This tutorial models room air-conditioning and a server cooling system.
Reference Case
In the reference case, cooling is achieved using a single compression chiller (see following figure).
Two Compression Refrigeration Systems
In the first variant, the cooling demands are met separately by two chillers (see following figure).
Two Compression Refrigeration Systems and Free Cooling
Furthermore, in the second variant, it is possible to cool directly via a cooling tower, provided the ambient temperature is below 5 °C (see following two figures).
