Description

Modular and façade-integrated ventilation and air conditioning system

The invention relates to a (nodular climate system having at least one outdoor air unit, at least one exhaust air unit, at least one heat recovery unit, at least one convector unit and at least one control and / or regulating unit, as well as a building and an air conditioning and ventilation unit consists of modular units of such a climate system.

Air handling units and air conditioning systems can be installed directly on the inside of the façade of buildings. This allows the elimination of central ventilation systems and air distribution networks, which are arranged in the rooms of the building. This can advantageously be dispensed with a large installation space, these ventilation systems and Luftverteilnetze require, which affects the height of the floors or the entire structure on the one hand costly and on the other hand requires special cladding measures, such. suspended interior ceilings. The installation of ventilation devices directly on the inner facade also allows a largely individual ventilation and air conditioning for each room or facade segment. As a rule, this functional advantage can also be used to save energy.

A problem with previous Fassadenlüftungs- and air conditioning systems consists in the miniaturization of the individual components and the placement of the individual functional elements in the building or the inner facade such that the components possible, and also in the case of largely glazed

Facades, are not visually visible and do not reduce the usable area.

On the other hand, with excessive miniaturization of the components there is a risk that the performance of these systems will be limited. Previous systems with heat recovery and / or integrated heating or cooling convectors are either installed as a flat unit near the facade in the raised floor of a building or mounted as a flat panel on the inner facade or are designed as a parapet chest with integrated sill, which is placed on the inner facade , However, such systems can not be individually adapted to the conditions of a building and are usually not very variable.

For this purpose, WO 2008/037582 A1 proposes a building in which a receiving space is formed between the inside of the facade and the outer end face of the storey ceilings, in which functional elements of the building system technology can be accommodated. A disadvantage of this solution is that the receiving space increases the external dimensions of the building or reduces the usable area within the building for given external dimensions.

It is therefore an object of the present invention to provide a climate system of the type mentioned above which can be flexibly adapted to the requirements of a building or a part thereof and at the same time requires a minimum of installation space.

This object is achieved essentially with a climate system which is formed from modular units, of which at least one unit is integrated into a facade segment of a building. In other words, the system according to the invention of a plurality of preferably also replaceable functional elements is modular, which are not integrated into an integrated device concept. The individual units of the system can be arranged at different locations within the building, without one for example, is formed by a common housing defined integrated device.

According to the invention, the units that form functional elements are modularized in such a way that optimized configurations can be implemented for different applications, and that individual functional elements can either be integrated into facade elements and / or into the (double) floor and / or wall and / or ceiling construction of a room unit of the building, the facade of which is formed by at least one facade segment. This makes it possible to construct and arrange certain units (functional elements) so that they supply space units that belong to at least two façade axes.

According to a preferred embodiment, an outside air unit fulfills the functions of external air supply and / or outside air filtration. This can be achieved by having the outside air unit an outside air fan, an outside air filter and / or an outside air shutter unit.

The exhaust air unit preferably fulfills the basic function of the exhaust air extraction and has, for example, an exhaust air fan and possibly an exhaust air filter and / or an exhaust air shutter unit.

In order to use the heat contained in the exhaust air, a heat recovery unit may be provided, which is equipped at least with an air-to-air heat exchanger and a condensate drain device. In addition, this heat recovery unit may be equipped with outdoor and exhaust air shutter units, an outside air filter and / or a bypass door unit and / or a bypass duct. In order to achieve the largest possible flat and flat design, the air-to-air heat exchanger can also be used as Functional unit may be formed with a plurality of individual air-air heat exchanger elements in front or bottom parallel connection or series connection.

Furthermore, it is preferred if the convector unit has a single convector element or is designed as a fan convector device for respectively heating and / or cooling the outside and / or room air, and / or is designed as an induction convector device, and / or is designed as an integrated combination ventilation and air conditioning unit, which in turn contains both fan and induction temperature control modules as integral components. For this purpose, reference is made in full to DE 10 2008 007 641, which describes a combination induction fan convector, in which the ventilation unit is formed with at least one heat exchanger or convector for the temperature control of air, which is associated with at least one fan Temperierungsmodul the ventilation unit wherein the fan Temperierungsmodul has at least one fan for forcing a flow of air sucked through at least one suction port of the ventilation device in thermal contact with the heat exchanger or convector past this. In this case, the ventilation unit additionally has at least one induction tempering module operating according to the induction principle.

In addition, in the system according to the invention, at least one control and regulation unit can be provided which fulfills at least one of the following functions: control and / or regulation of outdoor and supply air fans arranged cascaded in the functional area outside or supply air, and / or or regulation of in the functional area exhaust air or exhaust air removal possibly cascaded to each other exhaust air and exhaust fans, control and / or regulation of the ratio between outdoor and exhaust air volume flow depending on the system configuration, control and / or regulation of the outdoor and exhaust air flaps, control and / or regulation of the wind pressure and windage compensation function, tion and / or regulation of the antifreeze and supply comfort temperature function, control and / or regulation of the bypass function, control and / or regulation of the filter replacement and cleaning function, control and / or regulation of the outdoor and indoor convector function, control and / or regulation of the room temperature function, control and / or regulation of the air exchange or room air quality function, control of energy saving functions, alarm and alarm functions. This unit may also have a network interface and / or a building control technology interface.

According to the invention, a facade segment is understood to mean any unit composed of various individual elements, from which a modern glass and / or aluminum facade is constructed. Usually, such a façade is constructed from various basic elements which can be designed as glass elements, for example in the form of an openable or non-openable window sash, and / or as non-transparent panel elements. A façade segment represents the facade for at least one segment or at least one so-called axis of a projectile.

The individual elements of the façade segments can be arranged vertically to the floor slab (facade segment panel V element) or horizontally (facade segment panel H element). Corresponding or the at least these facade segment elements enclosing parts of the constructive façade components such as posts and bars can each represent an integral part of the previously designated elements. Further, the facade segments may be formed as a face segment A-element representing the facade for the part of the façade segment belonging to the front of the floor segment belonging to the facade segment, or as a face segment B-element, the facade for the belonging to a facade segment part of the front side of belonging to the facade segment double floor construction. The height dimension of the front tense-segment B elements at least the dimension from the upper edge of the floor slab belonging to the facade segment to the upper edge of the double-floor construction installed on this floor slab. Alternatively, this height dimension can be increased by a base size of about 200 mm, with this base size extending from the top of the double floor construction installed on this floor ceiling upwards.

In a further development of the inventive concept, it is provided that additional line elements for connection and connection of the outside air unit, the exhaust unit, the heat recovery unit, the convector unit and the control and / or regulating unit are provided in the air conditioning system. Also, these line elements, the passage of gases such. Outdoor, room or waste or exhaust air, fluids such. Heating or cooling water, and / or electricity can serve, are preferably modular in various Ausfüh- tion or confection forms available, so that individually tailored to a climate or ventilation equipment components can be used.

Alternatively or in addition to the features described above, the invention relates to a modular air conditioning system for use in a building having a facade formed at least partially by facade segment elements with facade profiles and / or window elements enclosed by window profiles, wherein the air conditioning system has at least one heat exchanger is integrated in a facade profile and / or in a window profile. In this case, the heat exchanger can be designed as a channel-shaped air-air heat exchanger. The use of a facade profile and / or a window profile as a heat exchanger offers considerable advantages both in terms of the design of the facade, in terms of space and in terms of the number of components required for air conditioning. It is preferred if the at least one modular unit integrated in a facade segment element of a building forms a physical, structural and / or functional unit with the facade segment element. Thus, the at least one integrated into a facade segment of a building unit can be mounted with this as a prefabricated unit to the building.

The invention further relates to an air conditioning and ventilation system, which consists of the modular units of an air conditioning and ventilation system of the type mentioned above, and a building with a facade, which consists of a plurality of facade segments, wherein in at least one of the facade segments a modular unit of an air conditioning and ventilation system of the above type is integrated.

The invention will be explained in more detail by means of embodiments and with reference to the drawings.

The configuration and integration of the units (functional elements) of a modular and integrated façade climate control system according to the invention and their integration into modern facade segments (or façade segment elements) can, for example, be as described below. In this context, integration means that a physically and constructively and partially also a functional unit arises from the façade segment (or façade segment element) and the at least one unit of the climate system. This unit can also be advantageously prefabricated and assembled as a unit on the building.

Outside air unit

According to the invention, an outside air unit 8 of the air-conditioning system can be embodied, for example, in a facade segment panel V element 2 (see FIG. 3), a facade element panel H element 1 (see FIGS. 1 or 2), a face segment segment. A-element 3 (see Figures 4a and 4b) or a front-side segment B-element 4, 5, 6 (see Figures 5a to 7b) are integrated. A complete integration of an outside air unit in one of said facade segment elements has the advantage that the design of the façade connection can be optimized with regard to the integration of the outside air opening into the façade segment element, the integration of the rain and splash protection into the facade segment element, the integration of the spray water outlet into the façade construction and the integration of the outside air fan. Furthermore, a particularly high degree of tightness of the external air facade connection can be achieved inside with a high degree of prefabrication and good space utilization or a compact design.

The outside air supply into a closed space to the environment in the building is preferably carried out by supplying the generated by this unit outside air volume flow through, for example, flexible and laid in false floor flat channels directly into a heat recovery unit. Alternatively, the outside air supply can also be done by, for example, flexible and laid in false floor flat channels directly into at least one convector unit.

According to the invention, the facade segment can be designed in such a way that the part required for receiving the outside air unit is designed as an installation space or a housing. This preferably extends from the facade or the facade segment panel H element or the facade segment panel V element on at least a small part or the entire length of the facade segment panel H element or the façade segment Panel V-Elements inside into the room. The installation space or housing may also extend inwardly from the facade or the face segment B element to at least a portion of or the entire length of the face segment B element. In this case, the installation space or the housing is completely integrated into the cavity of a double floor, which can be provided with inspection louvers to be placed, for example, which can be covered by a grate can. Alternatively, it is possible to make accessible the installation space or the housing accessible and to integrate in the (double) floor, that connects an inspection hatch at the same height and inwardly thereto.

Further, the installation space or the housing or the Außenluftein- unit itself may be formed so that they extend at least partially and by a Sockemmaß on the double or Fertigfußboden on a small part or the entire length of the facade segment in the room.

According to a further embodiment, the installation space or housing is an outwardly formed projection in a facade segment panel H element or a facade segment panel V element or a stimulus segment A element or a front side segment B Element formed. This has the advantage that no large distance between the facade and the floor slab construction or a large thickness or depth of the facade construction must be provided. This would be detrimental to the Erfindungsleitendesank, since a consistently larger facade depth also larger building dimensions or reduced internal building dimensions and thus a smaller effective area at given maximum building exterior dimensions causes. Alternatively, the outdoor air unit can be integrated in any convector unit of the air conditioning system or in certain and for this unit structurally expanded convector units. The outdoor air unit can also be integrated as a separate functional unit in the cavity of a double floor construction.

exhaust unit

The exhaust air unit 9 of a climate system according to the invention can also be used, for example, in a facade segment panel V element 2, a facade element panel H element 1, a front side segment A element 3 or a front panel. tensegment B element 4, 5 or 6 are integrated. This is with the above explained in terms of the outside air unit advantages in terms of integration of the exhaust air opening in the facade segment, the integration of rain and spray water protection in the facade segment, the integration of Spritzwas- serablaufs in the facade construction and the integration of the exhaust fan and in terms of the degree of tightness the façade connection inside with a high degree of prefabrication and a good space utilization or a compact design.

The exhaust air intake from a closed to the environment space of the building is preferably carried out by suction of the generated by this unit exhaust air volume flow. This is done either directly from the space to be vented by, for example, flexible and false floor laid flat ducts and by at least one outlet valve or exhaust grille, e.g. as may be required for the generation of a cross-ventilation flow optimally positioned. Alternatively, this is done directly from the space to be vented by, for example, the parts of the structural facade elements, such as posts and bars, which surround the above-mentioned facade segments and are designed and connected accordingly, as well as at least one in this constructive facade components integrated space side Exhaust valve or exhaust grille, which can be positioned close to the ceiling, for example, as required for the generation of an optimal vent flow. With regard to an inventively optimized use of space, this integration is carried out, for example, in a facade segment panel H element or a facade segment panel V element or a front side segment AElement or a front side segment B element.

As explained above with regard to the outdoor air unit, the facade segment for the exhaust air unit can be designed such that the part required for receiving the exhaust air unit can be designed as an installation space or as a housing. is formed, which as described above in the facade and / or the double or prefabricated floor can be integrated. This in turn leads to a minimization of the required space and thus to smaller external dimensions of the building or an increased effective area at given outer dimensions of the building. Alternatively, the exhaust unit can be integrated into a convector unit or as a separate functional unit in the cavity of a double floor construction or in a partition located further in the space to be vented - which separates the space from the access corridor, for example. In principle, it is also possible to arrange the exhaust air unit at any other suitable point in the space enclosed by the abovementioned facade segments to the outside world or environment in the building.

heat recovery unit

According to the invention and depending on the configuration of a modular and façade-integrated ventilation and air-conditioning system according to the invention, a heat recovery unit 10 can be, for example, a facade segment panel V element 2, a facade segment panel H element 1 or a front end segment B element 4, 5, 6 are integrated. This advantageously offers the possibility of exploiting the large surface area of such façade segment elements for the heat exchanger, especially when compared to the base area of conventional facade ventilation devices. In addition, due to the overall large heat transfer surface of the heat exchanger fins between the outside and the exhaust air can thus achieve an extremely flat design or an extremely low overall depth with high heat recovery performance. This applies to parallel arrangement of the heat exchanger to the facade segment element such that the heat exchanger fins are arranged parallel to the facade. The construction of a façade segment panel V element or a facade segment panel H element with integrated heat recovery unit can look like this from outside or distal to inside or proximal (description without associated or at least these facades - Segment-enclosing parts of constructive façade components such as posts and bars):

• Exterior panel-side facade panel material panel, e.g. Made of sheet steel, aluminum, glass, wood or high-strength pressed mineral material.

• Subsequently or housing-sided flat insulating and insulating material layer made of non-combustible insulating or insulating material or vacuum

Insulating or insulating material.

• Air-to-air fin heat exchangers made of plastic or aluminum fins.

• Flat insulating and insulating material layer made of non-combustible insulating or insulating material or vacuum insulating or insulating material.

• Optional additional and proximal baffle plate or air duct. This plate or this channel has an overall area on a cavity which perceives the following three functions in the core: o distribution of the outside air, which has already flowed through the air / air heat exchanger, to a freely positionable in the air guide panel plate

Zuluftaustrittsöffnung. o Additional insulating function by the Luftleitpanel plate air flowing through, since the Luftleitpanel plate air flowing through in the air / air heat exchanger has already been preheated and on the other hand by the arranged between the air / air heat exchanger and Luftleitpanel plate insulating and Insulating layer is isolated or insulated according to building distally. o Bypass function through an optionally usable direct passage of the outside air through the air guide panel plate. • In addition, the exterior façade panel material panel can be provided with external or exhaust air flue on the panel panel side or the panel panel end provided for this purpose - this is the floor-side or bottom panel end, for example - in a façade segment panel V element - Performed voltages that can be provided with attached to this outer façade panel material plate Lufteinström- / Ausström profile rail. If the outer or exhaust air openings are covered by such an air inflow / outflow profile rail, this is provided with a separating bulkhead, which separates the outer and exhaust air volume flows from one another and is designed such that it can be attached to the

Deriving separation point in opposite directions. These air inflow / outflow profile rails may also be fitted with outermost or exhaust air openings in the outer facade panel material panel with outer and exhaust filters of a coarse filter class, respectively. These filters can be easily accessible and quickly replaced by appropriately placed in the interior facade panel material plate or the air baffle and closed with flaps inspection and maintenance.

In addition, the outer facade panel material plate may be provided on the panel plate side and the panel plate end provided therefor, that is, in a facade panel V element, e.g. the

Bottom-side and bottom-plate ends, respectively - with outward or outgoing air openings, which can be provided with air inflow / outflow profile rail fitted to this outer façade panel material plate. If the outer or exhaust air openings are covered by such Lufteinström- / Ausström rail this is provided with a bulkhead, which separates the outside and exhaust air volume flow from each other and is designed so that it dissipates it at the separation point in opposite directions. These air inflow / outflow profile rails may also be provided with external or exhaust air openings in the exterior façade panel material panel with external or exhaust air openings. air filters of a coarse filter class. These filters can be easily accessible and quickly replaced by appropriately placed in the interior facade panel material plate or the air baffle and closed with flaps inspection and maintenance. • At the same time, the heat recovery unit or the Außenbzw. Exhaust air openings and the air-air-plate heat exchanger and that the condensate collecting trough to each other in the facade segment panel V-element or the facade segment panel H element arranged or positioned so that the condensate collection tray with condensate Drain device can simultaneously function as a drain device for possibly still penetrating through the outside or exhaust air openings in the heat recovery unit splashing or from the outside air directly after entry or flow through the heat recovery unit precipitated moisture.

The façade profiles surrounding such a façade segment element can be used for the further and, as it were, quasi-integrated discharge of condensate, spray water or precipitated moisture.

When integrating a heat recovery unit into a face segment B-element, it may be necessary to increase the height of the face segment B elements for integrating a cross or counterflow heat exchanger over the given height dimension from the distance of the top of the bare floor to the top of the false floor addition to increase a so-called socket size.

This can be omitted if the heat exchanger or the heat exchanger lamellae are alternatively arranged orthogonal to the facade segment element or facade segment and the heat exchanger correspondingly extends inwardly into the room, such as directly along a room wall (vertically orthogonal arrangement) or in particular in the space between the top of the Rohfußbodens and the lower edge of the false floor (horizontal orthogonal arrangement) is arranged. In this case, however, the heat exchanger fins are arranged only quasi orthogonal to the facade segment element or façade segment, since the heat exchanger fins must be tilted in relation to the floor level in at least one dimension to allow the necessary condensate drain.

The integration of a heat recovery unit in a Fassadensegment- element also allows a high degree of prefabrication and a reduction of installation effort, since the installation of the heat recovery unit can be done simultaneously with the installation of the facade.

As explained above with respect to the outdoor air unit, the facade segment member for the heat recovery unit may be configured so that the part required for receiving the heat recovery unit is formed as an installation space or housing, as described above in the facade and / or the double or Fertigfußboden is integrable. This in turn leads to a minimization of the required space and thus to lower external dimensions of the building or an increased floor space with given external dimensions of the building. Alternatively, the heat recovery unit can be integrated as a separate functional unit in the cavity of a double floor construction.

Konvektoreinheit

A convector unit 7 may according to the invention, for example, in a facade segment panel V element 2 or a facade segment panel H element. 1 to get integrated. This advantageously offers the possibility of designing the facade segment panel V element or the facade segment panel H element in such a way that the installation or the mounting or the mounting or mounting of at least one convector unit in a parallel arrangement of these Unit to the facade segment element can be done extremely quickly and easily. In this case, the underside of the convector unit is positioned flat on the provided with an insulating material coating inner surface of the facade segment panel V-element or the facade segment panel H element.

The integration of a convector unit in a facade segment element also allows a high degree of prefabrication and a reduction of assembly costs, since the assembly of the convector unit can be carried out simultaneously with the assembly of the facade. The inner or room-side cladding of the façade segment element provided with a convector unit can be adapted to the requirements of the integrated convector unit, in particular with regard to ventilation, flow and air conditioning technology, as well as installation and service, and designed as an integral part of the facade segments.

Control and regulation unit

The control and regulation unit is preferably integrated into a separate and easily accessible installation space, which is provided as part of an outdoor air unit, an exhaust air unit, a heat recovery unit or a convector unit. Alternatively, the control and regulation unit can also be placed in any other suitable location in the space enclosed by facade segments in the building or integrated into the cavity of a double floor construction in just this room. 1st embodiment

According to a preferred embodiment of the invention, the modular and integrated facade climate system is constructed as follows:

The heat recovery unit 10, optionally together with an outside air unit 8, is integrated in a front side segment B element 4, 5, 6 (see, for example, FIGS. 6a and 6b) or in a facade segment panel V element 2. Alternatively, the outside air unit is provided as a separate functional unit and not integrated into a facade segmental element. The exhaust air or continuous air unit 9, if necessary together with a heat recovery unit 10, integrated into a facade segment panel V element 2 or provided as a separate functional unit and not integrated into a facade element.

In this case, this front-end segment B-element can be designed so that the required for receiving the units part is formed as a installation space or housing, of the end face segment B-element over a large part of the length or the entire length of the facade segment - Element extends inwards into the room. If the installation space or the front side segment B element has a height that is slightly greater than the height dimension from the top edge of the raw floor to the top edge of the double bottom, the heat recovery unit can be designed as a cross and / or countercurrent heat exchanger.

Alternatively, the installation space or the face segment B-element may be partially integrated into the cavity of a false floor and extend partially and by a Socket over the double or Fertigfußboden on a small part or the entire length of the facade segment element in the room. This means that the installation space or the front-end segment B element has a somewhat greater width in the region of the end face. segment B element has, which corresponds to the front of the free raised floor height. As a result, the installation space or the front-side segment B element extends from the facade into the double-floor free space for a part and for a part of the width of the installation space or the front-side segment B element. This part of the installation space or of the front side segment B element can advantageously be provided for the integration of components or partial units of the heat recovery unit. These are, for example, a bypass flap unit, a bypass air duct and a condensate drain device, an outside air fan unit, an outside air filter or an outside air filter, an outside air shutter flap unit, an exhaust air fan unit, an exhaust air filtration or an exhaust air filter and / or an exhaust air flap unit.

Such an arrangement of these subunits integrated into the heat recovery unit has the advantage that they can be made more easily accessible and accessible in a part of the installation space or front side segment B element placed in the free double bottom space, for example by means of inspection hatches arranged correspondingly and in mirror image relation to one another in the raised floor and in this part of the installation space or the face segment B element.

Here, the outside air fan unit, the outside air filtering and the outside air filter, the bypass damper unit, the bypass air duct, the exhaust air fan unit, the exhaust air filtration and the exhaust filter are preferably as each separate units or modules placed in the free cavity of a double bottom of a suitable and further space on the spot. This arrangement of these units integrated into the heat recovery unit has the advantage that they can be made more accessible and accessible there. The ventilation connection of this and the following units with the heat recovery unit is then carried out by, for example, flexible and laid in raised floor flat channels.

The convector unit is formed in this embodiment as a combined source air-induction or outside air convector and fan convector unit and integrated into the raised floor, that a part of the facade side aligned longitudinal side wall directly and flat with the room side longitudinal side wall of Installation space or housing of the facade segment panel V element and / or the front side segment B element is connected. The outside air guide can be made directly from the front end segment B element or the part of the facade segment panel V element located in the height of the double bottom into the convector unit. The exhaust air is preferably carried out directly from the space to be vented by e.g. flexible flat ducts laid in the raised floor and through at least one outlet valve or exhaust air grille in the part of the façade segment panel V element or the front side segment B element located in the height of the double floor into the exhaust air unit. Alternatively, the exhaust air can be discharged directly from the space to be vented by e.g. the front side segment B element or the facade segment panel V element enclosing and correspondingly trained and connected parts of the structural facade components, such as posts and bars, and by at least one in this constructive facade components room side integrated exhaust valve or exhaust grille be guided.

Such a configuration is suitable for achieving a high degree of integration between façade (construction) elements and units of the air-conditioning system, whereby at the same time an extremely space-saving and compact design can be realized. Furthermore, this allows to avoid a reduction in full glazing of the facade from the top edge of the floor to the bottom edge of the floor slab. The usable and thus rentable areas are not reduced and it can be a great air conditioning performance and good Heat or energy recovery performance can be achieved. Furthermore, the subunits can each be designed, programmed and configured with each other in such a way that the outside air volumetric flow, outgoing air or outgoing air volumetric flow, heat recovery capacity, cooling and heating capacity are optimized for the application, the individual case and the room conditions the outside air, cooling and heating power can be realized with the room air and coordinated system control of cooperating in such a system configuration functional units.

2nd embodiment

In the particularly advantageous configuration variant of a façade climate system according to the invention shown in FIGS. 7a and 7b, the convector unit is designed as a fan convector unit with integrated outside air fan unit and outside air filter or outside air filter not integrated in the facade but in the double bottom. The heat recovery unit 10 is integrated into the facade as described above, but has no bypass flap unit, bypass air passage, outside air fan unit, and outside air shutter unit.

The outside air unit is placed as a separate unit in the free cavity of a false floor, between the heat recovery unit and the convector unit with integrated outside air fan unit and outside air filter or outside air filter in a preferably fine filter class.

In this case, the two outdoor air fan units, namely the assigned in the outdoor air unit and those in the convector units different functions. These are: The outdoor air unit ensures the provision of the outside air volume flow at the outside air inflow openings of the convector units that is as free of pressure, resistance and suction as possible and quiet. The outdoor air units in the convector units ensure the lowest possible volume flow constant and constant flow of provided for the respective device outside air part volume flow through the respective device. The control, regulation and monitoring of this functional part is handled by the control and regulation unit.

At the same time, such a configuration can be used to replace the heat exchanger bypass function in the heat recovery unit. This is done by, on the one hand, leading an air duct connection directly from the outside air inflow chamber into the heat exchanger in the heat recovery unit to the outside air unit and, on the other hand, by directing an air duct connection directly from the outside air outflow chamber out of the heat exchanger in the heat recovery unit to the outside air unit.

If the outside air unit is now equipped with two outside air inflow openings and one each also alternatively opening outside air closure flap unit, the bypass function for all connected convector units can be realized in this way simply and inexpensively.

In this embodiment, also a cascading of the outside air fan function takes place. Thus, in this inventive facade air conditioning system configuration, two different outside air fan functional levels may be configured. The first outside air fan functional level is formed by the outside air fan in the outside air unit, while the second outside air fan functional level is formed by outside air fans in the convector units. These two fresh-air fan functional levels are now controlled by the control and regulation unit so that each level alone has to provide only part of the total outside-air volumetric flow capacity within an optimum range of the fan-specific characteristic curve. The series connection (in the direction of the outside air Volumetric flow seen) of the outdoor air fan functional levels causes a cascading of the critical outside air volume flow fan function.

3rd embodiment

In the particularly advantageous configuration variant of a facade-integrated ventilation and air conditioning system according to the invention shown in FIGS. 9 to 17b, the heat recovery unit 10 is designed as an air / air heat exchanger 13 integrated into the facade.

In this case, this heat recovery unit is e.g. as a facade segment panel V element 2 or facade segment panel H element 1 with or without associated or at least these facade segment elements enclosing parts of the structural facade elements such as posts and bars.

In this case, such a heat recovery unit according to the invention, which is shown in FIGS. 16 and 17 in section, constructed as follows (description without associated or at least these facade segment elements enclosing parts of the constructive façade components such as posts and bars):

Housing of facade panel material panels 11, 16. This facade panel material may e.g. Be sheet steel, aluminum sheet, glass or wood.

Internal and all-round insulating and insulating layer 12 glued together or comparable and airtight connected. This layer should preferably have excellent insulating or insulating properties with the smallest possible layer thickness, such as, for example, by using so-called mineral fiber insulation boards or vacuum insulation boards possible.

• Air / air heat exchanger 13 made of aluminum or plastic lamellae

• Condensate and moisture collection tray on the inside of a housing wall facade panel material panel with insulation board. On the outside of the façade, that is to say building-distal, an air inflow / outflow profile rail can additionally be provided on the façade panel material plate 11 arranged distally to the building. This rail is at least at the locations behind the outer and exhaust air openings in the facade panel material panel, or along its entire length, with baffles, each distally about 45 ° to the ground or down form inclined air inlet and outlet openings, equipped. The surface of these baffles is equipped with a fish-scale surface profiling that is open distally. Due to this surface texture as well as the inclination of these air baffles, a substantial impact rain repellency property and driving rain water creeping property for the outside and exhaust air openings is already achieved. Nevertheless, driving rain or moisture entering is drained via the common condensate and moisture discharge line, which connects to the internal condensate and moisture sump.

On the inside of the façade, ie building-proximal, an air-guiding panel plate 15 can additionally be provided, which is arranged in the vicinity of the proximal facade material panel plate 16. This plate has an overall surface on a cavity, the core performs the following three functions: o distribution of the outside air, which has already flowed through the air / air heat exchanger, to a freely positionable in the air guide panel inlet air outlet opening, o Additional insulation through the air flowing through the air guide panel plate, since the air flowing through the air guide panel plate in the air / air

Heat exchanger has already been preheated and on the other hand insulated by the arranged between air / air heat exchanger and Luftleitpanel plate 15 second insulating and insulating layer 14 to building-distal or insulated. o Bypass function through an optionally usable direct passage of the outside air through the air guide panel plate.

Additionally or optionally, the following functional elements can be integrated into such a heat recovery unit:

• Outdoor air fan

• Outdoor air filter

• Outdoor air shutter unit

• Outdoor air intake • Extract fan

• exhaust filter

• Exhaust air shutter unit

• Exhaust air discharge opening

• These elements are structurally arranged so that these after removal of the building proximal facade panel or panel

Air guide panel plate are easily accessible and can be easily maintained, cleaned and possibly also replaced.

According to a further aspect of the invention, regardless of the aforementioned features, the façade profiles enclosing a façade segment element and / or possibly the window profiles enclosing a window element may be designed as a heat exchanger. Such a heat exchanger is preferably an air-to-air heat exchanger and may be configured, for example, channel-shaped. The use of window profiles and / or façade profiles as heat exchangers has the advantage that existing façade or window elements can be used for air-conditioning systems without having to provide space-consuming and / or expensive additional components for this purpose. Such a solution also offers advantages from an aesthetic point of view, since the design of the façade is not impaired by the air conditioning systems. reference numeral
