The effect of heat recovery on the performance of a glazed solar collector/regenerator

Abstract This paper describes an experimental study for the effect of a heat exchanger on the performance of a 2 m × 9 m glazed solar collector/regenerator for an open-cycle absorption solar cooling system operated under humid climates. The working fluid is aqueous lithium chloride solution and the refrigerant is water. Heat is recovered from the outlet solution to preheat the inlet solution by a heat exchanger. The results show a significant performance increase of 25%. Data are correlated by dimensionless parameters.
