If you have a dehumidifier, you might be wondering what refrigerant is used inside it. A refrigerant is a liquid that absorbs heat from an air stream and moves through the unit by the compressor, condenser and expansion valve/coil. The refrigerants used today are chlorine-free and ozone friendly.
Refrigerant is a liquid that absorbs heat from an air stream. It’s used in dehumidifiers, refrigerators and air conditioners to help keep food cold or heat comfortable.
In order to understand how this works you need to know about two things:
The first refrigerant was discovered in 1834 by William Day (1802-1859). It was called “sulfur dioxide” because it smelled like rotten eggs when it vaporized—not quite the most pleasant smell in your home! But this discovery led directly to the invention of another highly flammable substance: chlorofluorocarbons (CFCs).
Refrigerant moves in a cycle through the dehumidifier unit by the compressor, condenser and expansion valve/coil. The refrigerant used inside dehumidifiers is also known as r-22 or hcfc-22. R-22 was phased out in 2010 but you can still purchase new equipment with it if it was manufactured prior to that date. Chlorine-free refrigerants today include HFCs such as R410A and R134a, which are both halocarbon gases (meaning they contain halofluorocarbons).
The refrigerant used inside dehumidifiers is also known as R-22 or HCFC-22, a substance with a boiling point of -29 degrees Celsius. It absorbs heat from an air stream and moves through the dehumidifier unit by the compressor, condenser and expansion valve/coil.
R-22 was phased out in 2010 but you can still purchase new equipment with it if it was manufactured prior to that date. Chlorine-free refrigerants are now used instead of R-22 so you won’t need to worry about damaging your health or environment when using one!
There are several different types of refrigerants that can be used in a dehumidifier. The most common, and perhaps the most dangerous, is chlorofluorocarbons (CFCs). These chemicals were around for decades, but they are now being phased out due to their negative effects on the environment.
The following are some other types of refrigerants:
Hydrochlorofluorocarbons (HCFCs) – These chemicals do not damage the ozone layer like CFCs do; however, they have been found to contribute to global warming through their greenhouse gas emissions. They are also flammable and toxic at high levels so should be avoided when possible.* R134a – This type has been widely used since 1991 because it’s non-flammable and does not pose any health risks due its low toxicity levels compared with other gases.
HCFCs are chlorofluorocarbons, which are chlorine-based refrigerants. They’re also known as CFCs because of their chemical structure:
- Chlorine = Cl
- Fluorine = F
- Carbon = C
A refrigerant is a liquid that absorbs heat from an air stream. The process of cooling and dehumidifying the air begins with one or more compressor(s) which force refrigerant through a condenser, which cools it to its freezing point before returning it to be pumped back into the system by another compressor (or compressors). Refrigerants such as R-22 are typically used in domestic dehumidifiers because they’re easy to handle and inexpensive; however, there are other types available if you want something different than what we’ve discussed so far!
Dehumidifiers use refrigerants to cool air and remove humidity from the air. The refrigerants used inside dehumidifiers are also known as R-22 or HCFC-22, which is an AC refrigerant that is being phased out because of its high impact on the depletion of the ozone layer. The newer versions of these units have been designed without chlorofluorocarbons (CFCs), which were once a common ingredient in dehumidifiers but are now considered harmful to our environment.
