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 (Y<SUB>1</SUB>) of the device. In the device, the supply air chamber ( 11 ) includes nozzle apertures ( 12 a<SUB>1</SUB> , 12 a<SUB>2</SUB> , . . . , 12 b<SUB>1</SUB> , 12 b<SUB>2 </SUB>. . . ) to conduct fresh supply air into a side chamber (B<SUB>1</SUB>) and to induce a flow of circulated air (L<SUB>2</SUB>) from the room space through the heat exchanger ( 14 ) into the side chamber (B<SUB>1</SUB>). 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 (L<SUB>1</SUB>) and the circulated air flow (L<SUB>2</SUB>) for controlling in which ratio there is fresh air (L<SUB>1</SUB>) and circulated air (L<SUB>2</SUB>) in the combined air flow (L<SUB>1</SUB>+L<SUB>2</SUB>). |
