I suppose this counts: Although not that interesting, I have one of those AC units in my apartment that sits on the floor with an outlet tube terminating at a window to pipe out hot air. The internal reservoir for this unit is quite small so I hacked together a float valve that triggers a pump to offload the condensation water to a larger bin, that way I don't have to empty the reservoir as often.

Pretty simple, but saves lots of time and I don't have to worry about the air conditioner turning off in the middle of the night due to it's internal reservoir becoming full.

Curious why not pump it out of the window? It’s only going to be a few dribbles every few hours.

It's the little things in life.

Why not just have it drain into an ordinary condensate pump which is built for this purpose? Those roll around ACs usually have a spigot to attach a hose you can run into a drain.

You might want to add an intake tube, to cool the compressor more efficiently: https://imgur.com/gallery/kA4Z0uV
