摘要：
The emperical correlations for initial conditions needed to predict frost formation based on the structural model were presented and they enabled to predict the frost growth without any experimental data under various frosting conditions. The difference in characteristics between parallel and counter flow type heat exchangers with frosting has been studied experimentally and theoretically. It was found that with growing of frost layer, the average thermal resistance on counter flow type because larger in comparison of that on parallel flow type and the temperature efficiency for counter flow type gradually approached that for parallel flow type.
