摘要：
Ground-source heat pumps (GSHPs) are attractive alternatives to conventional heating and cooling systems owing to their higher energy utilization efficiency. GSHPs, also known as geothermal heat pumps, are a promising new technology that has been used for the last few years in the Korean market. A geothermal energy system has been developed over the last two years and a ground-heat-source water thermal-storage heat-pump cooling and heating system in Gu-mi city was built. Trial performance tests were conducted on the system. The actual proof examination was accomplished and the performance of the system was investigated. The coefficient of performance of the heat pump unit was 4.29 for cooling and 3.97 for heating. Thus, the presented system is expected to be used for energy savings and active alternative energy use.
