摘要
本文针对中华人民共和国汽车行业标准(QC/T499-2010)《保温车、冷藏车技术条件及试验方法》新加入的行驶调温性能试验,提出一套试验方案。试验把调温阶段和开门卸货过程相结合,能较真实的反映了冷藏车在实际运行过程中的厢体温度变化,得到三温区冷藏车在实际运行过程中各厢体的内部降温曲线,并就开门过程中漏冷严重的情况对本车改造提出建议。
This paper make a reference program according to the reality of multi-temperature refrigerated vehicle and temperature adjustment during vehicle moving test in QC/T449-2010 of People′s Republic of China.The program combines the phase of temperature adjustment with the process of loading/unloading during the realistic scenarios.At the same time,it also reflects the temperature variation and gets the cooling curve in different compartments.At last,according to the fearful cool leakage,some advices are given.
