B. via a branched drainage tube, in the plant reactor 7 issued. Through the water-permeable bottom of the plant vessel, z. B. perforated plate bottom, the excess cleaning water enters the overflow vessel 16 in which the plant vessel 15 is included (cf. 4 and 5 ). In the overflow vessel 16 is a certain amount of water, eg. B. in the range of 10-15 l, to supply the through the bottom region of the plant vessel also penetrating fine roots of the green plant arrangement 9 the hydroponic recovered, wherein in the overflow vessel 16 can also settle suspended matter. Moreover, in this way, even with a temporary interruption of the water supply and irrigation of the root space by the overflow vessel 16 stored cleaning water the water supply of the plant arrangement 9 guaranteed. Moreover, the overflow vessel offers 16 the possibility of integrating a heat exchanger (heating or cooling coil, for example, a water cooler), the z. B. with appropriately tempered water or with a refrigerant can be operated so that the cleaning water before it enters the underlying washing reactor 8th at the same time as heat / cold transfer medium to the room air to be cleaned in the washing reactor 8th serves. The sectional view after 3 shows z. B. corresponding cooling register 9 that is either integrated in the overflow vessel 16 (not shown here) or separately located below it and from the overflow vessel 16 emerging cleaning water are applied (see also 1 ).

Preferably, in connection with the overflow vessel 16 also not shown here overflow nozzle 20 ( 2 ) connected when overfilling the overflow vessel 16 is effective and the cleaning water within the module unit 6 also in the underlying washing reactor 8th leads.

As 3 is clear in the room air supply module 5 Furthermore, in conjunction with the water cycle of serving to dissipate the pollutant load of the room air cleaning water, a UV filter 21 provided for the sterilization and reduction of biological Befrachtung preferably guided in circulation cleaning water, as well as possible connections for the above-described use of a temperature control (in particular water cooling) of the free in the washing reactor 8th from the plant reactor 7 entering cleaning water. The circulation pump 18 is preferably provided with a control and level relay and the UV filter 21 is preferably in the flow path of the circulation of the water reactor 8th led out polluted, polluted cleaning water in the plant reactor in which the ses also serves as a nutrient solution, provided for the sterilization of the cleaning water.

As 3 clarifies, points the overflow vessel 16 that's like the planter 15 preferably made of metal or plastic or a coated composite material, and the receptacle of the plant vessel 15 serves, lateral openings, in particular holes 22 on top of that from the plant box 15 leaving cleaning water on the outer wall of the overflow vessel 16 flows down and on an underlying liquid storage, z. B. a nonwoven mat 23 , drips, which in the manner of a sponge or water reservoir, preferably made of rot-proof, mottled needle felt in a thickness of about 10 mm. Due to the "wicking" of the fleece that will be from the overflow vessel 16 incoming water absorbed and inside the fleece mat 23 evenly distributed over its surface.

As the 4 clarifies, is this fleece mat 23 on a distributor floor 24 made of a wire or perforated plate structure, at least laid out of a liquid-permeable structure and are at saturation the cleaning water in the underlying water reactor 8th from.

Thus, the cleaning water drips homogeneously and distributed over the surface in the water reactor 8th and provides a uniform supply of water from above over an entire cross-sectional area thereof, wherein this cleaning water in contact with the transverse from the room air supply module 5 , in particular the pressure chamber 14 of the same incoming polluted room air enters.

Over the distributor floor 24 the cleaning water drips homogeneously and over the cross-sectional area of the washing reactor 8th distributed in these, the z. B. is filled with expanded clay and / or activated carbon particles so that the largest possible, flowed surface for both the wetting with the cleaning water from above as well as Beauf with the in-coming to be conditioned and polluted room air is available.

Preferably, the washing reactor 8th approximately a volume of 30 to 60 dm ³ and is on its opposite sides to the pressure chamber 14 the room air supply module 5 on the one hand and on the outside to the outside with opposite openings (see also 6 ), wherein an opening design takes place in such a way that a possible laminar air outlet of the cleaned room air takes place back into the surrounding space (air outlet openings 11 ).

For example, a plug-in grid is attached in front of the openings. To collect the contaminated cleaning water is how 2 clarifies, a floor 25 of the washing reactor 8th inclined towards the center and thus forms a water collecting space 26 , from which the polluted cleaning water in a circuit through the circulation pump 18 possibly also with the additional involvement of a heat exchanger for heating or cooling this polluted cleaning water fraction in 7 in a schematically illustrated manner in the plant reactor 7 is recycled in the manner described above. The internal piping of this return within the air-conditioning circuit 1 is in the schematic representation in 2 shown.

Possibly. can also be from the washing reactor 8th outgoing, purified or generally in terms of moist and temperature-conditioned room air another temperature treatment, eg. B. be connected via a connected hot water system. Such an air heater is in 7 With 27 designated.

For receiving the particulate fluid exchange material, such as expanded clay spheres and / or activated carbon particles within the washing reactor 8th , is in this a fluid-permeable, horizontal intermediate floor 28 , z. B. of perforated plate (see also 5 ), intended. Thanks to the inclined reactor bottom 25 collects at the lowest point of the water reactor 8th contaminated cleaning water and is through the circulation pump 18 to the plant reactor 7 pumped back inside the air conditioning course.

All units and receptacles, such as plant box 15 , Overflow vessel 16 , Distributor base 24 ie plant reactor 7 or washing reactor 8th are stored together with the room air supply module in a grid frame, in turn, the casters 2 carries, but here is not shown in detail (see 3 . 5 ).

Out 5 arises in connection with 4 again the vessel structure of the air conditioning module 6 , consisting of the removable planter 15 with a preferably perforated metal bottom, which in the overflow vessel 16 used and is included in this, whereas the overflow vessel 16 in the U-shaped profiled distribution floor 24 preferably made of perforated plate with the interposition of the nonwoven mat 23 is used, preferably using spacers 30 which causes a free dripping of the wall side from the overflow vessel 16 exiting cleaning water on the nonwoven mat 23 to care.

Preferably, the plant vessel 15 eyelets or inserts on two opposite sides near its upper edge 31 for handles on to the plant vessel 15 easy to remove from the lattice frame.

The embodiment realizes the essential aspect of the present invention, namely the merger of a cleaning water circuit with a room air circuit for conditioning or air conditioning of the room air, the special feature is that at the same time an integral inclusion of a biological room air purification takes place, on the one hand on the green mass of the used green plants arrangement 9 (Contact Room air green mass of the green plant arrangement 9 ), but further the polluted cleaning water at the same time as a nutrient solution for the green plant arrangement 9 is used, biologically-physically purified by these and the pollutants transferred by biological conversion into the metabolic cycle green mass of the green plant arrangement, whereby at the same time a closed cleaning cycle can be established, with all other conditioning effects such as heating or cooling of the purified air, humidification or dehumidification thereof due the wet scrubbing of polluted room air and other possibilities of direct air treatment by ionization (eg., upstream of the washing reactor 8th ) or a temperature control, z. B. by air heating of the purified room air (downstream of the washing reactor 8th ) as well as under consideration disinfection treatments in the cleaning water circuit by UV treatment or other elements. The cleaning water can also be selectively added biological and / or chemical agents that are harmless for the indoor air conditioning process on the one hand, but on the other hand, the biological growth process of green plant arrangement 9 in addition to the pollutant loading of the cleaning water serve.

It may be useful to the room air conditioner 1 in addition to make it also connectable with a stationary washing fluid supply line, in particular with a water supply line provided by the customer, in order to make it easier for him to feed cleaning water into the washing cycle.

The following is again the mode of action of the indoor air conditioning 1 explains:
This is characterized as a mobile and self-sufficient unit by at least one air conditioning module 6 from and a room air suction device, here a room air intake pipe 4 , from, where the air conditioning module 6 , preferably in a vertical arrangement, for the gravity feed of the cleaning water into the washing reactor 8th (but this is not mandatory, plant reactor 7 and washing reactor 8th could rather be arranged side by side using appropriate media flow control devices) vertically one above the other the plant reactor 7 and the washing reactor 8th having. The room air to be conditioned flows through the washing reactor 8th in cross-flow, with other flow conditions (equal or opposite flow) with appropriate spatial allocation of plant reactor 7 and washing reactor 8th possible are. Part of the polluted room air can also be in the plant reactor, especially in the root or fine root area, ie in the area of the overflow vessel 16 over z. B. a hose connection between the pressure chamber 14 the room air supply module 5 and the overflow vessel 16 for the ventilation of the plant space are introduced (eg with an air volume flow of about 50 m ³ / h), wherein preferably the entering into the plant vessel air is not introduced locally and selectively, but as uniformly as possible over the cross section of the whole vessel, with the goal of intensifying the biological conversion of pollutant load by supplying oxygen in the root area, in which case it also already directly in the plant reactor 7 and not only in the washing reactor 8th to a conditioning and cleaning and removal of solid or gaseous pollutants from the room air comes.

As 7 clarifies room air over preferably a coarse filter 13 by a fan arrangement, ie by a tube fan 12 sucked and preferably subjected to a pre-cleaning ionization treatment by electrical spray discharges.

These Ionisation device is an optional possibility of room air pretreatment, the one though High voltage generator presupposing - omitted in other applications can.

The sucked and polluted room air is then from the room air supply module 5 , in particular a pressure chamber 14 through a washing reactor filled with particulate material 8th passed in cross-flow and at the same time freed of pollutants in a finely divided Reinigungswasservorhang. Preferably, the polluted room air is also partially in the lower region of the plant reactor 7 led there, also there directly also by the existing there in the root area microstructure of the green plant arrangement 9 be cleaned in conjunction with the adjacent cleaning water, but on the other hand, for a uniform ventilation of the root area of the green plant arrangement 9 to care.

The pollutant-loaded cleaning water collected on the bottom side in the washing reactor is collected in the plant reactor, which is preferably designed as a plant hydroponic system 7 biodegraded, whereby the absorbed pollutants of the plant serve as food and are converted into green matter by plant metabolism. 7 illustrates the leadership of the cleaning water in a cycle with simultaneous, sterilizing UV treatment, the cleaning water can be passed through other heat exchangers, in particular a cooling device located in the area of the plant reactor 7 , preferably in the region of the overflow vessel 16 located. The purified air can optionally be further heated or after leaving the washing reactor 8th be cooled.

The invention thus provides a self-sufficient, energy-efficient and decentralized room air conditioning unit that realizes a biological-physical room air purification with high efficiency and can operate virtually maintenance-free over long periods of time. The from the room air-Klimatiseur 1 discharged, preferably discharged in laminar outflow, purified and conditioned room air can be made available in a pleasant temperature in the bottom area of the room, dust pollution by eddies and the like. Are avoided.
