PROBLEM TO BE SOLVED: To provide an air conditioner capable of being used as a special purpose cold air blower or a special purpose dehumidifier in a cold air dehumidifier using a refrigerating cycle. SOLUTION: A first heat exchanger 2 in which high temperature and high pressure refrigerant gas discharged from a compressor 1 is fed is provided. A four-way valve 3 having a discharge side of the exchanger 2 used as a refrigerant inlet 3a and a refrigerant outlet 3b connected to a suction side of the compressor 1 is provided. A second heat exchanger 4, a capillary 5 and a third heat exchanger 6 are connected in series between a first switching port 3c and a second switching port 3d of the valve 3. The exchangers 2, 4 are connected to a channel of an exhaust supply fan 8. The exchanger 3 is disposed at a channel of an indoor supply fan 7, and an air outlet of the fan 7 is provided on a front surface of a frame of the air conditioner. The exchangers 4, 6 are functioned as condensers or evaporators by switching the valve 3, thereby forming operating states of a special purpose cold air blower and a special purpose dehumidifier. |
