Operation of the Dehumidifier
Operation of Humidifier , How to use Dehumidifiers and Dehumidifier, sometimes abbreviated as DEH or DH , is a removal of water from the air in the building. . The dehumidifier is a reduction of humidity with the aims to maintain comfort and protect construction materials. There are two principles method of dehumidification namely, use of heat pump the refrigerant and Desiccant Dehumidifier. (The water molecules are attached to the surface of the material)
1. Mechanical Refrigeration system Moist air flow through the metal coil, evaporator, and the moisture is condenses on the coil and collected in a reservoir or drain off . Then, the dry air of heat pump flows through the condenser of the heat pump where the warm air is discharged via a fan to the outside.
2. Desiccant Dehumidifier It will transfer the moisture flow through the porous wheel, which is made of desiccant material, such as silica gel, activated carbon to absorb water molecules. After the water has passed through desiccant rotor continuously move moisture inside the wheel, it is exposed to reactivated air . Wheel absorbs moisture is exhausted out building.
