19981) Transport mechanism and distribution of VOC inside constructing wooden materials and its emission1.1 Emission of VOC from constructing wood material and transport mechanismComponents and concentration distribution of VOC inside wooden constructing material were measured. Emission rate of VOC from the material surface was measured under various surface temperatures of material. It was found that emission rates increases with temperature and changes with components and constructing materials.2) Generation of particulate materials in an indoor space2.1 Effects of the walking motion on dust re-suspension from floor surfaceThe amount of dust re-suspension from floor by walking was measured for various speed of walking. It was clarified that the amount of re-suspended particles increased with the walking speed and changed with floor and shoes materials.3) Numerical analysis of flow patterns in an indoor space3.1 Fundamental study on the layered ventilation of the semi-closed space wit … More h heat and dust generationFlow in an indoor space, where a heat and dust source exists, was visualized and the numerical analysis was conducted to discuss the condition for the layered concentration distribution of dust. It was found that a circulation flow below mid height of the space is effective when the buoyancy flow from heat source is predominant.3.2 Numerical analysis of flow pattern and concentration distributions of gas from a heaterThe numerical analysis of indoor air environment such as air quality, temperature, humidity and flow patterns, was conducted for different types of ventilation. Suction ventilation system was fond to be effective for comfortable temperature distributions and low concentration of pollutants.19994) Development of technologies for improving the indoor environment4.1 Removal of VOCs liberated from Wooden Materials using TiO2 Nano-size Particles on PTFE Sheet Activated by UV IrradiationIt confirmed that VOCs is removed by adsorbing and oxidizing VOCs on TiOィイD22ィエD2 particles surface after irradiating UV at the net-like sheet made from PTFE which using TiOィイD22ィエD2 nano-size particles.4.2 Fundamental study on gaseous hazards removal by TiOィイD22ィエD2 Nano-size aerosolBy UV irradiation, aerosol of TiOィイD22ィエD2 nano-size particles was activated to remove effectively gaseous hazards such as VOC and mercury. It was confirmed that mercury could be oxidized and deposited on TiOィイD22ィエD2 surface, effectively. SiO2 aerosol reduced the removal efficiency because of the completion of water with TiOィイD22ィエD2 required for the activation. Less
