since I live in very hot climate and humidity ( reaches 130 F and humidity 80%)where sometimes I get stuck in traffic and temperature rise up to the point where AC shut off ( happen once). I was thinking of a way which I can use the ac water-drops and extend the hose to let it drop on radiator fins.
I have an electrical fan installed front of the condenser which helps very well but just to avoid overheating,

Do you think this is a good idea?

What's the best way to let water goes forward not backward (will cause leaks under the G-compartments)?

Any thoughts, ideas of how that's done?

Advices and suggestions are welcome.
 
probably not really worth the effort as I think you would have more problems with water overflowing the evaporator box. you would need a very long hose and I thin it would go to high up to the rad to allow it to drain.

you would probably be better off adding an electric aux fan with its own switch for mor air flow over the condenser while your sitting in traffic
 
Not sure in 80+% humidity and those temps that it's going to accomplish much, the gravity/elevation difference issues (between evaporator and condenser fins) notwithstanding. You could always test at idle in your driveway and lightly mist the condenser with a hose to see what happens...

Thanks.
With humidity here, people can not breath lol so no air will be flowing much and if it did, it will dead hot and will not lower the temp.

That time when I had the ac shut off in dead traffic and very high humidity , ( coolant temp was around 217-220) I popped the hood and splash some water in condensers, and AC turned on right away. That's how I came up with this idea.

The gravity/ elevation is what worries me and that's why I asked to have it done with no overflow( water out but not in) but wouldn't the water accumulate and push its way out to the end of the hose? Specially when it's very humid, AC water drain pours tons of water?
 
First, it is the engine temp that will shut off the AC, therefore it is the radiator that needs cooling.

Second, water runs downhill, and there likely isn't enough air pressure in the HVAC system to force it out. You would need the hose running "downhill" all the way to the radiator, which by the end probably won't be high enough to do any good. The other option would be an electric pump to get the water out of the evaporator box and up to the radiator. If you really want to know how to let the water out and not back in, look up "check valve".

But really, your most cost effective solution will likely be adding additional electric fan(s) to your radiator and either have them manually switched, or somehow thermally switched.

I run a two stroke turbocharged 500hp diesel coach. It's very difficult to keep cool and I have personally installed a radiator mister to mist my radiators to cool the coolant better during uphill climbs. All this to say, you need quite a bit of water misting to provide any noticeable cooling effect. The relatively small amount of water dripping from your a/c system won't be nearly enough. Add to that the fact that this water must drain via gravity, and it just doesn't make sense. If you wanted to install a 5 gallon tank somewhere and keep that filled with freshwater and installed a misting system off of that, you might see some great results, but your condensate isn't going to cut it.
