So, I saw a YouTube video a while back (I believe it was yours) talking about how terrible portable air conditioners are and just how much heat they radiate back into your living space.
Anyways, the apartment complex we live in is now offering portable air conditioners for rent, and has banned window air conditioners, and of course mini split units are not available. So they're the only ones available. And they make us pay for power, of course.
So for those of us who have been barred from a sensible and power efficient option: any chance you could do an experiment and tell us how to make those less horrible? Stick it in an insulated box and vent that box outside through a fan, perhaps?
Not only would I watch the video, I would copy your design and use it.
Thanks for your time & consideration.
