Abstract

Solar energy is freely and abundantly available onthe surface of the Earth, solar adsorption refrigeration devices are veryuseful to meet the needs for cooling requirements in refrigeration,air-conditioning, ice-making and food preservation in isolated areas. Theclimate of the India comprises wide range of the weather across a vastgeographic scale which can affect the coefficient performance of the solaradsorption refrigeration system. This paper primarily focuses on theperformance and experimental investigation of the solar adsorption system fortropical wet and dry climatic zone of India. The objective of work is tounderstand the different parameters which may affect on the performance thesolar adsorption refrigeration system and enhancement by taking properparameters for the improvement of COP .For that we have to consider certainfactors which are relevant to the intensity of solar radiation such as locallatitude, angle of inclination of the receiving surface, weather conditionsetc. The system proposed consists of a flat plate collector having sorptionbed, condenser and an evaporator. The working pair of fluid used is low gradecharcoal and methanol and comparative analysis is done for tropical region.
