Potential performance of an engine-driven Stirling heat pump
The potential of an engine-driven Stirling heat pump as an effective industrial heat recovery device is explored. A brief comparison is first made of the general performance of Stirling and Rankine refrigeration cycles. A simplified approach is given for the mathematical simulator of a Stirling cycle, which assumes a piston-displacer, valveless arrangement, and discontinuous operation. The relative energy use and COP for an idealized engine-driven Stirling heat pump were calculated as a function of system delivered temperature for source temperature between 150/sup 0/ and 300/sup 0/F, and comparisons are made with Rankine and Brayton systems. It is concluded with some moderations that the Stirling-type heat pumps operating at higher temperature levels and with larger temperature differences considered could be as viable as an equivalently operating Rankine heat pump.
