摘　　要：对冬季建筑物外围护门窗结构冷风渗透耗热量进行理论分析,考虑通过空气渗透和侵入造成的潜热热负荷,并对显热热负荷和潜热热负荷进行逐时计算,将结果进行比较分析。结果表明在冬季供暖空调标准工况下,24h周期内空气渗透造成的潜热热负荷约是其相应显热热负荷的8%。对于高层建筑以及室内温湿度要求较高的建筑,进行采暖负荷设计时有必要考虑这部分潜热负荷。Analyzed theory of air infiltration heating load through building exterior envelope in winter accounting for latent heat load.Seperately calculated the hourly sensible heat load and latent heat load.The conclusion indicated that under the standard condition of heating and air conditioning,latent heat load is about 8% of sensible heat load in 24 hours.So it is necessary to consider latent heat load when caculating heating load for high-rise building or that ones with more require on temperature and humidity.
