摘　　要：针对重型车辆车载空调引起的附加油耗和污染物排放问题,分析不同温度条件下重型车辆车载空调开启和关闭对油耗及污染物排放的影响,并基于中国重型商用车辆行驶工况(CHTC)进行了转毂测试,结果表明:高温条件下空调附加油耗为7%左右,较常温条件下空调附加油耗(5%左右)更高;重型车辆质量越大,空调系统对总体油耗的影响越小;空调开启可降低NO_(x)排放量,且高温条件下的NOx排放量较常温条件下低;空调开启会造成粒子数量(PN)和CO_(2)排放量提高。For the additional fuel consumption and pollutant emissions caused by heavy-duty vehicle air conditioning,this paper analyzes the effects of turning on or off air conditioning on fuel consumption and pollutant emissions under different temperature conditions.Dynamometer test is performed based on China Heavy-duty commercial vehicle Test Cycle(CHTC).The test results show that the additional fuel consumption of the air conditioning is about 7%under high temperature,5%higher than that under normal temperature.The larger the weight of a heavy-duty vehicle,the smaller the impact of the air conditioning system on fuel consumption.Turning on the air conditioning can reduce NO_(x) emission,and NOx emission under high temperature is lower than that under normal temperature.Turning on the air conditioning will cause an increase of Particle Number(PN)and CO_(2) emissions.
