Abstract
A method and apparatus for supplying cooling air to electronic equipment from ones of at least two sources. A detector detects whether the quality, such as the temperature of the cooling air from a source, is satisfactory and if not shuts the damper to that source and opens the damper to another source. A main controller provides additional control signals for controlling the dampers to protect the electronic equipment, or for shutting down the electronic equipment.
Claims16
Apparatus for cooling electronic equipment, comprising
- at least two sources of cool air;
- a damper in series with each of said sources;
- sensors to detect unsatisfactory cooling air being received from each of the sources;
- each damper controlled by a switch;
- and
- a processor responsive to signals from said sensors for controlling the operation of said dampers in such a way as to provide satisfactory cooling air to said electronic equipment.
