SD-014V: Desiccant Dehumidifier

I looked at the manual for this unit, see below...

I have no idea if this represents typical effficiency, but a vapor compression unit that draws 650 W would be able to remove about three times the amount of humidity.

So for this scheme to be competitive, some kind of "free" power like either solar thermal or solar PV might be required.
