At present,in the study of the frost conductivity,the structure of frost is considered as symmetrical.In fact,the conductivity of frost not only depends on its density,but is also affected by its structure.In this paper,the structure of frost crystal was analyzed,and a model of frost growth was presented.This process was simulated by computer.Based on this structure,the equation of energy balance was given for every node,and the conductivity of frost was obtained.The result indicated that this method more truly reflected the process of crystal growth,and the conductivity also agreed with the characteristics of frost at different stages.
