Abstract
In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a control unit controls an air blowing amount of an evaporator fan so that a flow speed of refrigerant flowing in an evaporator becomes in a predetermined flow speed range. Therefore, it can prevent a large amount of lubrication oil from staying in the evaporator, and thereby the lubrication oil can sufficiently returns to a compressor. For example, the control unit includes a determining means for determining the predetermined flow speed range based on at least one of an atmosphere temperature of a condenser, a temperature of air supplied to the evaporator and a flow amount of refrigerant discharged from the compressor.
