Stirling cycle heat engine adapted for use as space heating and/or air conditioners. One embodiment features a Stirling engine prime mover providing a hybrid Stirling machine. Another embodiment utilizes an electric drive motor as a prime mover and a final embodiment is an open drive Stirling thermal engine particularly adapted for automotive belt driven applications. Enhancements in performance are provided by using pressure ratios significantly lower than that ordinarily provided for Stirling cycle engines. Decreases in pressure ratios are provided by intentionally adding dead volume to the cycle and particularly adding this dead volume strategically in the regenerator of the device which has been found to provide performance benefits. The systems according to this invention can be used either as space heaters or air conditioners by appropriately directing heat absorbed and rejected from the heat exchangers of the device to the approrpriate environment.

A duplex Stirling cycle machine acting as a heat pump comprising: a Stirling engine having a plurality of pistons axially displaceable within parallel cylinders, said engine further having a swashplate rotatable about an axis of, rotation parallel to said cylinders and defining a plane inclined from said axis of rotation, said pistons connected to said swashplate via crossheads whereby axial displacement of said pistons is converted to rotation of said swashplate, and a Stirling cycle heat pump having a compression heat exchanger, an expansion heat exchanger and a regenerator with a plurality of pistons equal in number to said engine pistons and axially displaceable within cylinders which are oriented co-axially with said engine cylinders, said crossheads further connected to said heat pump pistons whereby said heat pump pistons move simultaneously with said engine pistons over an equal stroke distance.
