A dehumidifier works by drawing warm air currents into its coils via a fan. Warm air contracts as it passes through the machine's refrigerated coils, and condensation forms inside the dehumidifier.
Here are the 6 steps of the whole air humidification process:
-
The compressor propels the fan and the flow of the refrigerant.
-
The fan draws humid air into the dehumidifier via an air inlet.
-
The humid air is met with a series of very cold coils (basically, a refrigerator). There the water from the air is condensed on the cold coils.
-
The drip tray gathers the water in the water tank. The convenience of removing water from the dehumidifier’s water tank will be one of the key parts of the buying guide below.
-
The now dry cold air will run over hot coils to warm up (basically, a heater).
-
The same fan that absorbs the humid air into the dehumidifier will now propel the dry air out.
Basic Dehumidifier Working Principle
Extract moisture out of the air: Fan in the moist air in the house, run it over a cold coil (Evaporator) which condenses moisture out of that air, and collects the water via a drip tray into a water tank. We end up with cold but dry air.
Heat the dry air back up: Run the cold but dry air over a hot coil (Condenser) to bring it up to room temperature. Fan the dry air back in the house.
