REFRIGERATION CYCLE APPARATUS

摘要

A refrigeration cycle apparatus 1 includes a main circuit 10 connecting at least a compressor 11, a gas cooler 12, a pressure reducing device 13, and an evaporator 14 by a pipe and configured to circulate refrigerant transitioning to a supercritical state at a high-pressure side; a pressure detector configured to detect refrigerant pressure in a part of the main circuit 10 between the compressor 11 and the gas cooler 12; and a pulsation suppression unit configured to suppress pulsation of the refrigerant pressure to be detected by the pressure detector.
