Dehumidification extracts moisture from the air, lowering humidity.
Desiccants, such as calcium chloride, silica gel, and activated alumina, are substances that absorb atmospheric moisture and are integral to dehumidifiers.
Their function is to maintain dry indoor air, thereby preventing mold growth, corrosion, and moisture-related damage.
Humidification, conversely, involves increasing moisture levels.
Sensible cooling and heating modify air temperature but do not directly remove or introduce moisture through chemical means.
Consequently, these desiccants are specifically employed for dehumidification.
