热激活建筑系统研究进展

 基于控制围护结构传热温差而提出的热激活建筑系统（TABS），可利用注入低品位能源形成热屏障的方式降低建筑负荷，是实现建筑能碳双控目标的重要措施。提出了TABS分类与评价方法，从热工性能、集成设计、可持续性和应用潜力等角度对空气基、液体基和固体基TABS进行了梳理与对比分析。现有研究表明：集成空气基TABS的围护结构当量传热系数小于0.3 W/（m²·K），渗透型还具备热回收与空气净化的双重效果；液体基TABS在一体化集成和热激活效能方面更具优势，围护结构当量传热系数可降至-3.6 W/（m²·K）；固体基TABS则具有无循环工质、无运动部件和无噪音等优点，围护结构当量传热系数可降至-3.0 W/（m²·K），但未来需要解决其立面集成和热电模块商业化等问题。

Research progress on thermo-activated building system

The thermo-activated building system (TABS), which is considered to be an important measure to achieve the goal of dual control of energy and carbon in buildings, can reduce the building load by injecting low-grade energy to form a thermal barrier. The proposed system is based on controlling the heat transfer temperature difference of the envelope. This paper presents the classification and evaluation methods of TABS, and systematically compares and analyzes air-based, liquid-based and solidbased TABS from the perspectives of thermal performance, integrated design, sustainability and application potential. Existing studies show that the equivalent heat transfer coefficient of the envelope integrated with air-based TABS is less than 0.3 W/(m²· K). Permeable air-based TABS also has the dual effect of heat recovery and air purification; Liquid-based TABS is more advantageous in terms of integration and operational energy efficiency, with an equivalent heat transfer coefficient of the envelope down to -3.6 W/(m²·K); Solid-based TABS has the advantages of no working fluid, no moving parts and no noise, and its envelope equivalent heat transfer coefficient can be reduced to -3.0 W/(m²·K). However, issues such as its façade integration and commercialization of thermoelectric modules need to be addressed in the future.
