Combining the Benefits of Chilled Beams and Displacement Ventilation
Chilled beam systems use the heat transfer capabilities of water to provide sensible cooling to a space. As we’ve discussed previously on the blog, when the system is in cooling mode, the induction process facilitated by the chilled beam nozzles causes warmer room air to mix with the colder primary air, providing the space with supply air with temperatures at 62°F to 66°F – much warmer than the 55°F supply air provided by conventional cooling systems.

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 contaminants 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.
