"화공공정에서 -35℃ 냉수는 무엇을 의미하는가",
Reply #22020-10-20
"신手上疑问,举个例子:在化工工艺中设备管道标识 -35℃冷水。我看实际温度表显示 -225℃(温度仪表是正常的的,实际温度也是 -225℃),那为什么还标识 -35℃冷水?向老工人请教直接告诉我一直就是这么叫。请问哪位大侠指点迷津",

"应该是工艺用的冷冻盐水,或低温冷冻液。楼主最好把该管道中的介质和在工艺过程中所起的作用一同描述出来。",

"本帖最后由 小鑫_ZVYY 于 222-11-22 11:28 编辑 我看到标识就是冷冻盐水的 -35℃,实际是冷冻盐水,实际就是 -225℃。那也可能是按照冷冻机工作介质 -35℃命名的标识。",

楼上的倒真是位高手,你看看以前他分析的一些问题。至于为什么叫-35度冷冻水,估计是设计温度是-35度,也就是能达到的最低温度水平。
