Title: Refrigeration storage
Inventor: HARA TOSHIAKI
IPC: F25D11/00
Filed: 2003-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To further save electric power by minimizing the time for operating a refrigerating unit as required.  <P>SOLUTION: In a time zone for cold keeping operation where a set temperature is high (15°C), when the outside temperature is low, the refrigerating unit (a compressor) may not be operated for a long time. As a result, humidity in the storage is increased in the meantime to produce an easily molding condition. It is effective to decrease the humidity in the storage with forcible refrigerating operation (a set temperature of 3°C). However, the forcible refrigerating operation (one hour) is only permitted after continuously stopping the refrigerating unit for a preset time (four hours) since entering the time zone for the cold insulating operation. In other words, when the refrigerating unit is operated therebefore for cooling down to the set temperature (15°C), the humidity in the storage is also decreased accordingly and so risky operation of the refrigerating unit is avoided.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
