I don’t know . Let me go research it and report back to you

It’s never 100% humidity

But your claim is full of shite. The fan cools things down and significantly lowers the temperature. I’ve shown temperature readings in the past of what it produces without ice. Clearly though… yes it’s just obviously defying the fricking laws of physics in my backyard only. You come tell me jackass

Right now it’s 87° after midnight and I’m currently reading at 79° directly in front of the fan (81% humidity).

With no cooler and just the fan only mode going, it’s measuring at 86°. Negligible. It’s hot 87° air.

Tomorrow I’ll be sitting out back comfortably when the outside temps are running mid to high 90’s and heat index well over 100. It’s an enormous difference. And no, I won’t be wet.

ETA: I’m just trying to help people out on the home and garden board. Help them sit and relax comfortably in sweltering summer heat.

Not trying to debate “physics” of something you clearly don’t have a handle on. Go study thermodynamics instead and then get back to someone else… don’t message me, cause I don’t give a shite.

I just don't understand why you find the need to lie? You simply cannot get the temperature drop you're claiming. Sit in front of your wet fan if you wish, but stop misleading people. Bash me all you want, but "facts are stubborn things".

His claim is 100% accurate. Evaporative coolers require evaporation to occur for them to work. That is impacted by relative humidity. There is probably more going on with your system than you realize

The numbers you are showing are physically impossible to achieve through only evaporative cooling. At 81% humidity, you would get roughly 3 degF temperature drop through evaporation of water alone. You may add a bit more drop through conduction if the air flows over surfaces colder than the surrounding area. It is also possible (maybe likely) that the system uses a venturi system as part of the intake for the fan. This would provide some cooling on its own and may produce a lower pressure in the water tank area thereby allowing for more evaporation.

So either you are reporting the numbers incorrectly or there is more going on than you are aware of or telling us.

A fan does not cool anything lower than the air it is blowing. The reason we feel cooler with a fan blowing over us is due to the air typically being cooler than 98.6, our body temp, so heat is removed through conduction. Again, this makes me think there is more than evaporative cooling going on.

Kind of read like you were but
