<P>PROBLEM TO BE SOLVED: To provide an ejector type refrigerating cycle which simultaneously achieves both of improvement effect of nozzle efficiency and refrigerating capacity expansion effect of a suction-side evaporator, even when an operating condition is changed. <P>SOLUTION: The distributed-air amount of a first cooling fan 12a is controlled to adjust a degree of supercooling of an outlet refrigerant of a first radiator 12 for cooling a discharged refrigerant of a compressor 11 to be 3K or less. Further the flow of the outlet refrigerant of the first radiator 12 is branched, one of the branched refrigerants is allowed to flow into a nozzle portion 14a of the ejector 14, and the other is allowed to flow into a second radiator 16. Further the distributed-air amount of a second cooling fan 16a is controlled to adjust a degree of supercooling of an outlet refrigerant of the second radiator 16 to be 10K or more, and the refrigerant is allowed to flow into a suction-side evaporator 19. Thus both of the improvement effect of nozzle efficiency of the nozzle portion 14a and the refrigerating capacity expansion effect of the suction-side evaporator 19 are simultaneously achieved even when the operating condition is changed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
