Minimum number of shell units in series for shell-and-tube heat exchangers

This post was last edited by Lao Sai on 2009-12-23 21:56. When using HTRI to calculate shell-and-tube heat exchangers, how do I determine whether to use them in series, based on the temperature difference? Or based on other thermodynamic parameters? Could you share any experience you have? I am very grateful. . .
If the inlet and outlet temperatures of the hot and cold fluids intersect, then it may be necessary to use a shell-side series connection.
Is this the only reference condition for the series shell side? Or, series connection is also used when the inlet and outlet temperatures of the hot and cold fluids do not intersect.
In the past few days, I have been researching relevant materials and have gained some understanding regarding the series connection of heat exchanger shells; I have also used graphical methods in these materials to provide a clearer explanation of the number of shells connected in series\
We have built heat exchangers in series, even 5 units in series, but I’m not very familiar with the process calculations; I need to learn from those who are more experienced*
