A/C Condenser Evaporative Cooling Assist

Yep, it works, but only in hot dry climates when you have a relatively pure inexhaustible water source. Try that in the desert in any MH. Come on guys, you have ask yourself WHY ALL the major HVAC manufacturers DO NOT do this for their factory installations. It's all you 100 mpg carburetor, fuel additive, free energy, Banks chip tuning, tweaky guys who want to talk endlessly about these things. (with NO long term substantiated evidence)

The quality and quantity of the water is not an issue since you are not spraying water on the condenser coils. You are pulling hot ambient air over a wet pad and part of the pad moisture evaporates which cools the air before it passes over the condenser coils. The water that does not evaporate returns to the reservoir and is pumped back up to the top of the pad. You only have to replace the water that evaporates from the pad.

In the example I gave in Dallas we had 113 deg air temp one summer and the air exiting the Aspen pad to cool the condenser coils was 85 deg. That dropped the compressor high side pressure and reduced the power consumption. For a more typical TX summer 95 deg day the electrical consumption was reduced about 14%. Even better I was not losing BTU capacity as the temp went above 95.
