Description

The present invention relates to a device for obtaining drinking water by condensing moisture contained in the ambient air, all the necessary components of the device being arranged in or on a single housing.

A problem in many areas of the world is that access to clean water is not always guaranteed. This can be caused by a general lack of infrastructure in these areas or by catastrophes that (temporarily) (destroy) the infrastructure. In order to give people access to clean water in these areas as well, processes and devices are needed that can provide clean water quickly and reliably. It is known in principle to obtain water by condensing moisture contained in the ambient air on cold surfaces. As an example of this prior art, for example DE 33 13 711 A1 to be named.

Nevertheless, there is still room for improvement, in particular there are hardly any practicable and easily transportable solutions that are particularly suitable for short-term but reliable and self-sufficient use.

The object of the invention was to provide a device which avoids the disadvantages of the prior art and/or improves the prior art. In particular, the device should be able to be used universally and at any location without being dependent on an external power supply. The device should be able to be brought to the destinations worldwide by standardized logistics systems.

Further tasks will become apparent to those skilled in the art upon consideration of the following description and claims.

These and other objects, which will become apparent to a person skilled in the art upon consideration of the present description, are solved by the subject-matter presented in the independent claim.

Particularly advantageous and preferred objects emerge from the dependent claims and the following description.

The present invention is based on the fact that the water absorption capacity of air depends on its temperature; the higher the air temperature, the more water can hold air and vice versa, the lower the air temperature, the less water can hold air. For example, at a temperature of 40°C and a humidity of 90%, each cubic meter of air contains about 0.046 liters of water. Ideally, if this air is cooled by 20°C (i.e. to 20°C), 0.023 liters of water per cubic meter will result from condensation, since air at 20°C absorbs a maximum of 0.023 liters of water per cubic meter.

In the context of the present invention, hot air is sucked or blown into a container and then cooled in a cooling chamber, whereupon the contained humidity (partially) condenses and the condensed water can be collected. This water can be stored and after filtration minerals can be added. The water can then be dispensed (as drinking water).

wherein in the wall of the housing at least one openable and closable opening for

1. A) the intake of ambient air,
2. B) the release of moisture-reduced air to the environment,
3. C) at least one water drainage,
4. D) the inspection of the housing, in particular the machine room,

is provided, or several separate openings are provided for one or more of A) to D), preferably for each of A) to D), at least one separate, individually openable and closable opening is provided,
and wherein the housing of the device according to the invention is a shipping container, particularly preferably a 40-foot container, 20-foot container or 10-foot container, in particular a 40-foot container. The opening for D) is preferably the container door in particular.

In the simplest case, the at least one openable and closable opening is therefore the door of the container and the intake of air, air discharge and water drainage takes place via lines that are arranged inside the container in such a way that they are accessible when the container door is opened.

In other variants of the present invention, openable and closable openings are incorporated into the walls of the container for air intake, air discharge and water drainage, so that the container can be operated with the container door closed. This variant has the advantage that no (or at least fewer) contaminants (e.g. sand) from the environment get into the housing.

In preferred embodiments of the present invention, the ventilation unit blows (or draws in) at least 1000 m ³ per hour of ambient air into the housing, particularly preferably at least 1500 m ³ per hour and in particular at least 1900 m ³ per hour or 2000 m ³ per hour. In variants, a maximum of 4000 m ³ per hour or a maximum of 3000 m ³ per hour are blown in (or sucked in).

In preferred embodiments of the present invention, the cooling element is configured to be tempered to a temperature below the dew point of the ambient air.

The water collection unit is configured to catch and collect the water condensed on the cooling member. In further preferred embodiments of the present invention, the water collection unit is configured to collect the water condensing on the cooling element and direct it to the second filtration unit.

It must be taken into account that it cannot be guaranteed that the condensed water is immediately germ-free, so that further treatment of the condensed water using the second filtration unit and/or the processing unit is necessary in order to obtain drinking water that can be consumed without hesitation.

In the second filtration unit, the condensed water is freed from microorganisms and other impurities. This second filtration unit can be a simple filter. Optionally, the filter can also include antimicrobial substances, for example silver (for example applied to the filter fibers). In further variants of the present invention, this second filtration unit can, alternatively or in addition to microbial substances, also comprise a further water sterilization unit, in particular an ozone generator or a UV irradiation unit.

In further preferred embodiments of the present invention, the further processing units preferably comprise at least one water sterilization unit, in particular an ozone generator or a UV irradiation unit. In this case, the water treatment unit is preferably configured to adjust the water to predefined mineral contents, preferably to drinking water quality. Drinking water quality is understood as described in the German Drinking Water Ordinance (as of October 2022).

It is possible that both the second filtration unit and the further processing unit include water sterilization units, in particular ozone generators or UV irradiation units, just as it is possible that only one of the two includes a water sterilization unit, in particular ozone generator or UV irradiation unit.

In the mineralization unit, the desired minerals are added to the condensed water in the desired quantities. Preferred cations are calcium ions (Ca ²⁺ ), magnesium ions (Mg ²⁺ ) and sodium ions (Na ⁺ ), and preferred anions are carbonate ions (CO ₃ ^2- ), hydrogen carbonate ions (HCO ₃ ^- ), chloride ions (CI ^- ) and sulfate ions ( SO ₄ ^2- ) added. It is possible, for example, to set isotonic concentrations or any other concentrations. Mineralizations that require drinking water quality are preferred.

The mineralization can be done simply by adding mineral tablets to the condensed water.

This can be done either in the mineralization unit, for example by the condensate flowing through the unit and dissolving mineralization tablet(s) in the flow path, or by the unit having a condensate container with a capacity matched to one mineralization tablet; then the mineralization takes place in the tank, which advantageously has at least one stirring element. In this case it makes sense if the supply of condensed water into the unit (and discharge of mineralized water from the unit) takes place in batches.

Or the mineralization takes place in the water reservoir. Accordingly, in some preferred variants of the present invention, the mineralization unit is part of the water reservoir. It is advantageous if the water reservoir comprises at least one stirring element.

Of course, the mineralization does not have to be done with tablets, mineral powder or (concentrated) solutions can also be used.

In further preferred configurations of the present invention, c1) second filtration unit, c2) water treatment unit and c3) water reservoir form a unit or a module, so that the three units can be treated and exchanged as a whole.

In further preferred embodiments of the present invention, the electronics and control of the device includes, for example, elements such as a control cabinet, charging current controller, AC controller, computer system, optional complete AC system, etc.

In principle, the cooling element can be any known from the prior art. It can be selected, for example, according to the place of use or its power requirements or also according to the options for/with connections outside of the device according to the invention. For example, if it could be integrated into an existing coolant line system. Cooling elements that can be used can be based, for example, on Peltier elements or on cooling machines/heating machines based on a thermodynamic cycle process. In the latter case, the cooling element is then in particular the evaporator of a refrigerant circuit or is thermally conductively connected to it.

If the cooling element is based on the evaporation of a coolant, a (preferably) climate-friendly coolant is preferably used as the coolant, in particular R290 (propane). In variants, the device according to the invention is therefore preferably configured to be operated with combustible refrigerants and designed accordingly. If a flammable refrigerant (such as propane) is used, this must be taken into account when designing and designing the device. This means that a system that is designed for non-flammable refrigerants (for example CFCs) cannot easily be used as a device according to the invention for cooling based on R290.

In some preferred embodiments of the present invention, the moisture condenses on metal plates, in particular steel plates, which are arranged vertically or almost vertically (angle to the vertical less than 45°) and then drips down. These metal plates, in particular steel plates, can be thermally conductively connected to, for example, the cool part of a Peltier element or the cool part of a cold/heat pump based on evaporator technology. The metal plates, in particular steel plates, can then also be regarded as cooling elements, since they are then also cooler than the ambient air, optionally with or without the cooling parts to which they are connected, depending on the precise design of the cooling chamber and which parts are arranged inside the cooling chamber .

In other embodiments, it is possible to design the upper inside of the cooling chamber entirely or partially as a cooling element, in which case projections (which can be formed as metal plates, in particular steel plates) can then be designed as a type of drip aid.

Within the scope of the present invention, the metals used for the cooling elements are preferably those metals which are customarily used in the food industry and which are considered harmless in terms of food law. special these are preferably corresponding (high-grade) steels, in particular of the type 1.4301.

In variants of the present invention, the cooling element, in particular the steel, can be coated, with this coating having to be configured in such a way that no harmful substances are released into the condensed water.

Within the scope of the present invention, the cooling elements in the cooling chamber are generally designed with as large an area as possible. In addition, they may have a variety of (smaller) surface features (e.g. ribs or the like) to increase the efficiency of the cooling chamber.

Of course, instead of a Peltier element or a cooling/heating machine, other cooling elements or cooling or cooling machines known in the art can also be used.

In addition, several Peltier elements or several cooling/heating machines or corresponding other elements can be combined with each other, each with corresponding elements of the same type or also elements of different types.

Within the scope of the present invention, the cooling part of the cooling devices (for example from Peltier elements or heat/cold pumps) are thermally insulated from one another by the warmer part. Exactly how this is designed depends on the exact technology used and is sufficiently known to the person skilled in the art; For example, with evaporator technology, the refrigerant can be routed (by pumping) over certain distances, so that the cold and warm parts of the heat/cold pump can be spatially separated from one another in such a way that, for example, the cold part is in the cooling chamber and the remaining part in can be arranged in the machine room.

In embodiments of the present invention, the cooling element is operated and controlled in such a way that icing is avoided. For this purpose the cooling element and/or the cooling chamber can comprise a temperature measuring unit.

In the simplest case, the cooling chamber can be designed as a flow channel/pipeline through which the ambient air drawn in flows along or over the cooling element and the moisture condenses and drips down. In this simplest case, the water collection unit can be a drain in the flow channel/pipeline.

In other preferred embodiments, the chamber is designed as such, for example in the form of a cube, and the water collection unit is designed therein as a kind of trough, bowl or vat in which the condensed water is collected. This tub, bowl or vat can have a drain and/or the collected water can be pumped out of the water collection unit by means of a pump and passed on within the device according to the invention.

In preferred embodiments of the present invention, the device is configured to use the cooled air exiting the cooling chamber for cooling the machine room and/or for discharging into attached or connected rooms (in order to cool them). These rooms can be schools, hospitals, etc., for example, and are connected to the air outlets of the device according to the invention by conventional, preferably standardized, (pipe) lines.

Suitable (pipe) lines for the cooled, moisture-reduced air are laid within the housing of the device according to the invention.

In preferred embodiments, these lines are laid within the device according to the invention in such a way that the cooled, moisture-reduced air can optionally be routed directly to the outside to corresponding pipes and/or can be routed inside the device first partially or completely through the machine room in order to cool it , if necessary or desired.

In further preferred configurations of the present invention, the at least one water reservoir is arranged inside the machine room, it being further preferred if at least two water reservoirs are arranged inside the machine room. In particular, the water reservoirs have a capacity of at least 300 liters each, or of at least 350 liters each, or of at least 400 liters each. Water reservoir can also be referred to as buffer storage. The upper limit of the capacity results only from the space available inside the container, especially inside the engine room.

In further preferred configurations of the present invention, the housing has thermal insulation on the inside and optionally also on the outside and is particularly preferably additionally painted light on the outside, in particular with white paint.

In further preferred configurations of the present invention, a third filtration unit is arranged directly in front of or in the water discharge line, in order to clean the water again immediately before it is discharged.

In preferred configurations of the present invention, the device is configured in such a way that no external power supply is required, but an external power supply is additionally or alternatively possible, preferably through suitable, in particular standardized, adapters, connections if necessary.

• - cooling chamber,
• - water treatment unit, optionally together with the second filtration unit,
• - water reservoir,
• - engine room,
• - photovoltaic elements,

are designed as modules.

In further variants of the present invention, the device comprises a unit for heating the mineralized water, for example a flow heater (which can optionally also be supplied with the device's own photovoltaics). This makes it possible to dispense heated water as well, if desired.

In further variants of the present invention, the device comprises a unit for cooling the water located in the water reservoir if it is to be stored for a longer period of time, for example.

Although the present invention is described in connection with the condensation of water, it is also conceivable to use the devices for the condensation of other substances from ambient gas mixtures. Depending on the liquid to be condensed, the materials would then have to be adapted if necessary in order to be resistant to corrosion.

It makes sense for the cooling chamber and the engine room to be smaller than the interior dimensions of the container so that they can be walked on and/or serviced easily.

Furthermore, the individual elements of the device according to the invention are fixed at their respective location, in particular releasably fixed (which facilitates repair and/or maintenance), for example by means of screws and/or snap or bolt closures. This fixation is a further feature that enables the device according to the invention to be shipped and thus transported quickly to any location.

In preferred embodiments of the present invention, the device produces approximately 7.5 kW/h of electricity, in particular 7.35 kW/h, thanks to the photovoltaic used. In preferred variants, this current is used to operate the entire internal technology, so that the device according to the invention is electrically self-sufficient.

In a preferred variant of the present invention, this is achieved by arranging 21 photovoltaic modules of 350 watts each on the roof of the housing.

In this respect, the device according to the invention is preferably designed in some variants in such a way that the required electrical energy is generated by the photovoltaic system and excess energy is optionally stored temporarily in the secondary batteries. The secondary batteries can be connected to the photovoltaic battery via a charging current unit.

The photovoltaic system of the device according to the invention makes it possible to work independently of an external power supply, since the photovoltaic elements are able to convert sunlight into electricity and charge the secondary batteries during the day. The device can then be supplied with electrical energy from these secondary batteries during night-time operation.

The device of the present invention enables quick and easy transport and offers a robust protection of the technology, in that standardized containers, such as in particular 40-foot containers, are used as the housing.

Another advantage of the device of the present invention is that it can be used quickly at a wide variety of locations in the world due to the good transportability (because of the standardized containers). It is also particularly advantageous that the devices of the present invention are sustainable in use and cause as little harm to the environment as possible because they can be operated without external power sources thanks to the use of photovoltaics and cause no emissions during operation (except for dehumidified air and (reclaimed) condensate).

Another advantage of the present invention is that at least one reservoir for the mineralized water produced is already included within the device. As a result, generated water can be stored in the device, which removes it from the influence of harmful environmental influences (germs, dirt, etc.).

Another advantage of the present invention is that due to the use of standardized components such as shipping containers, known cooling elements or other known and available units, the devices according to the invention can be produced relatively inexpensively and are also comparatively easy to maintain, since, for example, corresponding spare parts are readily available are.

In this respect, the devices of the present invention differ from the prior art, among other things, in that water can be generated and stored in an electrically self-sufficient container housing that can be shipped worldwide using standard logistics systems. Such a combination was not known from the prior art and could not be derived.

In model calculations for the application of the device according to the invention, it was determined that considerable amounts of water can be obtained.

For example, for the town of Chegga in Mauritania, with a humidity of 10% and an average temperature of 35° C., there is an expected water gain of approximately 11 liters per hour when the device according to the invention is operated during the day.

Furthermore, for the location of Pedro Juan Caballero in Paraguay, with a humidity of 80% and an average temperature of 30°C, an expected water gain of 95 liters per hour during the day and 45 liters per hour at night.

The invention is explained in more detail below with reference to the figure. The figure is not true to scale and is simplified. Thus, usual measures etc. familiar to the person skilled in the art are not necessarily shown (for example pipes, screw connections, cabling etc.) in order to make the figure easier to read.

1 shows a longitudinal section through a device according to the invention for obtaining drinking water in a schematic representation. It can be seen there how air enters the device from the left side, illustrated by the solid arrows. This takes place in that this air is sucked in by the ventilation unit 6 . The aspirated air immediately enters the first filtration unit 2, where it is cleaned of impurities such as sand or pollen etc. that have been carried along. The filtered air then enters the cooling chamber K via a line 10, which can in particular be a pipe or a hose. In this cooling chamber K there is at least one cooling element 9, which is shown in this figure as an elongate element with six protuberances projecting downwards, for example in the form of ribs or cold fingers. In addition, there is a water collection unit 7 below the cooling element, which serves to collect the condensed water that drips down. The water collected in the water collection unit 7 can either be fed directly into the next unit, the second filtration unit 3, via a line for condensed water 13, which is optional (the water collection unit 7 can also be connected directly to the following unit). There, the condensed water is cleaned of contaminants such as microorganisms or pollen or suspended matter that have been carried along. This second filtration unit 3 can include a water treatment unit such as an ozone generator or a UV irradiation unit. Following this second filtration unit, optionally also integrated with it, is a water treatment unit that includes at least one mineralization unit. In addition to or as an alternative to the second filtration unit 3, this water treatment unit can include a water sterilization unit, for example an ozone generator or a UV irradiation unit. The water treated in this way then reaches a water reservoir 5. The water stored here in the water reservoir 5 is correspondingly mineralized. It is also possible, although not shown in this way in the drawing, for the water reservoir 5 and water treatment unit 4, in particular the mineralization unit, and possibly even the filtration unit, to be designed as one component. In this case the mineralization could take place directly in the water reservoir. continue in 1 a water discharge line 11 is shown, including a water extraction element represented by the arrow. This water discharge line 11 is in particular a pipe or hose with a water tap or water connection at the end, with the water tap or water connection preferably being standardized within the scope of the present invention (e.g. DIN) in order to be able to ensure simple connectivity with on-site connections or connections . In 1 is also shown in the upper part how the flow of cooled air (whose moisture content is reduced) exiting the cooling chamber is discharged and via lines 10, which are preferably hoses or pipelines, either directly to the outside, in order then, for example, to attached or connected premises (such as hospitals, schools or the like) to be routed or - alternatively or additionally - to the right in the picture shown via the machine room M or through the machine room M, in order to cool it and only then be led out of the housing of the device according to the invention and made available with appropriate connections or with associated premises.

In addition, 1 still illustrated that photovoltaic elements 8 are arranged on the roof of the housing. For the sake of simplicity, in 1 only three of these elements are shown, but this can also be any number of more elements, in a preferred embodiment, for example, these are 21 elements each with 350 watts.

The various embodiments of the present invention, e.g. - but not exclusively - those of the various dependent claims can be combined with one another in any manner, even if these combinations are not explicitly mentioned, provided that such combinations do not contradict one another.
