Summary

A dynamic model of a Vapour Compression System (VCS) has been developed under the Modelica/Dymola platform aiming at three specific goals: numerical robustness, low resolution time, and accurate predictions. The aforementioned characteristics are crucial to predict the VCS behaviour when large refrigeration architectures are taken into consideration. The internal components of the developed VCS have been modelled based on simplified physical formulations and empirical information seeking for an appropriate compromise between physical representativeness and fast resolution. The VCS model has been comprehensively tested to evaluate its performance. It has proven to be suitable for the defined purpose as it is reliable from the numerical point of view, fast in terms of CPU time consumption, and with accurate predictions. This paper presents a complete evaluation of the developed VCS model.
