Project Title

PORTABLE SOLAR WATER GENERATOR FOR REMOTE AREAS

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

Lack of water is a devastating issue on a global scale. Only3% of the earth’s water is fresh and
two-thirds of that is in frozen glaciers or unobtainable Nearly 2.7 billion people live with limited
water access at least one month out of the year as a result At current water consumption rates, it
is expected that two-thirds of the world population might face water shortages by 2025 Water
shortages are often due to lack of humidity in the air (causing little rainfall) or human activity
that disrupts the water cycle Some regions, which are experiencing high water stress, are
depleting current water sources faster than they are renewed, and the majority of this depletion is
being used for agriculture. It is estimated that 70% of the freshwater of the world is being used
for irrigation purposes Regions. In Africa, the Middle East, and Asia are affected the most
severely; however regions as close as the Midwest United States experience water shortages
annually In order to help remedy the issue, an innovative solution must be implemented to bring
a sufficient amount of water to susceptible areas. It helps improve the lives of people living in
the poorest regions of the world. In particular, this project focuses on the goal, of ensuring
environmental sustainability through the integration of sustainable principles, to reverse the loss
of environmental resources, and reduce the proportion of people without access to a sustainable
water source the motivation to help eradicate water scarcity around the world required renewable
sustainable resource and the answer was found in the atmosphere portable solar water generation
is a device used to convert humid air into water. This is done by cooling the air to a very low
temperature. In highly humid areas places as deserts and the sea, due to the lack of rainfall, we
can obtain water by condensing the water vapor in the air. This device converts atmospheric
moisture directly into drinking water form by condensing the latent heat of water vapor into
water droplets. The Peltier module is used as a thermoelectric device. The device uses the
principle of latent heat to convert water vapor molecules into water droplets. There are many
places that are situated in the temperate region; there are desert, rain forest areas, and even
flooded areas where atmospheric humidity is eminent. But resources of water are limited. In this
project, we use a Peltier device and it reduces compressor, condenser usage. This leads to
reducing the spacing and size of the equipment so we use this device. The temperature we set
inside the equipment is dew point temperature. According To previous knowledge temperature
required to condense water is known as dew point temperature

Project Objectives

The objective of the project is to create a portable device that can be used to meet the water requirements of a regular household. The device will first condense water present in the atmosphere and then purify it so that it can be used for drinking. While designing the atmospheric water generator it was identified that three requirements were necessary to ensure that the final project would effectively fulfil its intended purpose. They are Potability of Water ,Water produced by the design must conform to the World Health Organization (WHO) drinking water quality standards,Simplicity of Use - Design must be operable by persons of limited technical experience,Safety - Design must not pose a hazard to users at any point during its normal operation. We developed several goals that the design should be able to meet. They are-  Flexibility in Power Source - The design should be able to utilize a variety of power sources, including (but not limited to) solar  Maximize Efficiency - The design should maximize the water produced per unit energy.  Minimize Cost - The design should minimize the cost per unit water production for both capital cost and production costIn fact there are many products that are available in the market which use this technology. But on prior research and going through the product development page of various companies we found that the devices which use this technology are very bulky and heavy. They are not portable and since they use a compressor they have heavy electricity demand and are not eco-friendly. Also these devices produce a lot of noise and require periodic maintenance. Since we wanted to make a portable device hence we thought of using some other method to achieve our goal

The aim of the project is to create a portable device that can be used to meet the water
requirements of a regular household. The device will first condense water present in the
atmosphere and then purify it so that it can be used for drinking. The water collected from the
system will be used to rehabilitate the rural areas the dry land and affected the ecosystem due
to the water scarcity

Our project is based on the following objectives:

• Design a system to convert the air into water to use at homes to provide people with
• freshwater or can be used in farms for irrigation purposes.
•  Preserving the limited water supply in Remote areas
• Take advantage of humid weather by generating water.
•  Using the thermal electrical (Peltier) as refrigerate to condense the air.

Project Implementation Method

The most common method for creating water from air humidity is the traditional refrigeration
cycle dehumidification. This technology circulates air across cooling coils in a refrigeration
cycle to lower the dew point of the water in the air. The dew point of water is determined by the
vapor pressure and humidity, and it is usually a cooler temperature than the ambient temperature.
The air going through the unit will have significantly to achieve the dew point. The dew point of the water is dependent on the vapour pressure and humidity and tends to be a relatively low temperature compared to the ambient conditions. To reach the dew point the air running through the unit will have to be cooled a considerable amount. Vapour-compression refrigeration is the most widely used method for air-conditioning in today’s world. The vapour-compression consists of a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat to the atmosphere Basically the system has four components: a compressor, a condenser, a thermal expansion valve and an evaporator. Circulating refrigerant enters the compressor as saturated vapour and is compressed This results in high pressure which in turn is responsible for higher temperature. The compressed vapour then comes out as superheated vapour and attains a temperature and pressure at which condensation can take place with the help of cooling water or cooling air. That hot vapour is passed through a condenser where it is cooled and condensed. This is where the circulating refrigerant rejects heat from the system.The condensed liquid refrigerant known as saturated liquid is next passed through an expansion valve where there is a sudden drop in pressure. This results in the adiabatic flash evaporation of the liquid refrigerant The cold mixture is passed through the coils in the evaporator. A fan circulates the warm air in the enclosed space across the coils carrying the cold refrigerant liquid and vapour mixture. That warm air evaporates the liquid part of the cold refrigerant and at the same time, the circulating air is cooled and as a result it lowers the temperature of the enclosed space to the temperature to be achieved. The circulating refrigerant absorbs and removes heat from the evaporator which is then rejected in the condenser and transferred by the water or air used in the condenser For the completion of the refrigeration cycle, the refrigerant vapour coming out of the evaporator which is again a saturated vapour is returned back into the compressor. 

Benefits of the Project

The portable solar  water generator makes perfect, crisp drinking water from the stickiness in the air by means of a hyper-productive consolidating process. Water is made at the reason behind utilization, making this a harmless to the ecosystem and economical arrangement.

Off-lattice living is here and there an aftereffect of awkward conditions, however different times it is absolutely by decision. To get away from the expenses and governmental issues of living on open utilities, numerous families decide to utilize elective techniques for energy and water collection.Industries which require travel, like the military, can utilize an air water generator to make water when assets run short. Camping out in a desert, or a locale where there is minimal safe drinking water is a lot easier when you have a gadget like our own to persistently supply hydration.On of the greatest benefits of Atmospheric Water Generators are the expense proficiency of the gadget. While the prompt expense might offset the cost of buying versatile water from a retailer right away, the general worth improves, and a net increase is seen inside a brief time frame period.

One more advantage of this technique for water recovery is no extra working costs, and in light of the fact that the air water generator is independent, there are no electric bills.Finally, a significant motivation to carry out an environmental water generator is for crisis and clinical purposes. Having one of these units convenient during recuperation endeavors can assist with obtaining drinkable water for families, store supplies, medication and blood, close by different necessities.Whether you are residing in a far off region, or your occupation is assuming you to a position where day to day environments are not exactly ideal, we take care of you with regards to clean drinking water! majority of people being
unable to consume clean drinking water in most of the developing or under-developed
countries globally, we ensured that our project can be constructed in such a way that it
requires very less financial support to produce. Once produced successfully, the common
majority can drink the water being generated from the humidity present in the surrounding
atmosphere

Technical Details of Final Deliverable

Basically, our venture has been an extremely enormous test particularly thinking about that there
has been past done currently previously yet with a great deal of spending plan in the bank. Nonetheless, we
provoked ourselves to do likewise however with minimal measure of financial plan being spent on our
framework since we are going for the gold who don't have monetary means to bear such
large frameworks which can produce water from climate. However, taking everything into account, we as a
bunch did what was unattainable in the time span of these three months.
Furthermore, in particular, we had the option to shield our target of this model which
incorporated the appropriate creation of drinkable water where there is no admittance to clean drinking
water and where individuals are dwelling in outrageous moist circumstances. In this way, the framework can
effectively utilize the ecological circumstances and boundaries to be useful and valuable.
