摘要
用实验研究低温工况下 (- 5°C以下 )变化参数对翅片管换热器霜形成率的影响 ,获得了空气入口相对湿度、空气流速以及翅片间距等参数对结霜量和空气侧压降的变化规律。
The effect of various parameters on the rate of frost formation on finned tube heat exchangers under low temperature conditions(<-5 °C)was investigated experimentally.The varied relations,such as air inlet relative humidity,airflow rate and fin span effecting the rate of frost formation and air side pressure drop have been obtained.The results may offer the experiment basis for optimizing refrigeration system.
