Temperature-related devices have started using R417a refrigerant. While it is often marketed as a lower GWP alternative to R22, it’s important to note that R417a has a GWP of 1950. Although lower than R22’s GWP of 1600, it is still considered high. R417a is a blend of R600, R134a, and R125, and it serves as an alternative for R22, particularly in systems where compatibility with existing equipment is crucial. While it reduces some environmental impact, it does not qualify as a low GWP refrigerant by current standards, which typically classify refrigerants with GWPs less than 150 as low.

Exploring the Greener Alternative
As technology becomes more sophisticated, researchers always research to find better products. ‘Better’ doesn’t always refer to the instant and fast one, it could be the greener one. The journey from the natural to the instant one had happened a long time ago. Now, as nature has shown damage here and there, coming back to greener technology is a must. Here are interesting things to know about R417a refrigerant.
- R22 has a higher discharge temperature compared to the substitution. It means that with the substitution, the compressor doesn’t need to work hard. This part then gets later advantage that it lasts longer. Caution: not all systems give the same response to some material. Some system experiences efficiency, meanwhile others don’t. It is important to check the compatibility.
- This blend material can work well with new and conventional lubricants. Overall if it is compatible with the system, it can work efficiently and effectively with cost and energy savings as the bonus.
- The recharging process is very easy and doesn’t always have to stop the system.
The Application of R417a Refrigerant
It is used in temperature-related devices.
- Heat pump in water heaters: in the main heat pump, this blend acts as a mainstream cooler.
- Air conditioning: this new version can absorb hot temperatures and spray cold air. It creates a comfortable environment to make the inhabitants of a residence feel happy. In workplaces, comfort become the number one prominent thing because productivity relies on it.
- Refrigeration: food and beverage are two things that need it very much. People cannot always be interdependent and rely upon preservatives. Refrigeration as a physical preservative is also very important. Massive use of chemical preservatives could have bad effects. As one of the attempts to maintain health, reducing of the chemical preservatives use is a big step. Besides, some kinds of food can only work in cold states such as yogurt, etc.
While R417a refrigerant offers certain environmental benefits over older substances like R22, its Global Warming Potential (GWP) of 1950 still poses challenges for truly sustainable refrigeration practices. An even better alternative that is gaining traction due to its significantly lower environmental impact is R32 refrigerant. With a GWP of just 675, R32 not only reduces the potential for global warming more effectively but also enhances energy efficiency in systems.
Storage and Handling of R32 Compared to R417a
Like R417a, R32 also requires careful storage and handling due to its classification as an A2L refrigerant, indicating mild flammability. However, its superior thermodynamic properties mean that systems using R32 can be more compact and use less refrigerant overall, reducing potential environmental leakage risks. Storage conditions for R32 are similar to those for R417a, emphasizing cool, dry, and well-ventilated areas to prevent degradation or safety hazards.
The storage needs to avoid direct sunlight and sources of heat, as these can cause pressure increases that risk container integrity. For transportation, similar caution is advised to avoid damage or accidents, ensuring that the cylinders are securely stored and handled with care to prevent drops or collisions.
Integrating R32 into Sustainable Practices

Choosing R32 represents a step forward in aligning high-tech refrigeration and air conditioning systems with environmental sustainability goals. The lower GWP of R32 not only makes it a more attractive option for new installations but also for retrofitting existing systems where feasible. This move supports global efforts to reduce the impact of refrigerants on climate change while maintaining the comfort and technological advances crucial to modern life.
In conclusion, while R417a serves as a transitional refrigerant with certain advantages over R22, R32 emerges as a superior choice for those committed to minimizing environmental impact and fostering a sustainable future in refrigeration technology.
