Is it possible to model a heat exchanger between 2 thermal zones?

I would like to take hot air from one thermal zone, extract a portion of its heat through a heat exchanger, and dump the cooled air into a specific second thermal zone.

I am specifically having trouble with the dumping of the cooled air into the second thermal zone. I have tried adding the thermal zone to the air loop, and have read the Input Output Reference for each Heat Exchanger Object, however it doesn't seem like you can select where the output air is dumped.

I have only used OpenStudio for a couple months so apologies if this is a simple issue.

I'm not sure if this would work for your use case but could you mimic this kind of heat exchange either using zone air mixing objects or a highly conductive shared surface?

Hi David, thanks for the quick response.

I don't believe the highly conductive shared surface would work, as I still need to keep track of and transfer that heat to the colder fluid specifically in my heat exchanger.

For zone air mixing objects, is it possible to combine them with a heat exchanger so I can mix the air as well as transfer heat from one zone to the next? Based on my limited experience I was under the impression that that wasn't possible.
