Abstract: The present invention relates to an induction supply air terminal device where primary air flow is used to induce a secondary air flow wherein the nozzles are provided in the form of a cluster arrangement, comprising one or more clusters of three or more nozzles each. The clusters can be arranged according to predetermined patterns depending on the pattern of air induction that is desired.

Abstract: The supply air unit (100) comprises a supply air chamber (10), at least one mixing chamber (20a, 20b), which opens into the air-conditioned room space, nozzles (60a, 60b), through which a fresh airflow (L1) is conducted from the supply air chamber (10) into the mixing chamber, a first heat-transfer unit (A), which comprises at least one heat exchanger (30a, 30b), through which a circulated airflow (L2) is conducted from the room space into the mixing chamber. The supply air unit also comprises a second heat-transfer unit (B), which is formed by at least one radiating element (50), which has a radiating surface (51), to which heat is transferred from the air-conditioned room space for cooling or from which heat is transferred into the air-conditioned room space for heating, and which radiating surface also comprises openings, whereby the radiating surface becomes sound-absorbing.

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).

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).
