Stirling cycle air conditioning system
This patent describes improvement in a closed loop cooling system using a circulating coolant fluid as a heat transfer medium and including a first heat exchanger means for cooling a selected area, means for circulating the coolant to the heat exchanger and a Stirling cycle cooler having a second heat exchanger means for removing heat from the recirculating heat laden coolant. The improvement comprises, a hermetically sealed Stirling cycle cooler employing an environmentally safe non-freon base coolant and having a magnetic clutch for coupling a pulley driven power thereto, a first magnetic coupling means for magnetically coupling shaft power of the driven pulley to a first end of a crankshaft of the Stirling cycle cooler through a first end-wall of the hermetically sealed cooler and a second magnetic coupling means for magnetically coupling a second end of the cooler crankshaft through a second end-wall of the hermetically sealed cooler to an impeller pump for pumping the coolant through the closed loop system, whereby the Stirling cycle cooler and the closed loop cooling system constitute two separate hermetically sealed systems for effectively eliminating refrigerant coolant leakage through housing shaft seals.
