Project Summary

Lack of fresh drinking water and energy is a combination that fails to fulfill the demand of drinking water of the people of Pakistan who stays at the coastal and mountain side such as Karachi and Gawadar(Baluchistan)). This leads to the idea of fulfilling their demand of water in a cost effective way. Also the lack of electricity supply is the main concern. Water purification system or compressor based AWG is expensive and unaffordable for the poor people. Moreover, many rural areas of Pakistan do not have electricity supply. Keeping these in consideration, a system needed to be developed that will be cost effective as well as easy to operate. Solar being an excellent source of renewable energy, it has been used in this project making it a total off grid system using batteries as backup. By virtue of that the coastal and mountain side people will be relieved from the pressure of fresh drinking water without paying for electricity. An army when they are in desert area or hilly areas, on border where there is no water for drinking purpose so they can use this kit  easily . In Pakistan, solar powered Peltier cooling system has not been introduced yet. This project is the first attempt incorporating solar power into cooling system. Successful implementation of this project can meet the demand of water of the sea side people and also improve the economy of the country. Moreover, it will consume less power, it is cost effective and can run the AWG system efficiently.

Lack of water is devesting issue in all over the world. As the human body contains 70% of the water and the dehydration can result in death 75% of the earth is covered by the water. Without water there is no life. Plants need water to survive and plants are necessary part of the society and for the human beings as they return us the oxygen without water they cannot survive they need proper care and water to survive. The water in the atmospheric air can be extracted by implementing a device like atmospheric extracting water generator using solar panel or battery for example, when we say 60% humidity at 20centigrade one cubic meter of air will contain about 10gms of water. The efficiency of the device depends on the atmospheric condition as well as changing of weather 7 days in a week. The final design of this project will be capable of extracting humidity from the air and convert it into usable for drinking and as well as for plants and irrigation.

Project Objectives

Our primary aims are:

1. Harvesting  Water from thin air for places where there is lack of water for drinking and for irrigation purpose
2. Portable kit which can be used anywhere for drinking purpose and plants.Using Peltier that is of less cost.

Indeed there are numerous items that are accessible in the market which utilize this innovation. Yet, on earlier research and experiencing the item improvement page of different organizations we found that the gadgets which utilize this innovation are extremely cumbersome and substantial. They are not compact and since they utilize a compressor they have overwhelming power request and are not eco-accommodating. Additionally these gadgets create a considerable measure of commotion and require occasional support. Since we needed to make a convenient gadget consequently we considered utilizing some other strategy to accomplish our objective. In their outline report “Water generator water from air using liquid desiccant method" Niewenhuis [1] and others have attempted to use fluid desiccant strategy for dehumidification. After they made a model and place it into testing they found that water yield from the gadget was extremely less. Consequently we chose not to utilize this strategy for dehumidification for our model. After experiencing all the accessible choices we at last inferred that we would utilize a Peltier gadget to make the Atmospheric Water Generator. We propelled the review by making a model first and afterward subjecting the model to comsol multi physics software. At that point we computed for various ecological and relative humidity conditions, the dew point temperatures and after that counted it with the outcomes acquired from examination. Subsequent to getting the outcomes we gathered the metrological information for various costal and mountain areas of Bangladesh and investigated whether our proposed model would work or not. Additionally for purification of dense water we chose to utilize a monetarily accessible filtration unit. This guaranteed the water which is acquired from the gadget is consumable and free from any microbes and germs.

Project Implementation Method

The proposed solar powered AWG consists of one solar panels, one rechargeable batteries, one pulse width modulation (PWM) charge controller, two thermoelectric cooler, two dc fan and two heat sink. There will also be a backup system which will be controlled by the Double Pole Double Throw (DPDT) switch.

Benefits of the Project

Lack of fresh drinking water and energy is a combination that fails to fulfill the demand of drinking water of the people of Pakistan who stays at the coastal and mountain side. This leads to the idea of fulfilling their demand of water in a cost effective way. Water in one of the precious resource for living on earth. Everyone needs water for their daily requirements. Drinking water is blessing for everyone. Project main object are:

• Provide water to plants for their Growth.
• Provide water for drinking.

Solar is being an excellent source of renewable energy, it has been used in this project making it a total off grid system using batteries as backup. By virtue of that the coastal and mountain side people will be relieved from the pressure of fresh drinking water without paying for electricity. An army when they are in desert area or hilly areas, on border where there is no water for drinking purpose so they can use this kit  easily .

Technical Details of Final Deliverable

As compressor refrigeration system is more costly and create sound, we utilized Peltier cooling. Powering the device with PV boards 5 | P a g e and batteries is the most sensible choice to run the AWG device. The majority of the sun based cooling system incorporate AC compressor and inverter which alters the DC current taken from the PV boards to AC. However, this procedure is wasteful and energy is squandered while DC current is changed over into AC by the inverter. Though, Peltier cooling is more productive as far as power effectiveness and power utilization. Additionally, its voltage is effectively controllable.

How does a Peltier element work?

Thermoelectric coolers operate according to the Peltier effect. The effect creates a temperature difference by transferring heat between two electrical junctions.When the current flows through the junctions of the two conductors, heat is removed at one junction and cooling occurs.

Peltier element

An electronic device consisting of metal strips between whichalternate strips of n-type and p-typesemiconductors  are  connected. Passage of a current causes heat to be absorbed from one set of metallic strips andemitted from the other by the Peltier effect.

Solar Photovoltaic Panels In the period of industrialization, practicing environmental safety with sun based is the best arrangement. Sunlight based boards have been utilized worldwide and it is easy to store and generally safe to use in business purposes. Sunlight based photovoltaic boards are being utilized worldwide for creating power. The innovation of retaining sun's beam to energy has included numerous parts of utilizing the sun based as sustainable power source
