Quick Summary

A dehumidifier is a device or substance used to remove moisture from the air. This process is a key component of air-conditioning systems, which aim to control temperature, humidity, air purity, and motion within an enclosed space. Early methods of cooling air involved evaporation, while modern systems, pioneered by Willis Carrier, utilize condensation. Cooled air reaches its saturation point, causing moisture to condense and be removed. Dehumidifiers can also be employed separately or as part of a larger HVAC (heating, ventilation, and air-conditioning) system to maintain desired humidity levels for comfort and to protect products or equipment.123

…in uncomfortably humid rooms, the dehumidifier was developed, using air-conditioning technology: room air is propelled by fan across a cooling coil on which moisture condenses and then drops into a container; the dried air is then warmed and circulated. Conversely, air whose relative humidity is too low for comfort can…
