Abstract
The two-phase simulation models for a plate heat exchanger with R410A are established
and the error analysis and the comparison for the models are performed using the experimental data.Moreover
the factors to influence the performance of the heat exchanger are discussed.The average error of the modified model of condensation heat transfer is less than 5%.The accuracy of the modified model of evaporation heat transfer based on Yan and Lin increases by 10% compared with those in literature and its average err...
