Abstract

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 . . . 16a_n) 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 . . . 16a_n) or through the flow gap (16) as a flow (Q_s) 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 . . . 16a_n) 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+Q_s) supplied from outside the supply air terminal device.
