Re: [EnergyPlus_Support] Re: how to size component and plant
Your file works fine. Your using V2.2, did you realize V3.1 is now
available?
The sizing information is in the eio file (YourFileName.eio) not the
csv. Here's the first line of the sizing info in that file.
This information is the "autosized" value for the direct air unit named
Z29745 K19 DIRECT AIR in your file.
! <Component Sizing Information>, Component Type, Component Name, Input
Field Description, Value
Component Sizing Information, DIRECT AIR, Z29745 K19 DIRECT AIR,
Maximum Air Flow Rate [m3/s], 0.21000
So for this line above, this object sized the maximum air flow rate. The
maximum flow rate is 0.21 m3/s.
DIRECT AIR,
Z29745 K19 Direct Air, !- Direct Air Name
System Availability Schedule, !- Schedule name for on/off schedule
Z29745 K19 Inlet Node, !- Zone Supply Air Node Name
autosize; !- Maximum air flow rate {m3/s}
