Design of heat exchangers
Thread Content
For the design of a heat exchanger, the overall heat transfer coefficient K is estimated based on experience, and then the heat exchange area is calculated. Once the area is determined, what comes next?................
For the selection of heat exchangers, after making the choice it is necessary to calculate the heat transfer coefficient; having a margin of 10–20% should be sufficient. It is also important to calculate the pressure drop and other factors to ensure they meet the process requirements.
Fixed tube sheet type, floating head type, U-tube type – that’s it; anyway, you might not need the others
Estimating the heat transfer coefficient based on experience is not advisable.
These days, whenever I don’t know something, I have no choice but to search on Baidu. No one in the whole company uses this tool, and trying to figure things out on my own is really frustrating. Please add me on QQ at 286791707; I have questions I’d like to ask you directly. Really, please help me – I hope you can understand how I feel. I won’t keep asking all the time; I’ll ask when you have time. Thank you very much
Time to get up and go to work....................................
Hehe, I don’t have any software for heat exchanger selection calculations here, so I have to do the calculations by hand. . . . . :L
I do the calculations by hand too, haha. I’ve just figured out the area, but I don’t know what to do next; there are no specialized books on heat exchangers
