Dehumidifiers remove excess moisture from the air to maintain a constant humidity level. A Humidifier inversely, adds water vapor into the air to increase the humidity level. There are two types of dehumidifiers, condensate dehumidifiers and desiccant dehumidifiers.
Condensate dehumidifiers removes water from the air as its temperature falls below the dewpoint temperature. Desiccant dehumidifiers attract and bond moisture with hydrophilic materials such as silica gel and is used for low humidity/ dewpoint applications.
Humidifying process applies either Adiabatic and Isothermal humidification. Vaporization is an isothermal process while atomization and evaporation are adiabatic processes.
