Warnings while simulating a walk-in freezer using Air-chiller object

edit

Hello community,

I'm currently working on simulating a walk-in freezer using the Air-chiller object, but I've come across some warnings. If anyone has any suggestions on how to get rid of them, I would greatly appreciate your help.

Thank you.
