Résumé

An experimental study of an air-to-water reversible heat pump unit was carried out using two different fin-and-tube heat exchanger "coil" designs and propane (R290) as the working fluid. The main aim of these tests was to search for optimized coil design concepts. The performance of the heat pump was evaluated for each coil design at different superheat conditions at the inlet of the compressor in both modes of operation: heating and cooling. COP in both modes of each heat pump unit using two different coil design are presented. Experimental measurements are compared against model predictions.
