Description

Technical description.

Technical field.

The invention relates to a device for guiding the supply air and exhaust air of the condenser of a monoblock air conditioner attached to the inside of an outer wall.

State of the art.

An air conditioner is used, among other things, to cool the room temperature.

• Splitanlage mit außeninstaliertem Kondensator und einem oder mehreren inneninstallierten Verdampfern. Der außen-installierter Kondensator ist gewöhnlich fest an der Haus-Außenwand installiert. Die Außen-Installation leistungsstarker Kondensatoren solcher Splitanlagen ist häufig aus Gründen des Lärmschutzes, Denkmalschutzes, behördlicher Auflagen oder fehlender Einwilligung des Immobilieneigentümers / Vermieters nicht umsetzbar.

Different types of air conditioners are known:

• Split system with externally installed condenser and one or more internally installed evaporators. The externally installed condenser is usually permanently installed on the outside wall of the house. The external installation of powerful capacitors of such split systems is often not feasible for reasons of noise protection, monument protection, official requirements or the lack of consent from the property owner / lessor.

Free-standing air conditioning unit monoblock in the room to be cooled, with integrated condenser and evaporator. Supply air is extracted from the room air and warm exhaust air is usually discharged to the outside through a loose hose through an open window. Floor units of this type are less effective than split systems. The exhaust air routing via a window-guided exhaust air hose also reduces the cooling effect due to the inflowing warm outside air. The alternative supply and exhaust air routing through wall drilling requires the consent of the property owner.

Air conditioning unit monoblock fixed to the interior wall, with integrated condenser and evaporator, as published in EP 1116001B1 , Modern internally installed air conditioning unit monoblocks are flat, similarly powerful as conventional split units and also quieter in operation than conventional split units. Due to the flat, weight-saving and aesthetic design, such air conditioner monoblocks are increasingly being installed. Supply air from the condenser is supplied from the outside of the room and the exhaust air from the condenser is discharged to the outside. According to the current state of the art, the supply air and exhaust air routing of the condenser are restricted to outside wall bores. However, this technical implementation is usually not feasible due to the lack of consent from the property owners, especially in rental apartments in metropolitan areas. There are no alternative technical solutions for the supply and exhaust air routing of the condenser to avoid structural changes requiring approval (wall drilling).

Object of the invention.

The invention has for its object to provide an improved device for the supply and exhaust air routing of the condenser of a wall-mounted air conditioner monoblock without a structural change.

The invention is based on the further object of providing an improved device for supplying and extracting air from the condenser of a wall-mounted air conditioning unit monoblock, which runs without wall bores.

The invention is also based on the object of providing an improved device for supplying and extracting air from the condenser of a wall-mounted air conditioning unit monoblock so that the air conditioning unit can be started up inexpensively and in self-assembly.

The invention is based on the additional object of providing an improved device for supplying and extracting air from the condenser of a wall-mounted air conditioning unit monoblock, which can be dismantled and reassembled together with the air conditioning unit monoblock at another suitable location.

The invention is also based on the object of providing an improved device for supplying and extracting air from the condenser of a wall-mounted air conditioning unit monoblock, which the operator himself can replace after wear or repair.

The invention solves these problems according to the marked part of protection claim 1 in that an air duct adapter device is installed between the condenser of a wall-mounted air conditioner monoblock and an existing tiltable component with an external opening. As a result, the supply and exhaust air circulation of the condenser takes place via an existing tiltable component, such as a tilting window or tilting door, without any structural measures being necessary. The subclaims indicate advantageous design options for the air duct adapter device.

In technical terms, the term "tiltable component" includes tilting doors, tilting windows, tilting gates and tilting flaps in the roof, living room, work area, kitchen, sanitary area and basement of buildings, as well as in garages, halls and buildings in general. The term "tiltable component with external opening" chosen for the present invention clarifies the transition (space gap) from the interior of the room to the exterior, via the tiltable component.

Wall-mounted air conditioner monoblocks are often installed above windows such as bottom hung windows. The air lines to the supply air and exhaust air connections of the condenser are located in horizontal wall holes to the outside.

An air duct adapter device according to the invention ( 6 ) between supply air ( 4 ) and exhaust ( 5 ) Connections of the capacitor ( 1.2 ) and the top opening of a tilt window, as in the 5 and 7 shown.

1 describes the elements and the installation steps A and B the particularly advantageous two-part air duct adapter device ( 6 ), consisting of an air duct ( 21 or 22 ) and an adapter element ( 23 ) with gap seal ( 17 ). The air duct for guiding the supply air ( 21 ) and the air duct to guide the exhaust air ( 22 ) are made of a U-shaped, elastic, tear-resistant and temperature-resistant material (air duct material) in a suitable thickness. The air duct for guiding the supply air ( 21 ) encloses in step A with its U-shaped bend the supply air connection ( 4 ) of the monoblock capacitor ( 1.2 ). Similarly, the air duct encloses the exhaust air ( 22 ) with its U-shaped bend the exhaust air connection ( 5 ) of the monoblock capacitor ( 1.2 ). 4 shows how the free ends of the U-shaped air duct for supply air ( 21 ) and for exhaust air ( 22 ) in one area ( Z ) ends, which is limited by the position of the lower edge of the monoblock air conditioning unit and which is limited by the position of the underside of the lintel ( 12 ). The free ends are in crotch B the 1 into the transducers ( 25 ) an adapter ( 23 ) for the supply air duct or the exhaust air duct, so that an airtight seal is created. A sealing lip ( 27 ) additionally seals in the area of the transition from the rear of the air conditioner to the underside of the air conditioner ( 4 . 5 ). 2 shows the air duct adapter device ( 6 ) after completing the steps A and B , Both adapters ( 23 ), for the supply air duct ( 21 ) and the exhaust air duct ( 22 ) are in their air duct opening ( 16 ) - directed half in an elastic adapter gap seal ( 17 ) embedded ( 2 ).

The air ducts for supply air ( 21 ) and for exhaust air ( 22 ) are fitted precisely between the monoblock rear wall and the inside of a room outside wall, so that there is an airtight seal between the monoblock rear wall and the room wall, as in the 4 to 7 shown. By means of the elastic adapter gap seal ( 17 ) the window gap is sealed airtight.

The use of the supply and exhaust air adapter according to the invention is not limited to tilting windows. Rather, the adapter can be used on all tiltable components with an external opening known to the person skilled in the art.

The air duct adapter device according to the invention ( 6 ) is designed as a two-part device, as in 1 . 2 and 4 - 7 shown. The air duct adapter device according to the invention ( 8th ) is designed as a one-part or multi-part device in embodiments that are not shown.

In a further embodiment of the adapter according to the invention ( 23 ) are the sensors ( 25 ) of the adapter with air duct material ( 26 ), see 6 and 7 , The 6 and 7 also show that the free ends of the air ducts do not protrude into area Z, they close with the underside of the air conditioner. When connecting an adapter ( 23 ) to a supply air duct ( 21 ) or exhaust duct ( 22 ) when attaching the adapter via the brackets 28 and 29 that in the transducers ( 23 ) located air duct material ( 26 ) pressed against the free ends of the air ducts, and an airtight seal occurs ( 7 ). A sealing lip ( 27 ) additionally closes the connection in the area of the transition from the rear of the air conditioner to the underside of the air conditioner.

1 and 2 show examples in the adapter ( 23 ) horizontal air duct opening for the supply air ( 16.1 ), and the air duct opening for the warm exhaust air ( 16.2 ). The width of the air duct openings is based on the optimal air circulation for operating a wall-mounted air conditioning unit monoblock and can vary depending on the model. In embodiments that are not shown, the air duct openings ( 16.1 . 16.2 ) almost over the entire width and height of the adapter gap seal ( 17 ).
The airtight insulation of the side area of a tilting window does not fall within the scope of the present invention. Suitable foam blocks or elastic, inflatable air barriers in the form of a window side gap are conceivable for insulation. Insulation with foldable elements, as in EP2199525 A2 described, possible.

The advantages of the supply and exhaust air adapter according to the invention are the avoidance of construction measures requiring supply and exhaust air for the condenser, which are subject to approval, and the simple installation between the air conditioner and an existing tiltable component with an external opening.

The device according to the invention has been described above using some exemplary embodiments. It goes without saying that numerous changes and modifications are possible, especially with regard to the material nature and design of the adapter ( 23 ) and its localization on the wall-mounted air conditioning unit monoblock, without thereby leaving the inventive concept on which this device is based.
