Zero Energy Air to Water Extractor
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryAtmospheric water generation is one of the promising methods for getting pure water. Because of pure water scarcity in many regions worldwide, finding alternative methods for pure water generation becomes beneficial enough to motivate many researchers to work on related topics. Solutions for water scarcity are based on various water-saving strategies, reclaiming of used water, and water production. Seawater desalination by reverse osmosis is the most common and efficient water-production method. However, it requires a large saline or brackish water source and is therefore not applicable in regions with no access to brackish or sea water.
Atmospheric water generators (AWGs) apply vapor compression refrigeration to extract water vapor from the surrounding air. They produce drinking quality water, and they require moist air and electricity. This project consists of a thermoelectric Peltier (TEC) couple, which is used to create the environment of water condensing temperature or dew point, indeed conventional compressor and evaporator system could also be used to condense water by simply exchanging the latent heat of coolant inside the evaporator. The condensed water will be collected to use for drinking purpose and various other uses.
Project ObjectivesThe main objective of this project is to create a product that can produce safe and clean drinking water while only consuming air and energy. Due to natural water shortage in lots of regions worldwide such as in our country Pakistan, locating alternative methods for natural water technology becomes useful enough to inspire many researchers to motivate on associated topics. therefore, using renewable energy resources which are in abundance in a country like Pakistan itself, we have come up with a project which can make use of wind and solar energy at the fullest.
Project Implementation MethodThe location we have considered is a place which is more of a desert becuase that is where this project will be fully functional. we connected a windmill to the frame. the frame is made of stainless steel. We have checked the output of solar panel and it is 19.72V and 2.02A. we have checked the output of sensors and peltier devices. we will assemble the project in such a way that the frame has a chamber inside which peltier devices will be connected. the chamber will trap air from windmill and push it down. the peltier will be able to convert water from atmospheric air because air has a level of moisture in it. With the right amount of temperature, water vapors can convert into water droplets. at the end of the frame, there is a tank which will be able to collect the water that is generated from this porcess.
Benefits of the ProjectThis project will be able to convert water from atmospheric air because air has a level of moisture in it. With the right amount of temperature, which is called dew point temperature, water vapors can convert into water droplets. At the end of the day, the tank will be able to collect 10-15L of water with the help of this generator.
- Production of water for potable or sanitary demand
- Production of water in arid region for technical applications such as cleaning and irrigation.
- It can be used in deserts where there Is water scarcity.
We have used battery, wind and solar energy because we can't always rely on one source, if either of them fails we will always have backup to fuel our project. the windmill serves two purposes, it will generate electricity and trap air in the frame. we have a frame made of stainless steel in which air will be trapped. the trapped air will pass through dust filters to ensure cleanliness. Inside the frame, we have peltier devices fitted. peltier effect creates a temperature difference by transferring heat between two electrical junctions. A voltage is applied across joined conductors to create an electric current. When the current flows through the junctions of the two conductors, heat is removed at one junction and cooling occurs. The Peltier thermoelectric device has two sides (a p-type and an n-type semiconductor), and when DC current flows through the device, it brings heat from one side to other, so that one side gets cooler while the opposite one gets hotter. when the temeprature of air is below dew point, the air willl start to condense and water will be collected in the tank which is at the end of the frame. at the end of this process, we will get 10-15L of water a day.
