Why is there humidity in the room when air conditioner is cooling? Room feels damp.
It depends on the BTU of the air coditioner, the cubic footage of space in the room to be cooled, and the temperature and humidity in the room. Under best conditions, an standard air conditioner can only cool a room to the mid 60's. Any colder than this causes the evaporator to ice over, clogging the air flow into the room, which causes the temperature to rise, even though the air conditioner is still running.
Willis Carrier invented the first air conditioner in 1902. He was trying to fix a printing machine that was continually smudging ink and realized that humidity was causing the problem. So to get rid of the humidity he invented the air conditioner. He started his Carrier air conditioning company in 1915, which today is a multi-billion dollar business.
How much space a room air conditioner can cool is dependent on the size of the unit. You can read the amount on the side of the box if you are not sure.
Because the cool air from the air conditioner is denser than the warm air in the room and sinks. Placed high up the cool air will have time to get further from the air conditioner before it settles to the floor, allowing it to cool more of the room. Placed on the floor the cool air will mostly pool around the air conditioner and very little of the room will be cooled. Some air conditioner are actually placed relatively low in a room, but they have fans and baffles that blow the cold air upwards to the ceiling resulting in the same effect as placing the air conditioner high (maybe even better as the fan blows the cool air not only up to the ceiling but across it, possibly covering a larger volume of the room than cool air falling passively from an air conditioner placed high but without fans).
Seriously? Cold air blows out of the air conditioner when it's on, reducing the temperature of the room. When the temperature in the room reaches some preset value, the air conditioner shuts off to prevent the temperature from dropping any lower. Once the air conditioner is shut off, heat sources within the room including people, appliances, and heat entering through walls and windows causes the temperature in the room to increase. When this happens the air conditioner kicks on again to bring the temperature back down. It ain't rocket science.
The simple answer is no. What an air conditioner does, is cool air (obviously). When air is cooled however, it loses its ability to hold moisture. Therefore, the relative humidity (Water vapor/Capacity) of the air in the room will increase despite the fact that no moisture was added.

A room air conditioner will being putting out a haze if the air contains high levels of humidity. The mixture of cold and warm air will produce visible water vapor.
A window air conditioning unit placed in a windowless room ceases to be an air conditioner and instead becomes a dehumidifier, however, unless the condensed humidity (water) is removed from the room, it will simply be absorbed back into the room air as humidity.
It is the humidity from the air passing through the cooling coil that has condensed on the coil. By drainig it out the humidity inside the room is reduced and you feel cooler.
If the water vapor amount stayed the same, then the relative humidity would be greater.
This is water that has condensed out of the room air on the evaporator coils of the air conditioner, and it is completely normal. If the humidity is high, one will see more water condensing and dripping from the air conditioner than when the room air is dry.
The word, 'air conditioner' is a noun. The definition of air conditioner is a machine that controls the humidity and temperature of the air.
Dry Mode is a function that will reduce the humidity in the room. In this mode, as the air passes through the air conditioner the humidity will condense on the evaporator so that the air comes out drier. Reducing the humidity makes you feel cooler and more comfortable. Dry mode uses less power than cool mode.
A battery room may not require cooling, but it will require low humidity -- and for that you may need a cooling system or air conditioner.
You can keep your windows open with the air conditioner running, but by doing so, you are letting the hot air in, the cold air out, wasting electricity, and causing your electric bill to be higher. If you want your windows open, it would be best to turn off the air conditioner. In a car, it is recommended to leave the windows open for a few minutes for the hot air to escape...then close the windows and enjoy.
A humidifer can only add water to the air in a room. An air conditioner can do a lot more than that, it can: * chill or cool the air * remove water (de-humidify) the air * add water (humidify) the air.
