Design of Compressor Displacement Testing System for Air-conditioner of Air-conditioned Passenger Train

According to china standards ,an air displacement test of compressor should be made when the air-conditioned passenger train is maintained. In order to improve efficiency of maintenance , this article has studied the test system of air-conditioner compressor which is a part of air-conditioned passenger train . According to the request of the maintenance regulation, this article had designed the test-bed of air-conditioner compressor. And ,to meet the actual need of maintenance, the corresponding testing software system was designed. After this system is put to use, we could enhance maintenance efficiency greatly.
