All indoor spaces require the introduction of fresh outdoor air to replace the stale indoor air.
It costs money to heat and cool this outdoor air
The stale indoor air has already been heated or cooled
When the unit is OFF the dampers close which isolates the building from the outside air.
When the unit is ON the 2 energy cores take turns either extracting energy from the exhaust air or adding energy to incoming outdoor air.
The unit's controller automatically adjusts the internal damper positions every 60 seconds which changes which energy recovery core is recovering energy and which core is adding energy.
The Tempeff Solution:
Extracts a consistent, high percentage of energy from the indoor air before it is exhausted outside.
Up to 90% of the energy from the air being exhausted is extracted and added to the fresh outdoor air.
This significantly reduces the amount of heating and cooling that needs to be used to temper the incoming air.
