Technical Specifications

Freon NU-22B R-422B Applications

Residential Air Conditioning

Freon NU-22B can be used as an R-22 replacement in suitable residential direct-expansion air-conditioning systems. Freon identifies NU-22B specifically as a refrigerant that closely mimics R-22 operating characteristics in many residential AC systems.

Commercial Air Conditioning

Commercial buildings with existing R-22 HVAC equipment may use Freon NU-22B as a retrofit refrigerant where the system and application are suitable. Freon lists NU-22B among its refrigerants for commercial air-conditioning applications.

HVAC Maintenance and Retrofit

Freon NU-22B is particularly relevant for HVAC contractors and service companies maintaining existing R-22 equipment. The manufacturer’s retrofit guidance provides procedures for converting suitable R-22 direct-expansion systems.

Existing R-22 Equipment

The product is intended for compatible existing systems rather than as a universal replacement for every R-22 installation. System-specific retrofit procedures and manufacturer/OEM requirements should always be reviewed before conversion.

Freon NU-22B R-422B Retrofit

Freon NU-22B is designed as a retrofit refrigerant rather than a refrigerant that should simply be mixed with R-22.

The manufacturer’s retrofit guidance states that R-22 should be recovered before conversion and that refrigerants should not be mixed. The system should then be properly prepared, evacuated, charged, and commissioned according to the applicable retrofit procedure.

Oil Compatibility

One of the important advantages of Freon NU-22B is its compatibility with mineral oil and other lubricants used in suitable R-22 systems. In many retrofit applications, the existing lubricant can remain in service without a complete oil change. However, oil return depends on system design and operating conditions, so the manufacturer’s retrofit guidelines should be followed.

Refrigerant Charge

The manufacturer’s FAQ indicates that the initial NU-22B charge may generally begin at approximately 85–90% of the original R-22 charge, followed by system stabilization and adjustment according to the required operating conditions. The final charge depends on the particular system.

Gauge Compatibility

Freon states that NU-22B and R-22 have similar pressure characteristics, allowing the same gauge sets to be used for applicable service work.

Freon NU-22B Performance

Freon NU-22B is designed to provide similar operating characteristics to R-22 in suitable applications. Manufacturer technical data indicates that NU-22B can provide similar cooling performance and energy efficiency to R-22 in many properly retrofitted systems, while operating at a lower compressor discharge temperature.

Performance is dependent on:

• Compressor type
• Condenser and evaporator design
• Ambient temperature
• Evaporating temperature
• Condensing temperature
• Refrigerant charge
• Expansion device
• Lubricant and oil return
• System cleanliness
• Operating conditions

Therefore, published performance figures should not be treated as guaranteed results for every installation.
