A Study of Refrigerant Exercy and Geothermal Cold․Hot Water by The Geothermal Heat Pump System

This study is about the efficient operation method of heat pump by hot and cold water, Geothermal heat water and refrigerant exergy along to the change of ΔTLS when air conditioning and heating operation of geothermal heat pump system. Furthermore, according to the contemplation of coefficient of performance(COP) experiment result, efficient performance was showed at COPc(4.92) when ΔTLS was 22.1℃ under air heating and COPc(6.72) when ΔTLS was 0.3℃. Therefore as ΔTLS is lower, the temperature and pressure are constant and the performance of air conditioning and heating are improved. In counclusion, this analysis would contribute to the progress of Geothermal Heat Pump.
