Humidity, the volume of water vapour present in the air, may appear like a small issue, but it may result in severe problems if left unaddressed. Whether it is in your residence or workplace, increased humidity may cause the following:
- Mould Growth
- Damage to Furniture
- Peeling Paint
- Structural Issues
Dehumidifiers are necessary tools to tackle these issues. Nevertheless, not all dehumidifiers are the same. In this informative blog, we will explore the major differences between compressor dehumidifiers and desiccant dehumidifiers, aiding you in making a smart decision for your requirements.
Why is Humidity an Issue?
Before delving into the dehumidifier types, it is important to comprehend why humidity is such an issue. Excessive humidity levels can establish an environment where mould and mildew grow, resulting in health problems and foul smells. It can also harm your property by causing paint to peel, wallpaper to loosen, and wooden furniture or floors to rot. In extreme cases, high moisture may even compromise the structural stability of walls and brickwork. These problems are not only expensive to repair but can recur if the root cause—excessive humidity—is not handled.
How Does a Compressor Dehumidifier Work?
Compressor dehumidifiers, otherwise called refrigerant dehumidifiers, have a similar operating mechanism as that of air conditioners. Here is a step-by-step breakdown of how they operate:
Air Intake: The unit pulls in damp air from the external environment.
Cooling Process: The air passes over cold evaporator coils filled with refrigerant. These coils are colder in comparison to the incoming air which causes the moisture in the air to condense into evaporator pipes.
Water Collection: The condensed water drips off the evaporator pipes and collects in a built-in water tank.
Refrigerant Cycle: The refrigerant, now evaporated into a gas, is compressed by the compressor, enhancing its pressure and temperature.
Heat Dissipation: The hot gas flows through condenser coils, losing heat and returning to a liquid state.
Air Exhaust: The air is blown over both the evaporator and condenser coils, ensuring the exhausted air remains at a similar temperature before being released back into the room.
One major feature of compressor dehumidifiers is that they retain the air temperature while eliminating moisture. This makes them perfect for warmer climates, where they can work effectively.
How Does a Desiccant Dehumidifier Work?
Desiccant dehumidifiers take an entirely different approach to the removal of moisture. Instead of utilising refrigerant coils, they count on a moisture-absorbing material that is referred to as a desiccant. Here is how they operate:
Air Intake: Damp air is drawn into the unit.
Moisture Absorption: The air passes over a rotating wheel coated with desiccant material, chemically absorbing moisture from the air.
Regeneration: A portion of the desiccant wheel is heated for releasing the absorbed moisture, which is either collected in a water tank or expelled as water vapour.
Air Reheating: The dry air is reheated and emitted back into the room.
Desiccant dehumidifiers are acknowledged for their capability to work efficiently at low temperatures, making them appropriate for cooler environments.
Major Differences Between Compressor and Desiccant Dehumidifiers
Now that we have covered how each type operates let’s examine the major differences to help you determine which one is right for your requirements.
1. Working Temperature
Compressor Dehumidifiers: These units perform well in warm environments, usually above 20°C. At low temperatures, the evaporator coils may freeze, leading to decreased efficiency.
Desiccant Dehumidifiers: These are more flexible and can work well in cooler temperatures.
2. Energy Consumption
Compressor Dehumidifiers: Typically, more energy-efficient, specifically in hot conditions. They can save up to 50% more electricity in comparison to desiccant models.
Desiccant Dehumidifiers: Tend to consume higher energy because of the heating element utilised to regenerate the desiccant. Nevertheless, the heat they release can prove useful in cooler places.
3. Noise Levels
Compressor Dehumidifiers: These units are noisier, usually operating at over 45dB because of the compressor and fan.
Desiccant Dehumidifiers: Quieter during the operation, with noise levels as low as 35dB.
4. Maintenance Requirements
Compressor Dehumidifiers: Need more maintenance because of the compressor and refrigerant system. Routine cleaning of coils and filters is essential.
Desiccant Dehumidifiers: Simpler in design, needing less regular maintenance. Nevertheless, the desiccant material might require replacement in the course of time.
5. Portability
Compressor Dehumidifiers: Heavier, usually weighing 10kg or more, making them harder to move around.
Desiccant Dehumidifiers: Lighter, generally weighing between 5kg and 9kg, making them more portable and simpler to relocate.
6. Space Requirements
Compressor Dehumidifiers: More suitable for larger spaces because of their greater capacity. For instance, few models can remove a considerable amount of moisture per day.
Desiccant Dehumidifiers: More compact and superior for smaller spaces. Nevertheless, their capacity is limited, so they might be less efficient in larger or intensely humid regions.
7. Cost
Compressor Dehumidifiers: Usually more economical upfront, though maintenance costs can increase as time goes by.
Desiccant Dehumidifiers: Tend to have a higher initial cost but might save on maintenance expenditures in the long term.
Which One Should You Select?
The choice between a compressor and a desiccant dehumidifier depends on your particular requirements and environment. Here are a few scenarios to help you determine:
Select a Compressor Dehumidifier If:
- You live in a warm or humid climate.
- Energy efficiency is a priority.
- You require a unit for bigger spaces with moderate to high humidity levels.
Select a Desiccant Dehumidifier If:
- You require a dehumidifier for cooler environments.
- Noise levels are a concern.
- Portability is important, and you require a lighter unit.
To Sum Up!
Both compressor and desiccant dehumidifiers have their particular advantages and are ideal for use in different conditions. Compressor dehumidifiers do well in hot, humid conditions and are more energy-efficient, while desiccant dehumidifiers are better for cooler environments and offer quieter operation. By comprehending the differences, you can choose the correct dehumidifier to safeguard your residence or workplace from the adverse effects of high humidity.
