How VentoVind
TM
works
Ventovind
TM
is a method for adaptive controlled ventilation that guarantees that the ventilation only
takes place when it benefits the attic space. The supply air system ensures ventilation at the right
times while establishing a positive pressure scenario of the attic that prevents the travel of moisture
up from the accommodation. The system works best if the attic is sealed as tightly as possible where
the aim is that all ventilation occurs via intended dampers and vents.
The VentoVind
™ system basically consists of a controlled
supply air fan and a mechanical or
motorised exhaust air damper. The supply fan is powered and speed controlled via a control unit
placed inside the attic. Sensors that measure the outdoor climate as well as the climate in the attic
are connected to the control unit. The control unit reads off the sensors and determines, via an
algorithm, whether the ventilation should be open or closed, and also controls the fan speed
accordingly. In this way, the ventilation is optimised to the temporary ventilation requirement and as
little energy as possible is consumed. The ventilation system is only operational when the moisture
conditions are beneficial for ventilation using outdoor air.
Auxiliary dehumidifier
To ensure sat

supplemented with a backup dehumidifier. The VentoVind™ system is set so that the dehumidifier is
