INTEGRATING A DATA CENTER THERMAL CONTROL SYSTEM AND INDIVIDUAL FAN CONTROLLERS FOR CONTROLLING A THERMAL ENVIRONMENT IN A DATA CENTER ROOM
First Claim
1. A method for managing a thermal environment in a data center room, comprising:
- receiving, by a thermal control system for a data center room for controlling an ambient temperature in the data center room to meet an ambient temperature set point, a plurality of ambient temperature votes from a plurality of fan controllers positioned in the data center room each for controlling fan speeds for at least one separate fan from among plurality of fans each positioned within a separate system from among a plurality of systems within the data center room; and
setting, by the thermal control system, the ambient temperature set point to a lowest ambient temperature specified in the plurality of ambient temperature votes.

Abstract
A thermal control system for a data center room, for controlling an ambient temperature in the data center room to meet an ambient temperature set point, receives multiple ambient temperature votes from multiple fan controllers positioned in the data center room each for controlling fan speeds for at least one separate fan from among multiple fans each positioned within a separate system from among multiple systems within the data center room. The thermal control system sets the ambient temperature set point to a lowest ambient temperature specified in the multiple ambient temperature votes, such that the thermal control system and fan controllers operate as independent systems, but are integrated for selecting an ambient temperature that minimizes the power required for controlling a thermal environment in the data center room.
