An automotive air conditioning energy consumption test methods

The present invention discloses an automotive air conditioning energy consumption test method, comprising: providing a car can simulate actual operating conditions of the chassis dynamometer, and a place to be installed in the vehicle air-conditioning system test on the chassis dynamometer; using a chassis dynamometer power absorption values ​​were measured in open air conditioning system is running and the vehicle is not in the power absorption air conditioning system when the vehicle is turned on; difference value calculating two kinds of power absorption dynamometer is measured, the absolute value of the difference between the results for the energy consumption of air conditioning systems. Compared with the prior art, this test method the vehicle chassis dynamometer simulate actual use conditions accuracy and improve the measurement results and the measurement results of the energy consumption of air conditioning systems close to the actual energy consumption of the vehicle environment, It has important reference value for energy research and match the vehicle.
