On the other hand, the humidity control unit 3 has an outdoor air outlet 16 and an outdoor air inlet 17 on the side opposite to the connection with the fan unit 2. And the humidity control unit 3
Is divided into four spaces 3a, 3b, 3c and 3d by the sensible heat exchanger 7 and a plurality of partitions. The sensible heat exchanger 7 does not exchange moisture between the supply air SA and the exhaust EA, but performs only sensible heat exchange. The sensible heat exchanger 7 is formed in a substantially square prism shape, and has four side surfaces 7 serving as air inlets or outlets.
a, 7b, 7c, and 7d are arranged in the width direction at substantially the center of the humidity control unit 3 in a posture inclined with respect to the top and bottom surfaces of the humidity control unit 3. By providing a predetermined partition between the four side portions of the sensible heat exchanger 7 and the inner wall of the humidity control unit 3, the four spaces 3a to 3d are provided.
3d is formed.

The role of the four spaces 3a to 3d will be described below. First, the space 3a formed in the upper part on the indoor side
Communicates with a side surface 7a located above the indoor side of the sensible heat exchanger 7 and has a connecting portion communicating with an opening (not shown) formed in the casing 3e so as to communicate with the fan unit 2. ing. The opening and the opening through which the exhaust fan storage chamber 2b communicates are opposed to each other, whereby the space 3a communicates with the exhaust fan storage chamber 2b of the fan unit 2. Therefore, the space 3a serves as an indoor air suction passage, and the side surface 7a of the sensible heat exchanger 7 serves as a suction port.

A space 3 formed in a lower part on the indoor side.
b is a side surface 7 b located below the indoor side of the sensible heat exchanger 7.
And the connecting portion side communicates with an opening (not shown) formed in the casing 3 e so as to communicate with the fan unit 2. The opening and the opening through which the air supply fan storage chamber 2a communicates are opposed to each other, whereby the space 3b communicates with the air supply fan storage chamber 2a of the fan unit 2. Therefore, the space 3b serves as an air supply passage, and the side surface 7b of the sensible heat exchanger 7 serves as an outlet.

On the other hand, the space 3 formed in the lower part on the outdoor side
c is a side surface 7c located below the outdoor side of the sensible heat exchanger 7
And the outside air outlet 16. Therefore, the space 3c serves as an exhaust passage, and the side surface 7c of the sensible heat exchanger 7 serves as an outlet. The space 3d formed in the upper part on the outdoor side communicates with the side surface 7d located on the upper side of the outdoor side of the sensible heat exchanger 7 and also communicates with the outdoor side inlet 17. Therefore, the space 3d serves as an outside air suction passage, and the side surface 7d of the sensible heat exchanger 7 serves as a suction port.

Here, the four side surfaces 7a to 7c of the sensible heat exchanger 7
In 7d, opposing side surfaces communicate with each other via an air passage (not shown). That is, the side surfaces 7a and 7c and the side surfaces 7b and 7d are both in communication. Therefore, in the humidity control ventilator 1, the outside air suction passage 3d, the air supply passage 3b, and the air supply fan storage chamber 2a communicate with the air supply passage RS via the sensible heat exchanger 7 to form the air supply passage RS. Similarly, through the sensible heat exchanger 7, the exhaust fan storage chamber 2b, the indoor air suction passage 3a, and the exhaust passage 3c communicate in this order to form an exhaust passage RE.

That is, the outside air OA is sucked from the outdoor suction port 17 by driving the air supply fan 4, and then passes through the air supply path RS and enters the room as the air supply SA from the indoor side outlet 14. Supplied. On the other hand, the indoor air RA is
By driving the exhaust fan 5, the indoor suction port 1 is
After the air is sucked in from the air outlet 3, the air is exhausted from the outdoor air outlet 16 to the outdoor as the exhaust air EA through the exhaust path RE.
The outside air outlet 16 and the outside air inlet 17 are connected to the outside by a duct (not shown).

A dehumidifier 9 is disposed in the outside air suction passage 3d, and an outside air treatment filter 18 for removing foreign substances such as dust and pollen is provided between the dehumidifier 9 and the outdoor suction port 17. Are located. Further, a moisture permeable humidifier 8 is arranged in the air supply passage 3b, and a water supply tank 20 is arranged in the vicinity thereof. Therefore, in the air supply path RS, the dehumidifier 9, the sensible heat exchanger 7, the humidifier 8, and the air supply fan 4 are arranged in this order from the upstream side along the flow of the outside air OA (air supply SA).

The dehumidifier 9 is realized by a heat exchanger, connected to an outdoor unit (not shown) installed outdoors by a communication pipe (not shown), and functions as an evaporator of a refrigerant circuit. In addition, the distal end of the refrigerant pipe (the gas pipe 25 and the liquid pipe 26) of the dehumidifier 9 is guided to a connection storage space 19 formed in the exhaust passage 3c. This connection part storage space 19
Is installed below the side surface (maintenance surface 1a) of the humidity control unit 3 and is covered by a removable cover.

The moisture permeable membrane type humidifier 8 is constituted by arranging a plurality of moisture permeable membrane pipes vertically and horizontally so as to be parallel to each other, and arranging humidifying water around the moisture permeable membrane pipe. This is to impart moisture to the air passing through the pipe. The water supply tank 20 stores tap water supplied from a water supply pipe 21 connected to a water pipe, and supplies the stored tap water to the moisture permeable humidifier 8 as humidified water using a height difference. is there.

An air filter 22 is disposed in the indoor air suction passage 3a so as to cover substantially the entire side surface 7a of the sensible heat exchanger 7. The air filter 22 is for removing foreign matter such as dust in the room.

The sensible heat exchanger 7, the moisture permeable humidifier 8 and the dehumidifier 9 all use water.
Alternatively, it is a component in which water is generated (condensed) during operation, that is, a so-called water component. Therefore, a drain pan (not shown) is arranged on the entire bottom of the humidity control unit 3 to store condensed water and excess humidified water. The drain water stored in the drain pan is drained outside through a drain outlet 23 through a drain hose (not shown). The drain outlet 23 is formed substantially at the center near the bottom of the side where the outdoor outlet 16 and the like are provided. In addition, a plurality of attachment portions 15 to which the installation plates 11 are attached are formed in the upper part of the humidity control unit 3.

Next, the fan unit 2 and the humidity control unit 3
The connection structure with the will be described. The fan unit 2 and the humidity control unit 3 are opposed to each other, that is, the casing 2.
c between the side of the casing 3e and the side of the casing 3e.
Are connected by the connecting means 24a arranged on the upper surface side of the connecting portion and the connecting portion 24b arranged on the lower surface side of the connecting portion. Here, the connection means 24a and 24b have the same structure except that they are arranged upside down because they are arranged at different positions. Therefore, the connection means 24a on the upper surface will be described.

FIG. 4 is an enlarged sectional view showing the structure of the connecting means 24a, and FIG. 5 is an enlarged plan view showing a part of the connecting means 24a. The connection means 24a includes a pair of guide rails 46 and 47 and a connection key 48 which is detachably attached to the guide rails 46 and 47.

The guide rail 46 extends in the width direction of the casing 2c in the vicinity of a corner on the upper surface of a side portion of the fan unit 2 which is a connection portion of the casing 2c.
The guide rail 46 is a member having an L-shaped cross section, and includes a support portion 46a formed in an elongated plate shape and a guide portion 46b similarly formed in an elongated plate shape. The support portion 46a is attached to a side portion of the casing 2c by a screw or the like in an inverted L-shaped posture so that the guide portion 46b extends to the side opposite to the humidity control unit 3. Here, the guide portion 46b is arranged at a fixed interval from the upper portion of the casing 2c.

The guide rail 47 is provided for the humidity control unit 3.
In the vicinity of a corner on the upper surface of a side portion which is a connection portion of the casing 3e, the casing 3e extends in the width direction of the casing 3e.
The guide rail 47 is a member having an L-shaped cross section similarly to the guide rail 46, and has an elongated plate-like support portion 47a.
And a similarly elongated plate-shaped guide portion 47b. The support portion 47a is attached to a side portion of the casing 3e by a screw or the like in an inverted L-shaped posture so that the guide portion 47b extends to the side opposite to the fan unit 2.
Here, the guide portion 47b is disposed at a fixed interval from the upper portion of the casing 3e. This interval is set to substantially the same length as the interval between the guide portion 46b and the casing 2c.

On the other hand, the connection key 48 is formed in an elongated plate shape, and at both ends in the width direction of the connection key 48 is engaged with each end of the guide portions 46b, 47b of the pair of guide rails 46, 47. It has parts 48a and 48b. The engaging portions 48a and 48b are U-shaped portions in cross section, and are formed facing each other with the opening side facing inward.

In connection, the sealing member 45 is attached to any one of the connecting portions of the casings 2c and 3e in advance, and then the connecting portions are opposed to each other so as to sandwich the sealing member 45.
Two units 2 and 3 are arranged. Then, the connection key 48 is connected to the engagement portions 48a, 48b by the guide portions 46b,
The guide rails 46 and 47 are inserted by being inserted in the direction of the arrow R (see FIG. 5) from one end in the longitudinal direction so that the guide rails 47b are inserted. This allows the guide rails 46, 47,
That is, the casing 2c of the fan unit 2 and the casing 3e of the humidity control unit 3 are close to each other,
Are connected in a compressed state.

The end surface of the sealing material 45 is the casing 2.
It is formed in a flat plate shape along the outer circumferences of c and 3e, and has two through holes at predetermined positions. These two through-holes are provided between the exhaust fan storage chamber 2b and the indoor air suction passage 3a.
And an opening formed in each of the casings 2c and 3e for communicating the air supply passage, and an opening formed in each of the casings 2c and 3e for communicating the air supply fan storage chamber 2a and the air supply passage 3b. Yes, it is. Accordingly, airtightness between the air supply path RS and the exhaust path RE is ensured, and airtightness between the inside (the air supply path RS and the exhaust path RE) of the casings 2c and 3e and the outside is maintained.

In the guide rails 46 and 47, the ends of the guide portions 46b and 47b on the maintenance surface 1a side are inclined such that the front ends thereof are tapered toward the maintenance surface 1a. That is, the guide portion 46
In b and 47b, the end on the insertion side of the connection key 48 is formed in a tapered shape. This is to make it easier to insert the connection key 48 when mounting it on the guide rails 46, 47.

The humidity control ventilator 1 having such a configuration can be operated in various operation modes according to the season (temperature, humidity, etc. of the outside air OA). Fresh air like spring and autumn
When A is comfortable, only the air supply fan 4 and the exhaust fan 5 are driven to perform the heat exchange ventilation mode. In this mode, neither the moisture permeable humidifier 8 nor the dehumidifier 9 is operated. In the heat exchange ventilation mode, outdoor fresh air OA
Is taken into the room through the outside air processing filter 18 and the dirty indoor air RA is discharged to the outside, so that pollen and dust can be prevented from entering and the room can be filled with fresh air. be able to. However,
In this case, since the outside air OA and the room air RA have substantially the same temperature, heat exchange by the sensible heat exchanger 7 is not performed.

When the humidity of the outside air OA is high, such as during the rainy season, autumn rainy season, or summer, the dehumidifier 9 is operated in addition to the operation of the air supply fan 4 and the exhaust fan 5 to set the dehumidification heat exchange ventilation mode. Do. In this mode, the indoor air RA discharged from the sensible heat exchanger 7 is cooled and dehumidified by the dehumidifier 9 while ventilating in the same manner as the heat exchange ventilation mode.
And heat is exchanged between them to supply them indoors. Therefore, during the rainy season and autumn rainy season when the outside air OA is at an appropriate temperature, ventilation and dehumidification can be performed without lowering the room temperature, and the occupants can spend comfortably without feeling cold.

In summer, when the temperature of the outside air OA is high, the humidity can be lowered and the temperature can be lowered to about room temperature, so that the occupants can spend comfortably without feeling the heat.

When both the temperature and the humidity of the outside air OA are low as in winter, the humidifier 8 is operated to perform the humidification heat exchange ventilation mode in addition to the driving of the air supply fan 4 and the exhaust fan 5. In this mode, while performing ventilation in the same manner as in the heat exchange ventilation mode, the sensible heat exchanger 7 performs heat exchange between the outside air OA and the discharged indoor air RA to heat the outside air OA. Humidify and supply indoors. Therefore, an indoor environment with an appropriate humidity can be realized, the occupants can spend comfortably, and the so-called energy-saving heating can be performed because the exhaust heat of the indoor air RA is reused.

In the humidity control ventilator 1 described above, since the fan control unit 2 and the humidity control unit 3 are divided, the units 2 and 3 can be reduced in size and weight, and can be easily handled. Therefore, even one worker can easily and safely carry each unit 2 and 3 to the installation location. This is particularly effective when the installation location is a high place such as the ceiling of the second floor of a house.

Similarly, even a single worker can easily and safely install the units 2 and 3 at the installation location. This is particularly effective when the installation work is performed in a narrow and low space such as the space above the ceiling, or when the installation work is suspended from the house frame above the ceiling and installed.

Further, after the units 2 and 3 are suspended, the units 2 and 3 are connected to each other by the connecting means 24a and 24b arranged on the upper and lower sides of the outer peripheral portion, so that the connecting operation can be easily performed. It can be carried out. Further, the connection work can be performed by one-touch operation while ensuring airtightness only by inserting the connection key 48 into the guide rails 46 and 47 after interposing the seal material 45 between the units 2 and 3. Burden is reduced. Furthermore, since the connection key 48 only has to be inserted in the horizontal direction, the connection can be easily performed even in a space having a low height such as the inside of a ceiling. Further, even when the side opposite to the maintenance surface 1a is suspended close to the wall surface of the house, the connection work is performed on the upper surface side and the lower surface side of the units 2, 3, so that the space between the house and the wall surface is reduced. It can be hung without awareness.

In the humidity control ventilator 1, the water supply parts 7,
Since the drain pan may be arranged only in the humidity control unit 3 in which the components 8 and 9 are combined, the drain pan can be downsized and the drain water can be easily treated. Further, there is no need to consider waterproof measures for components other than the water components 7, 8, 9 (such as the air supply fan 4 and the exhaust fan 5), and the water components 7, 8, 9 can be arranged close to each other. The size of the humidity control unit 3 can be reduced. Along with this, it is possible to reduce the size of the humidity control ventilator 1 as a whole.

Further, in the humidity control ventilator 1, since the two fans 4 and 5 that use electric power are separated from the water supply parts 7, 8, and 9 and are integrated into one fan unit 2, wiring is performed. The structure and the waterproof structure can be simplified.
Further, by making the unit, the space in the casing 2c can be effectively used, and the fan unit 2
Can be reduced in size. Along with this, it is possible to reduce the size of the humidity control ventilator 1 as a whole.

In the humidity control ventilator 1, the humidifier 8 is arranged on the suction side of the air supply fan 4 in the air supply path RS. With such an arrangement, the wind speed distribution of the supply air SA (outside air OA) passing through the humidification region where the humidifier 8 performs the humidification process becomes substantially uniform. This is because, in the air supply fan 4, when air is blown out from the outlet, the space near the suction port becomes negative pressure, and the air moves from the entire periphery of the negative pressure space toward the negative pressure space. This is because the variation in the wind speed distribution is smaller in the suction side space than in the blowing side space.

Therefore, the humidifier 8 can sufficiently exhibit humidification capability over the entire humidification region, so that sufficient humidification can be performed on the supply air SA, and the humidifier 8 can be reduced in size. Can be achieved. Further, with the downsizing of the humidifier 8, the downsizing of the humidity control ventilator 1 can be achieved.

Particularly, in the moisture permeable membrane humidifier 8, since the space in the moisture permeable membrane pipe corresponds to the humidification area where the supply air SA is humidified, the humidification capacity is sufficient throughout the humidification area. In order to exert the above, it is necessary to make the supply air SA pass through each moisture permeable membrane pipe evenly, that is, at a substantially uniform speed. Therefore, by arranging the moisture permeable humidifier 8 on the suction side of the air supply fan 4 as in the present embodiment, the speed of the supply air SA passing through each moisture permeable membrane pipe can be made substantially uniform. The humidifying ability can be sufficiently exhibited. Thereby, the humidification performance can be improved.

In the humidity control ventilator 1, the air supply path RS and the air exhaust path RE are installed adjacently and in parallel, and the air supply fan 4 and the air exhaust fan 5 are arranged at positions facing each other. . By thus arranging the components in a coherent manner, it is possible to reduce the size of the configuration. further,
In the air supply path RS, the air supply fan 4 is arranged at a position facing the exhaust fan 5, and in the exhaust path RE, the exhaust fan 5 is arranged at a position facing the air supply fan 4. Therefore, a space that has not been used conventionally can be effectively used, and both the air supply path RS and the exhaust path RE can be shortened by a length corresponding to one fan. As a result, the size of the humidity control ventilator 1 can be further reduced.

Further, in the humidity control ventilator 1, the sensible heat exchanger 7
The humidification is performed on the supply air SA heated by the heating.
Since the amount of saturated water vapor increases as the temperature rises,
The humidification amount is greatly increased as compared with the case where the supply air SA before heating is humidified. As a result, sufficient humidification of the supply air SA becomes possible, and humidification performance can be improved.
This is particularly effective when humidifying in winter or the like when the outside air OA is low.

Further, in the humidity control ventilator 1, only heat is transferred between the supply air SA and the exhaust EA by the sensible heat exchanger 7, so that the odor and the dirt are supplied together with the moisture in the exhaust EA. The air is prevented from being passed back to the room by being passed to the air SA, and only fresh air can be taken into the room.
Thereby, the comfort of the indoor space can be improved. It is needless to say that a heat exchanger that transfers both heat and moisture may be used instead of the sensible heat exchanger 7, but in this case, the comfort of the indoor space is reduced by the sensible heat exchanger. 7
Will be impaired compared to the case of using.

As described above, according to the humidity control ventilator of the first aspect, since the unit is divided into a plurality of units, the size and weight of each unit can be reduced, and the handling thereof is easy. Therefore, installation work including loading work can be performed easily and safely. Further, since the connection between the units is performed from the outside, the work is easy.

According to the humidity control ventilator of the second aspect, when hanging and installing, the connection work between units is simplified.

Further, according to the humidity control ventilator of the third aspect,
By configuring the water supply unit in which the water supply parts are combined, the drain pan may be disposed only in the unit, so that the size of the drain pan can be reduced and the drain water can be easily treated. In addition, since the water supply parts can be arranged close to each other without considering waterproof measures against other parts, the water supply unit can be reduced in size, and accordingly, the overall humidity control ventilation device can be reduced in size. It becomes possible.

According to the humidity control ventilator of the fourth aspect, the air supply fan and the exhaust fan are separated from the water supply parts and are integrated into one unit, thereby simplifying the wiring structure and the waterproof structure. Can be achieved. Further, by arranging the two fans close to each other, the space in the casing can be effectively used, and the size of the fan unit can be reduced. As a result, the overall size of the humidity control ventilator can be reduced. It becomes possible.
