Exhaust fans with heat recovery


Exhaust air heat recovery (AWN) with heat pump for the on-demand exhaust air system

AWN Connect combines AWN Basic with Connect WP, a brine / saltwater / water heat pump designed specifically for AWN. While the AWN Basic is installed where the exhaust ducts end – above or under the roof – the Connect WP is designed for indoor installation and can be placed in the boiler room.

On the cold source side, the Connect WP cools a brine circuit up to 2 ° C and feeds the cold brine to the AWN Basic heat exchanger using an integrated feed pump. The heat is extracted from the stale air and returned to the heat pump. The heat pump raises the temperature level of the heat produced and makes it available the whole year through the heating water to the building’s heating system.
