A front plate (4) locks the opening on the front side of the enclosed case and supports the heat exchanger on its side turned away from the interior space. This front plate has a heat conducting area connecting to the heat exchanger to form a heat-radiating surface.

Description

The invention relates to an indoor air conditioning device in the Preamble of claim 1 mentioned type.

The integration of indoor air conditioning devices, for example Radiators, in walls and other parts of the building have so far not succeeded. Such devices are either like a foreign body under, in front of the window or in front of the wall. The pipe connections and pedestals are visible and unattractive. With floor-to-ceiling windows, the design effect desired by the architect becomes missed by the radiator standing in front of the window.

From DE 84 27 231 U1 a room air conditioning unit is known that one under a window sill with a built-in housing in a wall niche, a front panel has behind which a convection heater is arranged, through which with Air is circulated with the help of fans. This does make the aesthetic effect improved because the entire front surface of the niche through the front panel is covered, but the problem arises that to give off heat or cold Fans must be started that cause air flow and develop noises if necessary.

Radiators and other air conditioning devices work in front of the inner wall also unattractive and at the same time disturb the interior (furniture, curtains, etc.).

The thermal insulation regulations of the past few years have reduced energy consumption in the Building drastically reduced. At the same time, the type of heating / cooling has changed changed the room. There has to be much more individually between radiation and convection be distinguished. The air conditioning devices available on the market do not make it possible to react accordingly to this development.

From FR 27 76 757 A1 is an air conditioning device of the type mentioned Known type that both a radiant heat exchanger and a convection Contains heat exchangers, which are arranged one behind the other in the horizontal direction. Here, a control device is provided which in the heat exchange medium Distributed to the two heat exchangers depending on specified conditions.

The convection heat exchanger is also equipped with a fan here.

The invention has for its object an interior air conditioning device of the type mentioned at the outset, which on the one hand an improved integration in permits a building and on the other hand results in improved air conditioning.

This object is achieved by the features specified in claim 1.

Advantageous refinements and developments of the invention result from the Dependent claims.

The interior air conditioning device according to the invention can be completely in one Wall or part of another building component, for example a column. The visible wall panel is optically pleasing and does not disturb the interior, can behind curtains and furniture to be built in. The connecting pipes and pedestals are not visible because they are in the enclosure, preferably a prefabricated housing, are covered, the  arranged in a wall recess or recess or around a building Component is arranged around.

This creates living space. By installing the heating or cooling surface enlarged because the clearance surfaces of conventional radiators too Radiator niche in the air conditioning device according to the invention as a heating or Cooling surface can be used. The air conditioning device can thereby either get smaller or it becomes a lower cheaper temperature level of the heating or cooling medium selected.

The air conditioning device according to the invention also results in an improvement room hygiene and accident prevention, energy savings, an improvement of living comfort and simplification and cheaper installation. At the same time, the air conditioning device according to the invention additionally enables the fulfillment of a number of special tasks, which will be explained in more detail.

The air conditioning device installed flush with the plaster is no longer necessary the difficult to access and difficult to clean areas such. B. under and behind the conventional radiator. The dust particles from the room air that pass through circulate the air conditioner can be filtered out after the air intake become. A filter is not installed in all conventional radiators possible. This can promote hygiene and health.

The installation of this air conditioning device is therefore for hospitals and buildings suitable in which special emphasis is placed on air purity. Because the number of allergy sufferers ever increasing, a filter would also be appropriate in normal residential construction.

Accident prevention is an important issue in public buildings. Especially in Kindergartens, schools and sports facilities must be used for reasons of accident protection special radiators with rounded edges, sometimes behind the grille to be built in. The air conditioning device according to the invention has none in the Corners and edges protruding because it is preferably built into the wall.

The optimal heat or cold distribution in the room determines comfort. The conventional radiators give the heat in a certain, rigid ratio about radiation and convection. There is no cooling with this radiator possible. There are occasional climatic chests in hotels and administrative buildings. This  cool or heat the room with fans. It is bad adjustable, loud devices. Cooling via cold radiation is with the previously known facilities of this type not possible. In the case of the invention Air conditioning device can release both the heat and the cold Radiation or convection (with or without a fan) in a desired, individual adjustable ratio. With today's energy-saving design Frequently only a small amount of cooling is required, which is noiseless via the front panel Cold radiation is provided.

Also for modern forms of energy, such as B. Heat recovery is that of the invention underlying air conditioning device optimally equipped. Should rooms be and / or vented, the installation effort is very high in practice. In some cases, especially in residential construction for the new, promising "Controlled home ventilation" false ceilings and shafts are installed to to accommodate the channels and grilles. The problem of post-heating Room level is not really solved.

The room exhaust air can also be extracted in the area of the air conditioning device and the house exhaust system. By suction in the bottom up In the central area of the air conditioning device, additional energy is saved because the heat of the air in the upper part of the room is not extracted, but colder air from the lower layers of the air.

The room ventilation through the air conditioning device for the always This can result in "controlled living space ventilation" being used more frequently in residential construction take place that the partially heated fresh air via channels from below or laterally into the Air conditioning device initiated, heated to the desired room temperature and fed into the room. There are additional post-heating registers, outlet grilles and channel material saved.

Airtight soundproof windows are mandatory on busy roads. The Soundproofing problem can arise with the air conditioning system on which the invention is based device can be solved in that a fresh air supply directly through the building External facade via a fresh air duct through the rear wall of the into the outer wall built-in air conditioning device is initiated. In the air conditioning device can be a silencer and / or a dust on this fresh air duct / Pollen filter can be arranged.  

The cold radiation (winter) or warm radiation (summer) of a window or one The door is opened by the air conditioning device built into the wall next to it Heating or cooling (summer) compensated. This radiation compensation can be done with of the air conditioning device are most easily reached.

The heat or cold is from the previously known devices via radiation or Convection given. The radiation / convection ratio depends on the device type firmly. In the air conditioning device according to the invention, the ratio is Radiation / convection preferably adjustable from 0 to 100%.

The heating and cooling medium can be fed into the radiation via a special valve. Heat exchangers are only led into the convection heat exchanger. The Order of flow of the medium through the two heat exchangers can can also be controlled as required. The air conditioner becomes electric heated, the electrical heating energy can be the radiation heat exchanger or the convection heat exchanger can be switched on from 0-100%.

The heat or cold emission of the air conditioning device can be via a blower on the convection heat exchanger. The supplied to the room Radiant heat or cold can be increased if in addition to that Air conditioning device underfloor heating or cooling at one in the Air conditioning device located distributor is connected. The share of Heat or cold emission of the air conditioning device downstream Surface heating or cooling is also done via the above. Special valve controlled. The absolute heat or cold emission of the air conditioning device to the room via a thermostatic valve in the air conditioning device or a Room thermostats controlled.

The air conditioning device enables the room to be heated up quickly. Is the room is cold because the air conditioning device is longer for energy saving reasons Time was switched off or throttled, or after the room was ventilated the convection heat emission is automatically or manually also with the help of the fan can be increased significantly over a short period of time until the desired one is in the room Room temperature is reached.

The air conditioning device on which the invention is based enables a safe one and inexpensive assembly. The air conditioning device allows simple and  inexpensive connection options. At the same time, unsafe pipe connections are possible and couplings in the floor construction can be dispensed with, without the appearance the room shatters because all connection options in the housing of the Air conditioning device can take place. The lines from conventional Connection methods can be in the area of the floor construction below or from the Wall introduced laterally through recesses in the air conditioning device become. Lines for surface heating or cooling can also be installed at these points be discharged from the air conditioning device into the floor or into the wall. A new connection option, only by the invention Air conditioning device is possible, a vertical riser from floor to floor Floor, which is housed in the housing of the air conditioning device. There are no additional wall slots required for the riser. The heat losses of the vertical pipes get into the air conditioning device and come to the Space benefits.

The housing of the air conditioning device can be in the wall during the shell can be walled in or concreted. The pipe and sewer assembly is carried out later. First at the end, after completion of the construction work, the "actual Air conditioning device "installed as a radiation surface and convection part.

The air conditioning device is also well suited for individual special tasks. In rooms with little space - e.g. B. Front panels can be used in bathrooms, kitchens and toilets additionally with devices for hanging towels and drying be exploited. In a recess that is in the front panel below the center is located and serves to hold the toilet paper roll, exhaust air at the same time be sucked off. At this point is the smell and energy saving reasons best position for exhaust air extraction.

Even in small kitchens, the air conditioning device built into the wall is not Obstacle to kitchen furniture. The exhaust air extraction can also be in the area of lower air inlet grille.

Bathrooms, kitchens and toilets are also the "controlled ventilation system" Rooms in the apartment where air is extracted. In living rooms, bedrooms and children's rooms air can be supplied to the rooms via the air conditioning device.  

Since in the air conditioning device also electrical current for the operation of the Blower is needed, the installation of sockets for electricity, TV, EDP etc. in the front panel.

For particularly high stability while saving weight, the Heat exchangers are manufactured in sandwich construction. This embodiment is Particularly suitable for applications in robust everyday operation, such as B. in sports places.

The embodiment of the air conditioning device shown in FIGS. 1-3 is installed in a wall recess or wall recess and, in this embodiment, extends from the floor to the ceiling of a room, although of course the wall recess can also have a lower height. In this wall recess, an enclosure in the form of a housing of the air conditioning device is installed, each having thermally insulated upper, lower 1, lateral 9 and rear 10 housing walls. This housing 1 , 9 , 10 has a front opening directed towards the interior, which is essentially completely closed by a front plate 4 . On the side facing away from the interior, this front panel 4 carries a first Wärmetau shear 3 , which is thermally connected to the front panel 4 , so that the front panel 4 forms a radiation, heating or cooling surface. The first heat exchanger 3 can be flowed through in a controlled manner by a heat exchanger liquid.

Inside the housing 1 , 9 , 10 and at a distance from the first heat exchanger 3 , a second heat exchanger 5 can also be arranged, which forms a convection heat exchanger, in which case in the front plate 4 an upper air outlet grille 2 and a lower air inlet grille 6 is provided.

In the embodiment shown in FIG. 1, the air is supplied to the convection part via a lower air inlet grille 6 , behind which an air supply filter 13 can optionally be arranged, in order to prevent dust burns and other contaminations of the room air. The two grids 2 and 6 can also be detachably connected to the front panel 4 in order to facilitate assembly and revision.

As will be explained in more detail below, the supply air can also be supplied in a different way when using a convection heat exchanger 5 .

Both heat exchangers 3 , 5 can be acted upon in a controllable manner separately via lines 11 , 12 with a heat exchanger liquid, so that the proportion of the radiation heating or cooling or the convection heating or cooling can be set individually.

As already indicated in Fig. 2, the lower end of the housing 1 , 9 , 10 can be arranged sunk relative to the upper edge of the floor, wherein in the floor 7 itself air and heat exchange liquid channels can be laid, the openings 8 Ausneh in the lower area of the housing can be introduced into the housing 1 , 9 , 10 .

In Fig. 4 a detail of a further embodiment of the air conditioning device is shown, which differs from that shown in Figs. 1-3 in that the convection heat exchanger 5 is associated with a blower 14 . This fan 14 can be arranged below the convection heat exchanger and increase the air flow caused by pure convection and thus the heat or cold emission.

As indicated in FIG. 5, both the first heat exchanger 15 and the second heat exchanger 16 can be electrically heated when the air conditioning device is used exclusively for heating purposes.

As already indicated above with reference to FIG. 2, ventilation ducts and pipes can be introduced in the lower region of the housing 1 , 9 , 10 , the housing 1 , 9 , 10 being able to have correspondingly preassembled holders and connecting devices, so that the on-site Assembly is facilitated.

The two heat exchangers 3 and 5 or 15 and 16 , the front plate 4 and the housing 1 , 9 , 10 can be individual components in order to simplify the assembly. The two heat exchangers can also form an assembly unit ( FIG. 16). As can be seen in FIG. 6, the housing 1 , 9 , 10 has a ventilation duct inlet 17 in the area of the floor construction as well as further pipe inlets 18 , which lead pipes for any underfloor heating and / or the feed lines to the first and second heat exchangers can.

These pipe inlets 18 can also be seen in FIG. 7, which additionally shows a different type of supply of the supply air. In this embodiment, the housing 1 , 9 , 10 is in a wall recess in an outer wall or on the outer wall itself, and the outer wall also has an outside air duct 20 , which is protected on the outside of the housing 1 , 9 , 10 by a weather protection grid 19 is. In the interior of the housing 1 , 9 , 10 of the air conditioning device, this outside air duct 20 is connected to a muffler 21 or a fresh air / pollen filter 22 , in order to eliminate noise pollution on the one hand and to contaminate the outside air on the other hand.

When using a convection heat exchanger 5 in the interior of the housing 1 , 9 , 10 , a group of air baffles 23 can also be arranged in the area of the upper air outlet grille 2 and adjacent to it, which guide the air emerging from the convection heat exchanger 5 in the direction of the Deflect the air outlet grille 2 and out of it.

As already mentioned, the housing 1 , 9 , 10 of the air conditioning device can advantageously be used for receiving and connecting further components of an air conditioning system.

FIG. 9 shows an embodiment of the air-conditioning device, through the housings 1 , 9 , 10 of which vertical risers 24 extend, which are passed through the building corner 25 . The air conditioning device is then connected to these risers 24 via connecting pipes 26 , as is shown more clearly in FIG. 10.

FIG. 11 shows an embodiment of the front plate 4 of the air conditioning device. Since a fan must be supplied to the air-conditioning device in any case when using a blower in the air-conditioning device according to FIG. 4, it is obvious to arrange sockets 28 for current, antenna 27 or communication networks and the like in this front plate 4 at the same time. In this front plate 4 there is also a thermostatic valve that is directly accessible from the outside, although the heat exchangers can also be regulated centrally or by control devices hidden behind a front plate.

In Fig. 12, a special embodiment of the front panel 4 is shown when using the air conditioning device in a bathroom, which further design options of the front panel 4 reveals. This front plate has in addition to the air outlet and air inlet grilles 2 , 6 towel holder 32 and a recess 29 for a toilet paper roll 30 . In the area of this recess 29 for the toilet paper roll 30 , a suction shaft can be formed at the same time, which is provided via a line 31 with ventilation devices, not shown.

In Fig. 16 an embodiment of the air conditioning apparatus is further shown, in which the housing is omitted and instead a fixed wall in the recess wall frame 34 is replaced. In this case, the wall recess is in turn insulated, and the interior of the wall frame 34 is closed by the front plate 4 . As in the previous embodiments, this front plate 4 has air outlet and air inlet grilles 2 , 6 and a first radiant heat exchanger 3 on the rear side of the front plate 4 . However, this first heat exchanger 3 forms, with a second plate through which the heat exchange liquid flows, a convection heat exchanger element which interacts with the air outlet or air inlet grilles 2 , 6 , in which case a fan can of course also be provided in order to increase the convection effect. In this wall recess in the masonry 35 pipes and air ducts can of course be connected and routed as in the previous embodiments, but in this case the advantage of a preassembled housing with brackets and connecting pieces is eliminated, which means a greater effort during assembly at the construction site itself must become.

In the embodiments according to FIGS. 1-13 and 16, it was assumed that the air conditioning device is arranged in a wall recess or is arranged over a large area in front of a wall.

In Figs. 14 and 15, further embodiments of the air conditioning apparatus are shown in which a plurality of housings are designed for air conditioning apparatuses so that they present anyway in a building component, such. B. a square ( FIG. 14) or round ( FIG. 15) column 33 surrounded in cross section. In the embodiment according to FIG. 14, the housing of the air conditioning device has a substantially trapezoidal shape in horizontal cross section, so that it can surround the column 33 seamlessly when the front openings of the housing are closed by the front plate 40 .

In Fig. 15 the single housing of the air conditioning devices comprise the form of a circular ring segment and thus enclose the round column 33, wherein preferably also the front plates 41 have a rounded front surface. In this case, the first heat exchanger 3 , which is attached to the front plate 41 , is also curved. The convection heat exchanger 5 can have a usual straight-line shape due to its arrangement in the interior of the housing.

In the Fig. 17 shows a possible embodiment for a space-saving and extremely rugged design is illustrated of heat exchangers. The sandwich construction was chosen for reasons of better stability. At the same time, a relatively large beam and convection area is achieved with smaller overall dimensions.

Of the facing space to be conditioned radiation heat exchanger 46 consists of the front, optionally directly, the front panel 4 forming reflecting surface 42 a, a rear panel 42 b as well as between those arranged webs 43 that a space between the plates 42 and 42 b in Divide channels 44 and 45 for heat exchange media. The channel 44 can be used for heating or cooling liquid, the channel 45 for convection air. The convection heat exchanger 47 facing away from the room can be constructed in the same way and also forms channels 49 for heat exchange media and channels 48 for convection air.

In FIGS. 18-20 other possible embodiments of the webs 43 are shown between the heat exchanger plates.
