PORTABLE REFRIGERATOR, REFRIGERATOR WITH DEEP FREEZER AND MANUFACTURE THEREOF

摘要

PURPOSE: To exist mixed various foods by cooling refrigerant gas by a cold heat storage material and chemical reaction heat to liquefy it, vaporizing the liquefied gas by a heat exchanger of freezing and cold storage chambers, and cooling it by the heat of vaporization. ;CONSTITUTION: Liquid refrigerant gas in a first condenser 9 absorbs heat in a refrigerator by a heat absorbing plate 9-1 in close contact with first and second condensers 9, 10 to be partly evaporated, the pressures of the condensers 9, 10 are raised, and liquid refrigerant gas G in the condenser 9 is press injected in a heat exchanger 4 and a freezing heat exchanger 5-1 via a capillary 23. The gas G5 fed to the exchanger 5 and the exchanger 5-1 is lowered to a lower part while evaporating G2, G3, heat exchanged, returned to the outer vessel of a container 3 via a pipe 28, and liquefied. Then, it can cool the refrigerator and the deep freezer. Thus, various foods such as fish, fruits, sandwiches, etc., can be mixed, thereby enlarging an available range.;COPYRIGHT: (C)1996,JPO
