to dehumidify a living space by batch processing, with regeneration with waste heat which exhausts outside the living space, I seek a material which is a strong hydroscope, but is not deliquescent.
I'm in and out of the house a few times of the day anyway, I can live with an additional chore of exchanging buckets of stuff
I'm fiddling with table salt, with brake fluid and with brown sugar.
Anything better at pulling quantities of water vapor out of the air? Toxicity is no problem, as no children will be present. For the moment, I want to try avoiding actual deliquescents... regenerating them is klugey.
The IDEAL material would have a low heat of hydration... the less ambient latent heat getting converted into sensible heat, the better. Although, sensible heat is easy to dispose of in conditions of low humidity.
