Abstract
The authors had developed a Stirling cooler and cooling unit (single Stirling cooling unit). In addtion, A double Stirling cooling unit installing two Stirling coolers has been developed to aim at increasing in the cooling capacity of unit. This paper presents a tandem type Stirling cooler which is built up by connecting two Stirling coolers with coupling the crank shafts directly. The cooling unit with the tandem type Stirling cooler is superior to the double Stirling cooling unit, because motor input decreases and buffer tank is not necessary. So the tandem Stirling cooler could be very useful to make refrigeration systems higher efficiency, more compact and cost down.
