<P>PROBLEM TO BE SOLVED: To obtain a refrigerating cycle device capable of transferring to an ejector cycle for a short time without declining performance after defrosting operation. <P>SOLUTION: In the refrigerating cycle device 100, a compressor 5, a condenser 6, a gas liquid separator 12, an evaporator 14 and an ejector 11 including a drive inflow port 11a to which a liquid refrigerant from the condenser 6 is made to flow in and a suction inflow port 11b sucking a refrigerant from the evaporator 14 are interconnected by refrigerant piping, so as to form the ejector cycle. The refrigerating cycle device 100 includes a first on-off valve 9, a first flow regulating valve 10, a second on-off valve 16, a third on-off valve 18, a second flow regulating valve 19 and a control means 30 for controlling the first on-off valve 9, the first flow regulating valve 10, the second on-off valve 16, the third on-off valve 18 and the second flow regulating valve 19 to switch a flow passage of a refrigerant. The control means 30 forms a refrigerant flow passage for circulating the liquid refrigerant in the evaporator 14 after the defrosting operation for eliminating the frost formation state of the evaporator 14 is completed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
