摘要

针对现有对冷库空气幕湿度场数值模拟及热湿阻隔性能研究不足的问题，以某冷库水平双层空气幕为研究对象，搭建了空气幕热湿传递参数实验测量系统，建立可表征流动与负荷特性的热湿传递数值模型。经实验验证，模型模拟计算得到的测点温度、湿度与风速平均相对误差分别为2.86%、1.86%和11.40%。利用该模型，对空气幕出风角度、风口尺寸及风口位置等关键结构参数进行了改进设计，显著提升了其热湿阻隔效率。分析了不同工作模式、人员通行及货物堆放对于库内温、湿度分布及空气幕阻隔性能的影响。结果表明：结构改进后，库内平均温度、相对湿度分别下降0.4℃和0.6%，热湿阻隔效率提升9.7%；单层冷空气幕的热湿阻隔效率较单层热空气幕提高15.4%；双层空气幕协同工作时阻隔性能优于单层空气幕，且逆流出风模式较顺流出风模式的阻隔效率高出7.9%；人员通行对空气幕性能的影响具有位置依赖性，即使在影响最显著的工况下，总热负荷仍较无空气幕基准工况降低41.3%；空气幕阻隔性能随货物堆放量增加而逐渐衰减，多堆放工况下总阻隔效率较少堆放工况下降21%。研究结果可为冷库空气幕的数值分析、结构设计与运行调控提供参考。

Abstract

In response to the limited numerical simulations on the humidity field and the restricted studies on heat-moisture barrier performance of air curtains in cold storage，a horizontal doublelayer air curtain in a cold storage facility was studied in this paper.An experimental measurement system for heat and moisture transfer parameters of the air curtain was developed，and a numerical model for heat and moisture transfer capable of characterizing flow and load characteristics was established.The model was validated against experimental data，yielding average relative errors of 2.86%（temperature），1.86%（relative humidity），and 11.4%（air velocity）at the measuring points.Based on this model，key structural parameters of the air curtain，including the air outlet angle，outlet size，and outlet position，were optimized，leading to a significant improvement in heat-moisture barrier efficiency.The effects of different operating modes，personnel passage，and goods stacking on the internal temperature-humidity distribution and barrier performance of the air curtain were analyzed.The results suggest that after structural optimization，the average temperature and relative humidity inside the cold storage are reduced by 0.4℃ and 0.6%，respectively，while the heat-moisture barrier efficiency is increased by 9.7%.The heat-moisture barrier efficiency of a single-layer cold air curtain is 15.4% higher than that of a single-layer hot air curtain.The barrier performance of the double-layer configuration is superior to that of the single-layer one，with the counter-flow mode achieving a 7.9% higher efficiency than the co-flow mode.Although the impact of personnel passage is position-dependent，the total heat load remains 41.3% lower than the baseline case without an air curtain even under the most significant impact.Furthermore，a gradual attenuation in the barrier performance of the air curtain is observed as the stacking density of goods rises，with the total barrier efficiency under high-stacking conditions dropping by 21% compared to that under low-stacking conditions.These findings serve as a reference for the numerical analysis，structural design，and operational control of air curtains in cold storage.
