Okay, so I have been studying up on solar
powered cooling options and a/c's just use too much power...so I have been looking at evaporative cooler designs both manufactured versions for retail sale as well as many diy projects...they all basically are the same principal, a water tank pumping water down a cooling pad with a fan circulating air over the pad being cooled by evaporation...
I am looking to improve upon this concept and here are my thoughts and observations...
First, these work well in dry climates like Arizona, but not so well in humid areas like here in Georgia...so why not dry the air being cooled first or heat the water before pumping it to the cooling pad? Or even better yet why not both? Logic tells me warm water will evaporate faster, and drier air will cool faster with the evaporation process...so, obviously, I don't want to use batter power to dry the air or heat the water as this will tax the battery
system...but what about building in a solar
box onto the evaporative cooler with cooper coils for water to pass through and warm up before trickling down the cooling pad? And on top of that air flow could pass through the same solar
box to dry the air as well before being passed over the cooling pad?
Second, all the evaporative coolers use outside air cooled and pumped inside...what if, instead of using the outside air, you circulated inside air back to the evaporative cooler through a return to the solar box to get a truer and constant lowering of inside ambient temperature?
Third, what if you added a thermostat and logic boards to the equation to speed up or slow down the air flow and/or water flow depending on the temperature of the circulating air, the humidity in the air, and the effects of the solar water warmer/air dryer box?
It just seems to me there should be a way to build a more elaborate evaporative cooler that can perform more like an air conditioner using a fraction of the power consumption used by a/c....maybe even a hybrid unit combining both the evaporative cooler and an a/c unit? Use the cooler and cycle the a/c unit on less frequently but enough to really provide good cooling?
Anyone got any thoughts to my ideas?
