Destratification explained...

Thermal stratification affects all buildings and has been labelled as “the single biggest waste of energy in buildings today.’ - DTE Energy

Hot, lighter air rises towards the ceiling. Cool air falls to the floor. The result is a dramatic temperature between the floor and ceiling.

The major negative consequence of thermal stratification is a HVAC system to over-deliver on both heating and/or cooling to resist the effects on thermal stratification.

Consequently, energy bills are much higher and internal environments rarely meet expectations. The higher the ceiling the more likely a building will suffer from extreme temperature differences.

Wasted heat will inevitably rise to the ceiling or roof space serving no purpose and vastly increasing heat loss through the roof structure. Conversely, heavier cooled air which is more difficult to distribute is wasted by sinking to low points and becoming trapped in difficult to circulate areas.

Airius destratification fans are installed at ceiling height, sending air down to the floor in a tight, slow-moving column. 

When this reaches the floor, it radiates 360 outwards across the floor until it hits a vertical surface and/or air coming from neighbouring Airius fans and then it rises back up towards the ceiling.

As this air rises it entrains back into the descending column which creates millions of tiny vortices, making the air move at the same speed throughout the whole interior space creating a balance of temperature.

This process is achieved using minimal air movement, near silent operation and nominal power requirements. Savings on average are between 20 - 50%, although higher levels have been recorded (See Lush Cosmetic Case Studies).

Benefits: 20%- 50% energy savings | 0ºC - 2ºC temperature variance | Low energy consumption (12W+) | Silent operation | Lightweight, small & unobtrusive | Avoids draught disturbance | Simple installation | BSRIA Tested | Full destratification achieved.

How will I benefit?

Thermal stratification is a natural phenomenon affecting all buildings in a dramatic imbalance of temperatures from floor to ceiling.

Thus difference occurs when hot air rises towards the ceiling or roof because it is lighter than then surrounding cool air.

In contrast, cool air falls to the floor as it is heavier and denser.

The main negative consequence of thermal stratification is Heating, Ventilation and Air Conditioning. (HVAC) systems over-deliver to continually replace the heat which has risen to the ceiling (0.5ºC - 2ºC) per meter on average) in order to maintain set temperatures at floor level.

Conversely, heavier cooled air which is more difficult to distribute is wasted by sinking to low points in a building or by becoming trapped in difficult to circulate areas. 

Airius work alongside all types of heating and cooling equipment and are an extremely efficient replacement for duct work.
