Study on the Problems and Improving Measures for Air Conditioning System of Passenger Rail Car

The reason that supply air is not uniform for traditional air conditioning system of passenger car are analyzed, the design methods of static pressure supply air duct are given. The performance of supply air is tested for several type static pressure supply air duct,experimental data indicate that if some measures are not adopted, uniformity of supply air of static pressure supply air duct is not good. It is necessary to get good supply air uniformity by designing reasonable construction of static pressure supply air duct. To further improve performance of supply air duct for air conditioning, some steps are introduced.
