自然通风作用下生态建筑热环境测试与数值模拟

以上海地区一实际生态建筑为例，进行一系列的实际测试，并以测试结果为边界条件，应用零方程模型进行了数值模拟。研究结果表明，利用数值模拟的方法能够很好地预测室内热环境，同时在过渡季节利用自然通风能有效地改善室内热环境，较好地满足舒适性要求。

Measurements and Numerical Simulation of Thermal Environment in an Ecological Building with Natural Ventilation

The present research work focuses on the numerical simulation of natural ventilation of an ecological building in Shanghai. In order to evaluate the performance of the ventilation systems of the building,a series of measurements of thermal environment in the building were carried out. The natural ventilation condition was chosen as the calculation example. The real measurement conditions were used in the simulation. Numerical results agreed well with the measured vertical temperature distribution inside the building and the natural ventilation can effectively improve the indoor thermal environment and satisfy the demand of human thermal comfort in transition seasons.
