Abstract
A system and method utilize one or more fans each having fan blades. The fan blades have a desiccant material on an outer surface. The desiccant material is operable to adsorb airborne moisture in an ambient airflow and desorb moisture in a heated airflow. The fan blades are operable to drive one or both of the ambient airflow and heated airflow via rotation of the fan.
Claims20
A system comprising:
- one or more fans each comprising fan blades, the fan blades comprising a desiccant material on an outer surface of the fan blades;
- an ambient airflow that flows across the fan blades to adsorb airborne moisture in from the ambient airflow to the desiccant material;
- and
- a heated airflow that flows across the fan blades to desorb moisture from the desiccant material via the heated airflow, the fan blades being operated to drive one or both of the ambient airflow and heated airflow via rotation of the fan.
