LIQUID DESICCANT VAPOR SEPARATION SYSTEM
An atmospheric moisture harvesting system, in which water vapor is separated from the air using a liquid desiccant subsystem. The moisture charged liquid desiccant enters a desorber and condensation system, where the moisture is extracted. Cooling and condensation are performed on the extracted water vapor only, thereby saving the energy for cooling air containing the water vapor, as is done in direct cooling systems. The system thus operates as a single stage vapor separation system since the vapor concentration remains in the liquid desiccant which is circulated to the separation and condensation subsystems without air laden with the moisture. Low grade or solar heat can be used as the energy source for the vapor desorption. A heat exchanger utilizes unwanted heat from regenerated desiccant to heat up charged desiccant entering the regenerating stage. The system has substantial energy savings over prior art systems using direct cooling of air.
