Ventilator design
VENTILATOR OPERATION MODES
The ventilator has two operation modes:
Ventilation:
the ventilator runs either in extract or supply mode at a set speed.
In this mode, when two ventilators are installed, one of them supplies and the other one extracts the air.
Regeneration:
the ventilator runs in two cycles, 70 seconds each, with heat and humidity regeneration.
•
Cycle I.
Warm stale air is extracted from the room and flows through the ceramic regenerator, which gradually absorbs heat and
humidity. In 70 seconds, as the ceramic regenerator gets warmed, the ventilator is switched to supply mode.
•
Cycle II.
Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and is heated up to
the room temperature. In 70 seconds, as the ceramic regenerator gets cooled down, the ventilator is switched to air extract mode
and the cycle is renewed. If two ventilators are installed, they operate with opposite rotation directions in this mode. While one
ventilator supplies air, the other one extracts it.
