An important potential application of the electrically driven Stirling cycle heat pump is in the field of industrial waste heat recovery. Here the temperatures and temperature lifts required are often outside the scope of existing types of heat pump. What has to be ascertained is whether the Stirling cycle heat pump can achieve a sufficiently high coefficient of performance. In the paper this question is examined by the use of a theoretical model. The model is first checked against measured results from an actual Stirling heat pump which has been built and tested, but which was of low COP. It is shown that for a temperature lift of WOK, it should be possible to construct a heat pump with a COP of about 3.5. It is also shown that under these conditions, the maximum attainable specific output of heat would approach 1 J/cycle cm3 of piston displacement.
