Definitions
- Water is a building material in photosynthesis of plants and part of organisms
- water is solvent, means of transport and swelling agent. It allows the numerous chemical and colloid chemical cell reactions.
- Water is not just a hydrophilic reaction space, plastic - elastic filler, heat storage and cold storage. It is also a compound with memory properties and has interesting interactions with electromagnetic waves and sound waves.
- the total water volume of the earth is estimated at about 1383 million cubic kilometers. These are mainly salt water. Only the vanishingly small remainder of 2.6% is accounted for by the fresh water. As fresh water while water is called less than 1 gram evaporation residue. If one subtracts from this amount the hard-to-reach polar ice, glacial ice and the very low groundwater, it follows that for humans, animals and plants, only about 8% of the available fresh water can be used directly.
- Decisive regulative for the preservation of the fresh water stock is the water cycle of the nature. This consists of the processes of water evaporation, precipitation, runoff and subsequent re-evaporation. From the balance of the global water cycle of the earth, it is clear that in the same time periods a larger amount of water evaporates on the oceans than is precipitated by precipitation. On the land areas, however, the situation is reversed.
- the uneven distribution of rainfall on earth is one of the largest
- One method consists in principle of allowing the water contained in the air to condense on a horizontally stretched film and lowered at one point, and to allow it to drop into a container placed underneath. In this way, however, only very small amounts of water can be obtained.
- the basic principle used here is to allow the available air to pass past a cool surface, thereby cooling it and thereby forcing it to release parts of the water bound in the air. Because air at a certain temperature can only store a certain amount of water as humidity. When this amount is reached, the air is saturated with water vapor. If the air is subsequently cooled, it can only store a smaller amount of water vapor. Excess water in this way can no longer be held by the air and precipitates, it condenses. This happens in that the excess water vapor precipitates on cooler surfaces, compacts into droplets, and follows the force of gravity.
- this working principle is used by ensuring on the one hand that as much air as possible passes by on a surface which is cooler than the instantaneous air temperature, and that the corresponding surface is made as large as possible.
- Such a device with which heat or cold is transferred from one medium to another, is called a heat exchanger.
- This is essentially a heat exchanger with a longitudinally flowed through by a gaseous medium housing with a plurality of arranged in the housing longitudinal direction and flowed through by a coolant heat exchanger tubes.
- the heat exchanger tubes are designed as helical pipe strands and the pipe strands are coolant inlet side and coolant outlet connected to coolant manifold with coolant inlet and coolant outlet.
- the installation position is particularly important in the heat exchanger according to the invention.
- Another important aspect of the heat exchanger according to the invention is that the flow direction of the coolant opposite to the flow direction of the
- Air flow is directed.
- the coating of the heat exchanger tubes according to the so-called lotus effect additionally provides a higher water yield.
- Fig.1 the side of the coolant inlet Fig.2 the side of the coolant outlet Fig.3 a longitudinal section
- Fig. 1 is in a plan view of the heat exchanger according to the invention, the side of the air outlet with the (1) designated distributor ring for the coolant inlet to recognize.
- the water outlet (19), which can be seen from Figure 3, is omitted.
- the coolant enters in this case from the opposite side shown in Fig. 2, and is connected via a pipe which extends in the central axis of the heat exchanger, and via a subsequent radially extending supply pipe, as shown in Figure 1, in the
- Coolant distributor ring (1) passed.
- the plan view shows the lower coolant inlet nozzles (2) in the lower one
- the middle coolant inlet nozzles (4) can be seen analogously in the middle of the picture.
- the lower nozzles (2) have a larger cross-section than the upper nozzles (3), since the risk of icing in the lower evaporation region is greater than in the upper region of the heat exchanger.
- the middle nozzles (4) have a central cross-section.
- Cross-section of the heat exchanger according to the invention results in a uniform cooling of the air carried out.
- the entire water production plant can be driven specifically at the border to icing.

- Fig. 2 shows a plan view of the heat exchanger according to the invention of the
- Coolant outlet as the direction of the air inlet and the direction of the
- Coolant flow are opposite. With (9) here the coolant outlet line is designated, which opens into a, the cross-section after extended, coolant outlet nozzle (10). At a right angle thereto, the coolant inlet line (8) can be seen, which, concealed in the representation, in the central axis of the heat exchanger to the other, shown in Figure 1 side, tapers.
- coolant outlet connections are designated by way of example in FIG. They establish the connection of the evaporator coils (6) with the, in this area circular, coolant outlet line (9).
- coolant outlet line 9
- helical high-pressure cleaning line With (12) here the inlet nozzle of this line is marked, with (11) are some of the cleaning nozzles named. From these nozzles (11) is sprayed at certain time intervals under high pressure, a special cleaning liquid. Again, the evaporator coils (6), this time from the other side of the heat exchanger, can be seen again.
- the air flow is caused by an air flow generator (20), which may be designed as a fan or as a compressor or as a turbine. When running as
- Compressors are piston compressors or screw compressors in question.
- the water separator (18) consists essentially of obliquely arranged
- the inclination of these slats can, according to the speed of the
- Air flow be designed changeable. According to the invention, all components which are flown by the working air have a coating which causes the lotus effect known from plants.
- the lotus effect is named after the lotus flower, which is considered a symbol of purity in Asian religions. Their leaves unfold impeccably clean from the mud of the waters. This phenomenon of self-purification has been studied and provides amazing insights into the possibilities of nature to defend against the ubiquitous dirt, but also against microorganisms. Since the lotus effect is based solely on a physico-chemical basis, and is not bound to a living system, a self-cleaning surface can be manufactured technically. The materials for such new coatings are available. To date, however, the seemingly contradictory demand for a rough surface has been overlooked as the basis for a clean surface as a result of the lotus effect.
