How a Dehumidifier works?

Here is a brief overview of how a dehumidifier works:

  1. Air is drawn into the dehumidifier through a fan or blower.
  2. As the air passes over the cooled evaporator coil, the moisture in the air condenses into liquid form and drips into the dehumidifier’s water collection container.
  3. The dehumidifier‘s compressor compresses the refrigerant gas, which increases its temperature.
  4. The hot refrigerant gas is then passed through the condenser coil, which releases the heat to the surrounding air and cools the gas back down to a liquid.
  5. The cooled liquid refrigerant is then passed through an expansion valve, which lowers the pressure and temperature of the refrigerant, causing it to evaporate.
  6. The refrigerant vapor returns to the evaporator coil, where the process starts over again.
  7. The dehumidified air is then blown back into the room through the fan or blower.

The process of dehumidification continues until the desired humidity level is reached, at which point the dehumidifier will automatically turn off or enter a low-energy standby mode. Some dehumidifiers also have a built-in humidistat, which allows you to set the desired humidity level and automatically adjusts the dehumidifier’s operation to maintain that level.
