摘　　要：为了分析燃油汽车空调节能技术在油耗工况的效果,在整车空调降温试验的基础上,建立一维空调仿真模型。针对WLTC的车速特点,分析燃油汽车空调性能提升的方向,并着重分析了同轴管技术,以及提高蒸发器温度的控制策略的节能效果。结果显示,增强乘员舱和空调箱的隔热性能是提升空调性能和降低空调油耗的有效措施;在油耗工况中,同轴管技术对油耗和空调性能提升的效果不明显;而提高蒸发器温度的控制策略对降低油耗的效果明显,并且成本几乎为0。In order to analyze the performance of oil-fueled automobile air-conditioning energy-saving technology in fuel consumption conditions, a one-dimensional air conditioning simulation model is established. The article analyzes the main directions and methods of oil-fueled automobile air-conditioning improvement and energy-saving, and focuses on the energy-saving effect of the coaxial tube technology and the control strategy to increase the temperature of the evaporator. The results show that enhancing the thermal insulation performance of the passenger compartment and the air-conditioning box are effective and economical methods to improve air-conditioning performance and reduce fuel consumption. However, the coaxial tube technology has no obvious effect on fuel consumption and performance improvement. The control strategy of increasing the temperature of the evaporator has obvious effects on reducing fuel consumption, and the cost is almost zero.
