摘要

罐式冷藏集装箱是目前运输低温液体的最主要途径，其制冷系统出风口被液罐遮挡，导致罐箱制冷系统能效低，需在有限的安装空间下提升罐箱制冷系统能效。本文提出通过优化冷凝器风道结构与管路排布来减小风道总阻力损失、提升冷凝器风量的思路，来提升系统能效；通过优化出风口形状、分布和尺寸，保证冷凝器的出风口在受到一定遮挡的条件下也能够有足够的风量；通过优化冷凝器管路布置，在保证换热能力不下降的条件下进一步降低冷凝器阻力损失、提升风量。对上述风道降阻设计方案的测试结果表明，针对冷凝器风道结构和管路排布的优化可提升罐箱制冷系统能效25.0%，说明本文提出的冷凝器风道降阻设计方案能够有效提升罐箱制冷系统的能效。

Abstract

Refrigerated tank containers are currently the primary method of transporting cryogenic liquids. The air outlet of the refrigeration system is blocked by the liquid tank

resulting in low energy efficiency of the refrigeration system. This study aims to improve the energy efficiency of the refrigeration system for a tank container with a limited installation space. The resistance loss of the air duct is reduced and the air volume of the condenser is increased by optimizing the condenser air duct structure and pipeline arrangement

thereby improving energy efficiency. By optimizing the structure of the air outlet

sufficient air volumetric flow rate can be achieved under blocked conditions. By optimizing the pipeline arrangement

the resistance loss of the condenser is reduced

and the air volumetric flow rate is increased. The test results of the above system show that air duct structure optimization and condenser flow path optimization can improve the energy efficiency of the refrigeration system by 25.0%

indicating that the proposed optimization scheme can effectively improve the energy efficiency of the refrigeration system for tank containers.
