KUBOTA has been developing a gas engine-driven Stirling heat pump (STHP) system using both engine shaft power and engine exhaust heat. This STHP is a heat-assisted Stirling heat pump and is constructed as two sets of three-cylinder machines, each a combination of two Stirling sub-systems; one a power producer and one a heat pump. This paper describes the system schematics and the system performances. The tests were performed at concurrent cooling and heating operations, fueling methanol reformed gas (CO+2H_2). A cooling capacity of 4.8kW at 280K and a heating capacity of 9.1kW at 318K were attained, and the total COP was reached to 2.1 at the input fuel basis. It was shown by the performance tests that the STHP had high COP and could construct a high performance CFC-free heat pump system.
