Abstract

A vapor-compression refrigerant cycle device includes an ejector, a first evaporator for evaporating refrigerant flowing out of a pressure-increasing portion of the ejector, a second evaporator for evaporating refrigerant to be drawn into a refrigerant suction port of the ejector. In the refrigerant cycle device, a refrigerant suction pipe is connected to a refrigerant outlet of the second evaporator and the refrigerant suction port of the ejector, and the surface of the refrigerant suction pipe is covered by an insulating member. Furthermore, the ejector, the first evaporator, the second evaporator and the refrigerant suction pipe are arranged in a passenger compartment of the vehicle.
