Compressor and Desiccant Dehumidifier: An Overview
When it comes to dealing with humidity in our living spaces or other environments, two common devices come to mind: the compressor dehumidifier and the desiccant dehumidifier. There are some key differences between them.
A compressor dehumidifier works in a way similar to a refrigerator. It has a compressor that pumps refrigerant through a system of coils. As warm, humid air is drawn into the dehumidifier, it passes over a cold coil. The moisture in the air condenses on the cold coil, just like how water droplets form on a cold glass on a hot day. The condensed water then drips into a tank, and the now drier air is reheated slightly and sent back into the room.
On the other hand, a desiccant dehumidifier uses a material called a desiccant, which has a natural affinity for water. The humid air is drawn into the unit and passes over the desiccant. The desiccant absorbs the moisture from the air. Some desiccant dehumidifiers then use a small amount of heat to dry out the desiccant so it can continue to absorb moisture. The dried air is then released back into the room.
One major difference between them is in their efficiency at different temperatures. Compressor dehumidifiers work best in warmer temperatures, usually above 15 - 20 degrees Celsius (60 - 68 degrees Fahrenheit). As the temperature drops, their efficiency decreases because the refrigerant may not cool the coil enough to condense the moisture effectively. In contrast, desiccant dehumidifiers can work well even at lower temperatures, making them a better choice for cooler environments such as basements in winter.
Another difference is in the level of humidity they can handle. Desiccant dehumidifiers can often reduce the humidity to a lower level than compressor dehumidifiers. So if you need to achieve very low humidity, like in a wine cellar or a storage room for sensitive items, a desiccant dehumidifier might be a better option.
Questions and Answers about Compressor and Desiccant Dehumidifier
Question: Which is more energy - efficient, a compressor dehumidifier or a desiccant dehumidifier?Answer: It depends on the temperature. In warmer temperatures (above 15 - 20 degrees Celsius or 60 - 68 degrees Fahrenheit), a compressor dehumidifier is usually more energy - efficient as it uses the principle of refrigerant cooling. However, in cooler temperatures, a desiccant dehumidifier may be more energy - efficient as the compressor dehumidifier's efficiency drops.
Question: Can a compressor dehumidifier be used in a cold basement?Answer: It can be used, but its efficiency will be low. Compressor dehumidifiers work best at warmer temperatures. In a cold basement, the cold temperature may prevent the refrigerant from cooling the coil enough to condense the moisture effectively, so a desiccant dehumidifier would be a better choice.
