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。实验结果可以为制冷系统的优化提供依据
The influence of parameters of frost formation rate of finned tube heat exchanger under low temperature conditions (below-5 ° C) was studied experimentally. Parameters such as air inlet relative humidity, air velocity and fin spacing were obtained for frost amount and air Side pressure drop changes. The experimental results can provide the basis for the optimization of refrigeration system
