摘要: 建立了超市立式冷藏陈列柜食品温度变化的瞬态计算模型，利用该模型分析不同冷藏条件下传导、辐射、自然对流3种传热方式对食品温度之影响规律，结果表明：1）陈列柜各个位置的温度分布不同，靠近风幕送风口位置的温度最低，底层前排侧位置的温度最高；2）不同传热方式对食品温度影响不同，依其权重大小可排列为传导 > 辐射 > 自然对流，因此强化搁架的热传导能力，能起到较快降低食品温度的作用；3）不同位置降温时间有所不同，靠近风幕送风口位置温度下降速率最快，可放置易变质食品.利用该模型可以用来预测食品包的冷却规律，为食品最佳冷藏提供参考依据.

Abstract: The transient temperature computational model of the change of food temperature was set up. With the established model the influence rule of various heat transfer modes such as conduction, radiation and convection on the temperature of food in different storage conditions was analyzed. The results showed that the temperature distribution of each position of the display cabinet was different. The results showed that the temperature near the air curtain air supply outlet was the lowest and the temperature on the bottom of the front position was the highest. Secondly, the effects of different heat transfer modes on food temperature were different, and the weight size was conduction > radiation > convection. So strengthening the heat conduction ability of the shelf could rapidly reduce the food temperature. Thirdly, the cooling time at different locations was different, and the location near the air curtain air supply output of the fastest temperature decline could be used to place easily spoiled food. This model can be used to predict the cooling rule of food package and provide reference for the best food cold storage.
