Ventilation
The ventilation system is placed outside the house and provides filtered conditioned air to the child's bedroom, through insulated pipes mounted in a window opening. The window opening was built specifically for this purpose in form of a thermo plate replacing the window glass. The unit provides the bedroom with at least 2-3 air changes per hour
Placebo Ventilation
The placebo unit (DUPLEX 370) is a completely similar installation to the active ventilation unit, but it only recirculates the air in the room instead of replacing it with fresh conditioned air.
