<P>PROBLEM TO BE SOLVED: To enhance the cycle efficiency of a refrigeration cycle device which can cool a plurality of cooled spaces different in temperature range without the need of complicated control. <P>SOLUTION: A flow ratio of a flow rate of refrigerant flowing from a branch 13 into a nozzle 14a of an ejector 14 and a flow rate of a refrigerant flowing from the branch 13 into a suction-side evaporator 21 is set in advance to a value which achieves high cycle efficiency. In addition, the heat exchange core of an outflow-side evaporator 16 that evaporates the refrigerant flowing from a diffuser 14d of the ejector 14 is divided into a first core 16a which exhibits a cooling capacity for cooling a chilling chamber Ci, and a second core 16b which exhibits a cooling capacity for cooling a freezer chamber Fr. Therefore, the chilling chamber Ci is cooled with the cooling capacity exhibited by the first core 16a, and the freezer chamber Fr is cooled with the cooling capacity exhibited by the second core 16b and the suction-side evaporator 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
