Résumé

In the present study, optimal water discharge temperature of heat pump for radiator heating is investigated, which is one of the main issues of air-to-water heat pump as the formal replacement of gas- or oil-fired boiler. To this end, thermal characteristics of radiator are investigated to find temperature required to match thermal loads of considered reference site at Paris, France. It is shown that water discharge temperature up to 70°C is required for the one-to-one replacement of current boilers. However, detailed numerical simulation showed that running heat pump at the same condition with boiler results in unacceptably low COP even with heat pump suited for high temperature. This issue is resolved by simple and novel water temperature control method, which results in the significant reduction in annual running cost and payback period.
