Data Center HVAC cooling systems. In this video, we look at data center HVAC designs with a focus on the cooling systems and air management strategies used, as well as design analysis with Computational Fluid Dynamics (CFD) on SimScale (https://www.simscale.com/). We cover raised floor, hot and cold aisle, hot aisle containment, cold aisle containment, CFD simulations, CRAC units, heat exchangers, chillers, free cooling, water and air cooled chillers as well as cooling towers.
