    摘要: In a refrigerant cycle device having an ejector, a branch portion for branching a flow of refrigerant flowing out of the ejector into at least a first refrigerant stream and a second refrigerant stream is located. A first evaporator for evaporating the refrigerant of the first refrigerant stream is located to allow the refrigerant to flow to a suction side of the compressor, and a second evaporator for evaporating the refrigerant of the second refrigerant stream is located to allow the refrigerant to flow to an upstream side of a refrigerant suction port of the ejector. In addition, the branch portion is located to maintain a dynamic pressure of the refrigerant flowing out of the ejector, and the second evaporator is connected to the branch portion in a range where the dynamic pressure can be applied to an inside of the second evaporator.

    摘要: An ejector cycle with an ejector includes a nozzle for decompressing refrigerant. A receiver for storing refrigerant is disposed at a refrigerant outlet side of a condenser. A bypass passage and a switching valve for opening and closing the bypass passage are provided so that high-temperature refrigerant discharged from a compressor is introduced into an evaporator while bypassing the condenser in a defrosting operation. When the defrosting operation is set, the switching valve is opened while a fan for blowing cool air to the condenser is operated. A part of refrigerant discharged from the compressor flows into the evaporator to remove frost on a surface of the evaporator.

    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.
