London hotel seeks solution for noisy air conditioning system

When a premier hotel located in Greenwich received complaints from guests regarding noise levels from the external air conditioning units, an immediate solution was required. In total, fifteen Mitsubishi VRF systems delivered heating and cooling to the hotel’s 157 guest rooms. This meant that a large number of clients could potentially be affected by sound emissions at any given time.

Following a detailed investigation, the first option outlined to our client was for us to install full acoustic attenuators to all condensing units, thus delivering a noise reduction of 12dB. However, as the disturbance was most noticeable at night a highly cost-effective alternative was for us to install a capacity control system, enabling the condenser fans to operate more quietly (by a further 5-7dB) – but at lower capacity – during periods of lower heating or cooling demand. read more
