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 industry players, including the State Environmental Protection Administration, the Chinese Institute of Refrigeration, as well as leading companies such as Trane, Carrier, McQuay, Johnson Controls, Dalian Bingshan, Yantai Binglun, and Qingdao Haier HVAC. The forum aimed to discuss the transition away from HCFCs and explore new refrigerant technologies. 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 main sections, each highlighting key developments and opportunities in the refrigerant industry. First, Mr. Zhang discussed R410A, focusing on its features and cost implications. He outlined several factors that are expected to drive the rapid growth of R410A systems: - **Environmental regulations**: Following the Montreal Protocol meeting on September 16, 2007, China committed to a specific timeline for phasing out HCFCs. - **Energy efficiency standards**: New energy efficiency regulations require existing standards to be upgraded by two grades, making R410A and R22 systems nearly comparable in cost. - **System advantages**: R410A systems are more compact and quieter, appealing to a broader range of users. - **Market expansion**: Many companies are now developing R410A small chillers, further expanding its application in the market. Second, he presented on low GWP refrigerant H, specifically for automotive air conditioning. Through physical property analysis, compatibility testing, and prototype evaluation, the following conclusions were drawn: - **Safety and environmental impact**: Fluid H is non-flammable and has a very low global warming potential (GWP), with promising performance results. - **Performance comparison**: Initial tests showed that Fluid H performs similarly to R134a. Any minor reduction in cooling capacity can be addressed through adjustments like changing the expansion valve or optimizing the evaporator design. - **Material compatibility**: Early tests did not reveal any issues, but further research is needed to ensure long-term reliability. - **Potential replacement**: Fluid H shows great promise as a cost-effective and high-performance alternative to R134a. Finally, Mr. Zhang introduced Honeywell’s high-temperature working fluid, HAS09. As part of Honeywell Specialty Materials, which is based in Morristown, New Jersey, the company is a global leader in specialty materials, generating annual revenues of $4.7 billion. Their product portfolio includes fluoropolymers, specialty films, advanced fibers, and a wide range of chemical solutions used across multiple industries, including refrigeration and petroleum refining. The forum provided valuable insights into the future of refrigerant technology, emphasizing the importance of sustainable and efficient alternatives in the face of growing environmental and regulatory pressures.
