Power saving in solar absorption cooling systems

Solar absorption cooling systems are viewed as potential future cooling systems that would reduce the current dependence of cooling systems on conventional energy sources. Of particular interest in solar absorption cooling systems is the amount of power consumed per unit of 'end use' refrigeration as compared to that consumed by conventional vapour compression systems. The sources of power consumption in both vapour compression and solardependent absorption cooling systems are discussed and their contribution to the total power consumption per refrigeration unit is determined. The effects of the cooling and chilled water temperatures on the performance and power consumption of both systems are discussed. It is shown that, under certain conditions, the power consumption per refrigeration unit in both systems is equal. Two descriptive diagrams of power consumption in both systems are presented and could be used to determine the feasibility of using either.
