。The heat of the refrigerant gas compressed by the compressor is dissipated in the condenser, and the high-temperature, high-pressure liquid refrigerant is temporarily stored in the liquid receiver, and then the pressure is reduced by the expansion valve and the atomized refrigerant is purified. In a refrigeration cycle in which heat is exchanged in a generator and refrigerant is circulated to a compressor again via an evaporation pressure controller provided on the discharge side of an evaporator, the evaporation pressure controller and an expansion valve are connected. The outlet of the pressure equalization pipe is provided on the suction side and the discharge side of the evaporation pressure controller, and a three-way switching valve that opens and closes depending on the pressure difference between the suction side and the discharge side is installed in the middle of the equalization pipe. Characteristics of the evaporation pressure control device in the refrigeration cycle.
