摘　　要：气候增暖不可避免地对与室外气象条件关系密切的自然通风技术具有影响。通过建立单侧通风房间模型,利用天津市市台站1960—2010年逐时气象数据,通过理论计算,从自然通风驱动力和室内热舒适2个方面研究自然通风对气候变化的适应性,以总综合压差和室内热舒适小时数2个指标分别评估了自然通风的应用潜力。总综合压差越大、室内热舒适的小时数越多,自然通风的应用潜力就越大。结果表明随着气候变暖,总综合压差及室内舒适总小时数呈下降趋势,说明天津地区自然通风的应用潜力正变得越来越小。Climate change affects the potential of natural ventilation unavoidably. Used hourly meteorological data from 1960 to 2010 of Tianjin, this paper studied the natural ventilation adaptation to climate change of an assumed single-sided ventilation room from the driving force of natural ventilation and indoor thermal comfort by calculating, evaluated the potential of natural ventilation through the total integrated pressure difference and indoor thermal comfort hours. The greater the total integrated pressure difference, or the more the indoor thermal comfort hours, the better potential of natural ventilation. The results show with the climate change, the total integrated pressure difference and the indoor thermal comfort hours are all reduced, means the potential of natural ventilation is becoming worse and worse.
