DESIGN 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, where it is ltered, then air ows through the heat
exchanger and is exhausted outside by the extract fan through the air ducts.
Clean cold air from outside is moved by the supply fan to the supply lter of the air handling unit. Then ltered air ows through the
heat exchanger and is moved by the supply lter to the room through the air ducts.
Heat energy of warm extract air is transferred to clean intake fresh air from outside and warms it up. Heat recovery minimizes thermal
energy losses, energy demand and operating costs for air heating accordingly.
The air handling unit construction includes specially designed and sealed service panels for repair and preventing operations. The
terminal block on the side panel incorporates a terminal block. Power and ground cables are connected to the terminal block through
the sealed electric lead-ins.
