Why choose ventilation system D?
With a type D central ventilation system, both supply and extraction are done mechanically. The big advantage of this system is that is enables heat recovery. This happens with the use of a heat exchanger: the cold supply air is heated in the heat exchanger by the warm return air. This greatly reduces heat loss.
Main advantages
A system D is also called balanced ventilation, because ideally the total supply flow is equal to the total extracted flow.
The main advantages of this balanced ventilation with heat recovery are:
- Immediate extraction to outside of polluted air and moisture
- Continuous supply of fresh air
- Correct ventilation with the right amount of air, regardless of weather conditions.
- Low energy bills thanks to heat recovery
