Creating Comfort, Efficiency and Sustainability with VAV Diffusers
High performance air systems demand modern design approaches with leading-edge
products and technology in order to optimize comfort and reduce energy consumption. A
comfortable environment is achieved by providing the smallest possible zones of temperature
control, allowing for individual temperature distribution and better air movement. Reduction
in energy is realized by designing a low-pressure HVAC system that allows for maximum
turn-down while maintaining temperatures.

Consider Various Pressure Control Methods in a VAV System
All diffusers become noisier with higher pressures at their inlet and this is true for VAV diffusers. Pressure is often reduced by the use of a balancing damper or terminal unit, but VAV diffusers are unique as they have a built in VAV damper that can close down to a minimum flow.

Inlet Effects
ASHRAE Standard 70
guidelines are in place so that ideal conditions are present during GRD testing
and to ensure the testing is repeatable. It is important to note that the performance
published in the
Price catalog
is based on these ideal conditions outlined in ASHRAE 70 and that
any field modifications can affect the performance of the outlet. There are five common field conditions and their influence on the air pattern of a given diffuser:
