Résumé

The aim of this work is to propose a black-box model to accurately predict the chilled water temperature dynamic response of a vapour compression chiller. The model is oriented to be of value in determining an adequate control algorithm based on compressor speed regulation. The model uses variables that are easily obtained in any commercial or industrial facility, such as the water inlet temperature and the compressor speed, to predict the chilled water outlet temperature. Several linear black-box model structures are proposed and their ability to describe the process behaviour is validated with experimental data from a monitored test bench. Finally, the Box–Jenkins structure shows the best fits, obtaining promising results. [Reprinted with permission from Elsevier. Copyright, 2010].
