Abstract

SYNOPSIS A system is described for low-temperature heat generation for space heating envisaging the adoption of an organic fluid external combustion engine as the direct drive for a heat pump. Waste heat from the engine condenser contributes a substantial fraction of the overall heat output. Progress in experimental work to ascertain the suitability of organic fluids to operate at comparatively high temperature without appreciable decomposition or corrosive action on materials is reported. Results are given of a computation program predicting the performance of systems of various capacity. For the examples considered yearly fuel consumption was calculated to range between 41 and 48% of that of a conventional plant.
