Phase I-B development of kinematic Stirling/Rankine commercial gas-fired heat-pump system. Annual report, September 1983-December 1984

Abstract

The goal of this project is to develop a commercial-size Stirling engine-driven gas heat pump with a cooling capacity of 10 ton, and a COP (heating) of 1.8 and COP (cooling) of 1.1. The project is a multi-phase development with commercialization planned for 1989. A piston-type open-shaft refrigeration compressor was selected as the best match for the engine. Both the engine and compressor were tested and characterized by performance maps, and the experimental heat-pump systems designed. The manufacturer continued to focus on improving the Stirling-engine performance and reliability for the gas heat pump application.
