看叙述可知热物流走壳程、冷物流走管程。卧式改立式,需要重新设计计算,冷热物流的进出口位置、设备直径等都会发生变化。

卧式改立式,换热器需要重新计算。你们老师为什么要改为立式?一般情况下,卧式冷凝比立式效果好。

各种形式都可以,具体情况具体分析.这个变更就是推倒重来的意思了,重新设计重新算吧!

工艺理清啦就好办啦,谢谢分享

我曾经把一台立式换热器改成卧式换热器。用户使用对比后,卧式比立式的工艺效果好,

老师说立式的难设计,显得很有水平😌😌😌

大佬,那其他部分的计算公式需要变化吗?本人小白一枚

现在很多老师也不靠谱,完全没有工程概念,全凭感觉和想象。这种意见不用理他。

请大神们指导,1、卧式的改立式的,换热面积不变,相变也不变,换热效果为什么会改变?2、卧式、立式在技术设计上怎么加以选择?谢谢了!

设计推到了重来。0.6m,6m高。。。。。。。。。

通常情况下冷凝器采用卧式较为普遍,但是改成立式冷凝器也不是不可以。立式冷凝器也有其优点,冷却水沿管内壁呈膜状留下,冷策传热系数很高,如果是冷凝传热系数高而结垢倾向低的物料,采用立式冷凝器的效果不比卧式冷凝器差
