Exhaust Fans with heat pump

The AWN Eco+ is a compact and fully integrated exhaust air heat pump. Here, the ventilation unit and the heat pump are combined in one. This components’ closeness allows a direct transmission of the exhaust air heat to the refrigerant which enhances the device efficiency and energy saving. The ventilation adapts the airflows according to the needs in the dwelling thanks to Aereco’s humidity-sensitive exhaust air system: the on-demand management is ensured at any time.

The heat provided throughout the year is then released by the heat pump directly to the heating water of the building heating system. The AWN Eco+ drastically reduces the energy load for heating water.

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.

In this version, AWN can be associated with third-party heat pumps via a brine buffer. The AWN Basic is a combination of an air exhaust module and a heat exchanger to ensure heat recovery.
