Engineered Acoustic Enclosures for Chillers
Ever had a project stall because of unexpected noise complaints? Chillers may be the culprit.
Noise is frequently overlooked in the design of mechanical equipment, only becoming a problem once the equipment is installed and the neighbors start complaining. If the local authorities find that a site has violated noise ordinances, the situation needs to be remedied quickly to avoid legal action.

System Testing to Optimize Terminal Unit Acoustics
In many commercial HVAC systems, engineers pair VAV boxes, fan-powered boxes and fan coils with duct silencers to meet the acoustical requirements of a space. While all the components are tested to industry standards – AHRI 880 and AHRI 260 for terminal units and fan coils and ASTM E477-20 for silencers – the combination of these two categories in real-world installations isn’t always straightforward.

Choosing the Right Coil to Optimize Your System’s Performance
Air-to-water heat pump systems are highly efficient HVAC solutions, but optimizing their performance depends on addressing key factors – most notably, the hot water supply temperature (HWST). And when these heat pumps are paired with a VAV distribution system, it’s especially critical to select the correct coil configuration.
