基于生命周期评价理论,将集中式空调系统生命周期划分为生产、运输安装、运行、拆除及回收4个阶段,并建立了集中式空调系统生命周期各阶段及总的CO2排放量核算模型,提出了以集中式空调系统每年单位制冷量的CO2排放量作为不同类型集中式空调系统生命周期碳排放量对比指标的方法。结合工程实例,对比3种集中式空调系统生命周期CO2排放情况,并分析空调系统使用寿命对生命周期碳排放量的影响。
Based on life cycle assessment theory, the life cycle of the centralized air-conditioning system is divided into four stages of production, transportation, installation, operation, dismantling and recycling, and the life cycle phases of the centralized air-conditioning system and the total CO2 emission accounting model are established. Taking the annual CO2 emissions per unit of capacity of centralized air-conditioning systems as a measure of carbon emissions over the life cycle of different types of centralized air-conditioning systems, Combining with the engineering examples, the life cycle CO2 emissions of the three types of centralized air conditioning systems were compared and the life cycle carbon emissions of the air conditioning system were analyzed.
