A/C Condenser Evaporative Cooling Assist
I am wondering if any company offers an evaporative cooler designed to reduce RV A/C condenser inlet air temp to assist in 95+ deg temps? I designed such a system (inspired by some mechanical engineer...

I decided to not pursue the misting approach partially due to the issues you mentioned as well as mineral buildup on the condenser coils. I would however be interested in any test data you can share with/without misters vs temp.
I used 1/2" PVC coupler with brass mister, 24v irrigation valve powered via outside compressor unit, wall mounted thermostat to come on over 90F, inline calcium filter. Final config (Mr. Mister) was PVC on the ground ~12" from unit with 2 misters per 3 sides. Measured rotation of electric meter with mist was 10% longer for one revolution. Misters clogged often, 20+y/o freon unit, replaced that winter. IIRC, 10F drop in exit air temp.
Nice piece of engineering. The devil is in the details. I used the watt hour meter revolutions over 10 minutes to compare power consumed with/without cooling before committing to designing and building my home system. Your calcium filter work pretty good for you? Which one did you use?
