PERFORMANCE ANALYSIS AND MODELING OF A STATIC AIR-TO-WATER HEAT PUMP INTEGRATED IN A SINGLE-FAMILY DWELLING


This paper presents the results of the modeling of a static air-to-water heat pump
installed in a single-family dwelling in Belgium. We present a model combining the heat
pump and the house. Firstly, we develop sub-models for the heat pump itself, for the heating
floor and for the thermal behavior of the house. These sub-models have been validated
separately. The results of the heat pump model show good agreement with the experimental
results. For the model combining the heat pump and the heating floor, the simulation results
are as good as those obtained with the heat pump alone, thus validating the heating floor
model. The use of the whole system model shows higher discrepancies with experience
because the thermal model of the house is a single zone model. However, simulation results
over one year give good total values only 4 to 5% lower than experimental ones.
