RE: [EnergyPlus_Support] Using EP Macro to Model Template Water to Water Heat Pump system

I think we are talking about different macro's.

The attached file shows how a 55 zne file can be reduce to that, with all the details in the .inp file.

Note that for zone sizing object, all I have is a list of zone names. The zone macro will expand that to all the zone sizing object with different names.

Typing ZoneSizing [ Zone1 ] will change the line with mmZone to Zone 1 and generate the compele listing in the epmIDF file.

=============================

##def ZoneSizing [ mmZone ]

Sizing:Zone,

mmZone, !- Zone Name

14., !- Zone Cooling Design Supply Air Temperature {C}

50., !- Zone Heating Design Supply Air Temperature {C}

0.009, !- Zone Cooling Design Supply Air Humidity Ratio {kg-H2O/kg-air}

0.004, !- Zone Heating Design Supply Air Humidity Ratio {kg-H2O/kg-air}

flow/person, !- Outdoor Air Method

0.00944, !- Outdoor Air Flow per Person {m3/s}

0.0, !- Outdoor Air Flow per Zone Floor Area {m3/s-m2}

0.0, !- Outdoor Air Flow per Zone {m3/s}

0.0, !- Zone Sizing Factor

DesignDay, !- Cooling Design Air Flow Method

0, !- Cooling Design Air Flow Rate {m3/s}

, !- Cooling Minimum Air Flow per Zone Floor Area {m3/s-m2}

, !- Cooling Minimum Air Flow {m3/s}

, !- Cooling Minimum Air Flow Fraction

DesignDay, !- Heating Design Air Flow Method

0, !- Heating Design Air Flow Rate {m3/s}

, !- Heating Maximum Air Flow per Zone Floor Area {m3/s-m2}

, !- Heating Maximum Air Flow {m3/s}

; !- Heating Maximum Air Flow Fraction

##EndDef

!- =============================

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.

Hello Mr Baharvand,

Thank you very much for replay.

I'm trying to model a Water to Water Template HVAC system with EP Macro and for me it is not the problem to understand network and node connection. The problem stands, how can be used EP Macro comand to model a Template HVAC system ?

thanks again for replay

Regards,
Dashamir

Hi,

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,

Ehsan

Example Files Link to Objects - shows the first three example files (if that many exist) that have a particular object.
From the second spreadsheet:
HeatPump:WaterToWater:EquationFit:Cooling 1 GSHPSimple-GLHE.idf
HeatPump:WaterToWater:EquationFit:Heating 1 GSHPSimple-GLHE.idf
HeatPump:WaterToWater:ParameterEstimation:Cooling 2 GSHP-GLHE.idf PlateHeatExchanger.idf
HeatPump:WaterToWater:ParameterEstimation:Heating 2 GSHP-GLHE.idf PlateHeatExchanger.idf

Hi Li,

Till now I have not get any replay.
I'm trying to understand how does that work, but nothing is explained clearly at E + plus documents (at least for me).

In attachment there is the imf file, which is not more than an example of Water to Water Heat Pump system idf file converted in imf file.

I would greatly appreciate any help, advice or discussions..

thanks in advance ...

Did you get any reply to your question?

Would you like to share your IMF file for discussion?

Hi all,

I'm trying to use EP-Macro Program to model a Template Water to Water HVAC system.
Does any body have modeled such one or symilar system with EP- Macro Program ?

thanks in advance .....
