空气源热泵热水器全生命周期碳排放研究

Life cycle carbon emissions research of air source heat pump

将全生命周期评价方法应用于空气源热泵热水器的碳排放研究,将其全生命周期分为生产、使用和报废处理3个阶段,计算其各个生命阶段碳排放。结果表明:在其全生命周期各个阶段中,使用阶段的碳排放在总排放中具有最大贡献,超过97%。生产材料的使用原本会引起较大的排放量,但由于回收利用抵消了大部分的二氧化碳排放,因此降低其碳排放的主要措施为提高能效和运行节能。

Study on carbon emissions of life cycle assessment method which is applied to the air source heat pump water heater,the heat pump water heater full life cycle is divided into production,use and disposal,and the carbon emissions of every stage is calculated. The results showthat,use stage made the greatest contribution to total emissions,more than 90% at each stage in the whole life cycle of heat pump water heater. Use of production materials would cause large discharge amount,but the recycling offsets much of the carbon dioxide emissions,so the main measure to reduce its carbon emissions is improving energy efficiency and energy saving.
