Components of a Dehumidifier
These are the components of a dehumidifier found in most types of units:
- Fan Compressor
- Cooling Coils
- Reservoir (detachable water tank)
- Reheater
How Does a Dehumidifier Work?
Dehumidifier units are just like your home’s vacuum cleaner that sucks dust particles from the spot they’re being placed in. They absorb the air from the room and process it through the refrigerant coils, where the water droplets freeze and eventually fall into the water tub integrated into the bottom of the unit.
After that, the air is processed through the warm motor, which finally pulls the air into the room. Since this air is treated now, when it rolls back to the same process, it doesn’t handle it once again the same way due to lower relative humidity levels. That’s how the dehumidifier increases its efficiency and consumes less power the more it operates.
As mentioned earlier, the dehumidifier has trays/tubs at the bottom that collect the extracted water from the air. The portable or small units have normal-sized water collection buckets, while the industrial units have big buckets and hoses that can handle litres of water, draining them outside directly.
For instance, at AirXpress Hire, we offer portable dehumidifiers with a capacity of 3 litres per hour to 30 litres per hour – units that can efficiently handle diverse humidity issues with ease.
Types of Dehumidifiers
If you don’t know, dehumidifiers are categorised into two main types: refrigerant and desiccant dehumidifiers. Let’s learn how they differ in function.
Refrigerant Dehumidifiers
These are also known as compressor dehumidifiers, which work well in the summer season for domestic locations. The refrigerant units are reliable but can be a bit noisier in a quiet room. Their work is based on sucking air from the room and filtering it out through the coils to eliminate the moisture.
For instance, this type of dehumidifier is perfect for maintaining a relative humidity level between 40% and 60% in your home, apartment, or flat.
Desiccant Dehumidifier
On the other hand, we have the desiccant dehumidifier, which you may not hear about often. This is made to work in cold temperatures. Since the coil freezes when the temperature falls below 3 degrees Celsius in a compressor unit, the desiccant unit works well even in lower temperatures.
Although it consumes more electricity, it can extract excessive water vapour quickly. Thus, you’re always in a win-win position with this type of dehumidifier.
