Abstract—In this paper solar driven triple effect refrigeration cycle is investigated from the viewpoint of both energy and exergy concepts of thermodynamics. In this cycle ejector organic Rankine cycle, absorption refrigeration cycle and transcritical CO2 refrigeration cycles are integrated in order to obtain a range of temperature for varied simultaneous use. Parabolic trough collectors are used to utilize solar thermal energy for driving the refrigeration cycles. Exergy analysis determines the destruction and losses of exergy in various components and hence in overall system. Exergy efficiencies provide measure of approach to ideality while exergy destruction and losses provide measure of the deviation from ideality. Energy efficiency is found to be around 16.42% while exergy efficiency is 1.64%. The maximum thermodynamic irreversibility occurs in parabolic trough collector, followed by generator of absorption refrigeration system, heat recover vapour generator and ejector.
