Refrigerator having temperature-responsive control means for combined direct and fan-cooled operation

摘要

A refrigerator with a freezing chamber and a cold chamber, wherein the freezing chamber is cooled rapidly by a main, fan-type, cooling system and a secondary, direct-type, cooling system. The secondary cooling system includes a box-like cooler having a projecting plate for placing food products thereon to provide uniform cooling within the freezing chamber. The refrigerator compressor is controlled in accordance with the temperature of the freezing chamber so as to be efficiently operated in the freezing cycle. Gas coolant is directed via control valves in accordance with the temperature of the freezing and cold chambers.
