PROBLEM TO BE SOLVED: To provide an air conditioner in which the temperature of a refrigerating cycle can be rationalized. SOLUTION: A heat exchanger 1 for indoor unit, an expansion valve 5, a liquid tank 11, and a heat exchanger 7 for outdoor unit are coupled sequentially with a coupling pipe 17 for liquid pipe, and the heat exchanger 7 for outdoor unit, a four-way valve 10, a compressor 6, the four-way valve 10 and the heat exchanger 1 for indoor unit are coupled sequentially with a coupling pipe 18 for gas pipe to form a refrigerating cycle. A bypass line 20 bypassing the upper section of the liquid tank 11 and the inlet side of the heat exchanger 7 for outdoor unit are provided in parallel with the coupling pipe 17 for liquid pipe between the liquid tank 11 and the heat exchanger 7 for outdoor unit. A solenoid valve 21 is fixed to the way of the bypass line 20. The air conditioner comprises a thermistor 22 for detecting the temperature of the compressor 6, and a controller 12 for controlling the r.p.m. of a fan 9 for supplying air to the heat exchanger 7 for outdoor unit during heating operation based on the detection results of the thermistor 22. |
