【摘要】：我国居民家庭空调拥有量迅速增加,其生命周期中产生的温室效应也日益受到关注.本文依据国际标准PAS 2050,采用RCEES 2012和Ecoinvent 2.1数据库,并运用SimaPro 7.1软件计算了中国典型家用空调的碳足迹.主要结论为:家用空调生命周期中使用阶段用电产生的碳足迹最大,占67%;制冷剂的泄漏是除电力使用外第二大碳足迹贡献因素,产生了23%的碳足迹;生产制造阶段和废物处理阶段的碳足迹分别占16%和-6%.敏感性分析表明,空调日使用时间、空调年使用季节和制冷剂的泄漏比例是家用空调碳足迹的关键影响因素.
[Abstract]:China's household air conditioning has a rapid increase in the amount of greenhouse effect, its life cycle is also increasingly concerned. On the basis of the international standard PAS 2050, using RCEES 2012 and Ecoinvent 2.1 database, and China typical household air carbon footprint was calculated by using SimaPro 7.1 software. The main conclusions are as follows: the use of air conditioner in the life cycle stage the electricity generated carbon footprint, accounting for 67%; the leakage of refrigerant is in addition to electricity use second carbon footprint contribution factors, resulting in a 23% carbon footprint; carbon footprint manufacturing stage and waste disposal stage respectively accounted for 16% and -6%. sensitivity analysis showed that the use of air conditioning, air conditioning, leakage of the proportion of time in the use of the season and refrigerant are the key factors that affect the household air-conditioning carbon footprint.
