The operation principle of data center of the present utility model supply air system: the cold air that described precise machine room air conditioner 3 blows out enters described plenum chamber 4 from its air outlet, enter described ajutage 5 by the air inlet of described ajutage 5 after air-flow is stable in described plenum chamber 4, enter described cold passage 1 by the air outlet of described ajutage 5, described air-supply orifice plate 7 afterwards.The cold air entering ajutage 5 can be divided into upper and lower two strands of air-flows by described deflector 6, and it is anterior that lower stream of airflow mainly leads to cold passage 1, and namely apart from the rack 2 that air-conditioning is nearer, upper air mainly leads to cold passage 1 rear portion, rack 2 namely far away apart from air-conditioning.Fig. 4, Fig. 5 show impact on air current composition in ajutage 5 and cold passage 1 after the change of deflector 6 angle.Preferably, the rotating shaft on described deflector 6 is driven by motor and drives described deflector 6 do clockwise or rotate counterclockwise.Can allocate the air output at air-supply orifice plate 7 two ends by regulating the anglec of rotation of deflector 6; Preferably, be provided with temperature sensor in each server in described rack 2, the leaving air temp of each server can be obtained.When near-space in cold passage 1 adjusts rack 2 temperature of end to rise, as in Fig. 5, can rotate clockwise deflector 6, now on the downside of deflector 6, intake increases, and in cold passage 1, near-space tune terminal cabinet 2 dispels the heat and strengthens; When rising away from rack 2 temperature of air-conditioning end in cold passage 1, as in Fig. 5, can rotate counterclockwise deflector 6, now on the upside of deflector 6, intake increases, and strengthens in cold passage 1 away from the heat radiation of air-conditioning terminal cabinet 2.As can be seen here, deflector 6 is deflected different angles and can adjust upper and lower sides intake ratio, thus the specific heat load of diverse location rack 2 in cold passage 1 is changed, by the region of cold air from the region guiding refrigeration deficiency of excessively freezing.After adopting the utility model, the air outlet above described precise machine room air conditioner is directly connected with described plenum chamber, Such a design reduces machine room floor space.Ajutage 5 above its air-supply orifice plate 7 adds deflector 6 design can be improved because underground air-supply is not freely sent, and wind air current composition is unreasonable, even occurs the problem of wind short circuit.
In sum, data center of the present utility model supply air system, the cold air of described precise machine room air conditioner blowout enters plenum chamber from its air outlet, enters the air inlet of ajutage, enter cold passage by air-supply orifice plate after air-flow is stable in plenum chamber.Deflector is provided with in described ajutage, the cold air entering ajutage can be divided into upper and lower two strands of air-flows by described deflector, and lower stream of airflow mainly leads to cold channel front portion, namely apart from the rack that air-conditioning is nearer, upper air mainly leads to cold channel rear portion, rack namely far away apart from air-conditioning.Deflector can change angle according to the real-time device temperature in each several part rack, thus repartitions the air output of cold passage front and rear portions, coordinates the radiating requirements of each rack.The air having cooled rack is discharged from rack rear end face, again enters precise machine room air conditioner by return air inlet.This system can effectively avoid air to mix, and takes into account the cooling effectiveness of all racks in cold passage, reduces energy consumption for cooling, improves the radiating efficiency of rack in cold passage.And solve because underground air-supply is not freely given in prior art, wind air current composition is unreasonable, even occurs the problem of wind short circuit.So the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
