• a single roll-bond evaporator is shown in Figure 2a showing the arrangement in one preferred embodiment of liquid coolant conduits 22a.
• Conduits 22a may thus in one embodiment be arranged so as to extend vertically along substantially the entire height dimension of the roll-bond evaporator 20.

Inducted airflow in direction A is drawn horizontally along a first dimension in direction B through the array of roll-bond evaporators 22 substantially along the entire vertical height of the array.
• the compressor and other corresponding conventional refrigeration components cool the liquid refrigerant, which is then pumped through conduits 22a simultaneously in all of the roll-bond evaporators 22 so that air drawn in the spacing have a second dimensional or width between the evaporators is cooled so as to condense water droplets onto the exterior surfaces 22b of the evaporators without freezing.
• the resulting cooled through-flow air is then drawn through fans 20 so as to exit in direction C.
• the cooled through-flow air is also forced through the core of radiator 14b of refrigeration assembly 14 so that the through-flow of already cooled air from the roll-bond evaporators provides for increased cooling of radiator 14b and thus more efficient operation of the refrigeration cycle.
• radiator 14b for example two radiators 14b, stacked vertically so as to lie in the same plane facing and parallel to the vertically stacked set of fans.
• the set of three fans would have for example two separate radiators 14b, one on top of the other.
• the use of stacked radiators reduced the power consumption by the compressor.
• the present invention thus differs in one respect from the prior art in that whereas in the prior art separate fans are provided to draw air through radiator-style water-condenser units and separate fans are provided for the condenser/radiator of the refrigeration system, in the present invention applicant realized space and energy savings by housing the refrigeration assembly and the water condensing assembly adjacent to one another so as to share the operation of a single fan or set of fans, thereby resulting in increased synergistic efficiency of the system.
• Moisture laden air entering in direction A into the planar spaces 22c interleaved between roll-bond evaporators 22 passes through the spaces in direction B, and exits from spaces 22c as cooled air the cooled air the enters the heated air spaces within the core of radiator 14c wherein the air is warmed as the core is cooled.
• the air passes from radiator 14c as hot air exiting fans 20 in direction C.

• chassis 16 may have approximate dimensions of two meters (91 inches) in height, 1.7 meters (77 inches) in width, 0.9 (41 inches) in depth thus making for a relatively compact water generator.
• chassis 16 thus provides a rigid frame supporting the refrigeration components including the parallel array of roll-bond evaporators 22 held suspended substantially vertically, and the substantially vertical array of fans mounted adjacent the evaporators.
• Sheet-like roll bond evaporators 22 are mounted suspended within chassis 16 parallel to one another.

• Each ratchet and pawl mechanism 26 includes a toothed ratchet.
• the tensioning of lines 28 is controlled by rotation of the ratchet and the operation of a ratchet-engaging pawl.
• Mechanism 26 together comprise an intermittent rotation controller wherein motion from a handle or for example motorized device is converted into intermittent circular motion having a constant rotational direction.
• Mechanism 26 may be released so as to unwind shafts 24 thereby releasing tension on lines 28 by the release of the pawl from the teeth of the ratchet.
• springs 36 are mounted through eyelets 38 in the corners of evaporators 22 so as to tension the evaporators between cross-members 16c of chassis 16.
• Chassis 16 may be mounted on casters 30 or other wheeled or tracked or skid assemblies to allow for ease of positioning.
• Roll-bond evaporators are known in the prior art for use in for example domestic refrigerators. In such refrigerators the sheet of the roll-bond evaporator is typically bent into a U-shape to form a cooling box. Thus the conduits formed in conventional roll- bond evaporators are directed in such a way to allow for bending of the sheet along where the corners of the box are to be formed.
• Roll-bond evaporators are formed by bonding together two thin sheets of aluminium so that the two sheets become a single unitary sheet of aluminium.
• the conduits are formed by masking the desired conduit paths before the two thin sheets are formed together so that, once tiie two sheets are formed into a single unitary sheet the masked path remains thereby separating the two sheets along the length of the masking.
• the remaining separated sheets along the masked path are then further separated so as to define the elongate cavities of the continuous conduits through which refrigerant such as FreonTM may be passed.
• Roll-bond evaporators are thus very efficient as they only present a thin aluminium layer between the refrigerant within the conduits and the air passing over the outer surface of the roll-bond evaporators.
• the roll-bond evaporators are, at least in the illustrated embodiment which is not intended to be limiting, used in a planar form.
• the conduits may be advantageously run the entire length of the sheets without having to worry about where the sheet will be bent.

• the array of roll-bond evaporators when viewed in plan view, that is, from above when seen in horizontal section, forms an array which is approximately square in dimension for example approximately 2 ⁇ ⁇ feet square.
• Another factor in the operation of the atmospheric water generator according to the present invention is controlling the frosting of the roll-bond evaporators so as to minimize and advantageously avoid, the build-up of frost or ice on the surfaces of the roll-bond evaporators.
• One method by which this is accomplished is running the refrigeration assembly at a lower capacity, for example, by reducing the available power from the motor.
• a motor which only delivers approximately 1/16 th of a horsepower per roll-bond evaporator minimizes the formation of frost or ice so as to maximize the formation of moisture droplets on the surfaces of the roll-bond evaporators.
• the surfaces 22b of roll-bond evaporators 22 may be formed with protrusions, or "scales" 42 or other flow-tripping devices such as would be known to those skilled in the art of fluid mechanics, which would rapidly trip a laminar flow into a turbulent one.
• the flow-tripping devices might beneficially be in the shape of sharp edged scales or breaks in the otherwise smooth surfaces 22b of the roll-bond evaporators 22.
• the edges of the aluminium mesh would also provide relatively sharp edges along the aluminium threads or strips forming the mesh.
• the second factor in optimizing the volumetric recovery of water from the atmospheric water generator according to the present invention namely, optimizing the method of removal of water drops from the surfaces of the roll-bond evaporators, in addition to merely relying on gravity to disrupt the surface tension holding a water droplet adhered to the side of a roll-bond evaporator
• applicant has devised several means for accomplishing improved detachment of the water droplets from the surfaces of the roll-bond evaporators.
• the roll-bond evaporators themselves are not coated with any paint or like finish but rather are coated with TeflonTM or like low surface friction coatings or polymers.
• the water droplets may be ionized as better described below.
• mechanical means may be provided to assist for example by the use of a mechanical resilient wiper (not shown) being translated relative to, while in contact with, the surfaces of the roll-bond evaporators, or for example the use of a mechanical shaker as better described below to vibrate each of the roll-bond evaporators in the array of roll-bond evaporators, or the use of a water spray recycling water from tray 32 and sprayed by spray- bars 46 via apertures 46a onto the surfaces 22b of the roll-bond evaporators 22 so as to provide wetted surfaces to which the water droplets will only adhere with reduced viscosity, or alternately the use of jets of air from aperture 46a for example directed downwardly onto the surfaces of the roll-bond evaporators from a linearly perforated s such as may be used to spray water onto the roll-bond evaporators so as to wet the surfaces.
• the air spray provides a downwardly moving boundary layer airflow comingling with the through- flow of air travelling in direction B in the spacing between the roll-bond evaporators.
• the spray-bars 46 are provided in parallel spaced apart array interleaved between the upper ends of evaporators 22 so that opposed facing arrays of apertures 46a formed an opposite sides of spray-bars 46 spray both sides of each evaporator 22.
• Spray-bars 46 may be supplied by a manifold 46b which itself is pressurized by pump 48 via feed-line 50.
• the roll-bond evaporators may be replaced with cooling pipes embedded in a large volume of aluminium mesh, for example sufficient volume so as to fill the inside of chassis 16 encasing water condenser 12, where the cooling pipes may be of a serpentine shape through the volume of aluminium mesh so as to attempt to equally chill the aluminium mesh.
• Fans 20 thus draw air in direction A into the pores of the mesh and the through-flow then diffuses its way through the porous mesh from the in-flow side to the out-flow side from which the airflow, as before, flows through the core of radiator 14b and then through fans 20 so as to be expelled in direction C.
• a bristled member instead of the use of aluminium mesh, a bristled member, or a plurality of bristled members having bristles of for example aluminium filaments or spikes or needles, are mounted in the spacing between the roll-bond evaporators.

• a perforated plate 44 is mounted across the inlet side of the array of roll-bond evaporators 22, for example mounted in the inlet opening to the housing formed by cowlings 18, so that incoming air in direction A has to pass through the perforations in the plate.
• the use of such a perforated plate 44 may drop the air temperature of the incoming flow in direction A while the humidity in the air remains constant.
• the use of such a perforated plate mechanically lowers the air temperature thereby better matching the temperature of the incoming airflow to that of the chilled surfaces 22b of roll-bond evaporators 22.
