等距离供液,即同程供液,由于制冷剂在各个环路中流经的路程相等,能在一定程度达到各个环路供液比较均匀(但不是相等)。在有相变的情况下,如果有关的管子直径(断面)选择恰当,也能起到同样的作用。但在一九八二年第二期《冷藏技术》上发表陈显冰同志写的“蒸发排管等距离供液的分析”一文,无论是在公式的推导过程,还是在等距离供液时各个环路的流量相等这一结论,都还有一些值得商榷的问题。
Equal distance liquid supply, that is, the same way for the liquid, as refrigerant flows through the various circuits in the same way, to a certain extent, to achieve a more uniform (but not equal) for each loop. In the case of a phase change, the same effect can be achieved if the relevant pipe diameter (cross-section) is chosen properly. However, in the second issue of “Refrigeration Technology” in 1982, Comrade Chen Xianbing’s article entitled “Analysis of Equal Distances for Evaporative Tubing” was published either in formulating the equation or in equidistant supply Road traffic equal to this conclusion, there are still some issues that are debatable.
