<p class=MsoNormal>My suggestion for major hvac changes is to save a new copy
of the model by using the save as feature. Then in the new file set up
the new hvac system in the wizard mode. Finally, open up both of the .inp
files in notepad and copy in the chillers and boilers from the “wizard”
file into the existing file. Just make sure you don’t copy over the
input for the zones. This gets tricky at times, because you need to know
what actually needs to be copied over from the “wizard” file.
You will get errors opening the adjusted existing file if you copy either too
much or too little. I would suggest copying everything that you think
needs to copied and then make sure that every U-name that is referenced
(equipment names, schedules, loops, etc.) is now in the adjusted existing .inp
file.<o:p></o:p></p>
