%X Presently the emphasis is to utilize renewable energy sources such as solar energy, geothermal energy, ocean thermal energy, etc. and waste heat from industrial processes, to produce refrigeration. The aim of many researchers was to develop thermal refrigerator and heat pump systems using heat energy as energy input for achieving better performance, compactness and cost effectiveness. In the present study, a simple thermal jet refrigerator is constituted into a heat pipe system and a thermodynamic analysis is presented for the performance prediction and design of such system. The effects of generator, evaporator and condenser temperature on the Coefficient of Performance (COP) of the system and entertainment ratio of the ejector are studied. It is found that COP and ejector entrainment ratio are higher at high generator and evaporator temperatures whereas they are lower at high condenser temperatures.
