Abstract

Abstract

An experimental investigation was conducted to explore the factors influencing the water harvesting efficiency of an air-water harvesting device. The results indicate that fan speed, ambient air temperature, and relative humidity significantly affect the performance. During the experiments, it was observed that condensate on the surface of the fins failed to shed promptly. Instead, it adhered between fins and formed water bridges, which negatively affected the water harvesting efficiency. To address this, the condenser fins were optimized. Using COMSOL for modeling and simulation, the fin structure of the semiconductor refrigeration air-water harvesting device was optimized, and hydrophobic materials were coated on the fin surface to facilitate rapid condensate shedding, thereby increasing the device's water harvesting efficiency.
