摘　　要：沿海地区高大空间建筑有较高的自然通风潜力,采用自然通风可以提高人员热舒适性,同时降低能耗。采用EnergyPlus软件对连云港地区某铁路站房高大空间建筑的自然通风效果进行了模拟计算,并对自然通风切换温度以及运行控制策略进行了分析。在非供暖季,该站房平均总换气量可达到48m^(3)/s,平均总换气次数可达到1.4次/h。与完全采用机械制冷空调系统相比,自然通风+空调系统可以减少467h的空调运行时间,可节省13.1%的能耗。Large space buildings in coastal areas have high natural ventilation potential. The use of natural ventilation can improve the thermal comfort of personnel and reduce energy consumption. The natural ventilation effect of a railway station building in Lianyungang was simulated using EnergyPlus software. Both the switching temperature of natural ventilation and the operation control strategy are analyzed. In non-heating seasons, the average total ventilation rate of the station can reach 48 m^(3)/s,with the average total air exchange rate of 1.4 ACH. Compared with the fully mechanical air conditioning system, the natural ventilation and air conditioning system can reduce the air conditioning operation time by 467h and save the energy consumption by13.1%.
