Studies on methods of reducing thermal pollutionin the urvan area

作为一个人工环境，一个城市也站在自然的反面。Air temper\in the big city such as Fukuoka and Tokyo have been raised about 2 D1cC in these 100 years。这是21世纪最后一半的全球变暖的迹象。这些人是由与人类人口条件相关的增加能源消耗和被混凝土和沥青覆盖的城市结构引起的。后来的人是对迁移的替代，是对蒸发转化的退化造成的;研究的目的就是开发通过结构变化造成的恢复小条件的方法。使用water retentive？amic tile进行的比较。在fare summer days上的比较。在fare summer days上的比较表面温度。这里，陶瓷瓷砖是水平地和垂直地躺在R上 ... More 有6栋建筑物。The temperature difference between those wet？amics and the original conOracle roof surface were about 20 D1 D1cC at noon。湿陶瓷和水稻植物的温度几乎相等于其他植物，但他们的日常时间路线略微取决于时间，如果它是公平的，或者太阳辐射的数量。热平衡和辐射平衡得到了分析。湿陶瓷可以用改变最后的热量来衡量最多的净辐射。下一个，我讨论了仓库的折叠类型的陶瓷屋顶，在那里我可以用平板型屋顶来比较表面蒸发区域。表面温度的内外温度比原来的钢屋顶温度低得多，而且人体内部热量辐射的方向在中午被逆转。内在的热污染得到了很大的改善，在同一时间，平坦和斜坡面的南部和北部蒸发量分别为0.86、0.74和0.46毫米/小时。这些价值观很容易转化为最新的热能，来自热辐射特征的点，湿陶瓷屋顶行为作为热辐射吸收器，而原始的屋顶作为热辐射器。因此，湿陶瓷可以防止人体上的热压力。由于平板陶瓷的退化温度的影响是足够的，所以折叠类型并不总是需要开放的区域。我们可以在城市地区减少大量的热污染，如果我们可以将此方法应用到城市。Less（低）

As the artificial environment, the cities are on the opposite side of the nature. Air temperatures in the big city such as Fukuoka and Tokyo have been raised about 2ィイD1゜ィエD1cC in these 100 years. This is the sign of global warming at the last half of 21 century. Those were caused by the increasing energy consumption associated with condensation of human population and the structure of city covered with concrete and asphalt. The later is the replacement of vegetation to concrete, which brought decreasing of evaportranspiration.The purpose of the study is to develop the methods of recovering of minus condition brought by structural changes. I conducted experimental study on the characteristics of ability evaporative cooling using water retentive ceramic tile.The comparisons of surface temperatures among water-retentive ceramic tiles rice plants and the original concrete roof surface were examined on fare summer days. Here, the ceramic tiles were laid horizontally and vertically on the r … More oof of 6 storied building. The temperature difference between those wet ceramics and the original concrete roof surface were about 20ィイD1゜ィエD1cC at noon. Temperatures of wet ceramics and rice plants were nearly equal each other, but their daily time course changed slightly depending on the time, if it was fare, or the amount of solar radiation. Heat balance and radiation balance was analyzed. The wet ceramics could consume most of net radiation by changing into latent heat.Next, I discussed on the folding type of ceramic roof of warehouse, which can extend surface evaporative area comparing with flat type roof. The surface temperatures outer side and inner side were much decreased than the original steel roof, and direction of heat radiation from human body inside the room was reversed at noon. The inner thermal pollution was greatly improved.At the same time, the amount of evaporation of flat and slopes facing south and north are 0.86, 0.74 and 0.46 mm/h respectively. Those values are easily converted into latent heat energy.From the points of the characteristics of heat radiation, wet ceramic roof acts as heat radiation absorber, while the original roof does as heat radiator. Thus, wet ceramics can avoid thermal stress on human body. As the effect of decreasing temperature of flat ceramics is enough, so the folding type is not always needed for open wide area. We can achieve a lot of decreasing of thermal pollution in urban area, if we can apply this method to the city. Less
