Abstract:
1. A method of cooling a data center during operation of electronic equipment, comprising: monitoring a temperature outside of the data center; when the temperature outside of the data center is below a predetermined value, maintaining a temperature within the data center below an inside setpoint by flowing water through a cooling system within the data center, wherein the water is at least as cool as a predetermined water supply temperature; determining when the temperature outside of the data center rises above the predetermined value; and when the temperature outside of the data center rises above the predetermined value, allowing the temperature within the data center to be greater than the inside setpoint by flowing water through the cooling system that is warmer than the predetermined water supply temperature, wherein the temperature within the data center is below the inside setpoint for at least 90% of an operating time of the electronic equipment.
