[Equest-users] Modeling HVAC system with heat recovery

[John Aulbach]

 Ahmed:
When you change systems, you will definitely need a new run. And you describe the DX heat pump as self contained. I will assume this is a room size heat pump, such as a thru wall unit in a hotel.
What you would use heat recovery for (not sure the DX unit can do that) is beyond me.

 Hello,
I have a model in eQUEST that has FCU as the HVAC system with heat pump chiller for a residential building. 
Now I need to change this HVAC system to DX heat pump and this heat pump is small and self contained in which it can be installed inside the room and will have inlet and out let ducts for the condenser air to the outside (I.e. without outdoor unit). This unit will have also heat recovery option and supplementary electric resistance heater.
My question is, what is the best HVAC system in eQUEST that I can use for this heat pump and in the same time enable the heat recovery option tab and the supplementary heater option tab? And also, do I need to assign a new HVAC system for each zone or I can assign one HVAC system for a group of zones similar to the FCU system?
Thank you very much for the help.
Regards
Ahmad
