This article is the 3^rd report of the series. The objective of this study is to evaluate the dehumidification amount of newly developed desiccant rotors by using paper containing Wakkanai siliceous shale (WSS) which is a natural mesoporous material in Hokkaido. The dehumidification amounts were evaluated at the following air conditions (OA: 30 ºC, 75 %RH, RA: 40 ºC, 27.3 %RH). The WSS rotor and a B type silica gel rotor (400 mm of the rotor diameter and 200 cpsi of the rotor cell numbers) showed same values of 3.1 and 3.2 g/kg_DA at 1 rpm of rotation speed, even though the maximum water adsorption amount of the B-type silica gel is three times higher than that of the WSS. To enhance the dehumidification ability of the WSS rotor, an impregnation of NaCl and MgCl₂ into the WSS paper was carried out, and it gave more than 3.8 g/kg_DA. In addition, for the development of the compact desiccant system, dependency of the rotor rotation speed, the size of the rotor diameter, and a rotor cells number were examined. Finally, 4.7 g/kg_DA was obtained at 500 mm diameter and 270 cpsi of the rotor cell numbers.
