Filed: 1998-11-28
Abstract: PURPOSE: A refrigerator is provided to promote the increase of sufficient cooling efficiency even with a small amount of capacity of a compressor and to prevent indoor temperature of an apparatus room from rising. CONSTITUTION: In a refrigerator, a part of cold air around evaporators is accumulated by first and second cold storage plates(400,500) in a cooling cycle of the evaporators and a compressor(141). Therefore, the refrigerator obtains sufficient cooling efficiency by using the accumulated cold air with the compressor having a small amount of capacity. Also, the food is effectively frozen and refrigerated by circulating the cold air through first and second ventilating fans(600,700) in a freezing chamber(120) and a refrigerating chamber(130).
