受树冠遮庇时建筑物外表面辐射换热的计算

CALCULATION METHOD OF BUILDING'S RADIATION-HEAT TRANSFER INFLUENCED BY GREEN PLANT

树冠对建筑物形成的遮庇会影响到建筑物外围护结构的辐射换热量 ,从而影响建筑物的室内温湿度和建筑物的能耗。量化研究此类问题对建筑物节能具有重要意义。该文尝试以传热学理论结合生态学知识 ,对树冠遮庇下建筑物外围护结构辐射换热强度的计算公式进行了理论推导 。

More and more trees are planted in residential district for concerning of the environment.The building's radiation-heat transfer,temperature,humidity and building's heat & cold loads have been changed by hiding of the foliage,which is very important for saving building's energy consumption.Based on the heat-transfer theory and the knowledge of ecology,the radiation-heat strength formulas of the building which is hided by foliage are found. Theory results were tested and verified.
