Description

The present invention relates to a marine air conditioner with 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.

A generic marine air conditioner is for example from the DE 3518456 A1 known. The local, designated as a healthy air conditioner device has a humidifier as a spraying device for generating a mist of seawater, and a fan for generating a traversing the spray and entrained in the outer air flow. In addition, a UV light source is provided, which is arranged in the region of an air inlet opening and irradiates both the intake of the fan room air and the seawater located in a tub for fogging with UV light. In this way, a room climate is to be generated, which corresponds to the conditions in the region of the sea surf, in particular, the full influence of the solar spectrum in the entire UV range should be modeled.

The device shown has on the one hand various technical defects. Thus, among other things, the spraying of saline water through the sprayer leads to salt encrustation within the device, in particular to the spray nozzles themselves, which can affect the functionality of the device within a short time. In addition, by the salty spray metallic and in particular electrical components of the device, such as the fan and the UV light source can be attacked by corrosion and damaged. In addition to these technical deficiencies, however, the device also shows only a limited effectiveness in terms of health-promoting influence and increase the well-being of the room climate generated by the device.

In addition, various other healing air conditioners and humidifiers are known. In the DE 100 54 562 A1 For example, a remedial air conditioner is described in which a generated by a blower air flow is passed through a curtain of water droplets and so moistened. In addition, a UV light source is provided for irradiating the water present in a water reservoir in order to kill any microorganisms present in the water.

From the DE 102 53 842 A1 is a healing air conditioner known in which a humidification of an air flow, for example by means of a water-soaked fleece, which is flowed through by the air flow. Again, a UV light source is provided, which is located above the water reservoir and irradiates the water surface to kill any bacteria or bacteria contained in the water. In addition, an ionization device is described, which should be arranged so that the ions emitted by it are fed to the air flow.

In the DE 440497 describes a healthy air conditioner, in which sucked outside air is passed through a droplet curtain formed from liquid. In turn, UV radiation from a UV light source acts on the liquid in a reservoir. In addition, a restructuring of the liquid or liquid droplets is to be achieved by low-frequency electromagnetic signals, which should have a favorable effect on the healing climate air.

Finally, from the Scriptures US 4,686,069 a humidifier is known in which a stream of air is humidified by means of an air-permeable medium such as a porous sponge, which is located between two high-voltage charged electrodes. The porous sponge dips with its lower end in a water-filled tub and so sucks by capillary forces with water, which is discharged to the air flow. Such a construction is unsuitable for operation with saline water, since the evaporation on the surface of the sponge would rapidly lead to salinisation of the sponge.

The present invention has therefore set itself the task of creating a marine air conditioner, which is improved in terms of the effectiveness of the indoor climate generated by it and in particular the actual marine climate creates much closer conditions. In addition, the present invention provides various technical improvements that significantly differentiate the marine air conditioner in terms of reliability, ease of maintenance, durability, operating noise, but also manufacturing costs compared to conventional devices.

The present invention is based, above all, on a deeper understanding of the factors which influence the marine climate and of the physical-chemical processes taking place in the process.

The object is solved by the features of claim 1. Advantageous embodiments are given in the dependent claims.

In a generic marine air conditioner, the object is achieved in that the humidifying device can be flowed through by the air flow and arranged in the flow direction, that one to the humidifying adjacent and arranged in the flow direction behind the humidifier climate chamber is provided and that the UV light source is arranged such that it irradiates the climate chamber flowing through the humidified air flow and pointing to the climatic chamber, air-flow surface of the humidifier with UV light.

The teaching according to the invention is based, in particular, on the knowledge that the action of UV radiation on the humidified and mineralized air stream brings about a particular physico-chemical activation of the molecules and molecular groups contained therein. At the same time, the high-energy UV radiation already on the surface of the moistening device causes a dissociation of the water and salt particles and converts them into highly soluble fractions, which can be released more easily to the air stream. Various physical-chemical processes triggered thereby lead to an activation simulated by the sea surf, which can be detected in the room air after a short time during the operation of the device both in terms of smell and taste.

Thus, according to the inventor's knowledge, it is not the effect and the microbiological effectiveness of the UV radiation on the liquid or standing water volume which is important, but also the effect on the humidified and mineralized air stream but also the salt surface wetted with salt water, on the water molecules and minerals the air flow are discharged.

The efficiency of the marine air conditioner can be further increased if, in addition, an ionization device is provided for the ionization of molecules contained in the air flow. It is essential here that the ionization device also acts within the climatic chamber on the humidified air flow flowing through it. Such an ionization device, which can be realized, for example, by the arc discharge of a high-voltage discharge unit biased at approximately 10 kV, simulates a state which occurs due to static electricity in surf and spray, and which leads to a charge transfer and ionization at chemical radicals and molecular charges. or atomic groups in the air stream leads.

According to a further, particularly advantageous aspect of the present invention, the moistening device comprises a grading unit, which vertically flows through or flows through the mineralized water and is flowed through horizontally by the air flow. Such a grading unit consists of a multiplicity of fine structures, which form as it were a flow-guiding framework, which is coated with a fine liquid film by the salt water flowing through the grading unit and thus, on the one hand, a large surface area for the delivery of minerals and water molecules to the air flow, but on the other hand its open porosity forms only a small flow resistance for the air flow. Such a grading unit thus represents a replica and miniaturization of the graduation works, which are still to be found today in various health resorts, in which brine is passed through Reißig, which is stacked in the form of large bundles in a wooden frame.

In addition to a large surface area, such a grading unit also ensures that salt deposits and incrustations can not form due to the liquid flow continuously flowing through the grading unit in the vertical direction, which would disturb the air passage and prevent a moisture transfer to the air flow. In addition, it is avoided in comparison to spray nebulizers that salt water and salt deposits can get to metallic or electrical components, seals or the like, where they can lead to corrosion and material damage.

Preferably, the grading unit is made of a UV and salt water resistant material. In the context of the present invention, polyester is preferred as the material for the grading unit of which it at least partially consists.

An embodiment that is particularly easy to implement results when a grading mat, which consists of a non-absorbent material, is used as the grading unit. In particular, such a grading mat should therefore not be capillary and thus not water-storing, since this would lower the air permeability on the one hand and cause salinisation of the grading mat on the other hand due to the stored water volume.

In the context of the present invention, in particular an open-pored filter foam, for example based on polyester or polyurethane, is preferred as the material for the grading mat. In order to achieve good air permeability, the filter foam should have a pore width of at least 0.5 to 2.5 mm. The proportion of plastic in the filter foam should be less than 8% by volume, preferably 2-4% by volume, most preferably about 3% by volume. The pore width in such a filter foam is often determined in units of pores per inch (ppi). The preferred pore size in the context of the present invention is 10 to 30 ppi, preferably about 20 ppi on average.

Alternatively, the grading unit can also consist of a tangle, fabric or mesh of fine structures, such as polyester threads, wherein the previously said in terms of volume fraction also applies here.

In the inventive operation of the Gradiereinheit sets in the climatic chamber in contrast to nebulizers, a relative humidity of <100%, preferably <80%, so that it does not come to liquid precipitation in the housing and especially not outside the device in front of the air outlet opening ,

In a preferred embodiment of the marine air conditioner according to the present invention, a lower portion of the apparatus is formed as a trough, which serves as a reservoir for mineralized water and is also irradiated by the UV radiation source with UV light. On the one hand, in this way the microbiological effectiveness of the UV light is exploited in order to keep the salt water in the water reservoir sterile, on the other hand the water flowing through the grading unit can then drip back into the trough formed as a reservoir, so that a continuous circulation of the water Water volume is guaranteed.

Preferably, the marine air conditioner includes a pump that conveys the mineralized water from a reservoir to an upper portion of the grading unit, from where it flows over and / or through the grading unit. In this case, a distribution channel arranged above the grading unit can preferably be provided, through which the water is distributed substantially uniformly over the width of the grading unit and delivered to it. The pump has to promote in this case, only mineralized water from the reservoir into the distribution channel, so that only low technical requirements for pump power and flow rate must be made, so the pump can be built according to simple and inexpensive.

The pump can in this case be arranged both in the form of a submersible pump within the water reservoir or in the form of a suction pump above the water reservoir and preferably above the grading unit. The delivery rate of the pump is preferably in the range between 50 and 300 l / h.

According to the recognition of the present invention, the UV light source is preferably arranged in or above the climatic chamber, so that the UV radiation emitted by the UV radiation source becomes effective, above all, in the climatic chamber and on the surface of the moistening device facing the climate chamber. The radiation power of the UV light source or the light intensity irradiated by the UV light source in an activation area of the climate chamber is preferably in the range between 10 and 20 mW / cm ² , most preferably at about 15 mW / cm ² .

In departure from most known devices in which an attempt was made to produce a stak air flow as possible in order to circulate as much room air, the invention recognizes that even a very light draft through the device is sufficient to achieve the effect of the invention. The gas exchange within the living space to be conditioned does not take place here by convection, ie by large-volume air flows, but rather by diffusion processes for concentration equalization according to Gay-Lussac's law or Fick's laws of diffusion.

In order to allow these diffusion processes to proceed as unhindered as possible, in the marine air-conditioning appliance according to the invention fans, humidifying device and climatic chamber are arranged such that the airflow flows through the marine air-conditioning device from an air inlet to an air outlet essentially in a straight line. In particular, care is taken in the device according to the invention that the air flow is not fluidly directed by means of ventilation ducts, guide and deflection surfaces.

Since according to knowledge of the present invention already a very weak air flow with low flow velocity and low volume flow is sufficient to achieve the effect according to the invention, the fan can be correspondingly small in size and run slowly running, so that disturbing fan noise can be reduced. In particular, compact and quietly running fans, such as those installed in computer housings, can be used. In order to minimize fan noise, in particular a so-called bionic fan, that is to say a fan with a bionically optimized rotor design, can be used. Preferably, the fan is dimensioned and operated to circulate an air volume in the range of 20 to 80 m ³ / h, more preferably in the range of 30 to 60 m ³ / h and most preferably in the range of 40 to 50 m ³ / h, and moved through the climatic chamber.

According to the invention, it is particularly preferred if an air flow is generated by the fan, which flows through the grading unit substantially laminar. This is achieved by correspondingly low flow velocity and correspondingly high air permeability of the grading unit.

Particularly effective in terms of the physico-chemical processes involved in the production of the marine climate, a UV Radiation in the UV-C range between 100 and 280 nm proven in which at least two wavelengths occur, one of which is in a longer wavelength range> 200 nm, the other in a shorter wavelength range <200 nm. As a UV light source, therefore, a corresponding light source is preferred which generates a first, longer-wave radiation maximum in a wavelength range> 200 nm, and a second, shorter-wavelength radiation maximum in the wavelength range <200 nm. Of course, but instead of a UV light source with two or more wavelength ranges, a conventional UV light source with only one wavelength maximum, for example, 254 nm can be used.

Finally, another aspect of the present invention relates to a controller with which fan, UV light source and a pump for feeding the humidifier with the mineralized water are controlled a corresponding control circuit for a marine air conditioner according to the invention in this case in particular a switch-on delay, which initially the UV Light source and the pump turns on and only after a predetermined delay time, for example after 5 min, hinzuschaltet the fan. This ensures that a corresponding marine climate can first form within the marine air conditioner and any microorganisms present may be killed before an exchange with the room air takes place by switching on the fan.

Further features, advantages and features of the present invention will be explained below with reference to the figures and embodiments. It shows

In 1 is the operation of a marine air conditioner according to the invention 1 shown schematically in a schematic diagram. The marine air conditioner 1 includes a housing 2 whose lower area 2 ' is designed in the form of a tub and as a reservoir for meersalzhaltiges water 3 serves. The housing 2 has an air inlet opening 4 , in front of the additional filter 4 ' may be provided for suspended matter, fines, pollen and the like. In addition, the case has 2 an air outlet 5 , In the case 2 is a fan 6 arranged through the air inlet 4 Room air sucks and a roughly linear air flow 6 ' through the marine air conditioner 1 towards the air outlet opening 5 generated.

Behind the fan 6 is a grading unit in the flow direction 7 arranged, which of the air flow 6 ' in the horizontal direction towards the air outlet 5 is flowed through. In the vertical direction of the graduator of salt water is flowed through, which the fine ramifications and structures of the grading 7 wetted and flows along these. This is a pump 8th provided, which is formed in the embodiment as a submersible pump, which via a pipe 9 Salt water from the tub-shaped housing bottom 2 ' to one above the grading device 7 arranged distribution channel 10 promotes. Of course, instead of a submersible pump and a suction pump can be used, which can be arranged in an upper region of the device.

The vertical to the drawing plane extending distribution channel 10 distribute this from the pump 8th pumped salt water evenly across the width of the grading device and introduces it from above into this. Due to their finely branched flow-conducting structures, which are wetted and overflowed by salt water, the Gradiereinheit adds moisture and salt minerals to the airflow 6 ' from. After flowing through the grading unit 7 the salt water drips, as far as it does not adhere to the air flow 6 ' was discharged, back into the serving as a water reservoir housing lower shell 2 ' ,

To the grading unit 7 closes in the flow direction of a climate chamber 11 to which laterally through the housing walls of the housing 2 , down through the housing bottom or the water surface of the housing lower shell 2 ' located liquid level 3 , upwards through a cover 14 and in the direction of the air inlet opening 4 through the climate chamber 11 facing surface 7 ' the grading unit 7 is limited.

Essential element of the climatic chamber 11 is a UV lamp 12 , which are in the upper part of the climatic chamber 11 is arranged. The UV lamp 12 On the one hand, this irradiates the climate chamber 11 flowing air volume of the air flow 6 ' , on the other hand, the climate chamber 11 facing surface 7 ' the grading unit 7 and finally the water surface of the inside of the housing 2 ' salt water 3 , Here, various physical-chemical processes and reactions take place, which are explained in more detail below. Moreover, inside the climate chamber 11 an ionizer 13 arranged on which the climatic chamber 11 flowing airflow 6 ' acts and generates negatively charged atomic and molecular groupings.

The UV lamp 12 produces a short-wave UV light in the UV-C range between 280 and 100 nm. That of the UV lamp 12 generated radiation spectrum has a first longer-wave maximum radiation at about 254 nm and a second, shorter-wavelength maximum at 185 nm. According to the present invention, such a radiation spectrum with at least two wavelengths in the range> 200 nm and <200 nm ideal for bringing about and supporting the desired suitable for chemical reactions. While the longer-wave light component by its microbiological effectiveness mainly causes the known disinfecting effect, according to the invention, the shorter-wave light component supports the mentioned chemical reactions, above all with the participation of ozone (O ₃ ).

It should be noted, however, that the invention is by no means limited to the use of a UV lamp having two or more wavelengths. Rather, in the context of the present invention, it is also possible to use conventional UV lamps having only one wavelength or only one wavelength range, for example either at 254 nm or at 185 nm.

The grading unit 7 is formed in the embodiment by a Gradiermatte made of open-pored filter foam, which has a pore size of about 20 ppi. The filter foam consists of an open-cell flexible polyurethane foam with a plastic content of only 3 vol.%. Such a filter foam is available, for example, under the trade name Panapor PPI 20 S and has a high UV and salt water stability. Due to the large pore size and its open-cell structure, the filter foam is non-absorbent and exhibits no capillary properties. Rather, the filter foam with only low flow resistance of water and air can flow through and provides an ideal structure for the Gradiereinheit. Of course, the present invention is not limited to the use of this particular filter foam, but may be used in the Gradiereinheit a variety of other arranged in the manner of a tangle, fabric or braid, ramified or undamaged structures.

To understand the processes simulated by the invention shows 2 the factors involved in the formation of a marine climate in a schematic representation. On the one hand, this is the mineral-rich seawater 20 with its variety of different salts and other minerals, on the other hand, the influence of solar radiation 21 and here in particular the UV-C content contained in the solar radiation and finally the surf 22 on the coast, which leads to a negative ionization due to static electricity in addition to an atomization of the water. Only the interaction of these three factors in a common "activation space" leads to the formation of a marine climate, which seeks to mimic the present invention. This activation space is the climatic chamber 11 to.

According to the principle of in 1 shown marine air conditioner 1 reaches the high-energy UV-C radiation of the UV lamp 12 already the liquid film on the surface 7 ' the graduation mat 7 and results in dissociation of the water and salt particles at this interface, which are thereby converted into a highly soluble fraction allowing for easier delivery to the airflow, similar to a rock or beach coast continuously overflowed by the surf in the hem area of the sea the case is.

At the same time, the high-energy UV-C radiation acts on the moisture-laden and mineralized air flow 6 ' inside the climatic chamber 11 whose central area 11 ' serves as an "activation area". The UV radiation intervenes in the bonding structures of the water, its dissolved minerals and the air molecules of the humidified air flow and triggers a variety of reactions there. Among other things, activated molecules and chemical radicals are formed, in particular in the form of singlet oxygen, which energetically excites then "discharges" again in the water vapor and releases the absorbed energy to the water molecules.

The ionization device 13 generated by means of plasma discharge of a high voltage of, for example, 10 kV an arc, the formation different chemical radicals and ionized molecule or atomic groups in the air flow leads. Chemical radicals are atoms or molecules with at least one unpaired electron, most of which are particularly reactive.

Overall, the following temporary as well as permanent atomic or molecular groupings arise 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, Cl ² O-
as well as a variety of dissociated mineral fractions, which correspond to those in the marine surf area and contribute to the well-known health-promoting and healthy oceanic climate.

On the other hand, measurements in the room air outside the marine air conditioner show hardly any increase in the ozone concentration. This circumstance becomes especially the influence of the ionizing device 13 attributed, which immediately degrades the ozone formed under the action of short-wave UV-C shares again, but this causes an energetic excitation or activation of the water molecules contained in the air flow and mineral fractions.

In the 3 to 8th an embodiment of a marine air conditioner according to the invention is shown, which after the in 1 explained principle works.

In 3 is the marine air conditioner 1 shown in an isometric view. It has a two-part housing 2 with a housing lower shell 2 ' and a housing upper shell 2 '' on. In the housing upper shell 2 '' There is an air inlet opening provided with a ventilation grille 4 , Opposite the air inlet opening 4 and therefore in 3 concealed an air outlet opening is arranged. At the top of the device 1 there is also a control panel 15 , via which the device can be put into operation and various settings can be made. For example, a timer function or different fan levels can be set.

In 4 the opened device is shown in a side view. Here is the upper housing shell 2 '' along with the associated interior of the air conditioning unit 1 from the lower shell 2 ' decreased. This can be helpful to the lower shell 2 ' which at the same time serves as a sump and reservoir for the air humidification serving mineral water mineralized with sea minerals.

From the "inner life" of the marine air conditioner 1 is a floor plate 16 to see, by means of three tubular struts 18 with the housing upper shell 2 ' connected is. On the bottom plate 16 is a pump designed as a submersible pump 8th fastened over a pipeline 9 Water from the reservoir to an upper area of the Gradiermatte located behind the pump 7 promotes. The gradation mat 7 consists of the above-explained filter foam and is in a frame 17 held, the detachable with the housing upper shell 2 '' connected, leaving the gradation mat 7 if necessary, it can be removed for cleaning and replaced if necessary.

The bottom plate 16 serves primarily as a carrier for the pump 8th , Alternatively, the pump 8th but also directly to the frame 17 the graduation matte 7 be fastened, if this is designed accordingly stable, so that on the bottom plate 16 and related struts 18 can be waived.

5 shows a view of the marine air conditioner 1 from above, where hidden contours are shown in dashed lines inside the device. In the case 2 is located on the right side of the air inlet opening, which is provided with a corresponding microfilter. On the left side is the air outlet 5 , Behind the air inlet opening 4 is the fan 6 arranged. At the bottom of the device is the pump 8th passing through the pipeline 9 Seawater to the distribution channel 10 promotes that are above the gradiermatte 7 located. The gradation mat 7 , which is roughly in the center of the case 2 is arranged, divides the interior of the device, thus forming on its the fan 6 opposite side the climatic chamber 11 above which is the UV lamp 12 located.

Further to the left of the UV lamp 12 is indicated by dashed lines the ionizer 13 , which ignites by means of high-voltage discharge an arc, which leads to the ionization of located in the climatic chamber molecules and suspended particles. Also located at the top of the unit is below the control panel 15 the only schematically indicated control 19 which fans 6 , Pump 8th , UV lamp 12 and ionizing device 13 controls.

A section along the section line AA in 5 is in 6 shown. Clearly visible here is the center of the device vertically arranged Gradiermatte 7 with her frame 17 and the above the Gradiermatte approximately horizontally extending distribution channel 10 in which of the pump 8th upcoming pipeline 9 empties. To the right of the graduation mat 7 is the fan 6 arranged, the outside air through the air inlet opening 4 sucks and creates a flow of air, which is the graduation mat 7 flows through.

Left of the graduation mat 7 and adjacent to this is the climatic chamber 11 , The climate chamber 11 will be on three sides of the case 2 limited, right to the fan 6 through the graduation mat 7 and up through a cover 14 , above which are the electronic components in the controller 19 as well as the UV lamp 12 are located. This radiates into the climate chamber 11 into and irradiates both the climate chamber 11 flowing, humidified air volume, as well as the climate chamber 11 pointing surface of gradation mat 7 and in the housing lower shell 2 ' standing liquid volume. The cover 14 is part of one inside the housing upper shell 2 '' located inner shell 2a so that the housing top shell 2 '' can be removed separately without the interior of the unit, for example, to replace the UV lamp when needed or the controller 19 waiting. In front of the UV lamp 12 Optionally, a UV-permeable window can be provided.

In 7 is the housing upper shell 2 '' removed alone, leaving the UV lamp 12 and the control module 19 become accessible. In addition, in this state, a behind the ventilation grille of the air inlet opening 4 be replaced microfilter (not shown).

The control module 19 In this case, in particular, the control circuit described above with turn-on delay, which first turns on the UV light source and the pump and hinzuschaltet only after a predetermined delay time of, for example, 5 minutes the fan. In addition, the control module controls 19 but also various other operating parameters, such as a timer function or different fan levels, according to the via the control panel 15 Entries made by a user.

8th Finally, shows an isometric view of the marine air conditioner with removed housing lower shell 2 ' , the glimpse of the graduation mat 7 divided and irradiated by the UV lamp with UV light climate chamber 11 allows. Through a suction opening in the bottom plate 16 is the bottom of the pump 8th recognizable. Right behind the graduation mat 7 with her support frame 17 is still part of the fan 6 to see. Above the gradier mat 7 is the distribution channel 10 from which mineralized water is distributed evenly across the width of the graduation mat into it.

In 9 are measured results showing the salt delivery to the air flow through the Gradiereinheit invention compared to a pure evaporation. The numerical values indicate salt concentrations in grams per liter. The first column refers to a baseline of 33.7 grams per liter, as found in normal seawater. The second pillar 32 represents the salt concentration of residual water remaining in the marine air conditioner after 24 hours of operation. This has increased slightly to 43.7 grams per liter. The third column shows a comparison value in which the same amount of liquid was removed from the brine by pure evaporation. The salt concentration increases to 59.25 grams per liter. The fourth bar 34 represents the salt output to the room air with pure evaporation, which results from the measurement. With pure evaporation, only 5.75 grams per liter of salt were released into the room air. The last pillar 35 shows in comparison to the salt delivery to the room air through the Gradiereinheit invention. This was a total of 15.55 grams per liter over the 24-hour measurement period, which is about three times higher than humidification due to the evaporation of seawater. The measurement thus impressively demonstrates the advantageous effect of the graduation unit flowed through by salt water in the vertical direction according to the invention or of the graduation mat used for this purpose.

The above-exemplified dimensioning with respect to the capacity of the circulating pump and the air flow circulated by the fan refers to a typical device for the operation in and the air conditioning of living space of an order of 20 to 100 square meters, as found in typically occurring housing situations , It should be noted, however, that the invention is by no means limited to a device designed in this way. Rather, larger or smaller devices can be realized according to the principle of the invention, wherein the dimensioning can be adapted to the particular application. For example, a suitably designed marine air conditioning unit can also be integrated into the ventilation system of a larger residential or office complex in order to supply a large number of rooms centrally with maritime climate or correspondingly humidified, mineralized and activated air. It would also be possible to design a miniaturized version of the described device for supplying only a smaller room, for example in a hotel.
