Implementation path and case study of zero-carbon operation of a super high-rise building in hot summer and warm winter zone
摘要：
实现超高层建筑节能低碳发展对建筑领域兼顾高质量发展与“双碳”目标具有突出的示范意义。本文以我国夏热冬暖地区某超高层建筑为例,开展了深入的能耗分析与能源系统运行诊断。研究表明,超高层建筑空调系统形式复杂,是节能降碳的关键所在。结合温湿度独立控制、大温差冷水系统、多级串联冷水机组、过渡季新风免费制冷等技术,有效降低了空调系统能耗,但仍存在节能降碳空间。随后结合仿真模拟,探究了不同节能降碳技术的实施效果,进而围绕降低供冷需求、提升能源转化效率、增加可再生能源利用率等方面构建了零碳运行实施路径,为同类型项目提供参考案例与技术支持。
Abstract：
The realization of energy-saving and low-carbon development of super high-rise buildings has outstanding demonstration significance for high-quality development and “dual carbon” goals in the building field.Taking a super high-rise building in hot summer and warm winter zone of China as an example,this paper conducts detailed energy consumption analysis and energy system performance diagnosis.The research shows that the form of the air conditioning system in super high-rise buildings is complex,which is the key to energy conservation and carbon reduction.Combining technologies such as temperature and humidity independent control,large temperature difference chilled water system,multi-stage series chillers,and free cooling with outdoor air in the transitional season,the energy consumption of the air conditioning system is effectively reduced,but there is still space for energy conservation and carbon reduction.Subsequently,combined with simulation,the implementation effects of different energy conservation and carbon reduction technologies are explored,and then a zero-carbon operation implementation path is constructed around reducing cooling demand,improving energy efficiency,and increasing the utilization rate of renewable energy,providing reference cases and technical support for similar projects.
