基于底盘测功机的整车空调功率研究

Research on vehicle air conditioning power based on chassis dynamometer

随着油价的不断上涨,用户对车辆油耗的关注度不断的提升。空调系统作为影响整车油耗的一个重要因素,也越来越受到客户的关注。而空调系统的零部件级测试结果并不能真实的反映该系统在整车上的功率消耗。通过在底盘测功机上进行整车空调功率研究试验能减少许多不可控因素对试验结果的影响。文章通过在底盘测功机上对某卡车进行空调功率测试试验,对测量车辆的空调功率进行测量,阐述底盘测功机在整车空调功率研究上的应用。

As oil prices rise, user focus on automotive fuel consumption continues to improve.Air conditioning system is an important factor to affect vehicle fuel consumption, more and more attention by the customer. But the test results of the components of the air conditioning system can＇t truly reflect the power consumption of the system.Through the research on the chassis dynamometer, the influence of many uncontrollable factors on the test results can be reduced.In this paper, the power test of a truck is carried out on the chassis dynamometer, measurement of air conditioning power of vehicle, to application of chassis dynamometer in the research of vehicle air conditioning power is described.
