When thermal energy flows between fluids, from a solid surface to a fluid, or between particles, and the flow of that thermal energy occurs at different temperatures, that combination of fluid and thermal energy is known as a heat exchanger. Industrial heating and cooling heat exchangers are commonly employed. Applications in the transportation, building, chemical, and refrigeration industries. For the heat exchanger process the suitable control scheme is provided by implementing the cascade control with optimized PID controller with various optimization techniques such as ZN method, Process Reaction Curve method and Fmincon-GA optimization techniques. The optimization is included to minimize the maximum peak overshoot to less than 5 %, the settling time 10% and nullifying the offset.
