Claim of US Patent No. 10,398,065

1. A system for cooling a data center, the system comprising:a cooling system comprising:
a closed circuit of piping through which a coolant flows;
a coolant chilling unit, disposed as a load on the closed circuit of piping, that brings a temperature of the coolant to between 18 and 22 degrees Celsius;
an air cooling unit, disposed as a load on the closed circuit of piping, wherein the coolant flows directly from the coolant chilling unit to the air cooling unit via a continuous conduit of piping of the circuit of piping such that a path of coolant flow from the coolant chilling unit to the air cooling unit is uninterrupted by any flow control mechanism, the air cooling unit comprising:
a heat transfer surface that brings the flowing coolant into thermal contact with air in the data center, and
an air mover that cycles the air in the data center to the air cooling unit; and
a flow control mechanism, disposed on the closed circuit of piping, that controls the flow of coolant throughout the closed circuit of piping; and
a building management system comprising:
a memory medium comprising program instructions;
a bus coupled to the memory medium; and
a processor, for executing the program instructions, that when executing the program instructions causes the building management system to cause the cooling system to chill the coolant to a temperature between 18 and 22 degrees Celsius using the coolant chilling unit.
