通过仿真计算的方法,分析比较了列车空调机组增加新风量时全热交换器的运行性能。结果表明:直接增加新风量不可行,应用全热交换器后空调机组的出风温度满足要求,并且节能效果明显。
Through the method of simulation calculation, the operation performance of the total heat exchanger when the train air-conditioning unit increases the fresh air volume is analyzed and compared. The results show that it is not feasible to directly increase the fresh air volume. The air temperature of the air conditioning unit after the application of the full heat exchanger meets the requirements, and the energy saving effect is obvious.
