In this study, a dehumidification performance simulation model is developed for desiccant wheel based on the Gas Side Resistance (GSR) model. A sine wave single-channel with silica-gel is chosen as a simulation model, and a finite difference method is introduced to solve one-dimensional heat and mass transfer equations. The simulation results according to the cycle of the desiccant wheel are compared with the experimental results, and 2% mean error is shown. A simulation of the desiccant wheel is performed under the conditions of a regeneration time of 256s and a dehumidification time of 256s. In the regeneration section, wet air flows into the desiccant wheel at an absolute humidity of 0.01930 ㎏·㎏<SUP>-1</SUP>, and gradually decreases after showing a maximum value of 0.03541 ㎏·㎏<SUP>-1</SUP>. In the dehumidification process, wet air flows into the desiccant wheel at an absolute humidity of 0.01930 ㎏·㎏<SUP>-1</SUP> and increases gradually after showing a minimum value of 0.00701 ㎏·㎏<SUP>-1</SUP>. In addition, the simulation of the present study closely replicates the saturation phenomenon and the equilibrium state between the desiccant wheel and wet air.

The purpose of this research is to examine, within residences at Chonnam region in the late Chosun dynasty, whether there exists a regional peculiarity, and if it does, to clarify the differences and characteristics between subdivided regions. On the basis of this, the goal is analyze the characteristics of the composition of space developed in the residential arrangements of middle & upper class in Chonnam region. For the methodology of analysis, first, to observe the regional peculiarity divided by administrative division via measured data, I analyzed geomantic aspect of the dwelling house, Chae (buildings) and Madang (court), the arrangements of the Chae, the dwelling house and those examined through planning. Second, analyzed the distribution based on each regions. Third, because of these analysis deals with the regional peculiarity described within the arrangement planning, once again I will make a close examination on the effects and characteristics to the arrangements and types.
