Abstract

For the plate heat exchanger of heat pump system, the convection heat transfer correlation of condenser and evaporator was used to simulate the heat transfer of heat exchanger, and the experimental test of heat exchanger was carried out in the heat pump system. The numerical simulation results were compared with the experimental results. The results show that the average error between the numerical simulation results of condenser and evaporator and the experimental results are 5.75% and 1.13% respectively, which proves that the simplified hypothesis, the heat transfer model and the solution method used in the numerical simulation are reasonable for the evaporation and condensation process of plate heat exchanger for heat pump.
