Economizers are often the unsung heroes of HVAC systems, allowing units to use outdoor air for cooling inside buildings.
How do economizers work?
Economizers use outside air to ventilate or cool the building.
If the air temperature outside is cool enough, the economizer uses that air to ventilate and cool the building (which is why some refer to it as "free cooling"). Not only does this save energy, but it also helps extend the life of the equipment- a win-win!
How can the campus save energy with economizers?
The Energy Conservation Office tries to schedule economizers to maximize energy savings by looking at buildings' HVAC schedules and outside temperatures.
