Try to define “humidification”, “humidifying”, “humidifier”, “humidity” in your own words. Do any of them have the same meaning?
What is Humidification?
Humidification is the artificial regulation of humidity in home environments, industrial environments, and health care applications such as artificial respiration. To be comfortable, people require a certain amount of ambient humidity -- not too high, and not too low. Adequate humidification in a manufacturing environment stabilizes moisture in wood, paper, and textiles, while preventing warping in glue joints. In all environments, humidification reduces fire risk and static electricity while making the area feel comfortable.
Areas in which delicate components such as electronics are assembled require precisely tuned humidity levels. Humidification is achieved using liquid atomizers which distribute moisture to the area, coupled with accurate sensors which measure ambient humidity.
In humidification, two quantities are commonly used. Absolute humidification is expressed in grams of moisture per cubic volume of air, while the more commonly used relative humidification is expressed as a ratio between the amount of moisture currently in the air and the maximum moisture the air could hold before condensation occurs. A typical comfortable level of relative humidification is between 35% and 50%. Excess humidity can cause the growth of mold or fungus. Too little humidity can cause static discharge or the accumulation of unwanted dust, contributing to allergies.
Many humidifiers are cheap and require little maintenance. In industrial settings, they are often hung from the ceiling among duct work. Humidification is intimately tied to heating and cooling systems. The level of humidity in the air is also a function of the temperature. Therefore, humidity control systems are often integrated with cooling systems.
Humidification systems are designed by mechanical engineers and are also linked to ventilation systems. Given adequate ventilation from the outside, the humidity of an indoor environment will tend to reach equilibrium with the humidity outside. Humidification is also used to "relax" old documents that have become wrinkled with age.
