遵义市办公建筑自然通风潜力研究

Research on Natural Ventilation Potential of Office Buildings in Zunyi

作为一种有效的通风方式,自然通风不仅能够减少能耗、降低污染,而且带来的新鲜空气也有利于人的心理和生理健康。对于住宅建筑,开窗通风降温是一种惯常做法,但对于办公建筑,由于其较大的内部热负荷,较小的围护结构比例,自然通风的应用并不具有普遍适应性,存在一定的地域差异。为了研究遵义地区办公建筑采用自然通风的潜力,以遵义市典型年气象参数为依据,首先绘制四季风玫瑰图,整理并分析全年风速分布,然后采用度时法,计算遵义地区办公建筑的自然通风潜力。

Natural ventilation,as an effective way of ventilation,not only can reduce energy consumption and pollution,but also the fresh air brought by natural ventilation is beneficial to people＇s mental and physical health.For residential buildings,opening the window to cooling is a kind of practice.However,office buildings own large internal heat load and small envelope proportion,which result in that the application of natural ventilation is not universally adaptive.In order to study the natural ventilation potential of office buildings in Zunyi,based on the typical meteorological parameters,firstly this paper drew the wind-rose diagrams of four seasons,then organized and analyzed the annual wind speed distribution,finally calculated the natural ventilation potential of office buildings with Degree-hours.
