Real-World Practice - In Progress Evaluating & Calculating MEP Systems [Exercise A] Question 3 of 10Click on the area that represents the Air Handling Unit (AHU)

Hello this question is a little confusing. I need help understanding how and why an AHU is being placed in a ceiling.? The ERV handles air, the Condenser looks like it could be a RTU. Am I mistaken that the AHU would need serviced, filters changed, etc. I’ve never seen a AHU installed in the ceiling plenum before?

Thank you,
