- both the gravitational system and the exhaust air ventilation system apply a replacement air valve, via which replacement air is introduced into the room.
- a replacement air valve is typically provided in connection with a window, for example in the built-in frame above the window or in the casement frame.
- the window comprises three panes
- the window thus comprises two interspaces, of which the first one is between the outermost pane (the pane on the outdoor side) and the middle pane, and the second one is between the middle pane and the innermost pane (the pane on the indoor side), respectively.

- the replacement air flows downwards; in other words, it, in a way, runs on the inner surface of the first pane 9a. From the room, warm air is emitted and conducted through the panes into the interspace, wherein replacement air from outdoors also becomes slightly warmer when it flows downwards. At least partly for this reason, the air flow starts to turn upwards towards the upper end of the first interspace 10a.

Abstract
Description
- The present invention relates to an air guide according to the appended
claim 1 as well as a window according to the appendedclaim 4. - For implementing the ventilation of rooms, gravitational ventilation systems, exhaust air ventilation systems, as well as supply air/exhaust air ventilation systems are known. In the gravitational ventilation system, the ventilation of rooms is based on pressure differences and temperature differences, wherein warm indoor air tends to rise upwards and exits the room via an exhaust valve. This will result in an underpressure, by means of which replacement air is sucked from the outside of the room, typically from atmospheric air, via a replacement air valve into the room. The exhaust air ventilation system comprises a mechanical vent device which removes air mechanically from a room and causes an underpressure in the room. Thus, the underpressure causes a flow of replacement air via the replacement air valve into the room. The supply air/exhaust air system also comprises a mechanical vent arrangement for removing spent air from a room, and an inlet air duct system, through which replacement air is introduced into the room.
- Of the above-mentioned ventilation systems, both the gravitational system and the exhaust air ventilation system apply a replacement air valve, via which replacement air is introduced into the room. Such a replacement air valve is typically provided in connection with a window, for example in the built-in frame above the window or in the casement frame.
- With more stringent energy-saving standards, so-called supply air windows have been developed for the purpose of warming the replacement air before it is introduced into a room in a situation in which the temperature of outdoor air is lower than the indoor temperature. The supply air window utilizes thermal energy conducted from the room through the window, as well as thermal energy emitted through the window. Thus, this thermal energy warms the replacement air before it is introduced into the room. This is typically achieved with a replacement air valve comprising a duct system to guide replacement air into a so-called interspace in the window. A window normally comprises two or more panes, wherein said interspace is formed in the space left between two panes in the window. If the window comprises three panes, the window thus comprises two interspaces, of which the first one is between the outermost pane (the pane on the outdoor side) and the middle pane, and the second one is between the middle pane and the innermost pane (the pane on the indoor side), respectively. In such a case, the replacement air can be introduced into either the first interspace or the second interspace or even both, for example first into the first interspace and from there into the second interspace.
- In supply air windows of the above-described kind, two inlets are needed, of which the first inlet conveys the replacement air from the outside into the interspace of the window, and the second inlet conveys the air warmed in the interspace of the window further via the replacement air valve into the room. The first inlet is normally provided either in the casement or, for example, in the lower profile of the built-in frame of the window. Providing such an inlet requires drilling, milling and/or other work stages, so that an air flow duct is formed from outdoor air into the window interspace.
- It is an aim of the present invention to provide an air guide arrangement, in which the first inlet does not need to be manufactured separately, but it is implemented by utilizing an air gap formed in the window during its manufacture. To put it more precisely, the air guide according to the present invention is primarily characterized in what will be presented in the characterizing part of the appended
claim 1. The window according to the present invention is primarily characterized in what will be presented in the characterizing part of the appendedclaim 4. - The present invention shows remarkable advantages over solutions of prior art. When the air guide according to the invention is applied, there is no need to provide the window with a separate inlet for introducing replacement air from the outside into the window interspace, but this can be implemented by means of a gap left between the casement and the built-in frame of the window. Thus, the air guide and this gap together form a first inlet for introducing replacement air from outdoors to the window interspace in such a way that the replacement air from outdoors tends to flow downwards in the window interspace, until the replacement air becomes warmer and starts to flow upwards in the window interspace towards a second inlet, from which the replacement air is conveyed to the duct system of a replacement air valve and further into a room. By means of the invention, the supply of replacement air can be implemented by fewer work stages than by using solutions of prior art.
- In the following, the present invention will be described in more detail with reference to the appended drawings, in which

- shows an air guide according to another advantageous embodi- ment of the invention in a reduced cross-sectional view.
- In the following, we shall discuss the
air guide 1 ofFig. 1 in more detail with reference toFigs. 1 and2 . Theair guide 1 comprises afirst wall 2 which is used for fastening the air guide in connection with a window 3 (Fig. 3 ) in a way to be presented below. Theair guide 1 further comprises asecond wall 4 and aflow louver 5 which form afirst inlet 6 for introducing air into awindow interspace 10a, 10b. Theflow louver 5 is formed, for example, by punching or providing openings in another way in that part of theair guide 1 which is between thefirst wall 2 and thesecond wall 4. The openings can be made in the sheet preform 21, for example, by die cutting. An example of such a sheet preform 21 and the manufacture of an air guide from thesheet preform 21 will be described below in this description. - The
air guide 1 further comprises aguide wall 8 for the air flow, tending to guide the air flowing through theflow louver 5 towards the surface of the outer pane 9a of the window and further downwards in the window interspace. This will be described in more detail below in this description. It should be mentioned that theguide wall 8 for the air flow can be formed as a solid wall with saidsecond wall 4. If necessary, theflow louver 5 can be provided with one ormore filters 24 for filtering out impurities, such as dust particles etc., possibly entrained in the replacement air. In this way, at least part of the impurities are trapped in the filter and do not find their way into the room. -
Figure 3 shows an embodiment of a window 3 provided with anair guide 1 according to the invention. In this advantageous example, the window 3 comprises three panes 9a, 9b, 9c, wherein afirst interspace 10a is formed between the first pane 9a and the second pane 9b, and a second interspace 10b is formed between the second pane 9b and the third pane 9c, respectively. The window 3 also comprises afirst casement 11a and a second casement 11b, but it is obvious that the number ofcasements 11a, 11b may also be only one or greater than two. Thecasements 11a, 11b are preferably formed to encircle the panes 9a, 9b, 9c at each edge; in other words, thecasements 11a, 11b preferably comprise four casement elements, one at each edge of the pane. Each pane 9a, 9b, 9c is partly embedded in therespective casement 11a, 11b and, if necessary, the joint between thecasement 11a, 11b and the pane can be sealed with, for example, silicone. - Finally, the window 3 comprises a built-in
frame 12, to which thecasements 11 a, 11 b can be attached, for example, by hinges (not shown). The built-inframe 12 is also arranged to encircle the casements of the window, wherein the frame preferably consists of four frame elements. - The window 3 can be fixed to the
wall 13 of a room by any suitable fastening means (not shown). Between theframe 12 and thewall 13, a small gap is typically left, whose size is in the order of a few millimetres. This gap, such as, for example, the gap formed between the frame element above the window and thewall 13, can be used to accommodate, for example, areplacement air valve 14 to introduce replacement air into the room. - From the cross-sectional view of
Fig. 3 , it can be seen that there is asmall gap 15 between thefirst casement 11 a and the built-inframe 12 of the window, connected to outdoor air. At the stage of manufacturing the window, this gap may have been equipped with a sealing to prevent an air flow through this gap. In the present invention, thisgap 15 is utilized by fastening anair guide 1 preferably to thefirst casement 11 a of the window in such a way that theair guide 1 is in thefirst interspace 10a and that thefirst inlet 6 of theair guide 1 is in a flow connection with thisgap 15. Thus, replacement air from the outside can flow through thegap 15 and thefirst inlet 6 into thefirst interspace 10a. The airflow guide wall 8 of the air guide guides the flow of replacement air towards the inner surface of the outermost pane 9a of thefirst interspace 10a. This flow is illustrated by arrow F1 inFig. 3 . In a situation, in which the replacement air is colder than the indoor temperature, the replacement air flows downwards; in other words, it, in a way, runs on the inner surface of the first pane 9a. From the room, warm air is emitted and conducted through the panes into the interspace, wherein replacement air from outdoors also becomes slightly warmer when it flows downwards. At least partly for this reason, the air flow starts to turn upwards towards the upper end of thefirst interspace 10a. At the upper edge of the window, an air flow duct 16 is provided in the built-in frame to let the replacement air that has become warmer in thefirst interspace 10a flow into thereplacement air valve 14. This flow is illustrated by an arrow F2 inFig. 3 . - The upper edge of the
second wall 4 of theair guide 1 can further be provided with a sealing 20 to prevent the flow of replacement air from between thesecond wall 4 and the built-inframe 12 directly into the air flow duct 16. Such a by-pass flow might diminish the effect of warming the replacement air. - Preferably, the
replacement air valve 14 has two positions which may be called, for example, the summer position and the winter position. In the summer position, the above-mentioned air flow duct 16 is closed, preventing the flow of replacement air through the window interspace into the replacement air valve. This is advantageous, among other things, for the reason that in a situation in which outdoor air is warmer than the target temperature of indoor air, the warming effect of the window interspace is not desirable. In the summer position, the replacement air is guided to pass directly from theinlet 17 to the duct system of the replacement air valve and further into the room. - The window 3 can also be provided with a
protective plate 18 which, particularly above the window, reduces the entry of rain water through thegap 15 between thefirst casement 11 a, that is, the casement of the outermost pane, and the built-in frame into theinterspace 10a. A small clearance is left between this protective plate and thefirst casement 11 a along at least part of the length of thefirst casement 11 a, to enable the flow of replacement air into thefirst interspace 10a. - In the advantageous embodiment of the window shown in
Fig. 3 , thisprotective plate 18 also extends to the built-in frame advantageously so that anair gap 19 is also left between theprotective plate 18 and the built-inframe 12, allowing replacement air to flow into theinlet 17 of thereplacement air valve 14, when thereplacement air valve 14 is in the summer position. This flow is illustrated by an arrow F3 inFig. 3 . -
Figure 4 shows an advantageous example of asheet preform 21, of which theair guide 1 according to the invention can be made. Thesheet preform 21 is shaped so that by bending it at the locations marked with broken lines, the desired shape of theair guide 1 can be achieved. In the sheet preform ofFig. 4 , foursuch bending lines 22a-22d are shown. The area between thefirst bending line 22a and thesecond bending line 22b is provided with a set of openings, wherein this part of the sheet preform constitutes theflow louver 5 of theair guide 1. Thesheet preform 21 can also be bent at thethird bending line 22c to form the airflow guide wall 8. This airflow guide wall 8 can be provided with yet another deflection at the location indicated by thefourth bending line 22d. However, a relatively small deflection is made in this location, to prevent the flow resistance from growing excessively high. On the other hand, the deflection serves the function of directing the replacement air flow diagonally towards the surface of the first pane 9a to make the flow as close to this surface as possible and to enable the flow of replacement air down to the lower part of thefirst window interspace 10a before the flow turns towards the air flow duct 16 in the upper part of thefirst interspace 10a. It should still be mentioned in this context that theair guide 1 can also be made of two or more parts, for example in such a way that the airflow guide wall 8 is a separate sheet that is attached to thesecond wall 2 by means of a suitable fastening method. In this alternative (Fig. 5 ), the sheet preform can be thought to be cut at the third bending line into two separate parts, wherein one part forms thefirst wall 2, thesecond wall 4 and theflow louver 5, and the other part forms the airflow guide wall 8. - The bending angle between the
first bending line 22a and thesecond bending line 22b is in the order of 90 degrees, but in an advantageous embodiment, at least one of these bending angles is a few degrees greater than 90 degrees, wherein the distance between thefirst wall 2 and thesecond wall 4 reduces slightly when moving away from the flow louver. This makes it possible that thefilter 24 does not necessarily need to be fastened to theair guide 1, but it is supported by thefirst wall 2 and thesecond wall 4, between them. - The
air guide 1 according to the invention can be fastened to thefirst casement 11 a of the window by means of, for example, double sided tape,magnetic tape 23 that is, for example, glued to thefirst wall 2 of the air guide as shown inFig. 2 , sticker tape, or the like. - The
first interspace 10a and the second interspace 10b of the window 3 can be arranged in a flow connection with each other advantageously in the vicinity of the lower edge of the window, wherein the replacement air flowing into thefirst interspace 10a can move into the second interspace 10b of the window. Thus, the air flow duct 16 of thereplacement air valve 14 is placed advantageously in the second built-in frame. Thus, the replacement air entering the lower part of the second interspace 10b can flow upwards in this second interspace 10b and further through the air flow duct 16 into thereplacement air valve 14. - Even if the invention was described above in connection with a window, the
air guide 1 according to the invention can also be used, for example, in connection with a door arrangement for a balcony or a terrace. Such a door arrangement preferably comprises two doors, wherein a relatively tight interspace is left between these two doors (not shown) when both of the doors are closed. Theair guide 1 according to the invention is fastened at the upper edge of the outermost door, where at least part of the sealing is removed, if necessary, to enable the flow of replacement air from outdoor air via the air guide into the interspace between the doors. A replacement air valve can be provided at the upper edge of the inner door or in its upper built-in frame, through which valve the replacement air that has entered the interspace can be led into the room. - It is obvious that the present invention is not limited solely to the above-presented embodiments but it can be modified within the scope of the appended claims.
