航站楼建筑空调负荷特征及影响因素分析
Analysis of air conditioning load characteristics and influencing factors in terminal buildings
摘要：
以严寒地区某机场航站楼为模型，分析了其在各气候区典型城市设计工况下的空调负荷构成，进而分析了围护结构热工参数、室内设计温度、人员密度、新风量指标等因素对冷热负荷的影响程度，并对系统负荷和末端负荷的差异进行了探讨。结果表明：围护结构负荷、新风负荷和人员负荷是空调负荷的主要组成部分，人员密度和新风量指标对空调负荷影响较大，不同气候区各因素对空调负荷的影响程度有所差别，设计冷热源和末端设备时宜对空调负荷进行适当修正。
Abstract：
Taking an airport terminal building in severe cold zone as a model, analyses the air conditioning load composition under typical urban design conditions in various climatic zones, and then analyses the influence of envelope thermal parameters, indoor design temperature, personnel density, outdoor air rate index on cooling and heating load, and discusses the difference between system load and terminal load. The results show that the envelope load, outdoor air load and personnel load are the main components of air conditioning load, and the personnel density and outdoor air rate index have a great impact on air conditioning load. The influence of various factors on air conditioning load in different climatic zones is different. The air conditioning load should be appropriately modified in the design of cold and heat sources and terminal equipment.
