Abstract
An evaporator unit includes an ejector, an upwind side heat exchanger for evaporating a discharge side refrigerant flowing from the ejector, and a downwind side heat exchanger for evaporating a suction side refrigerant to be drawn into the ejector. The ejector has a nozzle for decompressing refrigerant, and a refrigerant suction port, from which refrigerant is drawn by a high-speed flow of refrigerant jetted from the nozzle. The upwind side heat exchanger has a refrigerant superheat area, which is offset from a refrigerant superheat area of the downwind side heat exchanger in a direction perpendicular to an air flow to be cooled.
