I actually find that a fan that blows air (in my case, a Vortex fan; really good fan, too) around a room or even directly at you, in a dry heat environment inside your home can actually keep you cool. Your sweat's your best friend in that aspect. But a room with high humidity, even if it's 20 degrees cooler, would not only feel hotter, but even if air is being circulated inside that room, it won't feel any cooler because moisture would probably keep the temperature at a steady level longer.
I would assume that the lower the humidity, the less AC needs to be used to cool the air out. A refrigerator works best by taking moisture (humidity) out of the freezer and introducing cold air. As moisture can keep energy/heat for longer periods of time, it makes sense to devoid a place of moisture before introducing cold air. From my limited meteorological classwork (or class spanking), I believe the more moisture you have in the air, the more energy it would take to evaporate that moisture. Premise behind evaporative cooling dictates the energy needed to evaporate the water is absorbed from the air (heat is absorbed as energy to evaporate the water), and resulting air is cooler...
In Fresno, if heat ouside is 100 degrees, and humidity is 80%, it feels like an underwater sauna... Turning up the outside water cooler doesn't do much at all, as certain parts of the house would actually feel warmer because of the increased humidity. That's when the dehumidifyer comes in handy, and the Trane AC is used...
So to answer the question, after all this /ubbthreads/images/graemlins/rant.gif 'ing , I'd say your AC will work harder to cool down a place that is 90/80 heat/humidity, rather than a 110/40 heat/humidity...
