Dehumidifier
Dehumidifier
A Dehumidifier (/diːhjuːˈmɪdɪfaɪər/) is an electrical appliance that reduces and maintains the level of humidity in the air, usually for health or comfort reasons, or to eliminate musty odor and to prevent the growth of mildew.
Etymology
The term "Dehumidifier" is derived from the Latin words 'de-' meaning 'remove' and 'humidus' meaning 'moist'. It was first used in the early 20th century.
Function
A Dehumidifier works by drawing moist air over a refrigerated coil with a fan. The cold coil of the dehumidifier condenses the moisture in the air into water, which is then collected in a removable water tank. The dehumidified air is then re-heated by the dehumidifier and expelled back into the room.
Types
There are two main types of dehumidifiers - Portable Dehumidifiers and Whole-House Dehumidifiers. Portable dehumidifiers can be moved from room to room while whole-house dehumidifiers are usually attached to your home’s HVAC system.
