Abstract

The present invention according to at least one aspect describes the production of water by condensation of air humidity using a lower than ambient temperature cooling system to collect water into a suitable reservoir. A machine cools stainless steel tubing with use of the glycol cooling media at 5° C. flowing inside the tube. Outside of the stainless steel tube, fans create differences in temperatures so that the humidity can condensate and turn into water, which then flows into a reservoir at the bottom of building. Minerals can be added or naturally produced by having the water flow in a lake or other reservoir and can again re filter or use reverse osmosis for drinking purpose. A system of compressors can be used for cooling the glycol inside the tube. The electricity used by these compressors is provided by either grid electricity or by renewable resources.

Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application claims the benefit of U.S. Provisional Application 61/975,242, filed Apr. 4, 2014, entitled Water production system by condensation, which is incorporated herein by reference.
  • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present application relates to the production of water from the air.
  • 2. Statement of the Problem
  • In many places in the world, there is a shortage of potable water due to human consumption or to drought. Due to increase in population, during the next fifty years there will likely be WAR over WATER. Currently in the state of California, US water reservoirs are drying up due to successive droughts and to high human consumption. This situation has caused a lot of problems for the farmer in the form of a lack of water for irrigation and even for water for drinking. Such a discovery of a new source of water reserves will help resolve a lot of problem related to the shortage of water.
  • SUMMARY OF THE INVENTION
  • The present invention according to at least one aspect describes the production of water by condensation of air humidity using a lower than ambient temperature cooling system to collect water into a suitable reservoir.
  • A machine according to the present invention cools stainless steel tubing with use of the glycol cooling media at 5° C. flowing inside the tube. Outside of the stainless steel tube, fans create differences in temperatures so that the humidity can condensate and turn into water, which then flows into a reservoir at the bottom of building. Minerals can be added or naturally produced by having the water flow in a lake or other reservoir and can again re filter or use reverse osmosis for drinking purpose. Each tube is preferably about 100 meters long and has the ability to produce within 24 hours approximately 120,000 kilos of water. A system of compressors can be used for cooling the glycol inside the tube. The electricity used by these compressors is provided by either grid electricity or by renewable resources.

  • DETAILED DESCRIPTION OF THE INVENTION
  • Earlier designed systems used steam to generate purified water and did not provide a good yield. That is, the steam purified water output will be equal to the water input without any gain.
  • Therefore the inventor has designed a new system that can produce water utilizing condensation. The invented machine cools 316 stainless steel tubing with use of the glycol cooling media at 5° C. flowing inside the tube. Outside of the stainless steel tube, blowing fans create differences in temperatures so that the humidity can condensate and turn into water, which then flows into a reservoir at the bottom of building.
  • The same concept for water condensation can be used with refrigerator, i.e., a refrigeration cycle, using different temperatures to obtain the water.
  • The design using 316 stainless tube is used for pharmaceutical production, therefore production of drinkable (“potable”) water is possible. As for irrigation, ongoing studies are analyzing the lack of minerals in the produced water. Regardless, minerals can be added or naturally produced by having the water flow in a lake or other reservoir and can again re filter or use reverse osmosis for drinking purpose.
  • Production of water: Each tube is about 100 meters long and has the ability to produce within 24 hours approximately 120,000 kilos of water. If we build 100 tubes of 100 meters, we could produce 12,000,000 kilos of water
  • Design Structure: A building 200 meters in length, 100 meters wide and 15 meters in height, housing 100 tubes of 316 pharmaceutical grade stainless steel of 200 meters in length. Underneath all of these 100 tubing, a water catcher flowing down to the end of the tube is used to get down to the Reservoir below to retain water made/captured during the process. Excessive production of water can be sold to Water Company.
  • A system of compressors can be used for cooling the glycol inside the tube. The electricity used by these compressors is provided by either grid electricity or Rain, Sun, Wind and Water electricity power station (under U.S. patent application 61/847,646) that can be placed on the top of this “water production by condensation” system housing.
  • 1. Requirement for Water Produced:
  • Use the Water Maker to make water from air by Air-cooling Refrigerator System for daily life use:
  • ------ Washing/bathing
  • (------ If add special filter to the outlet, the water will be drinkable)
  • 2. Pre-Conditions of Design:
  • Each different areas has its own climate, a key influent element to the design of Water Maker. Here, defining the pre-conditions of the design:
  • A> Environmental relative humidity: 40%, Temperature: 15-35° C. (inlet T)
  • B> Mechanical dew point temperature set at 0° C.
  • C> Air dry bulb temperature is unified set at 0° C. (outlet T)
