Simulation and experimental validation on steady-state distribution parameters of heat transfer performance for water-cooled heat exchangers

Develops a steady-state simulation model for the sheet and tube heat exchanger with distribution parameter method. To validate the heat exchanger model, measures the inlet and outlet water temperatures of both the evaporator and the condenser, as well as the heat exchange rate with the refrigerant of R124 through the simulation test. Compares the experimental results with the simulation data. Analyses the heat transfer performance based on the simulation data. The results show that the relative deviation of outlet water temperatures for the condenser and the evaporator is within ±2.5% and ±3% respectively. The simulated maximum deviation of heat exchange rate for evaporation and condensation is 1.72% and -5% respectively. When the cooling water inlet temperature rises by 1 ℃, the heat exchange rate decreases by 1.37%. The heat exchange rate will decrease by 5.17% if the outlet water temperature of evaporator rises by 1 ℃.
