Abstract

This study deals with thermodynamic analysis of solar assisted absorption refrigeration system. A computational routine based on entropy generation was written in MATLAB to investigate the irreversible losses of individual component and the total entropy generation (????? ????????????) of the system. The trend in coefficient of performance COP and ????? ???????????? with the variation of generator, evaporator, condenser and absorber temperatures and heat exchanger effectivenesses have been presented. The results show that, both COP and S? tot proportional with the generator and evaporator temperatures. The COP and irreversibility are inversely proportional to the condenser and absorber temperatures. Further, the solar collector is the largest fraction of total destruction losses of the system followed by the generator and absorber. The maximum destruction losses of solar collector reach up to 70% and within the range 6-14% in case of generator and absorber. Therefore, these components require more improvements as per the design aspects.
