OT Which direction is your ceiling fan SUPPOSED to run?

Perhaps it depends upon the climate. I've lived in tropical climates most of my life. I've used ceiling fans for decades, long before they were popular or even commonly available. At the same time, central air conditioning in homes was very uncommon; even room air conditoners. My fans ran down, May through October (the other months were cool enough so that they weren't needed).

We now have central air but it is rarely used . It is rarely used because we like open windows and don't often need it. Why don't we need it? BECAUSE THE FANS RUN DOWN.

There's your answer as to why blowing down doesn't cool you. Nobody sweats in Arizona...no sweat, no evaporation.

Somebody slept through science class.

Now you understand why I discount 'experts'

I do not know where the code is located but it is my understanding that in AZ it is AGAINST the law in every municipality around these desert communities to paint WHITE, too blinding, just not allowed. Instead, there are a series of slightly darker/offwhite, desert colors, many named for the city of origin trying to obtain some semblance of uniformity, each contiaininng their own city name.

Yes direct sunlight onto a surface is reflected or absorbed, but walls are not direct sunlight, if done properly. They're under eaves in mid day. I even found that our garage interior at mid day was noticeably cooler with the darker color than it was before. I assume radiation of heat OUTWARDS became more dominant a heat transfer. What made me think of it was thinking about how frost used to form on lawns at 38F degrees, night sky radiation sucked the heat right out, In regions of Sahara many desert populations wear a preference of dark clothing too. so thought I'd give it a try. Now, during the transitional seasons, when neither run AIR nor HEAT; the temperature range has narrowed to around 3 degrees, which is very reasonable, before it varied 5-6 degrees. Wake up house cool, during day heats to some temp, with the narrower range we don't even turn on the Heat Pump System, irritating our utilities suppliers to no end, but saving the US overall energy costs.

I took him to mean "Nobody sweats in Arizona..." a bit more tongue in cheek, because we're allowed to carry in this state.

It is my understanding that according to scripture the purpose of the sky, and its complexity, is a way for God to talk to His people, to those who can read His messages. Not meant for everyone, but makes sense. Certainly explains why earth is located where it is. ;)

If the AC is oversized it is not efficient at removing humidity because it doesn't run long enough. ANd if it isn't warm enough to require running the AC, you still have the humidity.

Running the heater and the A/C at the same time MIGHT help, by forcing the AC to run more, but it most certainly is NOT efficient. At the price of electricity in Ontario, particularly during peak periods, it doesn't make any sense at all. We run the AC off-peak to drop the temperature and keep the house closed up on-peak to keep the heat out. As soon as it cools down outside the wife wants to open the windows - even when the humidity is 81%+ outside and only 40% inside.

Slowly getting her trained, after 33 years.

Well, our house is pretty well shaded by the tree canopy in the summer - so the absorption heat gain is not terribly high - and it generally isn't hot enough that the colour of out roof would be an appreciable factor in radiating heat over-night, but if /when it gets really Mugglyhot the darker roof is likely an advantage. Often the Mugglyhot days co-incide with significant cloudcover around here too. (Mugglyhot = Muggy/Ugly/Hot weather from hell -used to only get a couple weeks of it, split up into short periods of a couple days - lately we've been gettin 2 week stretches several times per summer.)

OR simply run the fan blowing down to "suck" the hot air down from the ceiling. That's what we did in the shop at the dealership - ran the fans 24 hours a day during the winter - and it kept the floors dry, the shop comfortable, the gas bill down, and the doors ice-free. Heat was by natural gas "unit heaters" in the top corners of the one shop, and the middle/side of the other.

Those fans paid for themselves the first week we installed them!!!!

Unlikely, unless you are 130 years old. In restaurants or even some upscale southern homes they had such fans back then. Often multiple units driven by a common motor and belts. They had less than the usual five blades of modern versions but they sure were ceiling fans.

Even today's style showed up in the stores over 100 years ago:

Ours doesn't look much different except that it has five blades.

Our AC is a heat pump which does not remove the moisture from the air -- it just cools it. Don't ask me how -- for all I know they have the thing arranged to do it on purpose.

Back in the late 1950's my father was the plant engineer in a printing plant. Humidity control was more important than temperature for comfort. They had a huge AC system and if the humidity got too high they fired up the boilers and added heat. That kept the AC running and removing moisture.

Does it make sense for you? Depends on your price of comfort. There are still people that hate the heat yet won't pay to run the AC.

Once the air gets mixing, it makes little difference. Down usually lets you feel the breeze more for some evaporative cooling that you don't want in the winter. Up is a little more gentle.

The fan eliminates stratification, but in your vase it was detrimental because the cooler air is where you were but in mixed in the hot air above. You probably wanted to exhaust the air from the ceiling, bur just mixed it.

Any heat pump or other air conditioner WILL remove humidity from the air - warm humid air passes over cool surface, humidity condenses out. Cannot be done any other way.

In industry it is the "cost of doing business".

Water does not dribble out of it, and even when it is going the dehumidifier will remove gallons from this place in a day.

But a down-pointing fan does blow the dust off.

Your condensate drain is clogged, fix it, sheesh.

But that is exactly what you *are* doing, running that dehumidifier is the same as running the big AC unit. I guess it might be more expensive to run the heat outside rather than keep it in.... but no, the heat is always run outside by the big unit because of the thermostat.

Clearly the small unit is less efficient, small things usually are. So why not run the big unit that does a great job of removing the moisture? It is larger so will need to run much less to lower the humidity. It is also equipped to remove the water while most room dehumidifiers have a bucket you need to empty unless you have it tied into a drain.
