基于Amesim的汽车空调系统能耗研究

Research on Energy Consumption of Automotive Air Conditioning System Based on Amesim

车载空调系统作为现代汽车必不可少的辅助配件,其重要性不言而喻。但空调系统的运行对整车的能耗有非常的大影响。为探究空调系统的运行对整车能耗的影响,必须先研究空调系统的能耗变化,本文以某款车载空调系统为例,先建立了车室热负荷模型,并对影响空调热负荷的要素进行了研究分析。针对计算出的热负荷公式匹配空调系统的各个部件,再通过Amesim软件建立了变排量空调系统的模型,并研究不同环境温度对空调系统运行功率的影响,进行汽车空调系统的仿真分析和研究。研究结果表明,随着室外环境温度的变化,车室热负荷随之变化,空调系统为使车室温度达到稳定,会相应的控制压缩机改变其排量,从而压缩机的能耗也会随之变化。

The importance of vehicle air-conditioning systems as an essential accessory for modern cars is self-evident.However,the operation of the air conditioning system has a great impact on the energy consumption of the entire vehicle.In order to investigate the impact of the operation of the air-conditioning system on the vehicle energy consumption,we must first study the energy consumption changes of the air-conditioning system.This article uses a vehicle air-conditioning system as an example.The elements were studied and analyzed.Aiming at the calculated heat load formula to match each component of the air-conditioning system,a variable displacement air-conditioning system model was established by Amesim software,and the influence of different ambient temperatures on the operating power of the air-conditioning system was studied.Simulation analysis and research of the automotive air-conditioning system.The research results show that as the outdoor ambient temperature changes,the heat load of the cabin changes accordingly.In order to stabilize the cabin temperature,the air-conditioning system will control the compressor to change its displacement accordingly,so the energy consumption of the compressor will also vary with the change.
