The invention concerns a supply air terminal device (10) and a method for regulating the airflow rate. The supply air terminal device (10) comprises a heat exchanger (11), with which a circulated airflow (L2) conducted from a room can be either cooled or heated. The supply air terminal device (10) comprises a mixing chamber (12), into which mixing chamber (12) the air chamber's (15) nozzles (16a1, 16a2 . . . 16an) or a flow gap (16) open to conduct a primary airflow (L1) into the mixing chamber (12), whereby the primary airflow (L1) from the nozzles (16a1, 16a2 . . . 16an) or through the flow gap (16) as a flow (Qs) will induce a circulated airflow (L2) from the room (H) to flow through the heat exchanger (11) into the mixing chamber (12). The combined airflow (L1+L2) is conducted into the room (H). The supply air terminal device (10) comprises a regulator (100) bypassing the nozzles (16a1, 16a2 . . . 16an) or the flow gap (16) to regulate an airflow (Q3) passing through the regulator (100), with which, depending on the purpose of use of the room, it is possible to regulate the total airflow (ΣQ) of the fresh primary air (Q3+Qs) supplied from outside the supply air terminal device.
Supply air terminal device (10), which comprises a heat exchanger (11), with which a circulated airflow (L2) conducted from a room can be either cooled or heated, and which supply air terminal device (10) comprises a mixing chamber (12), into which mixing chamber (12) an air chamber's (15) nozzles (16a1, 16a2 , , , 16an) or a flow gap (16) open to conduct a primary airflow (L1) into the mixing chamber (12), whereby the primary airflow (L1) from the nozzles (16a1, 16a2 . . . 16an) or through the flow gap (16) as a flow (Qs) induces a circulated airflow (L2) from the room (H) to flow through the heat exchanger (11) into the mixing chamber (12), whereby a combined airflow (L1+L2) is conducted into the room (H), wherein the supply air terminal device (10) comprises a regulator (100) bypassing the nozzles (16a1, 16a2 . . . 16an) or the flow gap (16) to regulate an airflow (Q3) flowing through the regulator (100), with which according to the purposes of use of the room it is possible to regulate the total airflow (ΣQ) of the fresh primary air (Q3+Qs) supplied from outside the supply air terminal deice.
Method for regulating the airflow rate in a supply air terminal device (10), which supply air terminal device (10) comprises a heat exchanger (11) in the body structure (13) context, and which supply air terminal device (10) comprises a mixing chamber (12), and that nozzles (16a1, 16a2 . . . ) or a flow gap (16) open into the mixing chamber (12) to conduct a primary airflow (L1) conducted from outside from the air chamber (15) into the mixing chamber (12), whereby the primary airflow (L1) will induce a circulated airflow (L2) from the room (H) to flow through the heat exchanger (11), with which heat exchanger the airflow (L2) from the room (H) is either cooled or heated, wherein the total air rate (ΣQ) of the fresh primary airflow Q3+Qs conducted from outside is regulated by regulating the regulator (100) bypassing the nozzles (16a1, 16a2 . . . 16an) and thus the airflow rate Q3 (1/s) through said regulator (100) into the room (H).
