摘要： An ejector-type refrigerant cycle device includes: a first evaporator 15 that evaporates refrigerant flowing out of an ejector 14; a branch passage 17 that branches a flow of refrigerant between a radiator 13 and the ejector 14 and guides this flow of refrigerant to a vapor-phase refrigerant suction port 14c of the ejector 14; a throttling mechanism 18 disposed in the branch passage 17; and a second evaporator 19 disposed downstream of the throttling mechanism 18 with respect to the flow of refrigerant. The throttling mechanism 18 is constructed to be provided with a fully opening function, and to fully open the branch passage 17 when the second evaporator 19 is defrosted. Therefore, in an ejector-type refrigerant cycle device including multiple evaporators, the function of defrosting the evaporators can be carried out with a simple construction.

Accordingly, cooling capacity of the evaporator can be improved without lowering a density of refrigerant drawn into the compressor.

摘要： In an ejector cycle device having an ejector, an evaporator is arranged in a refrigerant branch passage connected to a refrigerant suction port of the ejector, an opening/closing member for opening and closing a refrigerant passage is disposed to prevent refrigerant from flowing into the evaporator, and a control unit intermittently controls operation of the compressor. In the ejector cycle device, the control unit brings the opening/closing member into a closing state in a time period for which the operation of the compressor is stopped. Accordingly, it can restrict liquid refrigerant from collecting in the evaporator while the compressor is stopped.
