Control Strategies to Optimize Your System

VAV diffusers help keep rooms comfortable using an individual thermostat and a built-in damper to create small zones of control. The amount of air provided by the VAV diffuser is based on three factors: the temperature in the room, the room’s set point and the temperature of the supply air.

It is the higher pressure that makes diffusers noisy, and because of this, a method of pressure control should be used in every VAV diffuser system.

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.
