<P>PROBLEM TO BE SOLVED: To provide an ejector-type refrigeration cycle using a second ejector which can be easily manufactured. <P>SOLUTION: This ejector-type refrigeration cycle includes: first and second ejectors 15 and 24 for sucking refrigerant from a refrigerant suction openings 15b, 24b by means of high-speed refrigerant flows ejected from nozzle sections 15a, 24a; a first suction-side evaporator 19 connected to the refrigerant suction opening 15b of the first ejector 15; and a second suction-side evaporator 27 connected to the refrigerant suction opening 24b of the second ejector 24. A flow rate of the refrigerant in the second ejector 24 is less than a flow rate of the refrigerant in the first ejector 15. The refrigerant branched at a branch section Z2 located downstream of a heat radiator 13 and upstream of the first ejector 15, flows into the second ejector 24, and the refrigerant branched on a downstream side of the second ejector 24 flows into the second suction-side evaporator 27. <P>COPYRIGHT: (C)2013,JPO&INPIT |
