Bringing Design to Reality
Back in 2022, a mixed-use building in the Downtown East Village neighborhood of Calgary, AB, managed by the Calgary Housing Corporation, was identified as violating the city’s noise bylaws due to excessive noise emitted by its air-conditioning condensers. To address the issue, the city had initially planned to purchase and relocate new low-noise variable refrigerant flow (VRF) condensers.

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.

Best Practices for a Successful Mechanical System Design
Understanding how much space a fan coil unit needs is imperative for mechanical system design. Incorrect assumptions can create deviations between contract documents and finished buildings, which can lead to change orders and increased project costs for building owners. The type of fan coil unit, the options it is configured with and the overall design of the building’s HVAC system all influence the final installation requirements.

A Simple Approach to Air Distribution for Large Spaces
In the world of air distribution, a drop box is a plenum with multiple air outlets that is connected directly to an air handling unit (AHU) by a short run of ductwork. A drop box can be an effective way to deliver a substantial volume of conditioned air to large, enclosed spaces.
