Brig HRV 120 (170)
STRUCTURE AND OPERATING LOGIC
The unit has the following operating logic (g. 2):
Warm stale extract air from the room ows through the air ducts to the unit, is puried
in the extract lter and is supplied to the heat recovery core and exhausted outside by exhaust fan.
Clean cold air from outside is moved by supply fans to the unit where it is puried through the supply
lter. Then clean air ows through the heat recovery core and is supplied to the room by supply fan.
Thermal energy of warm extract air is transferred to clean intake fresh air and warms it up.
The extract and intake air ows are fully separated during heat recovery which excludes any transfer
of odors and pathogens to supply air. Heat recovery minimizes thermal energy losses, energy demand
and heating costs.
