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.
