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

19981）建筑木质材料中VOC的传输机制和分布及其排放1.1建筑木质材料中VOC的排放及其传输机制测定了建筑木质材料中VOC的组分和浓度分布。在不同材料表面温度下，测量了材料表面VOC的释放速率。研究发现，排放率随温度的升高而增加，随部件和建筑材料的变化而变化。2）室内空间中颗粒物的产生2.1步行运动对地板表面粉尘再悬浮的影响测量了不同步行速度下步行引起的地板粉尘再悬浮量。3）室内空气流场的数值分析3.1半封闭空间分层通风的基础研究 ...更多信息 h生热产尘对存在热源和尘源的室内空间进行了流场可视化，并进行了数值分析，讨论了粉尘浓度分层分布的条件。研究发现，当热源的浮力流动占主导地位时，空间中部以下的环流是有效的。3.2加热器气体流态和浓度分布的数值分析对不同通风方式的室内空气环境，如空气品质、温度、湿度和流态进行了数值分析。抽吸通风系统对于舒适的温度分布和低污染物浓度是有效的。19994）改善室内环境的技术开发4.1使用TiO 2纳米去除木质材料释放的VOC紫外光活化PTFE片上的颗粒粒径研究证实了经紫外光照射后，VOCs在TiO_2/D_22/D_2颗粒表面的吸附和氧化作用4.2 TiO_（22）纳米证实了汞可以有效地氧化沉积在TiO_2/D_2/D_2表面。SiO2气溶胶降低了去除效率，因为完成水与TiO ↓ [2] D22的活化所需。少
