摘要
建立太阳照射和自然通风条件下建筑与室内、外环境的空气平衡方程与热平衡方程,以及沿围护结构厚度的非稳态一维导热方程,求解得到建筑围护结构和室内空气的温度。选取广州夏季某一天的气象参数,计算围护材料分别采用钢筋混凝土、灰砂砖砌体、浮石混凝土、橡木和平板玻璃情况下,从7时至19时一单室建筑围护结构及室内空气的温度。
The balance equations of air mass and heat energy in natural ventilation condition for building exposed in the sunlight were established.Also,the equation of unsteady and one dimensional conduction along the wall thickness was established.The equation groups were solved to give the quantity of natural ventilation,temperatures of the wall and air in the room.As the computing sample,the temperatures of the wall and air in one separated room constructed with steel concrete,sand-lime brick,pumice concrete,oak and glass,from 7:00 to 19:00 on one summer day,were computed.The meteorologic parameters in typical year of Guangzhou were used.
