Performance Analysis of Hybrid Heat Pump System of the Air-to-Air/Air-to-Water with the Ambient Temperature
외기온 변화에 따른 공기-공기/공기-물 형태로 된 복합형 열펌프 시스템의 성능 특성 분석
Abstract
The hybrid heat pump system of the air to air and / or air to water was composed and its COP was analyzed with the ambient temperature on the opened and closed loop system respectively. The results be indicated by the equation(7) that the COP(Coefficient of Performance) of air-source(air to air and / or air-water) heat pump is effected with the ambient air temperature and AVACTHE.(Automatic Variable Area Capillary Type Heat Exchanger) 2. The COP of air-to-water heat pump without AVACTHE decreased in accordance with the ambient temperature decrease, however in case of the heat pump with AVACTHE the COP was maintained at 2.8∼3.0 level when the ambient temperature decrease from -
