Abstract

An air-conditioner includes a small-capacity compressor and a large-capacity compressor for compressing a refrigerant to a high temperature high pressure gaseous refrigerant; a valve for connecting a suction opening of a refrigerant channel of the large-capacity compressor and a discharge passage of a refrigerant channel of the large-capacity compressor; and a controller for controlling the small-capacity compressor, the large-capacity compressor and the valve.
