Title:
EJECTOR-TYPE REFRIGERATION CYCLE
Document Type and Number:
WIPO Patent Application WO/2016/031157
Kind Code:
A1
Abstract:
An ejector-type refrigeration cycle (10) equipped with an ejector module (13) in which a gas-liquid separation device is integrally formed. The length of an intake pipe (15c) connecting a gas-phase refrigerant outflow opening (31d) of the ejector module (13) and an intake port of a compressor (11) is less than length of an outlet pipe (15e) connecting a refrigerant outflow port of an evaporator (14) and a refrigerant suction port (31b) of the ejector module (13). Thus, the pressure loss occurring when the refrigerant passes through the intake pipe (15c) can be made lower than the pressure loss occurring when the refrigerant passes through the outlet pipe (15e). Therefore, it is possible to prevent a large reduction in the refrigerant pressure immediately before being drawn into the compressor (11), and to enable an adequate effect of improving the COP in an ejector-type refrigeration cycle to be obtained.
