Fresh water scarcity represents a major world challenges, in addition, the water consumption is increasing with population growth and evaporation due to global climate changes. Furthermore, seawater desalination is considerably cost, requires additional energy to extract it, and negatively affecting water quality. The modern technologies adopted deferent methods to extracting the fresh water from the atmosphere. This work aims to contribute in solving this scarcely fresh water problem through, condensing the humidity in the air and transform it to fresh water. The proposed system is integrated into three parts; mechanical, electrical, and water treatment with filtration unit. The mechanical system consists of a refrigerant cycle with a compressor capacity of 1.5 horse power. The electrical system is responsible of controlling the mechanical system through the Arduino Uno circuit and relay. The filtration system is used to remove sediments and contaminants from the harvest water. The water treatment unit is used to supply the filtered water with the required additives of minerals to transform the distilled water to fresh drinkable water. The system design takes the energy efficiency into account. The system behavior is analyzed, taking into account real climatic conditions of Egypt. Preliminary calculations show that the water extracted from air by condensation is ranged from (8.25 to 12) litters during six operational hours per day. The produced quantity of fresh water can be support the needs from three to four persons per day. The total saving of produced water from the proposed system compared with the price of water in the market is 80,416.8 L.E per year.
