全球主要国家和地区制冷剂替代进展与展望

Progress and prospects of global refrigerant substitution

随着HCFCs加速淘汰阶段性目标的逐步完成,《蒙特利尔议定书》受控物质管控重点正在转向HFCs的削减。文章介绍了部分国家和地区制冷剂替代的现状和国际标准制修订进展,分析了未来可能的替代制冷剂和各类产品中未来可能的替代制冷剂选择方向。中国工商制冷空调行业应在开展充分的替代技术评估前提下,选择适合中国国情的替代技术路线,加大替代技术研发力度,藉此推动行业的技术进步与发展。

The focus of the controlled substances of the Montreal Protocol is shifting to the phase-down of HFCs,with the gradual completion of the phase-out target of HCFCs.This paper introduces the status of refrigerant substitution in some countries and regions and the revision progress of international standards,analyzes the possible alternative refrigerants and the possible substitution directions in various products in the future.Under the premise of full assessment of alternative technology,China's industrial and commercial refrigeration and air-conditioning sector shall choose the alternative technology route which is suitable for China,strengthen the research and development efforts,so as to promote the technical progress and development.
