The objective of this study is to develop a desiccant system using Wakkanai Siliceous Shale (WSS). This article is the 7th report of the series. In the previously articles, we reported a developed desiccant unit to achieve the target amount of dehumidification. This unit consists of two desiccant rotors and two heat exchangers for precooling and two heat exchangers for regeneration. In this paper, the authors have made a mathematical simulator of this desiccant unit to estimate the supply air conditions. The input conditions for regeneration and precooling have been evaluated by using this program. Firstly, the calculation precision of the program is confirmed by comparison with experimental results. Secondly, to minimize the input energy for the desiccant unit, input temperature for precooling and regeneration are evaluated. The conditions are obtained by controlling of precooling temperature depression without occurrence of dew condensing on the heat exchangers. Finally, performance prediction was carried out to obtain the energy saving efficiency in various areas in Japan. As a result, the unit reduced the energy for dehumidification by 30 % to 18 % in comparison to dew condensing process.
