PURPOSE:To reduce the compressor power consumption by closing a water valve when a temperature control operation unit is operated to the cooler side and no defumidifying signal is transmitted and opening it in other cases. CONSTITUTION:When a temperature control operation unit 19 is operated to the cooler side, a microswitch 18 is turned on and an ON signal is fed to a control circuit 15. On the otherhand, a humidity sensor 21 detects the car room humidity and feeds a humidity signal to the control circuit 15, which performs air conditioning and dehumidification based on it. When dehumidification is not required and an ON signal is fed from a microswitch 18, a close signal is fed to a water valve 4 to close it. In other cases, the water valve 4 is kept open. According to this constituion, the compressor power consumption can be reduced without impairing the temperature control and dehumidification function. |
