Analysis of Fresh Air Volume of Air-conditioning System for Railway Vehicles

The relevant standard requirements both in domestic and abroad provide the basis for designing airconditioning system of railway vehicles present. However,there are great differences in the fresh air volume indicators among different standards requirements,and the requirements of each vehicle procurement contracts are also different. The design of air-conditioning become difficult above these. In this paper,the fresh air volume of different type railway vehicles is analyzed from health and equipment electricity consumption according to the railway vehicles air-conditioning system standard requirements in domestic and abroad. Some advises for designing air-conditioning system of railway vehicles through the fresh air volume calculation and comparison for domestic air-conditioning system of railway vehicles was provided.
