I have seen many people wanted to use 100% outside air and does not know what to do.
If your OA intake volume rate is the same as the fan capacity and the zone air flow rate, the return air is automatically relieved, 100%.
If you do not connect the return air node of the zone to the OA mixer, the zone air is also 100% exhausted to the outside environment.
Am I right?

Subject: [EnergyPlus_Support] Air Exhaust from zones problem
hello everyone.
i'm doing my first attempts on HVAC simulation, and i've hit my first wall. The system i'm trying to simulate is working with 100% outside air, and thus i need all zone air to be exhausted outside, with no return. My first idea was to use a AirLoopHVAC:ZoneMizer object to bundle all the air from the zones, and use the Outlet Node Name defined here as the Demand Side Outlet Node Name in the AirLoopHVAC object. But it seems E+ doesnt like my ideia, i'm getting a severe error saying the node name in the AirLoopHVAC object is not valid. If someone could point me out a hint or two on how to do this, or at least reference me an example file that uses a similar system, i would be very gratefull. thank you for your time!
