摘要：2020年提出的“碳达峰、碳中和”成为我国重大国家战略，建筑全过程碳排放占全国能源碳排放一半以上，如何进一步降低建筑碳排放是摆在建筑行业面前的一项重要课题，而建筑空调冷热源系统是影响建筑碳排放的重要环节，应能够顺应能源系统转型。对不同类型空调冷热源系统的碳排放强度进行了分析。区域电网的碳排放因子与冷热源系统的碳排放强度密切相关，对冷热源系统选择起决定作用。随着我国能源结构优化，区域电网的碳排放因子明显降低，冷热源系统电气化将是碳约束下主要的发展方向。

Abstract: In 2020, “carbon peaking and carbon neutrality” has become a major national strategy in China. The full life cycle carbon emissions of buildings account for more than half of the national energy carbon emissions. It is important to reduce building carbon emissions further for the building industry. The building air conditioning cold and heat source system is one of the substantial parts that affects building carbon emissions, and should have the conditions to adapt to the transformation of the energy system. This paper analyses the carbon emission intensity of different types of air conditioning cold and heat source systems. The carbon emission intensity of the cold and heat source systems is closely related to the carbon emission factor of the regional power grids.The level of the carbon emission factor of the regional power grids plays a decisive role in the selection of the cold and heat source system. With the optimization of energy structure in China, the carbon emission factor of regional power grids has been significantly reduced, and the electrification of cold and heat source systems is the main development direction under carbon constraint.
