Summary

This article presents part of the results of a project devoted to the monitoring of 11 residential heat pumps used for space heating and for sanitary water heating. This project began in year 2000 and will be finished by the end of 2006. To date, 6 surveys are finished, and the authors present in this paper the results collected for 2 ground source-floor sink heat pumps. Both systems are common-type vapour-compression heat pumps and use ground (soil) as cold source, house floor as hot sink and R22 as refrigerant. Evaporation takes place in the soil and condensation in the floor (there are no secondary fluids and no auxiliary power consumption). The evaporator is placed at 60 cm deep in the backyard soil (75 m2 surface area) and the condenser is placed in the concrete ground floor of the house (3 coils of 70 m length). Small electrical heaters are placed in bathrooms and bedrooms.
