Description

Supply Arrangement

The invention relates to a supply air arrangement for a building. More specifically, it is a supply air arrangement for a building, which comprises a supply air window with a supply air valve that automatically adjusts to the supply air temperature.

In general, buildings have supply air arrangements where the supply air flows from the supply air valves located at the top of the window frames to the inside of the building. This arrangement of supply air valves in many cases complicates the window installation listings.

The solution of the invention eliminates the aforementioned drawbacks and provides an easy-to-install supply air arrangement. In the solution of the invention, a valve placed within the window frame makes the window easier to install. At the same time, it is possible to select the supply air route inside the building depending on the outdoor temperature, either directly from the outside through the upper frame or alternatively from the window space, whereby the solar thermal energy and the window heat loss are transferred to the supply air flow.

BRIEF DESCRIPTION OF THE DRAWINGS In the following, the invention will be explained in more detail with reference to the drawings, in which Figure 1 is a schematic drawing of a preferred embodiment Figure 3 is a schematic drawing of a preferred embodiment of a valve solution according to the invention.

Fig. 1 is a cross-sectional view of a preferred embodiment of the supply air arrangement according to the invention with winter ventilation. The window frame 1 is provided with an air duct 2 from the outside air to a space 5 between the windows 3 and 4. The air duct 2 is preferably provided with a filter that prevents air impurities from passing between the windows 3 and 4 and thereby reducing the need for window cleaning. The air channel 2 is preferably located in the lower part of the side frame 10 of the window frame 1 so that the cold outside air entering between the window panes 3 and 4 is warmed as much as possible before the air passes through the air channel 7 located in the upper window frame 6. Preferably, a grille 11 is located in the inlet of the air duct 2 to allow the air entering between the windows 3 and 4 to circulate as advantageously as possible between the windows. The air entering between the windows 3 and 4 is warmed by the energy of the sun and the heat transferred from the interior of the building due to the heat loss of the window. The upper window frame 6 of the inner window, the space 5 between the window panes 3 and 4, is preferably fitted with a valve 9 which is in the winter position in Figure 1 and then closes the channel 12 through the upper horizontal frame 8. The air entering the building and then through the air duct 7 into the building.

Figure 2 shows the structure of the valve 9 in more detail. Valve 9 is a butterfly valve, which in this example is in the winter position. In this case, the flap 14 of the valve 9 closes the air channel 12 through the horizontal frame 8 between the window panes 3 and 4, and keeps the route from the window pan space 5 into the building. In this example, valve 9 is implemented with two flaps 13 and 14, but the solution of the invention can be implemented using only one flap 14. Flap 13 is a non-return valve that prevents airflow back into space 5 between window panes 3 and 4, e.g. ylipainei-a). The flap 13 does not control the flow and descends when there is no flow (in the summer position) and opens when the air flow passes from the space 5 between the glasses 3 and 4 into the building.

Fig. 3 is a schematic drawing of a preferred embodiment of the supply air arrangement according to the invention with summer ventilation. In the summer, there is no need to heat the supply air anymore, whereby the valve 9 mounted in the upper inner window sash (s) 6 opens the air duct 12 through the horizontal frame 8 and the outside air is directly fed into the building through the top of the window. The air route through the upper horizontal frame 8 first passes through the perforation of the profile strip between the outer window frame 15 and the upper horizontal frame 16, for example, aluminum, through the perforation of the profile strip. From within the profile strip 16, the air flow is directed through the horizontal frame and through the flap 14 of the valve 9 directly through the inner window sash 6 into the building. During winter setting, the flap 13 of the valve 9 is closed when the air does not pass from the space 5 between the window panes 3 and 4 to the indoor air. Preferably, a filter is also provided in the air duct 12 to prevent impurities in the outdoor air from entering the space between the window panes 3 and 4 or inside the building (not shown in Figure 3).

Figure 4 shows a simple principle drawing of the valve 9 mounted in the upper frame between the window panes. The valve arrangement is preferably a simple butterfly valve, whereby adjusting the position of the valve flap 14 allows the air flow into the building to pass through the winter or summer route. Preferably, the control is not an on / off control, but the position of the flap 14 of the valve 9 can be infinitely adjusted to provide an adjusted air ratio between the winter / summer routes. In this way, the temperature of the incoming air is infinitely controlled. The flap 13 is a non-return flap which prevents the air from returning to the space 5 between the window panes 3 and 4, for example in a suitable wind or when the ventilation is malfunctioning (excess pressure). The flap 13 does not control the flow and settles down when there is no flow (in the summer position) and opens when the air flow passes from the space 5 between the glasses 3 and 4 into the building.

The automatic air flow control of the invention includes a thermostat section 20, a slide section 21, a rotatable spiral section 22 and a return spring 23. As the temperature rises, the piston of the thermostat section 20 pushes the slide section 21 which rotates the spiral section 22 like a slow worm gear. The spiral part 22 is connected directly to the shaft of the air guide or valve 14 of the valve 9, which controls the so-called air guide. summer position. As the temperature drops, the thrust of the piston of the thermostat section 20 decreases and the return spring 23 pushes the slider section 21 and the thermostat section piston to an initial position, whereby the air guide of the valve 9 is reintroduced. winter position. The flap 14 continuously adjusts the airflow between the summer and winter routes. The mechanical solution may also be another known technical solution in which the temperature 14 is controlled by the flap 14 and thus the flow between the different channels 2 and 12. It is essential to position the valve 9 in the inner window frame 6 between the glasses 3 and 4 to obtain a controlled winter / summer flow ratio. As stated previously, the butterfly valve 9 can be implemented with only one butterfly valve 14 without a non-return valve 13.

Preferably, the aforementioned air ducts 2, 12 and 7 are located in the window structures as described above. However, the scope of the invention does not limit their placement at other locations in the window structures. For example, air ducts 12 and 7 may be located in the vertical portions of the window structure instead of the upper horizontal portion.
