Claims

[Scope of utility model registration request]

In the refrigerant circuit of an air conditioner, which consists of a compressor, a four-way valve, a three-way pipe, a condenser, a capillary tube, an evaporator, and an accumulator, the piping coming out of the four-way valve is guided around the accumulator, returned to the compressor, and then passed through the condenser. An air conditioner characterized in that a check valve between an inlet of the air conditioner is connected to a three-way pipe, and an outlet pipe of the three-way pipe during cooling is connected to a four-way valve.
