RESULTS Of The Condensor Misting Experiment

Thermostat set at 78 degrees. 2,200 sq. ft. under A/C.

July 2) NO MISTING: Official High 106. KWH used = 56.

July 3) MISTING ON: Official High 103 KWH used = 42.
Mister on 10AM to 10PM

Basic lighting load estimated at 10 KWH per day. Reduction
in A/C usage is 46KWH to 32KWH or 30%. Data suggests
a savings of about 420 KWH per month or (here at 10 cents
a KWH) about $42 per month.

Experiment needs confirmation in other parts of the country
(Happy Birthday today). How about Yuma? Anyone else?

106 is higher then 103.... so some of your savings are because of the lower temperature, and because you actually used water instead of electricity. A regular house is a very bad place to run this type of experiment. Temperature is importnat, but so is humididy, so is the number of times the doors have been opened, for how long they've been opened and so. Realistically, the only way to "prove" something like this is to run a "closed house" experiment, where conditions are identical. If I remember correctly, the point was to keep the outside condenser "misted". It does make sense that if the condensor is cooler, then the AC will function better. They do this all the time with power transformers and large load units. But in most cases it makes no sense, especially since in most areas hot days are "Don't use and unnecessary water" days also. Plus, there are places in which water is not cheap.....
