I have.

When the humidity control operation is instructed, the outside air guided through the outside air passage 5 passes through a part of the humidity control rotor 13. With the rotation of the rotor 13, the portion through which the outside air has passed faces the indoor air ventilation path 8, and the room air guided through this indoor air ventilation path passes.

The heater 14 is shown as being disposed in the U-turn portion of the indoor air passage 8 formed in a substantially U shape, but actually heats a part of the humidity control rotor 13. Location and in the room air passage.

The outside air passage 5 has a plurality of, here 2
The first and second filters 15 and 16 are provided. The first filter 15 located on the upstream side is fitted in the outside air suction port 3. The second filter 16 is provided downstream of the first filter 15 and up to the humidity control rotor 13.

The first filter 15 fitted in the outside air suction port 3 is selected to have a mesh larger than that of the second filter 16 on the downstream side. And the second
The filter 16 is disposed in a state of being obliquely inclined with respect to the ventilation cross section. Naturally, the first filter 15 may also be inclined obliquely with respect to the ventilation cross section.

The unit main body 1 accommodates a main body controller 18 composed of control electric parts and a wiring board.
A power supply line 19a and a signal line 19b connected to the main body controller 18 are extended to the indoor unit 2 side as a crossover wiring 19 as described later. In particular, the signal line 19b is electrically connected to an indoor controller 20 housed in the indoor unit 2, and the main controller 18 and the indoor controller 20 constitute a control device (control means) 21. .

A through hole 22 is provided in a wall portion sandwiched between the unit body 1 and the indoor unit 2, and a sleeve 23 having the same cross-sectional shape as the through hole 22 is fitted. The cross section of the sleeve 23 is partitioned into a suction guide section 25 and a blowout guide section 26 connected to the indoor air suction port 6 on the back of the unit body 1 and the indoor air blowout port 7, respectively. The wiring space 27 for the wiring is secured.

FIG. 3 shows a cross section of the sleeve 23.
Here, the sleeve 23 is configured for exclusive use with the non-water-supplying humidity controller. The blow-out guide 26 has a cross-sectional area of at least half of the entire cross-section of the sleeve 23.
Is formed in almost the remaining cross-sectional area. The wiring space 27 is provided between the guide portions 25 and 2.

On the contrary, there is no setting that the cross-sectional area of the blow-out guide section 26 is smaller than the cross-sectional area of the suction guide section 25.

The air conditioner K is composed of the indoor unit A and an outdoor unit (not shown). Crossover pipes and crossover wiring provided between these units are connected to a sleeve inserted into a through hole in a wall. It is inserted.

Therefore, it is conceivable to share the sleeve for the air conditioner and the sleeve for the humidity controller. FIG.
This is an example in which an air conditioner and a humidity controller are shared by two sleeves 23A. In this sleeve 23A, there is a partition plate 30 that divides the inside of the sleeve into a half, leaving a part inside. The right side of the figure is a space 31 for an air conditioner, and the left side is a space 32 for a humidity controller.

The upper part of the figure of the space 31 for the air conditioner

It is 4. In the remaining partitioned space 31, a gas pipe 35 for an air conditioner and a liquid pipe 36 for an air conditioner are provided.
And a drain hose 37 for an air conditioner are inserted therethrough.

Above the space 32 for the humidity controller, there is provided a space 38 through which the connecting wires 19 such as the power supply line 19a and the signal line 19b run between the unit main body 1 and the indoor unit 2 of the humidity controller. Provided.

The remaining space 32 for the humidity controller is
An outlet guide passage 26a having a large cross-sectional area and a suction guide passage 25a having a smaller cross-sectional area are formed non-uniformly by the auxiliary partition plate a.

As described above, if one sleeve 23A is used for both the air conditioner and the humidity controller, not only the labor for providing the through-holes is reduced, but also the appearance is reduced. The outlet guide path 26a in the space 32 for the humidity controller.
The sectional area relationship between the suction guide path 25a and the suction guide path 25a is exactly the same as that described with reference to FIG.

As shown in FIGS. 1 and 2 again, the unit outlet 40 is opened in the front part of the indoor unit 2 and the unit inlet 41 is opened in the lower part. Above the unit suction port 41, there is provided a display section H provided with LEDs for displaying operation-stop and necessary control.

The unit outlet 40 forms an opening at one end of a blowing auxiliary ventilation passage 42 provided in the indoor unit 2, and the other opening of the ventilation passage 42 is connected to the sleeve 23.
(23A) and communicates with the outlet guide path 26 (26a).

The unit suction port 41 forms one end opening of a suction auxiliary ventilation passage 43 provided in the indoor unit 2, and the other end opening of the ventilation passage 43 is connected to the sleeve 23 (2).
It communicates with 25 (25a) to the suction guideway provided in 3A). A filter 44 is provided in the unit suction port 41.
Is fitted.

The power cord 27 extending from the indoor unit 2 (or the power line 19a described above)
Is electrically connected to the same outlet 45 together with the power cord 33 extending from the indoor unit A of the air conditioner, as shown in FIG.

Alternatively, as shown in FIG. 5B, the indoor unit 2 and the indoor unit A are connected to the power line 19a and the signal line 19b.
And the power cord 3 of the indoor unit A
Only 3 may be connected to the outlet 45. In this case, a power cord connected to the indoor unit 2 is unnecessary as compared with the case (A), so that the appearance is neat.

When the humidity control operation is instructed, the processing fan 10 and the regeneration fan 11 are driven to perform a blowing operation, and the humidity control rotor 13 rotates. When driven, the heater 14 generates heat.

The outside air is sucked from the outside air suction port 3 and guided to the outside air passage 5, and passes through the humidity control rotor 13 on the way.
The humidity control rotor 13 is continuously rotating, and the passage portion of the outside air sequentially faces the indoor air passage 8 with the rotation of the humidity control rotor.

The outside air that has passed through the humidity control rotor 13 passes through the remaining portion of the outside air passage 5 and is blown out from the outside air outlet 4 to the outside. The outside air sucked from the outside air suction port 3 passes through the two filters 15 and 16 before reaching the humidity control rotor 13, and dust contained in the outside air is filtered and clogged in the humidity control rotor 13. Does not occur.

On the other hand, the room air is drawn in from the unit suction port 41 of the indoor unit 2, filtered by the filter 44, and then guided to the suction guide path 32 of the sleeve 23 through the suction auxiliary ventilation path 43. And the unit body 1
Inside, the air flows along the indoor air passage 8 and passes through the humidity control rotor 13 which continues to rotate.

Since the heater 14 heats the humidity control rotor 13, the moisture absorbed by the humidity control rotor from the outside air evaporates. The evaporated moisture is mixed with the room air, and the room air is humidified.

The room air exits from the room air passage 8 in the unit main body 1 and is supplied to the outlet guide passage 2 of the sleeve 23.
6 and the auxiliary ventilation passage 4 of the indoor unit 2
The air is blown into the room through the unit outlet 40 through the second air outlet 2. Humidified air will be blown into the room,
As a result, the humidity control effect of the unsupplied water is obtained.

In the non-water-supplying humidity controller described above, the processing fan 10 and the regeneration fan 11, which are noise-generating blowers, and the humidity control rotor 13 which is driven to rotate large are accommodated in the unit body 1 outside the room. By doing so, the noise reduction due to the sound insulation of the wall is achieved, and the air volume is increased accordingly,
It can lead to greater capacity.

In addition, at the time of humidity control, generally, it is necessary to increase the processing air volume since the moisture is absorbed from the air having a low outside air content during the heating period and having a low moisture content. In this method, since the outside air guided to the outside air ventilation path 5 which is the processing side ventilation path does not pass through the inside of the sleeve 23 penetrating the outer wall W, a decrease in the air volume caused by passing through the sleeve is avoided.

Since the ventilation passage 8 for leading the indoor air and the ventilation passage 5 for leading the outside air are completely independent paths, even if the mutual ventilation is extremely increased, the natural ventilation in the room is greatly changed. Without heat leakage.

A communication portion 9a communicating with each other is provided at a close position between the outside air passage 5 and the room air passage 8, and a damper mechanism 9b is provided so as to be openable and closable. Is possible. In addition, the moisture of the humidified indoor air can be recovered by the rotor by passing through the humidity control rotor 13 after passing through the damper mechanism 9b, thereby reducing moisture loss due to ventilation.

This humidity controller has an outdoor unit body 1
And the indoor unit 2 on the indoor side, so that transmission / reception, display functions, and maintenance of the indoor filter 44 can be performed from the indoor side. Is becoming

The processing fan 10 of the outside air passage 5 and the regeneration fan 11 of the room air passage 8 are both arranged inside the external unit body 1 and are not provided inside the indoor unit 2. As a result, the number of sources of room noise is reduced and quietness can be obtained.

The sleeve fitted into the through-hole 22 of the outer wall W is the sleeve 23 for the humidity controller alone or the sleeve 23A shared with the air conditioner. , 25a are set larger than the cross-sectional area.

As a result, the ventilation system for the room air can be optimized, and a large air volume and a large capacity can be obtained. In particular, when a sleeve shared with an air conditioner is used, the effect is remarkable.

The outside air outlet 4 and the outside air inlet 3 are
Since the opening is formed on the lower surface of the unit main body 1 and is directed downward, it is possible to reliably prevent rainwater from entering without providing a drip-proof plate or the like and to secure a large air volume. Further, the amount of dust adhering to the first and second filters 15 and 16 provided in the outside air passage 5 is reduced, and the life of filter clogging is extended.

A plurality of, here, first and second filters 15 and 16 are arranged in the outside air passage 5, and the first
Of the filter 15 of the second filter 1 on the upstream side
We chose something smaller than 6. Therefore, large dust can be captured by the first filter 15 and fine dust can be captured by the second filter 16, so that both filters can be used effectively and the life of filter clogging can be extended. Further, since the second filter 16 is disposed obliquely with respect to the cross section of the air passage 5, the surface area of the filter can be secured and the life is extended.

As shown in FIG. 5 (A), the power supply in the case where the non-water-supply / humidity controller is an independent unit is taken from the outlet above the wall for the indoor air conditioner, and the wiring is performed. The appearance can be improved.

As shown in FIG. 5B, the indoor unit A of the air conditioner and the indoor unit 2 of the humidity controller are connected to the power line 1.
9a and the signal line 19b are connected and operated in conjunction with each other, whereby the temperature and humidity of the living room space can be controlled and the optimum comfort can be obtained.

[0071]

As described above, according to the present invention, the air conditioner is provided to ensure the air conditioning function, and the main constituent means is placed on the outside wall surface, so that the indoor noise can be reduced. It is possible to obtain an effect that the air volume is increased and a large humidity control ability is obtained.
