基于实测数据的地铁车站公共区空调负荷设计指标优化
Optimization of air conditioning load design index for public areas of subway stations based on field measured data
摘要：
在设计过程中，空调负荷预测的准确性对于整个空调系统的合理性及运行节能均起着关键性作用。本文基于厦门地铁1号线某地铁车站公共区空调负荷、站内环境、设备发热量、新风量及出入口渗风量实测结果，对车站照明、广告照明、自动售票机、自动检票机、安检设备、电梯、人员、新风及出入口渗风负荷的特性进行了分析，对地铁车站空调负荷设计计算中的关键问题进行了探讨，给出了各项负荷的实测结果及设备散热负荷指标，为地铁车站空调负荷设计计算提供参考。
Abstract：
In the design process of the air conditioning system, the accuracy of air conditioning load forecasting plays a key role in the rationality of the entire air conditioning system and the saving of operating energy consumption. Based on the field test results of air conditioning load in the public area, internal environment, equipment heat generation, outdoor air volume, and air infiltration at the entrance and exit of a subway station in Xiamen Metro Line 1, this paper analyses the load characteristics of station lighting, advertising lighting, automatic ticket vending machines, automatic ticket checking machines, security inspection equipment, elevators, passengers, outdoor air, and air infiltration loads at the entrance and exit, and discusses the key issues in the calculation of air conditioning load of subway stations. The measured results of various cooling loads and the equipment heat dissipation load index are given, which provides references for the calculation of the air conditioning load of subway stations.
