for extracting the flue gases of a heating device but also is used to ventilate a room. According to the present The invention is therefore the use of the I-shaped channel system suggested for ventilating the skin.

TJari I-shaped duct system is characterized by the feature that a compensation zone is created in the vertical channel so that the suction effect can be increased by in an ascending air flow is generated in the vertical duct. In this case, the rising airflow can be under the effect generated by fans placed in the duct and driven by a motor. Instead of this Method, the rising air flow can also be determined by the flow resistance and by the static pressure as a result of the characteristic Formation of the sewer system are caused. It goes without saying that in this case a wind is considered to be external factor should prevail »

nal 5 can be used for each floor in total, with a separate vertical channel 6 can be arranged in each room, which is connected to these two horizontal channels is·

The aforementioned channel system is given a shape like TTT _{ζ β} Β · in the case of three vertical channels corresponding to three rooms on one floor.

The above-described design of the channel system enables a minimum of the cross-sectional area which the channel system 3 claimed in the building »Since the distance between the outlet openings B-B 'of the upper horizontal channel 5 and the Inlet openings A-A 'of the lower horizontal channel 4 is several meters, the one on the upper and the lower channel the wind pressure acting on it is roughly the same, whereby the state of equilibrium in the vertical channel 6 can be improved

The possibility of arranging a plurality of vertical channels 6 also has the advantage that the location of the heating device 7 is freely selectable

The embodiment illustrated in FIGS. 3a-3d has the 'purpose in the vertical channel 6 of the I-shaped channel system 3 to generate an ascending air flow when there was a wind flow

In order to make the resistance to the air flowing into the lower horizontal duct 4 greater than in the upper horizontal one Channel 5 is designed to be smaller in the embodiment of FIG. 3a, the cross section of the lower horizontal channel 4 as that of the upper horizontal channel 5 «If a wind pressure is exerted in the direction of the arrow drawn, therefore, the air flow speed (wind speed) in the upper horizontal duct 5 becomes greater than that in FIG

the lower horizontal channel 4 o The air in'dem vertical channel 6 is therefore _{sucked in or o} into the upper horizontal channel 5, in which there is a high flow rate, so that a continuous rising air flow can be generated in the vertical channel 6 as long as a There is a wind current ο

In the embodiment illustrated in FIG. 3b, the flow resistance in the upper horizontal channel 5 and in the lower horizontal channel 4 is the same; Area a static pressure chamber 9 is arranged. During a wind flow, therefore, the static pressure in the static pressure chamber 9 is higher than the pressure at the confluence of the vertical channel 6 in the upper horizontal channel 5, so that the air contained in the vertical channel 6 is pressed into the upper horizontal channel, whereby during a wind flow a continuous ascending air flow is generated _o

In the embodiment illustrated in FIG. 3c the flow resistance in the upper horizontal channel 5 of the channel system is just as great as in the lower horizontal one Channel 4, the area of the upper horizontal channel 5 in which the vertical channel 6 opens into it tapers and is designed as an acceleration area 10. The flow velocity of the air is therefore in the acceleration area 10 larger than in the area in which the vertical channel 6 opens into the lower horizontal channel 5, whereby the air contained in the vertical channel 6 is sucked into the acceleration area 10, so that in the vertical Channel 6 v / during a wind flow a continuous ascending air flow is generated o

In the embodiment according to Figo 3d, the flow is

resistance in the upper horizontal channel 5 and in the lower horizontal channel 4 of the channel systema the same, the area of the upper horizontal channel 5 in which the vertical channel 6 opens into this, is tapered to form an acceleration area 10, and that area of the lower horizontal channel 4, in which the vertical channel 6 opens into this, is expanded by a static one To form pressure chamber 9. The static pressure in the acceleration region 10 therefore becomes lower than that in the static pressure chamber 9 »so that an ascending air flow is continuously generated in the vertical channel 6 when there is a wind flow,

The use of the embodiments described above causes an ascending air flow in the vertical duct 6, when there is a current of wind 'Instead of these hatreds for Generating an ascending flow of air can also be done in the vertical Channel 6, in the upper horizontal channel 5 or in the lower horizontal channel 4 motor-driven blowers to be ordered.

In the embodiment shown in Fig. 4, the I-shaped duct system is used to ventilate the room »

When the rooms are closed, air is supplied to each individual room by means of a ventilation system, the cross-section of the air supply and / or discharge channels increasing according to the number of rooms. In such a closed space, a heater that emits the combustion gases into the room cannot be used, as this would cause air poisoning ₀

This problem can be solved by creating a channel to ventilate each room.

The ventilation of the closed space is subsequently

hand of the embodiment _{shown in EIg 0} 4 explained ₀ In the ceiling of the room Π the upper horizontal channel 5 passing through the building is arranged, and under the floor of the seam R the lower horizontal channel 4 is in the same view as the upper horizontal channel channel positioned 5, wherein the upper horizontal channel 5 is connected to 'the space R via an exit tube TT and the lower horizontal channel 4 is connected to the space R through an inlet tube 12 ₀ the space R thus corresponds to a certain extent the vertical channel 6 _O

'Through the construction described above, in the room R created a compensation zone, and if for any reason a draft is created in the room R, the air will escape Space through the outlet pipe 11 and the upper horizontal channel 5 into the atmosphere and fresh air flows through the lower horizontal channel 4 and the inlet pipe 12 in the Room R a «. Since the ventilation of the room is based on that previously described An actual ventilation device and the shared air supply duct is effectively carried out superfluous, and the heater with open combustion can-be used in the room R «.

If the ventilation of the room is carried out in the manner shown in Fig. 5, the horizontal duct 5 is arranged in the ceiling of the room R and the inlet openings AA 'are in the lower region of the room R in the same direction as the outlet openings BB ^{1 of} the upper horizontal channel 5 and it can be assumed that they achieve the same effect as was explained in connection with Figo 4 «

To ventilate the room, the motor-driven fans can be installed in the upper horizontal duct 5 or in the outlet pipe 11 to further increase the ventilation of the room by operating these fans
