On the design calculations for heat exchangers
Thread Content
I’ve looked up some information on plate-fin heat exchangers and found that the calculations are quite complex. Is it really necessary to carry out such complicated calculations in practical engineering applications as well? There are also issues related to air coolers – things like air flow rate, pressure, and pump power – and I don’t know how to determine these values, as I’m new to this topic and still don’t understand many things
I need help!!!!!!!!!!!!!!!!!!!!!!!!!!:L:L:L
You can read more about relevant standards and books; I guess not many people really understand them.
I specifically found a book on plate-fin heat exchangers to read, but it’s too technical and confusing; I don’t know what criteria are used for selecting such devices in actual engineering projects{:3_46:}
The calculations are very complex, and it is difficult to carry them out manually. Plate-fin heat exchangers are usually designed and supplied by manufacturers, who have the necessary software for this purpose.
Oh my God. . . The manager asked me to write out the design methods and calculation steps for this heat exchanger; is this some kind of joke for me? {:3_66:}
If you’re only asked to write out the methods and how to perform the calculations, then just write according to what’s in the literature. But if a step-by-step calculation process is required, things get tough – such calculations usually involve iterative loops and cannot be done through simple manual calculations. See what he really wants.
He told me to write it without giving any data at all. Should I use ABCD as substitutes? I read over a hundred pages in books on design calculations – it’s amazing {:3_62:}
It’s simple then: if there’s no data, you’re just meant to find relevant information. Just simplify it and write it down; you can’t possibly give him the whole book.
I’ll take a look first; I’m busy again tonight
After reading it, I couldn’t help but ask: How is things progressing now?
