Demand-controlled ventilation for air-tight homes

Aereco, demand controlled ventilation, indoor air quality

Aereco’s demand-controlled ventilation (DCV) system is said to have much lower energy usage than conventional systems. These systems are much cheaper to install than MVHR systems and also to have low maintenance costs. As homes have ever-lower air-leakage rates, Aereco is promoting its system with the slogan ‘in our rush to seal up our homes form the cold, let’s not forget we have to live in them’ (illustration).

DCV systems include humidity sensors on grilles that automatically react to occupancy and deliver only a trickle of air if no-one is there.

When humidity-sensitive technology is applied to air inlets and air-extract units, the cross-sectional area of the ventilation units is modulated according to the local relative humidity. When used on extract grilles in bathrooms and kitchens, pollutants are removed and mould cannot develop.

There are no filters, and the system is virtually maintenance free. A system can be planned into the life of a building and comes with a 30-year guarantee from Aereco.
