Re: [EnergyPlus_Support] Fwd: Usage of chilled water return to supply another system
You might try creating an availability schedule from your weather file
that has 8760 entries. If outdoor WB > 57 schedule value = 1 else
schedule value = 0. Then apply this schedule as the availability
schedule for the equipment in the other HVAC system. Not sure if this
will work though.
