What is a Dehumidifier?

Published 2021-04-28 in 

A dehumidifier is an electric appliance that reduces and maintains the level of humidity in the air. Dehumidifiers work in one of two ways—by refrigeration or by adsorption. A refrigerant dehumidifier works by cooling air to remove moisture using similar technology to a refrigerator or air conditioner. On the other hand, an adsorption dehumidifier works where moisture is adsorbed into a drying material and then removed.

DST has a range of desiccant adsorption dehumidifiers that are specifically designed to solve most humidity problems within the industrial and commercial sectors.

How does a dehumidifier work?

A humidistat measures the level of humidity in the air and when the level rises to a certain level the dehumidifier will switch on and start removing moisture from the air. The air is drawn in by a fan into the dehumidifier unit and through the rotating desiccant rotor, which adsorbs water molecules from the airflow. The resulting dry air is then channelled out of the dehumidifier unit.
Simultaneously, another fan sucks outdoor air, also called regeneration air, and through a heater and the rotating desiccant rotor. This heated airflow absorbs the water molecules in the desiccant rotor, thus, allowing it to continue drying the humid air. The resulting airflow also called wet air, is then channelled out of the dehumidifier unit and expelled out of the room.
When to buy a dehumidifier?

Buying a dehumidifier is an important step to improving indoor air quality. When humidity levels are high there are several moisture problems that you may detect in a room for instance;
-Condensation of walls or windows
-Fog and Icing in Cold Rooms
-Mould Growth on walls
-Increase in pest infestation
-Rust or rotting wood
-Musty Odours
You can use a hygrometer, to measure humidity, to determine how much dehumidification the room needs to stay at the optimum level for indoor air quality.
