Abstract：To reduce the high energy consumption of air conditioning systems in rail transit vehicles and achieve precise testing and standardized evaluation,taking the trains of Chongqing City metro line 6 as the object,a combination of numerical calculation and experimental testing is adopted to compare the energy consumption testing and calculation methods of air conditioning systems in rail transit vehicles,such as orthogonal experiment method,typical sky method and weight method,and to provide the applicable scenarios of each method.The results show that the orthogonal experiment method,the typical sky method and the weight method can all obtain highly accurate energy consumption of the air conditioning system of rail transit vehicles.The orthogonal experimental method has high accuracy and can establish the energy consumption prediction relationship.The typical sky method is applicable to the simulation calculation of energy consumption of air conditioning systems in rail transit vehicles.The working conditions of the weighting method are uniform and stable,and it is easy to implement in the laboratory.
