Analysis on air supply duct of the air conditioning system on metro vehicle;

The air supply principles,structural features of the static pressure air supply duct are described.

Development of the supply air duct test stand for air conditioning system on passenger cars;

In this paper the static pressure uniformity in the static pressure chamber of supply air duct is studied by means of experiments,and its coefficient is derived.

In this paper the supply air uniformity of different types of static pressure supply air duct is studied andthe experimental result shows that the supply air uniformity of traditional static pressure supply air duct isn t ideal.

Hence, for improving the uniformityof air supply and the performance of the duct, it is of great importance to studythe rules of resistance distribution in static pressure air supply duct.

By developing the feature test bench of air supply duct for railwayair-conditioned coach, this paper carries out in emphasis the analysis andstudies on air supply control and measurement system, air volume, staticpressure and resistance system in both air supply end and air supply duct.

The reasons that supply air rate is not uniform by using static pressure air supply duct inside the passenger cars are presented.

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.
