Chiller and pump noise pollution and noise reduction
A chiller and several types of industrial pump were generating
considerable noise pollution, and causing complaint from local residents.
Our noise tests showed that about an 11 dBA noise reduction was
needed. The noise contained distinctive "hum" and "whistle"
types of sound, which were the main cause of annoyance and the prime
candidate for noise reduction.
Our noise tests identified the presence of some faults on both
the chiller and some of the pumps. The noise control solution that
we recommended was to rectify these faults and to make some changes
to the way that the chiller was operated at night in order to prevent
further nuisance and complaint. The installation cost of this noise
control solution was very low.
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, the number of
industrial noise pollution complaints due to such cooling systems
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. Engineering types
of solution that reduce the noise pollution at source often provide
a much higher noise reduction than common types of industrial noise
control solution. This is because the noise reduction performance
of common types of noise control solution, such as an acoustic screen,
acoustic barrier, etc, is poor at low frequencies. Engineering noise
control solutions that reduce the noise at source can be applied
to most cases of chiller and cooling system noise pollution.
Although a high noise reduction can be achieved once the equipment
is operational, the best time to solve noise pollution problems
with chillers, air condensers and cooling systems is prior to ordering
and installation. The cost of noise control is usually much less
if implemented at this stage. Please contact us for advice on this.
