Abstract
A refrigerator comprises a refrigerating cycle in which a refrigerant is charged and which includes a cooler for a freezing compartment, a closed loop which is branched from the refrigerating cycle and includes a cooler for a refrigerating compartment, and a heating device provided in the closed loop which supplies the refrigerant to the closed loop by means of vapor bubble pumping action, to thereby control the refrigerant flow in the closed loop.
