摘要

为提高冷藏车的隔热性能，对采用基于高反射技术隔热卷材的冷藏车保温性能进行测试并分析能耗，获得了箱体热通量、箱内空气降温速度及均匀性等情况。实验结果表明：张贴高反射隔热卷材可使箱体外壁面峰值温度降低23.6 ℃，使通过车顶进入车厢内的热量减少。在无制冷的情况下，热通量降低比例为46.3%；在设定5 ℃的冷藏温度下，下降比例为16.7%~26%。隔热卷材使车厢外壁温度均匀性提高至1.12，内部均匀性提高至1.68；同时在制冷系统启动后可以更快达到设定温度，同时更容易维持较低温度。有隔热卷材车厢可使压缩机工作频率降低9.1%，从而节省能耗，达到良好的节能效果。研究结果可为冷链运输装备节能运用提供新思路，对有隔热要求的粮库、冷库等设施亦具有参考意义。

Abstract

Thermal insulation is a crucial performance indicator for cold-chain transportation equipment. Improving the thermal insulation performance can effectively reduce transportation energy consumption and

thus

lower costs. To enhance the thermal insulation performance of refrigerated trucks

this study conducted tests

analyzed the insulation performance using high-reflectivity insulation materials

and analyzed energy consumption. The study obtained data on the heat flux through the box

air cooling rate inside the box

and temperature uniformity. The experiments demonstrated that applying high-reflectivity insulation materials reduced the peak temperature of the external wall surface of the box by 23.6 ℃

leading to less heat transfer into the compartment through the roof. In the absence of refrigeration

the proportion of heat flux reduction was 46.3%

while at the set refrigeration temperature of 5 ℃

the reduction ranged from 16.7% to 26%. The insulation material improved the temperature uniformity of the external wall of the compartment to 1.12 and the internal uniformity to 1.68. This simultaneously allows the refrigeration system to reach the set temperature more quickly and maintain a lower temperature more easily. Compartments with insulation materials reduced the operating frequency of the compressor by 9.1%

leading to energy savings and good energy efficiency. The research results provide new insights into the energy-efficient use of cold chain transportation equipment and are relevant for facilities such as granaries and cold storage facilities with insulation requirements.
