Patent ID: 8223495

Claim:
A system for providing cooled air to electronic devices, comprising: a cooling tower; a water treatment system fluidly coupled to the cooling tower; an air-to-liquid heat exchanger connected by a pair of pipes to the cooling tower and positioned to receive heated air from a group of electronic devices; and a controller arranged to: determine a temperature of a cooling fluid stored in a first storage tank in fluid communication with the cooling tower; based on the temperature being within a predetermined range of cooling fluid temperatures, adjust one or more valves of a plurality of valves to circulate the cooling fluid from the first storage tank to a liquid-to-liquid heat exchanger in fluid communication with the air-to-liquid heat exchanger; and based on the temperature being less than the predetermined range of cooling fluid temperatures, adjust one or more valves of the plurality of valves to mix the cooling fluid from the first storage tank with a fluid exiting the liquid-to-liquid heat exchanger and circulate the mixed cooling fluid to the liquid-to-liquid heat exchanger.
