태양열을 이용한 흡수식 냉방시스템의 시뮬레이션과 운전조건의 검토

Abstract

Solar/absorption cooling system was analyzed and its operating condition was examined. For the system, the optimum size of absorption refrigerator and collector area should be determined. As the temperature of water supplied to the generator increases, the collector efficiency decreases whereas the cofficient of performance of absorption refrigerator increases up to a certain point, and vice versa for decreasing of the temperature of water supplied to the generator. Thus if the cooling load is given, the appropriate operating condition can be determined between the two opposing trends by simulation program.

As an example of the simulation, the case of Jejudo province was studied. Under the conditions(such as weather data and prices of components, etc.) given in the sample calculation, the result shows that the optimum temperature of water supplied to the generator turned out to be 80.3℃, and still shows a large economical disadvantage in present stage compared to the case of conventional vapor compression cooling heating combined heat pump system.
