摘要： 介绍了HVAC系统碳足迹的分析方法，提出了评价系统对环境影响程度的两个指标：碳排量和单位输出能量的碳排量。前者用作同一区域的多种设计方案的评价指标，后者用作任何系统的环境影响评价指标。这两个指标可作为规划阶段不同系统设计方案的环境影响评价指标，也可作为对运行系统碳排量监测的理论依据。另外，提出了设定HVAC系统的基准碳排量的思想。 关键词： 碳足迹 碳排量 环境评价指标 HVAC系统 基准碳排量 Carbon footprint analysis and environmental evaluation indices of HVAC system By Fan Ying★ and Long Weiding Abstract Presents the analysis method of carbon footprint of HVAC system, and puts forward two indices for assessing the impact of HVAC system in operation on environment: carbon emissions and carbon emissions per output energy. The former is for comparing various HVAC system design schemes for the same space, and the latter is for any systems. The both can be used as not only the environmental evaluation indices for various HVAC system design schemes, but also as the theory basis for carbon emission monitoring of the operational systems. In addition, suggests building up baseline carbon emissions of HVAC system.
