摘要： 中国能源形势日益严峻。制冷空调行业的快速发展带来了巨大的能耗，也造成严重的环境问题。从节能减排出发，分析了通过制定中国制冷空调能效标准来逐渐控制和降低能源消耗。同时从臭氧层破坏和全球变暖出发，介绍了国际社会针对环境问题采取的对策以及环保型制冷剂的替代现状。从长远的环境保护考虑，自然工质尤其是CO2是必然趋势，最后介绍了CO2制冷技术的发展情况。

关键词: 节能减排, 能效标准, 制冷剂替代, 自然工质

Abstract: China has an increasingly severe energy situation. The rapid development of refrigeration and air-condition industry brings huge energy consumption and serious environmental problems. Based on energy conservation and discharge reduction, analysis of controlling and reducing energy consumption by formulating Chinas refrigeration and air-conditioning energy efficiency standards is presented. Moreover, because of ozone layer depletion and global warming, international response to environmental problems and refrigerant alternatives also are introduced. Natural refrigerants, especially CO2, will be future trends for environmental protection. Therefore, developments of CO2 refrigeration technology are introduced finally.

Key words: Energy conservation and discharge reduction, Energy efficiency standards, Natural refrigerants, Refrigerant alternatives
