Re: [EnergyPlus_Support] Compatibility between air system objects

Yes, it is possible to set up an air loop (which uses AirTerminal:* 
objects) and zone equipment (e.g., PTAC and 4PipeFanCoils). See the 
example file ZoneWSHP_wDOAS for an example of an air loop used with zone 
equipment. This is a very simple example file, where there are no 
components in the air loop (but you could add them) and only a single 
piece of zone equipment (you could have more and add additional zones if 
you like). Just reconfigure the air loop as you need and choose the zone 
equipment you would want. Take note of the ZoneHVAC:EquipmentConnections 
object on how to describe multiple exhaust/inlet nodes for a single 
zone. Also, only 1 air loop (AirloopHVAC) is allowed per zone (but can 
serve multiple zones) and connects between a zone return node and a zone 
inlet node. The zone equipment (ZoneHVAC - e.g., PTAC) connects between 
a zone exhaust node and a zone inlet node.
