Abstract
In a refrigerant evaporator constructed by a plurality of heat-exchanging units, a bypass passage to bypass at least one of the plurality of heat-exchanging units is provided, and the refrigerant passage area thereof is set to be less than that of a refrigerant passage in the heat exchanging units. Thus, a part of the liquid refrigerant can bypass the heat-exchanging units, and the liquid refrigerant quickly flows out of the evaporator, thereby shortening the time for returning the liquid refrigerant to the compressor right after the refrigerating cycle starts.
