Analysis on Temperature Field of Refrigerated Car in Cold Chain Logistics

The paper analyzed the simulating ways about heat system of refrigerated car in cold chain logistics. Heat balance model was chose as the analyzed tool. An analytic system was set up for simulating the heat condition of refrigerated transportation. The system includes climate model outdoors, heat transfer model of the insulated layer, exterior and interior surface heat balance model of insulated layer, heat balance model of the air in the vehicle, etc. Then, a real refrigerated car was simulated and analyzed from Beijing to Guangzhou, and verified by a real data of refrigerated car. The results obtained from the model show good consistency with the experimental data. The model properly reflects the heat condition of car and provides a basis for holistic evaluation and optimum controlling on refrigerated car in cold chain logistics.
