How Refrigerant Works

Without refrigerant, there would be no air conditioning, refrigeration or freezing technology.

Air conditioners contain refrigerant inside copper coils. As 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.

Types of Refrigerants

The most common refrigerants used for air conditioning over the years include:

  • Chlorofluorocarbons (CFCs), including R12. T
  • Hydrochlorofluorocarbons (HCFCs), including R22.
  • Hydrofluorocarbons (HFCs), including R410A and R134. With no chlorine in the mix, this is safer for the environment and is now being used in place of R22. Air conditioners that run on R410A are more efficient, offer better air quality, increase comfort and improve reliability. We carry  R410A and R134. at LL Supply Ltd.
