夏季阴天户外空间表面温度测试及分析

Investigation and Analysis of Temperatures on Outdoor Building Surface in Cloudy Summer Days

以我国东南沿海某居住小区为研究对象,用红外非接触测温技术测试夏季阴天户外空间周围建筑物各立面温度分布和变化,以及常用的水泥和草地地面在有或无遮挡时的温度变化．用气候监测仪测试全天太阳辐射、空气温度和相对湿度、风速和风向,了解居住小区多种热环境因素的变化．通过测试结果分析,为居住小区户外空间的热环境设计提出相应建议．

Taking a residential eommunity located in the southeast coastland of China as the research object to study the outdoor thermal environment, the noncontact infrared thermometers were used to record the temperature distributions and variations on different outdoor building facades in cloudy summer day. The temperature variations on the gross ground and concrete ground shaded or unshaded, are also investigated. The Casella NOMAD weather station system was used to automatically monitor the outdoor climate parameters such as solar radiation, air temperature, relative humidity, wind speed and wind direction. Discussing and analyzing the recorded results, some helpful suggestions are presented for the design of the outdoor thermal environment.
