Similar to the working principle of any refrigerator, the dehumidifier works on the same principle. It is an electrical gadget, with cooling coil and heating coils inside. The moist air is sucked inside the dehumidifier, and it circulates over the cold coil. The sucked air condenses on the coil and forms water droplets which get accumulated in the water tank or thrown outside through proper drainage pipeline. The air then passes over the heating coil getting completely dry and warm and thrown out by the dehumidifier inside the room to give a soothing air maintaining a proper indoor atmosphere.

These all can be controlled if one uses a dehumidifier at home.
