Patent JP-2002277144-A (JP)
Title: Refrigerator
Inventor: TAKAICHI KENJI
IPC: F25D21/08
Filed: 2001-03-15
Abstract: PROBLEM TO BE SOLVED: To avoid a danger even when holes are opened due to the breakage or corrosion of piping upon defrosting in a refrigerating cycle using a combustible refrigerant. SOLUTION: Only during defrosting, components having a high boiling point such as hydrocarbon, ether or ketone, etc., are added from a storage device 38 to the ordinary combustible refrigerant to lower the pressure of the refrigerant piping 32. A pressure detecting means 34 or a temperature detecting means controls the pressure of the piping 32 in the refrigerating cycle not to be atmospheric pressure or higher. Thus, even when a failure is generated in the piping 32, the combustible refrigerant does not leak. Further, during an ordinary cooling operation, the operation is carried out by the ordinary combustible refrigerant, so that the refrigerant is suitably compressed without excessively lowering the pressure of the refrigerating cycle.
