Hi,
I could be wrong but I don't think there's an option to do this right out of the box in E+ (meaning there isn't a field to add an exhaust air node at the condenser air inlet node but that's easy to check).
Otherwise you can do this with EnergyManagementSystem (EMS). The logic would likely be similar to this:
Put a sensor for temperature (and flow rate) at the exhaust air node of your airloopHVAC(s), and an actuator or the outdoor air node for the condenser inlet and overwrite its temperature via an EMS program. You'll likely need to do some calculation on the temperature if you think your exhaust airflow is lower than the condenser inlet airflow needed (in this case a sensor for the flow rate is needed too).
Hope that helps,
Julien

Hi,
How do I extract the exhaust air temperature and flow rate of an air conditioned building from an Energyplus simulation? I was thinking to reclaim some of the cooling in the exhaust air for condenser cooling. Can someone guide me on this using one from the ExampleFiles, say "5ZoneAirCooled.idf" or share me their experience.
Regards,
Tilek
