EJECTOR-TYPE REFRIGERATION CYCLE, AND EJECTOR MODULE

WIPO Patent Application WO/2019/155806

A1

This ejector-type refrigeration cycle comprises: a compressor (11); a heat radiator (12); an ejector (14); a suction-side pressure reduction unit (15, 15a, 15b, 15c, 15d, 15e, 60, 60a); and a suction-side evaporator (19). The compressor compresses and discharges a refrigerant. The heat radiator radiates heat from the refrigerant discharged from the compressor. The ejector suctions the refrigerant from a refrigerant suction port (14c) by a suction action of an injection refrigerant that is injected from a nozzle unit (14a) which reduces the pressure of the refrigerant flowing out from the heat radiator, and the ejector increases the pressure of a mixed refrigerant of the injection refrigerant and a suction refrigerant that was suctioned from the refrigerant suction port. The suction-side pressure reduction unit reduces the pressure of the refrigerant. The suction-side evaporator evaporates the refrigerant that was pressure-reduced by the suction-side pressure reduction unit and causes the refrigerant to flow out to the refrigerant suction port side. The suction-side pressure reduction unit changes the degree of opening on the basis of an inlet-side pressure (Pni), which is the pressure of the refrigerant flowing into the nozzle unit.
