Abstract
The present invention relates to a decentralized hybrid ventilation. The ventilation system comprises a housing having an inlet channel and an outlet channel. A first fan is arranged in the inlet channel for providing an airflow into the room and a second fan is arranged in the outlet channel for providing an airflow out of the room. A heat exchanger and filters are arranged in said channels for exchanging heat between and for filtrating air flowing into the room and air flowing out of the room. Furthermore, the ventilation system comprises a first and a second service door each providing, when open, an opening between the room and one of said channels to diverge the airflow from primarily flowing through the air filters and/or heat exchanger. The ventilation system also comprises a control system configured for switching between different modes of operations.
