Abstract
An ejector cycle with an ejector includes a nozzle for decompressing refrigerant. A receiver for storing refrigerant is disposed at a refrigerant outlet side of a condenser. A bypass passage and a switching valve for opening and closing the bypass passage are provided so that high-temperature refrigerant discharged from a compressor is introduced into an evaporator while bypassing the condenser in a defrosting operation. When the defrosting operation is set, the switching valve is opened while a fan for blowing cool air to the condenser is operated. A part of refrigerant discharged from the compressor flows into the evaporator to remove frost on a surface of the evaporator.
