On December 7, 2007, the International Forum on ODS Phase-Out and Alternative Technology Development for HCFCs took place at the Nikko Hotel New Century in Beijing. Organized by the China Refrigeration and Air-Conditioning Industry Association, the event brought together over 200 representatives from various companies, including the State Environmental Protection Administration, the Chinese Institute of Refrigeration, and leading industry players such as Trane, Carrier, McQuay, Johnson Controls, Dalian Bingshan, Yantai Binglun, and Qingdao Haier HVAC. During the forum, Mr. Zhang Ke from Honeywell's Special Materials Department delivered a keynote speech titled "Development and Application of Efficient Refrigerants and High Temperature Heat Pump Working Mediums." His presentation was divided into three key sections, each addressing important developments in refrigerant technology and environmental compliance. First, he discussed the features and cost implications of R410A in home air conditioning systems. He highlighted that R410A is expected to experience rapid growth due to several factors: the Montreal Protocol's specific timeline for phasing out HCFCs, new energy efficiency standards that will raise existing benchmarks by two levels, making R410A and R22 systems nearly cost-competitive, and the system’s compact design and quieter operation, which appeal to a wide range of users. Additionally, many manufacturers are now developing R410A small chillers, expanding its applications across the industry. Next, Mr. Zhang introduced a low-GWP refrigerant for automotive air conditioning known as Fluid H. Based on physical properties, compatibility tests, and prototype evaluations, he noted that Fluid H is non-flammable and has an extremely low GWP. Initial test results showed performance very close to R134a, with minor cooling capacity reductions that can be addressed through adjustments like modifying the expansion valve or optimizing heat exchanger design. The material compatibility tests so far have shown no issues, though further testing is recommended. Overall, Fluid H is considered a promising alternative to R134a, offering better cost and performance benefits. Finally, he presented Honeywell’s high-temperature working fluid, HAS09. As a global leader in specialty materials, Honeywell Specialty Materials, based in Morristown, NJ, generates annual revenues of $4.7 billion. Their product portfolio includes fluoropolymers, specialty films, additives, advanced fibers, intermediates, and more. HAS09 represents a significant advancement in high-temperature applications, providing efficient and environmentally responsible solutions for industrial and commercial use. The forum provided valuable insights into the future of refrigerants and sustainable technologies, emphasizing the importance of innovation and regulatory compliance in the industry.
