AbstractIn this paper dynamics of plate heat exchanger networks is given by combining dynamic models of plate heat exchangers in the network. A mathematical model for plate heat exchanger is developed based on energy balance. Dynamic simulation of plate heat exchanger networks to different step changes in flow rate of both process fluid and utility fluid is conducted using MATLAB simulink. Plate heat exchanger networks has been controlled using split range control method with two manipulated variables which are process fluid and utility fluid. The simulation results showed that split range controller is the best action and gives better response compared with conventional controller.
