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.
