Abstract
In the most of industrial process the waste heat energy increases the production cost. Using this waste heat to produce power or cooling can decrease the costs and increases the thermal efficiency of the systems. A growing need for refrigeration in industry and for building cooling is well known due to the main cause of growing the demands of higher living standards , by the increasing requirements for comfort, by increasing thermal load of buildings. Using LiBr-H2O solution in the vapour absorption refrigeration systems offers very good thermodynamic efficiency for cooling at over 0 0C temperature than the other solutions. In this paper, we analyzed solar assisted half effect vapour absorption refrigeration system cascaded by vapour compression refrigeration system using ecofriendly refrigerants and developed thermodynamic model to predict the variation of generator , absorber , condenser temperatures on first and second law efficiencies and to predict the solar collector area required.
