Abstract

In this paper has presented a simple method to determine a discrete time model with take the case is heat exchanger model HE158C. The all discrete time model resulted is a first order system. The model can be designed with four different types of heat exchangers and two stainless steel sumo tanks for hot and cold water sources. The four heat exchangers consist of shell exchangers. This paper covers a discrete time model of the four heat exchanger types. The modelling process includes the following steps, i.e. experiment designs, selection of model validation. The experiment designs are to study the reliability and accuracy of the existing equipment available and to collect the real data set input-output and data pre-processing. The state space model is selected as a model structure. The Gauss method is chosen as criterion for fitting and validating models. The parameters of interest are estimated using the least squares method. The results are calculated using MATLAB program.
