Abstract:
Water scarcity is one of the most serious and critical issues of today's world. Water is considered one of the most important resources in the world. Despite the fact that water covers more than two third (about 70%) of the Earth's surface, but fresh water which can be used for drinking and carrying out everyday chores still scarce (only about 2.5%). The world faces major challenges due to fresh water scarcity. In addition, the demand of clean water is increasing, and the water is getting reduced by evaporation due to global warming, and water quality is getting affected due to water sources pollution.
Furthermore, seawater desalination is not within everyone's reach as it requires additional energy to extract it, and negatively affecting water quality. The technical and scientific solutions that is currently available to this serious problem is partial and costly. Therefore, the world is facing a critical problem in what is considered the source of life for all human beings. This project aims to contribute in solving the clean drinking water problem through the air condition units by condensing the humidity in air, and transform it to fresh water. The proposed system unit is divided into three parts: mechanical, electrical, and the water treatment and filtration system to guarantee the expected outcome from the collected water.
The mechanical system consists of a refrigerant cycle with a compressor capacity of 1.5 horse power, while the electrical system is responsible of controlling the mechanical system through the Arduino Uno circuit and relay. Technically, the air conditioner condensate distilled water. Therefore, the collected water passes through the water treatment process and filtration system to remove sediments and contaminants, and to gain the required additives of minerals to make this type of water drinkable. After assembling the device, the tests have been conducted to measure the amount of water collected that ranged between 1.6 to 2 litters during 6 operational hours per day. Therefore, the amount of condensed water varies according to the environmental weather conditions
