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 (L<SUB>2</SUB>) 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 ( 16 a<SUB>1</SUB> , 16 a<SUB>2 </SUB> . . . 16 a<SUB>n</SUB>) or a flow gap ( 16 ) open to conduct a primary airflow (L<SUB>1</SUB>) into the mixing chamber ( 12 ), whereby the primary airflow (L<SUB>1</SUB>) from the nozzles ( 16 a<SUB>1</SUB> , 16 a<SUB>2 </SUB> . . . 16 a<SUB>n</SUB>) or through the flow gap ( 16 ) as a flow (Q<SUB>s</SUB>) will induce a circulated airflow (L<SUB>2</SUB>) from the room (H) to flow through the heat exchanger ( 11 ) into the mixing chamber ( 12 ). The combined airflow (L<SUB>1</SUB>+L<SUB>2</SUB>) is conducted into the room (H). The supply air terminal device ( 10 ) comprises a regulator ( 100 ) bypassing the nozzles ( 16 a<SUB>1</SUB> , 16 a<SUB>2 </SUB> . . . 16 a<SUB>n</SUB>) or the flow gap ( 16 ) to regulate an airflow (Q<SUB>3</SUB>) passing through the regulator ( 100 ), with which, depending on the purpose of use of the room, it is possible to regulate the total airflow (SigmaQ) of the fresh primary air (Q<SUB>3</SUB>+Q<SUB>s</SUB>) supplied from outside the supply air terminal device.
