机械冷板冷藏车冷板放冷过程分析研究

Numerically Calculation on Discharging Period of Hold-over Plate of Hold-over Plate Refrigerated Vehicles

机械冷板冷藏车冷板的放冷情况决定了车内货物存放的时间,而放冷过程受到多种因素的影响,从而造成冷板放冷不均匀的现象。本文建立了冷板放冷的数学模型,采用显热容法对冷板放冷的过程进行了分析,研究表明冷板放冷不充分,并对冷板的设计与优化提出了若干可行方案。

The discharging period that the hold - over plate of hold - over plate refrigerated vehicles was the key to guarantee the goods quantity, but the discharging of hold - over plate was affected by many factors, and it caused the phenomenon that the discharging asymmetry. The models of discharging of hold - over plate refrigerated vehicles were presented in this paper.The method of sensible heat capacity was used to analyze the process of discharging. It pointed out that the discharging of the hold - over plate was insufficiency. And the scherhes were discussed to solve the phenomenon of discharging asymmetry during the period of discharging.
