Claims

[Claims for Utility Model Registration] A first refrigeration cycle includes a first evaporator, a first capillary tube, a compressor, a condenser, and an accumulator; A second refrigeration cycle including a second evaporator and a second capillary tube and having a higher refrigerating capacity than the first refrigeration cycle is provided, and an inlet for introducing the refrigerant into the accumulator body is provided in an intermediate portion of the accumulator body. A refrigerant outlet is provided in the upper part of the accumulator body,
A refrigeration cycle system for a refrigerator in which both the refrigeration cycles are made switchable by switching means provided upstream of the first and second evaporators, and the refrigeration capacity is switched. A refrigeration cycle system for a refrigerator, characterized in that a return pipe is connected to an upper part of the accumulator main body.
