When it comes to commercial HVAC air distribution systems, single-duct VAV systems with hydronic reheat are one of the most popular in North America. As decarbonization and electrification efforts continue to impact the built environment, it is critical to maximize the efficiency of these systems and reduce their natural gas usage.

A variable air volume terminal unit, or VAV box, provides space-specific heating, ventilation or air-conditioning to individual zones within a larger indoor environment. The most common VAV box is a single-duct terminal unit, which regulates the volume of air that each space requires by adjusting a damper with an automated controller and actuator. VAV terminals often include additional components such as hydronic or electric heating coils and fans equipped with variable-speed motors.

Pressure drop – the difference in pressure between two points in a fluid-carrying system – is one of the most critical design considerations for air distribution equipment in the HVAC industry. The problem with pressure drop for terminal units is that there are a number of metrics that are often confused with one another despite referring to different performance variables. These include static pressure drop, velocity pressure drop, pressure drop associated with acoustics and pressure drop associated with accessories.
