To identify the key stages and main influencing factors of carbon emissions during the lifecycle of low ambient temperature air source heat pump (chiller) units for industrial and commercial use, and to guide low-carbon design of the units, based on the theory of life cycle assessment, the main greenhouse gas emissions of low ambient temperature air source heat pump (chiller) units for industrial and commercial use were calculated and sensitivity analyzed in five stages:raw material acquisition, processing and assembly, operation, transportation, recovery and disposal. The results show that the main contributions of greenhouse gas emissions during the life cycle of the unit come from the electricity consumption and refrigerant emissions during the operating stage, accounting for over 98%, while other stages can be basically ignored. After replacing R410A with R454B, which has a lower global warming potential (GWP), the total greenhouse gas emissions decreased by 15.14%. When the energy efficiency level of the unit is increased from level 2 to level 1, the total greenhouse gas emissions are reduced by 3.03%. In addition, the change in energy structure has resulted in a reduction of over 6.77% in total greenhouse gas emissions. Therefore, the carbon reduction in the life cycle of low ambient temperature air source heat pump (chiller) units for industrial and commercial use should focus on the operating stage. Using refrigerants with low GWP, improving energy efficiency, and increasing the proportion of new energy in the national energy structure are important ways to reduce carbon emissions throughout the life cycle of the unit.

为辨识工商业用低环境温度空气源热泵（冷水）机组碳足迹分析的关键阶段和主要影响因素，指导机组低碳设计，基于生命周期评价理论，对工商业用低环境温度空气源热泵（冷水）机组的原材料获取、加工装配、运行、运输、回收与处置5个阶段的主要碳排放分别进行了计算及敏感度分析。结果显示，在机组的整个生命周期中，碳排放的主要来源是运行阶段的电力消耗以及制冷剂的泄漏，占比超98%，其他阶段基本可以忽略；机组使用更低全球变暖潜值（GWP）的R454B制冷剂替换R410A制冷剂时，生命周期总碳排放量降低15.14%；机组的能效水平由2级提升为1级时，生命周期总碳排放量降低2.56%；能源结构变化带来的生命周期总碳排放量降低超过6.77%。工商业用低环境温度空气源热泵（冷水）机组生命周期的减碳应重点关注运行阶段，采用更低GWP的制冷剂、提升机组能效水平及国家能源结构中新能源比例是机组生命周期减碳的重要途径。
