提出一种社会化的生命周期评价(LCA)方法,取代经典的ISO-LCA方法优化家庭的洗涤。采用实际调查及人工污布试验的方法,研究了由于最近人们的生活方式、洗衣机的节能化和洗涤剂浓缩化等因素引起的洗涤过程的变化,比较了不同年代、不同容量的全自动洗衣机对洗涤的影响,对洗涤过程中的洗涤剂、用水和耗电量进行了社会化的LCA分析。研究表明,最近制造的节水型全自动洗衣机已大大减少了CO2排放量,并指出减少洗涤过程CO2排放量的途径。 Proposed a social life-cycle assessment (LCA) method to replace the classic ISO-LCA method to optimize household washing. Using the method of actual investigation and artificial fouling test, the changes of washing process caused by the recent people’s lifestyle, energy-saving washing machines and concentration of detergents were studied, and the comparison of different automatic washing machines with different capacities and different capacities The impact of washing, LCA analysis of detergents in the washing process, water use and power consumption. Research shows that recently manufactured water-saving fully automatic washing machines have significantly reduced CO2 emissions and pointed out ways to reduce CO2 emissions during the washing process.
