A preliminary design for a 2nd generation, gas-fired free-piston Stirling engine driven heat pump has been developed which incorporates a linear magnetic coupling to drive the refrigerant compressor piston. The Mark 2 machine is intended for the residential heat pump market and has 3 Ton cooling capacity. The new heat pump is an evolutionary design based on the Mark 1 free-piston machine which was successfully developed and independently tested by a major heat pump/air conditioning manufacturer. This paper briefly describes test results that were obtained with the Mark 1 machine and then presents the design and operating cost analysis for the Mark 2 heat pump. Operating costs by month are given for both Chicago and Atlanta. A summary of the manufacturing cost estimates obtained from Pioneer Engineering and Manufacturing Company (PEM) are also given. 9 figs., 3 tabs.
