An Experimental Study on the Performance of a Sea Water Heat Source Cascade Heat Pump
해수열원 캐스케이드 열펌프시스템의 운전 특성에 관한 실험적 연구
Abstract
The purpose of this study is to investigate the performance of a sea water heat source cascade heat pump system. R717(Ammonia) is used for a low-stage working fluid while R134a is for a high-stage. In order to gain a high temperature supply water in winter season, the system is designed to perform a cascade cycle. In this study, two experiments were carried out. One is a system starting test from the low load temperature of
