Title:
EVAPORATION PRESSURE REGULATING VALVE
Document Type and Number:
WIPO Patent Application WO/2023/276627
Kind Code:
A1
Abstract:
An evaporation pressure regulating valve (19) used for a refrigeration cycle (10) is disposed between evaporators (16, 18) and a compressor (11) in the refrigeration cycle (10). The evaporation pressure regulating valve (19) carries out regulation so that the refrigerant evaporation pressure in the evaporators (16, 18) is at least a predetermined reference evaporation pressure. The evaporation pressure regulating valve (19) is driven by an electric actuator (52). The evaporation pressure regulating valve (19) is configured such that the increase rate of the refrigerant flow rate with respect to the opening degree becomes larger as the opening degree increases.
