METHOD FOR ENHANCING COOLING EFFICIENCY OF A COMPUTER ROOM AIR CONDITIONING UNIT

摘要

A method for enhancing the cooling efficiency of a computer room air conditioning unit, in a data center, is provided. Raised floor panels are carried on a pedestal support system. The floor panels divide a data center, into upper and lower plenums. A cold aisle is includes air-grate floor panels. The computer room air conditioning unit is operated to condition a heated hot aisle return air flow. A server rack has a front, a back, and side rack support frame members. The support members define an interior server compartment. At least one damper door frame has a top, a bottom and side members. The door frame members define at least one open air flow panel portion. A series of horizontal damper blade members are pivotally mounted in the open panel portion. The damper blade members are pivoted to direct a stream of the conditioned air flow over heat generating components contained in the interior server compartment in order to elevate the temperature of the heated return airflow at the air conditioning unit.
