Document Type and Number:
WIPO Patent Application WO/2021/223476
Kind Code:
A1
Abstract:
The present invention relates to the field of machine room equipment, and particularly provides a machine room ventilation floor and a control method therefor, for solving the problem of uneven air supply in a machine room. The machine room ventilation floor comprises a plurality of ventilation sub-floors which are spliced, ventilation holes are formed in fixed plates of the ventilation sub-floors, moving baffles and the fixed plates are stacked up and down, and the moving baffles can slide with respect to the fixed plates so as to adjust the ventilation area of the ventilation holes. The control method comprises: obtaining the current ventilation quantity of ventilation sub-floors and the average ventilation quantity in the whole machine room, and determining whether the current ventilation quantity is greater than the average ventilation quantity or not and whether the difference reaches a preset threshold or not; and if yes, reducing the ventilation area of the ventilation holes, and dynamically adjusting the air supply quantity of the ventilation sub-floors in the machine room to ensure evenness of the air supply quantity in various areas in the machine room. Partial hot spots are avoided, and the reliability of server running is improved. An air conditioning unit runs under the appropriate rotating speed and air outlet static pressure, even cooling of a server can be guaranteed, and high-speed running of a unit fan can be avoided.
