How Does A Dehumidifier Work?

The Working Process of a Dehumidifier


A dehumidifier draws excess humidity and moisture from the air and helps to prevent condensation, mold growth and dampness. You will find two types of dehumidifiers in the market which are refrigerant and desiccant.

The work process of these two dehumidifiers is different which makes these suitable for different weather and environments.

Refrigerant Dehumidifiers


refrigerant dehumidifiersAnother name of refrigerant dehumidifier is compressor dehumidifier which inhales air over cold coils with a filter.

Then the water abbreviates on the coils and drips into the tank of the dehumidifier.

This type of dehumidifier is more effective for the heater rooms because it requires warmer air in the room than the surface inside it.

Also, the dehumidifiers’ coil can become freeze if the room temperature gets too low. In this situation the dehumidifier with automatically go into defrost mode and will consume energy and time to defrost rather than collect the water.

Desiccant Dehumidifiers


These dehumidifiers remove water from the air by using a heated adsorbent material. The heated absorbent material makes the moisture drop into the tank.

Desiccant dehumidifiers don’t depend on the temperature that is why they can work efficiently in any environment. So, you may use it in a conservatory, unheated basement or garage.

However, desiccant dehumidifiers may use more energy than refrigerant ones as they use the energy to heat the absorbent material.

If you are determined that you are always going to use a dehumidifier in a heated room you can go for the refrigerant. But if you are going to use the dehumidifier in an unheated room or both you should choose the desiccant.
