R22 is a widely used hydrochlorofluorocarbon (HCFC) refrigerant, ideal for air conditioning and refrigeration systems. Known for its reliable performance, it has been phased out in many regions due to its ozone depletion potential but remains a critical option for servicing older systems still in operation.

R22, also known as chlorodifluoromethane, is a highly efficient refrigerant commonly used in air conditioning and refrigeration systems worldwide. Although it has been phased out in many countries due to its ozone depletion potential (ODP), it remains in use for servicing existing systems that are not yet retrofitted to more environmentally-friendly alternatives. R22 operates efficiently under both high and low-temperature conditions, making it ideal for residential, commercial, and industrial cooling systems.
In systems still using R22, it is crucial to ensure that the refrigerant is properly maintained to avoid leaks, as this can increase the environmental impact. Since R22 has a high Global Warming Potential (GWP), it is being replaced by more eco-friendly refrigerants like R407C and R410A in new installations and retrofits. However, for those needing to service existing systems, R22 remains a reliable and cost-effective solution.
R22 refrigerant is typically used with mineral oil lubricants, and in systems still in operation, it is important to manage the oil levels and refrigerant charge for optimal performance.
Applications:
✅Residential HVAC Systems: Used in residential air conditioning systems that were originally designed for R22.
✅Commercial Refrigeration: Common in older commercial refrigeration applications like display cases, cold storage, and foodservice units.
✅Industrial Cooling: Suitable for large-scale industrial refrigeration systems and air conditioning units where retrofitting has not yet been completed.
