Abstract
A system for controlling the temperature of a rack includes a connecting plenum configured to receive incoming cooling air from outside a rack for cooling the rack; a front plenum connected to the connecting plenum and configured to receive cooling air from the connecting plenum and deliver the cooling air to the rack, the cooling air being warmed by powered electrical components as it passes through the rack; at least one ventilator for recycling warmed cooling air from the rack back to the connecting plenum to be mixed with incoming cooling air; a sensor for sensing temperature of air in the rack; and a controller for controlling the at least one ventilator based at least on the sensed temperature.
Claims20
A system for controlling the temperature of a rack, comprising:
- a connecting plenum configured to receive incoming cooling air from outside the rack for cooling the rack;
- a front plenum coupled to the connecting plenum and configured to receive the incoming cooling air from the connecting plenum and deliver the incoming cooling air to the rack, the incoming cooling air being warmed by powered electrical components disposed in the rack as it passes through the rack;
- and
- a ventilator for recycling the warmed cooling air from a rack back side to the connecting plenum to be mixed with the incoming cooling air.
A system, comprising:
- a rack;
- a plurality of information handling systems disposed in the rack;
- and
- a temperature control system for controlling the temperature of the rack, comprising:
- a connecting plenum configured to receive incoming cooling air from outside the rack for cooling the rack;
- a front plenum coupled to the connecting plenum and configured to receive the incoming cooling air from the connecting plenum and deliver the incoming cooling air to the rack, the incoming cooling air being warmed by the information handling systems as it passes through the rack;
- and
- a ventilator for recycling the warmed cooling air from a rack back side to the connecting plenum to be mixed with the incoming cooling air.
A method for controlling a cooling system configured to control the temperature of an information handling system rack, the method comprising:
- setting a target temperature or a target temperature band for an information handling system rack;
- operating a cooling system such that the incoming cooling air is received from outside the cooling system into a connection plenum, flows from the connection plenum to a delivery plenum, and flows from the delivery plenum through the information handling system rack, the cooling air being warmed by electrical components disposed in the information handling system rack as the incoming cooling air flows through the information handling system rack;
- and
- configuring a ventilator to control an amount of the warmed cooling air from the information handling system rack to recycle back into the connection plenum to mix with the incoming cooling air.
