摘要

结霜现象是阻碍翅片管蒸发器在制冷系统应用的主要不利因素之一。为准确预测霜层生长特性，基于耦合VOF多相流和相变传质速率模型方法，对强制对流条件下三维翅片管表面霜层生长行为进行了数值模拟，模拟得到的霜层厚度与实验结果相比最大差异控制在15%以内，霜层密度的估计值在高达90%的置信区间内，吻合较好。通过搭建翅片管蒸发器表面结霜可视化实验平台，分析了在单因素变化下环境温度、相对湿度及迎面风速对翅片管表面霜层生长特性的影响规律，结果表明：霜层厚度随着进风气流方向从前向后逐渐降低，空气温度越低、迎面风速越大及相对湿度越高，霜层厚度、结霜量及霜层热阻也越大，相对湿度85%下的霜层厚度达到最高，为2.344 mm。根据Morris敏感度分析法得到相对湿度对霜层热阻的影响最大，敏感度系数达到2.41，并使用最小二乘回归方法得到霜层热阻关于不同环境参数下的相关性。

Abstract

Frosting is one main adverse factor hindering the application of finned tube evaporators in refrigeration systems. To accurately predict the growth characteristics of the frost layer

its growth behavior on the surface of a three-dimensional finned tube under forced convection conditions was numerically simulated based on the coupled VOF (volume of fluid) multiphase flow and phase change mass transfer rate model method. The maximum difference between the simulated frost layer thickness and the experimental results was within 15%. The estimated value of the frost layer density was within a confidence interval of up to 90%; this is in good agreement. By building a visualization experimental platform for frosting on the surface of the finned tube of the evaporator

the influences of ambient temperature

relative humidity

and frontal wind speed on frost growth characteristics under single-factor changes were analyzed. The results showed that the thickness of the frost layer gradually decreased from front to back in the direction of the airflow. The lower the air temperature

the greater the wind speed

the higher the relative humidity

the larger the thickness of the frost layer

the more frost

and the larger the thermal resistance of the frost layer. The thickness of the frost layer reached its highest value of 2.344 mm at 85% relative humidity. According to the Morris sensitivity analysis

the relative humidity had the greatest influence on the frost layer thermal resistance

and the sensitivity coefficient reached 2.41. The correlation of the frost layer thermal resistance with different environmental parameters was obtained using the least squares regression method.
