STEAM COMPRESSION TYPE REFRIGERATION CYCLE WITH EJECTOR

摘要

PROBLEM TO BE SOLVED: To provide a steam compression type refrigeration cycle with an ejector capable of increasing refrigerating effect of the refrigeration cycle by supercooling a high-pressure condensate by use of an intermediate port of a compressor and a built-in ejector cycle.;SOLUTION: This steam compression type refrigeration cycle with the ejector comprises the compressor 21 with the intermediate port, a condenser 22, an expansion valve 24a, and an evaporator 24. A supercooler 23 for cooling the high-pressure condensate led out of the condenser 22 is attached between the condenser 22 and the expansion valve 24a, and a cooling means of the supercooler 23 incorporates the ejector cycle 30. The ejector cycle 30 comprises the ejector 25, a gas-liquid separator 26, a throttle valve 26a, and a countercurrent type heat exchange path 23a.;COPYRIGHT: (C)2004,JPO
