Abstract
Experimental research about highly-efficient-izing of a desiccant rotor used for a desiccant air-conditioner (Dehumidification) which attracts attention as exhaust heat use apparatus of cogeneration. A moisture absorption characteristic of various desiccant materials were compared with the dehumidification performance for the desiccant rotor using the desiccant material, and the characteristic required for highly-efficient-izing is explored.
