RV air conditioning water misting
 

My RV air conditioning unit will not operate for very long if the temperature is over 100 deg. F.
Last year, I installed a water mister between the fan and the condenser coils. That allowed the unit to cycle on for 20 minutes and off for 10 minutes at 100+ degrees.

I've used misters in the same fashion with 5000 BTU window hangers. That lowered my electric bill and kept the grass watered a little too well.

This year, I want to add a electric valve to turn the water on and off when the unit cycles. A 120 VAC valve would be the best IMHO, but I'd settle for 12 or 24 Volts AC or DC.

Suggestions are appreciated. Part numbers would help too. :thumbup:

Just get one from a broken dishwasher or washing machine.

Nothing is 120v on there. lots of nozzles and related stuff.

Were you able to quantify the savings on the window units?

I don't remember attempting to quantifying the savings on the a/c unit. That was before they began building units that would hold water in the bottom tray to sling into the condensers.
