Model Analysis on the Performance of Fin-tube Heat Exchanger with Variable Condition/Structure

Abstract

The performance of fin-tube heat exchanger is variable with not only condition parameters,but also structure parameters.So a performance analysis model was established to comprehensively analyze and to predict the performance of fin-tube heat exchanger with variable condition and variable structure.The calculated results of the model were verified by the experimental data: the mean relative deviations are lower than 6% under dry conditions or 20% under wet conditions,which show a good agreement both in nume...
