Abstract: A data center thermal control system includes a local cooler configured to cool a local coolant used for cooling electronic hardware, an outer heat exchanger configured to exchange heat from fluid to outside air, and a fluid circulation system configured to convey heat from the local cooler to the outer heat exchanger by circulating at least one fluid cooling medium, the fluid circulation system including a cold portion directed to the air cooler. The thermal control system also includes one or more processors and a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, would cause the one or more processors to govern the outer heat exchanger to cool fluid in the cold portion to a first target temperature during a hot season, and cool fluid in the cold portion to a lower target temperature during a cold season.

Abstract: A data center cooling system has an indoor portion wherein heat is absorbed from components in the data center, and an outdoor heat exchanger portion wherein outside air is used to cool a first heat transfer fluid (e.g., water) present in at least the outdoor heat exchanger portion of the cooling system during a first mode. When an appropriate time has been reached to switch from the first mode to a second mode, the outdoor heat exchanger portion of the data cooling system is switched to a second heat transfer fluid, which is a relatively low performance heat transfer fluid (compared to the first fluid). It has a second heat transfer fluid freezing point, lower than the first heat transfer fluid freezing point, and sufficiently low to operate without freezing when the outdoor air temperature drops below a first predetermined relationship with the first heat transfer fluid freezing point.
