<P>PROBLEM TO BE SOLVED: To attain a defrost function of an evaporator by a simple construction in an ejector type refrigeration cycle including a plurality of evaporators. <P>SOLUTION: The ejector type refrigeration cycle comprises a first evaporator 15 for evaporating a refrigerant flowing out from an ejector 14, a branch passage 17 for branching 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 in the downstream of the refrigerant flow from 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. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
