[EnergyPlus_Support] VRF and Outdoor Air

[Omar Tabuyo <omartabuyo@xxxxxxxxx>]

Dear all,

I am modeling a VRF system (just for fighting the internal load) and it use a roof-top for the outdoor ventilation air .

I know that i can introduce the Outdoor air through the OutdoorAir: mixer element. But in this case the outdoor air have been conditioned, so, Can i introduce the ventilation conditioned air in a zone, with a VRF system, trhough the OutdoorAir: mixer element?

Other simulation programs propuose to built a virtual space wihtout internal load where the energy needded for conditioning the outdoor air is taken into account.

Is it an appropiate solition in E+?

Which method would you recommend me?

Thanks
