Definitions

  • the invention relates in its various aspects to apparatus and methods for extracting water from air, collecting water and maintaining a supply of potable water.
  • the invention is particularly relevant to a machine for generating and dispensing potable water from humid air.
  • Bangladesh is a country with relatively warm climate and highly humid air. Bangladesh has a plentiful supply of water in terms of river water, but this river water is often contaminated and not suitable for drinking. During the regular floods that occur in Bangladesh, safe drinking supplies may become unavailable or quickly contaminated and many people become ill or die from the results of drinking contaminated water. If machines could be deployed to successfully extract drinking water from the humid air, then lives could be saved in times of natural disaster. In practice, the production of an air to water generating machine for producing and maintaining water for human consumption has proved difficult. Problems exist in the extraction of a sufficient volume of water and in the extraction of water at an economical rate per watt of energy used. Furthermore, particular problems exist in the purification of generated water and the maintenance of potable water. Existing systems quickly succumb to the contamination of water within the machine by bio-slime and black moulds that render the water unpalatable or unsafe for human consumption.
  • the invention may provide an apparatus for extracting water from air comprising a housing defining a cavity having an air inlet and air outlet, a condenser disposed within the cavity between the inlet and the outlet (such that air passing through the inlet through the cavity and out of the outlet passes across the condenser). At least a portion of the surface of the condenser comprises a hydrophilic material.
  • the hydrophilic material could be material making up the condenser itself or could be a material coated onto the surface of the condenser.
  • the condenser comprises cooling fins that are corrugated or otherwise shaped to increase the surface area of fin, for example "s-fins".
  • fins there may be one or more fins on the condenser and one or more condensers mounted in the cavity, depending on, among other factors, the volume of air to be passed through the cavity and the amount of cooling required. Any known method of cooling the condenser could be used.
  • the condenser may advantageously be cooled by a pettier cooling means or by a refrigerant gas cooling system.
  • the apparatus further comprises a filter spanning the air inlet and a filter spanning the air outlet.
  • the apparatus comprises means for causing air to flow through the cavity, i.e. to flow from the external environment in through the inlet, across the surface of the condenser, and out of the outlet.
  • the apparatus may comprise a single filter for filtering efficiently different sizes of airborne particles.
  • a single filter that accomplishes the filtering efficiently of different size particles may advantageously make the inlet filter simpler and cheaper to exchange when this is required.
  • a fan may be mounted within the housing where it can act to draw air through the inlet and over the condenser, and drive air out of the apparatus through the air outlet.
  • the means for moving air may produce a fixed rate of air flow over the condenser.
  • the rate of flow could be set, for example, to produce the optimum amount of condensed water for a particular set of environmental conditions (e.g. air temperature, air humidity, condenser temperature).
  • the means for moving air e.g. a fan
  • the apparatus may comprise a sensor or sensors for monitoring one or more environmental or apparatus parameters.
  • the apparatus may also comprise a controller coupled to the sensor for providing feedback to the air moving means to vary the air flow rate through the apparatus.
  • a similar feedback system as described above in relation to varying airflow over the condenser could be used to vary the temperature of the condenser in response to changes in certain parameters.
  • both the air flow rate and the condenser temperature can be varied in response to environmental conditions with the aim of producing an optimal yield of water or, alternatively, producing water using minimal power.
  • the cavity comprises an opening for the passage of condensed water away from the condenser.
  • This opening is preferably situated, in use, below the condenser.
  • water condensed on the condenser may drip down under the action of gravity and into the opening to be carried away.
  • a collection tray or funnel may be fitted into such an opening to aid the collection of condensed water.
  • the invention may provide an apparatus for collecting and purifying water.
  • This apparatus may comprise a collection member for receiving water, such as a funnel or a tray, in which at least a portion of the collection surface of the collection member comprises a material having biocidal and/or antimicrobial properties.
  • a collection member for receiving water such as a funnel or a tray
  • at least a portion of the collection surface of the collection member comprises a material having biocidal and/or antimicrobial properties.
  • water entering the collection member may contact biocidal or antimicrobial material and thus any bacterial or microbes within the water at this stage may be neutralised.
  • the apparatus further comprises a conduit for the passage of received water leading away from the collection member towards a non-return valve.
  • a water filter is disposed in-line in the conduit between the collection member and the non-return valve, and the apparatus further comprises a pump for transporting water from the collection member through the non-return valve.
  • water In use, as water is transported from the collection member it is passed through the water filter and then through the non-return valve. As the water passes through the water filter remaining particles, or particles that have originated within the water machine, may be removed leaving pure water. The water may then simply be dispensed via the non-return valve, for example for use in irrigation or in industry, or may pass into a further portion of the apparatus or a further apparatus for storage.
  • the water filter preferably contains carbon and may contain or include antimicrobial or anti-bacterial material, for example silver.
  • the conduit is made of a flexible material, for example a silicone rubber pipe or tubing, and preferably the pump is a peristaltic pump that acts on the flexible conduit.
  • the pump is a peristaltic pump that acts on the flexible conduit.
  • a preferable material for use as the biocidal/antimicrobial material is silver. Silver is commonly available and can be easily coated onto the surface of a collection member.
  • the water filter is preferably a carbon filter for removing particulate matter from the water.
  • the invention may provide an apparatus for purifying and dispensing water, preferably potable water.
  • This apparatus may comprise a purification zone for purifying water, a dispensing zone for storing and dispensing water, and a circulation system for producing a continuous circulation of water between the purification zone and the dispensing zone.
  • Any system which has standing water runs the risk of the growth of bio-slime. This is a growth of bacteria which, whilst it may not be hazardous to health in all cases, can add an unpalatable taste to the water.
  • a system with standing water also encourages the growth of black mould which makes the water unsafe. If the water is always moving, i.e. if it is not allowed to settle and stagnate, then the risk of the growth of bio-slime and black mould is reduced.
  • the purification zone may comprise an antibacterial means such as an ultraviolet radiation source for radiating water with ultraviolet light or any other suitable means of purification
  • the purification zone comprises an ozonation device or ozonation chamber. This type of device generates ozone gas, which can be bubbled through the water. A proportion of the ozone is absorbed into the water and acts as an anti-bacterial agent.
  • a preferable ozonation device comprises a chamber having a water inlet and a water outlet.
  • This chamber houses a proton exchange membrane (PEM) cell for generating bubbles of ozone within the chamber.
  • PEM proton exchange membrane
  • Ozone generated in this way is absorbed into the water and acts to kill bacteria and microbes.
  • the amount of ozone absorbed into the water is related to the surface area of bubbles generated by the PEM cell; a small number of large bubbles produce a lower area of gas - liquid interface per volume of ozone than a large number of small bubbles. Therefore a preferable ozonation device has a mesh, for example a stainless steel mesh, arranged so that bubbles generated by the PEM cell are disrupted by the mesh.
  • the ozonation device or the apparatus contains some indicator or switch for determining whether there is sufficient water in the system for the PEM cell to be operated.
  • the PEM cell may suffer damage if operated without being immersed in water, thus the apparatus must either be primed or, if incorporated as part of a water generation machine, the machine is preferably operated for a period of a few minutes prior to operating the ozonation device.
  • a sensor of some type acts to detect the presence of water at the PEM cell before the ozonation device is allowed to operate.
  • the dispensing zone comprises a storage tank having a water inlet for receiving water from the purification zone, a water outlet for returning water to the purification zone, and a dispenser for dispensing water from the tank, for example for drinking.
  • the dispensed water may be treated in some way to improve the taste of the water.
  • flavourings, essential minerals and salts could be added within the storage tank or within the circulation system. (Such treatments may also be added to the water at an earlier stage in processing).
  • Water may be carbonated before, or during, dispensing. If this is desired a standard carbonation unit could be suitably arranged within the apparatus.
  • the storage tank is shaped such that, in use, there are no horizontal surfaces. This may help, in combination with the water circulation system, prevent the formation of standing or stagnating water.
  • the tank may have sloping curved sides leading down to a low point at which a water outlet for returning water is situated. Water in the tank is continuously flowing through the outlet at the lowest point of the tank and is, thus, not allowed to become stationary within the tank, but is continually moving.
  • the storage tank may include a switch to cease production when the tank is full.
  • the storage tank may be light-tight, so as to inhibit the formation of algal growth.
  • the storage tank may incorporate a float switch, or some other means for determining water level or volume within the storage tank.
  • the advantage of such means is that the output of the ozonation cell may be tailored to increase with increasing volume in the system. This may allow the volume of ozone produced per volume of water to be maintained as an approximate constant.
  • the storage tank may also incorporate some visual means for determining water level, for example a window or a light emitting diode (LED) display. It is preferable that the storage tank and circulation system do not contain any materials that react with ozone where a level of ozone is to be maintained in the water.

  • the apparatus may further comprise a chiller element arranged to cool water so that cooled water may be dispensed.
  • the chiller may be arranged within the circulation system prior to water entering the tank or the dispensing zone, such that the dispensing zone is filled with cooled water, or alternatively the chiller may be situated downstream from a dispenser associated with the dispensing zone so that only dispensed water is cooled.
  • the circulation system may include a filter, for example a carbon filter. Water within the circulation system would then continually pass through the filter and this may help neutralise any bacterial growth.
  • a filter may contain an anti- microbial or anti-bacterial agent, for example silver. Silver particles may oxidize within the system, particularly if ozone is present, however, silver oxide may still provide beneficial antibacterial effects.

  • water vapour carried by the air is caused to condense into liquid water at the condenser, which is maintained at a lower temperature than the air.
  • the condenser 40 is coated with a hydrophilic lacquer (comital lacquer (ATS)dian) which interacts with condensation of atmospheric humidity on the condenser causing an increased superficial tension creating a thin surface liquid film of uniformly spaced microscopic drops instead of the usual coarse drop aggregation, thus improving the thermo-unit efficiency.
