【Abstract】 With a view of making the application of exergy in refrigeration more noticeable in our country, the paper introduces the thermodynamic foundamentals of exergy concepts and the equations of exergy balance and exergy loss for various apparatus in refrigerating systems. The use of exergy for the analysis of vapor-compression type refrigerator is also demonstrated. Exergy-enthalpy diagram and exergy flow diagram are plotted. Finally, the advantages of exergy diagrams and exergy analysis are shown and the exergy efficiency of some domestic refrigerators is tabulated.更多还原
