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

应用自然通风可以在实现建筑节能的同时提高室内空气品质。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。并用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。

The application of natural ventilation can improve the indoor air quality in the implementation of building energy efficiency at the same time. In this paper,taking a typical apartment building as the research object,Using DeS T to simulate natural ventilation,analyzing energy saving potential of natural ventilation in severe cold area building to obtain potential time of natural ventilation. And calculate the comfort temperature range,in this range 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,use Airpak to simulate the distribution of indoor temperature,wind,PM V. Finally,reach a conclusion that howmuch energy the building can save when using natural ventilation instead of air conditioning.
