This study investigates a hybrid-solar desalination system consisting of a humidification-dehumidification unit and a solar distiller unit. The system was tested in real thermal conditions and showed good agreement between predicted and measured water production and performance parameters. The system achieved high productivity and efficiency, making it a promising solution for desalination using solar energy.
Experimental investigation of a hybrid-solar desalination system consisting of a humidification-dehumidification unit and a solar distiller unit. At El Mahalah city- Egypt in climatic conditions, experimental work was performed under real thermal conditions in September 2021. A new design of helical humidifier and multi-section solar distiller has been tested. There is good agreement between the predicted and measured changes in water production and performance parameters. According to testing and operating parameters, the system's highest productivity was 6.7 kg/m(2) per day at a production cost of 10.4 $/m(3). System performance was tested and represented by system efficiency, humidifier efficiency, and gain output ratio (GOR). The system efficiency, humidifier efficiency, maximum gain output ratio, and exergy efficiency reached 95%, 98%, 1.65, and 7.2%, respectively. The proposed hybrid desalination system gives an adequate operational compatibility between the HDH method and solar energy.
