This is not air conditioning. Not to be the "actually" stereotype, but air condioners literally "condition" the air by removing humidity (it was actually designed for this purpose, a side effect of removing the humidity was lowering the air temperature). This is simply good ducting and natural exchange.
Good for the environment, yes! Air conditioning? No
You're completely correct, I live in an area where you'd never be trying to add humidity lol. I was also thinking in the context of why it was originally invented, which was wrong to do. I removed my comment
