Abstract |
The authors established two types of humidity control system, which utilize charcoal chips produced from construction wastes. They contain regenerating cycles using solar energy. First of them is 'pas...sive system', which is externally covered by a glass with a small air space. Another is 'hybrid system', which consists of a glass tube filled with charcoal chips and a fan for ventilation. The authors presented the numerical models of the systems and did numerical experiment. The experimental result indicates that 1) the appropriate natural ventilation was observed for humidity control using 'passive system'. 2) increase of the depth of charcoal could only increase the amount of moisture absorption of 'hybrid system', 3) Insulation for 'passive system' caused the reduction of amount of moisture absorption.show more
