PURPOSE:To automatically switch between supply of cold air and dehumidification without reducing cooling function by so connecting a cold air duct and a hot air duct through a connection tube as to suck hot air, and providing a valve which is opened only by a special pressure relationship in the tube. CONSTITUTION:A cold air duct 1 is provided at the top of a housing 40, and a cold air fan is contained therein. Air flow is guided into the duct 1 through an evaporator 32 provided near an atmospheric air inlet, thermally exchanged by an evaporator 32, and cold air is fed from a cold air diffuser 41. A hot air fan 4 is contained in a hot air duct 3, the air is sucked through a condenser 31 to be discharged from a hot air diffuser 5. The ducts 3, 1 are so connected by a connection tube 7 as to suck the hot air. A valve 8 is provided at the end near the duct 1 of the tube 7, and so formed as to open in case of Pc<Ph, where Pc is pressure in the duct 1 and Ph is pressure in the duct 3. |
