Does humidifier raise or lower temp?

it sure is. VV

id like to know the answer to this as well. example, say humidity is 10 percent and temp is 80, if humidity jumps to 40 percent, what would the temp be? and the other way too, if humidity was 40 and it was 80, what would the temp be if it was 10 humidity? thanks..

--edit -- i was reading online and i found that humidity tends to make it "seem" hotter or "seem" cooler, but i cant find anywhere that it can actually have an effect on temperature. i do believe it does but i just dont know what effect tho.

Im just curious because on another site saw somebody build this contration out of a fogger, cpu fan, and a small rubbermaid. They put the fogger thing inside the rubbermaid and used the fan to blow into it shooting all the fogg out another exhaust whole. They said it lowered there grow tent's temp almost ten degrees. Its true i saw the pix. I have a humidifier isnt that the same thing.

Any one ????

A humidifier raise the humidity a dehumidifier lowers the humidity. He mad a swamp cooler pretty common as the cooled water vapr lowers the air temps but will dramatically add humidity and increase chance of mold growing but it will drop temps by adding moisture in the air

I thought temps increased with humidity??! I guess not. .

can u control humidity w/ fans & air in & exh. fans

a humidifier will give off heat reguardless of the humidity level of the room. to answer the question as asked. if you have a humidifier in the room, when it's on it creates heat that it gives off. i lowered my temps in my room almost 10 degrees by taking my Humidifier/ dehumidifier out of the room and putting it in another room that connects through the ceiling. this way I can control the humidity in the room without adding another thing to heat up the room.

Adding humidity or removing it is not what effects any change. It may 'feel' cooler or hotter, does not affect temperature. The difference is, if the humidity is high your persperation doesn't evaporate, its stay on your skin, making it feel hotter. This is 5th grade sceince. VV

I was going to say the same thing. Humidity doesn't change the temp. Lowering or raising the amount of evaporated moisture in the air does not have any effect on the air temp. The more moisture a warm room has the heavier the air is with warm vapors that are the same temp as the air. That's why you run a humidifier in the winter. The cold air is dry and sucks the moisture from your skin imitating sweat and making you feel cooler. When You have a humid room the moisture actually prevents you from being able to release moisture from your skin making you feel warmer. Like stated above, the guy made a crude swamp cooler that relys on the air from the fan to evaporate some of the water droplets thus absorbing some of the heat in the air and taking it out the exhaust port he made. The guy that had to take his humidifier out of his room probably had a steam humidifier which boils the water to get in the air thus producing hot steam and raising his temps. A humidifier that uses a medium and fan is just as effective without adding heat to your room.....

I know this is an old thread but humidity does effect temps. less humid higher temps more air moister lower temps. seen it with my own eyes.

Yeah, I know it's an old thread too... but lets look into something here. How does humidity effect your heater or AC if it's on a thermostat? If you're in Nor Cali and it's the middle of winter then you have to run a heater. Now, if the humidity drops below 50% then the thermostat on the heater can misread the actual temperature and it will tell the heater to turn on and continue to run until the thermostat thinks it's the temperature that is the set point. (yes, I know thermostats can't think). Hence, you over shoot your desired temp and blow fuses because your POS heater is running all night long. Well, that happens if I don't turn the humidifier on... on? Everything runs beautifully. This applies to AC as well but just with a dehumidifier. I know this is fact because I read about it on the internet! (Some HVAC site)

Too many variables to make a blanket statement as "indubitable". Let's say your humidity runs high. Water is a "heat bank", it takes a lot of energy to alter it's temp. This is the reason a desert is so hot during the day, cold at night (little/no water in the air). Although the dehu creates some heat, that may be less than that which is stored in the water in the air, so dehu drops temp. You could have enough moisture in the air/room that your dehu(s) runs through the night, which generates enough heat to activate AC, dropping temp, while at the same time removing moisture (which harbors heat from "lights on"). This could have enumerable effects on temp/humidity.

No way to say.
