Description

The invention relates to an air conditioning system, in particular an air conditioning device, preferably for heating and/or cooling a room in a building.

Air conditioners for heating and/or cooling a room, in particular a living space, are known in principle. Such air conditioners usually have an outside air flap and an exhaust air flap. Such an air conditioner is, for example, in DE 10 2004 049 621 A1 shown. According to DE 10 2004 049 621 A1 It is intended to enable stepless and mutually independent control of the outside air and exhaust air flaps to set the respective outside air requirement or the proportion of exhaust air to be discharged depending on whether recirculation mode, outside air mode or mixed air mode is present with the appropriate setting of connecting and bypass flaps. Such air flaps (such as the outside air flap and exhaust air flap described in the prior art) are used to close the flow cross section in an outside air supply air line or in an exhaust air line of the air conditioning unit when the air conditioning unit (the air conditioning system) is not in operation. This can prevent an undesired flow through the device (the system) and subsequently the connected rooms. A corresponding flap actuator can be used to actuate such air flaps.

The systems known in the prior art are still felt to be in need of improvement, particularly with regard to manufacturing technology or with regard to controlling a flap closure.

It is therefore the object of the invention to propose a ventilation and air conditioning system, in particular an air conditioning device, which can be produced in a comparatively simple manner and/or which can be controlled with regard to flap closure. Furthermore, it is the object of the invention to propose a corresponding air flap.

This object is achieved in particular by an air conditioning system, preferably an air conditioning unit, according to claim 1.

In particular, the object is achieved by a ventilation and air conditioning system, preferably an air conditioner, in particular for heating and/or cooling a room in a building, comprising at least one supply air duct (outside air-supply air line) and at least one exhaust air duct (exhaust air-exhaust air line) and at least one openable and partially closable air flap such that the air flap closes both the supply air duct and the exhaust air duct (directly) at least in sections.

A core idea of the invention is therefore in particular that a common air damper is used to (at least partially) close an outside supply air line (supply air duct) and an exhaust air line (exhaust air duct).

The air damper preferably extends at least in sections over a cross section of the air supply duct (or outdoor air supply line) and a cross section of the exhaust air duct (or exhaust air line).

At least partial (immediate) closing of the supply air duct and the exhaust air duct is to be understood in particular as meaning that the air flap is arranged at least partially in or (directly) adjacent to the corresponding duct (supply air duct or exhaust air duct).

In embodiments, the air flap can extend over at least 50% or at least 80% or at least 90% or possibly 100% of a cross-sectional area of the supply air duct and over at least 80% and/or over at least 50% or at least 80% or at least 90% or possibly 100% of a cross-sectional area of the exhaust air duct. When considering such an extension, any openings in the flap (for example between slats) should also be taken into account (as part of the respective “extension” or extension area in cross section). In particular, the air damper is considered in a (maximum) closed state in relation to the respective extension, in which case any remaining openings in relation to the extension are then not taken into account.

The air flap preferably extends over at least 100 cm ² or at least 500 cm ² or at least 1500 cm ² and/or at most 10,000 cm ² or at most 5,000 cm ² in a direction perpendicular to the flow directions of the supply air and exhaust air through the air flap.

The air flap preferably extends over at least 50 cm ² or at least 250 cm ² or at least 750 cm ² and/or at most 5,000 cm ² or at most 2,500 cm ² of a cross section of the air inlet duct when installed.

The air flap preferably extends over at least 50 cm ² or at least 250 cm ² or at least 750 cm ² and/or at most 5,000 cm ² or at most 2,500 cm ² of a cross section of the exhaust air duct when installed.

The (combined) air flap is preferably configured in order to close or open both air lines (that is to say the outside air-supply air line and the exhaust air-exhaust air line). In embodiments, the louver may be divided into two segments.

The air flap preferably forms an assembly, in particular a one-piece body (in which case individual parts of the one-piece body can be adjustable, for example optional slats can be pivoted and/or displaced). In particular, in the transition area of the air flap (when assembled) from the outdoor air duct to the exhaust air duct, sections of the air flap can also be monolithic, which can, for example, relate to a corresponding section of a frame (which extends from the area of the intake air duct to the area of the exhaust air duct).

The air flap is preferably at least predominantly made of metal, for example comprising at least 50% by weight or at least 90% by weight aluminum, but can also (at least in sections, if necessary completely) be made of plastic, in particular having appropriate thermal insulation. The thermal insulation can also be made from another thermally insulating material.

The air damper preferably covers at least in sections (possibly completely or at least 50% or at least 80%) both an outside air inlet, through which outside air flows into the air conditioning system (the air conditioning unit), and an exhaust air outlet, through which the air can escape from the air conditioning system (the air conditioning unit).

In embodiments, the air flap has a preferably rectangular and/or round frame. Alternatively or additionally, the air damper can have a multiplicity of (preferably rotatable and/or displaceable) slats.

A first group of slats is preferably arranged in the area of the supply air duct and a second group of slats is arranged in the area of the exhaust air duct.

The air flap can have a (preferably thermally insulated) central web which is preferably arranged between the exhaust air duct and the air intake duct. The central web can, for example, separate the first group from the second group of slats and/or have bearing devices for several or all slats. Here, above and below, a respective thermal insulation should preferably comprise at least 50% by weight of at least one material that has a thermal conductivity λ of less than 1.0 W/(m*K), preferably less than 0.5 W/(m*K), possibly less than 0.3 W/(m*K) at 20 °C.

A thermal separation can preferably also take place (partially or completely) by means of a stationary layer of air.

A central web can be formed from a plastic or from metal, for example aluminum, with a (thermally insulating) plastic layer. The plastic layer can, for example, comprise foam and/or be porous. Such a (thermally insulated) middle web can be used in a simple manner to prevent an undesired transfer of heat from the outside air area to the exhaust air area (or vice versa).

The air flap particularly preferably has a rectangular frame which is traversed (preferably at least approximately in the middle) by a central web. The middle web preferably connects the two longer sides of the rectangle and can be arranged or attached (or connected to the corresponding long side) in a respective middle third of the respective longer side.

The air flap and/or its frame and/or its central web can have a depth (ie in particular expansion in the direction of flow) of at least 2 cm or at least 5 cm and/or at most 40 cm or at most 25 cm.

The center bar is preferably perpendicular (at least substantially) to optional fins.

The slats according to the embodiment are preferably arranged parallel to a longitudinal side of the air damper, but can also be arranged, for example, at least essentially perpendicularly thereto. It is also conceivable that some slats are aligned parallel to the long side and some slats are aligned perpendicular to the long side.

At least 4 or at least 8 and/or at most 100 slats can be provided. The first and/or second group of lamellae can (each) have at least 2 or at least 4 and/or at most 50 lamellae.

A lamella of the first group of lamellas is preferably aligned with a lamella of the second group of lamellas. This can apply to several or all slats.

An adjusting device is preferably provided (possibly as part of the air conditioning system or the air conditioning unit, in particular as part of the air flap), which is designed to adjust the air flap with regard to a closed position of the same, in particular in such a way that the areas of the air flap assigned to the supply air duct and the areas of the air flap assigned to the exhaust air duct can be closed in a synchronized manner (in particular simultaneously), in particular by means of a common adjustment drive. Particularly preferably, the areas of the air flap assigned to the supply air duct and the areas of the air flap assigned to the exhaust air duct can be adjusted (e.g. closed and/or opened) exclusively together (in particular simultaneously), even if the respective areas have their own groups of slats.

Several, in particular all, slats can be coupled to one another, preferably positively coupled, via at least one coupling means, in particular comprising at least one gear wheel and/or at least one lever. As a result, it can be achieved in a simple manner that several, in particular all, slats can be adjusted in a synchronized manner (in particular simultaneously).

The ventilation and air conditioning system (the air conditioning unit) preferably has a housing in and/or on which the air flap is arranged. In concrete terms, the air damper can be arranged entirely within the housing, preferably in an edge section thereof.

The housing can have a separating device (e.g. dividing wall) for separating the air lines (that is to say the outside air supply line from the exhaust air line) which, for example, is aligned parallel to the air flow. One, two or more fluid delivery devices (e.g. fan(s)) can be arranged in the housing, for example one fluid delivery device (fan) in the supply air duct and one fluid delivery device (e.g. fan) in the exhaust air duct.

The above-mentioned object is also achieved in particular by an air flap for a ventilation and air conditioning system (an air conditioning unit), the air flap being preferably configured for the above ventilation and air conditioning system (the above air conditioning unit) and/or being a component thereof, the air flap having a preferably rectangular frame, a preferably thermally insulated central web which divides the air flap into a first area and a second area, and a large number of (preferably rotatable and/or displaceable) slats, with a first group of slats is arranged in the first area and a second group of slats in the second area. Further features of the air damper result from the above and/or following description of the air conditioning system (the air conditioning unit).

The air flap can include an adjusting device which is designed to adjust the air flap with regard to a closed position of the same, in particular such that the first and the second area can be closed (together) in a synchronized manner, in particular by means of a common adjustment drive of the air flap.

Several, in particular all, slats can be coupled to one another via at least one coupling means, in particular comprising at least one gear wheel and/or at least one lever.

The above-mentioned object is also achieved in particular by a building or part of a building comprising a ventilation and air-conditioning system (air conditioning unit) or air damper of the above type.

The above-mentioned object is also achieved in particular by using an air damper, preferably as described above, for at least partially closing off both a supply air duct and an exhaust air duct of a ventilation and air conditioning system (air conditioning unit), in particular of the above type.

In embodiments, the air flap can have a frame (in particular arranged and/or shaped rectangular). A thermally insulated center bar can divide the frame into two segments. Rotatably mounted and/or displaceably mounted lamellae can be arranged (installed) in these segments, distributed over the entire cross section.

The lamellae can (at least essentially) be formed at a 90° angle to the central web.

The slats of the segments can be connected via shafts passing through the central web, so that the slats of the two segments, which are preferably arranged in pairs in alignment, rotate at the same time.

Bearings for the slats can be arranged (installed) on two opposite sides of the frame and on the center bar. The individual slats can be connected to one another via gear wheels and/or levers on at least one or only one of the outer sides of the frame, so that the rows of slats can be rotated simultaneously.

An actuator can be mounted on one of the rows of slats for opening and/or closing.

The slats can be pivoted, for example, through an angle of at least 30° or at least 60°, preferably at least approximately 90° or possibly even more than 90°.

The air damper is preferably used in or on air conditioning systems (in particular an air conditioning unit). It should preferably be installed in such a way that one segment of the air damper fills the (complete) duct cross-section of the fresh air supply line and the other segment fills the (complete) duct cross-section of the extract air line. The two air flows can be separated by the central bar. Due to the interconnected slats of the two segments, both duct cross-sections can be closed with just one air damper and one actuator.

Overall, an outdoor supply air line and an adjacent exhaust air line of an air conditioning unit (air conditioning system) can preferably be closed with just one flap and one actuator.

Further embodiments emerge from the dependent claims.

• 2 eine schematische Schrägansicht einer erfindungsgemäßen Luftklappe.

The invention is described below using an exemplary embodiment, which is explained in more detail using the figures. Here show:

• 1 a ventilation system according to the invention (air conditioner) in a schematic sectional view; and
• 2 a schematic oblique view of an air damper according to the invention.

In the following description, the same reference numerals are used for the same parts and parts with the same effect.

1 shows a ventilation and air conditioning system (air conditioner) 10, comprising a housing 11, a supply air duct 12, an exhaust air duct 13. The channels 12, 13 are separated by a partition 14.

An optional fan 15 is arranged both in the supply air duct 12 and in the exhaust air duct 13 . A (common) air flap 18 is arranged at an outside air inlet 16 and an exhaust air outlet 17 . The air flap can also be located on the opposite side or in the middle of the device. This has an adjustment device (flap actuator) 19 to (in 1 not shown) slats of the air flap 18 to adjust. Arrows 20 indicate the outside air or supply air flow. Arrows 21 indicate the exhaust air or exhaust air flow.

An air damper 18 according to the invention is shown with further details in 2 to see. This can be found in Appendix 10 1 be built in, where in the in 1 specifically shown air damper, the adjusting device is arranged on the other side of the frame. However, this is not mandatory. Incidentally, the in 1 air damper shown may be formed as below with respect to 2 described.

Specifically, the air flap 18 according to 2 a first group 22 of slats 23 and a second group 24 of slats 23. The groups 22, 24 are separated by a central web 25 from one another.

Specifically, the slats 23 of the first group 22 are coupled to one another via gear wheels and/or levers 26 . So if the adjusting device 19 (comprising the flap actuator) swivels at least one slat, the other slats of the first group 22 are also swiveled. Since these are connected (in pairs) to the slats 23 of the second group 24, preferably via shafts passing through the central web 25, the slats 23 of the second group 24 are also coupled in that they are also adjusted when the first group 22 of the slats 23 is adjusted.

Specifically, one lamella 23 of the first group 22 is aligned with one lamella 23 of the second group 24.

The slat groups 22, 24 are supported (and held) by a frame 27 adjacent to the central web 25.

At this point it should be pointed out that all the parts or functions described above, seen on their own and in any combination, in particular the details shown in the drawings, are claimed to be essential to the invention. Modifications of this are familiar to those skilled in the art.

Furthermore, it is pointed out that the aim is to have as broad a scope of protection as possible. In this respect, the disclosure contained in the claims can also be made more precise by features that are described with further features (even without these further features necessarily having to be included). It is explicitly pointed out that round brackets and the term "in particular" are intended to emphasize the optionality of features in the respective context (what should not mean, by implication, that a feature is to be regarded as mandatory in the relevant context without such identification).
