摘　　要：以沈阳某超高层住宅电梯井为例,运用CFD模拟方法探究不同通风方式对电梯井的影响。设置自然通风开孔面积为1 m^(2),不同开孔距离分别为9 m、30 m;机械通风的风量为3600~10800 m^(3)/h。建立理论热压与电梯门两侧压差的关系,实际测量不同室外温度下电梯门两侧压差,分析不同通风方式对电梯门两侧压差的影响。自然通风与机械通风协同送入室外冷风的冷却效果最显著。采用机械通风时,必须控制机械通风的风量和风速,送入最小风量以达到建筑节能要求。Taking a super-high-rise residential elevator shaft in Shenyang as an example,CFD simulation method was used to explore the influence of different ventilation methods on the elevator shaft.The natural ventilation opening area was set to 1 m^(2),and the different opening distances were 9 m and 30 m,respectively.The air volume of mechanical ventilation is 3600~10800 m^(3)/h.The relationship between theoretical hot pressure and pressure difference between both sides of the elevator door is established,the pressure difference between the two sides of the elevator door is actually measured at different outdoor temperatures,and the influence of different ventilation methods on the pressure difference between the two sides of the elevator door is analyzed.Natural ventilation and mechanical ventilation work together to send cold air to the outdoor cooling effect is the most significant.When mechanical ventilation is used,the air volume and wind speed of mechanical ventilation must be controlled,and the minimum air volume must be sent to meet the requirements of building energy saving.
