Abstract:
1. A unit for a refrigerant cycle device, comprising: an ejector that has a nozzle part which decompresses refrigerant, and a refrigerant suction port from which refrigerant is drawn by a high-speed refrigerant flow jetted from the nozzle part, wherein the refrigerant jetted from the nozzle part and the refrigerant drawn from the refrigerant suction port are mixed and discharged from an outlet of the ejector; a first evaporator connected to the outlet of the ejector, the first evaporator having a heat exchanging part for evaporating the refrigerant flowing out of the outlet of the ejector; and a second evaporator connected to the refrigerant suction port of the ejector, the second evaporator having a heat exchanging part for evaporating the refrigerant to be drawn into the refrigerant suction port, wherein: the first evaporator and the second evaporator are arranged adjacent to each other to respectively have a first tank and a second tank adjacent to each other; one of the first tank and the second tank has a tank structure that is partitioned into a first space into which the refrigerant discharged from the outlet of the ejector flows, a second space and a third space; the second space and the third space are provided to distribute the refrigerant into and to collect the refrigerant from a plurality of refrigerant passages of the heat exchanging part of the one of the first tank and the second tank, respectively; the first space communicates directly with a tank space of the other one of the first tank and the second tank such that the refrigerant flowing out of the ejector flows into the tank space of the other one of the first tank and the second tank via the first space; and the refrigerant suction port of the ejector communicates with the third space into which the refrigerant passing through the refrigerant passages of the heat exchanging part of the one of the first tank and the second tank is collected.
