Description

The invention relates to a ventilation system, in particular a quick installation ventilation system.

The starting point of the invention are energy requirements, in particular for existing but also for newly constructed buildings. In practice, the following problems have emerged in the energetic observation of buildings.

On the one hand is in the energy saving regulation and the German industrial standard DIN 4108-2 For energy reasons, the tightness of the building required. Not only in the new building, but also in the existing building stock, the required transmission heat loss can be maintained only with a given tightness.

On the other hand, according to the German industrial standard DIN 1946 , Part 6 requires a minimum change of air to protect the building substance, in particular from moisture damage and to ensure the indoor air quality for the residents. The necessary minimum air change is not given due to the required high density of the building and can not be provided manually by the residents.

Ventilation systems for controlled ventilation of living spaces are currently being installed in new buildings, as they are required for reasons explained, taking into account the Energy Saving Ordinance and the necessary minimum air exchange for building physics and energy reasons.

As a rule, central ventilation systems are used, which supply the individual rooms of the buildings via air ducts. Central ventilation systems with heat recovery facilities are particularly efficient.

The problem is the overcoming of the above problem, especially in an existing housing stock, which is rehabilitated to comply with the Energy Saving Ordinance in a facade renovation with insulation materials. In such a measure, the rooms of the buildings are not adequately supplied with fresh air unless they are simultaneously provided with ventilation of the buildings, i. if the necessary minimum air exchange rate is not provided in any way.

There are currently no viable ventilation systems that meet the requirements of the renovation of residential buildings, especially in multi-storey housing.

From the prior art, the publication DE 10 2007 025 469 A1 known. The document discloses an element for thermal insulation of a building. The attachment of the element to the building can be done later. It was recognized that it makes sense in the course of the thermal renovation of a building, not only to improve the insulation of the walls, but also provide a regulated ventilation. Proposed is a plate-shaped element for thermal insulation of a building, which is intended to be applied to an outer wall of a building, wherein the element has channels that can serve as ventilation channels. However, the cited document does not provide a workable solution on how the wall duct between the rooms to be loaded and the elements provided on the outer wall of the building should be equipped.

A second similar system described in the prior art is taken from the document DE 102 04 727 A1 out. There, a ventilation facade is described in front of a shell facade elements described with room-side vertical and horizontal chambers for air flow. Fans, heat exchangers, air flow regulators and filter elements are listed as possible integrated components in the ventilation system described there. The actual wall passage is also not described in detail.

In addition to this is from the publication DE 98 00 146 U1 a ventilation device for building openings known, which has a base frame and a flap pivotally mounted thereon with lamellae. Such a ventilation device can be placed directly in the facade of a building. However, such a ventilation device does not meet the requirements in terms of fire protection and sound insulation, so that it is not sufficient in compliance with safety regulations to integrate such a ventilation device in the known ventilation systems.

The publication DE 197 23 485 A1 discloses a device for ventilation of rooms, which comprises an air duct with at least one air inlet opening, which connects an outdoor area with fresh air through a wall with a room interior. This device already takes account of noise control and fire protection concerns, however, the device is also designed for "on-wall mounting". So that outer facades are more or less impaired.

Based on this cited prior art, it is the object of the invention to provide a ventilation system, which the ventilation of Rooms in buildings, especially taking into account the requirements for the renovation of existing housing allows, taking into account the needs of fire protection and sound insulation. Furthermore, the installation / installation of the ventilation system should be easy and safe to carry out.

The advantages achieved thereby are explained in more detail in the description.

In a further preferred embodiment, the lead-through element is characterized in that the lead-in element designed as a non-assembled hollow body comprises a modular plug-in grid element and / or a modular plug-in fat filter.

In a development of the stated embodiment, the grease filter is arranged integrated in the grid element of the feedthrough element, so that the grease filter can be plugged together with the grid element into the prefabricatable hollow body of the feedthrough element.

The hollow body of the lead-through element has, in a preferred embodiment of the invention, a first end against which a plug-in mounting socket, which can be plugged into the prefabricatable hollow body, serves to position the grid element and / or grease filter which can be plugged into the mounting socket.

In a further preferred embodiment, a discharge or supply air element can be assembled in the lead-through element, wherein a connection element is arranged in the hollow body for assembly with the waste or supply air element, which corresponds to a holding element provided in the hollow body near the first end of the hollow body that the Aboder supply air element at the first end of the hollow body can be assembled on the holding element.

Finally, it is preferably provided that the holding element of the exhaust or supply air element is arranged integrated in the assemblable mounting stub.

In addition, the invention provides that the hollow body of the lead-through element for assembling a further component, in particular a silencer of the ventilation system at a second end has a connection piece.

The ventilation system is thus characterized by a feedthrough element, in particular a wall feedthrough element according to at least one of claims 1 to 8. Wherein the ventilation system according to the invention comprises in particular a connected to the at least one feedthrough element silencer.

The feedthrough element and the silencer are parts of an exhaust air ventilation system and / or parts of a supply air ventilation system of the ventilation system.

The ventilation system according to the invention is characterized in a first embodiment in that the warm air for heat recovery in the exhaust air ventilation system is guided via a heat exchanger which is connected to the supply air ventilation system of the ventilation system.

In another embodiment, the ventilation system, in particular for heat recovery, characterized in that the warm air for heat recovery in the exhaust air ventilation system is passed through a heat pump of a heat pump system, which is connected to a heating system or a hot water system.

Finally, a further embodiment is proposed, which consists in that the warm exhaust air is guided in the exhaust air ventilation system for heat recovery via a heat pump of a heat pump system having a buffer memory, which is connected to a heating system and / or a solar system with a solar collector.

1 shows a first ventilation system L1 on or in a building G. The ventilation system L1 can be designed as a supply and / or supply air ventilation system. Pure waste and / or supply air ventilation systems are currently being replaced by waste and / or supply air ventilation systems with heat recovery.

The 1 shows the ventilation system L1 in the first embodiment, in which the outside air is drawn centrally from an outside air intake ventilation system L _outside and is passed through a heat exchanger LW, in particular via a cross-heat exchanger. Warm exhaust air from an exhaust air ventilation system L _{Ab is also} led to the cross heat exchanger LW via the cross heat exchanger LW. The warm exhaust air is sucked off especially in strongly odorous and above all in humidity-loaded rooms, like bath, WC and kitchen.

The extraction of the warm exhaust air from said spaces via at least one special or several special feedthrough elements 100 _From , which is installed in the wall G1 of the building G or retrofitted.

The most of several implementation elements 100 _Ab in a wall G1 summarized warm exhaust air of the building G in the cross heat exchanger LW to used, the preheat over the outside air Ansauglüftungssystem L _outdoor fresh air sucked in, after which the thus preheated fresh air as supply air through a supply air ventilation system L _to the rooms of the building G , especially in living and sleeping areas. The movement of the supply air into the rooms of the building G takes place via at least one special or several special lead-through elements 100 _To in the supply air ventilation system L _Zu .

The supply air can be filtered by appropriate aggregate technology within the ventilation system via filter elements or even dried if necessary via a dryer unit.

Up to 92% of the heat can thus be released to the intake outside air and thus to the heated supply air and be returned as warm air in the rooms of the building G.

By means of the first ventilation system L1 arises within the rooms of the building G from which the exhaust air is sucked through the exhaust air ventilation system L _Ab a slight constant negative pressure, which is adjustable according to the operation of the first ventilation system L1, so that the amount of exhaust air and the supply air is controllable. Within the first ventilation system L1 is ensured that the amount of exhaust air, the feed air L L is held _to device technology in _balance, and. It thus arises in an advantageous manner, a controlled exchange of warm exhaust air with heated and optionally conditioned (filtering and drying) supply air, within the building G overflow areas such. As doors or corridors, are formed so that the warm supply air controlled from the Zuluftbereichen of the building G flows into the exhaust air areas of the building G. The first ventilation system L1 comprises an exhaust air ventilation system L _Fort , so that a part of the unused volume flow of the outside air from the ventilation system L1 can flow regulated differential pressure as exhaust air.

The ventilation system L1 in the first embodiment has the advantage that it can be used for heat recovery. In addition, the first ventilation system L1 comprises at least one already mentioned special feedthrough element or several special feedthrough elements 100 _Off , 100 _To , which are located within the exhaust air ventilation system L _Ab or the supply air ventilation system L _Zu . On the implementing elements 100 _Off , 100 _To be discussed in more detail below, so that the benefits of using the feedthrough elements 100 _Off , 100 _To be clear in the following.

The first air system L1 further allows advantageously within the spaces of the building G, the simultaneous operation of air-dependent fireplaces in coordination with a chimney sweep. In addition, it is advantageous that the illustrated central air supply of fresh air via the outside air intake ventilation system L _{outside is} possible, so that the air supply is independent of external influences, so that the first ventilation system L1 can be operated in any weather condition. Within the first ventilation system L1, noise emissions are advantageously avoided, as will also be explained. In addition, the fire safety regulations are complied with, as will also be explained.

The 2 shows a second ventilation system L2 in another embodiment, in which the outside air is not centrally from an outside air intake ventilation system L _outside , but decentralized over in the wall G1 arranged wall or window valves 200 _{To get} into the rooms of the building G as fresh air.

Inside the wall or window valves 200 _{In most} cases, the fresh air is filtered, whereby in particular living and sleeping areas, ie living spaces and bedrooms, are supplied with fresh outside air.

As 2 illustrates, are in a building G usually several such wall or window valves 200 _To arranged.

However, as with the first ventilation system L1, heat recovery also occurs in this second embodiment.

Analogous to the first embodiment, spent warm exhaust air is discharged via an exhaust ventilation system L _Ab from the building G, the exhaust air ventilation system L _Ab via a heat pump system WPS with an exhaust air heat pump WP as exhaust air via an exhaust air ventilation system L _Fort in the open according to is directed outside.

The heat of the exhaust air is fed by means of the exhaust air heat pump WP in a heating system HS, which preferably comprises a buffer memory PSP. The thus recovered heat is z. B. used to support the heating system and / or to heat drinking water. It is understood that thus advantageously a lower consumption of primary energy within the heating system HS is the result.

It is also optionally provided to couple to the buffer memory PSP a solar system S, as 2 shows a solar line system S2, which establishes the connection between the buffer PSP and a solar collector S1, which is preferably arranged on the roof of the building G.

The extraction of the warm exhaust air from said spaces is also carried out in the second embodiment via at least one special or several special feedthrough elements 100 _From which is / is installed in the wall G1 of the building G or be retrofitted. In this second ventilation system L2 is formed within the spaces of the building G from which the exhaust air is sucked through the exhaust ventilation system L _Ab a slight constant negative pressure, which is adjustable analogously to the operation of the first ventilation system L1, so that the amount of exhaust air and the Zuluft is controllable. It thus arises in an advantageous manner, a controlled exchange of warm exhaust air with heated and optionally conditioned (filtering and drying) supply air, within the building G overflow areas such. As doors or corridors, are formed so that the warm supply air controlled from the Zuluftbereichen the building G in the exhaust air areas of the building G. flows. The ventilation system L2 is also completed by an exhaust air ventilation system L _Fort , so that a portion of the unused volume flow of outside air from the second ventilation system L2 differential pressure regulated as exhaust air can flow, so that used air can be discharged as exhaust air.

An advantage of the second ventilation system L2 is that the heat recovery is even more efficient than the first ventilation system L1, since the second ventilation system L2 compared to systems with cross-heat exchangers L1, the recovered energy from the exhaust air in a buffer memory PSP (layer buffer memory) Heating system HS can be stored in different temperature levels for hot water and / or to heat the building G.

Even without solar system S, for example, the entire hot water demand of the building G can be covered. Such a second ventilation system L2 can be retrofitted just like the first ventilation system L1. In the second ventilation system L2, the existing heating system HS is advantageously coupled to the retrofitted second ventilation system L2. It is understood that a new building in the manner described can be equipped. The retrofitting or the new construction of the two described ventilation systems L1, L2 is associated with low cost and feasible installed or retrofitted, as will be explained below.

The second ventilation system L2 coupled with an exhaust air heat pump system WPS and a solar system S are characterized by high efficiency, in particular the exhaust heat pump WP at a flow rate of 300 m ³ / per hour within the ventilation systems L1, L2 annual work rates of up to 6.2.

In the second ventilation system L2 as explained no supply air feedthrough elements 100 _To need. Thus, no supply air ventilation system L _{To be} executed, which is designed in this second ventilation system L2, the assembly effort less. As a result, a minimal intervention in the building shell or renovations in the building fabric is necessary, whereby the second ventilation system L2 is predestined for renovations.

In the preceding description it is clear that the two ventilation systems L1, L2 can be coupled in different ways with other systems, so that in particular an increase in efficiency of the coupled with the ventilation systems L1, L2 heating system HS can be achieved.

When new or retrofitting such ventilation systems L1, L2, as explained, there are a number of building regulations requirements that have been taken into account within the ventilation systems L1, L2, so that the stated object is to provide a ventilation system to provide the building regulations Meets requirements and easy, safe and inexpensive to reinstall or retrofit is.

As building regulations requirements, the focus is on fire protection and sound insulation. In addition, within the description, information is given on the building physics configurations which are of relevance in connection with the installation of a ventilation system L1, L2 according to the invention.

The 3A and 4A each show a horizontal section through the outside with a flame-retardant insulating material insulated wall G1 of the building G with a feed-through element 100 _Off , 100 _To as part of a ventilation system after 1 or 2 , where the 3A the arrangement of the feedthrough element in the assembly as exhaust air feedthrough element 100 _From and to 4A the arrangement of the feedthrough element in the assembly as supply air feedthrough element 100 _To show.

The 3A . 4A are described together below, focusing on the differences between the 3A . 4A will be received.

In the 3A and 4A is the wall G1, the respective lead-through element 100 _Off , 100 _To and the insulation D, D1 shown cut in a horizontal plane.

On the inside, the wall G1 is provided with a plaster G11. The inside is the side with the rooms of the building G defined. The outside of the facade side of the building G is defined, which with an insulation D, D1, D2, D3 (see also the 3B and 4B is provided. The 3B and 4B will be explained in more detail.

The 3A and 4A differ with respect to the flow direction to be discharged from the building G or to be supplied to the building G air.

In 3A the exhaust air flow (in 3A from left to right in the direction of arrow P1) from the spaces of the building G from a first end 1 the feedthrough element 100 _From above the bushing element 100 _Off to a silencer 300 that's on a second page 2 the feedthrough element 100 _Off , 100 _{To be} arranged in one on the Outside of the building G-lying exhaust ventilation system L _Ab out.

In 4A the supply air flow (in 4A from right to left in the direction of arrow P1) via the supply air ventilation system L _Zu on the outside of the building G via the silencer, which is also located on the outside of the building G. 300 over the bushing element 100 _{To be led} into the rooms of the building G.

The 5 shows a hollow body 100 the base as a non-assembled feedthrough element 100 _Off , 100 _{To form} in a kind of enveloping body, which in the 3A . 3B such as 4A . 4B is made up.

In the embodiment, the enveloping body 100 from a cylindrical tube, which is made of galvanized sheet steel, for example.

The envelope body 100 is fixed in an opening, in particular a facade opening, for example, walled, which is why in the 3A and 4A a mortar G12 is shown with a minimum Einmörtelungsbereich G13.

The envelope body 100 is grouted because of the necessary airtightness between the inside of the building G and the outside of the building G at least in the illustrated minimum Einmörtelungsbereich G13, wherein the Einmörtelungsbereich G13 in the illustration at the first end 1 of the envelope 100 begins and in the embodiment substantially to the formed as a positioning bead 101 the feedthrough element 100 _Off , 100 _To extend.

According to the invention, the enveloping body is provided 100 in a length that is independent of the wall thickness of the building G. It is planned, see 5 in that the enveloping body 100 a first of the wall G1 packing area 100-K1 whose length remains unchanged. A second packaging area 100-K2 is starting from the positioning element 101 to the second end 2 formed, this second confection area 100-K2 with its opposite the first confection area 100-K1 smaller diameter than excess length is formed. In this case, the excess length has a mark for a minimum length of the excess length, up to which the excess length cut off, that can be shortened.

During assembly of the enveloping body 100 in wall G1 of building G, the first end is adjacent 1 on the inside of the building wall G1 and the excess length of the second packaging area 100-K2 protrudes beyond the outside of the building wall G1 and is shortened on the outside wall accordingly, so that the unassembled envelope body 100 for building walls G1 of different wall thickness can be used variably. That means finally that the prefabricated envelope body 100 , which is finally the unassembled implementing element 100 _Off , 100 _To forms at each wall thickness of the wall G1 of the building G is variably adjustable.

The mortar G12 is no longer visible later because it is covered with the interior plaster G11.

The envelope body 100 can be assembled from the inside after installation in the façade opening.

In order to prevent a flashover between the spaces connected to air channels LK, is in the respective lead-through element 100 _Off , 100 _{Toward the} direction of flow P1, a fire protection shut-off device 120A , In particular, a flame-safety shut-off device installed.

This flame fire safety shut-off device 120A forms in each penetration of the building wall G1 a foreclosure against flashover, so that form separate fire compartments in the building G. The modular installation of the flame-protection shut-off device 120A takes place from the inside, with an already mentioned first precaution 101 as positioning element 101 is formed in the manner of a bead. Advantageously, the built-in parts 120A and 120B Accessible at any time for inspections and replaceable if necessary.

In the area of the bead becomes the inner diameter of the enveloping body 100 smaller, so that when inserting the flame fire shut-off device 120A within the envelope 100 automatically forms a stop. As a result, the exact positioning of the flame-safety shut-off device is advantageously 120A within the implementing element 100 _Off , 100 _{To be} assured and a worker works flawlessly according to a simple instruction.

For protection against cold smoke is also preferably in combination with the flame-safety shut-off device 120A a cold smoke fire barrier device 120B intended.

In an exhaust passage element 100 _From the worker is first the cold smoke fire protection device 120B modular in the enveloping body 100 plugged and up to the positioning element 101 pushed to stop. Only then does the described assembly of the flame fire shut-off device 120A ,

For a supply air feedthrough element 100 _To be the first of the worker's flame fire shut-off device 120A modular in the enveloping body 100 plugged and up to the positioning element 101 pushed to stop. Only then does the described assembly of the cold smoke fire protection device 120 , because the flow direction P1 in the supply air feedthrough element 100 _To the exhaust passage member 100 _{From the} other way round.

As the 3A . 4A clarify the flame fire shut-off device 120A and the cold smoke fire barrier device 120B as a function of the flow direction according to the arrow P1 in the enveloping body 100 introduced that the respective closing side 120A-S . 120B-S is flowed first seen in the flow direction P1, that is in 3A are the closing sides 120A-S . 120B-S room side towards the first end 1 of the envelope 100 arranged and in 4A are the closing sides 120A-S . 120B-S towards the second end 2 of the envelope 100 arranged. As a result, in combined use, a flashover and a cold smoke barrier are present, which is effective in terms of fire protection measure according to the flow direction P1 and prevents the spread of fire and cold smoke in case of fire.

The integration of the flame-safety shut-off device 120A and the cold smoke fire barrier device 120B takes place according to the invention modular and is advantageously after installation of the envelope 100 executed in the building wall G1 from the inside. The packaging of the envelope 100 Thus, for example, regardless of the construction of the exhaust air ventilation system or the supply air ventilation system L _Ab , L L _Zu and regardless of the mounting of the insulation D, D1, D2. In the assembly process, this independence is an advantage.

In addition to the very important fire protection is the packaging of the envelope body 100 to a complete lead-through element 100 _Off , 100 _Too further. In the area of the first end 1 is inventively a mounting socket 150 in the envelope 100 plugged in. This mounting neck 150 is flanged at one end and thus forms at the rear of the first end 1 of the envelope 100 a stop. This modular mountable from the inside mounting socket 150 makes a floor with a stop.

By this configuration, in the mounting stub 150 modular a grid element 130 and / or a grease filter 140 are inserted, which automatically find their position on the bottom stop, so that again can be worked by the worker error-free and the assembly of position-safe elements 130 and or 140 is automatically feasible.

In the embodiment, the grease filter 140 in the grid element 130 integrally formed, so that a single assembly step for accurate positioning confection is sufficient to use the grid element 130 to prevent the passage of entrained particles and to allow the deposition of fat. The grid element 130 In preferred embodiments, has a mesh size of less than or equal to </ = 10 mm.

Not shown but as a further embodiment, it is provided that to improve the room air hygiene in particular for feedthrough elements 100 _{To be integrated} in the supply air ventilation system L _To pollen filter. Thus, according to the invention, preferably activated carbon filters are used in the central ventilation system L and pollen filters in the respective feedthrough elements individually or in combination.

On the inside of the building wall G1, that is at the first end 1 or in the first end 1 of the envelope 100 also becomes a holding element 160 intended. This holding element 160 is either in the mounting socket 150 integrated or insofar such a mounting socket 150 no use takes place on the inside of the envelope 100 arranged directly. The holding element 160 forms the counterpart to a connection element 110A an exhaust air or supply air element 110 ,

The exhaust air or supply air element 110 can thus easily via its connection element 110A with the corresponding retaining element 160 be positively or non-positively connected.

For example, a bayonet closure or a screw cap or the like is proposed.

This exhaust air or supply air element 110A is commonly referred to as a shut-off element 110 , which can take over the following functions.

The exhaust air or supply air element 110A forms the room-side cover and allows easy access to the intended as replacement parts confectioning elements such. B. the grid element 130 and / or the grease filter 140 and / or a pollen filter, or allows replacement of the flame-arrester shut-off device 120A and / or the cold smoke fire barrier device 120B , The easy demonstrability generally allows easy access to Repair purposes within the respective bushing element 100 _Off , 100 _To .

For a complete dismantling of the assembly elements, even the air ducts of the respective exhaust ventilation system or of the supply air ventilation system L _Down L are _to be reached, so that, for. B. is made possible by means of vacuum cleaner systems a channel cleaning.

With conventional permanently installed elements, these advantageous exchange, repair or access options do not exist.

It is clear that the maintenance or repair work, in particular the replacement of confectioning elements can be made advantageously without any tools.

In a preferred embodiment of the invention, the respective exhaust air or supply air element 110 following technical features.

They are also designed such that they are designed as a kind of aerodynamic aperture, so that in an advantageous manner drafts on the respective lead-through element 100 _Off , 100 _To be avoided.

It is provided for the user, the volume flow of the exhaust air or supply air 110 manually adjustable.

Also proposed is an automatic humidity and temperature-controlled design of the exhaust air or supply air 110 to be used, so that regardless of the intervention of the user, an automatic regulation of the volume flow as a function of the room humidity and / or the room temperature takes place.

The described implementation elements 100 ; 100 _To , 100 _From allow a relatively free choice of exhaust or Zuluftelementen 110 different manufacturers.

As the 3A . 4A in conjunction with the 3B . 4B show is at a second end 2 the feedthrough element 100 _Off , 100 _To a muffler 300 connected by the description of the 6 . 7 and 8th is clarified in more detail.

The silencer 300 and the air ducts LK of the respective exhaust air ventilation system L _Ab or supply air ventilation system L _to lie in the plane of the insulation D or parallel to the facade side outer surface of the building G.

Between the silencers 300 and the air passages LK and the outer wall surface of the wall G1 insulating strips D3 are arranged, which have an insulating effect and prevent the transmission of sound between said components.

The insulation D consists of several insulating elements, in particular on the insulating elements D1, D2 in the environment of a muffler 300 and a ventilation duct LK is received.

The 3B and 4B clarify that provided as insulating elements D1 angled elements and straight elements D2 are provided. The angle elements D1 engage over a silencer 300 or under a silencer 300 the ventilation systems L1, L2.

In the respective vertical section 3B and 4B It is clear that a straight vent D2 is arranged as a connection between two angled elements vertically on the ventilation duct LK.

Due to the laying of cables on the outside of the building G, the air ducts LK and the silencer change in the area of the insulation D 300 the insulation properties, since the exemplary insulating elements described D1, D2 in the range of the muffler 300 and the air ducts LK have a smaller thickness than the other insulating elements which are not in the region of the mounted air ducts LK, 300 are arranged.

The silencers 300 Air ducts represent LK with special sound-insulating properties.

According to the invention, it is provided that the channel-covering insulation elements D1, D2 have at least 2/3 of the total insulation thickness, whereby the danger of dew point undershooting of the air in the air channels LK 300 is avoided, as experiments have shown.

Further, that is to further ensure the absence of dew point undershoot the air in the air ducts LK 300 It is proposed to use an insulating material in this area, which has an improved heat transfer coefficient, so that in the channel-covering area, despite low density of the insulating elements D1, D2, similar values are achieved, as in the remaining area of the insulation D, so that even in the places where the insulating element D1, D2 on the air ducts LK 300 are arranged advantageously no dew point below occurs.

On the measure according to the invention the direct connection of a silencer 300 to the feedthrough element 100 _Off , 100 _{To have} already been received.

The ventilation system L _Ab , L _Zu Included with the silencer 300 concrete sound insulation measure for the reduction of the sound is discussed in more detail below.

As already explained, the hollow body 100 the second packaging area 100-K2 on, which can be shortened as needed. However, the shortening is done in practice only up to a length that still allows a muffler spigot 310 in the connecting piece 102 or on the connecting piece 102 the feedthrough element 100 _To , 100 _From the second packaging area 100-K2 is pluggable.

The seal between the silencer connector 310 and the connecting piece 102 the feedthrough element 100 _To , 100 _From done by a sealing element 170 ( 3A . 4A ), in particular a rubber seal or a rubber band.

The silencer 300 is installed as a ventilation duct LK wherever soundproofing measures are necessary. Advantageously, the muffler comprises 300 Arrangements against external noise and against the so-called telephone sound. In the case of telephone sound, there is a transmission of noise via the ventilation ducts LK, 300 from one room to another room.

In the case of external noise, external noise is transmitted via the ventilation ducts LK, 300 into the rooms of the building G.

Through the design of the silencer connection piece 310 becomes the muffler 300 , as in 6 is shown as a prefabricated L-element, in particular made of a galvanized sheet steel, alternatively made of stainless steel already. It has been found that flat rectangular channels for the arrangement on walls in terms of space requirements and the volume flows to be observed in the ventilation ducts LK, 300 represent the optimum. The ventilation ducts LK, 300 are also made of galvanized sheet steel, alternatively made of stainless steel.

The silencer 300 has a reduction 320 for connection to standardized ventilation ducts LK.

The silencer 300 itself has to accommodate sound-absorbing lining 330 (against external noise) and sound-absorbing backdrops 340 against the in the ventilation ducts LK, 300 transferable telephony sound on a larger volume, which is why the end reduction 320 is provided.

The sound-absorbing backdrops 340 each form in the flow direction P1 a sound path, which to avoid the telephone noise with the sound-absorbing lining 330 interacts. The sound-absorbing lining 330 in turn reduces the negative sound transmission from the outside.

In the exemplary embodiment, a silencer is provided at each of the spaces to be ventilated or to be ventilated 300 arranged, in particular the 3B and 4B clarify.

In summary, the trained as an angle arc muffler 300 silenced and has soundproofing scenes 340 as well as a circumferential lining 330 non-combustible materials (A2), in particular mineral and / or rock wool DIN 4102 on.

The soundproofing measures are supplemented by the mentioned D3 insulation strips, which are located between the silencers 300 and the air passages LK and the outer wall surface of the wall G1 of the building G are arranged.

The 3B and 4B show in each vertical section each one arranged in the building wall G1 exhaust passage member 100 _From and in an inspection opening and a supply air feedthrough element 100 _To (according to 3B ) or - conversely - a supply air feedthrough element 100 _To in the building wall G1 and in an inspection opening an exhaust duct 100 _From (according to 4B ).

The respective implementing elements 100 _Off , 100 _To in the inspection opening preferably have the fire protection equipment, which consists in that the lead-through element 100 _To , 100 _Ab as a non-assembled hollow body 100 is formed, the at least one positioning element 101 has, by modular installation a positionally accurate packaging with at least one fire protection device 120 allows, with the fire protection device 120 a flame fire safety shut-off device 120A , in particular a fire damper for protection against flames and / or a cold smoke fire protection barrier device 120B for protection against cold smoke.

The invention has summarized advantages in the construction, maintenance and repair of the ventilation system L.
