Performance Simulation of Two-Bed Silica Gel-Water Adsorption Chillers Performance Simulation of Two-Bed Silica Gel- Water Adsorption Chillers

This paper presents a transient model of a two bed silica gel-water solar adsorption cooling system. This program is then utilized to simulate the performance of a sample solar adsorption cooling system used for cooling a room that comprises an area of 9 m2 located in Nancy city in France. The system has been simulated with typical weather data of solar radiation and ambient temperatures of France. The results include effects of the hot water temperature, cooling water temperature and chiller water temperature and cycle time on COP, refrigeration capacity and cycled mass are studied in order to determine their optimum values able to maximize the overall performance of the system under analysis for its adaptation to the Tunisian climate.
