Air-conditioning system fan control method, air-conditioning system and computer-readable storage medium

Abstract

The invention provides a fan control method for an air conditioning system, the air conditioning system and a computer readable storage medium. The method comprises the steps that first rotating speeddifferences of all fans in the air conditioning system in the previous cycle are calculated; second rotating speed differences of all fans in the current cycle are calculated; the actual rotating speed difference of each fan is calculated according to the corresponding first rotating speed difference and the corresponding second rotating speed difference of the fan; and the rotating speed targetvalue of each fan is obtained, the actual rotating speed control value of the fan is calculated according to the rotating speed target value and the actual rotating speed difference of each fan, and the fans are controlled to run according to the actual rotating speed control values. The invention also provides the air conditioning system for achieving the method and the computer readable storagemedium. By means of the fan control method, individual control over the rotating speed of the fan can be achieved, and it is ensured that the temperatures of various regions of a data center are substantially equal.

Description

technical field [0001] The present invention relates to the control field of an air conditioning system, and in particular, relates to a method for controlling a fan of an air conditioning system, an air conditioning system applying the method, and a computer-readable storage medium. Background technique [0002] With the rapid development of the communication industry, data centers are becoming more and more popular. Generally, a data center is provided with a large number of servers, and these servers generate a large amount of heat during operation. Because the server has a large number of electronic devices, these electronic devices are very sensitive to the operating temperature. Once the temperature of the server is too high, the performance of the electronic devices will be affected, and even the server cannot work normally, affecting the communication of a large number of users. [0003] Therefore, an air conditioning system needs to be installed in the data center t...

Problems solved by technology

[0004] However, since the temperature of each area in the data center is not exactly the same, especially in the vertical direction, the temperature difference of each area may be large

Because the hot air flows upwards and the cold air flows downwards, if each fan operates at the same speed, the temperature of the air supply in the vertical direction may be quite different, resulting in uneven temperature of the air supply, thus making the data The air flow in the center is chaotic and the cooling efficiency becomes low

[0005] In addition, because the existing air conditioning system often does not consider the temperature of the return air when determining the speed of the fan, that is, the speed of the fan is not controlled according to the temperature of the return air, resulting in uneven temperatures in various areas of the data center

In areas with high temperature, the temperature of the server may be too high and affect the work of the server. Therefore, it is necessary to control the speed of each fan separately to ensure the uniformity of the temperature in the data center
