Abstract


Adsorption solar cooling appears to have prospect in the tropical countries. The present study is a theoretical investigation of the coefficient of performance of a solar chiller adsorption in the site of CERER. The values of absorber plate temperatures obtained from numerical solutions of heat balance equations are used to predict the solar coefficient of performance of the solar refrigerator. The simulation technique takes into account the variations of ambient temperature and solar radiation along the day. The effects of optical parameters of the glass cover such as absorption and transmission coefficients on the coefficient of performance are analyzed.  As a result, it is found that the higher values of COP are obtained between 11 hours and 13 hours during the morning when the temperatures of the absorber plate and the ambient temperatures increase. Moreover the COP increases with the coefficient of transmission of the glass cover but the main parameter acting on the variations of the COP remains the temperature of the evaporator.
