Research on the design of air conditioning and heating system for an urban rail vehicle exported to Central Asia
The paper takes an urban rail vehicle exported to Central Asia as the research object,analyze and verify the rationality of air-conditioning and heating system design.Through the calculation of vehicle thermal load to determine the single cooling and heat capacity,complete the design of air conditioning and heating system.The air distri-bution in Mc1 vehicle is simulated by using computational fluid dynamics(CFD)software FLUENT,and the temperature field,velocity field and other indicators are studied by comparing the requirements of EN 14750.Through the static test of ventilation and heating performance,each index meets the standard requirements,which verifies the ra-tionality and scientificity of the system design.
