Water conservation

Abstract

What is disclosed is the idea and method for utilizing wasted water that is, a by product of the chillers and air conditioners, especially in humid regions of the planet to provide water for drinking and other potable water applications. This water is generated at the location of the air inlet chiller units of central air conditioning units that are placed on the roofs of high rises and on central raised locations. Today this condensed water is a problem and is discarded down the drain. The placement and location of central AC units, on top of buildings and industrial complexes allow water to be collected and supplied by gravity, to the usage area. By providing a collection tank with filtration and preferably UV irradiation capability, the collected water can be made potable with no further treatment. Such a scheme will reduce the usage of piped water in the cities.

1 . A method for collecting and using the water that condenses from the humid input air stream as it is cooled below dewpoint in the expander and cold unit of the central air conditioner. 
   
   
       2 . The method for collecting and using the water that condenses from the humid input air stream in  claim 1 , where in a precipitator unit attached to the cold unit enhances the precipitation of moisture. 
   
   
       3 . The method for collecting and using the water that condenses from the humid input air stream in  claim 1 , where in, the precipitated water is collected in a Precipitated water collection chamber. 
   
   
       4 . A method for collecting and using water that condenses from humid input air stream in an air conditioning unit where the collected water is purified for making it potable. 
   
   
       5 . The method for collecting and using the water that condenses from the humid input air stream in the air conditioning unit in  claim 4  where in, the water is purified by filtering. 
   
   
       6 . The method for collecting and using the water that condenses from the humid input air stream in the air conditioning unit in  claim 4  where in, the water is irradiated by UV radiation to make it drinkable. 
   
   
       7 . A method of precipitating the excess water from an input air stream during cooling in a precipitation chamber attached to a cooling chamber, where by the output air is less humid, which when mixed with re-circulated air provide optimum humidity conditions for comfort. 
   
   
       8 . The method of precipitating the excess water from an input air stream during cooling in a precipitation chamber attached to a cooling chamber, where by the output air is less humid and when mixed with re-circulated air provide optimum humidity conditions for comfort in  claim 7 , where in, the ratio of mixing of the output air and the re-circulated air can be adjusted to provide optimum humidity and temperature in the room. 
   
   
       9 . The method of precipitating the excess water from an input air stream during cooling in a precipitation chamber attached to a cooling chamber, where by the output air is less humid and when mixed with re-circulated air provide optimum humidity conditions for comfort in  claim 7 , where in, the reduced humidity of the air reduces mold growth. 
   
   
       10 . The method of precipitating the excess water from an input air stream during cooling in a precipitation chamber attached to a cooling chamber, where by the output air is less humid and when mixed with re-circulated air provide optimum humidity conditions for comfort in  claim 7 , where in, the reduced humidity reduces damage to furniture and fittings.
