  • Patent number: 7000688
    Abstract: The invention concerns a supply air terminal device (10) including side plates (12) and an air guiding part (13). A heat exchanger (14) is fitted in the device below a supply air chamber (11) for supply air in between air guiding parts (13) located on both sides of the central axis (Y1) of the device. In the device, the supply air chamber (11) includes nozzle apertures (12a1, 12a2, . . . , 12b1, 12b2 . . . ) to conduct fresh supply air into a side chamber (B1) and to induce a flow of circulated air (L2) from the room space through the heat exchanger (14) into the side chamber (B1). Using the heat exchanger (14) the circulated air may be either cooled or heated. The equipment includes a control device (15) for the induction ratio of the supply air flow (L1) and the circulated air flow (L2) for controlling in which ratio there is fresh air (L1) and circulated air (L2) in the combined air flow (L1+L2).

  • 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 . . .

  • Patent number: 6715538
    Abstract: The invention concerns a supply air terminal device (10) including a supply chamber (11) for the supply air and in the supply chamber (11) nozzles (12a1, 12a2 . . . ; 12b1, 12b2 . . . ), through which the supply airflow (L1) is conducted into a side chamber (B1) of the supply air terminal device, which side chamber is a structure open at the top part and at the bottom part. The supply air terminal device (10) includes a heat exchanger (14), which can be used either to cool or to heat the circulated airflow (L2). In the device solution, fresh supply air, which is conducted through the nozzles to the side chamber (B1), induces the circulated airflow (L2) to flow through the heat exchanger (14). The combined airflow (L1+L2) of supply airflow (L1) and circulated airflow (L2) is conducted out of the supply air terminal device (10). The supply air terminal device includes an induction ratio control device (15), which is used to control how much circulated airflow (L2) joins the supply airflow (L1).
