提出了霜层综合导热系数概念。认为霜层导热系数除了应考虑霜层结构复杂性还应计及蒸汽凝华潜热释放的影响。从霜层能量平衡分析出发，导出霜层综合导热系数是霜层有效导热系数和蒸汽有效导热系数之和。据此计算的霜层综合导热系数与实验数据符合较好。
The concept of comprehensive thermal conductivity of frost layer is proposed. It is considered that the frost thermal conductivity should consider the influence of latent heat of steam condensate besides the complexity of frost structure. Based on the energy balance analysis of the frost layer, the integrated thermal conductivity of the frost layer is derived as the sum of the effective thermal conductivity of the frost layer and the effective thermal conductivity of the steam. The calculated frost layer thermal conductivity is in good agreement with the experimental data.
