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 (12a.sub.1, 12a.sub.2 . . . ) or a nozzle gap (12) to
make a flow of fresh supply air flow out of the supply air chamber,
which flow (J.sub.1) will induce a circulated airflow to flow out
of the room (H) through a heat exchanger (10). The circulated
airflow (J.sub.2) joins the supply airflow (J.sub.1), whereby the
combined airflow (J.sub.1+J.sub.2) is made to flow out of the
device. In the device (100) its heat exchanger (10a.sub.1,
10a.sub.2; 10) is used to either cool or heat the circulated
airflow (J.sub.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,
10a.sub.1, 10a.sub.2) is a modular structure, which comprises
several optional different heat exchanger modules (14a.sub.1,
14a.sub.2, 14a.sub.3, 14a.sub.4, 14a.sub.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
[0001] The invention concerns a device for treatment of indoor
air.
BACKGROUND OF THE INVENTION
[0002] 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 J.sub.1+J.sub.2 is
made to flow further out of the device. In the heat exchanger, the
circulated airflow J.sub.2 is either cooled or heated. The
circulated airflow J.sub.2 is led from the room to join the fresh
supply airflow J.sub.1. 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.
[0003] 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
[0004] 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.
[0005] 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.
[0006] The device for treatment of indoor air according to the
invention is characterized by the features presented in the
claims.

DETAILED DESCRIPTION OF THE INVENTION
[0016] FIG. 1A shows a view in principle of an embodiment of the
supply air terminal device according to the invention, wherein the
modular structure according to the invention is used. As is shown
in FIG. 1A, the device 100 for treatment of indoor air comprises a
supply air chamber 11, into which fresh air from outside is brought
through a tube set (not shown). From the supply air chamber 11 the
fresh supply air is conducted by way of nozzles 12a.sub.1,
12a.sub.2 . . . into a mixing chamber S beside the heat exchanger
10, whereby the flow of fresh supply air J.sub.1 conducted from
nozzles 12a.sub.1, 12a.sub.2 will induce a circulated airflow
J.sub.2 from the room H to flow through the heat exchanger 10.
Using the heat exchanger 10, the circulated airflow J.sub.2 is
either cooled or heated.
[0017] FIG. 1B shows another embodiment of the supply air terminal
device according to the invention. From supply air chamber 11a flow
J.sub.1 of fresh supply air is conducted upwards through nozzles
12a.sub.1, 12a.sub.2 . . . , and the circulated airflow J.sub.2
from room H is induced to flow induced by said flow J.sub.1 through
heat exchanger 10a.sub.1, 10a.sub.2 and further to join the flow of
fresh supply air J.sub.1. The combined airflow J.sub.1+J.sub.2 is
made to flow upwards and further to the side from the device and
back into the room space H. At the heat exchanger 10a.sub.1,
10a.sub.2 the room air is either cooled or heated as a circulated
airflow J.sub.2. FIG. 2 shows a heat exchanger 10, which comprises
a set of tubes 13 for the heat carrier and fins 14 or other such,
through which heat is carried into the room space or in an opposite

rises to approach the passive beam 100 and travels above the heat
exchanger 10 as shown by arrow J.sub.2, and it is further cooled in
heat exchanger 10 and it then descends back into the occupied zone.
In the summer time, the heat exchanger 10 can be used to cool the
circulated airflow J.sub.2. In this structure, too, the heat
exchanger 10 is one to be assembled of modules, whereby depending
on the length of the passive beam 100 the heat exchanger modules
can be chosen as desired in order to achieve the desired length of
the heat exchanger for the room application in question.
[0019] FIG. 2 shows a heat exchanger 10 formed of modules

[0020] FIG. 3 is a schematic view of a heat carrier circuit. The
heat carrier circuit comprises branches A.sub.1, A.sub.2 of the
tube set 13 for the heat carrier, whereby the heat carrier is made
to flow circulated by a pump P through heat exchangers 10a.sub.1
and 10a.sub.2. According to the invention, the heat exchangers
10a.sub.1, 10a.sub.2 are formed of a modular structure.
[0021] FIG. 4 shows a modular structure for a heat exchanger 10.
The heat exchanger comprises modules 14a.sub.1, 14a.sub.2,

module, the modules 14a.sub.2 and 14a3 are middle modules and the
module 14a.sub.4 at one end is an end module. Tube connecting
pieces, that is, connection modules 14a.sub.5, are used between the
modules. The tube connecting pieces 14a.sub.5 are parts, into whose
bushings the ends of tubes to be connected can be placed, whereby a
tight connection will be formed without using any soldering or
welding between the tubes. Said module 14a.sub.5 can also be
replaced by welding. Device complexes of the desired length can be
obtained by choosing modules 10a.sub.1 . . . 10a.sub.5 of the
desired length and type.
[0022] FIGS. 5A and 5B show a schematic and basic view of the use
of a connection module 14a.sub.5. As is shown in FIG. 5A, the
modular structure is shown in connection with a body R. FIG. 5B
shows a separate view of a modular structure 14a.sub.2, 14a.sub.3,
