Summary

Geothermal heat pump systems (GHPSs) are more energy efficient than traditional HVAC systems for space heating and cooling applications in buildings. In this paper, the thermal performance of a vertical closed-loop GHPS installed in a single-family residential building located in Innisfil (80 km north of Toronto, Canada) is tested, analyzed and evaluated when operated in the cooling mode throughout the hottest week of the year. Results show that the highest and lowest coefficient of performances (COPs) of the GHPS are 11.1 and 10.7, respectively, and variation of outdoor air temperature has no influence on the COP of the GHPS. The average temperatures of water leaving and entering the ground loop are 13.0ºC and 15.4ºC, respectively. Further, the average evaporator and condenser temperatures are 4.6ºC and 17.9ºC, respectively. It is concluded that compared to conventional air-source heat pumps (ASHPs), the tested GHPS can significantly reduce space cooling energy consumption in Canadian residential buildings.
