The renewed multi-section comb rotor applied the characteristics of traditional rotor. It divied the rotor into eight sectore, of which two are regenwrating sections, one is cooling, and the rest five are drying ones. While the rotating insulator absorbed enough water regenerating air then made wager molecules in the regenerating section get out of attachment thus expelled out of the chamber. The obvious characteristic of the ren-ewed multi0section comb rotor is move only one section each time, with smooth curve of dehumidifying performance and stability as well.
