る。 Therefore, in the first embodiment, during normal cooling operation when the temperature controller 20 is turned ON, the high temperature and high pressure gas discharged from the compressor 1 is discharged from the branch pipe 10 when the solenoid valve 11 is closed. Therefore, the entire amount flows to the condenser 2.
After being condensed and liquefied, the gas is expanded in the expansion mechanism 4 to lower the pressure, and further vaporized in the evaporator 5 to become a low-pressure gas and returned to the compressor 1. This cycle is repeated. At this time, in the indoor unit A, the air sucked in from the suction port 14 is cooled by the evaporator 5 when it passes through the evaporator 5, becomes cold air, and is then blown out from the blow-off port 15, so that the air can be cooled indoors. When the temperature decreases and the indoor temperature becomes below a predetermined temperature, the temperature regulator 20 is turned OFF to stop the cooling operation, and when the indoor temperature becomes above the predetermined temperature again, the temperature regulator 20 is turned off.
The indoor temperature is kept constant at approximately the predetermined temperature by repeatedly turning ON and performing cooling operation.

効に発揮できる。 During this period, when the relative humidity in the room becomes lower than a predetermined humidity due to the dehumidifying action of the air conditioner, the humidity controller 21 is turned on. By this ON operation, the solenoid valve 25 is opened and the humidifier 17 is activated, and the solenoid valve 11 is also opened and the branch pipe 10 is opened, so that a part of the gas discharged from the compressor 1 is transferred to the branch pipe. 1
0 and a branch pipe 8c, the refrigerant flows directly into one refrigerant passage 5c of the evaporator 5, and a heating section 12 is formed by the refrigerant passage 5c. As a result, the air sucked in from the suction port 14 is humidified by the humidifier 17, heated to a temperature higher than the dew point temperature by the heating action of the heating section 12, and then passed through the evaporator 5 to humidify the room. When the relative humidity in the room reaches a predetermined humidity or higher, the humidity controller 21 is turned off to stop the humidifying operation, and thereafter the above operation is repeated to keep the relative humidity in the room constant at approximately the predetermined humidity.
At this time, since the humidified air is heated above the dew point temperature in the heating section 12, no condensation occurs when passing through the evaporator 5, and the entire amount of water in the humidifier 17 is used for humidification. As a result, humidification efficiency can be greatly improved, and appropriate humidification efficiency can be effectively demonstrated.

はない。 During the humidifying operation, a portion of the gas discharged from the compressor 1 is supplied to the heating section 12, so the amount of refrigerant circulated in the cooling circuit is reduced, but the amount of decrease is small, so the cooling operation is stopped. It does not cause much trouble.

Since it can be formed with a simple structure of connecting to the flow divider pipe 8c of the flow divider 8, it has the advantage that the humidification efficiency can be easily improved at low cost.

ものである。 As explained above, according to the present invention, during humidification, a heating section is formed in a part of the evaporator through which gas discharged from the compressor flows, and the heating section allows the air humidified by the humidifier to flow through the heating section. Since the humidified air is heated above the dew point temperature and passed through the evaporator, no condensation occurs when the humidified air passes through the evaporator, and the humidification efficiency can be greatly improved. It has a humidifying effect and can effectively maintain constant temperature and humidity in air conditioning. Furthermore, since the heating section can be formed by simply connecting pipes, cost reduction and easy implementation can also be achieved.
