| Abstract | An experimental geothermal heat pump system for space cooling was installed in Kamphaengphet, Thailand, in October 2006 and was operated for 17 months. Temeprature changes in the heat exchange borehole were measured through the period to evaluate the subsurface thermal properties and effects of short and long term operation of the system onto subsurface thermal environment. Temperatures of secondary fluid, room and atmosphare, were also measured through the period. The electricity comsumption and flow rate of secondary fluid were also measured to evaluate coefficient of performance (COP) of the system. The results of temperature measurements and calculation of system performances will be presented in this paper. |
