That is a commercial system that increases the efficiency of A/C systems by using evaporative cooling by means of water misting the intake air.


Here is an educated discussion on the matter:

The main concearn is rusting the coils and getting mineral deposits.

The key point seems to be having the spray as far away from the condenser as possible.

Shouldn’t automotive systems be more resilient ot road grime and debris gathering on the condenser.
I tried a homemade version of that on my car's AC using a pump up sprayer and some hose. I didn't check the pressures or temperatures (I will retest that soon and report back), but the AC did seem to perform a little better when idling in traffic. That is until I ran out of water.

I didn't use it for long enough to damage the condenser, but it might have if I used it for longer. A car's AC condenser is (to the best of my knowledge) no less susceptible to mineral buildup than a house AC unit's condenser. This problem could be eliminated by using distilled water, but that would get expensive if you have to buy the water.

However, you could use the condensate from your home AC system as a source of free distilled water. I installed a mini split in my living room but I have been too lazy to run a drain line, so it's draining into a trash can. I use that water for radiator water, in my water cooled computer, and to wash the car.
