ARCHITECTURE TO PROVIDE LIQUID AND CLOSED LOOP AIR COOLING

A method for cooling one or more Information Technology (IT) units, the method comprising adjusting a first valve controlling liquid flow in a primary loop, wherein the primary loop comprises: at least one dry cooler of a dry cooling section, and an air/liquid exchange section comprising at least one air/liquid exchange device that provides air cooling to the one or more IT units. The method further comprising adjusting a second valve controlling liquid flow into a liquid loop interface, the liquid loop interface being connected to a secondary loop, the secondary loop comprising the one or more IT units; and at least one liquid heat exchange device of the liquid loop interface that provides liquid cooling to the one or more IT units, and wherein adjusting the first and second valves controls the ratio of liquid cooling to air cooling to the one or more IT units.
