Supercritical refrigerating system

Abstract

When a compressor (1) is stopped, a refrigerant passage (6a) in which refrigerant flows from a radiator (2) to an evaporator (4) is closed by a pressure control valve (3). Accordingly, even after the compressor (1) is stopped, a high-pressure side pressure can be prevented from decreasing. This does not cause increased manufacturing cost of a supercritical refrigerating system.
