摘要

为研究换热器受限流道内沿程湿空气参数和壁温同时变化对霜层生长的影响，搭建了竖直布局的可视化结霜实验台。实验研究了受限流道内沿程霜层厚度、壁温、霜层生长率等参数的变化规律，以及逆流工况下入口湿空气温度、相对湿度、空气流速对受限流道内圆管表面的结霜量和平均霜层密度的影响。实验结果表明：沿制冷剂流动方向，制冷剂入口段霜层逐渐变薄，中间段霜层厚度趋于平坦，出口段霜层厚度上升。因受限效应的影响，在结霜初期流道内的霜层生长率逐渐降低；在结霜中期流道内水蒸气浓度随时间升高，可使霜层生长率出现小幅提升；在结霜后期霜层生长率降低。在壁温越低、水蒸气浓度越高的位置，霜层生长率出现局部增大的时间越早。更高的入口湿空气温度、相对湿度、空气流速会提升结霜量，而平均霜层密度随入口相对湿度升高而下降。
