Marine Climate Air Conditioning Units

technical field

The invention relates to a marine climate air conditioning device having a fan for generating an air flow, a humidifying device for humidifying the air flow with mineralized, in particular sea salt-containing water, and a UV light source.

Background technique

For example, DE 3518456 A1 discloses a marine climate air-conditioning device of this type. Air conditioners, which are called therapeutic air conditioners therein, have as humidification means a spray device for generating mist from sea water and a blower for generating an air flow which passes through the mist and carries it into the exterior space. Furthermore, a UV light source is provided, which is arranged in the region of the air inlet and irradiates both the room air sucked in by the blower and the seawater in the tank for fogging with UV light. In this way, it is desired to generate an indoor climate corresponding to the conditions in the area of sea waves, wherein in particular it is also desired to simulate all influences of the solar spectrum in the entire UV range.

Air conditioners have different technical deficiencies on the one hand. The spraying of salty water by means of the spraying device therefore also leads to salt deposits inside the air conditioner, in particular on the spray nozzles themselves, which can impair the functionality of the air conditioner within a short time. Furthermore, the salt spray can attack and damage metallic and especially electrical components of the air conditioner, such as fans and UV light sources, due to corrosive effects. In addition to these technical disadvantages, air conditioners on the other hand show only limited efficacy in terms of health-friendly influence and improvement of comfort through the indoor climate created by the air conditioner.

Furthermore, various other therapeutic air conditioners and air humidifiers are known. For example, DE 10054562 A1 discloses a therapeutic air conditioning device in which an air flow generated by means of a blower is guided through a curtain formed of water droplets and thus humidified. In addition, there is a UV light source for irradiating the water in the tank in order to kill microorganisms that may be present in the water.

DE 10 253 842 A1 discloses a therapeutic air conditioning device in which the air flow is humidified, for example by means of a water-impregnated non-woven fabric through which the air flow flows. Here too, a UV light source is provided which is arranged above the water storage container and illuminates the water surface in order to kill germs or bacteria which may be contained in the water. Furthermore, an ionization device is described, which is to be arranged in such a way that the ions emitted by the ionization device are fed into the air flow.

A therapeutic air-conditioning device is disclosed in DE 440 497, in which the sucked-in external air is guided through a curtain of droplets formed from a liquid. The UV radiation from the UV light source also acts on the liquid in the container. Furthermore, a structural modification of the liquid or of the droplets is to be effected by means of low-frequency electromagnetic signals, which is to advantageously influence the therapeutic climatic air.

Finally, US Pat. No. 4,686,069 discloses an air humidifier in which the air flow is humidified by means of a gas-permeable medium, such as a porous sponge, for example, located between two high-voltage electrodes. The porous sponge dips with its lower end into a water-filled trough and thus absorbs enough water due to capillary forces, which is expelled into the air flow. This configuration is not suitable for working with saline water, since the sponge will quickly become salinized due to atomization on the surface of the sponge.

Contents of the invention

It is therefore the object of the present invention to provide a marine climate air-conditioning device which is improved with regard to the effectiveness of the generated room climate, in particular enabling conditions which are significantly closer to a real marine climate. Furthermore, the invention presents various technical improvements which make the marine climate air-conditioning device significantly different from conventional air-conditioners in terms of reliability, vulnerability, lifespan, operating noise and in terms of manufacturing costs.

Here, the invention is primarily based on an in-depth understanding of the factors influencing the marine climate and the physico-chemical processes associated therewith.

This object is achieved by the features of claim 1 . Advantageous refinements are to be found in the subclaims.

For such an air-conditioning unit for marine climates, the object is achieved in that the humidification unit can be passed through by the air flow and is arranged in the flow direction; a simulated climate chamber is provided adjacent to the humidification unit and arranged after the humidification unit in the flow direction The UV light source is arranged such that the UV light source irradiates with UV light the humidified air flow flowing through the simulated climate chamber and the humidification device surface facing the simulated climate chamber through which the air flows.

The teaching according to the invention is based here in particular on the knowledge that the action of UV radiation on the humidified and mineralized air flow leads to an in particular physico-chemical activation of the molecules and groups of molecules contained therein. At the same time, the energy-laden UV radiation that has acted on the surfaces of the humidifying device leads to a breakdown of the water- and salt particles, converting them into highly soluble fractions, which are more easily output to the air stream. The different physico-chemical processes resulting from the dissolution lead to an activation that mimics sea waves, which can already be determined in the room air after a short time in terms of odor and taste during the operation of the air conditioner.

Importantly, to the knowledge of the inventors, e.g. the effect of UV radiation and microbial efficacy not only on flowing or stationary water volumes, but also on humidified and mineralized air streams and interfaces wetted by saline, in Water molecules and minerals at the interface are exported to the air stream.

Furthermore, the efficiency of the marine climate conditioning device can be further increased when an ionization device is provided for ionizing the molecules contained in the air flow. It is important here that the ionization device also acts in part on the humidified air flow flowing through the climatic chamber, also in the climatic chamber. Such an ionization device, which can be achieved, for example, by an arc discharge of a high-voltage discharge cell preloaded with about 10 kV, simulates a state (as occurs in sea waves and spray due to triboelectricity) and leads to charge transfer and air Ionization of chemical groups and molecules - or groups of atoms - in a stream.

According to another particularly advantageous aspect of the invention, the humidification device comprises a salt bath unit which is overflowed and/or passed through vertically by the mineralized water and horizontally by the air flow. This salt bath unit is composed of a plurality of microstructures, which approximately form a flow-conducting support, which is covered with a tiny liquid film by the brine flowing through the salt bath unit and on the one hand provides for the export of minerals and water molecules. A large surface is formed to the air flow, while on the other hand only a small flow resistance is formed for the air flow due to its porosity. This salt bath unit thus represents a simulation and miniaturization of the salt bath dripping devices currently found in different health resorts, in which salt water is guided through tree branches (Reissig), which are in large in the form of bundles stacked as wooden supports.

In addition to the large surface area, it is achieved in this salt bath unit, based on a continuous liquid flow through the salt bath unit in the vertical direction, without the formation of salt deposits and crusts, which would interfere with the air passage As well as preventing the transfer of moisture to the air flow. Furthermore, in contrast to jet atomizers, it is avoided that brine and salt deposits reach metallic or electrical components, seals, etc. and cause corrosion and material damage there.

Preferably, the salt bath unit is made of UV and salt water resistant material. Within the framework of the present invention, polyester is preferably used as material for the salt bath unit, which is at least partially made of polyester.

In a particularly easy to implement embodiment, a salt bath mesh is used as the salt bath unit, the salt bath mesh being made of a non-absorbent material. Such a salt bath net should also in particular not have a capillary effect and thus not store water, since this reduces the air permeability on the one hand and on the other hand causes damage to the salt bath net due to the amount of water stored.

Within the framework of the present invention, the material of the salt bath net is particularly preferably a porous filter foam, for example based on polyester or polyurethane. In order to achieve good air permeability, the filter foam should have a pore size of at least 0.5 to 2.5 mm. The plastics content of the filter foam should be below 8% by volume, preferably 2-4% by volume, most preferably approximately 3% by volume. In such filter foams, pore size is usually determined in units of pores per inch (ppi). Within the framework of the invention, preferred pore sizes are from 10 to 30 ppi, preferably on average about 20 ppi.

Alternatively, the salt bath unit can also consist of microstructured entanglements, fabrics or braids, such as polyester fibres, wherein the above statements regarding the volume fraction also apply here.

The salt bath unit or the salt bath net is preferably designed as an exchangeable part which can be easily removed from a corresponding holder of the air conditioner and replaced by a new unit. If a salt bath unit is impaired in its functionality by foreign bodies that have entered—like dust—or by salt crusts, it can be easily removed and either replaced by a new unit or cleaned and used again. The support can here be designed, for example, in the form of a plug-in drawer into which the salt bath unit is inserted together with the holding frame.

During operation of the salt bath unit according to the invention, a relative air humidity of <100%, preferably <80%, occurs in the simulated climate chamber relative to the sprayer, so that no precipitation occurs in the housing and especially outside the air conditioner Precipitation also does not occur before its air outlet.

In a preferred embodiment of the air-conditioning device for marine climates according to the invention, the lower region of the air-conditioning unit is designed as a tank, which serves as a container for mineralized water and is likewise irradiated with UV light by the UV radiation source. On the one hand, the microbiological efficacy of UV light is thus utilized in a known manner in order to maintain the sterility of the brine located in the tank, and on the other hand, the water flowing through the salt bath unit then drips back into the tank designed as a container, thus ensuring continuous circulation of water.

The marine climate-conditioning device preferably has a pump which conveys the mineralized water from the container to the upper region of the salt bath unit, from which the mineralized water overflows and/or flows through the salt bath unit. In this case, preferably a distribution channel can be provided above the salt bath unit, via which distribution channel the water is distributed substantially uniformly over the width of the salt bath unit and delivered to the salt bath unit. In this case, the pump only needs to convey the mineralized water from the container to the distribution channel, so that only low technical requirements for pump performance and delivery volume are required, ie the pump can be constructed correspondingly simply and inexpensively.

The pump can here be arranged both in the form of a submersible pump in the water tank or also in the form of a suction pump above the water tank and preferably above the salt bath unit. The delivery capacity of the pump is preferably in the range between 50 and 300 l/h.

According to the inventive concept, the UV light source is preferably arranged in or above the climate chamber, so that the UV radiation emitted by the UV radiation source is mainly effective in the climate chamber and on the surfaces of the humidification device facing the climate chamber. The radiation power of the UV light source or the light intensity incident by the UV light source in the active region of the simulated climate chamber is preferably in the range of 10 and 20 mW/cm ² , most preferably about 15 mW/cm ² .

Unlike most known air conditioners, where an attempt is made to generate as strong an air flow as possible in order to be able to circulate as much room air as possible, the present invention recognizes that the very slight ventilation through the air conditioner has already It is sufficient to achieve the effect according to the present invention. Air exchange in a room to be climate-conditioned is not, for example, by convection, ie a mass air flow, but rather a diffusion process for concentration balance based on Gay-Lussac's law or Fick's diffusion theorem.

In order to be able to carry out the diffusion process as unhindered as possible, in the marine climate air-conditioning device according to the invention, the fan, the humidifier and the simulated climate chamber are arranged in such a way that the air flow passes through the marine climate in a substantially straight line from the air inlet to the air outlet. air conditioning unit. In particular, in the air conditioner according to the invention it is ensured that the air flow is not flow-guided by means of ventilation ducts, guide surfaces and deflecting surfaces.

Since, according to the inventive knowledge, a very weak air flow with a small flow velocity and a small volume flow is sufficient to achieve the effect according to the invention, the fan can be correspondingly small in size and run slowly and continuously, thereby reducing the Small intrusive fan noise. In particular, compact and low-noise operating fans can be used, as they are for example in computer housings. In order to minimize the fan housing, it is possible in particular to use so-called bionic fans, ie fans with a bionic-optimized rotor design. The fan is preferably dimensioned and operated such that the fan circulates in the range of 20 to 80 m ³ /h, especially preferably in the range of 30 to 60 m ³ /h and most preferably in the range of 40 to 50 m ³ /h air volume and move the air volume through the simulated climate chamber.

According to the inventive concept, it is especially preferred to generate an air flow by means of a fan which flows through the salt bath unit essentially in layers. This is achieved by a correspondingly low flow velocity and a correspondingly high air permeability of the salt bath unit.

Proving to be particularly effective in participating in the physico-chemical processes generating the marine climate is UV radiation in the UV-C range between 100 and 280nm, in which at least two wavelengths occur, one of which is at >200nm in the longer wavelength range of <200nm and the other in the shorter wavelength range of <200nm. Preferred as UV light source is therefore a corresponding light source which produces a first radiation maximum of longer wavelength in the wavelength range >200 nm and a second radiation of shorter wavelength in the wavelength range <200 nm maximum value. Of course, instead of UV light sources with two or more wavelength ranges, conventional UV light sources with only one wavelength maximum, for example 254 nm, can be used.

Finally, another aspect of the invention relates to a control device by means of which a fan, a UV light source and a pump for supplying a humidification device with mineralized water are actuated. In this case, the corresponding control circuit for the marine climate air-conditioning device according to the invention has in particular a switch-on delay unit which first switches on the UV light source and the pump and after a predetermined delay time, for example after 5 min Just turn on the fan. This ensures that, before the room air is exchanged by switching on the fan, a corresponding marine climate first develops inside the marine climate air-conditioning unit and eventually kills any microorganisms that may be present.

Furthermore, it has been found that an air duct can be advantageously provided between the fan and the salt bath unit, which air duct guides the air sucked in by the fan into the salt bath unit. This avoids turbulence on the one hand, which leads to a considerable noise reduction, and on the other hand improves the passage of the air flow through the salt bath unit. It is also advantageous if the air channel is only subjected to the air flow to a part of the salt bath unit, while other regions of the salt bath unit are shielded on the fan side outside and/or inside the air channel by bulkheads or partitions. Although the covered area is still flooded or penetrated by water in the vertical direction, it only contributes to the atomization to a limited extent, since the covered area is not or only slightly penetrated by air. Water consumption can be limited in this way. Here too, the bulkhead can be arranged in an adjustable manner, so that the atomization quantity can be easily adapted to the user's requirements or the size of the space.

detailed description

FIG. 1 shows schematically the mode of operation of a marine climate air-conditioning device 1 according to the invention in a schematic sketch. The marine climate-conditioning device 1 comprises a housing 2 , the lower region 2 ′ of which is designed in the form of a tank and serves as a container for sea-salt-containing water 3 . The housing 2 has an air inlet 4 , upstream of which a filter 4 ′ for suspended solids, fine particles, pollen, etc., can additionally be arranged. Furthermore, the housing 2 has an air outlet 5 . Arranged in the housing 2 is a fan 6 which sucks in room air through the air inlet 4 and generates an approximately straight air flow 6 ′ through the marine climate-conditioning device 1 towards the air outlet 5 .

Arranged downstream of the fan 6 in the direction of flow is a salt bath unit 7 through which the air flow 6 ′ flows in the horizontal direction in the direction of the air outlet 5 . The salt bath unit is vertically flowed through by brine, which wets the minute branches and structures of the salt bath unit 7 and flows along them. For this purpose, a pump 8 is provided, which in this embodiment is designed as a submersible pump, which conveys brine from the trough-shaped lower housing 2 ′ via a line 9 to a distribution channel 10 arranged above the salt bath unit 7 . Of course, instead of a submersible pump, a suction pump can also be used, which can be arranged in the upper region of the air conditioner.

Distribution channels 10 extending perpendicularly to the plane of the drawing distribute the brine delivered by the pump 8 evenly over the width of the salt bath unit and introduce the brine into the salt bath unit from above. Due to the finely branched flow guide structure of the salt bath unit, which is wetted with brine and overflows, the salt bath unit outputs moisture and salt minerals to the air stream 6'. After flowing through the salt bath unit 7 , the brine drips back into the lower housing 2 ′ serving as a water tank when it is not output to the air flow 6 ′.

A simulated climate chamber 11 is connected to the salt bath unit 7 in the flow direction, which passes laterally through the housing wall of the housing 2 and downwards through the housing bottom or the level 3 of the liquid level 3 in the lower housing 2'. The water surface is bounded upwards by the cover 14 and in the direction of the air inlet 4 by the surface 7 ′ of the salt bath unit 7 facing the simulated climate chamber 11 .

The main elements of the simulated climate chamber 11 are UV lamps 12 which are arranged in the upper region of the simulated climate chamber 11 . The UV lamp 12 illuminates on the one hand the air volume of the air flow 6 ′ through the simulated climate chamber 11 , on the other hand the surface 7 ′ of the salt bath unit 7 facing the simulated climate chamber 11 and finally also the surface located in the lower housing 2 ′ The water surface of the salt water 3. Various physico-chemical processes and reactions, which will be explained further below, take place here. Furthermore, an ionization device 13 is arranged inside the climate chamber 11 , which acts on the air flow 6 ′ flowing through the climate chamber 11 and generates a negative charge of atoms and molecular groups.

The UV lamp 12 produces short-wave UV light in the UV-C range between 280 and 100 nm. The radiation spectrum produced by the UV lamp 12 has a first radiation maximum at a longer wavelength of about 254 nm, and a second radiation maximum at a shorter wavelength of 185 nm. According to the insight of the invention, such a radiation spectrum with at least two wavelengths in the range >200 nm and <200 nm is ideally suited for inducing and supporting the desired chemical reactions. While the light fractions of longer wavelengths primarily lead to the bactericidal effect known per se through their microbiological efficacy, the light fractions of shorter wavelengths contribute to the chemical reaction, especially in the presence of ozone (O ₃ ), according to the present invention. Get involved.

It is pointed out here, however, that the invention is by no means restricted to the use of UV lamps with two or more wavelengths. Instead, conventional UV lamps with only one wavelength or only one wavelength range, for example 254 nm or 185 nm, can also be used within the scope of the invention.

In the exemplary embodiment, the salt bath unit 7 is formed by a salt bath mesh made of porous filter foam having a pore size of approximately 20 ppi. The filter foam is made of open-cell flexible polyurethane foam with a plastic content of only 3% by volume. Such filter foams are available, for example, under the trademark Panapor PPI 20S and have high UV- and saline stability. Due to the large pore size and its open-cell structure, the filter foam acts non-absorbent and has no capillary properties. In contrast, filter foam is only permeable to water and air with low flow resistance and provides an ideal structure for salt bath units. Of course, the invention is not limited to the use of this particular filter foam, but many other types of entanglements, fabric or braid arrangements, branched or unbranched, may be used in salt bath units.

In order to understand the process simulated by the present invention, Figure 2 shows in a schematic diagram the factors involved in the formation of the ocean climate. This is on the one hand the mineral-rich sea water 20 with its large number of different salts and other minerals, on the other hand the influence of solar radiation 21 , especially the UV-C fraction contained in it, and finally the coastal The ocean waves 22, in addition to spraying water, also cause negative ionization due to triboelectricity. It is the combination of these three factors in a common "activation space" that results in the ocean climate that the present invention attempts to simulate. The simulated climate chamber 11 simulates this activated space.

According to the principle of the marine climate air-conditioning device 1 shown in FIG. 1 , the energy-rich UV-C radiation of the UV lamp 12 has reached the liquid film on the surface 7 ′ of the salt bath mesh 7 and causes water- and the decomposition of salt particles, water and salt particles are thus transformed into highly soluble fractions that are more easily exported into air currents, like rocks that are continuously washed by waves in the edge regions of the ocean - or as in the case of the beach shore.

At the same time, energy-rich UV-C radiation acts on the moisture-laden and mineralized air flow 6' inside the simulated climate chamber 11, the central region 11' of which serves as an "activation region". The UV radiation acts on the combined structure of the water, its dissolved minerals and the air molecules of the humidified air flow and triggers various reactions there. Here too, activated molecules and chemical groups are formed, in particular in the form of singlet oxygen, which is positively excited and then "discharges" again in the water vapor and outputs the absorbed energy into the water molecules.

The ionization device 13 generates an electric arc by means of a high-voltage plasma discharge, for example 10 kV, which leads to the formation of different chemical groups and ionized molecular or atomic groups in the air stream. Atoms or molecules with at least one unpaired electron are referred to here as chemical groups, most of which are especially reactive.

In summary, the following temporary and permanent groups of atoms or molecules are produced in the activation space: H ² O, H+, O=, H, OH, O ² , O ³ , H ² O ² , O ² H, Cl ² , ClO, ^Cl2O , and various decomposed mineral fractions, which correspond to those in the surf zone and contribute to the well-known health-promoting and healing marine climate.

On the other hand, measurements in indoor air outside marine climate air-conditioning units show little increase in ozone concentration. This is the case primarily due to the influence of the ionization device 13, which immediately reduces the ozone formed under the action of the short-wave UV-C fraction, but here results in a depletion of the water molecules and mineral fractions contained in the air flow. Positively motivate or activate.

FIGS. 3 to 8 show exemplary embodiments of a marine climate conditioning device according to the invention, which works according to the principle explained in FIG. 1 .

FIG. 3 shows the marine climate air-conditioning device 1 in an isometric exterior view. It has a two-part housing 2 with a lower housing 2' and an upper housing 2". An air inlet 4 with a ventilation grill is located in the upper housing 2". The air outlet is arranged hidden from the air inlet 4 and thus in FIG. 3 . On the front side of the air conditioner 1 there is also an operating area 15 via which the air conditioner can be put into operation and can be adjusted in various ways. For example, timer functions or different ventilation phases can be adjusted.

The opened air conditioner is shown in side view in FIG. 4 . Here, the upper housing 2" is removed from the lower housing 2' together with the contents of the air conditioner 1 connected thereto. This facilitates the cleaning of the lower housing 2', which at the same time serves as Collection tanks and containers for water used to humidify the air and mineralized with sea minerals.

The “content” of the marine climate-conditioning device 1 is to be understood as the base plate 16 , which is connected to the upper housing 2 ′ by means of three tubular struts 18 . A pump 8 configured as a submersible pump is fastened to the bottom plate 16 , which pumps water via a line 9 from the container to the upper region of the salt bath network 7 located behind the pump. The salt bath net 7 is made of the aforementioned filter foam and is held in a frame 17, which is detachably connected to the upper housing 2″, so that the salt bath net 7 can be removed for cleaning when required and can also be removed when required. Can be replaced.

The base plate 16 here primarily serves as a carrier for the pump 8 . Alternatively, however, the pump 8 can also be fastened directly to the frame 17 of the salt bath grid 7 if the frame is designed to be stable accordingly, so that the base plate 16 and the associated support 18 can be omitted.

FIG. 5 shows a view of the marine climate air-conditioning device 1 from above, the dotted lines showing the hidden contours of the air-conditioning interior. On the right side in the housing 2 there is an air inlet which is provided with a corresponding microporous filter. On the left side there is an air outlet 5 . A fan 6 is arranged behind the air inlet 4 . On the bottom of the air conditioner there is a pump 8 which delivers the sea water through a line 9 to a distribution channel 10 which is located above the salt bath network 7 . The salt bath net 7 arranged approximately in the middle of the housing 2 divides the interior space of the air conditioner and thus forms, on its side facing away from the fan 6, a simulated climate chamber 11 above which there are UV lamps 12 .

Further to the left of the UV lamp 12 there is an ionization device 13 , shown in dotted lines, which ignites an electric arc by means of a high-voltage discharge, which leads to ionization of the molecules and aerosols located in the simulated climate chamber. Also in the upper region of the air conditioner, below the operating area 15 there is a control device 19 , shown here only schematically, which actuates the fan 6 , the pump 8 , the UV lamp 12 and the ionization device 13 .

FIG. 6 shows a section along the section line A-A in FIG. 5 . It can be clearly seen here that the salt bath net 7 and its frame 17 arranged vertically in the air conditioner in the middle and the distribution channel 10 extending approximately horizontally above the salt bath net pass into the distribution channel from the pump. Line 9 of 8. A fan 6 is arranged on the right side of the salt bath net 7 , and the fan sucks external air through the air inlet 4 and generates an air flow, which flows through the salt bath net 7 .

To the left of the salt bath grid 7 and adjacent to it there is a simulated climate chamber 11 . The simulated climate chamber 11 is delimited on three sides by the housing 2 , on the right side towards the fan 6 by the salt bath mesh 7 and upwards by the cover 14 above which there are the electronic components in the control device 19 and the UV lamp 12 . This UV lamp illuminates the simulated climate chamber 11 and both the humidified air volume flowing through the simulated climate chamber 11 and the surface of the salt bath net 7 facing the simulated climate chamber 11 as well as the surface in the lower housing 2'. liquid volume. The cover 14 is part of the inner casing 2a located inside the upper casing 2", so that the upper casing 2" can be removed separately without the contents of the air conditioner, for example to replace UV lamps or Maintenance controls 19 . A UV transparent window can optionally be provided before the UV lamp 12 .

In FIG. 7, the upper housing 2″ is removed separately, so that the UV lamp 12 and the control module 19 can be accessed. Furthermore, it is also possible in this state to replace the microporous filter ( not shown).

The control module 19 here includes in particular the aforementioned control circuit, which has a switch-on delay unit, which first switches on the UV light source and the pump, and only switches on the fan after a predetermined delay time, for example 5 min. In addition, however, the control module 19 also controls various other operating parameters, such as timer functions or different ventilation phases, in accordance with the user input via the control panel 15 .

Finally, FIG. 8 shows an isometric view of the marine climate air-conditioning unit with the lower housing 2' removed, enabling access to a simulated climate chamber 11 divided by a salt bath net 7 and irradiated by UV light with the aid of UV light. observation. The underside of the pump 8 is visible through the suction opening in the base plate 16 . A part of the fan 6 can also be seen on the right rear side of the salt bath net 7 and its holding frame 17 . Above the salt bath grid 7 there are distribution channels 10 , from which the mineralized water is discharged into the salt bath grid in such a manner that it is evenly distributed over the width of the salt bath grid.

Measurements are shown in FIG. 9 showing the output of salt into the air stream by a salt bath unit according to the invention compared to pure evaporation. The numerical value indicates the salt concentration in grams/liter. The first column relates to an initial value of 33.7 g/l, as occurs in normal sea water. The second column 32 indicates the salt concentration in the residual water remaining in the marine climate conditioning unit after 24 hours of operation. This has risen slightly to 43.7g/l. The third column shows comparative values where the same amount of liquid was drawn from the brine by pure evaporation. Here, the salt concentration rose to 59.25 g/l. The fourth column 34 shows the salt output to room air under pure evaporation, which is measured. With pure evaporation, only 5.75 g/l of salt is exported to the room air. In contrast to this, the last bar 35 shows the output of salt to the room air by the salt bath unit according to the invention. This salt output is 15.55 g/l in total over a 24-hour measuring period and is thus three times greater than, for example, when humidifying the air by evaporation of sea water. The measurements thus impressively demonstrate the advantageous effect of the salt bath unit according to the invention through which brine flows in the vertical direction or of the salt bath nets used therefor.

The above exemplary determination of the delivery power of the circulation pump and the dimensioning of the air flow circulated by the fan relates to typical air conditioners for operation and to the air conditioning of rooms of the order of magnitude between 20 and 100 qm, as for example in typical as it would occur in the habitation situation that arises locally. However, it should be pointed out at this point that the invention is by no means restricted to air conditioners designed in this way. Instead, larger or smaller air conditioners can be realized according to the principle of the invention, wherein the dimensioning can be adapted to the respective application. For example, a correspondingly designed marine climate air conditioner can be integrated into the ventilation system of larger living or office complexes in order to centrally supply several rooms with marine climate or correspondingly humidified, mineralized and activated air. It is likewise possible to design a scaled-down version of the air conditioner for supplying only smaller rooms, for example in hotels.

FIG. 10 shows a refinement of the marine climate conditioning system shown in FIGS. 3 to 8 . Here, the upper part 2 ″ is removed, so that the salt bath mesh 7 with the distribution channels 10 held in the frame 17 can be seen therein. An air channel 40 is arranged in front of the salt bath mesh 7 , in the assembled state The same fan removed here is positioned on the front opening of the air channel. Therefore, the air channel 40 is positioned between the fan and the salt bath net 7, and guides the air sucked by the fan to the salt bath net 7. Thus avoiding Eddy current and turbulent flow are eliminated, and eddy current and turbulent flow can easily form disturbing noise or shield the fan noise. Thus the air conditioner has significantly less noise in operation. In addition, the air flow through the salt bath net 7 has been improved.

Furthermore, the edge region of the salt bath screen 7 is shielded on the side of the fan by a bulkhead 41 surrounding the air channel 40 . Part of the salt bath net 7 within the cross section of the air channel 40 is shielded by the bulkhead 42 . Thus, only a part of the salt bath mesh 7 is loaded by the air flow, while other parts of the salt bath mesh 7 are shielded. Although the shaded area is already flooded or penetrated by water in the vertical direction, it only contributes to evaporation to a limited extent because it is not or only slightly penetrated by air. In this way water consumption can be limited. In particular, the bulkhead 42 can be adjusted so that the evaporation rate can be adapted to the needs of the user or to the size of the space by enlarging or reducing the area through which the air flows.

It can also be seen in FIG. 10 that the bulkhead 41 is part of a plug-in frame 17 or drawer into which the salt bath net 7 is inserted from above together with an internal holding frame (not shown). Therefore, the salt bath mesh can be simply replaced when it becomes dirty or encrusted. Thus, the salt bath screen itself, which can be produced extremely cheaply using a corresponding filter foam screen, can be designed as a replaceable or consumable part and be provided as a spare.
