ABSTRACT:

FIELD OF THE INVENTION
The invention concerns a supply air terminal device, which is used for conducting a mixture of primary air and circulated air into the room space. The primary air, preferably fresh supply air, is first conducted into the supply air chamber of the device and thence through nozzles into a mixing chamber. The primary airflow is used to induce a secondary airflow, that is, a flow of re-circulated air, from the room space. In the device solution, the secondary airflow and the primary airflow are combined in the mixing chamber, and the combined airflow is made to flow away from the device.
BACKGROUND OF THE INVENTION
So-called closed and open state-of-the-art supply air terminal devices are known. The so-called closed supply air terminal device is open from the bottom part of the device, whereby the re-circulated airflow L
2
is conducted below through the heat exchanger of the device into the mixing chamber. The said airflow is induced by supply airflow L
1
from the nozzles of the supply air chamber. From the mixing chamber, the combined airflow L
1
+L
2
is made to flow out and preferably sideways guided by flow-guiding plates.
Where the circulated airflow is cooled, directing of the airflow leaving the device has become a problem. In state-of-the-art solutions, the combined airflow L
1
+L
2
tends to leave the device downwards, although the aim is to direct the combined airflow L
1
+L
2
to the side horizontally and preferably at ceiling level.
OBJECTS AND SUMMARY OF THE INVENTION
In order to overcome the above-mentioned problem, in the solution according to the invention the supply airflow is directed from the nozzles of the supply air chamber in such a way that the flow meets obliquely an internal wall limiting the mixing chamber B
1
, which wall is located close to the heat exchanger. Thus, the central axes of the nozzles are obliquely at an angle &agr; in relation to the vertical axis y
1
of the device. The angle range &agr; is preferably between 5° and 15°, that is, 5°≦&agr;≦15°. With the described directing of the nozzles a desired throw pattern is achieved for the combined airflow L
1
+L
2
.
