More Information
Summary:A vapor compression refrigerating cycle apparatus includes a compressor, a radiator, a first decompressing device, a second decompressing device, a flow distributor, an ejector, and a suction-side evaporator. The vapor compression refrigerating cycle apparatus is configured such that refrigerant pressure (P0) at an inlet of the first decompressing device, refrigerant pressure (P) at an inlet of a nozzle portion of the ejector, refrigerant pressure (P2) at an outlet of the nozzle portion satisfy a pressure relationship of 0.1x(P0-P2)<=(P0-P)<=0.6x(P0-P2). Alternative to or in addition to the pressure relationship, the vapor compression refrigerating cycle apparatus is configured such that a dryness of refrigerant at the inlet of the nozzle portion is in a range between 0.003 and 0.14.
