배가스 열회수 히트펌프 시스템 실증을 통한 운전특성 분석

Abstract

The performance test of the 15 RT grade heat pump system with flue gas heat recovery was performed in the Korea Institute of Energy Research. The flue gas is exhausted from the 320 RT absorbtion chiller-heater in winter season. Using this flue gas, source water is heated by condensed type heat exchanger in by-pass. And the operating characteristics of the heat recovery heat pump system were analyzed. Based on the results of the experiments, operating maps were obtained and optimum operating range was suggested where the return and heat source water temperature are 51℃ and 31℃, respectively.
