As more and more cold storage facilities are built around cities, the noise generated by their refrigeration equipment has gradually attracted the attention of nearby residents. So, how loud is the noise from the cold storage? Will it affect daily life? How should we solve it?

Where does the noise come from? How big is it?

The main sources of noise in cold storage include:

Compressor: the core noise source, especially for large equipment, with obvious operating sound;
Condenser fan/cooling tower: installed outdoors, the sound of fan operation spreads far;
Evaporator fan: mainly affects the inside of the warehouse, and partially transmits to the outside.
At a distance of 1 meter near the device, the noise can reach 75-85 decibels, equivalent to the level of traffic noise on the street. However, most modern new cold storage facilities use low-noise equipment and frequency conversion technology, which significantly reduces noise.

How to control noise?

Common governance methods include:

Select low-noise and variable frequency equipment;
Install soundproof covers, mufflers, and sound barriers;
Install vibration reduction base to prevent vibration propagation;
Reasonable layout, keep high noise equipment as far away from residential areas as possible.

Summary

Cold storage noise is a preventable and controllable issue. By selecting advanced equipment, implementing effective sound insulation and vibration reduction measures, and scientifically planning, it is entirely possible to meet environmental requirements and reduce the impact on the surrounding area. If residents are troubled by noise, they can report to the environmental protection department and apply for testing to see if the noise exceeds the standard.
