Ejection cooling system is analyzed by the second law of thermodynamics in this study. It is mainly consisted of a boiler, an ejector, an expansion device, a condenser, and an evaporator. Special focus is stressed on the variation of exergy in each component. The working refrigerant received exergy from boiler and pump and cons umed in other parts of the system. The coefficients of performance based on both the first and the second laws are computed respectively and thus the changes of energy and exergy in each component of the system can be readily understood. In addition, the boiler temperature, evaporator temperature, condenser temperature, nozzle efficiency, and diffuser efficiency are varied parametrically and the results are tabulated. Filly, a compression cooling system operating at the same con made to compare with the present results.
