地铁列车运行产热量计算探讨
Discussion on heat production calculation for subway train operation
摘要：
对列车产热量的详细计算有利于地铁环控系统的设备选型和节能运行,更有利于隧道热量的回收和再利用。本文引述了地铁列车运行产热量的相关计算方法,纠正了部分谬误,并增补了小时行车数、空调和电加热设备同时使用系数等影响因素,进一步细化了列车运行产热量的计算方法。案例计算结果表明:列车启动阻力产热量占比最小,仅为列车总产热量的0.1%;夏季空调产热量占比可达总热量的16.9%～32.5%。
Abstract：
Detailed calculation of heat produced by trains is beneficial to the equipment selection and energy-saving operation of the metro environmental control systems, which is more conducive to the recovery and reuse of tunnel heat. This paper quotes the relevant calculation methods of heat production during subway train operation, corrects some fallacies, adds influencing factors such as the number of trains per hour, the simultaneous use coefficient of air conditioning and electric heating equipment, and further refines the calculation method of heat production during train operation. The calculation results of the case show that the heat produced by train starting resistance accounts for the smallest proportion, only 0.1% of the total heat produced by the train. The heat produced by air conditioning in summer can account for 16.9% to 32.5% of the total heat production.
