            摘要:

             以嚴寒地區某機場航站樓為模型,分析了其在各氣候區典型城市設計工況下的空調負荷構成,進而分析了圍護結構熱工參數、室內設計溫度、人員密度、新風量指標等因素對冷熱負荷的影響程度,并對系統負荷和末端負荷的差異進行了探討。結果表明:圍護結構負荷、新風負荷和人員負荷是空調負荷的主要組成部分,人員密度和新風量指標對空調負荷影響較大,不同氣候區各因素對空調負荷的影響程度有所差別,設計冷熱源和末端設備時宜對空調負荷進行適當修正。

            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.
