摘　　要：高原寒冷地区因其独特的地理条件和海拔高、气压低、气温低,冬季漫长等特点,使得建筑供暖期较长,供暖能耗占建筑总能耗的比例较高。对于高原寒冷地区大空间建筑,气候条件对不同的供暖末端性能的影响,前人研究较少。首先,分析了气候条件对候机楼中常用的供暖末端在高海拔地区供暖能耗的影响;其次,基于日喀则某候机楼低温地板辐射供暖系统,通过eQUEST软件模拟和现场实测两种方式,对系统能耗和室内温度分布进行分析,并与拉萨某候机楼风机盘管供暖系统进行对比。结果表明,低温地板辐射供暖系统比风机盘管供暖系统年节约能耗5.6%,即低温地板辐射供暖末端在高原寒冷地区更为适用。Due to its unique geographical conditions,plateau cold areas has the characteristics of high altitude,low air pressure,low temperature,long winter,which makes a long heating period and high proportion of building energy consumption.However,the research about the influence of climatic conditions on the performance of the terminals in plateau cold areas is less.First,this paper analysis the impact of atmosphere on heating energy consumption of the common heating devices used in the terminals in t plateau cold area;then,study on the low-temperature radiant floor heating system of a terminals in Shigatse and analysis its system energy consumption and indoor temperature distribution compared with the FCU heating system of a terminals in Lhasa by both eQUEST stimulation and the field measurement.The results show that the low-temperature floor radiant heating system is 5.6%less energy consumption than the fan-coil heating system,that is,the low temperature floor radiant heating system is more suitable for the plateau cold areas.
