UNIT DESIGN AND OPERATING LOGIC

8
www.blaubergventilatoren.de
Komfort ERV EC DB S14
UNIT OPERATION MODES
Heat recovery mode: warm extract air from the room flows into the unit and is cleaned in the extract filter. Then the air is moved through the heat
exchanger and is exhausted outside with the extract fan.
Cold fresh air from outside flows into the unit, where it is cleaned in the supply filter. Then the air flows through the heat exchanger and is moved to
the room with the supply fan.
Supply air is heated in the heat exchanger by means of the extract air heat energy transfer to cold intake air. The air flows are fully separated while
flowing through the heat exchanger. Heat recovery minimizes heat losses, which reduces the heating costs in the cold season.
The enthalpy heat exchangers enables both heat and air humidity recovery. In the summer season the enthalpy heat exchanger cools down and
dehumidifies supply air and in the cold season warms it up and humidifies. The moisture vapour condensate generated by humid-laden extract air is
absorbed by the heat exchanger plates. The humidity and heat energy are transferred to the supply air and the microbes and odours are separated.
EXTRACT AIR
SUPPLY AIR
INTAKE AIR
EXHAUST AIR
Defrosting mode: the defrosting mode is designed for heat exchanger freezing protection and is activated on feedback from the freeze protection
temperature sensor in the exhaust air duct. Activation of the defrosting mode starts when the exhaust air temperature drops down to +3 ˚C. When
the exhaust air temperature exceeds above this temperature point, the unit reverts to the previous operation mode. In the defrosting mode only the
exhaust fan is turned off, the supply fan operates normally.
EXTRACT AIR

Summer cooling mode: a parts of the intake air bypasses the heat exchanger along the bypass air duct, the bypass damper is opened. The intake air
stream temperature remains constant. This operation mode is applicable for the unit modifications with a bypass damper.

Prior to the installation check the unit casing for any left-over foreign objects such as plastic film or paper.
While mounting the unit make sure to provide sufficient service access to the unit for maintenance and repair operations.
Keep the minimum distance between the unit and the ceiling 20 mm.
To attain the best performance of the unit and to minimise turbulence-induced air pressure losses connect a straight air duct section on both sides of
the unit.
Minimum straight air duct length:
• equal to 1 air duct diameter on intake side.
• equal to 3 air duct diameters on outlet side.
If the air ducts are not connected or the connected air ducts are too short, protect the unit parts from ingress of foreign objects.
Cover the spigots with a protecting grille or other protecting device with mesh width not more than 12.5 mm to prevent uncontrollable access to the
fans.

regular cleaning and the following operations:
1. Filter maintenance (3–4 times per year).
Contaminated filters increase air resistance in the system and reduce supply air volume.
The filters require cleaning not less than 3–4 times per year.
To replace the filters remove the access door on the service panel and remove the contaminated
filters. Then install the new filters and fasten the access door in the reverse order.
Contact the unit Seller to purchase new filters.
2. Heat exchanger maintenance (once per year).
Some dust may accumulate on the heat exchanger even in case of regular maintenance of
the filters.
To maintain the high heat exchange efficiency, clean the heat exchanger regularly using a
vacuum cleaner narrow nozzle.
To replace the heat exchanger remove the access door on the service panel and remove the
contaminated heat exchanger.
