立式敞开式低温陈列柜柜内温度特性的实验研究

The Experimental Investigations on the Temperature Performance of Vertical Open Low Temperature Display Case

本文通过实验测试揭示了立式敞开式低温陈列柜风幕送回风温度的变化特性和货架各层温度的分布规律。实验表明风幕送风温度存在严重的周期性振荡,由此引起货架各层温度也出现周期性波动,同时货架各层温度表现不一,在垂直方向各层温度差别较大。

In this paper,the variety characteristic of supply and the return temperatures and the temperatures distribution law of load shelves in a vertical open low temperature display case are displayed The experiment shows that the supply velocity of air curtain periodically vibrate seriously which causes the temperatures of load selves periodically fluctuate The experiment also shows that the temperatures of load shelves differ vertically
