#1054 new bug

1-stage AC heating mode flow rate is 2x what it should be

Energy Plus error? Seen in hourly output when dividing fan flow rate by runtime fraction. Cooling flow is as expected. 2-stage flow rates are as expected.

Affects duct leakage. 36% increase in heating duct leakage when going from 1 stage SEER 16 to 2 stage SEER 16, due to much decreased runtime fractions (~50%) during heating mode.

Is this still a problem using E+ 8.6?

Still a problem using E+ 8.6. I'll prepare an EnergyPlus bug report.
