Description

FIELD At least one embodiment pertains to cooling systems, including systems and methods for operating those cooling systems. In at least one embodiment, such a cooling system can be utilized in a datacenter containing one or more racks or computing servers. BACKGROUND Datacenter cooling systems use fans to circulate air through server components. Certain supercomputers or other high capacity computers may use water or other cooling systems instead of air-cooling systems to draw heat away from the server components or racks of the datacenter to an area external to the datacenter. The cooling systems may include a chiller within the datacenter area, which may include area external to the datacenter itself. Further, the area external to the datacenter may include a cooling tower or other external heat exchanger that receives heated coolant from the datacenter and that disperses the heat by forced air or other means to the environment (or an external cooling medium). The cooled coolant is recirculated back into the datacenter. The chiller and the cooling tower together form a chilling facility.
