Abstract
When a compressor is stopped, a refrigerant passage in which refrigerant flows from a radiator to an evaporator is closed by a pressure control valve. Accordingly, even after the compressor is stopped, a high-pressure side pressure can be prevented from decreasing. This does not cause increased manufacturing cost of a supercritical refrigerating system.
