저온측과 고온측 냉매간 열교환이 열펌프의 성능특성에 미치는 영향
Effect of the Heat Exchange between Low and High Temperature Refrigerant on the Heat Pump Performance
초록
The ambient air is commonly used as low-temperature heat source for heat pump operation. However, the coefficient of performance(COP) of the air to water heat pump is decreased with the ambient air temperature drop. In this study to solve this problem, the AVACTHE(Automatic Variable Area Capillary Type Heat Exchanger) with 3 levels of heat exchange area(0, 1,495.4, 1,794.5
