It is configured to perform a cooling operation or a heating operation by controlling to operate as a condenser and an evaporator.

[0003] An outdoor fan for generating an air flow is disposed in the outdoor unit. The outdoor fan introduces outside air, and exchanges heat between the refrigerant and air passing through the interior of the outdoor heat exchanger. I do.

Similarly, the indoor unit is also provided with an indoor fan for generating an air flow inside the indoor unit casing, and the indoor fan draws indoor air to remove the refrigerant passing through the indoor heat exchanger. Heat exchange with air.

In general, in a heating operation of an air conditioner, only the room temperature rises without supplying moisture, so that the relative humidity in the room often drops significantly. Therefore, it has been proposed to provide a humidifying unit in an air conditioner to supply humidified air to a room. The humidifying unit, for example, comprises a disc-shaped rotor made of a porous moisture-absorbing material such as zeolite that absorbs moisture in the air and releases the absorbed moisture by heating, and rotatably supports the rotor. I do. Moisture-absorbing fan for introducing outside air to generate moisture flowing through a part of the rotor to adsorb moisture in the air to the rotor, and humidified air containing moisture released from the rotor to the indoor unit side And a humidifying fan for generating an air flow for the humidification. The air flow from the humidifying fan and the air flow from the humidifying fan are configured to pass through the rotor at different positions in the rotation direction of the rotor, and a heater for heating the rotor is provided at a position where the air flow from the humidifying fan passes.

For example, when the rotor drive motor 61, the heater body 66, and the moisture absorption fan motor 83 in the humidification unit 4 are of the AC type and the humidification fan motor 403 is a DC motor, the humidification fan drive unit 223 The power supply line connected to the humidifying fan motor 403 is a DC line, and the other power supply lines are 100/200 V AC.
It can be a line.

The thermistor 402 for detecting air temperature after passing through the humidifying rotor in the humidifying unit 4 is connected to the indoor unit control unit 201 by a detected temperature signal line, and sends the detected temperature signal to the indoor unit control unit 201. It is configured to transmit.

In this embodiment, there is no need to provide a control unit on the humidifying unit 4 side, and the power supply unit can be shared with the indoor air conditioning unit 2, so that the number of parts can be reduced and the cost can be reduced. It becomes possible. Further, since the indoor air conditioning unit 2 and the humidification unit 4 are mounted close to each other, the wiring length is shortened, and the workability is improved.

<E. Other Embodiments> Rotor drive motor 61 and heater body 6 arranged in humidification unit 4
6. It is conceivable that all of the humidifying fan motor 403 and the moisture absorbing fan motor 83 have the DC specification. In this case,
It is possible to simplify a control circuit for controlling each unit.
