해수 히트펌프시스템을 이용한 냉동법 담수화시스템 성능해석

Abstract

In this study, a freeze desalination cycle with seawater heat pump system is simulated and designed for the basic data for the design of freeze desalination system. The basic model of seawater heat pump system is refrigeration cycle and indirect freeze desalination method is used for seawater desalination. The cycle performance of seawater heat pump such as COP, compressor work, condensing capacity was analyzed and the desalination performance such as fresh water productivity and energy per unit fresh water productivity were compared with respect to the seawater temperature of condenser inlet and ice ratio in the evaporator. The compressor work and condensing capacity decreased with respect to the increase of seawater inlet temperature. The energy per unit fresh water productivity in case of 8℃ seawater inlet temperature showed 28.9% lower than that of 20℃.
