What Does A Dehumidifier Do

Being in a room that is too humid can be downright uncomfortable.  Not only does it wreck your hairdo, but it can also make you feel lazy and lethargic.  Because of this fact many people are opting to use a dehumidifier in their homes or offices, in an attempt to balance the relative humidity of the air around them.  However, some folks just don’t understand what the machine does or how it can be beneficial.

Components of the Dehumidifier

In order to get the most out of any dehumidifier, you will need to know and understand how the basic components are assembled.  Although these machines are usually available in a variety of styles and designs, the foundational mechanisms are all pretty much the same.  The average machine has four basic components to it:

  • Re-heater
  • Fan Compressor
  • Compressor Cooling Coils
  • Reservoir

This simple design helps the dehumidifier do its job without causing you massive headaches.  Because adding or removing moisture from the air is a relatively simple task, these machines can come with a myriad of options.  Regardless of the model you choose, you will also need to understand how the machine works.

How it all Works Together

The mechanical components of the average dehumidifier are rather simple; and so too is the actual inner workings of the machine as a whole.  If you have ever wiped condensation from the outside of a glass, you are halfway to understanding how it all works together.  So, what exactly does a dehumidifier do?

First, a fan collects moist air from your surroundings.  As this wet air passes through the machine, it is met by the cooled coils inside.  These coils then use the principles of condensation to exploit the properties of water, actually pulling the moisture from the air.  The reservoir inside the machine then catches the drips of water coming off the cooled coils, while the dehumidifier reheats the air, blowing it back into the room.

This simple process happens all around us in nature every day.  It is this process reversed that caused the air to become overly moist in the first place.  Having and using the latest and greatest dehumidifier model will help ensure that you remain more comfortable throughout the day or night.  However, it is extremely important that you know how to use one properly, especially considering the use of electricity and water in such close proximity.

Safety and Responsible Use

Because a standard dehumidifier collects moisture from the air via condensation, the reservoir within the machine may need to be emptied often.  In some cases, higher end models are sold with a direct-line drain feature, freeing up some of your time to enjoy the newly dried air.  However, if you decide to use your machine in extremely moist places, or if you need to have it on for extended periods of time, then you should think about purchasing one with a built-in pump specially made for removing the internal condensate.

What’s more, you should also look for a dehumidifier with an automatic shut-off option, like the Frigidaire FAD504DWD Energy Star 50-pint Dehumidifier.  This will help to keep you safe while you enjoy the benefits of your machine.  Try also to locate a model that has a humidistat: a tool that uses a sensing element and a relay amplifier to allow for the personalized setting of spatial moisture levels.  As always, turn off or unplug your dehumidifier when it is not in use to prevent accidents.  If you can find models with these components, then you should be able to enjoy the benefits of your machine with little effort or concern.
