product air PA can be lowered efficiently and the supply air temperature can be controlled.

[0196] Since the outside air OA that has passed through the working air flow path 11a of the indirect vaporization element 11 becomes high-humidity air, it is discharged from the exhaust outlet 8 as exhaust EA. Further, since the temperature of the return air RA passing through the second flow path 32b of the heat exchange element 32 rises, it is discharged from the exhaust outlet 8 as exhaust EA.

[0197] In the ventilator 1E, similar to the ventilator 1D of the fourth embodiment, the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is determined by the opening degree of the supply air flow rate adjusting dan 14. The flow rate is adjusted. Further, the flow rate of the working air WA passing through the working air flow path 1 la of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjusting damper 15.

[0198] In this way, either or both of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 are operated to adjust the flow rate of the product air PA, the flow rate of the working air WA, or the flow rate of both. As described in FIGS. 3 and 4, the outlet temperature of the product air PA in the indirect vaporization element 11mm is controlled. Therefore, supply air from supply air outlet 6 The temperature is controlled.

[0199] Further, the flow rate of the product air PA can be adjusted by changing the rotation speed of the supply fan 2, and similarly, the flow volume can be controlled by changing the rotation speed of the exhaust fan 3. The flow rate of working air WA is adjustable.

[0200] Therefore, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled by controlling the power of the air supply fan 2 and the exhaust fan 3 or the air volume of both the air supply fan 2 and the exhaust fan 3. The supply air temperature from the supply air outlet 6 is controlled.

[0201] The indirect vaporization element can be obtained by combining the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air flow of at least one of the supply air fan 2 and the exhaust fan 3. The outlet temperature of the product air PA in 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0202] The ventilator 1E includes a heat exchange unit 31, and uses the return air RA in the heat exchange unit 31 and uses the OA cooled in the heat exchange unit 31 in the indirect vaporization cooling unit 4 to cool the air. Ability improves. In addition, by using the return air RA, it is possible to cool and take in outside air while exhausting indoor air to the outdoors, and the ventilator 1E has a function of cooling while ventilating.

[0203] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, a ventilation operation in which the air in the room is replaced in a predetermined time is possible.

[0204] <Configuration of ventilation device 1F of sixth embodiment>

FIG. 12 is a configuration diagram illustrating an example of a ventilation device 1F according to the sixth embodiment. A ventilator 1F according to the sixth embodiment includes an air supply passage that bypasses the indirect evaporative cooling unit 4 in the ventilator 1F that includes the heat exchange unit 31. Note that in the ventilation device 1F according to the sixth embodiment, the same components as those in the ventilation device 1D according to the fourth embodiment are denoted by the same reference numerals.

[0205] The ventilator 1F passes through the air intake port 5 through the air supply fan 2, the first flow path 3 2a of the heat exchange element 32, and the product air flow path l ib of the indirect vaporization element 11, and the air supply outlet 6 Air supply passage 9F communicating with The first exhaust flow path 10E and the second exhaust flow path 10F have the same configuration as the ventilation device 1D of the fourth embodiment. [0206] Further, the ventilator IF includes a bypass passage 101 that branches from the air supply passage 9F upstream of the indirect vaporization cooling unit 4 and communicates with the air supply outlet 6 by bypassing the indirect vaporization cooling unit 4 .

The bypass channel 101 includes a supply air flow rate adjustment damper 18. The flow rate of the air flowing through the bypass passage 101 is adjusted by adjusting the opening degree of the supply air flow adjusting damper 18. As a result, the flow rate of the air supplied to the supply air outlet 6 bypassing the indirect evaporative cooling unit 4 is adjusted.

[0208] Note that the air supply passage 9F includes an air purifying filter 16 on the upstream side of the heat exchange unit 31, for example.

[0209] <Operation of Ventilator 1F of Sixth Embodiment>

Next, the operation of the ventilation device 1F according to the sixth embodiment will be described with reference to FIG. In the ventilation device 1F, when the air supply fan 2 is driven, a flow of directional air to the air supply outlet 6 is generated in the air supply passage 9F. As a result, the outside air OA is sucked in from the outside air inlet 5, passes through the first channel 32a of the heat exchange element 32 and the product air channel l ib of the indirect vaporization element 11, and is supplied from the supply air outlet 6 to the supply air SA. Is supplied indoors.

[0210] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10E and the second exhaust passage 10F. As a result, the return air RA from the room is sucked in from the return air suction port 7, passes through the working air flow path 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust outlet 8 as exhaust EA. Further, a part of the return air RA passes through the second flow path 32b of the heat exchange element 32, and is discharged to the outside from the exhaust outlet 8 as exhaust EA.

[0211] Therefore, in the ventilator 1F, the outside air OA becomes the product air PA, and the return air RA becomes the boiling air WA.

[0212] In the heat exchange element 32, heat exchange is performed between the outside air OA passing through the first flow path 32a and the return air RA passing through the second flow path 32b. By using the ventilator 1F in summer, the indoor temperature is lowered, and the temperature of the return air RA is lower than the temperature of the outside air OA.

[0213] Therefore, the temperature of the outside air OA that has passed through the first flow path 32a of the heat exchange element 32 decreases, and the temperature of the return air RA that has passed through the second flow path 32b increases. [0214] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity).

[0215] Accordingly, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the temperature in the room can be lowered.

[0217] Also, as explained in Fig. 5, if the input temperature of the working air WA is low, the outlet temperature of the product air PA decreases. Therefore, the return air RA is used as the working air WA, so that the product air PA is used. The outlet temperature can be lowered to lower the supply air temperature.

[0218] In the ventilator 1F, the flow rate of the air flowing through the bypass passage 101 is adjusted by adjusting the opening degree of the supply air flow rate adjustment damper 18.

[0219] Thereby, the flow rate of the air supplied to the supply air outlet 6 while bypassing the indirect vaporization cooling unit 4 is adjusted.

[0220] Therefore, the air cooled through the indirect evaporative cooling unit 4 and the indirect evaporative cooling unit 4 by adjusting the flow rate of the air flowing through the bypass flow path 101 by operating the supply air flow adjusting damper 18 and the indirect evaporative cooling unit 4 Indirect evaporative cooling unit 4 is bypassed and the mixing ratio of the soot that has been cooled is controlled, and the temperature of the supply air from supply air outlet 6 is controlled.

[0221] The ventilation device 1F includes the heat exchange unit 31, and the cooling capacity is improved by using the return air RA in the heat exchange unit 31 and the indirect evaporative cooling unit 4. In addition, by using the return air RA, it is possible to cool and take in outside air while exhausting indoor air to the outdoors, and the ventilator 1F has a function of cooling while ventilating.

[0222] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, the room is emptied in a predetermined time. Ventilation operation that changes mind is possible.

[0223] <Configuration of ventilation device 1G of the seventh embodiment>

FIG. 13A is a configuration diagram showing an example of a ventilation device 1G according to the seventh embodiment. The ventilation device 1G of the seventh embodiment includes a dehumidifying unit 33 in addition to the air supply fan 2, the exhaust fan 3, and the indirect evaporative cooling unit 4. Note that in the ventilator 1G of the seventh embodiment, the same components as those of the ventilator 1A of the first embodiment will be described with the same numbers.

[0224] The dehumidifying unit 33 includes a dehumidifying channel 35a and a regeneration channel 35b partitioned by a partition wall 34, a dehumidifying rotor 36 that is rotationally driven across the dehumidifying channel 35a and the regeneration channel 35b, and a regeneration channel 35b. A heater 37 that heats the air passing through and a rotational drive device (not shown) that rotationally drives the dehumidification rotor 36 are provided.

[0225] The dehumidification rotor 36 is configured in a disc shape so that a flow path communicating in the member force axial direction of a hard cam structure having an adsorbent such as silica gel is formed. The dehumidifying rotor 36 is disposed across the dehumidifying channel 35a and the regeneration channel 35b, and the air passing through the dehumidifying channel 35a and the air passing through the regeneration channel 35b pass through the dehumidifying rotor 36, respectively.

Note that in the dehumidification rotor 36, the dehumidification channel 35a and the regeneration channel 35b are partitioned by the partition wall 34, and the air passing through the dehumidification channel 35a and the air passing through the regeneration channel 35b are not mixed.

[0227] In the air passing through the dehumidifying channel 35a, moisture is adsorbed by the dehumidifying rotor 36 and dehumidified. When the dehumidification port 36 is driven to rotate, the portion that has adsorbed moisture moves to the regeneration channel 35b side. The air passing through the regeneration channel 35b is heated by the heater 37, whereby the dehumidification rotor 36 is heated by the air passing through the regeneration channel 35b, the water is evaporated, and the water is regenerated so that the water can be adsorbed again.

[0228] Then, the regenerated portion of the dehumidifying rotor 36 moves to the dehumidifying channel 35a side. As a result, the dehumidifying unit 33 rotates the dehumidifying rotor 36 to dehumidify the air passing through the dehumidifying channel 35a while repeating the adsorption and regeneration of moisture.

[0229] The air supply passage 9G communicates from the outside air intake port 5 to the air supply outlet 2 through the air supply fan 2, the dehumidification passage 35a of the dehumidification unit 33, and the product air passage l ib of the indirect vaporization element 11. To do.

[0230] The first exhaust passage 10J is connected to the return air suction port 7 through the working air of the indirect vaporization element 11. It passes through the flow path 11a and the exhaust fan 3 and communicates with the exhaust outlet 8. The second exhaust passage 1 OK communicates from the return air inlet 7 to the exhaust outlet 8 through the regeneration passage 35b of the dehumidifying unit 33 and the exhaust fan 3.

The air supply flow path 9G includes an air supply flow rate adjustment damper 14 on the upstream side of the dehumidifying unit 33, for example. By adjusting the opening degree of the supply air flow adjustment damper 14, the flow rate of the air flowing through the supply air passage 9G is adjusted. As a result, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0232] The first exhaust flow path 10J includes an exhaust flow rate adjustment damper 15 on the upstream side of the indirect evaporative cooling unit 4, for example. By adjusting the opening of the exhaust flow rate adjustment damper 15, the flow rate of the air flowing through the first exhaust flow channel 10J is adjusted. As a result, the flow rate of the working air WA flowing through the burning air flow path 11a of the indirect vaporization element 11 is adjusted.

[0233] The air supply flow path 9G includes an air purifying filter 16 on the upstream side of the dehumidifying unit 33, for example. By disposing the air purifying filter 16 on the upstream side of the dehumidifying unit 33, intrusion of dust or the like into the dehumidifying rotor 36 and the indirect vaporizing element 11 is prevented.

Furthermore, the supply air flow path 9G includes a temperature sensor 17 at the supply air outlet 6 so that the supply air temperature is detected.

[0235] <Operation of Ventilator 1G of Seventh Embodiment>

Next, the operation of the ventilator 1G of the seventh embodiment will be described with reference to FIG. 13A and the like. When the air supply fan 2 is driven, the ventilation device 1G generates a flow of directional air to the air supply outlet 6 in the air supply passage 9G. As a result, the outside air OA is sucked in from the outside air inlet port 5, passes through the air purification filter 16, the dehumidifying channel 35 a of the dehumidifying unit 33 and the product air channel l ib of the indirect vaporizing element 11, and is supplied from the air supply outlet 6. Qi is supplied indoors as SA.

[0236] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10J and the second exhaust passage 10K. As a result, the return air RA from the room is sucked in from the return air suction port 7, passes through the working air flow path 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust outlet 8 as exhaust EA. In addition, a part of the return air RA passes through the regeneration channel 35b of the dehumidifying unit 33, and is outdoor as exhaust EA from the exhaust outlet 8. To be discharged.

[0237] Therefore, in the ventilation device 1G, the outside air OA becomes the product air PA and the return air RA becomes the boiling air WA.

[0238] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity).

[0239] Accordingly, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the temperature in the room can be lowered.

Here, the humidity of the outside air OA passing through the product air flow path l ib of the indirect vaporization element 11 is lowered by the dehumidifying unit 33 in the preceding stage. As a result, as described in FIG. 7, if the input humidity of the product air PA is low, the outlet temperature of the product air PA is lowered. Therefore, the dehumidifying unit 33 is arranged in front of the indirect evaporative cooling unit 4 to By reducing the input humidity of the PA, the outlet temperature of the product air PA can be lowered efficiently and the supply air temperature can be controlled.

[0241] In addition, the indoor temperature can be lowered by using the ventilation device 1G in summer. Therefore, the temperature of the return air RA is also low. As explained in Fig. 5, when the working air WA input temperature is low, the outlet temperature of the product air PA decreases. Therefore, the return air RA is used as the working air WA, so that the outlet of the product air PA can be efficiently used. It is possible to control the supply air temperature by lowering the temperature.

[0242] The return air RA through the working air passage 11a of the indirect vaporization element 11 and the return air RA through the regeneration passage 35b of the dehumidifying unit 33 become high-humidity air. Exhaust as exhaust EA.

[0243] In the ventilation device 1G, the flow rate of the product air PA passing through the product air flow path ib of the indirect vaporization element 11 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Further, the flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjustment damper 15.

[0244] Thus, even with the ventilation device 1G having the dehumidifying unit 33, the supply air flow rate adjusting damper 14 and By operating one of the exhaust flow rate adjustment dampers 15 and adjusting the flow rate of the product air PA or the flow rate of the cooling air WA, the product air PA in the indirect vaporization element 11 is adjusted as described in FIGS. The outlet temperature is controlled. Therefore, the supply air temperature from the supply air outlet 6 is controlled.

[0245] For example, when the flow rate of the working air WA is increased, the outlet temperature of the product air PA in the indirect vaporization element 11 is lowered, so that the supply air temperature from the supply air outlet 6 can be lowered.

[0246] In addition, when the flow rate of the working air WA is decreased, the outlet temperature of the outlet duct air PA in the indirect vaporization element 11 increases, so that the supply air temperature from the supply air outlet 6 can be increased. .

[0247] Since the supply air temperature can be controlled by adjusting the flow rate of either product air PA or working air WA, either the supply air flow adjustment damper 14 or the exhaust flow adjustment damper 15 is provided. Configuration is also good! ,.

[0248] In addition, by operating both the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 to adjust the flow rate of the product air PA and the flow rate of the working air WA, the product air PA in the indirect vaporization element 11 is obtained. The outlet temperature is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0249] Further, the flow rate of the product air PA can be adjusted by changing the rotation speed of the supply fan 2, and similarly, the flow volume can be controlled by changing the rotation speed of the exhaust fan 3. The flow rate of working air WA is adjustable.

[0250] Therefore, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled by controlling the power of the supply fan 2 and the exhaust fan 3, or the air volume of both the supply fan 2 and the exhaust fan 3. The supply air temperature from the supply air outlet 6 is controlled.

[0251] The indirect vaporization element can also be obtained by combining the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air volume of at least one of the supply air fan 2 and the exhaust fan 3. The outlet temperature of the product air PA in 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0252] The effect of the configuration provided with the dehumidifying unit 33 is shown in FIG. 13B. Humidity 10gZkg (DA), outside air QA power with relative humidity approx. 40% RH QA power input of dehumidification unit 33 through dehumidification channel 35a, temperature 40 ° C, absolute humidity 5gZkg (DA), relative humidity approx. 10% RH Air.

Here, the temperature of the input air rises because the dehumidification rotor 36 in the dehumidification unit 33 is heated by the heater 37 on the regeneration flow path 35b side.

[0254] If the input air under this condition is the product air PA and the cooking air WA of the indirect evaporative cooling unit 4, the outlet temperature of the product air PA will drop to 20 ° C because the input humidity (absolute humidity) is low. Since the absolute humidity is as low as 5gZkg (DA), there is room for the outlet temperature to further decrease.

[0255] Thereby, the ventilation device 1G includes the dehumidifying unit 33, and the cooling capacity is improved by using the return air RA in the indirect evaporative cooling unit 4. In addition, by using the return air RA, it is possible to cool and take in the outside air while exhausting the indoor air to the outdoors, and the ventilator 1G has a function of cooling while performing ventilation.

[0256] By adjusting the flow rate of the return air RA and the flow rate of the supply air SA, it is possible to perform a ventilation operation in which the air in the room is replaced in a predetermined time.

FIG. 14 is a configuration diagram illustrating an example of a ventilation device 1H according to the eighth embodiment. In the ventilator 1H of the eighth embodiment, in the ventilator 1H having the dehumidifying unit 33, the outside air OA is used as the working air WA of the indirect vaporization element 11 constituting the indirect vaporization cooling unit 4. In the ventilation device 1H according to the eighth embodiment, the same components as those in the ventilation device 1G according to the seventh embodiment are denoted by the same reference numerals.

[0258] The ventilator 1H communicates from the outside air intake port 5 to the supply air outlet 6 through the supply air fan 2, the dehumidification channel 35a of the dehumidification unit 33, and the product air channel l ib of the indirect vaporization element 11. Provided with air supply channel 9H.

[0259] Further, the ventilator 1H branches from the air supply passage 9H downstream from the dehumidification unit 33, and communicates with the exhaust outlet 8 through the working air passage 11a of the indirect vaporization element 11 and the exhaust fan 3. A first exhaust passage 10L and a second exhaust passage 10M communicating from the return air suction port 7 through the regeneration passage 35b of the dehumidifying unit 33 and the exhaust fan 3 to the exhaust outlet 8 are provided. [0260] The air supply flow path 9H includes an air supply flow rate adjustment damper 14 on the upstream side of the dehumidifying unit 33, for example. The first exhaust flow path 10L includes an exhaust flow rate adjustment damper 15 on the downstream side of the branch position with the supply air flow path 9H, for example, on the upstream side of the indirect vaporization cooling unit 4.

[0261] By adjusting the opening of supply air flow adjustment damper 14, the flow rate of air flowing through supply air passage 9H is adjusted. As a result, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0262] Further, by adjusting the opening degree of the exhaust flow rate adjustment damper 15, the flow rate of the air flowing through the first exhaust flow path 10L is adjusted. As a result, the flow rate of the working air WA flowing through the working air flow path 1 la of the indirect vaporization element 11 is adjusted.

[0263] Note that the air supply passage 9H includes an air purifying filter 16 on the upstream side of the dehumidifying unit 33, for example. Further, the air supply passage 9H includes a temperature sensor 17 at the air supply outlet 6.

Next, the operation of the ventilator 1H of the eighth embodiment will be described with reference to FIG. In the ventilation device 1H, when the air supply fan 2 is driven, a flow of directional air to the air supply outlet 6 is generated in the air supply passage 9H. As a result, the outside air OA is sucked in from the outside air inlet port 5, passes through the dehumidifying channel 35a of the dehumidifying unit 33 and the product air channel l ib of the indirect vaporizing element 11, and is supplied to the room as the supplied air SA from the inlet port 6 Is done.

[0265] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10L and the second exhaust passage 10M. As a result, a part of the outside air OA passes through the working air passage 11a of the indirect vaporization element 11 by the first exhaust passage 10L, and is discharged to the outside from the exhaust outlet 8 as exhaust EA. Also, the return air RA from the room is sucked in from the return air inlet 7 by the second exhaust passage 10M, passes through the regeneration passage 35b of the dehumidifying unit 33, and is discharged to the outside as the exhaust EA from the exhaust outlet 8 Is done.

[0266] Therefore, in the ventilation device 1H, the outside air OA becomes the product air PA and the working air WA.

[0267] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that passed through OA did not change the humidity (absolute humidity), but the temperature Go down.

[0268] Thus, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the temperature in the room can be lowered.

Here, both the product air flow path ib and the working air flow path 1 la of the indirect vaporization element 11 are supplied with external air OA, and the external air OA is dehumidified by the dehumidifying unit 33 in the previous stage. Therefore, as explained in Fig. 7, if the input humidity of the product air PA and working air WA is low, the outlet temperature of the product air PA will drop, so the dehumidifying unit 33 is placed before the indirect evaporative cooling unit 4. Thus, by reducing the input humidity of the product air PA and the working air WA, the outlet temperature of the product air PA can be efficiently lowered and the supply air temperature can be controlled.

[0270] Note that the outside air OA that passed through the working air flow path 11a of the indirect vaporization element 11 and the return air RA that passed through the regeneration flow path 35b of the dehumidifying unit 33 become high-humidity air, and therefore exhausted from the exhaust outlet 8 Discharge as EA.

[0271] In the ventilator 1H, similar to the ventilator 1G of the seventh embodiment, the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is determined by the opening degree of the supply air flow rate adjusting dan 14. The flow rate is adjusted. Further, the flow rate of the working air WA passing through the working air flow path 1 la of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjusting damper 15.

[0272] In this way, either or both of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 are operated to adjust the flow rate of the product air PA, the flow rate of the working air WA, or the flow rate of both. As described in FIGS. 3 and 4, the outlet temperature of the product air PA in the indirect vaporization element 11mm is controlled. Thus, the supply air temperature from the supply air outlet 6 is controlled.

[0273] Furthermore, the flow rate of the product air PA can be adjusted by changing the rotation speed of the supply fan 2, and similarly, the flow volume can be controlled by changing the rotation speed of the exhaust fan 3. The flow rate of working air WA is adjustable.

[0274] Therefore, by controlling the power of the supply fan 2 and the exhaust fan 3 or the air volume of both the supply fan 2 and the exhaust fan 3, the output of the product air PA in the indirect vaporization element 11 is controlled. The inlet temperature is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0275] Further, the indirect vaporization element can be obtained by combining the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air volume of at least one of the supply air fan 2 and the exhaust fan 3. The outlet temperature of the product air PA in 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0276] The ventilation device 1H includes the dehumidifying unit 33, and the indirect evaporative cooling unit 4 uses the outside air OA dehumidified by the dehumidifying unit 33, thereby improving the cooling capacity. In addition, by using the return air RA as regeneration air in the dehumidifying unit 33, it is possible to cool and take in outside air while exhausting indoor air to the outside, and the ventilation device 1H performs cooling while performing ventilation. It will have a function.

[0277] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, a ventilation operation in which the air in the room is replaced in a predetermined time is possible.

FIG. 15 is a configuration diagram showing an example of a ventilation device II according to the ninth embodiment. The ventilator II of the ninth embodiment is a ventilator II provided with a dehumidifying unit 33, and includes an air supply flow path that bypasses the indirect evaporative cooling unit 4. Note that in the ventilator II of the ninth embodiment, the same components as those of the ventilator 1G of the seventh embodiment are denoted by the same reference numerals.

[0279] The ventilator II communicates from the outside air intake port 5 to the supply air outlet 6 through the supply air fan 2, the dehumidification channel 35a of the dehumidification unit 33, and the product air channel l ib of the indirect vaporization element 11. An air supply passage 91 is provided. The first exhaust flow path 10J and the second exhaust flow path 10K have the same configuration as the ventilation device 1G of the seventh embodiment.

[0280] Further, the ventilator II includes a bypass passage 10N that branches from the air supply passage 91 upstream of the indirect vaporization cooling unit 4 and communicates with the air supply outlet 6 by bypassing the indirect vaporization cooling unit 4 .

[0281] The bypass flow path 10N includes an air supply flow rate adjustment damper 18. By adjusting the opening of the supply air flow adjustment damper 18, the flow rate of the air flowing through the bypass flow path 10N is adjusted. This bypasses the indirect evaporative cooling unit 4 and the flow rate of air supplied to the supply air outlet 6 Is adjusted.

Note that the air supply passage 91 includes the air purification filter 16 on the upstream side of the dehumidifying unit 33, for example.

[0283] <Operation of Ventilator II of Ninth Embodiment>

Next, the operation of the ventilator II of the ninth embodiment will be described with reference to FIG. In the ventilator II, when the air supply fan 2 is driven, a flow of directional air is generated in the air supply passage 91 to the air supply outlet 6. As a result, the outside air OA is sucked in from the outside air inlet 5 and passes through the dehumidifying passage 35a of the dehumidifying unit 33 and the product air passage 11b of the indirect vaporizing element 11 and is supplied to the room as an air supply SA from the air supply outlet 6. Is done.

[0284] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10J and the second exhaust passage 10K. As a result, the return air RA from the room is sucked in from the return air suction port 7, passes through the working air flow path 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust outlet 8 as exhaust EA. A part of the return air RA passes through the regeneration flow path 35a of the dehumidifying unit 33, and is discharged to the outside from the exhaust outlet 8 as exhaust EA.

[0285] Therefore, in the ventilator II, the outside air OA becomes the product air PA, and the return air RA becomes the boiling air WA.

[0286] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity).

[0287] Thus, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the indoor temperature can be lowered.

Here, the humidity of the outside air OA passing through the product air flow path l ib of the indirect vaporization element 11 is lowered by the dehumidifying unit 33 in the preceding stage. As a result, as described in FIG. 7, if the input humidity of the product air PA is low, the outlet temperature of the product air PA is lowered. Therefore, the dehumidifying unit 33 is arranged in front of the indirect evaporative cooling unit 4 to By reducing the input humidity of the PA, the outlet temperature of the product air PA can be efficiently lowered to control the supply air temperature. can do.

[0289] In addition, the indoor temperature can be lowered by using the ventilator II in summer. Therefore, the temperature of the return air RA is also low. As explained in Fig. 5, when the working air WA input temperature is low, the outlet temperature of the product air PA decreases. Therefore, the return air RA is used as the working air WA, so that the outlet of the product air PA can be efficiently used. It is possible to control the supply air temperature by lowering the temperature.

[0290] In the ventilator II, the bypass flow path is adjusted by adjusting the opening of the supply air flow adjustment damper 18.

The flow rate of air flowing through ION is adjusted.

[0291] Thereby, the flow rate of the air supplied to the supply air outlet 6 while bypassing the indirect vaporization cooling unit 4 is adjusted.

[0292] Therefore, the air cooled through the indirect evaporative cooling unit 4 and the indirect evaporative cooling unit 4 by adjusting the flow rate of the air flowing through the bypass flow path 10N by operating the supply air flow adjusting damper 18 and the indirect evaporative cooling unit 4 The air mixing ratio is controlled and the supply air temperature from the supply air outlet 6 is controlled.

[0293] Air that bypasses the indirect evaporative cooling unit 4 (outside air OA) is dehumidified by the dehumidifying unit 33! Therefore, the humidity of the supply air SA does not increase! /.

[0294] The ventilation device II includes the dehumidifying unit 33, and the cooling capacity is improved by using the return air RA in the indirect evaporative cooling unit 4. In addition, by using the return air RA, it is possible to cool and take in outside air while exhausting indoor air to the outside, and the ventilator II has a function of cooling while ventilating.

[0295] By adjusting the flow rate of the return air RA and the flow rate of the supply air SA, it is possible to perform a ventilation operation in which the air in the room is replaced in a predetermined time.

[0296] Configuration of Ventilator 1J of Tenth Embodiment>

FIG. 16 is a configuration diagram illustrating an example of a ventilator 1J according to the tenth embodiment. The ventilator 1J of the tenth embodiment includes a heat exchange unit 31 and a dehumidifying unit 33 in addition to the air supply fan 2, the exhaust fan 3, and the indirect evaporative cooling unit 4. In the ventilation device 1J according to the tenth embodiment, the same components as those in the ventilation device 1A according to the first embodiment are denoted by the same reference numerals. [0297] The air supply flow path 9J is supplied from the outside air inlet 5 to the air supply fan 2, the dehumidification flow path 35a of the dehumidification unit 33, the first flow path 32a of the heat exchange element 32, and the product air flow path of the indirect vaporization element 11. Go through ib and communicate with air supply outlet 6.

[0298] Note that the heat exchange unit 31 does not prescribe the order of the dehumidification unit 33 and the heat exchange unit 31 provided in the air supply passage 9 which may be upstream of the dehumidification unit 32.

[0299] The first exhaust passage 10P communicates from the return air suction port 7 to the exhaust outlet 8 through the working air passage 11a of the indirect vaporization element 11 and the exhaust fan 3. The second exhaust flow path 1 OQ passes from the return air suction port 7 to the second flow path 32b of the heat exchange element 32, the regeneration flow path 35b of the dehumidifying unit 33 and the exhaust fan 3, and the exhaust air outlet 8 To communicate.

[0300] The air supply passage 9J includes an air supply flow rate adjustment damper 14 on the upstream side of the dehumidifying unit 33, for example. By adjusting the opening degree of the supply air flow adjustment damper 14, the flow rate of the air flowing through the supply air passage 9J is adjusted. As a result, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0301] The first exhaust flow path 10P includes an exhaust flow rate adjustment damper 15 on the upstream side of the indirect evaporative cooling unit 4, for example. By adjusting the opening of the exhaust flow rate adjustment damper 15, the flow rate of the air flowing through the first exhaust flow path 10P is adjusted. As a result, the flow rate of the working air WA flowing through the shaking air flow path 11a of the indirect vaporization element 11 is adjusted.

[0302] In addition, the air supply flow path 9J includes an air purifying filter 16 on the upstream side of the dehumidifying unit 33, for example. By disposing the air purifying filter 16 on the upstream side of the dehumidifying unit 33, dust and the like are prevented from entering the dehumidifying rotor 36, the heat exchange element 32 and the indirect vaporizing element 11.

[0303] Further, the supply air flow path 9J includes a temperature sensor 17 at the supply air outlet 6 so that the supply air temperature is detected.

[0304] <Operation of Ventilator 1J of Tenth Embodiment>

Next, the operation of the ventilator 1J according to the tenth embodiment will be described with reference to FIG. When the air supply fan 2 is driven, the ventilation device 1J generates a flow of directional air to the air supply outlet 6 in the air supply passage 9J. As a result, the outside air OA is sucked in from the outside air inlet 5, and the air purification filter 16, the dehumidifying channel 35a of the dehumidifying unit 33, the first channel 32a of the heat exchange element 32, and the product air channel of the indirect vaporizing element 11 l. Pass through ib and supply air outlet Supply air from 6 as SA.

[0305] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10P and the second exhaust passage 10Q. As a result, the return air RA from the room is sucked in from the return air suction port 7, passes through the working air flow path 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust outlet 8 as exhaust EA. Further, a part of the return air RA passes through the second flow path 32b of the heat exchange element 32 and the regeneration flow path 35b of the dehumidifying unit 33, and is discharged to the outside from the exhaust outlet 8 as exhaust EA.

[0306] Therefore, in the ventilator 1J, the outside air OA becomes the product air PA, and the return air RA becomes the boiling air WA.

[0307] In the dehumidifying unit 33, the outside air OA passing through the dehumidifying channel 35a is dehumidified. However, the dehumidifying rotor

Since 36 is heated by the regeneration air heated by the heater 37 on the regeneration channel 35b side, the temperature of the outside air OA passing through the dehumidification channel 35a rises.

[0308] In the heat exchange element 32, heat exchange is performed between the outside air OA passing through the first flow path 32a and the return air RA passing through the second flow path 32b. By using the ventilator 1J in the summer, the indoor temperature is lowered, and the temperature of the return air RA is lower than the temperature of the outside air OA.

[0309] Therefore, the temperature of the outside air OA that has passed through the first flow path 32a of the heat exchange element 32 decreases, and the first

The temperature of the return air RA passing through the second flow path 32b rises.

[0310] As a result, the outside air OA dehumidified and heated by passing through the dehumidifying flow path 35a of the dehumidifying unit 33 passes through the first flow path 32a of the heat exchange element 32, so that the humidity remains unchanged. The degree goes down.

[0311] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity).

[0312] Thus, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out from the supply air outlet 6 as the supply air SA, whereby the temperature in the room can be lowered.

[0313] Here, the humidity of the outside air OA passing through the product air flow path l ib of the indirect vaporization element 11 is lowered by the dehumidifying unit 33 in the previous stage. Furthermore, the temperature is lowered by the heat exchange unit 31. It is. As a result, as described with reference to FIGS. 5 and 7, when the input humidity and input temperature of the product air PA are low, the outlet temperature of the product air PA is lowered. Therefore, the dehumidifying unit 33 and the heat are placed in front of the indirect evaporative cooling unit 4. By arranging the replacement unit 31 and lowering the input humidity and input temperature of the product air PA, the outlet temperature of the product air PA can be lowered efficiently and the supply air temperature can be controlled.

[0314] Moreover, the indoor temperature can be lowered by using the ventilator 1J in summer. Therefore, the temperature of the return air RA is also low. As explained in Fig. 5, when the working air WA input temperature is low, the outlet temperature of the product air PA decreases. Therefore, the return air RA is used as the working air WA, so that the outlet of the product air PA can be efficiently used. It is possible to control the supply air temperature by lowering the temperature.

[0315] The return air RA through the working air flow path 11a of the indirect vaporization element 11 and the return air RA through the second flow path 32b of the heat exchange element 32 and the regeneration flow path 35b of the dehumidifying unit 33 are Since it is highly humid air, it is discharged from the exhaust outlet 8 as exhaust EA.

[0316] In the ventilator 1J, the flow rate of the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Further, the flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjustment damper 15.

[0317] With this, even in the ventilator 1J equipped with the dehumidifying unit 33 and the heat exchange unit 31, either the supply air flow rate adjustment damper 14 or the exhaust flow rate adjustment damper 15 is operated, and the flow rate of the product air PA or the working air By adjusting the flow rate of WA, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled as described in FIG. 3 and FIG. Therefore, the supply air temperature from the supply air outlet 6 is controlled.

[0318] For example, when the flow rate of the working air WA is increased, the outlet temperature of the product air PA in the indirect vaporization element 11 is lowered, so that the supply air temperature from the supply air outlet 6 can be lowered.

[0319] In addition, when the flow rate of the working air WA is decreased, the outlet temperature of the outlet duct air PA in the indirect vaporization element 11 increases, so that the supply air temperature from the supply air outlet 6 can be increased. . [0320] The supply air temperature can be controlled by adjusting the flow rate of either the product air PA or the working air WA. Therefore, either the supply air flow adjustment damper 14 or the exhaust flow adjustment damper 15 is provided. Configuration is also good! ,.

[0321] In addition, by operating both the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 to adjust the flow rate of the product air PA and the flow rate of the working air WA, the product air PA in the indirect vaporization element 11 is adjusted. The outlet temperature is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0322] Furthermore, the flow rate of the product air PA can be adjusted by changing the rotation speed of the air supply fan 2, and similarly, the flow volume can be controlled by changing the rotation speed of the exhaust fan 3. The flow rate of working air WA is adjustable.

[0323] Therefore, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled by controlling the power of the air supply fan 2 and the exhaust fan 3 or the air volume of both the air supply fan 2 and the exhaust fan 3. The supply air temperature from the supply air outlet 6 is controlled.

[0324] The indirect vaporization element can be obtained by combining the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air volume of at least one of the supply air fan 2 and the exhaust fan 3. The outlet temperature of the product air PA in 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0325] The ventilator 1J includes a dehumidifying unit 33 and a heat exchange unit 31. Indirect evaporative cooling of the outside air OA dehumidified by the dehumidifying unit 33 and cooled by the heat exchange unit 4 and the cooled return air RA in the room Cooling capacity is improved by using unit 4. In addition, by using the return air RA, it is possible to cool and take in the outside air while exhausting the indoor air to the outdoors, and the ventilation device 1J has a function of cooling while performing ventilation.

[0326] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, a ventilation operation that replaces the air in the room in a predetermined time is possible.

[0327] <Configuration of ventilation device 1K of the eleventh embodiment>

FIG. 17 is a configuration diagram illustrating an example of a ventilation device 1K according to the eleventh embodiment. The ventilation device 1K of the eleventh embodiment is the same as that of the indirect vaporization element 11 constituting the indirect vaporization cooling unit 4 in the ventilation device 1K including the dehumidifying unit 33 and the heat exchange unit 31. Ngaea WA uses outside air OA. In the ventilation device 1K according to the eleventh embodiment, the same components as those in the ventilation device 1J according to the tenth embodiment will be described with the same reference numerals.

[0329] Further, the ventilation device 1K branches off from the heat exchange unit 31 to the supply air flow path 9K, and communicates with the exhaust air outlet 8 through the working air flow path 11a of the indirect vaporization element 11 and the exhaust fan 3. The first exhaust flow path 10R and the return air inlet 7 communicated with the second flow path 32b of the heat exchange element 32, the regeneration flow path 35b of the dehumidifying unit 33, and the exhaust fan 3 to the exhaust outlet 8. A second exhaust channel 10S is provided.

[0330] The air supply flow path 9K includes an air supply flow rate adjustment damper 14 on the upstream side of the dehumidifying unit 33, for example. The first exhaust flow path 10R includes an exhaust flow rate adjustment damper 15 on the downstream side of the branch position with the air supply flow path 9K, for example, on the upstream side of the indirect vaporization cooling unit 4.

[0331] By adjusting the opening of the supply air flow adjustment damper 14, the flow rate of the air flowing through the supply air passage 9K is adjusted. As a result, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0332] Further, by adjusting the opening of the exhaust flow rate adjustment damper 15, the flow rate of the air flowing through the first exhaust flow channel 10R is adjusted. As a result, the flow rate of the working air WA flowing through the working air flow path 1 la of the indirect vaporization element 11 is adjusted.

Note that the air supply passage 9K includes an air purifying filter 16 on the upstream side of the dehumidifying unit 33, for example. Further, the air supply passage 9K includes a temperature sensor 17 at the air supply outlet 6.

[0334] Operation of the ventilation device 1K of the eleventh embodiment>

Next, the operation of the ventilation device 1K according to the eleventh embodiment will be described with reference to FIG. When the air supply fan 2 is driven, the ventilation device 1K generates a flow of directional air to the air supply outlet 6 in the air supply passage 9K. As a result, the outside air OA is sucked from the outside air inlet 5 and passes through the dehumidifying channel 35a of the dehumidifying unit 33, the first channel 32a of the heat exchange element 32, and the product air channel l ib of the indirect aeration element 11. , Supply air SA from the supply air outlet 6 To be supplied indoors.

[0335] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10R and the second exhaust passage 10S. As a result, a part of the outside air OA passes through the working air flow path 1 la of the indirect vaporization element 11 by the first exhaust flow path 10R, and is discharged to the outside from the exhaust air outlet 8 as the exhaust air EA. Further, the return air RA from the room is sucked from the return air inlet 7 by the second exhaust passage 10 S and passes through the second passage 32 b of the heat exchange element 32 and the regeneration passage 35 b of the dehumidifying unit 33. From the exhaust outlet 8, it is discharged to the outside as exhaust EA.

[0336] Therefore, in the ventilation device 1K, the outside air OA becomes the product air PA and the working air WA.

[0337] In the dehumidifying unit 33, the outside air OA passing through the dehumidifying channel 35a is dehumidified. However, the dehumidifying rotor

[0338] In the heat exchange element 32, heat exchange is performed between the outside air OA passing through the first flow path 32a and the return air RA passing through the second flow path 32b. By using the ventilation device 1K in the summer, the indoor temperature is lowered, and the temperature of the return air RA is lower than the temperature of the outside air OA.

[0339] Therefore, the temperature of the outside air OA that has passed through the first flow path 32a of the heat exchange element 32 decreases, and the first

[0340] Thus, the outside air OA dehumidified and heated by passing through the dehumidifying channel 35a of the dehumidifying unit 33 passes through the first channel 32a of the heat exchange element 32, so that the humidity does not change and is heated. The degree goes down.

[0341] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity).

[0342] Accordingly, the outside temperature OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the indoor temperature can be lowered.

[0343] Here, the product air flow path l ib and the working air flow path 1 of the indirect vaporization element 11 Both the outside air OA is supplied to la, and the humidity and temperature of the outside air OA are lowered by the dehumidifying unit 33 and the heat exchange unit 31 in the previous stage. As a result, as described with reference to FIGS. 5 and 7, the input humidity and input temperature of the product air PA and the working air WA are low! And the outlet temperature of the product air PA is lowered. The dehumidification unit 33 and the heat exchange unit 31 are arranged in the air outlet, and the product air PA and working air WA input humidity and input temperature are lowered to effectively reduce the product air PA outlet temperature and supply air. The temperature can be controlled.

[0344] Note that the outside air OA passing through the working air flow path 11a of the indirect vaporization element 11 and the return air RA passing through the second flow path 32b of the heat exchange element 32 and the regeneration flow path 35b of the dehumidifying unit 33 are high. Since it is humid air, it is discharged as exhaust EA from the exhaust outlet 8.

[0345] In the ventilator 1K, similar to the ventilator 1J of the tenth embodiment, the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is determined according to the opening of the supply air flow rate adjusting dan 14. The flow rate is adjusted. Further, the flow rate of the working air WA passing through the working air flow path 1 la of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjusting damper 15.

[0346] In this way, either or both of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 are operated to adjust the flow rate of the product air PA, the flow rate of the working air WA, or the flow rate of both. As described in FIGS. 3 and 4, the outlet temperature of the product air PA in the indirect vaporization element 11mm is controlled. Thus, the supply air temperature from the supply air outlet 6 is controlled.

[0347] Furthermore, the flow rate of the product air PA can be adjusted by changing the rotation speed of the supply fan 2, and similarly, the flow volume can be controlled by changing the rotation speed of the exhaust fan 3. The flow rate of working air WA is adjustable.

[0348] Therefore, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled by controlling the power of the supply fan 2 and the exhaust fan 3 or the air volume of both the supply fan 2 and the exhaust fan 3. The supply air temperature from the supply air outlet 6 is controlled.

[0349] Further, the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air volume of at least one of the supply air fan 2 and the exhaust fan 3 may be combined. The outlet temperature of the product air PA in the indirect vaporization element 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

[0350] The ventilation device 1K includes a dehumidifying unit 33 and a heat exchanging unit 31, and uses the outside air OA dehumidified by the dehumidifying unit 33 and cooled by the heat exchanging unit 4 to cool it by using the indirect evaporative cooling unit 4. Ability improves. In addition, by using the return air RA in the dehumidifying unit 33 and the heat exchange unit 31, the outside air can be cooled and taken in while the indoor air is exhausted to the outside, and the ventilation device 1K provides cooling while ventilating. Will have the function to do.

[0351] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, a ventilation operation that replaces the air in the room in a predetermined time is possible.

[0352] <Configuration of ventilation device 1L of the twelfth embodiment>

FIG. 18 is a configuration diagram illustrating an example of a ventilation device 1L according to the twelfth embodiment. The ventilation device 1L of the twelfth embodiment is provided with an air supply flow path that bypasses the indirect evaporative cooling unit 4 in the ventilation device 1L including the dehumidifying unit 33 and the heat exchange unit 31. Note that in the ventilation device 1L according to the twelfth embodiment, the same components as those in the ventilation device 1J according to the tenth embodiment are denoted by the same reference numerals.

[0353] The ventilator 1L is connected to the outside air suction port 5 through the air supply fan 2, the dehumidification flow path 35a of the dehumidification unit 33, the first flow path 32a of the heat exchange element 32, and the product air flow path of the indirect vaporization element 11. And an air supply passage 9L that communicates with the air supply outlet 6. The first exhaust flow path 10P and the second exhaust flow path 10Q have the same configuration as the ventilator 1J of the tenth embodiment.

[0354] In addition, the ventilator 1L includes a bypass flow path 10T that branches from the air supply flow path 9L upstream of the indirect evaporative cooling unit 4 and communicates with the air supply outlet 6 by bypassing the indirect evaporative cooling unit 4 .

[0355] The bypass flow path 10T includes an air supply flow rate adjustment damper 18. By adjusting the opening of the supply air flow adjustment damper 18, the flow rate of the air flowing through the bypass flow path 10T is adjusted. As a result, the flow rate of the air supplied to the supply air outlet 6 by bypassing the indirect evaporative cooling unit 4 is adjusted.

[0356] Note that the air supply passage 9L includes an air purifying filter 16 on the upstream side of the dehumidifying unit 33, for example. [0357] Operation of Ventilator 1L of Embodiment 12>

Next, the operation of the ventilation device 1L of the twelfth embodiment will be described with reference to FIG. When the air supply fan 2 is driven, the ventilation device 1L generates a flow of directional air to the air supply outlet 6 in the air supply passage 9L. As a result, the outside air OA is sucked from the outside air inlet 5 and passes through the dehumidifying channel 35a of the dehumidifying unit 33, the first channel 32a of the heat exchange element 32, and the product air channel l ib of the indirect aeration element 11. Then, the air is supplied into the room from the air supply outlet 6 as the air supply SA.

[0358] When the exhaust fan 3 is driven, an air flow directed toward the exhaust outlet 8 is generated in the first exhaust passage 10P and the second exhaust passage 10Q. As a result, the return air RA from the room is sucked in from the return air suction port 7, passes through the working air flow path 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust outlet 8 as exhaust EA. Further, a part of the return air RA passes through the second flow path 32b of the heat exchange element 32 and the regeneration flow path 35a of the dehumidifying unit 33, and is discharged to the outdoors from the exhaust outlet 8 as exhaust EA.

[0359] Therefore, in the ventilator 1L, the outside air OA becomes the product air PA, and the return air RA becomes the boiling air WA.

[0360] In the dehumidifying unit 33, the outside air OA passing through the dehumidifying channel 35a is dehumidified. However, the dehumidifying rotor

[0361] In the heat exchange element 32, heat exchange is performed between the outside air OA passing through the first flow path 32a and the return air RA passing through the second flow path 32b. By using a ventilator 1L in the summer, the indoor temperature is lowered, and the temperature of the return air RA is lower than the temperature of the outside air OA.

[0362] Thus, the temperature of the outside air OA that has passed through the first flow path 32a of the heat exchange element 32 decreases, and the first

[0363] Thus, the outside air OA dehumidified and heated by passing through the dehumidifying channel 35a of the dehumidifying unit 33 passes through the first channel 32a of the heat exchange element 32, so that the humidity does not change and is heated. The degree goes down.

[0364] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. Product air flow path l The outside air OA that passes through the ib, the humidity (absolute humidity) does not change and the temperature drops.

[0365] Thus, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out from the supply air outlet 6 as the supply air SA, whereby the indoor temperature can be lowered.

Here, the humidity and temperature of the outside air OA passing through the product air flow path l ib of the indirect vaporization element 11 are lowered by the dehumidifying unit 33 and the heat exchange unit 31 in the preceding stage. From this, as explained in FIGS. 5 and 7, if the input humidity and input temperature of the product air PA are low, the outlet temperature of the product air PA is lowered. Therefore, the dehumidifying unit 33 is placed before the indirect evaporative cooling unit 4. In addition, by arranging the heat exchange unit 31 and lowering the input humidity and the input temperature of the product air PA, the outlet temperature of the product air PA can be efficiently lowered and the supply air temperature can be controlled.

[0367] In addition, the indoor temperature can be lowered by using the ventilator 1L in summer. Therefore, the temperature of the return air RA is also low. As explained in Fig. 5, when the working air WA input temperature is low, the outlet temperature of the product air PA decreases. Therefore, the return air RA is used as the working air WA, so that the outlet of the product air PA can be efficiently used. It is possible to control the supply air temperature by lowering the temperature.

[0368] In the ventilator 1L, by adjusting the opening of the supply air flow adjustment damper 18, the bypass flow path

The flow rate of air flowing through 10T is adjusted.

As a result, the flow rate of the air supplied to the supply air outlet 6 while bypassing the indirect vaporization cooling unit 4 is adjusted.

[0370] Therefore, the air cooled through the indirect evaporative cooling unit 4 and the indirect evaporative cooling unit 4 by adjusting the flow rate of the air flowing through the bypass flow path 10T by operating the supply air flow adjusting damper 18 and the indirect evaporative cooling unit 4 The mixing ratio of the air that is not cooled is controlled by bypassing the air supply, and the supply air temperature from the supply air outlet 6 is controlled.

[0371] Note that the air bypassing the indirect vaporization cooling unit 4 (outside air OA) is dehumidified by the dehumidification unit 33 and cooled by the heat exchange unit 31, so the humidity of the supply air SA does not increase.

[0372] The ventilator 1L includes a dehumidifying unit 33 and a heat exchange unit 31, and the dehumidifying unit 33 dehumidifies it. The indirect evaporative cooling unit 4 uses the outside air OA cooled by the heat exchange unit 4 and the indoor cooled return air RA to improve the cooling capacity. In addition, by using the return air RA, it is possible to cool and take in the outside air while exhausting the indoor air to the outdoors, and the ventilation device 1L has a function of performing cooling while performing ventilation.

[0373] Then, by adjusting the flow rate of the return air RA and the flow rate of the supply air SA, a ventilation operation in which the air in the room is replaced in a predetermined time is possible.

[0374] <Variation of ventilation device of each embodiment>

In the ventilator 1 of each of the embodiments described above, the example in which the supply air flow adjustment damper 14 and the exhaust flow adjustment damper ₁₅ are arranged on the upstream side of the indirect evaporative cooling unit 4 has been described. May be placed in

[0375] Further, since a part of the return air RA is used as the circulation RA on the supply side, the return air RA may be communicated with the outside air intake port 5. As described above, the return air RA is air-conditioned and cooled in the summer. Therefore, by using a part of the return air RA as the supply air, V, product air PA, etc. Cooling capacity is improved by lowering input temperature and input humidity.

[0376] Furthermore, in addition to the air purification filter 16, an ion generator or an ozone generator may be provided as an air purification device. For example, the ion generator generates positive ions and negative ions, has a function of supplying approximately the same number of positive ions and negative ions, and supplying only negative ions or more negative ions than positive ions.

[0377] When such an ion generator is provided at the supply air outlet 6, the supply air SA containing approximately the same number of positive ions and negative ions is supplied to the living room, etc., and sterilized by preventing generation of mold and the like. Can do. If negative ions are supplied, a relaxing effect can be obtained.

[0378] Further, by disposing the ion generator on the upstream side of the air supply passage 9 such as the upstream side of the indirect vaporization unit 4, it is possible to perform sterilization in the apparatus that is performed only in the living room.

[0379] Furthermore, the indirect evaporative cooling unit 4, the air supply fan 2, the exhaust fan 3, the heat exchange unit 31, and the dehumidifying unit ₃₃ may not be in the same casing. You may also use it.

[0380] <Variation of ventilation device with heat exchange unit> In the ventilators of the fourth to sixth embodiments described above and the ventilators of the tenth to twelfth embodiments, the heat exchange element 32 that performs sensible heat (temperature) exchange is provided as the heat exchange unit 31. However, it is also possible to have a configuration with a total heat exchange element that performs latent heat (humidity) exchange in addition to sensible heat exchange.

[0381] When performing total heat exchange between outside air OA and return air RA, the temperature and humidity of the return air RA are lower than the temperature and humidity of the outside air OA in the summer. Ki RA rises in temperature and humidity.

[0382] As in the ventilator 1D of the fourth embodiment and the ventilator 1J of the tenth embodiment, the outside air OA cooled by the heat exchange unit 31 is used as the product air PA of the indirect vaporization element 11. In the configuration, by using the total heat exchange element, the input temperature and input humidity of the product air PA can be lowered, and the outlet temperature of the product air PA can be efficiently lowered to control the temperature of the supply air SA. And the cooling capacity is improved.

[0383] Further, like the ventilator 1E of the fifth embodiment and the ventilator 1K of the eleventh embodiment, the outside air OA cooled by the heat exchange unit 31 is converted into the product air PA of the indirect vaporization element 11 and In the configuration used as the working air WA, by using the total heat exchange element, the input temperature and the input humidity of both the product air PA and the working air WA can be lowered, and the outlet temperature of the product air PA is more efficiently achieved. The temperature of the supply air SA can be controlled by lowering the temperature and the cooling capacity is improved.

[0384] <Variation of ventilation device with dehumidifying unit>

In the ventilator including the dehumidifying unit 33 described in the seventh to twelfth embodiments, the humidity of the air passing through the dehumidifying unit 33 can be controlled by controlling the rotational speed of the dehumidifying rotor 36.

FIG. 19 is a graph showing the relationship between the rotational speed of the dehumidifying rotor 36 and the outlet temperature of the product air PA. As shown in FIG. 19, it can be seen that the amount of dehumidification increases as the rotational speed of the dehumidification rotor 36 increases. Thereby, the humidity of the air output from the dehumidifying unit 33 is controlled by changing the rotational speed of the dehumidifying rotor 36.

[0386] As described in FIG. 7, in the heat exchange element 11, when the input humidity of the product air PA and the cooking air WA is lowered, the outlet temperature of the product air PA is lowered. [0387] Like the ventilation device 1G of the seventh embodiment and the ventilation device 1J of the tenth embodiment, the outside air OA dehumidified by the dehumidifying unit 33 is used as the product air PA of the indirect vaporization element 11. In this configuration, the input humidity of the product air PA can be controlled by providing speed control means for controlling the rotational speed of the dehumidifying rotor 36.

[0388] For example, when the rotational speed of the dehumidifying rotor 36 is increased, the input humidity of the product air PA is lowered, so that the outlet temperature of the product air PA can be lowered as described with reference to FIG. Therefore, the temperature of the supply air SA can be lowered. Also, if the rotational speed of the dehumidifying rotor 36 is decreased, the input humidity of the product air PA increases.

With this, the outlet temperature of the product air PA can be raised. Therefore, the temperature of the supply air SA can be raised.

[0389] Further, like the ventilator 1H of the eighth embodiment and the ventilator 1K of the eleventh embodiment, the external air OA dehumidified by the dehumidifying unit 33 is converted into the product air PA of the indirect vaporizing element 11 and In the configuration used as the working air WA, the input humidity of the product air PA and the working air WA can be controlled by controlling the rotation speed of the dehumidifying rotor 36.

[0390] By controlling the input humidity of both product air PA and working air WA, the outlet temperature of product air can be controlled more efficiently.

[0391] The control of the supply air temperature by the rotation control of the dehumidification rotor 36 may be combined with the control of the supply air temperature by the flow control by a damper or the like.

[0392] Further, a dehumidification control means for controlling the dehumidification amount of the dehumidification rotor 36 by adjusting the temperature of the regeneration heater 37 of the dehumidification rotor 36 is provided so as to control the humidity of the air supplied to the indirect evaporative cooling unit 4. Anyway.

[0393] <Other variations of ventilation system>

FIG. 20 is a configuration diagram showing an example of a ventilation device 1M according to the thirteenth embodiment. Where

In the ventilator 1M of the thirteenth embodiment, the same components as those in the ventilator 1A of the first embodiment will be described with the same numbers.

[0394] The ventilation device 1M includes an air supply fan 2 and an indirect vaporization cooling unit 4, and is a product of the indirect vaporization element 11 that constitutes the air supply fan 2 and the indirect vaporization cooling unit 4 from the outside air intake port 5. An air supply passage 9M that passes through the tato air passage l ib and communicates with the air supply outlet 6 is provided.

[0395] Further, the ventilation device 1M branches from the supply air flow path 9M downstream of the supply air fan 2, passes through the working air flow path 11a of the indirect vaporization element 11, and communicates with the exhaust air outlet 8. U is provided.

[0396] The supply air flow path 9M includes a supply air flow rate adjustment damper 14 on the downstream side of the branch position with the exhaust flow path 10U, for example, on the upstream side of the indirect evaporative cooling unit 4. Further, the exhaust flow path 10U includes an exhaust flow rate adjusting damper 15 on the downstream side of the branch position with the supply flow path 9M, for example, on the upstream side of the indirect evaporative cooling unit 4.

[0397] By adjusting the opening degree of the supply air flow adjustment damper 14, the flow rate of the air flowing through the supply air passage 9M is adjusted. As a result, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0398] Further, by adjusting the opening of the exhaust flow rate adjustment damper 15, the flow rate of the air flowing through the exhaust flow path 10U is adjusted. As a result, the flow rate of the working air WA flowing through the working air flow path 11a of the indirect vaporization element 11 is adjusted.

Next, the operation of the ventilation device 1M according to the thirteenth embodiment will be described. In the ventilator 1M, when the air supply fan 2 is driven, a flow of exhaust air to the air supply outlet 6 is generated in the air supply passage 9M. As a result, the outside air OA is sucked in from the outside air inlet 5, passes through the product air flow path l ib of the indirect vaporization element 11, and is supplied indoors as the inlet air SA from the air supply outlet 6.

[0400] Further, when the air supply fan 2 is driven, an air flow directed toward the exhaust outlet 8 is generated in the exhaust flow path 10U where the air supply flow path 9M force is also branched. As a result, a part of the outside air OA passes through the working air flow path 11a of the indirect vaporization element 11, and is discharged to the outside from the exhaust outlet 8 as exhaust EA.

[0401] Therefore, in the ventilation device 1M, the outside air OA becomes the product air PA and the working air WA.

[0402] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. Outside air that has passed through OA, the humidity (absolute humidity) remains unchanged Go down.

[0403] Accordingly, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out from the supply air outlet 6 as the supply air SA, whereby the temperature in the room can be lowered.

[0404] In the ventilator 1M, the flow rate of the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 1 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Further, the flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjustment damper 15.

[0405] In this way, either or both of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 are operated to adjust the flow rate of the product air PA, the flow rate of the working air WA, or the flow rate of both. As described in FIGS. 3 and 4, the outlet temperature of the product air PA in the indirect vaporization element 11mm is controlled. Thus, the supply air temperature from the supply air outlet 6 is controlled.

Furthermore, the flow rates of the product air PA and the working air WA can also be adjusted by changing the rotation speed of the air supply fan 2 to control the air volume.

[0407] Therefore, the combination of the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air volume of the supply air fan 2, the product air PA of the indirect vaporization element 11 is controlled. The outlet temperature is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

FIG. 21 is a configuration diagram showing an example of a ventilation device 1N according to the fourteenth embodiment. Where

In the ventilator 1N of the 14th embodiment, the same components as those in the ventilator 1A of the first embodiment will be described with the same numbers.

[0409] The ventilator 1N includes an exhaust fan 3 and an indirect vaporization cooling unit 4, and passes through the product air flow path l ib of the indirect vaporization element 11 constituting the indirect vaporization cooling unit 4 from the return air suction port 7 to supply air. An air supply passage 9N communicating with the outlet 6 is provided.

[0410] Further, the ventilation device 1N includes an exhaust passage 10V that communicates from the return air suction port 7 through the working air passage 11a of the indirect vaporization element 11 and the exhaust fan 3 to the exhaust outlet 8.

[0411] The air supply flow path 9N is provided, for example, on the upstream side of the indirect evaporative cooling unit 4 with an air supply flow rate adjusting damper 1

With four. The exhaust flow path 10V is exhausted upstream of the indirect evaporative cooling unit 4, for example. A flow control damper 15 is provided.

[0412] By adjusting the opening of supply air flow adjustment damper 14, the flow rate of air flowing through supply air passage 9N is adjusted. As a result, the flow rate of the product air PA flowing through the product air flow path l ib of the indirect vaporization element 11 is adjusted.

[0413] Further, by adjusting the opening of the exhaust flow rate adjusting damper 15, the flow rate of the air flowing through the exhaust flow path 10V is adjusted. As a result, the flow rate of the working air WA flowing through the working air flow path 11a of the indirect vaporization element 11 is adjusted.

[0414] In the ventilation device 1N, the air supply device 41 or the like is connected to the air supply outlet 6 via a duct or the like (not shown). The air supply device 41 is, for example, a device that sucks outside air or room air and supplies the air into the room. The air supply outlet 6 of the ventilation device 1N is connected to the suction port 41a of the air supply device 41.

[0415] Next, the operation of the ventilation device 1N of the fourteenth embodiment will be described. In the ventilation device 1N, when the air supply device 41 is driven, an air flow directed toward the air supply outlet 6 is generated in the air supply passage 9N. As a result, the return air RA is sucked in from the return air intake port 7, passes through the product air flow path l ib of the indirect vaporization element 11, and is supplied indoors as the supply air SA from the supply air outlet 6 through the air supply device 41. Is done.

[0416] Further, when the exhaust fan 3 is driven, a flow of directional force to the exhaust outlet 8 is generated in the exhaust passage 10V. As a result, the return air RA passes through the working channel 11a of the indirect vaporization element 11, and is discharged to the outside from the exhaust outlet 8 as exhaust EA.

[0417] Therefore, in the ventilation device 1N, the return air RA becomes the product air PA and the working air WA.

[0418] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The return air RA that has passed through has the humidity (absolute humidity) unchanged and the temperature drops.

[0419] Accordingly, the return air RA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out from the supply air outlet 6 as the supply air SA, whereby the temperature in the room can be lowered.

[0420] In the ventilation device 1N, the flow rate of the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Also exhaust The flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the flow rate adjusting damper 15.

[0421] In this way, either or both of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 are operated to adjust the flow rate of the product air PA, the flow rate of the working air WA, or the flow rate of both. As described in FIGS. 3 and 4, the outlet temperature of the product air PA in the indirect vaporization element 11mm is controlled. Thus, the supply air temperature from the supply air outlet 6 is controlled.

[0422] Furthermore, the working air W can be controlled by changing the rotation speed of the exhaust fan 3 to control the air flow.

The flow rate of A can be adjusted.

[0423] Therefore, the outlet of the product air PA in the indirect vaporization element 11 is combined with the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air flow of the exhaust fan 3. The temperature is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

FIG. 22 is a configuration diagram showing an example of a ventilation device 1P according to the fifteenth embodiment. Here, in the ventilator 1P of the fifteenth embodiment, the same components as those of the ventilator 1D of the fourth embodiment will be described with the same numbers.

[0425] The ventilator 1P includes the heat exchange unit 31 and the indirect evaporative cooling unit 4, and the first flow path 32a of the heat exchange element 32 and the indirect evaporative cooling unit in which the outside air inlet 5 force also constitutes the heat exchange unit 31. 4 is provided with a supply air flow path 9P that passes through the product air flow path l ib of the indirect vaporization element 11 constituting 4 and communicates with the supply air outlet 6.

[0426] In addition, the ventilator 1P passes through the working air flow path 11a of the indirect vaporization element 11 from the return air suction port 7 and communicates with the exhaust outlet 8 and the first exhaust flow path 10W and the return air suction port 7 Through the second flow path 32b of the heat exchange element 32 and the second exhaust flow path 10X communicating with the exhaust outlet 8 is provided.

[0427] In the ventilation device 1P, the air supply device 41 and the like are connected to the air supply outlet 6 via a duct or the like (not shown). Further, an exhaust device 42 and the like are connected to the return air suction port 7 through a duct and the like (not shown). The exhaust device 42 is, for example, a device that sucks indoor air and exhausts it outdoors. The return air suction port 7 of the ventilator 1P is connected to the outlet 42a of the exhaust device 42. [0428] Next, the operation of the ventilation device IP of the fifteenth embodiment will be described. In the ventilation device 1P, when the air supply device 41 is driven, an air flow directed toward the air supply outlet 6 is generated in the air supply passage 9P. As a result, the outside air OA is sucked from the outside air inlet 5 and passes through the first flow path 32a of the heat exchange element 32 and the product air flow path 1 lb of the indirect vaporization element 11, and is supplied from the supply air outlet 6 to the air supply device. It is supplied indoors as supply air SA via 41.

[0429] Further, when the exhaust device 42 is driven, a flow of directed air to the exhaust outlet 8 is generated in the first exhaust passage 10W and the second exhaust passage 10X. As a result, the return air RA passes through the working air flow path 11a of the indirect vaporization element 11 via the exhaust device 42, and is discharged to the outside from the exhaust outlet 8 as exhaust EA. Further, a part of the return air RA passes through the second flow path 32b of the heat exchange element 32 via the exhaust device 42, and is discharged outside as an exhaust EA from the exhaust outlet 8.

[0430] Therefore, in the ventilation device 1P, the outside air OA becomes the product air PA, and the return air RA becomes the boiling air WA.

[0431] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. Outside air that has passed through OA, the humidity (absolute humidity) does not change and the temperature drops.

[0432] Therefore, the outside temperature OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the indoor temperature can be lowered.

[0433] In the ventilation device 1P, the air supply device 41 adjusts the flow rate of the product air PA that passes through the product air flow path l ib of the indirect vaporization element 11. The exhaust device 42 adjusts the flow rate of the working air WA that passes through the working air flow path 1 la of the indirect vaporization element 11.

Thus, by controlling the flow rate in one or both of the air supply device 41 and the exhaust device 42, the outlet temperature of the product air PA in the indirect vaporization element 11 as described in FIG. 3 and FIG. Is controlled. Therefore, the supply air temperature from the supply air outlet 6 is controlled.

[0435] As stated above, the building standards require the building to be ventilated, so that a single unit can supply and exhaust air (referred to as a 24-hour ventilator), exhaust only, or A ventilation system (called an intermediate duct fan) that can only supply air is installed in the building. By connecting with such other ventilators, a configuration with only the exhaust fan 3 as a fan, such as the ventilator 1N, or a configuration with neither an air supply fan nor an exhaust fan, like the ventilator 1P The product cost can be reduced by not installing a fan.

[0436] <Configuration example of ventilator reusing working air>

FIG. 23 is a configuration diagram showing an example of a ventilation device 1Q according to the sixteenth embodiment. The ventilation device 1Q exhausts the working air WA of the indirect vaporization element 11 constituting the indirect vaporization cooling unit 4 through the heat exchange unit 31. The overall configuration of the ventilator will be described by taking the ventilator 1D of the fourth embodiment as an example.

[0437] Ventilator 1Q is equipped with air supply fan 2, exhaust fan 3, heat exchange unit 31, and indirect evaporative cooling unit 4, and uses outside air OA as product air PA of indirect evaporating element 11, and returns RA Is used as working air WA.

The supply air flow path 9D communicates from the supply air fan 2 through the first flow path 32a of the heat exchange element 32 and the product air flow path l ib of the indirect vaporization element 11 to the supply air outlet 6.

[0439] The ventilation flow path 10Y passes from the return air suction port 7 to the working air flow path 1 la of the indirect vaporization element 11, the second flow path 32b of the heat exchange element 32 and the exhaust fan 3 to the exhaust air outlet 8. Communicate. The portion indicated by the broken line of the exhaust passage 10Y is formed along the side wall of the case, for example, so as to be independent of the air supply passage 9D and the like.

[0440] The supply air flow path 9D includes, for example, a supply air flow adjustment damper 14 on the upstream side of the heat exchange unit 31, and adjusts the opening degree of the supply air flow adjustment damper 14 to adjust the product air of the indirect vaporization element 11. Flow rate of product air PA flowing through flow path l ib is adjusted.

[0441] The exhaust flow path 10Y includes, for example, an exhaust flow rate adjustment damper 15 on the upstream side of the indirect vaporization cooling unit 4, and the working air flow path of the indirect vaporization element 11 is adjusted by adjusting the opening degree of the exhaust flow rate adjustment damper 15. The flow rate of working air WA flowing through 11a is adjusted.

[0442] Next, the operation of the ventilator 1Q will be described. In the ventilation device 1Q, when the air supply fan 2 is driven, an air flow directed toward the air supply outlet 6 is generated in the air supply passage 9D. As a result, outside air OA is sucked from the outside air inlet 5, and the air purification filter 16, heat exchange The air passes through the first flow path 32a of the element 32 and the product air flow path l ib of the indirect vaporization element 11, and is supplied into the room as the supply air SA from the supply air outlet 6.

[0443] Further, when the exhaust fan 3 is driven, a flow of directional force to the exhaust outlet 8 is generated in the exhaust passage 10Y. As a result, the return air RA having the indoor force is sucked from the return air inlet 7 and passes through the working air passage 11a of the indirect vaporization element 11 and the second passage 32b of the heat exchange element 32, and then from the exhaust outlet 8. Exhaust is discharged outdoors as EA.

[0444] Therefore, in the ventilation device 1Q, the outside air OA becomes the product air PA and the return air RA becomes the burning air WA.

[0445] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity). In addition, the return air RA passing through the working air channel 11a increases in humidity but decreases in temperature.

[0446] Thus, the outside temperature OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the indoor temperature can be lowered.

[0447] In the heat exchange element 32, heat is exchanged between the outside air OA passing through the first flow path 32a and the return air RA passing through the second flow path 32b. The return air RA is lowered in temperature by passing through the working channel 11a of the indirect vaporization element 11, and is lower than the temperature of the outside air OA.

[0448] Therefore, the temperature of the outside air OA that has passed through the first flow path 32a of the heat exchange element 32 decreases. Here, the return air RA is a force that increases the humidity by passing through the working air flow path 11a of the indirect vaporization element 11. Since the heat exchange element 32 is a heat exchange element that exchanges sensible heat, the humidity of the outside air OA is It will not change!

[0449] As a result, the return air RA that has passed through the working air flow path 11a of the indirect vaporization element 11 passes through the second flow path 32b of the heat exchange element 32, so that the outside air OA is removed in the front stage of the indirect vaporization cooling unit 4. It can be cooled efficiently.

[0450] As explained in Fig. 5, when the input temperature of the product air PA is low, the outlet temperature of the product air PA is lowered. Therefore, the heat exchange unit 31 is arranged in the front stage of the indirect evaporative cooling unit 4, and the working air By passing WA through heat exchange unit 31, product air PA This effectively lowers the input temperature and improves the cooling capacity.

[0451] In the ventilator 1Q, the flow rate of the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Further, the flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjustment damper 15.

[0452] Thus, if one or both of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 are operated, for example, when the flow rate of the working air WA is increased, the product air PA in the indirect vaporization element 11 is increased. As a result, the supply air temperature from the supply air outlet 6 can be lowered.

[0453] Further, when the flow rate of the working air WA is decreased, the outlet temperature of the outlet duct air PA in the indirect vaporization element 11 is increased, so that the supply air temperature from the supply air outlet 6 can be increased. .

[0454] In addition, the outlet temperature of the product air PA in the indirect vaporization element 11 is controlled by controlling the air volume of either the supply fan 2 and the exhaust fan 3, or both the supply fan 2 and the exhaust fan 3. The supply air temperature from the supply air outlet 6 is controlled.

[0455] Further, the indirect vaporization element can be obtained by combining the control of the opening degree of at least one of the supply air flow adjustment damper 14 and the exhaust flow adjustment damper 15 and the control of the air volume of at least one of the supply air fan 2 and the exhaust fan 3. The outlet temperature of the product air PA in 11 is controlled, and the supply air temperature from the supply air outlet 6 is controlled.

FIG. 24 is a configuration diagram showing an example of a ventilation device 1R according to the seventeenth embodiment. The ventilator 1R uses the working air WA of the indirect vaporization element 11 constituting the indirect vaporization cooling unit 4 as the supply air SA. The overall configuration of the ventilator will be described by taking the ventilator 1E of the fifth embodiment as an example.

[0457] The ventilation device 1R includes an air supply fan 2, an exhaust fan 3, a heat exchange unit 31, and an indirect evaporative cooling element 4, and uses outside air OA as the product air PA and the working air WA of the indirect vaporization element 11. .

[0458] The first supply air flow path 9R is supplied from the outside air intake port 5 through the supply air fan 2, the first flow path 32a of the heat exchange element 32, and the product air flow path l ib of the indirect vaporization element 11. Air outlet 6 Go to.

[0459] The second air supply passage 9S branches from the first air supply passage 9R on the downstream side of the heat exchange unit 31, passes through the working air passage 11a of the indirect vaporization element 11 and the dehumidifier 44, and supplies air. Connect to outlet 6.

[0460] The exhaust flow path 10H communicates from the return air suction port 7 to the exhaust air outlet 8 through the second flow path 32b of the heat exchange element 32 and the exhaust fan 3.

[0461] The dehumidifier 44 includes a permeable membrane filter or the like to separate water and air, and dehumidifies the air passing through the second air supply passage 9S.

[0462] The first air supply flow path 9R includes, for example, an air supply flow rate adjustment damper 14 on the upstream side of the heat exchange unit 31, and the indirect vaporization element 11 is adjusted by adjusting the opening degree of the air supply flow adjustment damper 14. Product air flow path l Flow rate of product air PA flowing through ib is adjusted.

[0463] Further, the second air supply flow path 9S includes, for example, an exhaust flow rate adjustment damper ₁₅ on the upstream side of the indirect vaporization cooling unit 4, and the opening degree of the exhaust flow rate adjustment damper ₁₅ is adjusted, so that the indirect vaporization element 11 Working air flow path of Working air WA flowing through 1 la is adjusted.

[0464] Next, the operation of the ventilation device 1R according to the seventeenth embodiment will be described. In the ventilator 1R, when the air supply fan 2 is driven, an air flow directed toward the air supply outlet 6 is generated in the first air supply passage 9R and the second air supply passage 9S. As a result, the outside air OA is sucked and sucked in from the outside air inlet port 5, passes through the first channel 32 a of the heat exchange element 32 and the product air channel l ib of the indirect vaporization element 11, and is supplied from the inlet port 6. Qi is supplied indoors as SA.

[0465] In addition, a part of the outside air OA that has passed through the heat exchange unit 31 passes through the first king air flow path 11a of the indirect vaporization element 11 and the dehumidifier 44, and is supplied to the room as the supply air SA from the supply air outlet 6 Is done.

[0466] Furthermore, when the exhaust fan 3 is driven, an air flow toward the exhaust outlet 8 is generated in the exhaust passage 10H. As a result, the return air RA from the room is sucked from the return air suction port 7, passes through the second flow path 32 b of the heat exchange element 32, and is discharged to the outside as the exhaust air EA from the exhaust air outlet 8. [0467] Therefore, in the ventilation device 1R, the outside air OA becomes the product air PA and the working air WA.

[0468] In the heat exchange element 32, heat exchange is performed between the outside air OA passing through the first flow path 32a and the return air RA passing through the second flow path 32b. By using the ventilator 1R in summer, the indoor temperature is lowered, and the temperature of the return air RA is lower than the temperature of the outside air OA.

Therefore, the temperature of the outside air OA that has passed through the first flow path 32a of the heat exchange element 32 decreases, and the temperature of the return air RA that has passed through the second flow path 32b increases.

[0470] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity). In addition, the outside air OA that passes through the working air channel 11a increases in humidity but decreases in temperature.

[0471] Accordingly, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out as the supply air SA from the supply air outlet 6, whereby the temperature in the room can be lowered.

[0472] The outside air OA that has passed through the working air flow path 11a of the indirect vaporization element 11 becomes high humidity, but can be used as the supply air SA by dehumidification through the dehumidifying device 44, and the product air flow path 1 By blowing out as air supply SA from the air supply outlet 6 together with outside air OA passing through lb, the room temperature can be lowered without increasing the humidity.

[0473] Here, outside air OA is supplied to both the product air flow path l ib and the working air flow path 1 la of the indirect vaporization element 11, and the temperature of the outside air OA is lowered by the heat exchange unit 31 in the previous stage. Yes. As a result, the outlet temperature of the product air PA can be lowered efficiently and the air supply temperature can be controlled. Furthermore, the cooling capacity is improved by dehumidifying the cooled working air WA and using it as the supply air SA.

[0474] In the ventilator 1R, the flow rate of the product air PA passing through the product air flow path l ib of the indirect vaporization element 11 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Further, the flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjustment damper 15.

[0475] As a result, either the supply air flow adjustment damper 14 or the exhaust flow adjustment damper 15 or For example, if the flow rate of working air WA is increased by operating both of them, the outlet temperature of product air PA in indirect vaporization element 11 decreases, thereby lowering the supply air temperature from supply air outlet 6 Can do.

[0476] In addition, when the flow rate of the working air WA is decreased, the outlet temperature of the outlet duct air PA in the indirect vaporization element 11 increases, so that the supply air temperature from the supply air outlet 6 can be increased. .

[0477] Example of ventilation device configuration using exhaust heat in dehumidifying unit>

FIG. 25 is a block diagram showing an example of a ventilation device 1S of the eighteenth embodiment. Ventilation equipment

1S uses exhaust heat as a heat source for regeneration air. The overall configuration of the ventilator will be described by taking the ventilator 1G of the seventh embodiment as an example.

[0478] The ventilation device 1S includes a dehumidifying unit 33. The dehumidifying unit 33 includes a heater 37 that heats the air (regeneration air) passing through the regeneration flow path 35b, but uses the exhaust heat as a heat source for the heater 37.

[0479] As an exhaust heat generation source, for example, an outdoor unit 38 of an air conditioner is used. The hot air collector 38a is attached to the outdoor unit 38, and the hot air is sent to the heater 37 through the duct 39a and the like.

[0480] The heater 37 passes the warm air from the outdoor unit 38 through, for example, a pipe wound in a coil shape, and heats the regenerated air passing through the regenerative flow path 35b. The warm air passing through the heater 37 is exhausted by the exhaust device 42 through the duct 39b and the like.

[0481] The operation of the ventilator 1S is the same as that of the ventilator 1G of the seventh embodiment. A part of the return air RA is used as regeneration air. By using the exhaust heat of the outdoor unit 38 for heating the regeneration air, it is not necessary to provide the drive source of the heater 37 in the ventilator 1S. Compared with the case where an air heater is used, power consumption can be suppressed.

[0482] As the heat source of the heater 37, in addition to the exhaust heat of the outdoor unit, hot air or hot water by heat for boiling water may be used in a water heater for boiling water by gas or electricity.

[0483] <Configuration of main part of ventilator of each embodiment>

FIG. 26A and FIG. 26B are perspective views showing an example of a main configuration of the ventilator according to each embodiment. For example, as described in FIG. 10A, FIG. 10B, etc., in the ventilator of the fourth to sixth embodiments having the heat exchange unit 31 and the indirect evaporative cooling unit 4, the heat exchange unit 31 is surrounded by heat insulating material 51a, and the indirect evaporative cooling unit 4 is surrounded by 5 lb of heat insulating material.

[0484] The heat insulating material 51a and the heat insulating material 51b are made of, for example, polystyrene foam, and have a shape in which a flow path is opened, and surround the heat exchange unit 31, the indirect evaporative cooling unit 4, and the like. By enclosing the heat exchange unit 31 and the indirect evaporative cooling unit 41 with a heat insulating material, it is less affected by the temperature outside the apparatus, and the cooling capacity can be improved.

[0485] Here, by enclosing the heat exchange unit 31 and the indirect vaporization cooling unit 4 with independent heat insulating materials, it is possible to improve maintainability during unit replacement. Alternatively, each unit may be enclosed by a single heat insulating material.

[0486] In addition to the heat exchange unit 31 and the indirect evaporative cooling unit 4, the unit enclosed by the heat insulating material may be an air purifying device such as an air purifying filter disposed in a flow path through which air passes. As an air cleaning device, an ion generator, an ozone generator, etc. other than an air cleaning filter may be used.

[0487] Further, in FIGS. 26A and 26B, the ventilating apparatus according to the fourth to sixth embodiments including the heat exchange unit 31 and the indirect evaporative cooling unit 4 has been described as an example. The ventilators of the first to third embodiments, the ventilators of the seventh to ninth embodiments having the dehumidifying unit 33 and the indirect evaporative cooling unit 4, and the dehumidifying unit 33 The ventilating apparatus of the tenth to twelfth embodiments provided with the heat exchange unit 4 and the indirect evaporative cooling unit 4 can be similarly applied.

[0488] FIG. 27 is a configuration diagram of a main part of the ventilation device of each embodiment. For example, in the ventilator 1D provided with the heat exchange unit 31 and the indirect evaporative cooling unit 4 described with reference to FIGS. 10A and 10B, the supply air flow path 9D between the heat exchange unit 31 and the indirect evaporative cooling unit 4 is A diffusion plate 52 is provided. The diffusion plate 52 stirs the air passing through the air supply flow path 9D.

[0489] The air that flows into the heat exchange unit 31 and the indirect vaporization cooling unit 4 flows toward the center, and is less likely to be a uniform flow with respect to each flow path of the indirect vaporization element 11 and the like. For this reason, by providing the diffusion plate 52 in front of the indirect evaporative cooling unit 4 or the like, the air can be agitated, and the cooling capacity can be improved by making the flow substantially uniform with respect to each flow path.

[0490] The diffusion plate 52 may be provided in front of the heat exchange unit 31. Further, for example, in the ventilator 1G having the dehumidifying unit 33 and the indirect evaporative cooling unit 4 described in FIG. Ventilation according to another embodiment in which the supply plate 9G between the unit 33 and the indirect evaporative cooling unit 4 may be provided with a diffusion plate 52, and further, a diffusion plate 52 may be provided in front of the dehumidifying unit 33 Applicable to the device.

[0491] FIG. 28 is another main part configuration diagram of the ventilation device of each embodiment. For example, in the ventilator 1D having the heat exchange unit 31 and the indirect evaporative cooling unit 4 described with reference to FIGS. 10A and 10B, the heat exchange unit 31 and the indirect evaporative cooling unit 4 are arranged close to each other, and the heat exchange unit The gap between the outlet of the first flow path 32a of the heat exchange element 32 constituting 31 and the product air flow path 1 lb of the indirect vaporization element 11 constituting the indirect vaporization cooling unit 4 is as much as possible. Try to reduce it. In FIG. 28, for example, an air supply flow rate adjustment damper provided on the upstream side of the heat exchange unit 31 and an exhaust flow rate adjustment damper provided on the upstream side of the indirect evaporative cooling unit 4 are illustrated.

[0492] If the distance between the heat exchange unit 31 and the indirect evaporative cooling unit 4 is wide, the air flowing into the indirect evaporative cooling unit 4 is directed toward the center, and is uniform for each flow path of the indirect vaporization element 11. It is hard to become a flow. For this reason, the cooling capacity can be improved by arranging the heat exchange unit 31 and the indirect vaporization cooling unit 4 close to each other so as to make the flow substantially uniform with respect to each flow path.

[0493] The clearance between the heat exchange unit 31 and the indirect evaporative cooling unit 4 is preferably about 5 cm or less. Alternatively, the heat exchange element 32 and the indirect vaporization element 11 may be integrated so that the first flow path 32a of the heat exchange element 32 and the product air flow path ib of the indirect vaporization element 11 communicate with each other. ,.

[0494] Furthermore, if the area of the outlet of the first flow path 32a of the heat exchange element 32 and the inlet of the product air flow path l ib of the indirect vaporization element 11 are the same, the air flow becomes efficient. In addition, since each unit can be reduced in size, the apparatus can be reduced in size.

[0495] FIGS. 29A to 29C are other configuration diagrams of the indirect vaporization element of FIGS. 2A to 2C showing the configuration of the main parts of the ventilation device of each embodiment. 29A is an external perspective view, FIG. 29B is an exploded perspective view, and FIG. 29C is a cross-sectional view.

[0496] As shown in FIG. 29B, the indirect vaporization element 11 / includes a dry cell 21 having a plurality of first flow paths 21b partitioned by a partition 21a, and a plurality of second flow paths partitioned by a partition 22a. 2 2b, and a dry cell 21 and a partition wall 23 partitioning the wet cell 22. The entrances and exits of each flow path are formed on different surfaces, and the first flow path 21b and the second flow path 22b It is configured to be partially parallel.

[0497] As shown in FIG. 29C, the partition wall 23 includes a moisture-proof film 23a formed of a polyethylene film or the like, and a wet layer 23b formed of pulp or the like. The moisture-proof film 23a faces the dry cell 21, and the wet layer 23b faces the wet cell 22.

Thus, in the indirect vaporization element 11 /, the second flow path 22b becomes the baking air flow path 1 la shown in FIG. 1 and the like, and the second flow path 21b becomes the product air flow path 1 lb.

[0499] In the indirect evaporative cooling element 11 /, when the working air flow path 11a and part of the product air flow path 1 lb are arranged in parallel, the working air flow path 1 la and the product air flow path l ib Since the part in contact with the partition wall 23 becomes longer, the cooling heat of the mono-king air WA cooled by the heat of vaporization is efficiently transmitted to the product air PA, and the cooling capacity can be improved.

[0500] <Ventilation device installation example>

FIG. 30 is a configuration diagram showing an example of a building according to the present embodiment, and shows an installation example of the ventilation device 1. The ventilation device 1 described in FIG. 1 and the like is installed on the ceiling of the building 101 or the like.

[0509] <Configuration example of a ventilator that branches supply air>

FIG. 32 is a configuration diagram showing an example of a ventilation device 1T according to the nineteenth embodiment. The ventilator 1T is provided with a plurality of air supply outlets 6 and the flow rate can be controlled at each of the air supply outlets 6. The overall configuration of the ventilator will be described by taking the ventilator 1A of the first embodiment as an example.

[0510] The ventilator 1T includes a first air supply outlet 6a and a second air supply outlet 6b in this example as the air supply outlet. In addition, the ventilation device 1T includes an air supply fan 2, an exhaust fan 3, and an indirect evaporative cooling unit 4, and an air supply flow path 9A connects a product air flow path l ib of the indirect vaporization element 11 from the air supply fan 2. And communicates with the first air supply outlet 6a and the second air supply outlet 6b.

[0511] The ventilation channel 10A communicates from the return air suction port 7 to the exhaust air outlet 8 through the working air channel 1 la of the indirect vaporization element 11 and the exhaust fan 3.

[0512] The air supply flow path 9A includes an air supply flow rate adjustment damper 14 on the upstream side of the indirect evaporative cooling unit 4, for example. Further, the exhaust passage 10A includes an exhaust flow rate adjustment damper 15 on the upstream side of the indirect evaporative cooling unit 4, for example.

[0513] Furthermore, an air supply flow rate adjusting damper 19 is provided in at least one of the first air supply outlet 6a and the second air supply outlet 6b. In this example, an air supply flow rate adjusting damper 19 is provided at the second air supply outlet 6b. By adjusting the opening degree of the supply air flow adjustment damper 19, the flow rate of the supply air SA flowing through the second supply air outlet 6b is adjusted.

[0514] Next, the operation of the ventilator 1T will be described. In the ventilator 1T, when the air supply fan 2 is driven, a flow of directed air is generated in the air supply passage 9A to the first air supply outlet 6a and the second air supply outlet 6b. As a result, the outside air OA is sucked in from the outside air inlet 5 and passes through the product air flow path l ib of the air purification filter 16 and the indirect vaporization element 11, and then the first air supply outlet 6a and the second air supply outlet 6b. Supplied from the room as SA.

[0515] When the exhaust fan 3 is driven, a flow of directional force is generated in the exhaust passage 10B to the exhaust outlet 8. As a result, the return air RA having a strong indoor force is sucked from the return air suction port 7, passes through the working air passage 11 a of the indirect vaporization element 11, and is discharged to the outside from the exhaust air outlet 8 as the exhaust air EA. [0516] As described above, in the indirect vaporization element 11, the working air WA is cooled by the heat of vaporization of water, and the product air PA is cooled by the cold heat of the working air WA. The outside air that has passed through OA drops without changing the humidity (absolute humidity). In addition, the return air RA passing through the working air channel 11a increases in humidity but decreases in temperature.

[0517] Accordingly, the outside air OA that has passed through the product air flow path l ib of the indirect vaporization element 11 is blown out from the first supply air outlet 6a and the second supply air outlet 6b as the supply air SA, thereby The temperature can be lowered.

[0518] In the ventilator 1T, the flow rate of the product air PA passing through the product air flow path ib of the indirect vaporization element 11 is adjusted by the opening degree of the supply air flow rate adjustment damper 14. Further, the flow rate of the working air WA passing through the working air flow path 11 a of the indirect vaporization element 11 is adjusted by the opening degree of the exhaust flow rate adjustment damper 15.

[0519] Thereby, the air supply flow adjustment damper 14 and the exhaust flow adjustment damper 15 are actuated, or both of them are operated to supply air that is blown out from the first supply air outlet 6a and the second supply air outlet 6b. The SA temperature is controlled.

[0520] Furthermore, in the ventilator 1T, by operating the supply air flow rate adjusting damper 19, the flow rate of the supply air SA blown out from the first supply air outlet 6a and the supply air blown out from the second supply air outlet 6b. Qi S

The flow rate of A is controlled.

[0521] For example, the flow rate of the supply air flow adjusting damper 19 can be increased by increasing the opening degree of the supply air flow adjusting damper 19 to increase the flow rate of the supply air SA that also blows the second supply air outlet 6b. By reducing the degree, the flow rate of the supply air SA discharged from the second supply air outlet 6b can be reduced.

[0522] As shown in FIG. 30, when supplying air from the ventilator 1 to a plurality of rooms 102, the length of each duct 106 may be different because the power to the ventilator 1 is not evenly spaced from each room 102. Many.

[0523] Supply Air When each SA 102 is supplied with ducts 106 having different lengths with the same flow rate, the cooling temperature in each room 102 is different. The cooling temperature varies depending on the size of the room 102. For this reason, as shown in Fig. 32, the flow rate can be adjusted at multiple air supply outlets 6. In addition, if the air volume is controlled according to the length of the duct 106, the cooling temperature of each room 102 can be made substantially the same.

[0524] Note that in Fig. 32, the supply air outlet may have two or more forces as described in the two examples. In addition, although the flow rate is adjusted with a damper, a configuration in which the diameter of the supply air outlet 6 can be varied is also acceptable. Furthermore, the branch chamber 106a shown in FIG. 30 may have an equivalent function.

[0525] Also, as shown in Fig. 30, when the return air RA is also applied to one room (toilet), there is only one return air inlet 7 as shown in Fig. 32, but the return air RA is divided into multiple rooms. When performing from (residential room), a plurality of return air inlets 7 may be provided. In this case, providing at least one return air inlet 7 with a damper adjusts the flow rate of the return air RA and adjusts the return air flow rate for each room, for example, returning air from a certain room stops. Etc. can be controlled.

[0526] <Ventilator control example>

FIG. 33 is a block diagram showing an example of the control function of the ventilator. As an example of a ventilator, a configuration with a dehumidifying unit is used. The ventilator 1 includes a CPU 71 which constitutes the control means, a fan motor 72 which drives the air supply fan 2 and the exhaust fan 3, a damper motor 73 such as an air supply flow adjustment damper 14 and an exhaust flow adjustment damper 15, and a dehumidifier. A dehumidification rotor motor 74 that drives the dehumidification rotor 36 of the unit 33 is connected, and the CPU 71 controls these drive sources, thereby controlling the temperature of the supply air SA and the like.

[0527] Further, the water supply valve 12a and the water discharge valve 12b of the water supply / drainage device 12 are connected to the CPU 71, and the water supply / drainage control in the indirect evaporative cooling unit 4 is performed. Further, the CPU 71 is connected with a temperature sensor 17 provided at the air supply outlet 6 and the like, and a human sensor 62 and a temperature sensor 63 provided at the air supply port 105 shown in FIG. The temperature of the air supply SA is controlled.

[0528] In addition, the CPU 71 is connected with a setting switch 75 that constitutes setting means and performs various operations, a cooling operation stop switch 76, and a memory 77 that stores setting information and the like, and is based on various operations and settings. ! /, And temperature control of supply air SA, control of operation stop, etc. are performed.

[0529] When the ion generator is provided in the ventilator 1 or the like, the ion generator is connected to the CPU 71 to control the generation of positive and negative ions.

[0530] <Control by temperature sensor> FIG. 34 is a flowchart showing an example of cooling control by the temperature sensor, and a specific control example will be described with reference to FIG. 32 and the like. Here, it is assumed that a desired set temperature value is registered in the memory 77 in advance. In addition, it is assumed that the fan motor 72 and the like are driven to perform a cooling operation.

[0531] Step SA1: The CPU 71 reads the temperature of the supply air SA from the temperature sensor 17. Or, the temperature of the room 102 is read from the temperature sensor 63.

[0532] Step SA2: The CPU 71 reads the set temperature value from the memory 77.

[0533] Step SA3: The CPU 71 detects the temperature of the supply air SA read from the temperature sensor 17, for example.

Compare the set temperature value read from memory 77. If the temperature of the supply air SA is lower than the set temperature value, the current control is maintained without changing the fan speed, damper opening, etc., and the process returns to step SA1.

[0534] Step SA4: When the temperature of the supply air SA is higher than the set temperature value in the comparison with step SA3, the CPU 71 lowers the temperature of the supply air SA. For example, the indirect evaporative cooling unit shown in FIG. 4. Increase the working air WA flow rate. For example, the CPU 71 controls the damper motor 73 to increase the flow rate of the working air WA by increasing the opening degree of the exhaust flow rate adjustment damper 15.

[0535] When the flow rate of the working air WA increases in the indirect evaporative cooling unit 4, the temperature of the product air PA decreases as described above. Therefore, the temperature of the supply air SA can be lowered.

Note that the temperature control of the supply air SA can be performed not only by controlling the opening degree of the exhaust flow rate adjusting damper 15 but also by controlling the fan air volume, the rotational speed control of the dehumidifying rotor 36, and the like.

[0537] Also, in step SA3, when the temperature of the supply air SA is lower than the set temperature value, the force that maintains the current control. Working air flow rate Increase the temperature of the supply air SA by decreasing the flow rate of WA, etc. You can control it.

[0538] In addition, set date data such as the date and time of operation at the desired set temperature value is registered in the memory 77, and the date and time specified by the set date data registered in the current date and time In such a case, as described above, control may be performed so as to obtain a desired set temperature. Further, the ventilation flow rate may be controlled only by temperature control. [0539] Here, the memory 77 is a rewritable memory, and the set temperature value can be rewritten by operating the setting switch 75. As the setting switch 75, an operation panel provided in the ventilation device 1 or a remote control device connected by wire, wireless, infrared, or the like is used.

[0540] By rewriting the set temperature value registered in the memory 77, a desired supply air temperature can be obtained. The set temperature value registered in the memory 77 may be temperature data, or the rotational speed of the fan motor 72, the driving voltage of the fan motor 72, the damper opening degree by the damper motor 73, the driving voltage of the damper motor 73, or the like.

FIG. 35 is a flowchart showing another example of cooling control by the temperature sensor. Here, it is assumed that a desired set temperature value is registered in the memory 77 in advance. In addition, it is assumed that the fan motor 72 and the like are driven to perform a cooling operation.

Step SB1: The CPU 71 reads the temperature of the supply air S A from the temperature sensor 17. Or, the temperature of the room 102 is read from the temperature sensor 63.

[0543] Step SB2: The CPU 71 reads the set temperature value from the memory 77.

Step SB3: The CPU 71 compares, for example, the temperature of the supply air SA read from the temperature sensor 17 with the set temperature value read from the memory 77. If the temperature of the supply air SA is lower than the set temperature value, the current control is maintained without changing the fan speed, damper opening, etc., and the process returns to step SA1.

[0545] Step SB4: If the temperature of the supply air SA is higher than the set temperature value in the comparison with step SB3, the CPU 71 lowers the temperature of the supply air SA. Increase the amount of water supplied to the indirect vaporization element 11 by increasing the opening of the water supply valve 12

[0546] In the indirect vaporization cooling unit 4, as described above, the working air WA is cooled using the vaporization heat of water in the indirect vaporization element 11! /, So the amount of water supplied to the indirect vaporization element 11 is small. If it increases, the temperature of the working air WA decreases, and the temperature of the product air PA that receives the cold heat of the working air WA decreases. Therefore, the temperature of the supply air SA can be lowered.

[0547] Here, the set temperature value registered in the memory 77 can be rewritten. The explanation is also shown in Figure 34. You can combine the air flow control and the water supply control.

[0548] <Control by human sensor>

FIG. 36 is a flowchart showing an example of cooling control by the human sensor. Here, it is assumed that a desired set temperature value that can be switched according to the presence or absence of a person is registered in the memory 77. Further, it is assumed that the fan motor 72 and the like are driven to perform a cooling operation.

Step SC1: The CPU 71 reads the presence / absence of a person in the room 102 shown in FIG.

[0550] Step SC2: The CPU 71 reads the first set temperature value and the second set temperature value from the memory 77. Here, the first set temperature value is the cooling temperature when there is a person, and the second set temperature value is the cooling temperature when there is no person.

[0551] Step SC3: The CPU 71 determines whether or not the human sensor 62 has an output force.

[0552] Step SC4: If there is a person in the room 102 at step SC3, the CPU 71 sets the temperature of the supply air SA to the first set temperature value. By controlling the damper opening and the rotational speed control of the dehumidifying rotor 36 by adjusting the flow rate of the working air WA, for example, the temperature of the supply air SA is set to the first set temperature value.

[0553] Step SC5: If there is no person in the room 102 at step SC3, the CPU 71 sets the temperature of the supply air SA to the second set temperature value. The damper opening degree by 73 is controlled, for example, the flow rate of the working air WA is adjusted, and the temperature of the supply air SA is set to the second set temperature value.

[0554] In this way, by changing the cooling temperature depending on the presence or absence of a person, for example, if there is a person! / Or if the cooling temperature is set higher, the power consumption can be suppressed.

Here, the first set temperature value and the second set temperature value registered in the memory 77 can be rewritten by operating the setting switch 75. Thereby, a desired supply air temperature can be obtained.

FIG. 37 is a flowchart showing an example of ventilation amount control by the human sensor. Here, it is assumed that a desired ventilation flow value that can be switched according to the presence or absence of a person is registered in the memory 77. In addition, fan motor 72 etc. is driven and cooling operation is performed. Step SD1: The CPU 71 reads the presence / absence of a person in the room 102 shown in FIG.

[0558] Step SD2: The CPU 71 reads the first set ventilation flow value and the second set ventilation flow value from the memory 77. Here, the first set ventilation flow value is the ventilation flow rate when there is a person, and the second set ventilation flow value is the ventilation flow rate when there is no person.

[0559] Step SD3: The CPU 71 determines whether the human sensor 62 has an output force.

[0560] Step SD4: If there is a person in the room 102 based on the judgment in step SD3, the CPU 71 sets the ventilation flow rate to the first set ventilation flow value. Adjust the flow rate at which the supply air SA blows out and the flow rate at which the return air RA is sucked in by controlling the opening, etc., and make the return air flow rate the first set return air flow value.

[0561] Step SD5: If there is no person in the room 102 at step SD3, the CPU 71 sets the ventilation flow rate to the second set ventilation flow rate value. By controlling the damper opening, etc., the flow rate of the supply air SA and the flow rate of intake of the return air RA are adjusted, and the return air flow rate becomes the second set return air flow value.

In this way, by changing the ventilation flow rate depending on the presence or absence of a person, for example, when there is a person! /, If the ventilation flow rate is set low, the power consumption and the like can be suppressed.

[0563] Here, the first set ventilation flow value and the second set ventilation flow value registered in the memory 77 can be rewritten by operating the setting switch 75. As a result, a desired ventilation flow rate can be obtained.

[0564] <Start / stop control>

The ventilator 1 shown in Fig. 1 etc. functions as an air conditioner that controls the temperature of the living room by using the indirect evaporative cooling unit 4, and also controls the temperature by stopping the cooling function by the indirect evaporative cooling unit 4. It functions as a ventilation device that ventilates the room (replacement of outside air and return air) without being accompanied.

FIG. 38 is a flowchart showing an example of manual start-up / stop control. First, the manual stop operation of the cooling function will be described.

[0566] Step SE1: The CPU 71 reads the output of the cooling operation stop switch 76. [0567] Step SE2: The CPU 71 determines whether or not the output force of the cooling operation stop switch 76 is also a force at which cooling stop is instructed.

Step SE3: When the cooling stop is instructed in the determination at Step SE2, the CPU 71 closes the water supply valve 12a of the water supply / drainage device 12 shown in FIG. 1, for example, and stops the water supply to the indirect vaporization element 11. When the water supply to the indirect vaporization element 11 is stopped, the cooling air WA is not cooled by the evaporation of water, and the product air PA is not cooled. Therefore, the temperature of the supply air SA is not controlled by the indirect evaporative cooling unit 4. As a result, the cooling function can be stopped.

[0569] When the water supply valve 12a is closed and the water supply to the indirect vaporization element 11 is stopped, the CPU 71 may open the drain valve 12b to drain the water from the drain pan 13. As a result, when the cooling function is stopped for a long time, such as in winter, water can be left in the drain pan 13.

Step SE4: When the start of the cooling function is instructed in the determination at Step SE2, the CPU 71 opens the water supply valve 12a of the water supply / drainage device 12 shown in FIG. 1 to supply water to the indirect vaporization element 11, for example. When water is supplied to the indirect vaporization element 11, the boiling air WA is cooled by evaporation of the water, and the product air PA is cooled by the cold heat of the working air WA. Therefore, the temperature of the supply air SA is controlled by the indirect evaporative cooling unit 4, whereby the cooling function can be activated.

[0571] When the water supply valve 12a is opened, the CPU 71 closes the drain valve 12b so that water can be stored in the drain pan 13.

FIG. 39 is a flowchart showing an example of automatic start / stop control. Next, the automatic cooling function stop operation will be described. Here, in the memory 77, set date data such as the date and time when the cooling function is stopped is registered in advance.

[0573] Step SF1: The CPU 71 reads the current date data from a calendar function or the like (not shown).

[0574] Step SF2: The CPU 71 reads the set date data of the cooling stop period from the memory 77.

[0575] Step SF3: The CPU 71 sets the current date data and the set date read from the memory 77 Compare the data.

[0576] Step SF4: In comparison with Step SF3, if the current date is in the cooling stop period

The CPU 71 closes the water supply valve 12a of the water supply / drainage device 12 shown in FIG. 1, for example, and stops water supply to the indirect vaporization element 11. When the water supply to the indirect vaporization element 11 is stopped, the cooling function can be stopped as described above.

[0577] When the water supply valve 12a is closed and the water supply to the indirect vaporization element 11 is stopped, the CPU 71 may open the drain valve 12b to drain the water from the drain pan 13.

[0578] Step SF5: In comparison with Step SF3, the current date has entered the cooling stop period! /, NA! / ヽ, and CPU71 opens the water supply valve 12a of the water supply / drainage device 12 shown in FIG. Supply water to vaporization element 11 and activate the cooling function.

[0579] When the water supply valve 12a is opened, the CPU 71 closes the drain valve 12b so that water can be stored in the drain pan 13.

Here, in the flowchart of FIG. 39, the cooling function is stopped and started based on the date, but the set temperature value for stopping the cooling function is registered in the memory 77 and is not shown.

V, the outdoor temperature detected by the outside air temperature sensor is compared with the set temperature value.When the outdoor temperature falls below the set temperature value, the cooling function is stopped, and when the outdoor temperature exceeds the set temperature value, the cooling function is stopped. You can also start it up.

[0581] Here, the setting date data and the setting temperature value registered in the memory 77 can be rewritten by the operation of the setting switch 75. Thereby, the cooling function can be stopped for a desired period.
