摘　　要：与其他公共建筑不同,大型机场航站楼存在大量的高大空间、室外开口,内部大量客流随时都在动态变化,空调系统按旅客流程进行间歇运行,导致航站楼的冷热负荷在时空上分布不均。本文以北京大兴国际机场航站楼为例,通过IES动态负荷模拟软件,对比分析了大空间分层、开口的风压系数、客流时序性和统计时间间隔、空调系统间歇运行对负荷的影响,计算结果表明,这些因素对冷、热负荷峰值的偏差在3.32%~23.02%的范围不等,对全年耗冷耗热量的偏差达-22.5%~18.83%,说明以上影响因素对冷热负荷均有影响,大型机场航站楼冷热负荷计算时需要考虑这些因素。Different from other public buildings, the large airport terminal has a large number of tall spaces and outdoor openings. The large number of internal passenger flows are changing dynamically at any time, and the air conditioning system also operates intermittently according to the passenger flow, resulting in uneven distribution of cooling and heating loads in time and space. Taking Beijing Daxing International Airport terminal as an example, this paper compared and analyzed the effects of large space stratification, wind pressure coefficient of opening, passenger flow timing and statistical time interval, intermittent and local operation of air conditioning system on load through IES energy simulation software. The calculation results show that the deviation of these factors to the peak value of cooling and heating load ranges from 3.32% to 23.02%, and the deviation to the annual cooling and heating consumption ranges from-22.5% to 18.83%, indicating that the above influencing factors have an impact on the cooling and heating load, which should be considered in the calculation of cooling and heating load of large airport terminals.
