ADSORPTION COOLING SYSTEM DRIVEN BY SOLAR COLLECTOR: A CASE STUDY FOR TOKYO SOLAR DATA

An analytical investigation has been performed to study the possibility of application of solar cooling for the climatic condition of Tokyo, Japan. Silica gel-water adsorption cooling system has been taken into consideration for the present study. Based on the solar radiation data it is seen that at least 15 collector (each of 2.42 m(2)) is required to achieve the required heat source temperature (around 85 degrees C) to run the cooling unit. It is seen that the unit provides the cooling capacity around 10 kW at noon with base run condition, while the system provides the solar COP around 0.3, however, the solar collector size may be reduced by optimizing the cycle time.
