摘要
根据建筑群热时间常数(Cluster Thermal Time Constant,CTTC)模型,分别对黑白屋顶吸收辐射所引起的不同温升效果进行了模拟计算。结果显示:(1)屋顶对天空的长波辐射引起的温降远小于屋顶吸收辐射所引起的温升;(2)不同吸收率的黑白屋顶的温升效果差异比较明显。本文的研究表明:"白屋顶"计划对降低城市热岛效应确有一定程度的作用。
According to the thermal time constant of the buildings （ Cluster Thermal Time Constant, CTTC ） model, the different temperature effects caused by absorption of radiation on black and white roof were simulated. The simulation results show that： （ 1 ） The roof of the sky long-wave radiation caused temperature drop is much smaller than the roof to absorb the radiation caused by the temperature rise; （2） Black and white roof of the different absorption rate of temperature rise effect differences. In summary, this paper believes that ＂white roofs＂ program reduce the urban heat island effect to a certain extent degree.
