室内通风气流组织模拟及评价——以某办公建筑为例
|
摘要
建筑能耗是社会总能耗的主要部分,空调采暖能耗又是建筑能耗大户,因此节约空调采暖的能源消耗是建筑节能的重要手段,而使用被动式自然通风,利用可再生能源,最大限度减少主动式采暖与制冷设备的运行,是减少空调采暖能耗的一种重要方式。选取一栋位于寒冷地区的办公建筑,为优化建筑室内的通风效果,利用软件模拟分析室内通风气流组织,以获得最大的通风节能效果。
Building energy consumption belongs to the main part of the total social energy consumption, and the energy consumption of air conditioning heating is also a large energy consumption of the building. Therefore, saving the energy consumption of air conditioning heating is an important means to save energy in the building, and using passive ventilation and using renewable energy, minimizing the operation of active heating and refrigeration equipment has become an important way to reduce the energy consumption of HVAC. In this paper, an office building located in a cold area was selected to optimize the indoor ventilation effect, and the indoor ventilation air distribution was simulated and analyzed with software to obtain the maximum ventilation and energy saving effect.
