Title: Coolant and ambient temperature control for chillerless liquid cooled data centers

Abstract

Cooling control methods include measuring a temperature of at least one component of each of multiple nodes and finding a maximum component temperature across all such nodes, comparing the maximum component temperature to a first and second component threshold and comparing the air temperature to a first and second air threshold, and controlling a proportion of coolant flow and a coolant flow rate to the air-to-liquid heat exchanger and the nodes based on the comparisons.
