The zone normally does have its own node.  It is required, for example, in the ?SetpointManager:SingleZone:Reheat? object and also ?ZoneHVAC:EquipmentConnections?

Thank you! Richard


I knew about "System Node Wetbulb Temp". I/O reference says that "The current wet-bulb temperature at a system node in degrees C.", however, I need to know the average zone inside WBT (like we get "Zone Mean Air Temperature"). I suppose "ZONE NODE:System Node Wetbulb Temp[C](Hourly)" and "ZONE OUTLET NODE:System Node Wetbulb Temp[C](Hourly)" are results at different system nodes (junctions), which I think are different from average zone inside WBT. Am I correct? 


In general terms, an output variable which gives WBT values as measured by a Sling Psychrometer in practical will help me. 


Thank you!

You can find the output variable for your input file in the rdd file after a simulation. You can use the wild card to get all wet bulb temps for each air node or use the name of the node (e.g., zone node or any other air node).

Output:Variable,*,System Node Wetbulb Temp,hourly; !- HVAC Average [C]

Which output variable will give indoor wet-bulb-temperature?
