Description

The Innovation relates to an air conditioner housing after the preamble of the protection claim 1.

Air conditioner housings are used for ventilation and air conditioning applications and usually consist of large-volume housings with a volume of about ½ m ³ to 20 to 30 m ³ .

purpose Such air conditioner housing is the conditioning of the outside air sucked in by the environment with the purpose to filter this air, to clean it in another way, to be conditioned and if necessary also to cool or to heat. One of the external environment a housing sucked air flow is thus sucked into the interior of the air conditioner housing, there processed and in appropriately prepared form at the back wall of the housing discharged again and fed into appropriate ventilation ducts.

To For this purpose, it is known that the air conditioning housing substantially as a closed Form sheet metal box, wherein only on the front wall, the suction port and at the opposite Wall to arrange a discharge opening.

After this Such air conditioner housing in the Usually consist of sheet metal plates, existed in the prior art the problem that it is too unwanted Condensation phenomena came when a relatively cold airflow sucked into the interior of the air conditioner housing and the environment of the air conditioner housing with a common ambient temperature of 20 ° Celsius and Z. B. 80% relative humidity was surrounded.

It although it is known, such condensation phenomena in certain Dimensions too dominate, in which one trained as wall and ceiling coverings Walls of the Air conditioner housing as thermally insulated Forms sandwich metal sheets. This could solve the problem of prevention but not fully resolved by condensation phenomena, because in particular in the area of the edges of the housing limiting hollow sections Condensation phenomena occurred. These hollow sections were not thermally insulated, and put in undesirable Make a heat transfer from the relatively cold interior of the air conditioner housing to the warm environment this case ago.

Therefore formed in the area of these edge-side hollow profiles undesirable condensation phenomena.

Otherwise it is it is known in the art and is considered disadvantageous that the installation of such air conditioner housing is relatively complex, because many screw connections are used, which the Increase assembly time.

Another Disadvantage is that the connection between the walls of an air conditioner housing in Direction to the wall of an adjoining air conditioner housing only difficult to perform in the prior art. In the prior art were the connection connections between an air conditioner housing and the adjacent other air conditioner housing outside and were arranged therefore exposed to the aggressive ambient atmosphere.

Of the Innovation is therefore the object of an air conditioner housing the educate the aforementioned type so that with a simpler structure and faster assembly an absolutely thermally perfect decoupling between the relatively cold interior and a warm and humid outdoor environment guaranteed is.

to solution the task is the innovation by the technical teaching of claim 1.

essential Feature of the invention is that a thermal decoupling substantially by an insulating element takes place, which is in the form of a plastic hollow chamber profile on a thermally conductive, the Defining edges of the air conditioning unit housing Frame member is fixed as a metal hollow profile and in conjunction with an arranged on the inside of the housing T-shaped angle profile the stopper and attachment surfaces as adhesive surfaces for the formed trained trained wall elements.

The Innovation therefore relates to a profile system made of load-bearing hollow profiles, by a suitable selection of the materials used a high quality have thermal decoupling between inside and outside. This Profile system is used to construct housing elements for ventilation and air conditioning Equipment.

The Thermal decoupling takes place essentially through a plastic intermediate layer in the form of a hollow chamber profile (insulating profile), which together with the inner profile (angle profile) with the outer hollow profile of the housing frame force fit is connected. The inner profile can be made of different materials to be adapted to material-specific requirements and takes the static and dynamic loads in the housing element placed on installation parts.

The housing profiles are connected by a suitably shaped corner connector. The intermediate webs designed according to the same principle as the housing profiles for possibly. existing housing door (s) serve the stabilization of the housing element (Housing door) as well the practice-oriented division of the operating side of the air conditioner. These Intermediate webs are connected directly to the housing profiles.

With The given technical teaching thus results in the essential Advantage that a high load transmitting casing is realized that a per se thermally conductive hollow chamber profile is used from a steel sheet and this hollow chamber profile externally is arranged to form the edges of the air conditioner housing.

Around now a thermal decoupling between the thermally conductive hollow steel profile and the interior of the housing to ensure, is provided according to the new that an insulating profile on at least one side - and that on the air stream Side of the heat-conducting Steel hollow profiles - arranged is and that this insulating profile inside with an angle bar connected, which the stop surfaces and the adhesive surfaces for there to be connected thermally insulated trained wall elements forms.

In order to There is the significant advantage that any condensation phenomena on the outside the heat-conducting Hollow profiles are prevented because the thermally conductive hollow profile is with a Isolierprofil dressed at least on one side, wherein on this insulating profile - im heat-insulating Distance - one again heat-conducting angle bar is arranged, which in turn the adhesive surfaces for the wall elements to be connected there offers.

In order to results in a particularly simple installation, because it is sufficient with a single screw the heat-insulating insulating profile to connect with the steel hollow profile and with this screw connection At the same time, the angle bar arranged on the inside also becomes connected, which then the adhesive surfaces and stop surfaces for the there offers wall elements to be offered.

Of the possibly very cold interior of the air conditioner housing can therefore no Wärmeleitverbindung to that possibly warm outdoor environment of the air conditioner housing because the inside on the cold side arranged angle bar on a Screw or adhesive connection is connected to the insulating profile and in this area (on the cold side) also the adhesive joints for the Attachment of the wall elements are arranged on the angle bar.

On the warm side is therefore only the insulating profile arranged and the heat-conducting steel chamber hollow profile, which consequently no heat conduction to the cold interior of the air conditioner housing finds.

From particular advantage is the cheap thermal insulation the individual wall elements here it is in a preferred embodiment The innovation provided that each wall element of two at a distance arranged one another and parallel to each other sheet metal plates exists and the space between the metal plates with an insulating material filled out is. This insulating material may be formed as a foam or as a mineral fiber mat.

Important In this case, that in each case the inner and outer sheet forming wall part the respective wall element front side is not merged and there an unwanted one Forms heat conduction, but that there is a gap that is only through the end face of the insulating material is formed.

In order to becomes an undesirable Heat conduction of the inner panel on the outside bleaching prevents the respective wall element.

This Innovation is thus over Prejudice, in which a steel hollow profile as a high load transmitting Profile used and this however so thermally insulated from the cold Interior of the air conditioner housing trains, so that results in easy mounting a high-load-transmitting housing.

thermal Decoupling of the steel hollow profile in the direction of the cold interior is done over an insulating profile, which preferably forms with a plurality of hollow chambers is arranged in conjunction with an inside on the cold side Angled strip used to fix the thermally insulated wall elements serves and there on the cold side, the adhesive surfaces for fastening the wall elements formed.

Especially is advantageous if said angle bar formed as a T-profile is because the base T-leg the stop and adhesive surface for the connection of a wall element forms, while the T-leg of the same Opposite profile the adhesive and stop surface for the at an angle of 90 ° Wall element forms.

With the third leg portion of this T-profile then the angle bar is screwed to the thermally insulated insulating profile, glued or riveted.

in the The following is the innovation of only one execution way illustrative drawings closer explained. Here are more from the drawings and their description essential features and benefits of the innovation.

In 1 is generally an air conditioner housing 1 represented, which preferably consists of a rectangular body which consists of a front wall 2 exists, in whose area a suction port 3 is arranged, via which a to be conditioned air flow in the arrow direction 4 is sucked. The air flow, for example, has a temperature of -15 ° to -18 ° Celsius and is in the interior of the air conditioner housing 1 sucked in and conditioned there.

The rear, the front wall 2 opposite wall of the air conditioner housing 1 is therefore open and forms an outflow opening 5 , over which the conditioned air stream in the direction of arrow 6 flows.

It goes without saying that to the discharge opening 5 other similar or similar air conditioner housing 1 can connect, the connection areas are particularly easy and inexpensive to manufacture.

The air conditioner housing 1 also consists of a top wall 7 that has a bottom wall 8th opposite and also a back wall 9 , the one front operating wall 10 opposite. The operating wall 10 can be formed in total as a lid or a total of two doors 44 , which are in the range of hinge axes 43 swiveling on vertical edges of the air conditioning unit housing 1 are posted and on a vertically arranged gutter 11 strike sealingly.

Now it is important that the edges of the air conditioner housing 1 from high load transmitting hollow profiles 12 are formed, which preferably consist of a steel profile, which z. B. has a dimension and dimension of 44 × 45 mm and a wall thickness of about 1.5 mm. It is therefore designed as a high-load-transmitting rectangular tube and has - the air conditioning - but the disadvantage that it has a very good thermal conductivity.

object The present innovation is therefore condensation phenomena on this highly heat-conductive pipe to prevent.

For this purpose, a wall structure and a corner connection is used, as shown as detail II in 2 is shown in more detail.

First, it is noted that all hollow sections 12 through corner connectors 13 are connected together and this corner connector is in 9 shown in more detail.

The thermal insulation of the highly conductive hollow profile 12 takes place thereby, at least on the one side of the hollow profile 12 a high heat insulating insulating profile 25 is screwed, in which case the screw 52 is used. Details of the insulating profile 25 arise from the 3 and 4 ,

It is important that on the insulating profile 25 now the front of the back wall 9 abuts. Every wall 7 - 10 consists of an inner sheet 20 and an outer panel 21 , with the gap between the two sheets 20 . 21 through an insulating material 19 is filled.

In order to prevent unwanted heat transfer from the outer panel to the inner panel are the forehead leg of the sheets 20 . 21 guided to the inside and there interrupted the front side, so that there is a gap 23 results in which only the front side 24 of the insulating material 19 appears in appearance. This prevents unwanted heat transfer from the inner panel to the outer panel.

Incidentally, this interruption applies to all wall elements 7 - 10 ,

It is also important that the inside of the insulating profile 25 and in the distance to the installation room 14 which is relatively warm, an angle bar 27 with the same screw connection 52 on the insulating profile 25 is screwed on. The angle bar 27 is in 5 shown in more detail and it will be discussed later on this presentation.

In the interior 15 of the air conditioner housing 1 Thus, relatively low temperatures in the range of -10 ° to -20 ° Celsius at low relative humidity, while in the installation room 14 a relatively higher temperature at higher relative humidity exists.

The angle bar 27 forms with its stop bar 34 an adhesive surface 51 for fixing the rear wall 9 on this angle bar 27 , Furthermore, forms the support bar 35 the angle bar 27 again an adhesive surface 50 for fixing the bottom wall 8th ,

Moreover, it is not necessary in the area of the front side of the bottom wall 8th in the direction of the hollow profile 12 another insulating profile 25 to install, because the bottom wall 8th and the hollow profile 12 in this area a floor area 53 form and thus on a Aufstellbene 54 rest, which is not flown by air. For this reason, there need not necessarily be another insulating profile attached.

However, it is within the scope of the present innovation, also in this area an insulating profile 25 to arrange.

To a high-load-transmitting connection of a guide rail 16 on the hollow profile 12 to enable, is the said angle bar 27 used and trained as L-profile guide rail 16 is thus on a support bar 35 the angle bar 27 on. On the thigh 17 this guide rail 16 are then the ventilation equipment and devices that can have a high weight up to 1 ton. The vertical leg 18 the L-profile serves as a guide rail.

The angle bar 27 is preferably flush with the surface of the insulating profile 25 connected. For this reason, beats the front of the angle bar 27 at an associated stop 26 of the insulating profile 25 at.

The insulating profile 25 exists according to the 3 and 4 from a hollow plastic profile with a number of hollow chambers 28 that are air-filled. Instead of the air filling of the hollow chambers 28 they can also be foamed.

The material of the insulating profile 25 is preferably a rigid PVC, which is UV-resistant and has a material thickness of about 2 to 3 mm. It is achieved a cross-sectional area of 280 mm ² .

It is important now that in the area of the bearing surface 29 for mounting the angle bar 27 an air-tight sealing lip 30 in the material of the insulating profile 25 is formed. For this purpose, the sealing lip 30 in a recess below the support surface 29 arranged and this sealing lip 30 is springy and obliquely upwards. As soon as the angle bar 27 with their attachment legs 36 on the support surface 29 is applied, the sealing lip 30 bent downwards resiliently and placed in a tight and sealing against the underside of the mounting leg 36 the angle bar 27 at.

This will create an unwanted passage of air from the warm room 14 in the cold interior 15 of the air conditioner housing 1 prevented.

In addition, in this area the front side of the rear wall 9 and the top of the insulating profile 25 on the outside a sealant 32 be arranged. This is also an overflow at the top of the angle bar 27 prevented with an undesirable air flow.

It is still added that the sealing lip 30 in the direction of the arrow 31 and is formed resiliently in the opposite direction.

The 3 shows, moreover, that the insulating profile 25 lateral arcuate approaches 33 which adjoins the arcuate edges of the hollow profile 12 nestling and sealing there. There are thus created sealing surfaces which an air-tight seal between the insulating and the associated walls of the hollow profile 12 enable.

In 5 is shown that in the area of the attachment leg 36 the angle bar 27 a hole 37 is arranged through which passes through a screw not shown, which at the same time the angle bar 27 with the insulating profile 25 on top of the hollow section 12 anschraubt. This creates a high-load-carrying, very simple connection that is easy to assemble.

In 1 is still shown that the control wall 10 as a two-leaved door 47 may be formed and - if this is the case - this is a heat-insulating gutter 11 used as he said on the basis of 6 will be described in more detail below.

The thermally insulating trained Zwi rule footbridge 11 consists of a stop plate 38 , which for screw fastening to the hollow profile 12 suitable is. The screw fastening is in 6 not shown in detail.

It is important now that with the stop plate 38 an insulating profile 40 is connected, which in turn is a thermal insulation in the direction of the hollow profile fixed there 41 formed. The hollow profile 41 is again a steel hollow chamber profile, which is high-load transmitting.

The hollow profile 41 proposes according to 7 and 8th at associated sealing surfaces 47 of the insulating profile 40 on, the several air-filled hollow chambers 28 formed. They are approaches 45 available, which stops for the pages to be created there of the hollow profile 41 form. The sealing approaches 46 are approximately arcuate according to 8th executed and thus lie sealingly and airtight on the outer sides of the hollow profile 41 at.

The stop plate 38 is with a screw fastening 39 with the insulating profile 40 connected, with the screw fastening 39 also in the hollow profile 41 intervenes.

To the inner stop surfaces 42 the support bar 38 then hit the doors 44 the operating wall 10 at.

In 9 is a corner connector 13 shown how he to the corner joint at an angle of 90 ° colliding hollow sections 12 suitable is. It is preferably made of a plastic or a metal body 49 , at the three plug approaches 48 are arranged at an angle of 90 °. The plug-in approaches 48 engage in the interior of the hollow profile 12 one. The connection area between the sockets 48 and the interior of the hollow profile 12 can be arranged heat-insulating intermediate layers.

At the back is the body 49 closed by appropriate cover.
