The Analysis on the Effect of Cold and Heat Fluid Inlet Temperatures on the Thermodynamic Performance of Heat Exchanger

Based on the exergy analysis method,the thermodynamic performance of high and low temperature heat exchangers is analysed and the calculating expressions of exergy efficiency are given,which can be used to study systematically the effect of cold and heat fluid inlet temperatures on the exergy efficiency of the high and low temperature heat exchangers on the condition of considering pressure exergy loss and not.
