EXPERIMENTAL STUDY ON THE PERFORMANCE OF EVAPORATOR AND CONDENSER HEAT EXCHANGERS IN A TRAIN-USED AIR CONDITIONING GROUP

摘要

This paper presents the measuring procedure, the experimental results and the evaluation for the air conditioning group used in a high-speed train compartment. The target of these tests is to determine the evaporator and condenser performance at the given design conditions. The finned coil condenser and evaporator are installed in air ducts and to control the flow going through the heat exchangers as recommended for the air-heated and air-cooled heat exchangers specific test (ASHRAE Standard 33-1978R, 1999, European Standard EN 1216, 1999). The evaporator and the condenser of the air conditioning group are tested separately in order to have the better control for reaching the design conditions. A simulation model is also developed here to standardize the test results to the required conditions.
