Description

Improve the air flow controller of machine room refrigerating efficiency and safety

Technical field

The utility model relates to a kind of air flow controller that can improve machine room refrigerating efficiency and safety.

Background technology

Along with the development of information technology, current data center (machine room) scale is in continuous development, and the equipment that has thousands of is very general, its extensive, highdensity deployed with devices, and its energy consumption drops into huge.According to statistics; External advanced machine room PUE value (relatively more current in the world at present data center's electricity usage efficient measurement index) can reach 1.7; Our national PUE average is then more than 2.5; This shows that there is very big gap in China data center (machine room) with external aspect operational energy efficiency, the effective utilization rate of energy of data center's (machine room) also is one of greatest problem of facing at present of data center.

Therefore; Conspicuous contradictions such as " energy consumption is big, efficiency is low, cost high " that data center faces aspect managing power consumption; The policy and the call of national current promotion " eliminating the backward production facilities, realize energy-saving and emission-reduction " had not both been met; Simultaneously also be faced with huge cost competitive pressure, make the planning construction persons of data center have to examine closely again, make a strategic decision again, change the energy consumption tactical management aspect at data center.

The air return method (see figure 3) is gone up in air-supply under being that the conventional data centers machine room adopts; The computer room structure of this routine and air blow and return mode; Air conditioner in machine room wind causes cold to run off in a large number owing to fully mix with natural wind, causes the refrigerating efficiency of the air-conditioning equipment of machine room to reduce greatly; And do not cause power consumption significantly to increase owing to cold wind and equipment heating exchange fully, thereby cause overall energy consumption significantly to increase.Because the existence of above problem, thereby the PUE that causes existing machine room can not obtain effective optimization under existing ambient conditions.

At number of patent application is in the known open source literature of CN200920212264.8, discloses a kind of the air distribution control device of refrigerating efficiency " strengthen computer room ", though this air distribution control device will blow through cold channel seal system and the return air path thoroughly separates; Guaranteed correct circulation of air; Guaranteed that all cold airs are used for the refrigeration needs of equipment, but simultaneously also because the design of closed has caused the fire-fighting air in the machine room to have no idea to get in the cold passage; Only can when opening machine room door, get into cold passage; If do not open machine room door for a long time, the fire-fighting air can be accumulated in the machine room, has hidden fire-fighting danger.

The utility model content

The purpose of the utility model is to overcome the weak point in the background technology, and a kind of air flow controller that can improve machine room refrigerating efficiency and safety is provided.

For addressing the above problem, the utility model is realized through following technical scheme:

A kind of air flow controller that improves machine room refrigerating efficiency and safety of the utility model; It comprises by rack arrange face-to-face the cold passage that constitutes, be positioned at cold passage below can be through the floor openings of air-conditioning cold air, the door that is positioned at the ceiling at top and is positioned at cold passage two ends; The wherein said ceiling that is positioned at the top is provided with skylight and monitoring unit; According to the testing result of monitoring unit, through the unlatching in intelligent control appliance control skylight.

Described ceiling can adopt accordion structure.

Described monitoring unit comprises temperature, humidity, cigarette sense monitoring probe and force switch CCU.

Described skylight is prepared from through overlay film tempered glass.

Described air flow controller can adopt the cell modular design.

The raising machine room refrigerating efficiency of the utility model and the air flow controller of safety; Owing to adopted the design of closed, improve the utilization rate of cold comprehensively, help reducing the loss of the energy; The cooling of acceleration equipment efficiently radiates heat finally reduces the operation cost of data center; Ceiling is provided with the skylight of opening automatically according to the user preset value simultaneously, the fire-fighting gas in the machine room is got in the cold passage automatically, to guarantee the security against fire of machine room; Be prepared from through overlay film tempered glass, realize 99% light transmittance.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explain.

A kind of air flow controller that improves machine room refrigerating efficiency and safety of the utility model; It comprises by rack 1 arrange the cold passage 2 that constitutes face-to-face, be positioned at cold passage 2 belows can be through the floor openings of air-conditioning cold air, the door 4 that is positioned at the ceiling 4 at top and is positioned at cold passage 2 two ends; The wherein said ceiling 4 that is positioned at the top is provided with skylight 6 and monitoring unit 7; According to the testing result of monitoring unit 7, through the unlatching in intelligent control appliance control skylight 6.Corresponding, rack 1 back-to-back arrangement constitutes the passage of heat 3.

Cold channel roof ceiling 4 can adopt accordion structure, can make its before installation or the dismounting after transport or put more convenient.
