Performance Analysis of Water-to-Air Heat Pump System under Water Temperature and Load Ratio
열원 및 부하조건에 따른 물-공기 히트펌프 시스템의 성능분석
Abstract
Heating and cooling performance has been analyzed for the water-source heat pump system using raw water from Daechung reservoir. During heating operation from March to May, water temperature is not good condition for a heat source due to the higher atmospheric temperature. Avearged heating load ratio is only 14.3%, and the averaged unit COP and system COP are estimated to be 2.46 and 2.15 respectively. The COP is affected considerably by the water temperature, and the unit COP is increased from 2.16 at
