Noise Pollution Solution to Control Chiller & Pump Sound

A chiller and several types of industrial pump were creating a noise pollution problem. An urgent solution was required to control the sound because the equipment was causing a considerable number of complaints from local residents. Our noise tests showed that the noise pollution solution had to provide an 11 dBA noise reduction to reduce the sound to an acceptable level and avoid further noise nuisance complaints. The chiller and pump sound contained a distinctive “hum” and “whistle”, which were the main cause of annoyance and the main priority for noise reduction.

Our noise tests identified the presence of some faults on the chiller and some of the pumps. The solution we recommended to control the noise pollution was to rectify these faults and also to change the way the chiller operated at night. This remedy successfully resolved the noise problem. The installation cost of this noise pollution solution was very low.

How to reduce noise pollution from air conditioner or condenser

Noise Pollution Control for Chillers and Air conditioners

Chiller, air conditioner and air condenser units are a common cause of industrial noise pollution. Because they need to exhaust hot air to atmosphere, they are normally situated outside. Because houses are increasingly being built closer to factories and other commercial companies, the number of complaints about industrial noise pollution from such cooling systems is increasing. Frequently, not enough consideration is given to the prevention of noise pollution when installing noisy equipment outdoors.

Often, the noise pollution generated by this type of industrial equipment is dominated by a low frequency drone or hum from the chiller compressors and / or the cooling fans. Advanced or engineering solutions that reduce the noise pollution at source often provide a much higher sound reduction than common industrial noise control solutions. This is because the sound reduction performance of common noise pollution solutions, such as an acoustic screen, acoustic barrier, etc., is poor at low frequencies. Advanced or engineering noise control remedies that reduce the noise pollution at source can be applied to most chiller and cooling system sound problems.

Prevention of Noise Pollution

Prevention of noise pollution is better than cure. Although a high noise reduction can be achieved once the equipment is operational, the best time by far to control noise pollution problems on chillers, air condensers and cooling systems is prior to ordering and installation. The ease and cost of noise pollution control is usually considerably lower if implemented at this stage.
