Dry All, a leading player in the HVAC&R industry, is at the forefront of innovation, consistently developing technologically advanced products to meet the evolving demands of the sector. With a commitment to quality, Dry All introduces its response to A2L refrigerants, aligning with the global shift towards low-GWP (Global Warming Potential) refrigerants.
Evolution of Refrigerants: A Historical Drive
The journey of refrigerants traces back to ancient times, progressing from natural ice to synthetic compounds like CFCs and HCFCs in the 19th century. Environmental concerns led to the development of HFCs, but their high GWP posed new challenges. The search for eco-friendly alternatives gave rise to low-GWP refrigerants, including A2L, marking a pivotal shift in the HVAC&R industry.
A2L Refrigerants: Understanding the Shift
A2L refrigerants, with their lower flammability and reduced GWP, present a viable alternative to high-GWP refrigerants like HFCs. Classified based on ASHRAE standards, these refrigerants contribute to the global effort to address climate change. The adoption of A2L refrigerants is a crucial step in reducing the carbon footprint of air conditioning and refrigeration systems worldwide.
A2L Refrigerants and GWP Values
The GWP values of various A2L refrigerants highlight their environmental impact. R32, R447A, and R454B are among the alternatives with significantly lower GWP values compared to traditional refrigerants. These replacements find applications in residential and automotive air conditioning systems, aligning with international agreements for phasing out high-GWP refrigerants.
A2L refrigerant with GWP value:
| Refrigerant | GWP |
| R452B | 676 |
| R32 | 675 |
| R447A | 500 |
| R454B | 466 |
| R454A | 238 |
| R454C | 146 |
| R455A | 145 |
| R1234ze | 6 |
| R1234yf | 4 |
Applications & who is replacing to whom:
