Patent ID: 8051672

Claim:
An electronic equipment cabinet comprising: an enclosure defining an interior space and having an upper portion and a lower portion; a support being disposed with the interior space and being configured to receive electronic equipment, the lower portion defining a base plenum configured for disposal of at least one heat exchanger, the at least one heat exchanger being in fluid communication with a low temperature fluid supply and a high temperature fluid return, and configured to reduce a high temperature gas to a low temperature gas; a closed loop gas flow distribution pathway including a first plenum communicating with the base plenum and being configured to direct the low temperature gas to the support, the gas flow distribution pathway further including a second plenum configured to receive a high temperature gas flow from the support and direct the high temperature gas flow to the base plenum; a temperature sensor being disposed with the enclosure to sense the temperature of the high temperature gas flow within the enclosure; a pressure sensor being disposed with the enclosure to sense the pressure of the at least one fan; and a control module configured to receive temperature sensing data from the temperature sensor and pressure sensing data from the pressure sensor to control the at least one fan and the at least one heat exchanger for regulating temperature of the high temperature gas flow.
