摘　　要：鉴于建筑用能全面电气化是实现零碳、低碳运行的最佳途径,根据供暖、炊事、生活热水现状调研分析零碳建筑电气化,分别通过居住建筑和公共建筑工程实例进行供暖、炊事、生活热水有无电气化的碳减排计算,进而研究零碳建筑电气化潜力,得出采用高效的空气源热泵制热可以有效降低建筑供暖的碳排放,电炊具比燃气炊具产生更多的碳排放,采用电热水器碳排放高于燃气热水器,但采用空气源热泵热水器、太阳能等方式能有效降低碳排放。同时,分析了“双碳”目标下零碳建筑电气化中存在的问题,如在超高温热泵、大容量高温热泵、超大容量热泵领域有待深入开展研发,能源价格体系改革等,最后提出零碳建筑电气化未来技术展望。In view of the fact that the comprehensive electrification of building energy is the best way to achieve zero-carbon and low-carbon operation,the electrification of zero-carbon buildings is analyzed according to the investigation of the current situation of heating,cooking and domestic hot water,and the carbon emission reduction of heating,cooking and domestic hot water is calculated through the examples of residential buildings and public buildings respectively,and then the electrification potential of zero-carbon buildings is studied.It is concluded that the use of efficient air source heat pump heating can effectively reduce the carbon emissions of building heating,electric cookers produce more carbon emissions than gas cookers,the use of electric water heater carbon emissions are higher than gas water heaters,but the use of air source heat pump water heater,solar energy and other ways can effectively reduce carbon emissions.At the same time,the paper analyzes the problems existing in the electrification of zero carbon buildings under the goal of"dual carbon",such as the need for in-depth research and development in the field of ultra-high temperature heat pump,large capacity high temperature heat pump,super capacity heat pump,energy price system reform,and finally puts forward the future technology outlook of zero carbon building electrification.
