SEMINAR on DEHUMIDIFICATION
Desiccant Based
Desiccant Dehumidification - A specialisation in it's own right
To Dehumidify or Dehumidification - literally means "pulling
out or removing" the moisture/humidity from the air.
Dehumidification, unfortunately, has always been treated as
a poor cousin of the airconditioning industry.
People, know what a cooling or heating system is; they understand
airconditioning; they are even aware of humidification; however,
when it comes to dehumidification, the awareness is fairly low.
However, with increased focus on "Humidity Problem"
in the ASHRAE Standard 62.1 1999, the attended on dehumidification
has increased.
Since airconditioners are known to remove some amount of moisture,
it is often assumed that airconditioning will lower the relative
humidity in a space.
And it surprises people when the exactly opposite happens.
It is quite possible that the relative humidity actually increases
when the temperature in the room is lowered, as cold air cannot
retain the same amount of moisture as warm air can.
However, of late, dehumidification, has started to be recognised
as the increasingly important member of the HVAC family, and
as a specialisation and a science in it's own right!
The purpose of this article is to familiarise ourselves with
desiccant dehumidification and it's various aspects.

Why Dehumidify ?
"It isn't the Heat, it's HUMIDITY"
!!!
All who have suffered the discomforts of a hot, humid summer
day understand this statement and are familiar with the effects
of moisture in the air. That "muggy", uncomfortable feeling
results because the relative humidity of the surrounding air
is high. If the relative humidity were low on that same hot
summer day, our body would not feel as uncomfortable. |
