Abstract (en)
[origin: WO0216854A1] A computer room reduced air flow method and apparatus is provided which utilizes an increased delta T to reduce the required air quantity required from an air conditioning system (14), thus resulting in a reduced air flow capability. Specifically, the present invention utilizes an approximately 40 degree delta T to reduce the CFM requirements by substantially 50% so as to correspondingly reduce the required power for the fan (125) by approximately 50% so as to result in substantial energy savings. The present invention serves to communicate cooling air from a cooling apparatus into an air passageway (104c), guiding the cooling air within the air passageway into the equipment assembly and introducing the air released from the equipment into either a plenum for communicating such released air to the cooling apparatus or introducing the air released from the equipment into the room in which the equipment and/or cooling apparatus are located.
