对重庆通风现状进行调研,了解到居民希望尽可能利用自然通风改善室内热环境。采用现场测试的方法,得出重庆自然通风在改善室内热环境方面有一定的实际效果。利用PMV修正模型作为分析依据,根据规范、重庆地理气候结合实测和模拟结果寻找不同气流速度对应的可接受室内热环境的温、湿度上限,分析不同气流速度对可接受的温、湿度的影响。
Through the investigation on the present status of ventilation in Chongqing City, it is known that the residents wish to use as much as possible natural ventilation to improve indoor thermal environment. By using field test method, it is obtained that the natural ventilation in Chongqing City has a certain practical efficiency in improvement of indoor thermal environment. The temperature and humidity upper limits of an acceptable indoor thermal environment at different air velocities are found by using PMV correction model as analysis basis and based on the standard, the local geographic climate, the measured and simulated results. The influence of different air velocities on the acceptable temperature and humidity is analyzed.
