Definitions

  • This invention relates to the generation of potable water by recovering liquid water from the humidity of environmental air.
  • the invention primarily relates to apparatus for generating and then dispensing such potable water.
  • US patent 5,106,512 describes a water generating device having a fan for moving air over a condensing unit (evaporator coils), a collection point to catch water falling off the condensing unit, a water reservoir and various treatment options.
  • the device is a single location unit and the patent primarily relates to a single use filter element, and its configuration, as illustrated in its Figures 3 and 4.
  • US patent 6,588,226 describes a water recovery and dispensing system for use in situations of low temperatures and/or low humidities, where there is either a low water vapour level (and thus little water to condense from the air) or a where there is a potentially small temperature differential and thus more difficult dew point temperatures to deal with.
  • the system described also uses a fan to move air over a condensing unit (again, evaporator coils), but with a control system that permits and, indeed, promotes the build up of ice on thereon.
  • the present invention provides an apparatus for generating potable water from moisture-laden air, the apparatus including:
  • the water generator includes a means for cooling the purified incoming moisture-laden air to below its dew point to condense moisture and form water droplets upon a collector, and a vibrating means capable of at least intermittently vibrating the collector to remove condensed water droplets therefrom.
  • the incoming air purifying means may include one or more suitable air purification stages.
  • the incoming air purifying means includes a mesh filter that is fine enough to prevent the ingress of insects, together with an electrostatic filter, through which the incoming moisture-laden air will pass for purification and removal of, ideally, dust, pollen, mould, dust mites and other indoor pollutants.
  • the apparatus of the present invention must include a water generator that is capable of condensing liquid water from the purified moisture-laden air.
  • the liquid water is condensed from the moisture-laden air by the lowering of the temperature of the air to a temperature below its dew point, thereby causing at least a portion of the water vapour in the air to condense into water droplets, ideally upon a droplet collector.
  • a cooling means located within a flow of the incoming purified but moisture-laden air.
  • the cooling means may be any known cooling mechanism or device, but will preferably include the normal elements of a refrigerating cycle, which will now be described.
  • the cooling means will preferably include a compressor, an evaporator and a condenser, with these elements being configured for maximum contact of the flow of incoming purified, moisture-laden air with at least the evaporator (being the cooling element of the cooling means), such that water droplets condense from the incoming air on the surface of the evaporator, the evaporator thus being the droplet collector.
  • the configuration of the different elements of the cooling means is also such that the cooled air subsequently flows over and about both the condenser and the compressor (which are usually operating at higher temperatures) to lower their temperatures and assist in maintaining lower operating temperatures for the entire apparatus.
  • the evaporator and the condenser are preferably both coiled elements, having a predetermined number of coils, optimized to maximize the rate of water generation.
  • an ideal ratio of the available heat transfer area of evaporator coils to condenser coils is in the range of from about 1 :1.35 to about 1 :1.60, and is preferably in the range of from 1 :1.40 to 1 :1.55. Most preferably, the ratio is about 1 :1.45. In very general terms, this means that an ideal arrangement has been found to be one that provides, for every two evaporator coils (or rows of evaporator coils), three condenser coils (or rows of condenser coils).
  • evaporator coils and condenser coils formed from spiral (twisted) tubes which, in terms of water generation in the apparatus of the present invention, provide a greater heat exchange efficiency due to the substantially higher available heat transfer area that arises as a result of the fin- like spirals, and thus further increase the water generation rate.
  • the cooling means it is envisaged that there will be some atmospheric conditions that are not conducive to water generation in this manner, such as when the ambient air temperature and/or the humidity levels are low, and thus the dew point temperature is low. Therefore, in one form of the invention there will preferably be provided an incoming air pre-heater. Ideally, the pre-heater will rely on heat generated within the apparatus as its source for energy.
  • the condenser coils will operate at relatively high surface temperatures (such as from about 55 0 C to 6O 0 C), so outgoing air that passes over and about the condenser coils will be heated and may then be useful in pre-heating the incoming air.
  • the water generator may be provided with a return air line that is capable of receiving hot outgoing air and channeling it back through the stream of cooler incoming air (without mixing the streams) to thereby heat the incoming air, raising its dew point. This may be achieved by the use of copper tubes as the return air line, with the returned air simply being exhausted to atmosphere upon completion.
  • a vibrating means capable of at least intermittently vibrating the collector to remove condensed water droplets therefrom.
  • the collector will be the evaporator coils that are provided as a part of the cooling means.
  • the vibrating means will thus be configured so as to at least intermittently vibrate the evaporator coils, or at least that region of the evaporator coils where the majority of the droplets are forming.
  • the vibration of the evaporator coils will be triggered once enough water has gathered, and thereafter at every 3 to 7 minutes of operation (preferably at about 5 minutes), and the vibration will be effected for periods of from 5 to 90 seconds (preferably for about 20 seconds). It has been found that this results in an increase in water generation in the order of about 20 to 25%, compared to the same system without the vibrating means.
  • the vibrating means is an electric motor with an eccentric rotor, configured and controlled such that the motor is rigidly secured to at least the evaporator.
  • the operation of the motor rotates the eccentric rotor, causing vibration of the evaporator.
  • the evaporator will therefore ideally be suitable mounted within the apparatus so as to permit its vibration, without damaging other parts of the water generating apparatus.
  • the water generator itself may, as a unit, be configures so as to be inclined to the horizontal. In this respect, it is envisaged that only a relatively small inclination will be needed for some assistance to be provided. Preferably, the inclination will be such that the base of the water generator is inclined in the order of 5 to the horizontal.
  • the water generating apparatus of the present invention also includes a water storage means capable of receiving from the collector, and then storing, the condensed water.
  • the water storage means may thus include a diverter of some type, such as a funnel, for catching and directing the condensed water to one or more storage tanks.
  • Suitable control devices will ideally be utilized with such storage tanks to provide warnings for empty or full conditions, to thus trigger operation (or not) of the water generating function, or to trigger operation of flow valving (or the like) from one storage tank to another, or to trigger operation of flow valving (or the like) to one or more local or remote dispensers.
  • each storage tank preferably includes a stirring device to ensure that water stored therein does not remain stagnant.
  • water collected and stored in a water storage means is constantly treated by an ultraviolet purifier providing non-chemical disinfection of the stored water.
  • the ultraviolet purifier may be in the form of a germicidal ultraviolet lamp.
  • this treatment means is a multiple stage treatment process, utilizing different treatment technologies as will now be described.
  • the treatment means may be provided near the other elements of the apparatus described above, or may be provided remotely of these other elements.
  • the stored water preferably passes through at least a four stage treatment process before being dispensed as potable water, as follows: a) a sediment filter for removing sediment particles such as dirt and sand down to a nominal micron particle size; b) a pre-carbon filter for absorbing harmful organic chemicals such as chlorine, volatile organics and trace pesticides/insecticides; c) an ultrafine membrane filter for removing water contaminants such as micro-organisms; and d) a post-carbon filter for further absorbing harmful organic chemicals and to assist with removal of bad taste and odours.

  • the treatment means may also include other treatment stages such as a mineraliser, an ioniser and an oxygenator. Further, one of the above treatment stages may be replaced with a water activator module to produce, for example, activated water (or, water with an altered molecular resonance).
  • the present invention envisages the adoption of a distribution system, allowing there to be multiple dispensers located either on the water generating apparatus or remote of the water generating apparatus.
  • the distribution system may also permit the tapping of water from sources other than the apparatus of the invention, such as from mains water supplies or rain water tanks.

  • FIG. 1a and 1b Illustrated in Figures 1a and 1b is a water generating and distributing unit 10 that is made up of different parts and is configured so as to be a central unit connectable to multiple water dispensers (not shown).
  • the unit 10 is preferably free-standing and reasonably mobile, and includes the water generating apparatus 12, a main controller box 14 and a pre-dispenser treatment apparatus 16.
  • the pre-dispenser treatment apparatus 16 it should be noted that this, in the broadest form of the invention, forms a notional part of the water generating apparatus 12, as referred to above as the treating means.
  • an air outlet 24 At the rear of the unit 10, (visible in Figure 1a) is an air outlet 24, a water outlet 26 for transferring water generated by the water generating apparatus 12 to the water inlet 28 of the pre-dispenser treatment apparatus 16, and a water outlet
  • the fluid connections between various of the parts of the unit 10 may be configured internally (rather than externally) of the casing of the unit 10. Also, the order of the vertical arrangement of the parts may be altered as necessary. Further, the unit 10 may provide more than four water outlets for four dispensers, and may indeed include integral (rather than remote) dispensers.
  • Figure 2 provides a general flow diagram for the embodiment of the unit shown in Figures 1a and 1b.
  • the incoming moisture-laden air 50 enters the water generating apparatus 12 while the outgoing air 52 exits having had most moisture removed therefrom.
  • the water generated passes via lines 60, 62, 64, 66, 68 and 70 through the pre-dispenser treatment apparatus 16 and the controller box 14, to respective dispensers 72, 74, 76 and 78.
  • the dispensers themselves may be configured and designed so as to be capable of dispensing hot or cold water, even though in this embodiment the water is only delivered to them at a single temperature.
  • an additional water source 54 may also be plumbed into the unit 10 if considered necessary or desirable.
  • the water generating apparatus 12 includes means for purifying the incoming moisture-laden air, in the form of a mesh filter 100.
  • a water generator in the form of a cooling means having a condenser 102 in connected in a normal refrigeration cycle with an evaporator 104, a compressor 106 and a pump 108, includes a fan 110 located between the condenser 102 and the evaporator 104.
  • the fan 110 draws incoming moisture-laden air through the casing air inlet 18, through the mesh filter 100, across the evaporator 104 during which the air cools to below its dew point and then across the condenser 102 during which the air is re-heated, to exit the apparatus as heated, outgoing air via air outlets 24.
  • the mesh filter 100 includes an electrostatic fitter for ionizing the incoming air as a preliminary step.
  • the mesh filter 100 and the electrostatic filter may be any known type of such filters.
  • the water generator also includes a means for pre-heating, if deemed necessary due to the atmospheric conditions, the incoming moisture-laden air.
  • the pre-heating means is provided by a return-air line 103 configured so as to have an inlet end 105 arranged to be in a concentrated stream of heated, outgoing air provided by concentrator 107.
  • the heated, outgoing air passes around the return-air line 103 in front of the incoming air filter 100 to pre-heat the incoming air, before being expelled through the outlet end 109 with the exhaust air.
  • pre-heating means When such a pre-heating means is provided, together with suitable temperature sensors associated with the evaporator coils 104 and the incoming air, where there is a temperature differential of less than about 6 0 C (and thus the conditions are not conducive to efficient water generation under normal humidity conditions), it is beneficial to operate with the pre-heating means to raise the temperature of the incoming air and thus raise the temperature differential. However, if the temperature differential moves above about 1O 0 C (which will typically be deleterious to water generation under normal humidity conditions) the pre-heating means is not needed. Ideally, the operation or nor of the pre ⁇ heating means is affected by a valve able to open and close the inlet end 105.
  • the apparatus is preferably provided with additional controls such that, for instance, if the temperature differential cannot be raised above 6 0 C (even with the pre-heating means operations), the entire unit is switched off.
  • the liquid water in the moisture-laden incoming air is condensed upon the external surface of the evaporator coils 104 (which thus act as a collector) by the lowering of the temperature of the air to a temperature below its dew point. This is effected as the incoming air contacts the cooled surface of the evaporator coils.
  • the storage chamber will include a suitable stirrer (not shown), to prevent the stored water stagnating, the control of which will be described below.

Indeed, even an inclination of 5° (achieved by inclining the base of the water generator an amount of 5° to the horizontal, as is shown in Figure 5) may assist in increasing the available contact area and/or droplet removal rate of the evaporator coils.
  • the water generator of the water generating apparatus 12 also includes a vibrating means capable of at least intermittently vibrating the collector (in this embodiment, the evaporator coils) to remove water droplets therefrom.
  • the vibrating means is indicated in Figures 3 and 4a by the reference numeral 120 and is shown rigidly attached to the cover 122 immediately above the evaporator 104.
