Types Of Dehumidifiers

Before you can go out and buy the best dehumidifier possible, you first need to know all of the different types of dehumidifiers that are out there. In the past, there were only one or two options available when you wanted to go buy one of these units. That just isn’t the case anymore. There are quite a few different types of dehumidifier models, and each of these different types have their own features which make them unique. Let’s take a few moments today and see some of the different dehumidifier models that are available today.

There are three basic types of dehumidifiers on the market today. These include heat pump dehumidifiers, chemical absorbent ones and ventilating dehumidifiers. Some people also use homemade dehumidifiers, but those aren’t going to get touched upon today because they don’t work as well as commercial models. Let’s take a closer look at these three dehumidifier models you are likely to encounter while reading dehumidifier reviews.

Heat Pump Dehumidifiers

These type of dehumidifiers—also known as refrigerant dehumidifiers—work by using a fan, a heat exchange and a heat pump to remove moisture from your air. This is the basics of how they work. Air is pulled into a unit by the fan and then passed over the heat exchange, or condensation coils. As the air passes over these cold coils, the moisture in the air is transferred from a gas into a liquid. This liquid is then expelled into a reservoir or through a drainage system. Meanwhile, the now drier air is warmed back to temperature by the heat pump and it is fed back into the room. These are perfect for most home applications.

Chemical Absorbent Dehumidifiers

This type of dehumidifier is very different from a heat pump one. It works by using some type of desiccant absorbent—usually silica gel—to absorb the moisture in the air. Here is how it works. Air is passed over this material and it absorbs the moisture. This moisture is then expelled via an outside vent. These type of dehumidifiers are often used in extremely hot areas and for industrial applications.

Ventilating Dehumidifiers

These are the simplest dehumidifiers of them all. All this device does is to pump the moist air from the room via an outside vent. They are usually fairly inexpensive but don’t work as well as chemical or heat pump dehumidifiers.

Those are the three basic types of dehumidifiers. However, from these three types there are hundreds of hundreds of dehumidifiers that all have different features. For a list of some of these features, I urge you to read some of my other articles that were written to clarify the subject a bit further.
