| 内容記述 | The thermal diffusivity of insulation panels consisting of wood shavings is smaller than that of the glass-wool panels that are commonly used in buildings as insulation material. In the present study, the heat-storage capacity of wood-shaving insulation panels was compared with that of glass-wool panels, focusing on daily changes in room temperature in winter. The moisture gradient of wood-shaving insulation panels was also examined with respect to the avoidance of dew condensation. The panels were installed in two different rooms, with the same structure and thermal resistance, of a small one-story house (18m^2) built in Morioka, Japan. The rooms were heated for 12 hours a day (0-12pm, 20℃) by an air conditioner, and the surface and air temperatures of the two rooms were compared. Minimum room temperatures in the early morning were found to be 2℃ higher in the room with wood shaving insulation panels. This was due to the fact that room surface temperatures were 0.6-1.6℃ higher, since the thermal diffusivity of the wood-shaving insulation panels is half that of the glass wool panels. However, the amount of heating energy required was 4% greater in the room insulated with the wood-shaving panels due to a 30% greater heat mass. During one-week of continuous room heating in the dead of winter, a large moisture and temperature gradient developed throughout the thickness of the wood-shaving insulation panel. When the temperature gradient reached 20℃, the moisture content was 24% at the lowest-temperature surface and 5% at the highest-temperature surface. However, dew condensation was not observed. Measurement of heat-flow in the presence of this moisture gradient revealed that the thermal conductivity of the wood-shaving insulation panel did not change. Moreover, the moisture gradient disappeared with in a couple of days following the disappearance of the temperature gradient, suggesting that moisture permeability is great inside the wood-shaving panel. |
