基于生命周期评价的FFU碳足迹分析

Analysis on Carbon Footprint of FFU Based on Lifecycle Assessment

碳足迹作为评估产品碳排放的量化指标,已成为低碳经济产业中重要的考量因素。风机过滤单元(FFU)由于应用范围广、能耗占比大等特点,其碳足迹研究具有重要意义。基于生命周期评价方法(LCA),依据碳足迹国际标准PAS2050的“从摇篮到大门”模型,研究FFU全生命周期内的碳足迹。基于使用运行阶段不同能耗预测模型的计算分析,一台FFU全生命周期内碳足迹为5376.6kgCO_(2)e或6873.7kgCO_(2)e。其中,运行阶段碳排放占比96%以上。因此,降低运行阶段的能耗是降低FFU全生命周期碳足迹的主要措施,这对FFU的使用运行环境、高效/超高效空气过滤器的动态性能、FFU综合性能提出了要求。

As a quantitative parameter for the analysis and evaluation of product carbon emissions,carbon footprint has become an important consideration for low-carbon industrial economy.The research on the Carbon footprint of fan filter unit(FFU)is of great significance because of its wide application inclean rooms and large proportion of energy consumption.In this paper,the carbon footprint of FFU during the full life cycle has been studied,which is based on the life cycle assessment method(LCA)and the"cradle-to-gate"model of the carbon footprint international standard PAS2050.Based on the prediction models of energy consumption,the carbon footprint of a FFU during the full life cycle is 5376.6kgCO_(2)e and 6873.7kgCO_(2)e.The proportion of carbon emissions during the operating phase accounts for more than 96%.Therefore,reducing the energy consumption in the operation phase is the main strategy to reduce the Carbon footprint of the FFU throughout its life cycle.Thisputs forward requirements for the use environment,HEPA/ULPA filter performance,and FFU performance.
