Abstract:
1. A portable device for collecting freshwater from hot moisture-laden gas and supplying potable water to a limited number of passengers on a transport vessel, said device comprising: inlet means for directing the hot moisture-laden gas inside a chamber; a filter for essentially eliminating solid particulates contained in the hot moisture-laden gas before the hot moisture-laden gas enters into said chamber; outlet passage means for discharging dry gas from said chamber after moisture is removed from the hot moisture-laden gas; an air fan for drawing the hot moisture-laden gas from said inlet means through said chamber an into said outlet passage means; a thermoelectric cooler for cooling a circulating stream of cold freshwater; a plurality of spiral condensation coils for condensing moisture from the hot moisture-laden gas when the hot moisture-laden gas comes into contact with said plurality of spiral condensation coils to produce drippings of condensate that fall by gravity from the surfaces of said plurality of spiral condensation coils; a water pump for circulating the stream of cold freshwater through said plurality of spiral condensation coils; condensate collection means for collecting a freshwater product from the drippings of condensate that fall from the surfaces of said plurality of spiral condensation coils; treatment means for disinfecting and filtering the freshwater product to produce potable water; potable water holding means for storing said potable water; dispensing means for drawing said potable water from said potable water holding means; and power supply means for supplying electric power to said device.
