| Abstract | ||
| The desalination system by humidification and dehumidification has shown great success in desalinating highly saline sea water , This system is also characterized by the high quality of the water leaving it, where the percentage of pollutants and salts in the water was almost non-existent. In the implemented HDH system, the air enters through a blower into the duct and passes over the condenser of the cooling system, so the air temperature increases and the condenser temperature decreases, which enhances the efficiency of the dehumidifying unit. The air temperature is more, then the hot air passes over the humidification unit, where the salt water is sprayed at high temperatures, which increases the percentage of air humidity, as the air carries a high percentage of water vapor, and a portion of the highly saline water remains, which is discharged through the drain, in The final stage, the air loaded with water vapor passes over the dehumidifier, and a large part of the water vapor condenses and is collected in the desalinated water tank he system reaches its highest water production of 17.64 L/hr at an air flow rate of 504 kg/hr with a fully open setting. With a fully open setting and 504 kg/hr air flow, the system produces around 141.1 L of fresh water per day, significantly more than the 55.6 L produced with a 252 kg/hr air flow. This configuration yielded a local water production of 17.64 liters per hour, with a production cost of 0.029 dollars per liter. | ||
