摘要

对水平表面在低温高湿条件下结霜过程进行实验研究

分析了冷面温度、湿空气温度和表面特性等因素对水珠冻结和霜层生长的影响。结果表明:冷面温度越低

过冷水珠冻结时间越短、冻结直径越小;在湿空气温度与冷面温度温差相等的条件下

湿空气温度越低

过冷水珠冻结时间越短、冻结直径越小;疏水表面上过冷水珠的冻结时间比裸铝表面晚。冷面温度越低

湿空气流速越快

则霜层生长越快。

Abstract

Frosting process on a horizontal plate was experimentally investigated in this paper. This study focuses on several factors affecting the condensate water droplets freezing process and frost layer growth process

i.e. the cooling surface temperature

the air temperature and humidity

and the surface type. The results showed that the condensate droplets are smaller and freeze earlier with lower cooling surface temperature and lower humid air temperature. The water droplets freezing onset time on the hydrophobic surface is about 13 min later than on the bare aluminum surface

which means the frost process on the hydrophobic was delayed. The frost layer grows faster with lower cooling surface temperature and higher air velocity.
