Abstract
The objective of this study is to develop a desiccant system using Wakkanai Siliceous Shale (WSS). This article is the 5th report of the series. In the first part of this paper, various parameters of the WSS rotor were estimated by the numerical calculation to find the higher dehumidification amount. An optimal rotor configuration was selected as 500 mmφ of the rotor diameter, 60 mm of the rotor thickness and 270 cpsi of the rotor cell number. In the second part, as a calculation model for the desiccant ventilation, an appropriate system, which consists of two rotors with two heat exchangers for pre-cooling and two heat exchangers for regeneration, was applied. To get over the target value of the dehumidification amount (7.6 g/kgDA), the numerical simulation was carried out based on the desiccant ventilation model. As a result, the maximum dehumidification amount of 8.6 g/kgDA was obtained at 0.5 rpm of each rotor rotating speed.
