Description

The invention relates to a method and a device for air conditioning of rooms, in particular for room air treatment.

In offices, practices, hotels, restaurants or similar work rooms, as well as in private rooms and houses with increased thermal insulation and limited air exchange between inside and outside there is an increasing demand for air conditioning facilities, since the existing or forming indoor climate often does not meet the needs. In many cases z. B. the humidity depending on the building design too low or too high, it is known that an optimum humidity should be 40-60% relative humidity to minimize the risk of unwanted microorganisms as well as the occurrence of specific disease symptoms (respiratory diseases, allergies) , Moreover, larger internal loads, caused by computers, printers, larger glass surfaces or increased load peaks of the outside temperature of more than 30 ° C contribute to the desire for a room air conditioning. This desire also arises from a generally higher need for comfort and greater health awareness, but also higher work demands in the workplace.

In new buildings, central air conditioning systems are often installed, but they are disadvantageous insofar as they do not sufficiently take into account the permanent spatial changes taking place during the use of the building (eg redesign of office space), as well as the personal requirements of the room users in the individual rooms , Moreover, these devices are preferably not designed for the supply of fresh air from open windows and appropriate central regulations take into account the individual needs insufficiently so that they often lead to acceptance problems.

Moreover, these plants are often inefficient in terms of energy with varying occupancies of the corresponding rooms due to vacancy, vacation or illness. Also retrofitting existing buildings for structural reasons with central air conditioning systems is often not possible.

Insofar as decentralized air conditioning systems (split units) are used, which serve in the actual sense of air cooling, they have only an insufficient effect on the conditioning of the room air overall, especially the humidification of the air and the air purity of the circulated room air volume flows. Also, the air distribution in the room is often inadequate, because in such decentralized air coolers, the air inlet and outlet structurally close to each other and is often placed wrong in the room.

Out DE 20 021 658 U1 is a device for cleaning and air conditioning using a plant reactor known as a biofilter, although only a portion of the intake room air over a rooted plant reactor with a volume flow rate of about 25% is filtered, while the other partial air flow with a Volume flow rate of about 75% at the cleaning (particle separation) and biological odor deposition does not participate, but is guided through heat exchanger for cooling and heating. Here, therefore, the vast majority of the room air flow must be cleaned with traditional filters and without a bioreactor.

From the GB 2 389 045 A For example, a room air conditioner is known in which air flows directly through a bioreactor that is moistened with a scrubbing liquid.

From the DE 42 09 570 C2 is a Raumklimatiseur known in which a temperature control of the flowing water as washing liquid is provided.

The invention is therefore an object of the invention to provide a method and a device for air conditioning of a room, the conditions for influencing the indoor climate in terms of performance (indoor air volume flow), cooling or heating of the room air, humidification or dehumidification and cleaning Room air of particulate solids or other, in particular gaseous components met.

This object is achieved according to the invention by the features of claim 1, in terms of the device by the features of claim 18.

Preferred embodiments are the subject of the dependent claims.

The solution according to the invention with the core aspects wet scrubbing of the room air and incorporation of a plant reactor, ie of plant green mass is used in an energetically highly efficient thereby apparatus technically surprisingly uncomplicated and the environment practically not burdening system on the one hand the well-known green mass (green plants) effectiveness for the detoxification of air pollutants which removes certain substances such as formaldehyde, nicotine, benzene or phenol from the room air and converts them into normal components of the plant biomass, while on the other hand, in a largely maintenance-free circulation system that from the wet scrubbing of the room air originating pollutants from the same loaded washing fluid (generally water) in turn as a nutrient solution to the plant reactor, ie the plant biomass can be supplied and contributes to their further growth or development and forms a nutrient source for the biomass.

Preferably, a hydroponic culture is used in conjunction with the plant reactor and the associated equipment is preferably mobile, e.g. B. mobile, Raumklimatiseur formed as a decentralized unit that allows a correspondingly variable installation in the room.

The invention combines functional principles of an air scrubber with advantages of a biological water purification such that a device for room air conditioning arises, which in a particularly advantageous manner all requirements for the conditioning of indoor air, d. H. Air purification, humidification or dehumidification, to ensure a preferred degree of relative humidity or a temperature control (cooling or heating) met.

Preferably, room air is sucked from one, in particular upper area of the room and the pressure side in a washing reactor, in particular bulk bed scrubber blown, in which an intensive heat and mass transfer between the room air and a washing fluid, especially water, takes place, depending on the temperature of the washing fluid also In this context, a cooling and humidification or dehumidification of the treated room air can be done.

The air purification is preferably carried out in such a way that noxious gases, in particular odorous substances, are dissolved on the washing fluid, in particular water drops, and on a moist substrate surface of a substrate, in particular particulate material containing washing reactor systems. Solid particles in the room air follow the acting flow and mass forces and adhere to the moist cleaning surface, in particular particle surface, of the washing reactor and are discharged with the washing fluid, in particular in a water circulation guided water flow.

Preferably, in the washing reactor from the room air in the fluid phase, in particular the water phase, the pollutant load is exchanged with the washing fluid, in particular the circulated water, pumped into the plant reactor and preferably dispersed there. The plant reactor is preferably a hydroponic culture in which the roots are in close interaction with the biomass and which absorbs the pollutants of the recirculated washing fluid supplied to the plant reactor (preferably the polluted water discharged to the scrubber reactor) as a nutrient solution in the biofilm of the hydroponic culture and over existing ones Bacterial cultures metabolized into green matter.

The room air conditioning device according to the invention is characterized by a predetermined air circulation in that the gaseous or solid (particulate) pollutants in the room air are transported in the washing reactor of the device in the preferably liquid washing fluid phase (in particular water phase) and in a locally separate plant reactor, preferably biodegrade to a green plant hydroponic system. The absorbed pollutants serve the green plant as food and are converted by this into green mass. Therefore, the room air conditioning and conditioning by the device according to the invention is extremely low maintenance, so that a filter change is eliminated and the pressure loss of the device is constant. In connection with the selected washing fluid temperatures, in particular circulated water, both a heating and a cooling, but in particular a moistening or dehumidifying of the room air take place, with regard to the temperature control and additional heating or cooling means already in connection with the room air flow, including may be provided independently or in addition to the room air wash.

The pipe fan 12 Incidentally, this is an extremely quiet suction or pressure fan with extremely low noise levels ("whispering fan"). In conjunction with the pipe fan 12 can also be a heater or cooling coil for preheating or pre-cooling of the intake room air connected.

A portion of the intake air is pressed into the plant reactor and supplies the plant area with oxygen and thus intensifies the biological conversion rate in the reactor. Incidentally, the sucked-in room air can also come from the pressure space of the room air supply module into the plant reactor 7 , Especially in the field of planter or overflow vessel for early room air cleaning in the root area of the preferably executed as a hydroponic plant arrangement 9 , preferably in a flow-controlled manner.

The preferably via a circulation pump 18 from the bottom of the water reactor 8th fed, resulting from the purification of the intake room air, polluted cleaning water is near the surface of the plant reactor 7 and thus the plant vessel 15 supplied and preferably in a uniform distribution, for. 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 this also serves as a nutrient solution, provided for the sterilization of the cleaning water.

In the plant reactor 7 is preferably also particulate material such as expanded clay and / or activated carbon and it comes in the washing reactor 8th to an intimate contact with that from the plant reactor 7 from the overflow vessel 16 exiting cleaning water with the polluted room air and to a laundry (cleaning of gaseous and solid particles) as well as to a humidification (or possibly dehumidification) or a temperature, preferably cooling, the room air.

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 both for wetting with the cleaning water from above as well as exposure to the incoming, 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 effluent, purified or generally conditioned in terms of humidity and temperature room air another temperature treatment, eg. B. be connected via a connected hot water system. Such an air heater is in 7 shown.

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 , for 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 taking into account disinfecting 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 the 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 connectable with a stationary washing fluid supply line, in particular with a water supply line provided by the customer, in order to track cleaning water into the washing cycle in a simple manner.

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. This ionization device is an optional possibility of room air pre-treatment, which - however, assuming a high voltage generator - can be omitted in other applications.

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 distributed cleaning water curtain. 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, on the other hand, but also 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.
