A solar water desalination system based on the humidification and dehumidification (HDH) process was designed, built, and tested by varying the air mass flow rate. The study explored three different air flow rates: 0.00276 kg/s, 0.02022 kg/s, and 0.02682 kg/s. The system included a combined solar air/water heater with double glass, a humidifier (evaporator), a dehumidifier (condenser), a circulation pump, a fan, and a storage tank. Both the air and brackish or low-salinity water were heated simultaneously in the combined solar air/water heater. The results indicated that increasing the air mass flow rate significantly improved freshwater production, suggesting that higher air flow rates yield greater water output. The system reached its peak productivity of 570 mL/day on October 6 at an air mass flow rate of 0.02682 kg/s.
