Hi Jonathan,
I guess the VRF cost is linked to the auto sizing outcome. If this is the case, what you really need is to get the sizing information from E+ output. Then you can apply multiplier (e.g. $/kW) in the jEPlus .rvx file to calculate the VRF system's cost, before adding it to the total cost (excluding VRF) reported by E+.
At present, jEPlus does not read zone and system sizing reports in the epluszsz.csv and eplusssz.csv. The only place to get sizing info is from Component Sizing Summary in the summary report (request AllSummary in Output:Table:SummaryReports, and see the resultant eplustbl.htm.) A more convenient and faster way to pick a single number of the summary report is using the CSV function rather than SQL. See documentation here: http://www.jeplus.org/wiki/doku.php?id=docs:manual_1_7_rvx#read_from_e_csv_tabular_report.
Let me know if this doesn't work. There are other ways (e.g. EMS) we can try next.
Regards,
Yi
