Solar/absorption cooling system was analyzed and its operating condition were examined. For the system, the optimum size of absorption refrigerator and collector area should be determined. As the water temperature supplied to the generator increases, the collector efficiency decreases whereas the coefficient of performance of absorption refrigerator increases up to a certain point, and vice versa for decreasing of the water temperature 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 component prices, etc.) given in the sample calculation, the result shows that the optimum water temperature supplied to the generator turned out to be 78.8℃, and still shows a large economical disadvantage in present stage compared to the case of conventional vapor compression cooling system.
