R422B Refrigerant Applications

HVAC/R professionals use R422B in compatible air-conditioning, heat-pump, refrigeration, and other systems where equipment specifications and applicable regulations permit its use.

Typical applications may include:

• Residential air-conditioning systems
• Light-commercial air-conditioning systems
• Heat-pump systems
• Certain commercial refrigeration systems
• Remote condensing units
• Industrial process refrigeration
• Very-low-temperature refrigeration
• Compatible retrofit applications
• Other HVAC/R equipment approved for R422B

Before selecting or charging R422B, always verify the equipment manufacturer’s specifications and applicable regulatory requirements.

EPA currently lists R422B as acceptable under SNAP for residential and light-commercial air conditioning and heat pumps, industrial process refrigeration, remote condensing units, and very-low-temperature refrigeration.

R422B Refrigerant Properties

EPA currently lists R422B with GWP 2,530, ODP 0 and A1 safety classification.

R422B for Air Conditioning and Heat Pumps

For example, HVAC/R professionals may use R422B in compatible residential and light-commercial air-conditioning and heat-pump systems when system design and applicable requirements allow its use.

EPA currently lists R422B as an acceptable substitute in the residential and light-commercial air-conditioning and heat-pump end-use.

However, technicians should always verify system compatibility, operating requirements, refrigerant charge, and manufacturer recommendations before servicing or converting equipment.

R422B as an R22 Alternative

R422B has been used in certain applications as an alternative to R22 in compatible systems.

However:

R422B should not be marketed as a universal direct drop-in replacement for R22.

Before converting an R22 system to R422B, a qualified HVAC/R professional should evaluate:

• Compressor compatibility
• Existing lubricant
• Expansion devices
• Refrigerant charge
• Operating pressures and temperatures
• Seals and system components
• System capacity and performance
• Equipment manufacturer recommendations
• Applicable EPA requirements

Therefore, technicians should evaluate the complete system before performing a refrigerant conversion.

R22 alternative for compatible retrofit applications

EPA notes that retrofits to alternative refrigerants are allowed when the alternative is acceptable for that end-use, but system/component changes may be necessary for proper operation.

R422B Charging and Service Considerations

Because R422B is a refrigerant blend, technicians should follow the refrigerant manufacturer’s charging procedures and equipment service requirements.

For typical service applications, technicians generally charge R422B from the cylinder in the liquid phase to help maintain the intended blend composition.

Always follow the cylinder label, SDS, equipment manufacturer guidance, and established HVAC/R service procedures.

R422B and Current U.S. Equipment Restrictions

Although EPA continues to list R422B as acceptable for several HVAC/R end uses, its use is restricted in some categories of newer equipment.

For example:

• R422B became unacceptable in new cold-storage warehouse equipment beginning January 1, 2023.
• EPA restricts R422B in several categories of new stand-alone commercial refrigeration equipment.
• R422B is generally unacceptable in certain new positive-displacement and centrifugal chillers beginning January 1, 2024, except where a narrowed-use provision applies.

U.S. Refrigerant Purchase Requirements

R422B is an HFC refrigerant intended for stationary HVAC/R applications and is subject to U.S. refrigerant sales restrictions.

EPA states that refrigerants for stationary refrigeration and air-conditioning equipment generally may only be sold to Section 608-certified technicians or other qualifying purchasers allowed under the regulation. Sellers are also responsible for purchaser verification and required sales records.

Important Use Information

Qualified HVAC/R professionals should handle, recover, charge, and use R422B in accordance with applicable regulations, equipment manufacturer requirements, and established service procedures.

Always confirm that R422B is approved and legally permitted for the specific equipment and end use before servicing or converting a system.

For current U.S. refrigerant application requirements, refer to the U.S. EPA SNAP Refrigeration and Air Conditioning guidance.
