step A: detecting the current static pressure value of an air supply outlet in real time through a static pressure sensor associated with the precision air conditioner, and uploading the data of the detected static pressure value to a static pressure intelligent control box;
and B: the static pressure intelligent control box judges the maximum static pressure value and the minimum static pressure value in the static pressure values detected by the static pressure sensor, calculates the difference value between the maximum static pressure value and the minimum static pressure value, and judges the size of the difference value and a preset threshold value;
and C: when the difference value is larger than a preset threshold value, a main controller in the static pressure intelligent control box adjusts and controls the area of the air outlet which is adjusted gradually and controlled to be the largest in the accurate adjustable air supply floor and the area of the air outlet which is adjusted gradually and controlled to be the smallest in the static pressure;
a plurality of static pressure sensors are arranged on the air supply cold channel corresponding to each precise air conditioner, and the static pressure sensors are used for carrying out static pressure detection at the same time;
the step B further comprises the following steps:
when the maximum value and the minimum value of the static pressure values detected by the plurality of static pressure sensors associated with the precision air conditioner within a certain time are smaller than a preset threshold value, calculating the static pressure average value of all the static pressure values detected by the plurality of static pressure sensors associated with each precision air conditioner;
the step C further comprises the following steps:
when the static pressure average value is smaller than the minimum air outlet static pressure value, controlling the related air conditioner fan to increase the rotating speed so as to increase the air volume of the blower, and controlling the static pressure average value to be larger than the minimum air outlet static pressure value;
the accurate adjustable air supply floor is provided with a minimum guaranteed area opening degree, an adjustable lower limit air supply area is guaranteed, and the small area is not allowed to be adjusted to be zero infinitely.
5. The method of controlling data center plenum uniformity according to claim 4, further comprising, prior to step A:
and S, arranging a plurality of air supply static pressure sensors under an accurate adjustable air supply floor of the machine room in advance, wherein the air supply static pressure sensors are connected in an RS485 communication mode.
6. The method of controlling data center plenum uniformity according to claim 5, wherein said step S further comprises: connecting a plurality of precise air conditioners in a machine room through RS485 communication and connecting the precise air conditioners to a static pressure intelligent control box; and the main controller is in networking communication with all the precise air conditioners through RS 485.
