The mathematical modeling of plate heat exchanger was studied by introducing rectangular pulse change in inlet cold water flow rate and measuring the temperature of outlet cold water. A theoretical model for the plate heat exchanger was developed based on the heat balance and used the frequency response analysis techniques to determine the best model parameters. The results show that the dynamic behavior of plate heat exchanger can be approximated by a time delay with first order system and a closed fit between the theoretical coefficients of the system and these data by using frequency response method.
