Indirect Air side Economizer

I am simulating an HVAC system for a data center.

I want to evaluate an indirect air-side economizer to take advantage of cold temperatures and prevent unwanted pollution and humidity from the outside (unlike a direct air-side economizer).

Since my return air in the AHU is 100% recirculated, OpenStudio doesn’t allow me to add an air-to-air plate heat HX exchanger.

It only allows it when I have an outdoor air (OA) system in my air loop.

Any ideas on how to do this? image description
