Servers Rooms / Data Cooling Centers are used around the globe to keep the servers cool which keeps data for cell phone towers, the internet, and more. They need proper air-conditioning to keep them cool and operational. It is achieved by the use of CRAC units which use a fan coil system. The fan coil system is operated either using direct expansion refrigeration type or chilled water type. Direct expansion type is the type in which the refrigerant just circulates back and forth in pipes inside a fan coil CRAC unit. In the other type, chiller application, a large chiller is installed on a roof which could be an air-cooled or water-cooled chiller. Chillers as the name tell are used to cool the refrigerant which is further used to cool the water for the CRAC units inside the data centres. They can be small or massive according to the size of the building. Most of the time, a centrifugal chiller is used to pump the refrigerant but it can be a different type according to the brand. Chillers come in different capacities, sizes, and different types accordingly. We at DHVAC Heating, Refrigeration, Appliances & Air-conditioning Systems install, maintain and service them all.
