The new evaluation method of energy consumption for EHD enhanced heat transfer is applied to analyze the experimental data of condensation heat transfer of R134a in the enhanced horizontal tube and R123 in the enhanced vertical tube.The results show that the profit factor of available energy decreases with the increase of the voltage for R134a,while increases with the increase of the voltage for R123 under the same heat flux given in experiments.The high value of the enhancement factor does not certainly accompany with the high value of the profit factor of available energy.
