<P>PROBLEM TO BE SOLVED: To provide an ejector type refrigerating cycle capable of improving a defrosting capacity of a second evaporator. <P>SOLUTION: In this ejector type refrigerating cycle 10 where the refrigerant flow is branched at a branching portion 23 at a downstream side of an ejector 13, one of the branched refrigerants is allowed to be sucked to a compressor 11, the other refrigerant is allowed to be sucked to a refrigerant suction opening 13b of the ejector 13, a first evaporator 14 is disposed between the refrigerant branching portion 23 and the compressor 11, and the second evaporator 15 is disposed between the refrigerant branching portion 23 and the refrigerant suction opening 13b, the first and second evaporators 14, 15 are integrated. The defrosting capacity of the second evaporator 15 can be improved, as the heat of the refrigerant is transmitted from the first evaporator 14 to the second evaporator 15 when the refrigerant of a defrostable temperature is supplied to the downstream side of the ejector 13 by increasing an opening of a nozzle portion 13a of the ejector 13 in the defrosting operation of the first and second evaporators 14, 15 in comparison with that in a refrigerating operation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
