• R-22 refrigerant has been used in air conditioning and refrigeration systems for many years. However, it is being phased out due to its negative impact on the ozone layer. Newer, environmentally friendly alternatives like R-410A are now more commonly used in modern HVAC systems.
  • R-410A refrigerant is commonly used in air conditioning and heat pump systems. It is part of a new generation of refrigerants that do not contain ozone-depleting substances. R-410A has become a popular replacement for the phased-out R-22 refrigerant, as it has a higher efficiency and does not contribute to ozone depletion. It is known for its better heat transfer properties, making it widely used in modern HVAC systems.
  • A2L refrigerant that falls into the category of lower flammability refrigerants. The “A” stands for “Azeotropic,” and the “2L” indicates lower flammability. Azeotropic refrigerants have a specific composition that remains constant during evaporation or condensation, which can be advantageous for certain applications. The “lower flammability” designation indicates that A2L refrigerants have a lower risk of flammability compared to some other flammable refrigerants. These refrigerants are being explored and adopted in the HVAC industry as part of efforts to transition away from high-global-warming-potential (GWP) refrigerants while considering safety factors related to flammability.
