Patent JP-H01285766-A (JP)
Title: Refrigerator
Inventor: SATO KOICHI
IPC: F25D16/00
Filed: 1988-05-13
Abstract: PURPOSE:To maintain the temperature in the refrigerator at that of the storage temperature of cooled objects while freezing the refrigerant by providing a refrigerator cooler and a refrigerant freezer, controlling the refrigerant supply to the refrigerator cooler by means of a valve, and regulating the control of the valve and compressor based on the refrigerator. CONSTITUTION:The interior space A of the refrigerator is cooled by a refrigerator cooler 17 as a refrigerant compressor 14 is operated and a valve 21 is opened. When the temperature in the refrigerator interior space A drops, the valve 21 is closed, and the cooling is performed solely by a freezer 18 for refrigerant 25. At the refrigerator interior space temperature of -0.5 deg.C, the compressor 14 is stopped, whereupon about 50% of refrigerant is frozen. At the refrigerator interior space temperature of 0.5 deg.C, the compressor 14 is started to resume the cooling of refrigerant 25, which is stopped at the refrigerator interior space of -0.5 deg.C. At this time, about 65% of refrigerant 25 is frozen, and, as the process advances, the operating time of the compressor 14 becomes shorter, while the cooled objects are stored without being frozen. This way, the refrigerant 25 can be frozen while the temperature of the refrigerator interior space A is maintained at a set level.
