Device For Treatment Of Indoor Air

Abstract

The invention concerns a device ( 100 ) for treatment of indoor air. The device ( 100 ) comprises a supply air chamber ( 11 ) and from this nozzles ( 12 a 1 , 12 a 2 . . . ) or a nozzle gap ( 12 ) to make a flow of fresh supply air flow out of the supply air chamber, which flow (J 1 ) will induce a circulated airflow to flow out of the room (H) through a heat exchanger ( 10 ). The circulated airflow (J 2 ) joins the supply airflow (J 1 ), whereby the combined airflow (J 1 +J 2 ) is made to flow out of the device. In the device ( 100 ) its heat exchanger ( 10 a 1 , 10 a 2 ; 10 ) is used to either cool or heat the circulated airflow (J 2 ). The device ( 100 ) for treatment of indoor air may also be a so-called passive beam, which can be fitted close to the ceiling of the room space (H), whereby the heated air is cooled by the heat exchanger ( 10 ) of the passive beam ( 100 ) as it ascends in the room space approaching the heat exchanger ( 10 ), from which upon being cooled it will descend back into the occupied zone of the room space (H). According to the invention, the heat exchanger ( 10, 10 a 1 , 10 a 2 ) is a modular structure, which comprises several optional different heat exchanger modules ( 14 a 1 , 14 a 2 , 14 a 3 , 14 a 4 , 14 a 5 ), which can be connected to one another in order to form a heat exchanger structure and a device structure of the desired length.
