Solar energy is the only source which is abundantly available and which can beused to power a cooling system that is based on absorption cycle.Solar cooling system can be used to provide refrigeration for food and medicinesand comfort cooling also. Such systems are specifically applicable to the large applications having large cooling loads for particularly big periods of a year. Peak demandfor the cooling of a building and the highest availability of solar radiation are in similar phase, which makes solar cooling of any building a potential energy source andalso a green solution.In this project, The Lithium bromide-water absorption cycle is used becauseof its lower operating temperature. By considering it as a working fluid a solarabsorption refrigeration is designed to cool the datacenter with respect to the weathercondition of Texas state. The system is designed in such way that the usage ofelectricity can be totally eliminated in the sunny days and partially eliminated in thewinter, when the solar energy is not available at its full intensity.Regular vapor-compression cooling systems are expensive as they are poweredby electricity and are dependent on fossil fuels. Dropping the use of such systems willalso help in reducing their effect on Ozone layer depletion and Global warming.Now-a-days, absorption chillers deliver almost 50% of the worldwide commercialcooling load. This green solution of solar powered air conditioning system togetherwith thermal storage will help in reducing total electricity consumed and increasingthe overall cooling capacity of the system.
