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 (J1) will induce a circulated airflow to flow out of the room (H) through a heat exchanger (10). The circulated airflow (J2) joins the supply airflow (J1), whereby the combined airflow (J1+J2) 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 (J2). 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.

Description

    FIELD OF THE INVENTION
  • The invention concerns a device for treatment of indoor air.
    • BACKGROUND OF THE INVENTION
  • The state of the art knows supply air terminal devices, through which fresh supply air is conducted from a supply air chamber into a side chamber of the device. From the supply air chamber the air is led by way of nozzles into the side chamber, and said flow of fresh supply air induces a circulated air flow to flow through a heat exchanger. The combined airflow J1+J2 is made to flow further out of the device. In the heat exchanger, the circulated airflow J2 is either cooled or heated. The circulated airflow J2 is led from the room to join the fresh supply airflow J1. In the state-of-the-art solutions, the heat exchangers are delivered from the factory according to an order made in advance. Thus, the heat exchanger is manufactured and custom-made on an individual case basis, and said supply air terminal device and the related order for a heat exchanger structure are associated with various treatment steps in the various stages of the order.
  • So-called passive beams are also known, which are installed in the ceiling of the room space and which comprise nothing else than a heat exchanger, whereby the heated indoor air will circulate close to the ceiling and to the heat exchanger of the passive beam located there, which heat exchanger will cool the circulated air, which when cooled will flow down into the occupied zone of the room.
    • SUMMARY OF THE INVENTION
  • This application has realized how to form a heat exchanger structure of modules. Modules are of various lengths, and the client ordering the device may thus choose the combined length he desires, and no separate device-specific custom-making is needed. Much time and work in various stages will thus be saved and the total costs of the device will thus be more advantageous. Each basic module, that is, heat exchanger module, comprises tubes and fins or other such parts to transfer heat from the air through the fins into a heat carrier made to flow inside the tubes, or in an opposite direction. The modular structure also comprises so-called connection modules and end modules as well as supply modules, that is, tube modules.
  • According to the invention, the heat exchanger modules are of several different lengths: for the end modules and middle modules and also different types of tubes for the connection module and the tube module. Using the connection module for tubes it is possible easily to connect modules of different lengths to one another without needing any welded connection or other such. The scope of the invention also includes an embodiment, wherein instead of the connection module a welded or soldered connection is used between the modules to be connected.
  • The device for treatment of indoor air according to the invention is characterized by the features presented in the claims.
