- Equipment for fastening brackets

for benster parapet equipment -L ou f u n g The additional registration to P 29 50 312.6 relates to the accommodation of Lürtungseinrichtungen in the plate-shaped, made of insulating material Covers of window parapet walls and on a device for automatic Operation of these ventilation systems without the use of energy by using wind power.

For new buildings with energy-saving window constructions and for To renovate old buildings it has to be. proved necessary, systematically controllable Provide ventilation equipment and devices that allow fresh air to enter the sons.t. Let in hermetically sealed rooms and remove any stale air can be. In addition, ventilation equipment is provided.

with heat recovery, fresh air heating, air humidification and already desired with heat pumps.

Many of these devices are subject to additional requirements regarding the attenuation of external noise and intrinsic noises provided The above-mentioned necessities have to the constructions of ventilation devices and their installation in the area of the window, which, in addition to the high cost, have various disadvantages. The ventilation system is too conspicuous on the window front, the window area is reduced, special designs corresponding to the window width are required, there are significant manufacturing and assembly costs, the supplement and Converting the system is often not possible.

The housing is by far the most expensive part of such ventilation systems. It usually consists of a complex and surface-treated aluminum construction, which are separated into an outer and inner area for reasons of heat and sound insulation have to be.

In addition to being disproportionate for such a simple purpose large construction and subsequent maintenance costs, there is also a major disadvantage in the field the heat and switching insulation, in addition to the aforementioned division of the housing can only be remedied by complex built-in components.

The invention is therefore based on the object of a compared to the To specify structurally improved and simplified ventilation systems that are known, which is largely inconspicuous according to the purpose, the costs are not or only lightly loaded and if necessary commissioning and expansion to a self-chosen one Time in the then specifically required execution, as well as later adjustments by changing and expanding the ventilation equipment.

This task is carried out with a facility of the type mentioned at the beginning solved in that at least one of said heat insulating components for the ready-to-fit cover of the top .of window parapet walls a ventilation duct is incorporated parallel to the support surface, which in the position of use inner and Outside space connects.

The device mentioned also has various advantages. It is now possible to decide when to install ventilation units as well as - to leave the envisaged scope of the same to the client, since the housing set up in the window parapet is currently finished with a surface finish Molding is to be used, which is mainly used as a stiffening insert or as a Hilisregel element can be formed. When the molded part and the housing e.g. is wedge-shaped with a cross-section that widens in the spatial direction, so an air gap can be regulated by moving the shaped body. The shelter of Any ventilation device required - also seasonally - is then carried out after removal of the molded body by snapping into markings, the inner housing wall, or in previously inserted frames or sleeves. The boxes that are otherwise required are superfluous themselves.

Again, the object underlying the invention is durch.ein Essentially p "Iatten-shaped, 'heat-insulating finished construction element with ready-to-fit Surface solved, in which parallel to the support surface an inside and in the position of use Connecting the outside space and being more suitable as a housing for ventilation elements that are kept ready Channel is incorporated When using this, the other normal building blocks to be bricked up adapted, one-piece component made of heat-insulating and sound-insulating material is not required the extensive constructions and fixtures mentioned at the beginning.

These normal building blocks with housing must be good on the parapet wall anchored and their inside should be ready for expansion and thus for plaster and / or Be cladding panels stop.

The building element has a rectangular shape on thick breast walls enough hold. It is recommended for the most common thin parapet walls but for reasons of anchoring, the component has such an angular shape type, where its vertical leg rests on the inside of the parapet wall. whereby a good anchoring occurs. The overhang formed by the vertical leg expediently results in the ready-to-install upper interior area and stop at the same time for the plaster or panel cladding on the parapet wall below.

The vertical approach also makes it easier to use the Component for recesses and it is advisable to provide it uniformly.

These building ventilation elements can also have uniform lengths and dimensions hajen. .Length adjustments to the opening dimensions are made with fitting pieces of 1/2, 1/4, 1/8 stones, or are made from stones without recesses in a cutting box cut to length.

Advantageous further developments of the invention will. received when the foruit part forming the housing through lateral or horizontal channels with vore cavities or cavities seen in neighboring parts of the window breakout, preferably communicated in the insulation panels on the room side. The mentioned cavities or recesses can also be used up to the insertion of the devices with molded bodies must be filled in as above. The component forming the housing can also have vertical air ducts in the area of the reveals or window posts in connection stand, through which the warm stale air from below the ceiling into the Free can be directed.

These penster posts can be used as parts of the window construction Provide and train them in such a way that they can also function as independent ventilation systems can be used with and without their own fan.

In the case of floor-to-ceiling windows, the air coming from above is as close as possible led to the floor area. The used air is cooled down here outside and the fresh air warmed up inside.

For better air distribution and to avoid air currents horizontal suction and discharge ducts can be arranged above and below.

Without a fan, the performance of ventilation equipment can be significantly improved increase when congestion and suction of the wind act on the ventilation ducts.

This can be achieved in a simple manner in that to obtain the lamellas of the duct covers in the facade against the direction of air flow from dynamic pressure and placed in the direction of the air to obtain suction.

These required opposite positions of vertical slats are appropriately coupled.

Even with heat exchangers, it can largely be based on energy use be waived. At least this applies to the living area, where iw general only an air exchange to the extent that that of the previous leaking air is required window is equivalent to.

The ventilation possible without the use of energy must be used, it is a significant step towards saving energy.

In offices, it is sufficient to switch on the fan at certain times.

In addition to back pressure, suction and blower insert, it has vertical exchanger tubes also the cooling of the warm blankets air in.

'Ventilation pipes', which are mainly designed to exchange heat, create the movement of air the channels promoting influence.

The device according to the invention can advantageously be used in a thermally insulating Component for securing brackets for window sill fittings without cold bridges in accordance with patent application P 29 50 312.6 or utility model G 79 35 194.3 be.

Explanation of FIGS. 44-49 The advantageous interaction of ventilation elements on the parapet wall and heat-exchanging, stale air leading ventilation columns finally has to the explanations of the figures 44 - 49 led.

The ventilation elements of FIGS. 44 and 45 are about the height of a flat layer (stone height 71 mm) and are for the connection middle window ventilation columns provided in continuous window fronts.

The parapet ventilation elements of Figures 46 and 47 take part in the Ventilation columns adjoining the reveal and have ducts arranged one above the other in only one direction for supply and exhaust air and therefore the height of two flax notches, with an element length of predominantly 1 1/2 stones (365 mm).

These higher elements are on both sides of the window reveal in one Flat layer recess offset. Between these two ventilation elements will be on the subsequent flat layer it is advisable to provide those of normal height, that of the later occupant of the apartment for the subsequent arrangement of others, for example even the simplest ventilation equipment is available. When running after the existing ventilation wedge 2 'is sufficient for FIGS. 7-9.

Egg g; 44-47 are horizontal sections through ventilation entries as in Figures 26-28, but the supply and exhaust air ducts are in one blement Figures 44 and 45.

next to each other and 46 and 47 placed asymmetrically one above the other. In addition, these parapet elements have provisions for the connection of vertical ones Ventilation columns with and without heat recovery.

Fi 48 is section A-3 from FIG. 45 with the ventilation column inserted and big. 49 are the cuts C-D and E-F of Figures 46 and 47, also with inserted Ventilation column.

The embodiment shown in Figure 1 in a perspective view The invention shows a building element 1 made of heat-insulating material to be bricked up in the parapet crown and sound-absorbing material such as rigid foam, foam glass, wood concrete and the like with a cavity 2 and a lateral channel 3, which acts as a housing can be used for ventilation devices of various types. The openings of the cavity are here still closed by filling bodies 2 'made of insulating material. The interior of the Housing will be discussed later with reference to Figures 7-13. By using Such a component 1 eliminates the need for a wall breakthrough, among other things.

Such a lightweight component is retained - especially in the case of room-side protruding in the depth of the plaster or in the depth of thermally insulated plaster boards - a horizontal joint alone may not provide the necessary hold. It is therefore a perforated plate 1A stiffened by deformations or the like. vertically processed, the necessary in a mortar bed on the wall surface together with the bed joint Halt reached Fig.2 shows a component 1a of this type in an angled 'form, the hereinafter also referred to as insulation cap.

The downward leg can also be used as a housing part and connect to vertical insulation boards with a ready-to-use surface, as can be seen from Fig.4, the Dämmlcappe first at the exact height is offset and later with its lower edge of the vertical dama plate alb assembly aid serves.

The parapet wall can also consist of precast concrete parts according to Fig. 3, with a concrete frame 4 inserts made of insulation material 5 ', 5' ', clad ready for installation, 5 '' 'which can be removed individually or together to provide space for ventilation devices to release. In connection with the frame 4 there is a Damnsonicht 4a and one Outer skin 4b.

Fig. 4 shows a combination of an insulating cap 1a according to FIG. 2 with a vertical insulation board 1c. In both parts there can be recesses for ventilation devices be provided.

A wider version of a massive parapet wall precast than in Fig. 8 is shown in Fig.5. The insulation board 7 provided on the room side has a recess 2 on the left side for the later possible inclusion of one Ventilation device and is provisionally filled with packing elements according to Fig. 5a.

In the right larger recess of Fig.5, to which the packing 9, 9 ', 911 of FIG. 5b, there is space for a larger ventilation device, possibly with Fans and heat exchanger tubes that are vertical downwards extend.

The filling bodies 9, 9 ', 911 of FIG. 5b close the inner and outer openings until the devices are installed.

The filling body 9 ″ is additionally provided with a cover or a film covered against the ingress of moisture or insects.

The device according to FIG. 6, 6a, 6b, 6c differs from that Fig. 5 essentially in that the parapet wall with insulating caps 1a according to Eig.2 - is clad, of which the left a recess as in Fig.2, the right one has a larger cavity. Both have recesses in the side surfaces 10 provided, in which angular holders for attaching heavy parapet equipment inserted and possibly bricked up. These details are also in the patent application P 29 50 312.6 filed by the inventor.

Fig. 6 shows welter that insulation caps 1 a and insulation panels 7 in different Way as a housing can be designed as of ventilation devices. The whole The inner surface can be made ready for expansion by laying on building boards 11, see above that a smooth breeding wall, not interrupted by any elevations educated without using the recesses for ventilation purposes as a parapet wall ready for expansion serves.

Based on the following FIGS. 7, 8, 8a-c and FIG Expansion of the breeding wall with a building block of the top layer according to Fig. 1, as well the equipment with ventilation devices explained.

Fig. 7 shows the component 1 in cross section without vertical legs. As long as the component is not for its own or eventual purpose, namely is used as a housing for ventilation devices, the cavity with filler bodies is 2 ' Verse1 to stiffen and produce the thermal insulation, also with the insulation value corresponds to that of the subsequent modules.

The elements for connecting the ventilation opening are housed on the outside are required in the facade and in the correct by the plasterer or facade builder Position. These elements include the sleeve 13 for the Plaster crossing. An extension sleeve is required for a thick, heat-insulating outer skin 14 placed in between.

A sealing plug 12 is initially located in the sleeve.

This is when the recess is used for ventilation purposes from the interior exchanged for the facade grille 25 and air filter 15.

The wedge-shaped filling body 2 'can in the wedge-shaped opening of the Component already fulfill ventilation tasks when it is pulled out towards the room will. Depending on the depth of the extract, a more or less wide air gap. This means that a first expansion stage is free of charge of a retractable ventilation system.

A much more effective ventilation system is obtained if instead of the filling body 2 'a system according to FIG. 10 with a fan 16, plug-in contact 17, labyrinth 19 and blind 20, or according to FIGS. 11, 12 and 13 with one such double fan 16, two filters 15, or a sliding grille 2i (Fig. 13) is used will. These additions or additions are also made by the living space without any involvement made by a craftsman.

Big. 14 now shows the ventilation parts according to FIGS. 8a, 8b, 8c and Fig. 10 in an insulating cap according to FIG. 2 assembled ventilation device on a Window parapets in Fig. 15 are the parts according to Fig.11 and 13, in Fig.16 those of Figures 11 and 12 combined.

As already mentioned in the discussion of Figures 3 and 4, leave very powerful and energy-saving ventilation systems can also be inconspicuously integrated install the parapet wall, even if the structural elements lining the inner parapet wall as a precaution, with recesses and channels for each and, if necessary, with the associated packing have been provided. Examples of this are shown in FIGS. 17, 18 and 19 as well as supplementary Figures 20-21, 22, 23.

In Figures 17 and 18 there is a ventilation system with a heat exchanger device 23, which is used in both the upper and the inner insulation layer of the Window sill is embedded.

The heat exchanger device 23, consisting of two parallel ventilation ducts with close thermal contact for the fresh air drawn in and the used room air, has the advantage that the flow directions in both guides are parallel. Hierdurc; there are favorable conditions for exploitation the amount of heat contained in the room air flowing out.

This type of ventilation requires the two channels to cross in the upper part of the building, which are carried out in the manner shown in Figure 20 can. Another form of a heat exchanger can consist of two ventilation ducts - parallel exist to the parapet edge, as indicated in FIG. 19.

It will often be convenient that. Inlets for fresh air or room air or both as high as possible at a level below the ceiling to attach. The then for connection to the ventilation devices in the parapet wall The necessary channels are laid in the area of the reveal, either in Form of a double pipe in the reveal (Fig. 21), or at an angle between the reveal and the outside of the window frame (Fig. 22), or between the reveal and Benster frame (Fig. 23). Finally, the window mullions can also be used as double tubes be trained.

In the following figures, the upper section of the armor wall is made up Made of molded structural elements in a heat-insulating building with parallel to the parapet edge Extensive housings for accommodating sound-absorbing ventilation elements, The insulation effect can be determined by the dweller by the type and number of uses is. During quieter times of the day, there is free passage without insulation and fans can be produced in a simple manner by removing the inner closure.

FIGS. 24 and 25 show various cross sections through parapet walls Strength with a trained as an insulating cap.

deten, sound- and heat-insulating molded component, Fig. 24 with external building insulation made of plastered insulation structures and Fig. 25 with external plaster without insulation layer The insulation caps of Figures 24 and 25 consist of Insulating bodies of the same size, which have a fixed, possibly

massive cladding (V) of different widths around the to be able to compensate for different wall thicknesses without having to change the molded body.

24 shows a cross section through the fan 30 of the ventilation device, which is covered on the raunis side with a Verochluf3keil 31. outside is in the side An extended installation sleeve 32, offset from a distance, indicated by dashed lines.

A window sill bracket 36 is screwed onto the support bracket 34 which is attached to a low, bordered window sill 39. Once the plant pots are advantageously removed from the area of the discs and on the other hand, in this recess, the cooling on the window collects sunken stale ceiling air for transport outside.

In contrast to FIG. 24, FIG. 25 shows an insulating body which is unclad on the room side 40; the section is made through the support bracket 34 and in the plan of FIG marked with G-TI.

A removable frame is attached to the inserted support bracket -34 41 and below a window sill bracket 36 attached.

The removable frame-41 takes ventilation grilles, flaps, closed covers, jewelry plates and the like. Here is a record 45th arranged.

The sets can be lifted and swiveled out for cleaning purposes easy to remove, for this purpose the upper fold is deeper than the lower.

The cable tray 49 shown in FIG. 24 is here behind the support bracket continued as a recess. Those that may have remained for reasons of production thin walls on both sides of the support bracket are pierced if necessary. The protruding removable frame creates a second cable channel on the insulation cap 49 'formed.

The small section under Fig. 25 shows the same point from above, however, instead of the window sill bracket 36, a parapet profile 51 is arranged, its outer gutter radiator and window sill consoles, and its inner gutter Removable parapet wall cladding panels that can be removed for cleaning purposes and for replacement 53 wear. The parapet profile has a clamp fastening to save holes.

Figures 26 and 27 are A-B plan sections of Figures 24 and 27 25 in a greatly reduced size tub.

In FIG. 26 there is a supply air on the left and an exhaust air element I and on the right II arranged. In the outer wall of the duct there are floor and ceiling facing towards the floor of the channel stiffening connecting tongues 55, 57 formed. The counterpoints 56 are located on the locking elements (isometric drawing and section E-F on the right) and are with these for cleaning purposes or for reinforcement or

Reduction of the insulation effect can be exchanged and supplemented.

In Fig. 26, the wind is also used to increase the performance of the ventilation device used in two ways by standing upright through the facade frame arranged inclined louvre pressure and suction exerted on the ventilation ducts.

The airflow directed from left to right. 130 causes the left ventilation duct at the slat position 101 a pressure and right at the Position; 102 a suction. On the left the air is pressed in and on the right it is sucked out.

In both cases it will be the same despite the sound-absorbing labyrinths With a low air flow, the effect of a light fan is achieved. this is sufficient in an emergency as a replacement for the no longer existing leaky window.

If the wind changes, the devices work in the opposite direction, i.e. exhaust air on the left and supply air on the right. With this system, the slats can be fixed be arranged, therefore an "amplifier funnel" is also here in a simple way 103 can be added.

This energy-saving ventilation device can also be used as a Form heat exchangers. For this purpose, versions I and II - through a heat exchanger film separated - arranged one above the other.

The more effective version with a central air duct in a heat exchanger tube 36 can also be provided for the horizontal ventilation devices or similar.

The ventilation devices work in these horizontal ventilation systems in both directions, so also do not require any movable slats like this one for example, the vertical ventilation elements of FIG. 36 are required.

With the currentless operation of heat recovery elements a substantial energy saving is achieved.

The exchange of air in the spring, which was previously regarded as sufficient leaky windows should at least be reached here, probably surpassed.

In special cases and when there is no wind, the fan is switched on. Excessive ventilation with devices is unnecessary Power consumption. Even with heat exchanges, only part of the heat is recovered, probably the greater part is lost. Therefore, such facilities must be without energy consumption operate.

The transverse walls 59 shown in dashed lines are additional inserts. To A free ventilation passage can be created by removing the room-side cover will.

On the right exhaust air element in FIG. 26 there is a on the right reveal Ventilation duct 61 indicated, which is when the room-side air inlet opening is closed the used, warm Luit from the ceiling area.

The ventilation elements are always the same size. Dimensional differences are -with made of solid building material with heat-insulating fitting pieces of the same cross-section closed.

27 shows a three-part ventilation element I, II, III with an exhaust air inlet right exchangeable blower 30 in the middle and exhaust air outlet on the left, the at light wind through suction 102 does not need a fan Adjustment of the slats vozzanehaen.

The sound insulation is provided by alternately arranged above and below Tongues 63 (see longitudinal section Fig. 28). The room-side covers 65 of the ventilation duct are detachably locked in place for cleaning purposes or for retrofitting.

The same ventilation system should be installed in another window in the room be included as a supply air element. Both eluents can then change their function as in Fig. 26.

Fitting pieces are also used here to bridge length differences used.

Furthermore, FIG. 28 shows the view of the vertical section C-D of FIG. 27 with the tongues 63 on the top and bottom of the ventilation duct.

Fig. 29 is an interior view of a floor to ceiling window wall.

In the parapet fields of the windows 71 and 72 there are two dummies each with ventilation system in the embodiment according to FIG. 30 used, in the window 73 is this ventilation insulation cap is supplemented by a heat exchanger device according to Fig. 31, in window 74 there are two of these aforementioned elements and in window 75 there is a wide one Element used.

The ventilation systems always have the same dimensions.

Differences are closed with panel cuts.

When such fittings are placed next to vertical air feed pipes they are equipped with horizontal connection ducts.

The feeder tube is shown in left cross section C-D.

For reasons of illustration, the horizontal dimensions are five times drawn on a larger scale.

The arrow 81 indicates the entry of warm air under the ceiling at. The warm air is in the middle heat exchanger pipe 78 at 83 in the ventilation insulation cap gefübzt.

This heat exchanger pipe 78 is on the one side from the fresh air 84 which is preheated at 85 and enters the associated ventilation duct of the insulation cap.

The lower area of the feed pipe that is not required for the air supply 77 'can be filled with insulation material, for example. The condensation water is from collected in a collecting tray 79 and led into the open via a discharge pipe 79 '.

In the filling of the window 72 is a recess for an electrical Can element 47 is provided.

In the right cross section A-B, a feeder pipe 77 is shown which can be used as a stand-alone ventilation system. Step exhaust and fresh air as in section C-D above at 81 and 84, but are guided as far as Bussboden After this extended exchanger path, the exhaust air reaches the open air at 81 'and the Fresh air at 84 'into the room.

Horizontal air intake can be connected to the vertical air supply pipe. 87 and Luftausbaaskanäle 88 be connected, as in the window 75 in the View is indicated.

83 and 85 are provided access points for the connection of any ventilation elements in the window parapet.

Fig. 30 shows on a larger scale one in the windows 71 and 72 of the Fig. 29 ventilation device used in cross section. Here the exhaust air is at 81 81 'directly or via a soundproofing device into the open air and the fresh air that has been warmed up 84 led into the room at 84 '. The two air streams exit at 83 and 85 the vertical element into the horizontal element.

During the warm season, with the appropriate flap position the air exchange takes place directly without an exchanger, with or without a fan. Since without larger costs the entire length of the window - provided with ventilation precautionary devices different ventilation systems can be set up even in small rooms set up at the same time. In the case of window sills 39 'arranged at a low level, it is also possible It is easy to see from a distance whether a ventilation system is in operation and which one will. The binding display device can also provide information about the strength of the ventilation.

The horizontal air ducts of the insulation cap do not have any external ones here Insulation layer, because this is between the insulation board filling and the one with sealing strips provided window frame is not required. The horizontal insulation layer is located only to the side of the canals. The channel cross-sections can be regulated by flaps 89.

84 "is the direct fresh air access when the exchanger tube is not used.

In Fig. 31 to 1 i, a heat exchanger element is under the insulating cap la 23 connected in order to be able to extract further heat from the exhaust air. The condensation is collected in a vessel 90 or drained off via a drainage pipe 90 '.

83 and 85 are again the feeds from the vertical to the horizontal Ventilation element.

The window sill 39 is removably mounted on the parapet profile 51. This parapet profile 51 is on the holding profile 77 "des vertical feeder pipe 77 screwed at the desired height. Particularly beneficial is a low window sill arrangement 39 '.

The parapet profile 51; 51 'has a hanging groove for assembly of radiators and other parapet equipment.

The parapet profile 51 'is set up for clamp fastening.

This eliminates the need to drill holes on the construction site.

In .32 the plan section G-H of Fig. 29 is timed.

The feeder pipe 77 contains the heat exchanger pipe 78.

The feeder pipe 77 simultaneously stiffens the penster wall and gives you also have a three-dimensional structure.

The feeder pipe 77 has - if necessary on all sides - outer and inner retaining profiles, For example, C-profiles 77 '' on which window elements 91, parapet profiles 51, 51 ', Cover and retaining strips 92 (Fig. 33), ventilation grille 93 (Fig. 29), the heat exchanger pipe 78 etc. are adjustable.

Between feeder pipe 77 and window frame 91 is a sound and heat insulating cladding 94 arranged. The facade strip 95 covers the access and exhaust air openings in the vertical ventilation element, gives the facade a three-dimensional appearance Appearance and is a funnel-shaped air duct, which the dynamic pressure and suction the air in front of the canal mouths is reinforced. Fitting pieces 96 between the window sills 39 cover the horizontal leg of the parapet profile 51, 51 '.

Sig. 33 is the horizontal plan section I-K indicated in FIG through the parapet. Filling 97 is in the window. For better thermal insulation and accommodation of ventilation equipment is this around the insulation board that is ready to be removed 98 reinforced, which is held by the sound-absorbing cover and retaining strips 92, their attachment to the holding profiles 77 ″ of the vertical air feeder tubes 77 takes place.

The insulation filling of the lower one is in the left vertical feed pipe Area only hinted at. This insulation filling is not required if the vertical pipe is used alone is to be provided for ventilation and is used for this at the full height. To the existing upper air inlets 81 and 84 are the Air outlet openings for extending the exchange path are arranged as far down as possible. This heat-exchanging vertical pipe fan can be used in combination with sill fans, as well as being used alone.

The fan 30 consists of a middle and two side oaks running in the same direction Pneumatic wheels on a common axis.

The various ventilation inserts allow adjustments to any situation, especially because of their exchange and supplementation options.

In Fig.34 is. a predominantly made of impact-resistant plastic Ventilation housing built into the wall dust stone 1a designed as an insulating cap.

The housing has attached brackets for parapet equipment, on the left a perforated plate 105 and on the right a C2 profile 110. The top of the housing is shown open.

35 shows a reinforcement molded into the building material of the insulating cap 106, on which C-profiles 110-are set as the age for parapet equipment.

In the C-ProCilen 110 there are plastic strips 111, for example Made of nylon, in which, among other things, the screws are fastened that make up the removable frame 41 in Fig. 25 hold.

Fig. 36 is a section through a heat exchanging ventilation column. The section line G-H is entered in the plan of FIGS. 41-43.

The ventilation column is without energy with dynamic pressure and suction of the outside air operated. The fan 30 can, however, for use in calm or special Situations are provided.

Above and below are the two quickly possibly integrally pressed interchangeable mouthpieces with the vertically arranged and ventilation louvers in opposite directions, as shown in the floor plans the Figures 41 and 43 is shown.

The arrow 81 indicates the entry of warm air through the heat exchanger tube 78 at 81 'cooled to the outside.

The fresh air enters at 84 in the soundproof and heat-insulating upper t.iundstück and is guided downward in the outer feeder pipe 77, whereby it washes around the exchange tube 78 and enters the room warmed at 84 '.

79 is the sweat and rainwater collecting floor - both. Air currents 81 and 84 flow through the possibly provided fan 30 in fixed lengths provided middle part of the ventilation column. The fan 30 is, as already mentioned, operated only with little air movement or for special cases.

The ventilation column of Fig. 36 is the window mullions a, b or c. 39, extended by the parapet height, it would be one the door post d, e or f from the general sketch Fig. 40.

Fig. 41 is the plan section through the upper replaceable sound and thermally insulating prefabricated mouthpiece and FIG. 43 the plan section due to the similarly designed lower mouthpiece.

The vertically positioned lamellae in FIGS. 41 and 43 are opposed arranged and times ozen against and down in the direction of the air, this becomes up the fresh air is pressed into the ventilation duct and the exhaust air is sucked out of the duct below. The "work force air flow" is thus here twice in a ventilation device utilized.

If the wind direction changes, these will be used as possible for the setting coupled slats, as explained in the description.

Fig. 42 is the middle plan section C-D through the for special Blowers intended for situations 30.

It can also be seen here that the feeder pipe 77 is below other is made in two parts for reasons of heat and sound insulation and is made from outside a U-2 profile 77A made of possibly

additionally soundproofed PVC, polyurethane-lfart foam or similar Building material exists. In the C-profile 77A there is an inner one consisting predominantly of metal U-nrotiI 77 with holding profile holes 77 '' engaged.

91 are the adjoining window frames.

Fig. 37 shows the view of the ventilation column from the outside with the vertical arranged and facing in opposite directions air guide blades 104 before the upper air inlet opening and the lower air outlet opening.

Fig. 38 shows the view of the ventilation column from the inside with the adjustable Duct termination grilles 106.

Fig. 44 relates to a parapet wall ventilation element, in the opposite Fig. 26-28 The supply and exhaust air ducts are housed in the same element in such a way that that with every -Windricntung supply and exhaust air flow without switching operate. The air flow 100 is indicated once from the left and once from the right. The dynamic pressure 101 and the suction 102 act accordingly from the left and from the right. These functions are somewhat weakened if the air guiding attachment 110 is not in front is.

The inner cover 65 - on the far right - is on the front wall of the ventilation element pushed and thus achieved the elimination of the sound-absorbing labyrinth and direct ventilation.

After removing the filling pad 12G, a ventilation column can be inserted the parapet wall ventilation element as a supply of used-r 'cooled ceiling air and use warmed fresh air, as shown in Fig. 45. The ventilation column 121 is, as shown in section A-B of FIG. 48, designed at its lower end so that that the exhaust air exits at 122 outside and the supply air at 123 inside. In this version the flaps 124 and 124 'must be adjusted depending on the wind direction to a best To achieve ventilation result. The fan 30 can additionally provided and operated if necessary.

The parapet wall ventilation elements of Figures 46 and 47 are suitable also for the connection of ventilation columns, which are arranged on the reveal. For this, the parapet wall element is designed asymmetrically and the supply and exhaust air channels are on top of each other. Fig. 46 above shows the upper channel of the two-layer Element, the exhaust air coming from the ventilation column from the left when there is a draft of 100 - here with the support of the wind - leads to the open air.

There are various functional options here, for example is 49 shows the slide mouthpiece 121 of the heat exchanger tube 78 in section C-D of FIG locked in the upper position. The lower outlet is for the supply air flow 123 open.

The lower outer flap is closed. This channel would if used of the parapet wall ventilation element without ventilation column is required.

34 is again the recess for the hang-up holder, its horizontal Leg transfers the loads from above to the parapet wall. The upper recess for the support bracket 34 'is not required here and is filled with mortar.

Fig. 47 shows the same situation, but there is a draft from the right. For this purpose, the slider mouthpiece is iil according to the section E-F of Fig. 49 moved down. This enables the upper duct opening for the fresh supply air. The exhaust air escapes into the open in the lower duct.

When using without a ventilation column, the filler piece 125 is removed and the space for the ventilation column is closed with a filling cushion 120 as in FIG.

This parapet wall ventilation element gets a good hold in the recess in the breeding wall through the vertical mortar joints on the reveal and the flat layer.

The invention and its developments are particularly notable through the following advantages: 1. The invention solves the technical contradiction between the demand for an energy-saving and sound-insulating window wall, and those for an effective ventilation system by housing the system in thermally insulating construction elements in the window area; 2. At the same time, in particular with the parapet design, an expensive ventilation tu ngse tiäu jC saved; 3. At the same time, the architectural character of the window wall is retained, since boxes reducing the window area are not required; 4. For a change or expansion of the ventilation system can be used as a precaution in insulating construction elements Space closed with ready-to-use fillers kept ready until use will; 5. The new ventilation system with its various ventilation inserts is suitable is also suitable for office buildings and can be expensive in terms of acquisition and operation Replace central ventilation, which is no longer up-to-date for reasons of energy saving is; 6. Window mullions with replaceable ventilation devices direct used ones Ceiling air - heat transferring to the fresh air - outside; 7. The architect only takes precautionary measures for ventilation systems that the apartment user needs Purchases, supplements, replaces and when moving as furnishings yourself in due course takes away. The work of the architect for Ventilation measures are omitted, if it is included in the preliminary remark of the tender that for the final shift Ventilation precautionary elements -xyz- are to be used on window parapets; 8. Largely Energy-free operation of the ventilation systems through the use of wind power significant economic and domestic advantages; 9. The proposed simple, inexpensive and perfect solution facilitates the general introduction the ventilation system.

For living rooms, offices, schools, hospitals and the like.

it offers both unattended and adjustable. mostly Free room ventilation, possibly forced ventilation.

The construction costs are due to the precautionary measures for ventilation systems only lightly loaded.
