Cooling as well as heating circuits can be modeled as a network of elements that obey mass, momentum, and energy balance laws. Typical elements in such circuits are pipes, regulated pumps, regulated (multi-way) valves, and energy exchangers. Since cooling or heating can need a lot of energy, one is interested in understanding, reducing, and re-using energy flows. Supercomputing centers provide one important class of applications here. This article provides a detailed case study of a real system for which measurements and technical data are available. We briefly discuss our overall MYNTS framework for modeling, simulation, and optimization of such circuits. In more detail, we explain by means of a case study how we obtain and combine the network topology, element characteristics, and measurement data in order to set up and validate simulation models. Numerical results are presented and discussed. The case study is complemented in Clees et al. (Cooling Circuit Simulation I: Modeling. Springer, Berlin, 2017) (see pages 61--79 in this book) by a general introduction to the underlying physical model and its numerical treatment.
