This paper mainly deals with energy exergy analysis for finding irreversibilities in the brine cooled evaporator couped vapour compression refrigeration system using R134a ecofriendly refrigeration for reducing ozone depletion and global warming. The numerical computation was carried out using EES software on utilization of three nano particles (i.e. CuO, Al2O3 and TiO2) and it was observed that thre is a improvement in the refrigerating effect, first law efficiency and second law efficiency and reduction in the the system exergety destruction ratio.
