Humidity
control was the problem that originally stimulates the need for air
conditioning. Lack of humidity control in hot, humid climates can lead to mold
growth and other moisture-related problems. High indoor humidity can cause
health and comfort problems.
Modern
air conditioners dehumidify as they cool which can be seen on the water that
drains away, but this dehumidification is incidental to their main job of
controlling temperature, which cannot separately control both temperature and
humidity.
In
hot, humid climates the incidental dehumidification that takes place may not
always be enough to keep the indoor humidity conditions suitable. Professional
recommends roughly a 60% relative humidity maximum at 78F.) The maximum
dehumidification occurs not at the hot times of the year when the air
conditioner is running a lot but at mild times of the year when the air
conditioner runs very little.
Although
there are some leading edge air conditioning systems that offers to
independently control humidity, conventional systems may not be able to adequately
control the problem and can cause discomfort or mold problems in particular conditions.
Some modern high-end systems have enhanced dehumidification, but when the
existing system cannot amply dehumidify, it may be important to acquire a
stand-alone dehumidifier.
Lessen
the need for dehumidification:
Avoid
setting the thermostat to the “fan on” position. In this position, the fan
blows air continually whether the cooling system is running or not, and one key
impact is that a lot of the moisture the system just took out of the air is
blown back into the house before it can drain away.
Use
exhaust fans on moisture-producing activities. Cooking, bathing, washing, and identical
endeavors produce a lot of moisture inside the house. Drain that moisture
directly outdoors by a fan. Likewise, avoid drying clothes indoors except with
a clothes dryer that is drained directly outdoors.
Avoid
opening the windows or use ventilative cooling when it is too humid outside.
