Modelling a PCT40 heat exchanger for control purposes

Abstract

This paper presents a simulation model of a PCT40 heat exchanger. It starts with a motivation, followed by description of the system and of the whole modelling process. The mathematical model includes simplified description of heating and cooling systems together with a more detailed description of a proportioning solenoid valve. It is formed using combination of both analytical and empirical approaches and the resultant simulation model is compared to real-time measurements in terms of both static and dynamic properties. The overall results indicate that although the model is relatively simple it can be used for control-oriented simulation experiments, which was the purpose of this work and saves time during experiments on this system. © ECMS Thorsten Claus, Frank Herrmann, Michael Manitz, Oliver Rose (Editors).
