Abstract

The invention discloses a device for controlling the uniform air supply of a static pressure box in a data center and a realization method thereof. The device also includes: a static pressure sensor for real-time detection of the current static pressure value of the air supply port; a static pressure intelligent control box, It is used to receive and calculate the static pressure value from the air supply port detected by the static pressure sensor; the precisely adjustable air supply floor is used to receive instructions to adjust the air supply size area of ​​the air supply floor; the static pressure intelligent control box specifically Including: main controller, RS485 communication module, human-computer interaction HMI and power supply, the main controller is used to adjust and control the area of ​​the air outlet in the air supply floor; the invention detects the static pressure of the air supply outlet of the air supply floor in the machine room Size, adjust the speed of the blower, control the area of ​​the air outlet, ensure the air supply volume and static pressure of each air outlet are uniform, and quickly cool the IT equipment in the computer room.

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 plenum box in a data center and an implementation method thereof. Background technique [0002] In some traditional large and medium-sized data center computer rooms, the airflow organization of the air conditioner cooling usually adopts the cooling method of sending downward and upward. The cold air is passed through the space under the floor as a transfer channel, and then the cold air is blown directly to the air inlet of the cabinet through the perforated air supply floor near the air inlet of the cabinet to quickly cool the IT equipment of the cabinet; the hot air discharged from the cabinet is due to The density is small, it will rise up, and then be drawn back to the return air outlet of the air conditioner through the hot return air duct, thus forming a thermal circulation.

AI Technical Summary

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.
