全寿命周期碳排放视角下数字技术在暖通空调设计运维中的应用
Application of digital technologies to design and operation of HVAC system from perspective of life cycle carbon emissions
摘要：
以系统仿真、物联网和人工智能等为代表的数字技术正成为支撑建筑全寿命周期碳排放（LCCO2）管理的关键手段。探讨了数字技术在暖通空调节能设计与低碳运维中的应用和发展，认为方案设计不应仅停留在设计工况下负荷的静态评估，而应通过系统建模与仿真模拟不同控制策略下设备运行状态的动态变化对功耗的影响，同时注重碳足迹核算数字化工具的使用。PLM（产品全寿命周期管理）平台有助于建立暖通空调系统的数字孪生模型，将系统调适过程前置以降低试错成本，并促进暖通和自动控制专业的协同设计，加速“双碳”目标在暖通空调领域的落地。
Abstract：
Digital technology, represented by system simulation, internet of things and artificial intelligence, is becoming the key means to support the management of building life cycle carbon emissions (LCCO2). This paper discusses the application and development of digital technology in HVAC energy-saving design and low-carbon operation and maintenance, and believes that the scheme design should not only stay in the static assessment of load under design conditions, but also simulate the impact of dynamic changes of equipment operation status on power consumption under different control strategies through system modeling and simulation, and pay attention to the use of digital tools for carbon footprint accounting. The PLM (product life cycle management) platform in building industry could serve as a convenient tool to practice digital twin technology for HVAC system. Specifically, PLM has huge potential to lower trial-and-error cost by putting system commissioning before construction phase, and the collaborative design of HVAC and auto control system could also be made possible based on same model and data source, accelerating the implementation of the “dual carbon” goal in the HVAC field.
