Stirling cycle heat pump for heating and/or cooling systems
Abstract
This patent describes a duplex Stirling cycle machine acting as a heat pump. It comprises: a Stirling engine having pistons axially displaceable within parallel cylinders, the engine further having a swashplate rotatable about an axis of, rotation parallel to the cylinders and defining a plane inclined from the axis of rotation. The pistons connected to the swashplate via crossheads whereby axial displacement of the pistons is converted to rotation of the swashplate, and a Stirling cycle heat pump having a compression heat exchanger, an expansion heat exchanger and a regenerator with pistons equal in number to the engine pistons and axially displaceable within cylinders which are oriented co-axially with the engine cylinders. The crossheads further connected to the heat pump pistons whereby the heat pump pistons move simultaneously with the engine pistons over an equal stroke distance.
