摘　　要：阐述了采用H2O为制冷剂的溴化锂吸收式冷水机组及热泵在臭氧层保护和抑制气候变暖方面具有显著的优势,并对进一步减少CO2的排放技术进行了课题探讨。另外在采用HFCs替代HCFCs制冷剂的实践应用中,从综合温室效应指数TEWI的角度指出了优化选用制冷剂、提高系统效率,减小系统制冷剂的充注量和泄漏率,加强对废旧产品中制冷剂的回收是减少使用HFCs制冷剂直接产生温室效应的必要手段。It was pointed that LiBr absorption chiller and heat pump using H2O as refrigerant have obvious advantages in protecting ozonosphere and preventing climate change,and probed into optimized CO2 emission reduction technology.Moreover,in the alternative practice of HFCs replacing HCFCs refrigerant the paper pointed out the optimized refrigerant,increasing system efficiency,decreasing system refrigerant filling amount and leak rate,enhancing deserted products refrigerant recycle is necessary in decreasing greenhouse effect resulted by using HFCs as refrigerant.
