I have been perfecting a well know method ( evaporative cooling of the intake air to the condenser) of reducing the energy needed to power home air conditioners ( this method has been used by commercial air conditioning for decades. See this -
*.mammoth-*/Innovation/E ... nsing.aspx
In actual test data we boost cooling by 30 % and reduce the energy needed by 25%
When you combine these 2 items the results are shocking
A typical 10.7 EER window unit will now dewliver an EER of 15 to 16
Using the formula for sensible cooling CFM x 1.08 X delta T F / watts we really do get into the 15 to 16 EER range at 90 F outside air temp
California has wasted 2 decades farting around with this idea for home use .
A simple throw away coolig pad once a year is all that is needed to keep a simple precooling operating.
I have been testing for 3 years in the hellish Tucson 110F summer with great results
Has anyone else tested retrofitted precoolers
