지열 히트펌프 시스템의 Exergy 변화를 통한 시스템 효율에 관한 연구

A Study of System Efficiency according to The Exergy Change of Geothermal Heat Pump System

This study is experimented with device that heat exchanger instead of condenser and evaporator changed dual tubes heat exchanger under heating condition and cooling condition The results with the experimental is that the ratio of Irreversible losses represents that the largest amount of loss is the compressor and the condenser, evaporator, expansion valve in the order. Also, COP of power according to effect of water is confirmed that performance of cooling and heating are improved when ΔTLS is lower the most efficient driving method is that heating is low and cooling is high With this study, It is found that to select a higher reduces power consumption and generate maximum calorie under cooling.
