Claims

[Scope of utility model registration request]

In an air conditioner configured by sequentially connecting a compressor, a four-way valve, an outdoor heat exchanger, an electric expansion valve, and an indoor heat exchanger to configure a refrigeration cycle capable of air-conditioning operation, the throttle of the electric expansion valve The air conditioner is characterized in that its operation is controlled by the temperature on the suction side of the compressor during cooling operation, and by the difference between the suction side temperature of the compressor and the heat exchanger temperature table of the outdoor heat exchanger during heating operation. harmonization device.
