Abstract
Groundwater heat pump (GWHP) systems can achieve the higher coefficient of performance (COP) and more energy-saving than the conventional air-source heat pump (ASHP) systems. The performance of GWHP system significantly depends on conditions of groundwater and thermal properties of underground. For the optimum design of a GWHP system, it is necessary to comprehensively consider them and building conditions. In this research, heating and cooling experiments with real-scale experimental equipments have been conducted to examine the performance of system. Furthermore, the feasibility study of GWHP system on two different conditions and three local sites has been performed by using heating and cooling load model in building. In the result, cost payback time of this system has been calculated and it has been found that this system is enough efficient in the site where heating and cooling load are balanced.
