How does a dehumidifier work?

Dehumidifiers use the thermodynamics of refrigeration to extract moisture from the atmosphere. These refrigerant dehumidifiers consist of four basic parts: fan compressor, reheater, reservoir, and compressor cooling coils. The fan compresses and then expands the refrigerant to cool the coils. The reheater captures the heat that is produced during the cooling process. The coils are filled with refrigerant. The reservoir of refrigerant dehumidifier holds the moisture extracted from the air.

Another common unit is the desiccant dehumidifier, which is operated by moisture absorption. The substance used in this unit helps reduce the humidity by absorbing water vapors. Note that mechanical desiccant appliances blow air over the substance, such as bentonite clay or silica gel.

Best Capacity

When buying a dehumidifier for your RV, consider the unit’s bucket size before making the purchase. Note: dehumidifiers that consist of larger drip pans and tubs are emptied less often than smaller ones.

Appliances with larger tubs are more convenient. If the tank overfills and starts leaking out onto the floor, you have traded one version of water damage for another! Some even run small drain hoses to the outside of the RV and therefore no tub to empty, so maintenance is greatly reduced.

Also, keep in mind is that the more water your dehumidifier can extract and hold (the more capacity), the more costly it will be. If you are willing to spend more, get a dehumidifier that has front-loading buckets. These types of dehumidifiers are easier to empty.

Small or Big Space to Dehumidify?

Make sure to choose a dehumidifier that offers automated controls for setting and monitoring your RV moisture levels. The ideal humidity levels should remain between 20-50% in winters and 40%-50% in summers in your travel trailer.

Dehumidifiers that have hygrometers can measure optimal humidity and show the levels. Some dehumidifiers possess a flexible humidistat option. It allows you to set the desired humidity level so that your dehumidifier maintains the required levels of humidity in your RV 24/7.

Noise Level

Keep in mind that noise can create a nuisance, especially when traveling or staying in your RV. Therefore, it is essential to look for the dehumidifiers that have two-speed fans, which run quietly. These dehumidifiers can also save on energy costs. Making them one of the best RV dehumidifiers for a quiet night’s sleep.
