Central air conditioning cooling towers are used in many shopping malls and office machinery and equipment, the main role for central air conditioning cooling processing, but its at run time will produce a lot of noise, the noise affect the surrounding residents and users, so is there any provisions of the state of central air conditioning cooling tower noise standards?
The national noise emission value, there are relevant legal provisions, the most commonly used is the "social life noise emission standard" GB2237-2008. The specific content is as follows:
|Functional area classification||Period of time|
Noise classification criteria:
Category 0 is suitable for places that require extra quiet, such as senior nursing homes;
Category 1 standards apply to areas dominated by residential, cultural and educational institutions;
Category 2 standards apply to residential, commercial and industrial mixed areas and central business areas;
Category 3 standards apply to industrial areas;
4 types of standards apply to the areas on both sides of the main traffic lines;
Therefore, the central air conditioning cooling noise standard should be determined according to the specific situation
If it is a residential area, the central air conditioning of residential buildings, commercial and residential mixed areas, in accordance with 2 types of environmental protection standards to implement, that is, at night not more than 50 decibels, not more than 60 decibels in the daytime;
If it is in an industrial park or factory, it should be carried out according to the standard of category 3, no more than 55 decibels at night and 65 decibels during the day. As for the standard of class 0 and class 1, this kind of situation is relatively rare, and the standard of class 4 is not much, mainly applies to the standard of class 2 and class 3.
Therefore, if we need to control the noise of central air conditioning cooling tower, we can refer to the standard of class 2 or class 3, distinguish the area we are in, and then have a purpose to control, to achieve the requirements of environmental protection noise reduction. If there is a demand for noise reduction and management of cooling towers, you can contact us. We have many years of experience in noise management of cooling towers.
