Dirt Deposits around Ceiling Diffusers
Smudging is more commonly known among First Nations as a ceremonial burning of one or more medicines gathered from the earth. In the world of HVAC, smudging is a term used to describe dirt being deposited on the ceiling around a supply diffuser, a common problem in all types of buildings.

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.

Design Considerations for Natatorium Ventilation
Designing a ventilation system for a swimming pool can be tricky. For occupant comfort, these facilities require 40 to 60% relative humidity to be maintained year round. For swimmers, a humidity range of 50 to 60% is most comfortable. However, humidity levels below 50% can significantly increase energy consumption, while humidity levels above 60% can cause damage due to mold, mildew and condensation.

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:
