Refrigerant is a compound typically found in either a fluid or gaseous state. It readily absorbs heat from the environment and can provide refrigeration or air conditioning when combined with other components such as compressors and evaporators. If you’ve heard about the R22 refrigerant phaseout in favor of R410A refrigerant, you might be especially interested to know more about how refrigerant works and what part it plays in cooling your home.
How Refrigerant Works
Without refrigerant, there would be no air conditioning, refrigeration or freezing technology.
Air conditioners contain refrigerant inside copper coils. As the refrigerant absorbs heat from indoor air, it transitions from a low-pressure gas to a high-pressure liquid. Air conditioning components send the refrigerant outside where a fan blows hot air over the coils and exhausts it to the exterior.
The refrigerant then cools down and turns back into a low-pressure gas. Another fan located inside the home blows air over the cool coils to distribute the resulting cold air throughout the building. Then the cycle repeats.
