Rating of Heat Exchangers - Procedure?

Rating of Heat Exchangers - Procedure?

Rating of Heat Exchangers - Procedure?

(OP)
Dear Eng-Tipers,

Is there somewhere a procedure, practice, standard, or guideline for the rating of heat exchangers of any kind?

TIA

RE: Rating of Heat Exchangers - Procedure?

I think you might be looking for the ARI standards. ARI 400 would be typical.

RE: Rating of Heat Exchangers - Procedure?

You can download AHRI standards at the link below

Maybe "AHRI 410-2001: Forced-Circulation Air-Cooling and Air-Heating Coils" could be of some utility (not much sure).
 

RE: Rating of Heat Exchangers - Procedure?

what kind of heat exchanger (Shell tube/ plate frame/ air cooled/ surface condenser/ cooling tower)???

RE: Rating of Heat Exchangers - Procedure?

dogtop,
(funny, what's in top of a dog??! let me guess...)
The rating of a heat exchanger is almost the same process as designing it. You need to be very good at understanding the thermal properties of the process fluis flowing through an exchanger (including the air used for coolers) and have access (and understanding) of a complex design software like HTRI. Then you'll be able to perform exchanger rating calculations (HTRI does rating calcs for TEMA exchangers, plate exchangers, air coolers, etc).
The google might be a way to go, but I suspect you have already checked out this venue and not much joy was offered. All those good advices require some engineering experience and a lot of reading in the heat transfer books.
Alternatively, if you need a quick answer, come back with a specific question, perhaps the process datasheet and you might get lucky, someone will run a short rating calculation for you. Otherwise, I can give you a list of boock, manuals, standards you can study, then you can do your own calculations.

gr2vessels,

I'd like to take you on your offer

"I can give you a list of boock(sic), manuals, standards you can study, then you can do your own calculations"  

How do I get that list?

Thanks for your kind assistance.

RE: Rating of Heat Exchangers - Procedure?

I am on vacation for the rest of the year so I can't walk over to a co-worker's cube and look to get details other than the title from my memory, but he/she has a book called "Process Heat Transfer" that he/she and I refer to regularly.  If you didn't have something like HTRI (which we also both use regularly) it would be the next best thing IMHO.

Google will get you to it.

Sorry for the typo, I'm sure you guessed it from my accent that the English is not my first language.
Also, as usually, Patricia is lending us a helping hand;- from me, here is another good link:
http://www.wlv.com/products/databook/db3/DataBookIII.pdf
Learn also the TEMA 9th edition, ASME VIII which includes the mechanical design requirements for these heat exchangers, etc..
