通风时段对合肥某商场建筑能耗影响的模拟研究

Simulation Study on Influence of Ventilation Period on Energy Consumption of Malls in Hefei

以合肥某商场为研究对象,根据DeST能耗模拟软件研究公共建筑不同通风时间下公共建筑的能耗情况及节能效果.为了研究不同通风时段对建筑能耗的影响,拟定了3种通风时段,方案1通风时间为5:00-13:00其他时间不通风,方案2通风时间为13:00-21:00其他时间不通风,方案3通风时间为21:00-5:00其他时间不通风,结果发现方案3负荷最低.为了更好地分析不同通风时段对建筑能耗的的节能情况时,以方案2建筑负荷为基准值,方案3的节能率最高.因此建议在时间段21:00-5:00可通过开窗增大自然通风,从而减少建筑能耗。

Taking a mall of Hefei as the research object,this study analyzes energy consumption and energy saving effect of public buildings under different ventilation time by applying DeST energy consumption simulation software.In order to study the impact of different ventilation periods on building energy consumption,three kinds of ventilation periods were set. The ventilation time of scheme 1 was 5:00-13:00 other times without ventilation,the ventilation time of scheme 2 was 13:00-21:00 other time without ventilated,and scheme 3 ventilation time is 21:00-5:00 other times without ventilation,The results show that the air conditioning load of scheme 3 is lowest ,For the better analyze the energy?saving situation of building energy consumption in different ventilation periods,,Taking the construction load of the scheme 2 as the reference value,the energy saving rate of the scheme 3 is the highest.Therefore,it is recommended to increase the natural ventilation by opening the window from 21:00 to 5:00 for reducing the building energy consumption.
