Performance evaluation of an air-to-air heat pump coupled with temperate air-sources integrated into a dwelling

Abstract : An inverter-driven air-to-air heat pump model has been developped and implemented in the thermal simulation tool COMFIE, in order to compare the seasonal performance of a variable capacity air-to-air heat pump coupled with temperate air sources (crawlspace, attic, sunspace, heat recovery ventilation, earth-to-air heat exchanger) with the performance of a conventionally installed heat pump. The empirical model of the heat pump is presented in this paper, including full-load and part-load model at rating and non rating conditions, and also frosting conditions.
Several coupling configurations are studied and applied on a case study: a French typical residential house. The influence of the climatic region is evaluated, giving indications on energy saving using such systems.
