中文摘要：

在分析热平衡法（HBM）和权重系数法（WFM）等热力系统仿真方法基础上，选择热平衡法为研究手段，建立了包括气象模型、围护结构热平衡模型、制冷系统性能模型和车内空气热平衡模型在内的冷藏车热状况及能耗分析模型。通过联立求解的方式，即可最终掌握冷藏车在实际运行中的热性能和能耗状况。随后，以B23型机械冷藏车（北京-广州）为例进行了模拟与分析，并将仿真结果与B10B型机械冷藏车实测数据（廉江-乌鲁木齐）进行对比。结果表明上述模型能较好的反映冷藏车热特性，可为冷藏车热状况的整体评价和优化控制提供依据。

英文摘要：

The heat balance model （HBM） was selected to establish the simulation models of refrigerated car heat condition and energy consumption including the climate model, the enclosure heat transfer model, the model of the refrigerating system performance, and the heat balance model of the air in the vehicle. Then, the simulation and analysis were performed for a real B23 type refrigerated car running from Beijing to Guangzhou at a speed of 120 kin/h, and the predictions were compared with the test data of a B 10B type refrigerated car running from Lianjiang （Guangdong Province） to Wulumuqi （Xinjiang Province）. The results obtained by the model showed good consistency with the experimental data.
