Description

The invention relates to a device for treating room air.

Supply air devices are known in the art through which fresh supply air is led from the supply air chamber to the side chamber of the device. From the supply air chamber, air is led through the nozzles to the side chamber and this fresh supply air flow induces 10 recirculated air flows to flow through the heat exchanger. The combined airflow Ji + J2 continues to flow out of the unit. In the heat exchanger, the recirculated air flow J2 is cooled or heated. The recirculated airflow h is led from the room to the fresh inlet airflow Ji. Heat exchangers for state-of-the-art solutions are pre-ordered from the factory. Thus, the heat exchanger is made and customized on a case-by-case basis, and that ordering of the supply air device and the associated heat exchanger structure involves various processing steps at different stages of the order.

Also known as the ceiling of a room space are known. passive beams comprising 20 heat exchangers only, whereby the heated room air circulates up to the ceiling to a passive beam heat exchanger located there, which cools down the recirculation line and, when cooled, lowers down to the living area in the room.

In this application, it is realized to form a heat exchanger structure of modules 25. The modules are of different lengths and thus the subscriber of the device can pre-select the desired combination length and no separate device-specific customization is required. This saves a great deal of time and effort on the various steps, and thus the overall cost of the device is most advantageous. Each basic module,

The g module comprises tubes as well as lamellae or the like for transferring heat through the lamellae to the heat transfer medium flowing inside the tubes or in the opposite direction. The modular structure further comprises a so-called. connection modules and end modules, as well as inlet or tube modules.

According to the invention, the heat exchanger modules are of various lengths: the end-5 module and the middle module, and in addition different types for the pipe connection module and the pipe module. With the pipe connection module, modules of different lengths can be easily connected without the need for a weld connection or the like. Also within the scope of the invention is an embodiment in which a weld or solder joint between the modules to be connected is used instead of a connection module.

As shown in Fig. 1A, the device 100 for treating room air comprises an inlet air chamber 11 for supplying fresh air from outside through a conduit (not shown). The fresh air from the Tu-15 air chamber 11 is led through the nozzles 12ai, 12a2 ... to the mixing chamber S adjacent to the heat exchanger 10, whereby the fresh air stream J1 derived from the nozzles 12ai, 12a2 induces recirculated air flow J2 from room H to flow through the heat exchanger 10. The heat exchanger 10 either cools or heats the recirculated air stream J2.
