Regeneration of Liquid Desiccants in Evacuated Tube Solar Collectors [PDF]

, 2014
Liquid desiccants can be regenerated by heating the solution to evaporate water from the solution. While conventional methods rely on the vapor pressure difference between water in the solution and that in moist air, it has been proposed to directly boil
