摘要
本文采用Block模型对一室内的热环境进行理论计算,在垂直方向上空间被划分为五个区域,建立风量与热平衡方程进行计算,由此可以得到由于自然对流作用而产生的沿壁面上升或下降的气流以及室内垂直温度分布。此外,本文还利用商用软件Airpak以实测壁面温度作为第一类边界条件对室内的热环境进行了数值模拟,分析了室内垂直方向的温度分布,并采用国外实验数据进行验证。结果表明,两种方法得到的结果与实验测试结果基本一致.
The Block model was used in the present work for the prediction of the vertical temperature distribution in a building.The space is vertically divided into 5 zones.According to the given interior wall temperatures,the ascending and descending currents along the vertical walls generated by natural heat convection are evaluated,and the vertical temperature distribution can be obtained by solving the equations of airflow balance and that of heat balance in all zones.The problem was also simulated numerically with the commercial software Airpak,and the results coincide with the experimental data from literature.
