太阳辐射对不同建筑群产生温升效果的探讨

Discussion about outdoor air temperature rise of different building blocks under the effect of solar radiation

介绍了建筑群温度变化的数学模型,并利用该模型模拟了济南某小区在四种不同工况下,太阳辐射作用引起的温升情况,对不同建筑密度、下垫面材料、自然通风风速的影响进行了比较。结果表明改变下垫面条件,加强自然通风可改善“城市热岛”效应。

A mathematical model that describes building block's temperature variations is introduced, and air temperature rise under the effect of solar radiation for four different blocks in Jinan is simulated. The effects of building density, condition of the urban canopy layer and natural ventilation speed are compared. The result shows that changing condition of the urban canopy layer and enhancing natural ventilation speed can help improving heat island effect.
