R22 (also known as Chlorodifluoromethane or HCFC-22) is a hydrochlorofluorocarbon refrigerant that has been widely used for decades in air conditioning and refrigeration systems. It is known for its efficient cooling performance and compatibility with a broad range of equipment. Though phased out in many countries due to environmental regulations, R22 remains in use for servicing existing systems.
Key Features:
-
Proven Performance: Delivers reliable and efficient cooling for both residential and commercial systems.
-
Versatile Use: Compatible with many existing air conditioners, heat pumps, and refrigeration equipment.
-
Medium Pressure Refrigerant: Suitable for medium- and low-temperature applications.
Applications:
-
Window and split-type air conditioners
-
Central air conditioning systems
-
Commercial refrigeration units
-
Heat pumps
-
Industrial cooling systems
Environmental Considerations:
-
Ozone Depletion Potential (ODP): R22 contributes to ozone layer depletion and is regulated under the Montreal Protocol.
-
Global Warming Potential (GWP): R22 has a high GWP, making it less favorable compared to newer alternatives.
Important Notes:
-
Phase-Out Notice: Production and import of R22 are restricted or banned in many countries. It is primarily used for maintaining legacy equipment.
-
Handling Requirements: Requires certified technicians for recovery, recycling, and recharging.
Choose R22 only for servicing existing systems that were originally designed for it. For new installations, consider eco-friendly alternatives like R410A or R32.
