Hello to all,

I am trying to represent a HVAC System in Open Studio. The system is basically composed by a VRF system and exaustion on kitchens, bathrooms and others.

Each VRF condenser has plenty evaporators and two DOAS. So the DOAS (ducted evaporator) is also conected to the VRF tree and inflates the outdoor cooled air into thermal zones with evaporators from the same VRF tree .

Any ideas on how to input this on Open Studio?

As a guess I would try to use the VRFwithDOAS measure and then, for each DOAS I would use the maximum airflow, COP (from the VRF condenser) and cooling capacity hardsized. Then, to make complete sense, I would subtract the cooling capacity of each DOAS from the condenser.

Does it make any sense?

Does anyone have a better idea.

Any suggestion would be apreciatted.
