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.

Removal of Particulate in Supply Air
Air filters are an essential part of any HVAC system to remove particulates in the supply air that would otherwise be harmful to the building occupants, or build up in the ductwork or equipment. They are also an essential part of air moving devices such as terminal units, fan coils and air handlers as they remove dirt that would otherwise cause coil blockages and fan wheel imbalances.

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.
