Under the global “dual-carbon” strategy and the push for green transformation1, refrigerants have become a crucial topic not only in the refrigeration industry but across the entire manufacturing sector. The choice of refrigerants directly impacts the performance of chillers, air conditioners, and refrigerators, while also influencing environmental protection, エネルギー効率, and sustainable development. Different countries, guided by varying policies and technologies, have formed their own “refrigerant maps.” As a pioneer in micro-environment cooling and high-precision temperature control, 冷却スタイル is leveraging R290-based compact chillers2 to strike a balance between safety, 効率, and sustainability.
私. Evolution of Refrigerants and Environmental Pressure
From CFCs in the mid-20th century, to HCFCs, then HFCs, and now low-GWP refrigerants3, the development of refrigerants is essentially a story of continuous innovation under the dual pressures of environmental regulation4 and technological progress.
Ⅱ. 冷媒の世界的な傾向
The choices made by different countries reflect differences in 環境基準5, technical maturity, safety regulations6, and cost considerations.
以来 2015, the EU has accelerated the phase-out of high-GWP refrigerants. に 2020, large-scale adoption of R2907 and other low-GWP refrigerants3 began. その間 R2907 delivers near “perfect” environmental performance, it also demands stringent equipment safety design, requiring companies to invest heavily in R&D for reliability.
の 2013, Japan led the global adoption of R328 in air conditioners, cutting the GWP nearly in half compared to R410A. 同時に, CO₂ has been widely used in refrigeration cabinets and heat pumps, earning Japan the reputation of a “CO₂ refrigerant leader9.”
の 2021, China joined the Kigali Amendment, committing to gradually reducing HFCs. The air-conditioning industry is rapidly shifting from R410A to R328, その間 R2907 is gaining momentum in chillers and other applications. As the world’s largest manufacturing hub, China’s transition is reshaping global market dynamics.
以来 2017, 米国. automotive industry has adopted R1234yf10 to replace R134a. これら HFOs11 are both environmentally friendly and safe, though higher costs and technical thresholds have slowed adoption in industrial applications.
- India: R32 and R290
India began promoting R32 air conditioners12 の 2013, followed by R290 in refrigerators13. With strong policy support and cost considerations, India has sought a balanced path between environmental responsibility and affordability.
Ⅲ. The Advantages and Challenges of R290
Among low-GWP refrigerants, R290 (プロパン)14 stands out for its unique strengths:
- Outstanding environmental performance15: With a GWP value of just 3, it has virtually no impact on global warming.
- Excellent thermal properties16: Comparable or superior to traditional refrigerants, with lower energy consumption.
- Wide applicability17: Especially suitable for compact chillers and commercial refrigeration equipment.
しかし, R290 is mildly flammable, which raises safety concerns. This requires enhanced system design, optimized piping, leak protection, and intelligent monitoring to ensure safe operation.
Ⅳ. Coolingstyle’s Leadership in Green Refrigerants
As an innovator in micro-environment cooling and high-precision temperature control, 冷却スタイル is at the forefront of the refrigerant transition.
- Early Adoption of R2907
以来 2024, Coolingstyle has integrated R2907 into its chiller R&D roadmap, firmly aligning with green development goals.
