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.

摘要: An air conditioner with an ejector includes first and second interior heat exchangers for performing heat-exchange between refrigerant and air to be blown into a compartment. The second interior heat exchanger is disposed at a downstream air side of the first interior heat exchanger, and a decompression valve for decompressing refrigerant in a dehumidifying-heating operation is disposed in a refrigerant passage connecting the first and second interior heat exchangers. In a cooling operation, the first and second interior heat exchanger are used as evaporators. On the other hand, in the dehumidifying-heating operation, refrigerant decompressed in the decompression valve is evaporated in the first interior heat exchanger while bypassing a nozzle of the ejector, and refrigerant is radiated in the second interior heat exchanger.
