Re: [EnergyPlus_Support] Temperature out of range on a High rise with plenums
These anomalies are happening at very low load conditions in "Detailed Flat
Cooling Coil 1". If you change the Min Actuated Flow in the controller for
this coil from 0.0000001 to zero, the errors go away with a negligible change
in results.
Also, I noticed that the schedule specified for PEOPLE activity level is a
fractional schedule (0 to 1). This schedule is in W/person, so the internal
heat gain from PEOPLE is way too low.
