How Do Air Conditioners Remove Humidity?
Posted on: October 13, 2013
As summer approaches, our thoughts turn to how we can cope with the rising temperature and the humidity that often comes with it. When people discuss how they cope with the effects of weather when it gets warmer, you often hear the expression, "It's not the heat, but the humidity." This refers to the fact that while people typically can stay fairly comfortable on hot days when it remains dry, their discomfort increases with higher humidity.
Fortunately for us, modern technology provides us with a convenient method to reduce humidity-the air conditioner. Anyone who lives in an area that is prone to high temperatures and muggy weather knows that relief is imminent when you have a properly functioning air conditioning system to ease the problem. Being able to reduce the humidity makes families more comfortable in their homes.
How Your HVAC System Works to Lower Humidity
Most modern AC systems are capable of regulating humidity. Your HVAC System has an evaporator coil that condenses water vapor from the air, in a process that you may have seen when condensation appears on the outside of a glass containing a cold beverage.
This process occurs when hot, moist air in your home comes in contact with the cold evaporator coil. The liquid is then condensed out of the air, making your home less humid. The moisture collected by the evaporator coil goes to a drain and then it is sent outside, away from your home or office building.
Your air conditioner will be effective at controlling humidity only if it is correctly sized for the amount of work it needs to do. For example, a window unit that's designed for a small room such as a home office will not function properly in a large master bedroom or great room.
A central air conditioning system needs to have sufficient power to move cooled air throughout your space. Your professional air conditioning comfort specialist will calculate the appropriate size needed for your HVAC system based on the size of your home and what climate zone you live in. Your air conditioner should not be too small or too big. If the HVAC system is too large, it will tend to short cycle, with the compressor not running for a duration sufficient to dehumidify the entire building. Conversely, if your HVAC system is too small, it may not be powerful enough to keep your house at a comfortable temperature during the extreme summer and winter months.
Benefit of Reducing Humidity
The reason people feel so uncomfortable when humidity levels rise is because our bodies cool off by perspiring. When your location is humid, the air has more moisture in it, making it more difficult for our sweat to evaporate.
With lower temperatures, the air grows less humid and more receptive to the evaporation of our perspiration. The result is that you feel more comfortable.
