Abstract

Regional economic, social, and ecological security are all entwined and influenced by the availability of water. Since the available water resources are depleting at a very faster rate and people are restricted to access the clean water, it is urgent to discover new & alternative sources of fresh water to meet everyone's requirements. An inexpensive and effective solution to the rising problem of the water shortage can be atmospheric air to water generation (AWG) technology. This study involves the development and experimental investigation of a novel AWG system based on adsorption under ambient conditions. Both end open evacuated tube collector solar air heater (ETC-SAH) with 5.07 m2 solar collector area and an air-to-air condenser is used. The system’s performance is evaluated based on several key parameters, including adsorption & regeneration rate, energy & exergy efficiency, and economic analysis. The fresh water yield reported from the system is 3.08 L/day at 0.12 $/L cost. The energy & exergy efficiency reported by the system is 9.65% & 3.69%, respectively. Additionally, the water produced is subjected to testing at a regionally certified laboratory to confirm its safety for consumption.
