High efficiency refrigerator

摘要

A thermal storage container is coupled to a pump for circulating cooled liquid from the thermal storage container in at least one of two circuits. One circuit includes a heat exchanger coupled to the fresh food evaporator for assisting in cooling the fresh food section of the refrigerator or for chilling the liquid. Another circuit includes a sub-cooler between the compressor and condenser for cooling the hot gas output from the compressor before entering the condenser, thereby increasing the efficiency of the system. A three-way valve is coupled from the output pump to couple the stored coolant selectively to one or the other or both of the coolant circuits.
