A Flexible, Localized Air Handling Solution

The fan column is a vertical fan unit designed to discharge air into a raised access floor plenum. The unit may be likened to an air handler as it mixes filtered, cooled return air with pre-treated outside air typically from a dedicated outdoor air system (DOAS) to achieve the design supply air temperature, then discharge the mixed air into the raised access floor plenum.

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.

The Benefits of Displacement Ventilation and Chilled Beams for Efficiency

The United States Environmental Protection Agency (EPA) defines a high performance school as energy and resource efficient. Creating a high performance school is not difficult, but it requires an integrated, “whole building” approach from the beginning of the design process.

Energy Efficient Ventilation Effectiveness and Thermal Comfort

Displacement ventilation provides low velocity air at around 65°F that relies on buoyancy forces to drive the air motion. Supply air spreads across the floor until encountering thermal plumes from heat sources that naturally drive the clean, conditioned air up through the breathing zone. Heat and particulate are carried up to high-level return or exhaust grilles instead of getting recycled through the space. The result is high ventilation effectiveness and improved thermal comfort delivered in an energy efficient manner.
