The invention relates to a ventilation device (1) adapted to control the airflow paths of a first (3) and a second (5) airflow to alternately flow to or from a first and a second heat-absorbing body in order to achieve a heat transfer between the two airflows. The device comprises a first airflow channel (7) adapted to be connected with and lead an airflow to or from the first heat-absorbing body and a second airflow channel (13) adapted to be connected with and lead an airflow to or from the second heat-absorbing body. |
