PROBLEM TO BE SOLVED: To keep a temperature of a heat exchanger within a range of certain specific temperatures, to prevent the breakage of a compressor caused by the rise of suction pressure of the compressor, and to effectively control the frosting on an apparatus without impairing amenity. SOLUTION: When a temperature of an indoor heat exchanger 13 of an air conditioner is lowered, the operation is performed in a state that an operation frequency of a compressor 2 is lowered to increase the temperature to be higher than a temperature of an indoor heat exchanger temperature setting storing device 1. When a value of a suction pressure detecting device 10 of the compressor 2 is higher than a value of a suction pressure setting storing device 29, a motor-driven expansion valve 9 mounted in a suction pipe 8 is controlled in the closing direction to be over a valve opening degree of the motor-driven expansion valve 9.
