严寒地区某公寓自然通风效果模拟分析

Simulation of Natural Ventilation Effect of Severe Cold Area Building

本文以某典型公寓建筑作为研究对象,用DeST对其自然通风进行模拟,分析严寒地区建筑的自然通风节能潜力,得出严寒地区自然通风潜力较大时间段,计算出自然通风有效性。应用DeST分别计算出过渡季节开窗与不开窗条件下的耗冷量,得出自然通风节能率。为了验证上述结论,用Airpak对典型时间、典型房间室内温度场、风速场、PMV分布进行模拟。

Taking a typical apartment building as the object, the natural ventilation was simulated by DeST, and the energy saving potential of natural ventilation in severe cold area building was analyzed to obtain potential time of natural ventilation. The comfort temperature range was calculated, in which natural ventilation can take the place of air conditioning. The energy saved will be taken as part of the energy saving effect of natural ventilation. In order to verify the above conclusions, the distribution of indoor temperature, wind, PMV were simulated by Airpak.
