Abstract

The invention relates to the technical field of cooling towers, in particular to a cooling tower noise reduction method, system and equipment based on fan frequency conversion and a storage medium. The method comprises the steps that thermotechnical data are collected, and an air volume value needed for maintaining the current cooling effect is obtained based on the thermotechnical data; determining a frequency value corresponding to the air volume value, wherein the frequency value refers to the lowest frequency value required for maintaining the current cooling effect; obtaining an operation record of the cooling tower, and determining a fan frequency threshold value based on the operation record and the frequency value; the fan frequency threshold comprises a lower frequency threshold and an upper frequency threshold; performing noise reduction control on the cooling tower based on the fan frequency threshold value and a preset control strategy; the problem that the noise reduction effect is poor due to the fact that noise reduction equipment is single in noise reduction effect and cannot control a noise source can be solved. The noise source can be controlled, so that the noise reduction effect is improved.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to a noise reduction method, system, equipment and storage medium for cooling towers based on fan frequency conversion. Background technique [0002] Cooling towers can be seen everywhere in daily production. The large-scale use of cooling towers has also caused noise pollution to varying degrees, especially in large public buildings. The number of cooling towers installed is huge, and their high noise has a great impact on the life and work of surrounding residents. big. [0003] The noise sources of cooling towers mainly include fan noise, mechanical noise and falling water noise. Among them, the falling water noise is generated when the water spraying device of the cooling tower falls and collides with the accumulated water in the tower chassis. It has high frequency characteristics and is generally covered by the noise of the fan; the mechanical noise is the noise genera...
