With the phase-out of HCFCs being hastened in several parts of the world, most notably UAE, many research on two alternatives to R22, namely R407C and R410A, have been conducted. However, a third possibility, R417A, which combines R125, R134a, and R600, is developing as a possible replacement for R22.

R417A is an HFC retrofit refrigerant for R22 indirect expansion of stationary air conditioning (AC) and medium temperature commercial refrigeration systems.

Properties of R417A Refrigerant Gas 

The physical parameters of R417a are comparable to those of R22 refrigerant. It’s best for replacing R22 in small fixed air conditioning systems (under 15 kW). Because R417A contains 3.4 wt% R600, it does not require synthetic oil (butane). R600 is a fantastic oil carrier. 

Because of this, R417A refrigerant gas can be used as a pure drop-in replacement for current R22 equipment without requiring any modifications. It’s also ideal for commercial refrigeration systems with medium/high temperatures, such as DX coolers.


This refrigeration gas has a low viscosity and surface tension, as well as a high density and low boiling point. It has good chemical and thermal stability, as well as the ability to be delivered as liquefied gas in low-pressure cylinders. 

Without fluorocarbon refrigerants, many modern refrigeration and HVAC applications would be impossible to implement.


  • Provides cost-effective and efficient retrofits.
  • It has HFCs that do not cause ozone layer depletion
  • In most circumstances, there is no need to alter the lubricant type during the refit because it is compatible with both old and new lubricants.
  • Allows existing equipment to be used.
  • Can be topped up without removing the entire refrigerant charge during service.


  • Residential, industrial, and commercial AC systems
  • Medium-temperature commercial refrigeration, including:
  • Foodservice
  • Supermarket display cases
  • food storage and processing

Performance Evaluation

When compared to R-22, the discharge temperature and pressure are significantly lower, extending the compressor’s life. In most systems, the cooling capacity is sufficient. It has been demonstrated to save energy.

Possible Hazards:

  • In high quantities, asphyxiant
  • Low temperatures will result from rapid expansion.
  • When handling cylinders, use safety goggles, protective gloves, and overall, and safety shoes.
