Air conditioning Efficiency ???

[Roland Jacques]

My Ac has been running non stop for some long durations of time lately. I was wondering if the outside Compressor coils being cooled with water a mister would lower the power usage?

It seems that a fine spay of water on a timer would allow the coils to cool faster. What would the down side be? What do you think?

Good to to hear that you have try it Shane, and your tips are good ones . Thanks.

I searched the idea and it has been marketed, and kits are available.
coolnsave & ezmister

I think it would help even new ACs. Here is a thread and some reviews from some "Green forum" they seem unanimous that it does save power and cools their houses better. http://www.greenoptions.com/forum/thread/1182/cool-n-save-to-lower-airconditioning-cost/60

im going to look at this kit closer. http://ezmister.com/index.php?page=shop.browse&category_id=6&option=com_virtuemart&Itemid=53&vmcchk=1&Itemid=53

This place has all the piece parts nozzles... and 1/2 PVC fitting to screw the nozzles into. the only thing i could not find with them is the solenoid

"This nozzle should not to be used at pressures below 250 PSI"

Have to keep an eye on that
Yeah, the orifice size determines the pressure needed. The 0.08 would not work on low pressure but the 0.14 says "0.14 nozzles are ideal for use in low pressure systems." I think the 0.12 may work also.

I found that Home depot / Lowe's sprinklers 3/4" solenoids are 24 volts.

For the solenoid, why not just get one for a garden tractor's starter?
They're 12vdc and only cost about $15.

Roland, STOP, Wait..
This place http://www.cloudtops.com/ has nozzles and recommends orifice sizes based on available pressure (I just did water injection on my truck is why I know about them) You are gonna need 8- .015" nozzles, the ones with the 10-24 thread are easy to work with. Don't use a solenoid, no use complicating the build & spending more money. The system I saw at the energy fair used an airflow lifted plastic paddle that pivoted on the stem of a valve and started the water flow when the outside units' fan kicked on, no electrickery involved. Use an inline filter, and maybe two sets of magnets exterior to the hose to charge garbage and mineral molecules one way then draw them to the next set of mags with opposite poles against the hose... Or just order one of these kits...

Thanks Gus
Their brass nozzles are the same as the Aero's that i ordered. But their colored plastic nozzles with 10-24 threads would be a better if they spray as well, Ill be trying some.

As far as the flap valve goes, i cant find any way to buy one, but to buy the whole coolnsave $90 kit.
If the plastic nozzles work and i use the solenoid valve from ho,e depot this project should have cost under $30. But since ill be experimenting ill be spend more than that.

How did your water injection work out? Do you have a thread on it?


The study papers
One subject that their study did not address was whether finer mist works better than larger mist. It seems that there could be too much, or too little water. To much could interfere with evaporating coil cooling heat flux, and to little would not allow the water to accumulate on coils before evaporating. http://www.greenwaydesigns.com/pdf/CNS_Tulane_Study.pdf
They have another study that has 4 different spray configuations wit 10% to 25% results but it does not show what they are doing differently.
