Claim:
Supply air terminal device ( 10 ) comprising: a supply air chamber ( 15 ), two heat exchangers ( 11 ) at both sides of the supply air chamber ( 15 ), two mixing chambers ( 12 ) between the heat exchangers ( 11 ) and the supply air chamber ( 15 ), into which mixing chambers ( 12 ) a primary airflow (L 1 ) is conducted from the supply air chamber ( 15 ) through nozzles ( 16 a 1 , 16 a 2 . . . 16 a n ) or a flow gap ( 16 ), said primary airflow (L 1 ) inducing a circulated airflow (L 2 ) to flow from a room (H) through each heat exchanger ( 11 ) into each mixing chamber ( 12 ), said circulated airflow (L 2 ) arriving at each heat exchanger ( 11 ) from the side and being heated or cooled in the heat exchanger ( 11 ), a covering plate ( 13 b ) closing the supply air terminal device ( 10 ) from below, the supply air chamber ( 15 ), the heat exchangers ( 11 ), the mixing chambers ( 12 ), as well as the nozzles ( 16 a 1 , 16 a 2 . . . 16 a n ) or the flow gap ( 16 ) being located above the covering plate ( 13 b ), a discharge duct (A) being formed above each mixing chamber ( 12 ), said nozzles ( 16 a 1 , 16 a 2 . . . 16 a n ) or flow gap ( 16 ) directing the primary airflow (L 1 ) upwards, whereby a combined airflow (L 1 +L 2 ) comprising the primary airflow (L 1 ) and the circulated airflow (L 2 ) is directed from each mixing chamber ( 12 ) through the discharge duct (A) obliquely upwards to the room (H) at a level of a ceiling ( 15 a ) of the supply air chamber ( 15 ), a regulator ( 100 ) fitted in the ceiling ( 15 a ) of the supply air chamber ( 15 ), said regulator ( 100 ) regulating a by-pass airflow (Q 3 ) flowing from the supply air chamber ( 15 ) to the room (H), said by-pass airflow (Q 3 ) bypassing the nozzles ( 16 a 1 , 16 a 2 . . . 16 a n ) or the flow gap ( 16 ), said regulator ( 100 ) making it possible, according to the purpose of the use of the room, to regulate the total airflow (ΣQ) of fresh primary air comprising the by-pass airflow (Q 3 ) through the regulator ( 100 ) and the primary airflow (Qs) through the nozzles ( 16 a 1 , 16 a 2 . . . 16 a n ) or the flow gap ( 16 ), the by-pass airflow (Q 3 ) being discharged from the supply air chamber ( 15 ) directly into the room to a space above the ceiling ( 15 a ) of the supply air chamber ( 15 ) and conducted further with the combined air flow (L 1 +L 2 ) to the room (H), whereby said regulator ( 100 ) makes it possible, according to the purpose of the use of the room (H), to regulate the by-pass airflow (Q 3 ) flowing through the regulator ( 100 ) to the room (H) and in this way the total airflow (ΣQ) of fresh primary air flowing into the room (H), said total airflow of fresh primary air comprising the by-pass airflow (Q 3 ) flowing through the regulator ( 100 ) to the room (H) and the primary airflow (Qs) flowing through the nozzles ( 16 a 1 , 16 a 2 . . . 16 a n ) or the flow gap ( 16 ) to the room (H).
