  • Ventilating Device with Alternating Airflows
    Publication number: 20170336150
    Abstract: The application relates to a ventilation device adapted to alternately direct a first and a second airflow to a first and a second heat-absorbing body in order to achieve a heat transfer between the two airflows. The device comprises a first and a second integral connection element adapted to allow communication with the first and the second heat-absorbing body, and a third and a fourth integral connection element adapted to allow conduction of the first and the second airflow to and/or from the device.
    Type: Application

  • Ventilation device with alternating airflow
    Patent number: 9470432
    Abstract: The application relates to a ventilation device adapted to alternately direct a first (3) and a second (5) airflow to a first (7) and a second (9) heat-absorbing body in order to achieve a heat transfer between the two airflows. The device comprises a first (11) and a second (13) integral connection element adapted to allow communication with the first and the secondheat-absorbing body, and a third (15) and a fourth (17) integral connection element adapted to allow conduction of the first and the second airflow to and/or from the device. The device further comprises an airflow control arrangement (19) connected with the integral connection elements via control arrangement openings and adapted to alternately direct the airflows to the respective integral connection elements.
