ABSTRACT:
An object of the present invention is to provide a refrigerant cycle apparatus which can reduce a production cost while hastening equalization of pressure in a refrigerant circuit after a compressor is stopped, the apparatus comprises a bypass circuit which causes an intermediate-pressure area to communicate with a low-pressure side of a refrigerant circuit, a valve device provided to this bypass circuit and a control device which controls opening/closing of this valve device, and the control device constantly closes the valve device but opens it in order to release a flow path of the bypass circuit concurrently with the stop of the compressor.
