Abstract
A Stirling refrigerating system comprising a freezing chamber, a Stirling refrigerator, and a heat carrying means including a pipe arrangement thermally connected to a cooling portion of the Stirling refrigerator so as to carry low temperature heat of the cooling portion to the freezing chamber by means of a refrigerant, wherein when the Stirling refrigerator is driven, the refrigerant circulates in the freezing chamber and the cooling portion through the pipe arrangement. Thus, it is possible to obtain a Stirling refrigerating system in which not only it can cope with the current flon regulation but also it can use ethyl alcohol or the like as a refrigerant other than HCFC or HFC which may be subjected to legal regulation in the future, and it can increase the refrigerating capacity and improve the coefficient of performance in comparison with the existing system.
