Optimization and Performance Analysis of Desiccant Wheel-Assisted Atmospheric Water Harvesting Processes

To solve the fresh water scarce problem in dry regions, a desiccant wheel-assisted atmospheric water harvesting system is designed. Using water production rate as the index, studies are conducted to find the optimized air handling process under typical ambient conditions, considering influencing fac...
