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 ugly. For floor-to-ceiling windows, the one desired by the architect is design effect missed by the radiator standing in front of the window.

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. It has to be much more individual between radiation and Convection can be distinguished. The ones available on the market Air conditioning devices do not allow this development to react accordingly.

The invention has for its object an interior air conditioning device of the type mentioned at the outset, on the one hand, to improve integration allowed in 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 stand brackets are not visible as they 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 mixtures in the air conditioning device according to the invention as 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 areas that are difficult to access and difficult to clean, e.g. 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, e.g. Heat recovery is that of the invention underlying air conditioning device optimally equipped. Should rooms be / or are 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 device on which the invention is based can be solved by supplying fresh air directly via the building's outer facade via a fresh air duct through the rear wall into the outer wall built-in air conditioning device is initiated. In the air conditioning device can a silencer and / or a dust / pollen filter on this fresh air duct to be ordered.

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 only enter the radiant heat exchanger via a special valve until they are only fed 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 carried out 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 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. The front panel can handle 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 in sports facilities.
