Air Loop
Simulation Environment Variables[LINK]
To facilitate comparing the runtime performance of various
solution techniques for the air loop simulation a mechanism to
track runtime statistics has been implemented in EnergyPlus.
To facilitate debugging the air loop simulation a tracing
mechanism operating either at the air loop-level or at the
controller-level has been implemented in EnergyPlus. To use,
one uses the “Set” command and the value as indicated.
Setting to “yes” will cause EnergyPlus to track the
performance of the air loop simulation at runtime and dump the
results in a file named “statistics.HVACControllers.csv” upon
ending the simulation. (Uses logical variable
TrackAirLoopEnvFlag in module
DataSystemVariables).
Set TRACK_AIRLOOP = yes
TRACE_AIRLOOP:
Air loop simulation tracer[LINK]
Setting to “yes” will cause EnergyPlus to write to a trace
file named “controller.<Air Loop Name>.csv” the
converged solutions of all controllers defined on each air
loop, at each HVAC iteration. (Uses logical variable
TraceAirLoopEnvFlag in module
DataSystemVariables).
Set TRACE_AIRLOOP = yes
TRACE_HVACCONTROLLER:
Individual HVAC controller tracer[LINK]
Setting to “yes” will cause EnergyPlus to write to a trace
file named “controller.<Controller Name>.csv” a detailed
description of each controller iteration at each HVAC
iteration. (Uses logical variable
TraceControllerEnvFlag in module
DataSystemVariables).
Set TRACE_HVACCONTROLLER = yes
