摘　　要：探讨了冷表面结霜的过程,并综合考虑了冷表面温度、空气湿度、空气温度等因素的影响。通过质量守恒、能量守恒,采用准稳态的方法建立了冷表面的结霜过程数学模型及计算求解方法,研究了在冷表面温度、空气湿度、空气温度一定的情况下,霜层厚度、霜层热阻、霜层密度的变化曲线。提供了一种能够进行霜层生长规律和霜层物性预测的计算方法。In this paper,the process of frosting on cold surface is discussed,and the effects of cold surface temperature,air humidity and air temperature are considered.Through the conservation of mass and energy,a mathematical model of the frosting process on the cold surface and a computational solution method are established by the quasi-steady-state method,and the variation curves of frost thickness,frost thermal resistance and frost density are studied under the condition of a certain cold surface temperature,air humidity and air temperature.A computational method capable of performing frost growth law and frost physical property prediction is provided.
