Computerized Simulation of Temperature and Velocity Field in Freezer

本文建立了冷冻箱箱内流动与换热的物理、数学模型，结合对制冷系统的计算模拟，编制了通用计算程序，并对一台国产冷冻箱进行了数值计算，所得结果与实验值相一致，在此基础上提出了改善箱内空气温度均匀性的措施。

This paper establishes the physical and mathematical models for the flow and heat transfer inside a freezer.A general computer programme has been developed combined with the simulation of refrigerating system.With this programme,the temperature and relocity fields of a freezer are calculated,the results and experimented ones are in good agreement.Futhermore,based on this programme a method to improve the homogeneity of air temperature in a freezer is presented.
