航站楼空调送风末端系统经济性分析和优化模型

为提供空调末端形式的优化设计依据，提出了空调末端系统运行成本的主要影响因素，分析确定了影响因素的变化范围，并建立了空调末端系统运行多参数经济分析模型，分析了各参数的影响程度。结果表明，运维成本占比不高，人工成本的差别不影响成本变化趋势，但运行时长对运行成本的影响较大，运行时长越长，机组效率的影响越大。小风量分布式末端机组经济节能性好，控制策略灵活。整体式空调机组具有较广的适应性，对于大部分航站楼的空调末端系统都是最优解。适合对于电价政策复杂的情况，应具体问题具体分析，代入模型得出准确的优化方案。该研究为交通建筑空调末端系统的优化运行及设计提供参考。

Economic analysis and optimization model of air-conditioning air supply terminal system in the airport terminal

A multi-parameter economic analysis model is established and the influence degree of parameters is analyzed for optimal design of air conditioning terminal system. The results show that the proportion of operation and maintenance costs is not high,the difference in labor costs does not affect the trend of cost changes, but the duration of operation has a greater impact on operation costs. The longer the operation time, the greater the impact on the unit efficiency. Distributed terminal units with small air volume are economical and energy-saving, and the control strategy is flexible.The integral air conditioning unit has wide adaptability and is the optimal solution for the air conditioning terminal system of most terminals. For the complex situation of electricity price policy, specific problems should be analyzed in detail, and an accurate optimization plan should be obtained by substituting into the model. The research provides a reference for the optimal operation and design of the air-conditioning terminal system in traffic buildings.
