Abstract

A refrigerator includes a heat-insulating housing having compartments separated from one another and each having a different temperature, evaporators each cooling one of the compartments with a refrigerant, each compartment having a different refrigerating capacity, throttles each connected upstream of an evaporator, a refrigerant compressor having a suction side connected to a refrigerant collector, and at least one activator connected to the evaporators, the activator positively and separately controlling circulation of the refrigerant through the evaporators. The compressor is connected to the throttles and evaporators for circulating the refrigerant. One evaporator has a higher capacity and a refrigerant routing portion with a refrigerant reception volume. The collector collects an amount of refrigerant when the compressor is in the standstill phase. More than a majority of the reception volume of the refrigerant routing portion is filled with the refrigerant in the standstill phase of the compressor.
