Yes, that's true. I'm not an engineer of any kind, but my lame user inspections of my two units (mold makes me sick so I peek in there a lot) indicates that the only thing separating the indoor recirculating parts and the outdoor bits where the outlet fan is, is a thick piece of styrofoam. I would hate to have mycotoxin creep.

Of course the box outside is exposed to all the elements, and includes channels that with the correct pitch ditches the water it accumulates. So there's no reason I guess they couldn't make some kind of misting system that repurposes the water eliminated from the indoor space. I'd pass on that model myself though, as I'm already OCD with my current units.

ETA: All that said, you still may have a million-dollar patent right there!

Haha. I see what you mean.

I'm simply imagining a small hose that does a tiny mist to simulate rain, just above the outside unit, only while it's running, and only when the outside temp is over 85F.

I think that might avoid the mold issues.

Noice! Now go collect all your money!

Haha I might try it out on my AC. I mean I could literally just spray it with my hose sprayer by hand and measure the efficiency difference I think, to test it out. Then build a little control circuit with one of those electronic water hose switch boxes and a hose to the spigot

If it works that'd be amazing. I guess the efficiency from rain is already proven. It's just a matter of if it's more cost effective for the water use vs energy savings
