RE: [EnergyPlus_Support] Using EP Macro to Model Template Water to Water Heat Pump system
You may make a template into a macro format, but the template itself is not a macro. After the template is expanded, the expIDF can be converted into an IMF and many INP files. You can then use macros to joint them together again. In that format you can replace equipment and class/object directly without going back to template again.
That was the reason why I asked you what sort of macro file you had in mind. I do not have a working .IMF file, because that was done using version 3.0. The version converter does not work well with embedded macro format. I can manually up date that file.
The detailed explanation of the EPlus macro set is in the AuxiliaryPrograms.pdf under "Input macro".
It is similar to the conditional compilation of a standard computer programming.
For example in C, you may use ##include <stdio.h> to include a header file.
##define NL printf ("\n"); to insert a newline on the display.
In EPlus. .inp is a text file for lines to be included or copied into the .IDF file or .IMF file. You can use this simply cut the .IDF into sections, so that you need not worry about changing the wrong sections, and print more than you need.
If you start to use all the functionality of the macro, then you will see some like the example I gave you. One line can be expanded into an object with the unique name and data. All the common fields will be repeated.
In the zone sizing object, only the zone name is unique. Therefore I define one Zone sizing macro with a variable name to be substituted, e.g., nnZone.
.idf is the normal IDF file. .inp is the text INPUT file which may have macros or just IDF lines. Every time, you add:
##include filename.inp
Hi Dr. Li
Thank you very much for replay.
Why do you think that we are talking about different macros ?
I'm refering the EP Macro program whcich use macro commands (same with your example) to produce regular lines of E+ (at least, I understand so).
I examined your .imf file, and noted that instead of all input fields for ZoneSizing object there are only 15 macro lines (for each zone).
When you say .inf file do you refer the same example file just changing the .imf to .inp (which I tried but nothing was different) or you refer at any other file format ?
is out there any other document which explain the EP Macro function and commands more in details rather than E + documents ?
thanks in advance...

This is in the INP file. Instead of 15 of these, you only have 15 macro lines in the .imf file.
> This can be applied to the building walls, etc. as well. The X1, X2, y1,y2, z1,z2 macro names are extered in the macro definition in the correct order with the given six number as the two diagonal vertices.
> A line, say, MExternalWall [ 0, 0, 0, 15,0,3 ] can be expanded to a full wall object on the x-axis 15m long 3m high, with one corner at the origin. The rules of entry is hidden in the macro itself. All you need to remember is always the lower conner and the diagonally opposite upper corner, vied from outside of the zone.

When you simulate this .imf file, you will get a .epmidf file, which can be rename to idf file. You can expand the imf using the preprossor or by running a simulation.
> You can apply this technique to a expIDF file after simulating a template file. You can switch and edit the .inp for the section need to be changed for different projects.

I looked to this problem several weekens ago. The example files below helped me a lot.
You can look to the SVG file to understand the network and connections. Good luck.
Kind regards,
