Experimental investigation of solar desalination unit performance using air-pressurized humidifier with economic analysis

Abstract Water is essential for life on Earth. Desalination may reduce water shortages by turning salty water into drinkable water. We study a solar desalination process that combines a humidifier and a dehumidifier. The present work measures solar HDH desalination distinctively using an air-pressurized humidifier. This humidification technique employs an air-pressurized humidifier to increase water droplet dispersion and decrease droplet size. The experiment examines compressed air flow, air pressure, nozzle diameter, and humidification pattern breadth. Water output increases due to the broader spraying pattern and smaller air-pressurized nozzle. The suggested system produces 27.8 kg of distilled water every day for 0.0066 $ per liter.
