摘要:
以某地铁车辆客室的空调通风系统为研究对象,模拟车辆在环境温度为33 ℃下客室内空载时气流组织的平均温度和微风速。仿真结果表明,空载情况下客室内的平均温度为24.37 ℃、最大微风速为0.28 m/s,符合EN 14750标准的要求。将仿真结果和实车的空调试验结果数据进行对比分析,验证了仿真分析的准确性。
Abstracts:
The air conditioning and ventilation system of a metro vehicle is taken as the research object, the average temperature and the breeze speed of air flow are simulated when the ambient temperature is 33 ℃ and the passenger compartment is empty. The simulation results show that when the passenger compartment is empty, the average temperature is 24.37 ℃ and the maximum wind speed is 0.28 m/s, all meets the requirements of the EN 14750 standard. The simulation results are comparatively analyzed with the air conditioning test data of a real vehicle, and the accuracy of simulation analysis is verified.
