【英文篇名】 Discussion on air temperature variation of building blocks caused by solar radiation 【作者中文名】 王菲; 肖勇全; 【作者英文名】 By Wang Fei~★ and Xiao Yongquan★Shandong University of Architecture and Engineering; Jinan; China; 【作者单位】 山东建筑工程学院; 【文献出处】 暖通空调, Hv 热岛效应; 太阳辐射; CTTC模型; 【英文关键词】 outdoor thermal environment; heat island effect; solar radiation; CTTC model; 【摘要】 介绍了建筑群温度变化的数学模型,模拟了济南某小区在四种不同工况下太阳辐射引起的建筑群的温升情况,比较了建筑密度、下垫面材料、风速对建筑群温升的影响,结果表明,改变下垫面材料和增强自然通风可改善城市热岛效应。 【英文摘要】 Presents the mathematical model of temperature variation of building blocks. Simulates the air temperature variation of a quarter in Jinan under four different conditions. Compares the effect of the building density, underlying materials and air velocity. The results show that changing the underlying materials and enhancing natural ventilation can improve heat island effect.
