<p><P>PROBLEM TO BE SOLVED: To provide a dehumidification filter which has high dehumidifying function and the capability to easily and certainly regenerate itself at a lower temperature than conventionally set and ideally at normal temperatures and is very useful in terms of energy saving and device miniaturization, when this filter is applied to a desiccant rotor. <P>SOLUTION: This dehumidification filter has the characteristics: a dehumidifying material formed of siliceous shale with numerous pores having an average pore diameter of 3-18 nm and a specific surface area of not less than 80 m<SP>2</SP>/g, is made to deposit on or to be included in a base material to be used for a desiccant rotor of a desiccant air-conditioner. The dehumidifying material is left at rest for 24 hours under environments at a temperature of 40°C and a relative humidity of 30%, and then is left at rest for two hours under environments at a temperature of 30°C and a relative humidity of 75%. In this case, the dehumidifying material shows a mass increase of not less than 60 mg/g. In addition, the dehumidifying material shows a mass decrease of not less than 60 mg/g when it is left at rest for two hours under environments at a temperature of 40°C and at a relative humidity of 30%. Besides, a deliquescent material adheres to, at least, the interior of the pore of the siliceous shale showing the difference between the mass increase and the mass decrease of not more than 20 mg/g. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
