Analysis of air conditioning load characteristics and influencing factors in terminal buildings

 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.
