Exploring the Inner Workings of Mechanical VAV Diffusers

In a previous blog post, we discussed variable air volume (VAV) diffusers and how these simple devices create small-zone comfort. VAV diffusers are available in two basic types: mechanical (thermal) and digital (electric). In this post, we take a closer look at the mechanical version, which requires no electrical or pneumatic connections and is powered by the temperature of the air.

A CFD Classroom Case Study

Obtaining efficient ventilation with overhead mixing systems for applications in heating climates can be a challenge. Not only does the positive buoyancy of the supply air work against the air distribution system, but most overhead mixing systems are designed with low supply air volumes (relative to cooling) and high supply air temperatures (more than 15°F above room temperature).

Unlimited Options for Your Design

In this blog series, we’re discussing how to achieve excellent indoor air quality without sacrificing the aesthetics of a space. Part one of the series looked at how long, continuous lengths of linear slot diffusers can integrate overhead mixed air distribution into highly architectural spaces, and part two dug deeper into the border style options available to achieve the desired appearance for a wide variety of applications.

Architects and Engineers No Longer Need to Choose Between Performance and Design

Air distribution is a necessary part of any well-designed indoor space. The HVAC system is used not only to provide heating and cooling in our buildings but also as a source of fresh, clean air. In the case of highly architectural spaces, how can air distribution be effectively integrated into the built environment without negatively impacting the overall appearance and feel of the architectural design?
