IDENTIFICATION OF MATHEMATICAL MODEL OF WATER LINE IN HEAT EXCHANGERS

Heat exchangers are widely used in industries for the use of thermal energy generated from different processes. For a definite use of this energy, the temperatures of the hot and cold fluids passing through the heat exchanger must be monitored and controlled efficiently. A suitable model of the heat exchanger is required for monitoring and control purposes. The objective of this work is to mathematically model a heat exchanger using a system identification method using a computational tool. The methodology used consists of data collection and simulation of models, as well as the analysis of comparison of the estimated models with the real system. The results show that the identification through computational simulation presented satisfactory results.
