The invention discloses a device for controlling uniform air supply of a static pressure box of a data center and an implementation method thereof. The device comprises static pressure sensors, a static pressure intelligent control box and accurate adjustable air supply floors; static pressure sensors are used for detecting current static pressure values of air supply openings in real time; the static pressure intelligent control box is used for receiving and calculating the static pressure values of the air supply openings detected by the static pressure sensors; the accurate adjustable air supply floors are used for receiving an instruction to adjust the air supply size and area of the air supply floors; and the static pressure intelligent control box comprises a main controller, an RS485 communication module, a human-computer interaction HMI and a power supply, and the main controller is used for adjusting and controlling the areas of the air supply openings in the accurate adjustable air supply floors. According to the device and the method, the rotating speed of blowers can be adjusted and the areas of the air supply openings can be controlled according to the static pressurevalues of the air supply openings of the air supply floors in a machine room so that that the uniformity of the air supply amount and the static pressure of each air supply opening can be guaranteed,and IT equipment in the machine room can be cooled rapidly.

Description

technical field [0001] The invention relates to the technical field of air-conditioning air supply control, in particular to a device for controlling the uniform air supply of a static pressure box in a data center and a method for realizing the same. Background technique [0002] In some traditional large and medium-sized data center computer rooms, the airflow organization of air-conditioning cooling usually adopts the cooling method of sending down and returning to the top. The cold air is passed through the space under the floor as a transfer channel, and then near the air inlet of the cabinet, through the open air supply floor, the cold air is directly blown to the air inlet of the cabinet to rapidly cool the IT equipment of the cabinet; the hot air discharged from the cabinet is due to With low density, it will rise upwards, and then be drawn back to the return air outlet of the air conditioner through the hot return air duct, thereby forming a thermodynamic circulatio...

Problems solved by technology

[0005] As the air supply distance increases, the wind resistance in the air supply direction is greater, the dynamic pressure decays quickly, and the static pressure is also very irregular. If cables, fire pipes, brackets, etc. are laid under the floor, the dynamic pressure loss of the air supply will increase; If the size of the air supply opening on the floor at the front end of the air supply is small, and the dynamic pressure at the end is large, it will all be converted into static pressure, and the air volume at the end will increase, and the air volume at the front end will be insufficient; the above factors may lead to uneven temperature distribution in the equipment room , It is easy to generate local hot spots and damage IT equipment, which is a taboo in the operation of the computer room; and in the early stage of construction of the computer room, the IT heat load is small, and the problem caused by uneven air supply is not prominent. When it gets dirty, the outlet air pressure will decrease, and the problems caused by insufficient and uneven air supply at the end will become more and more prominent

[0006] Nowadays, many traditional old computer rooms are seriously affected by the problem of uneven temperature. So far, no effective monitoring and solutions have been proposed.
