<P>PROBLEM TO BE SOLVED: To easily execute a defrosting operation of an evaporator mounted at the refrigerant flowing-out side of an ejector in an ejector cycle comprising a plurality of the evaporators. <P>SOLUTION: The first evaporator 13 is mounted at the refrigerant flowing-out side of the ejector 12, the second evaporator 17 is mounted on a passage 15, 150 for a refrigerant sucked to a refrigerant suction opening 12c of the ejector 12, and a flow rate adjusting mechanism of the ejector 12 is controlled to a refrigerant flow rate state of more than a specific value in the defrosting operation of the first evaporator 13, and thus a cycle operation situation is controlled to temporarily increase a refrigerant evaporation temperature of the first evaporator 13 to a temperature zone higher than 0°C, while keeping the operating state of a compressor 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
