  • Supply air terminal device
    Patent number: 6769477
    Abstract: The invention concerns a supply air terminal device (10), which includes a supply air chamber (11) and therein nozzles (12a1, 12a2 . . . ), through which supply air is conducted into an internal side chamber (B1) of the device. In the device solution, the supply airflow (L1) induces a circulated airflow, that is a secondary airflow (L2), from the room space (H1) to flow through a heat exchanger (13) of the device into the side chamber (B1) to join the supply airflow (L1). In the device solution, the combined airflow (L1+L2) of supply air and circulated air is made to flow sideways from the device. The central axes (X1) of the nozzles (12a1, 12a2 . . .
