Case Study - Exhaust Fan Enclosure

Project: Commercial Heat Pump (London)

Noise Problem:

A commercial heat pump was emitting noise 20 dB(A) in excess of existing background noise levels.

Remit:

Reduce exhaust fan noise emissions by 20 dB(A) whilst maintaining airflow into and out of the Daikin units.

Result:

An insertion loss of 20 dB(A) with minimised visual impact.

Enclosure Design:

• Supply Air Louvres
• Exhaust Air Attenuators
