本文以结霜机理、霜层增厚速率方程以及霜层对制治装置的影响出发,讨论了如何控制结霜的位置以缩短融霜时间的方法,介绍了减少冷库内湿空气中水份以减少结霜重量的措施,最后提出了改进蒸发器的结构方案. In this paper, the frost formation mechanism, frost layer thickening rate equation and frost layer on the impact of the treatment device, discussed how to control the location of frosting to shorten the defrost time method is introduced to reduce moisture in the cold air to Reduce frosting weight measures, and finally proposed to improve the structure of the evaporator program.
