For the most part, it is relative humidity that people complain
about: the ratio of water vapor in the air to the fixed amount of
water vapor that air can hold for a certain temperature. For example,
at 68 degrees Fahrenheit, one cubic meter of air can retain about 18
grams of water. This is a state of saturation, with 100% relative
humidity.
How does a Dehumidifier Work?
Typically, in a dehumidifier, the process sector, which is the larger
of the two air zones, pulls system air. The rotor material present in
the equipment adsorbs moisture from the air, leaving the humidifier
warm and dry. During adsorption, the exchange of energy causes heat
gain in the equipment.
The reactivation sector, which is the other air-pulling compartment
in the humidifier, pushes out moisture adsorbed into the rotor
through the process sector. With the continuous and simultaneous
passing of opposing airflows through the rotor, steady and automatic
dehumidification is attained.
Anywhere during this process, interrupted air flow, reduced moisture
adsorption, or any other anomaly may cause malfunction of the
equipment.
What is Driving Sales of Dehumidifiers?
In cold countries, rising energy prices have been a reason for high
demand for building insulation for both commercial and residential
use. Insulation may help with the cold, but on the contrary, air
change is reduced, leading to the formation of a humidity trap. This
necessitates the use of a dehumidifier to protect the woodwork.

In construction activities, dehumidifiers have several usages. From
keeping building materials such as iron bars/rods, cement, etc. free
from moisture to drying structures, dehumidifiers help save cost and
reduce the duration of the entire project.
Thus, in Asia Pacific, economic development, leading to rising
construction activities, has been a major reason driving sales of
dehumidifiers, which in turn is benefitting the global dehumidifier
market.
On the environmental front, global warming is a major concern
attracting the attention of major governments worldwide. To counter
the ill-effects of the rising average temperature of earth, globally
accredited agencies are promoting the use of dehumidification
systems. An added bonus of advanced dehumidifiers is that they
inhibit growth of microorganisms, which is favorable for humans and
other living creatures.
Moreover, any kind of environmental disturbance, such as excessive
moisture content in the environment, also reduces agricultural
output, which directly impacts the economy of any country. For this
reason, greenhouses meant for specialty crops are essentially
equipped with dehumidification systems.
However, excessive product recalls by manufacturers due to technical
issues have adversely affected consumers’ confidence in the
dehumidifier industry. Due to the aforementioned reasons, the global
dehumidifier market will display a modest 6.4% CAGR from 2014 to
2020.
