FREE PISTON TYPE STIRLING CYCLE REFRIGERATING SYSTEM AND FREE PISTON TYPE STIRLING CYCLE REFRIGERATING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a free piston type Stirling cycle refrigerating system capable of uniformly cooling the whole cooled object, and a free piston type Stirling cycle refrigerating machine capable of reducing lowering of cooling capacity.;SOLUTION: This free piston type Stirling cycle refrigerating machine 1 is provides with an auxiliary tank 20 filled with a working medium of high pressure, and communicated with a refrigerating machine main body casing 2 of the refrigerator 1 through piping 21. As a pressure of the working medium in the refrigerating machine main body casing 2 is lowered, and the efficiency in absorbing and radiating heat is lowered, which causes deterioration of cooling efficiency, when a heat absorbing portion 13 is sufficiently cooled during the operation of the refrigerating machine 1, the lowering of the pressure can be prevented by sending the working medium in the refrigerating machine main body casing 2 from the auxiliary tank 20 filled with the working medium of high pressure, and the deterioration of cooling efficiency can be prevented. Further in the refrigerating system for cooling one cooled object 5 by using the plurality of free piston type Stirling cycle refrigerating machines, the cooled object 5 can be efficiently cooled.;COPYRIGHT: (C)2007,JPO&INPIT
