Title:
EJECTOR TYPE REFRIGERATION CYCLE
Document Type and Number:
WIPO Patent Application WO/2006/033378
Kind Code:
A1
Abstract:
An ejector type refrigeration cycle, comprising a first evaporator (15) for evaporating refrigerant flowing out from an ejector (14), a branch passage (17) for bifurcating a refrigerant flow between a radiator (13) and the ejector (14) and introducing the refrigerant flow to a gas phase refrigerant suction opening (14c) of the ejector (14), a restriction mechanism (18) provided in the branch passage (17), and a second evaporator (19) installed on the more downstream side of the refrigerant flow than the restriction mechanism (18). The restriction mechanism (18) is provided with a function for fully opening the branch passage (17) at the time of defrosting the second evaporator (19). In the ejector type refrigeration cycle comprising a plurality of evaporators, a defrost function of the evaporator can be realized through the simple construction.
