Abstract
An energy efficient frost free refrigerator having a cooling compartment a freezing compartment and a single refrigerating element is defrostable during refrigeration off cycles by the circulation of air within the refrigerator. The refrigerating element is physically located above the freezing compartment. Defrost of the refrigerator is accomplished without objectionable defrost of what is in the freezing compartment and without the need to introduce generated heat to effect the defrost. The configuration of the elements protects what is frozen within a pool of freezing air, protected against defrost. A circulating fan may be used to implement the process. The configuration of the refrigerator of the present invention enables an economy of energy use and construction cost.
