re: Set your AC to 78 degrees during the day, 82 at night, federal program suggests

That’s a lot of words to say “I don’t want to admit I was wrong.”

And in the process the dry air removes some of the water and introduces it into the space.

Yes, this is the obvious downside of swamp coolers. That doesn’t mean that the humidity makes it feel cooler. Increased humidity is a bug, not a feature.

Evaporative cooling increases indoor humidity by 5-10% of outdoor humidity...without the indcreased humidity you are merely using a fan to suck warm, dry air into the house

---

Evaporative cooling uses heat of evaporation to literally reduce the air temperature. It feels cooler because it is cooler. The humidity being stuck in the air after evaporation is simply a negative side effect. Yes, the cool air might have +10% humidity but that’s not why it feels better. It feels better because it cooled off by 10 degrees. It would feel even better if you could keep it at that temperature without the added humidity.

You know they make evaporative coolers that automatically remove the cooling medium so that it doesn’t get dispersed into the air, right? They’re called air conditioners.

the effect of sweat evaporating from the skin will cool the body but the immediate air at the surface of the skin is higher in humidity than that of the air being blown across it in at the time....

You’re making his point for him. Sweat can evaporate from your skin precisely because the bulk air has lower humidity than the boundary layer at the surface of your skin. If the bulk air has higher humidity than the surface of your skin, sweat can’t evaporate.

The poster you replied to is correct. At a given air temperature, lower humidity feels cooler. The only caveat to this is the inverse scenario when the air is actually cold. In that case humidity does make air feel colder because your body is trying to retain heat rather than give it off by evaporation. Since humid air has more specific heat capacity, it reduces the temperature of the boundary layer and makes you colder.

You are not the boss of me mfer

The savings on the AC would be offset by having to wash all the bedding every day due to the 3 pounds of sweat that would be in them.

70-72 during day maybe but that mfer is going to 68 not 78 at night

3 pounds of sweat

Ewwww, what are you, 300 pounds? Cheese come with that sweat?

I am going in the 70's at night and the 90's in the day for the next ten days. The people suggesting these temps are doing 50's and 70's where they live, and pontificate, from.

I will make my house hot like they want when they can prove to me that they are putting their heater on 42 and 52 during the winter, when I am 58 and 77 outside and they are freezing balls off.

While at the same time we just had a day where natural gas traded at negative dollars because we have so much.

People will just run generator at night if they try this bullshite.

No they won’t run a generator when gas is 30 dollars a gallon.

would be much easier if y'all weren't largely such a fat and sweaty peoples. even then, why the hell isn't the day time temp higher than night? there is probably a comfortable medium between the frigid summer AC settings you find in the south and keeping it between 78 and 82. how about round about 70ish full time

I would like proof that the idiot that thought of this, actually does that first.
