|1. (WO2018198609) EJECTOR REFRIGERATION CYCLE|
|Title:||EJECTOR REFRIGERATION CYCLE|
In the present invention, an enthalpy raising unit that raises the enthalpy of a refrigerant flowing into a nozzle (20a) of an ejector (20) is formed of: a nozzle-side internal heat exchanger (13) that causes heat exchange between a refrigerant flowing from a radiator (12) and the refrigerant flowing into the nozzle (20a) of the ejector (20); and an intake-side internal heat exchanger (17) that causes heat exchange between the refrigerant discharged from the radiator (12) and a refrigerant taken into a refrigerant intake opening (20c) of the ejector (20). Due to this configuration, a sprayed refrigerant that is sprayed from the nozzle (20a) becomes a superheated gas phase refrigerant, and the amount of recovered energy is increased to sufficiently improve the coefficient of performance of an ejector refrigeration cycle (10).
