  By the way, as an example of the conventional humidity control apparatus, a humidity control apparatus in which two heat exchangers are arranged by providing an air path in the case is conceivable. In this humidity control apparatus, an air supply fan for supplying air into the room and an exhaust fan for exhausting air to the outside are arranged in the air path in the case, and the air to be dehumidified passes through one heat exchanger, Contrary to the first ventilation mode in which the air to be humidified passes through the other heat exchanger, conversely, the air to be humidified passes through one heat exchanger and the first air to be dehumidified is the other second heat exchanger. By switching the second ventilation mode that passes through the air in accordance with the circulation direction of the refrigerant in the refrigerant circuit, one of the dehumidified air and the humidified air can be supplied into the room as humidity-controlled air.

However, in that case, in the above case, if the fan discharge port is disposed near each of the two openings that communicate with the room and serve as the air supply port and the room air intake port, the blowing sound is directly generated in the room. Leakage and difficulty in terms of noise. In particular, in the so-called cassette type in which the air supply port and the indoor air intake port are exposed in the room, the problem of the noise becomes more significant than the type in which the air supply port and the indoor air intake port are not exposed in the room. Unavoidable.

  The present invention has been made in view of such various points, and its purpose is not limited to the above cassette type, and in a general humidity control device, by specifying the arrangement structure of the fan, the blowing sound of the fan leaks into the room. It is to try to reduce as much as possible.

  In order to achieve the above object, according to the present invention, two fans are arranged on the outdoor side away from the indoor side in the air path, and the fan that supplies air toward the indoors is a pushing fan. The fan that sucks in air from the room is a suction fan.

Specifically, according to the first aspect of the present invention, there is provided a humidity control apparatus that supplies one of the dehumidified first air and the humidified second air to the room and discharges the other to the outside, wherein the first air carrying the adsorbent is provided. 1 and the second heat exchangers (2) and (3) are connected to perform a refrigeration cycle, and the refrigerant circuit (B) capable of reversing the refrigerant circulation direction and the internal air passages (41) and (42) A case (10) in which the heat exchangers (2) and (3) are disposed, an air supply fan (45) disposed in the air passages (41) and (42) for supplying air into the room, and an outdoor unit An exhaust fan (46) for exhausting air to the air, a first ventilation mode in which the first air passes through the first heat exchanger (2) and the second air passes through the second heat exchanger (3), and The second ventilation mode in which the second air passes through the first heat exchanger (2) and the first air passes through the second heat exchanger (3) is set in the refrigerant circulation direction in the refrigerant circuit (B). Equipped with multiple dampers to switch according to The air supply fan (45) is disposed upstream of the first and second heat exchangers (2) and (3) in the air path (41), and the exhaust fan (46) is disposed in the air path (42). ) In the downstream side of the first and second heat exchangers (2) and (3).

According to the above configuration, when the room is humidified, for example, first, the refrigerant circuit (B) uses the first heat exchanger (2) as a condenser and the second heat exchanger (3) as an evaporator. In addition to the operation, the damper is switched to enter the second ventilation mode in which the second air passes through the first heat exchanger (2) and the first air passes through the second heat exchanger (3). As a result, the heating of the adsorbent in the heat exchanger (2) passes through the first heat exchanger (2) in which the second air becomes a condenser by the operation of the air supply fan (45). Regeneration) releases moisture from the adsorbent into the air, humidifies the air, and the humidified second air is blown into the room as humidity-controlled air. On the other hand, by the operation of the exhaust fan (46), the first air passes through the second heat exchanger (3) serving as an evaporator, and is cooled by evaporative heating of the adsorbent in the heat exchanger (3). Thus, the adsorbent adsorbs moisture in the air to dehumidify the air, and the dehumidified first air is blown out of the room.

Thereafter, the refrigeration cycle operation of the refrigerant circuit (B) is switched to the refrigeration cycle operation in which the second heat exchanger (3) serves as a condenser and the first heat exchanger (2) serves as an evaporator. Accordingly, the damper is switched to the first ventilation mode in which the first air passes through the first heat exchanger (2) and the second air passes through the second heat exchanger (3). Thus, the second air is humidified by the heat exchanger (3) via the second heat exchanger (3) serving as a condenser by the operation of the air supply fan (45). The air is blown into the room as humidity control air. On the other hand, by the operation of the exhaust fan (46), the first air is dehumidified by the heat exchanger (2) via the first heat exchanger (2) serving as an evaporator, and this dehumidified air is obtained.

Thus, the second air is humidified and blown out into the room, and instead, the first air is dehumidified and discharged out of the room.

On the other hand, in the case of dehumidifying the room, for example, first, the refrigerant circuit (B) uses a first heat exchanger (2) as a condenser and a second heat exchanger (3) as an evaporator. In addition to the operation, the damper is switched to enter the second ventilation mode in which the second air passes through the first heat exchanger (2) and the first air passes through the second heat exchanger (3). Thus, the first air is dehumidified by the heat exchanger (3) via the second heat exchanger (3), which is an evaporator, by the operation of the air supply fan (45). The air is blown into the room as humidity control air. On the other hand, by the operation of the exhaust fan (46), the second air is humidified by the heat exchanger (2) via the first heat exchanger (2) serving as a condenser, and the humidified air. Is blown out.

Thereafter, the refrigeration cycle operation of the refrigerant circuit (B) is switched to the refrigeration cycle operation in which the second heat exchanger (3) serves as a condenser and the first heat exchanger (2) serves as an evaporator. Accordingly, the damper is switched to the first ventilation mode in which the first air passes through the first heat exchanger (2) and the second air passes through the second heat exchanger (3). Thus, the first air is dehumidified by the heat exchanger (2) via the first heat exchanger (2) serving as an evaporator by the operation of the air supply fan (45). The air is blown into the room as humidity control air. On the other hand, by the operation of the exhaust fan (46), the second air (RA) is humidified by the heat exchanger (3) via the second heat exchanger (3) serving as a condenser. The blown air is blown out to the outside.

  Next, the operation is switched to the first refrigeration cycle operation and the aeration mode, and thereafter, the two refrigeration cycle operations and the aeration mode are repeated. Thus, the first air is dehumidified and blown out into the room, and instead, the second air is humidified and discharged out of the room.

It becomes a route to the air supply port (17) through the ventilator (3), the seventh space (27), the eighth damper (38) and the fifth space (25), and the exhaust route (42) 18) to 6th space (26), 2nd damper (32), 4th space (24), 1st heat exchanger (2), 3rd space (23), 5th damper (35), 9th space (29) and the tenth space (30) through which the route reaches the exhaust port (16).

Then, by the operation of the air supply fan (45), the outdoor air (OA) sucked from the outside air suction port (15) flows through the air supply path (41), and becomes the condenser in the middle thereof. It is sent to the heat exchanger (3). In the second heat exchanger (3), the adsorbent carried on the outer surface is heated by the refrigerant, and moisture is desorbed from the adsorbent.
