I am going to try this, and I can’t think of any reason it will not work. I built a queen sized bed in my van and have been looking for a portable air conditioner that would keep me cool when sleeping in hotter climates. Staying warm is not a problem because I have a great heater, but have been miserable a few times. I only found 2 units that interested me. One is the Zero Breeze MII and the other is the new EcoFlow Wave. Both are expensive and I had never seen any great reviews on any of them. I had an idea that I hope works!
I plan on closing off my sleeping area, which should make it so something like the Zero Breeze should work, I hope 🤞
