[BLDG-SIM] Circulation Loop Fluid Type in eQuest



All –

 

DOE2.2 documentation (see below) indicates it is possible to specify circulation loop fluid properties for fluids other than water (also, fluid heat capacity is reported in PV-A, which seems to indicate this parameter should be adjustable). The keywords in the documentation are FLUID (acceptable values WATER, ETHYLENE-GLYCOL, PROPYLENE-GLYCOL) and FLUID-CONC (%) to specify fluid type and its concentration. I don’t see any place to specify these parameters in any of the wizards or the Detailed Design mode. I tried editing the keywords into the definitions of the CHW and HW circulation loops in the input file, which generated UNKNOWN KEYWORD errors (curiously, only for the FLUID keyword, not FLUID-CONC). Does eQuest constrain the user to 100% H2O or is there some way to affect these values? Is FLUID not the right keyword (FLUID-TYPE doesn’t work)? Should the fluids be defined somewhere other than in the definition of the circulation loop?

 

Documentation can be found by entering the DOE2 help screen and selecting CIRCULATION-LOOP in the index, which provides several options to display. Select “circulation-Loop” (note non-standard capitalization) and you will get a list of subtopics to select from. Select “Brines” and from the subtopics at the bottom of the resulting screen, select “Actual Fluid”. The keywords noted above should be available from there.

 

Thanks for any insights.
