How HVLS Fans Help Save Money: Destratification
What Is Destratification?
In the industry, destratification usually means mixing of air layers, also called thermal destratification. This is a process in which temperature layers are to be eliminated by continuous air movement.
Depending on the ceiling height, there can be temperature differences of 3 to 10 degrees between the floor and ceiling in larger buildings, as warm air always moves upwards due to the physics involved. Thermal destratification involves mixing the air in the room to remove the layers of air and to bring the warm air below the ceiling to the floor space.
What Is the Most Cost and Energy Efficient Way to Achieve Destratification?
If you want to use the warm air under the ceiling for your building in winter and avoid heat loss through air stratification, you must consider HVLS fans. These big (3.6 to 7.3 meters in diameter) fans move large volumes of air at very slow speeds (high volume low speed), thus ensuring thermal destratification.
The Advantages of HVLS Fans
In winter thanks to destratification with the HVLS fan, the heating system has to provide less heating power, as heat accumulations under the ceiling are avoided and the heated air is brought to the floor space. This saves money.
