Definitions
- the present invention relates to a process for obtaining water from a mass of atmospheric air and machine for obtaining water by condensing moisture from a mass of air.
- Any mass of natural air is moist, that is, it contains an amount of water vapor.
- Said water is likely to be recovered if its separation from the rest of gases and air components is achieved.
- the process of the invention proposes this separation by changing the gas phase to a liquid or solid phase, while the rest of the gases in the air maintain precisely their gas phase.
- the process of the invention serves in an optimal way to obtain water from a mass of moist air, being able to take advantage of this, and particularly, any atmospheric mass.
- the process comprises the following steps:
- This precooling decreases the energy requirements of subsequent cooling. It can be carried out with conventional refrigeration machines or, more preferably, by natural means, such as by using heat exchangers the lower temperature than the incoming air, of a nearby or similar water channel.
- the residual cold of artificially cooled water can also be used for other uses, for example, from a hospital water chiller.
- the final cooling will be carried out by the evaporator, and the flow of already dried and outgoing air will be circulated of the primary of the air-air exchanger by the condenser of the cold machine, taking advantage of its residual cold to cooperate in the condensation of the refrigerant gas of the machine, increasing the performance of the energies used in the process.
- the indoor air flow In case the temperature of the outside incoming air flow is high, in hot environments, the indoor air flow, after its exit from the air-air exchanger and before its impact on the condenser, It will be mixed with an external air supply to cool the heat generated in it, equivalent to the sum of the evaporator (taken from the incoming air flow) plus the equivalent to the compressor consumption, also carried by the refrigerant gas.
- a machine that comprises an enclosure, with an obvious frame, in which an intake and an outlet of a humid air flow generated by the operation of one or more turbines or internal fans are arranged .
- a cold equipment ideally conventional based on compressor, evaporator and condenser, although it can also be an exchanger that takes advantage of the lowest temperature existing in other media, for example liquids (a stream of water, a flow of water cooled by a machine, etc.).
- the cold equipment must be able to lower the temperature of the incoming air flow continuously below the dew point to cause condensation and precipitation of water, which will be collected by a tank and bottom collector.
- the cold equipment will be conveniently sized to produce this cooling, but ideally without lowering the temperature below 0 0 C, which would result in the freezing of water and its most inconvenient collection.
- the enclosure includes an air-to-air exchanger, on one of whose paths the cooled and dehydrated air circulates, while on the other the incoming air flow circulates through the intake intake, so that part of the cold of the outflow It will take advantage of producing a precooling of the incoming flow, improving performance.
- the cold equipment will be inserted in the air flow circulation path between the two exchanger tracks.
- the evaporator will be inserted in the circulation of the flow between the two routes of the exchanger, producing the final cooling of the air mass and consequent condensation of the water, while the condenser will be arranged the exit of the second way of the Exchanger, corresponding to the already dehydrated air, in order to take advantage of its residual cold to favor the condensation of the refrigerant gas and increase the efficiency even more.
- a secondary intake of outside air may be available at the outlet of the flow recuperator and, prior to the passage through the condenser, so that, in the event that the temperature of the incoming outside air is high, in hot environments, this extra flow Incoming by the secondary outlet cooperate in evacuating the heat generated in the condenser, equivalent to the heat absorbed by the evaporator of the incoming air flow plus the energy consumed by the compressor.
- FIG 1 schematically shows the process of the invention.
- FIGS 2 and 3 schematically show the process of the invention with two improvements.
- FIGS 4 and 5 show different variants of the machine of the invention. DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION
- the process of the invention comprises the steps of: Generating a flow 1 of air from the mass whose moisture is to be extracted.
- the flow can be generated artificially, or natural air currents can be used.
- the cooling is generated by a thermal machine 4 consisting of any suitable known refrigeration system.
- - Collect the condensed water by means of manifolds 5.
- - Recirculate the outgoing flow 6 of cooled and dried air through the primary 7 of the exchanger 3, obtaining in the secondary 2 the precooling of the incoming flow 1 described in the second stage, and reducing the consumption energy of the thermal machine 4 at the time of achieving the definitive cooling.
- the thermal machine for example may consist of an exchanger 15, as seen in Figure 2, or a conventional refrigeration machine based on a compressor, evaporator and condenser, as seen in Figure 3.
- the machine that implements the process of the invention, and which is represented in Figures 4 and 5, it comprises an enclosure 16 in which an air intake 17 is provided that first passes through the first path of the internal air-air exchanger, constituted in this non-limiting example of the invention by a cross flow recuperator 18, in order to be precooled, and then passes through the internal evaporator unit 4a of a conventional cold equipment, which will cause its temperature to fall below the dew point, which will cause the liquid phase of the water it contains to change.
- the cold equipment will be adequately sized so that the possible temperature does not fall below 0 0 C to avoid changing the water phase to a solid phase.
- the air flow will circulate in the second path of the cross flow recuperator 18, so that it will give up some of its cold to produce the pre-cooling of the incoming mass.
- the machine then disposes the condensing unit 19 of the cold equipment, so that the residual cold of the outgoing dehydrated air flow will be used to improve the performance of this part of the machine, and will increase its temperature while minimizing the environmental impact when expelled by the air outlet.
- the machine has the turbine or turbines 20 that generate the flow, adjacent to the air outlet 21.
- the cold equipment implements the obvious compressor 9. If it is desired to further increase the effectiveness of the machine, the incoming air flow can be subjected to additional precooling by external means or equipment 14, such as a cooling equipment external, an external exchanger that takes advantage of the temperature of a nearby water flow, of a water cooling machine or similar.
- external means or equipment 14 such as a cooling equipment external, an external exchanger that takes advantage of the temperature of a nearby water flow, of a water cooling machine or similar.
- a tank capable of being connected to an outlet manifold 5.
- the conventional cooling equipment is replaced by a single air-water exchanger 23, which will cool the air thanks to the lower temperature of a water flow, which may come, for example, from a hospital water chiller, be a natural channel, or have any other origin.
- any means or equipment capable of lowering the air flow temperature sufficiently can be used to produce cooling.
