「英中对照」AABC发布第八版全系统平衡国家标准，更新暖通空调TAB指南

Their eighth edition updates industry guidance for testing, adjusting and balancing (TAB) HVAC systems for the first time since 2016.   October 20, 2026 该第八版自2016年以来首次更新了暖通空调（HVAC）系统测试、调整与平衡（TAB）的行业指南。   2026年10月20日

The Associated Air Balance Council (AABC) has published the eighth edition of its National Standards for Total System Balance, updating industry guidance for testing, adjusting and balancing (TAB) HVAC systems for the first time since 2016. 美国空气平衡委员会（Associated Air Balance Council，AABC）发布了其《全系统平衡国家标准》（National Standards for Total System Balance）第八版，这是自2016年以来首次更新暖通空调系统测试、调整与平衡（TAB）的行业指南。 

The American National Standards Institute (ANSI)-approved manual establishes minimum standards for total system balance, outlines TAB agency responsibilities and provides procedures intended to help design professionals achieve building system design intent. 这本经美国国家标准学会（ANSI）批准的手册确立了全系统平衡的最低标准，概述了TAB机构的职责，并提供了旨在帮助设计专业人员实现建筑系统设计意图的程序。 

“It's important to keep updating the standards because the industry is changing,” says Gaylon Richardson, AABC Standards Committee chairman and representative of Engineered Air Balance Co. Inc., in a press release shared with FacilitiesNet. “持续更新标准非常重要，因为行业在不断变化，”AABC标准委员会主席、Engineered Air Balance Co. Inc.代表Gaylon Richardson在与FacilitiesNet分享的新闻稿中表示。 

The eighth edition includes revisions to TAB reporting requirements, instrumentation and calibration standards, measurement tolerances and Pitot tube traverse procedures. It also adds guidance on fan laws, fan system equations and total leakage recommendations for air leakage testing. 第八版修订了TAB报告要求、仪器与校准标准、测量公差以及皮托管横截面测量程序。还新增了关于风机定律、风机系统方程以及空气泄漏测试总泄漏量建议的指南。

Other updates address testing procedures for constant- and variable-volume systems, energy recovery and temperature control systems, cooling towers, boiler plants, laboratories, kitchens and smoke control systems. The manual also includes new information on air flow-limiting devices (AFLDs) and pressure-independent control valves (PICVs). 其他更新涉及定风量与变风量系统、能量回收与温度控制系统、冷却塔、锅炉房、实验室、厨房和防排烟系统的测试程序。手册还新增了关于气流限制装置（AFLD）和压力无关型控制阀（PICV）的信息。 

The commissioning chapter has been rewritten to provide updated information on HVAC commissioning and commissioning plans. An entirely new chapter expands coverage of underfloor air distribution systems. 调试章节已重写，提供了有关暖通空调调试和调试计划的最新信息。全新的一章扩展了对地板下送风系统的介绍。 

Like the seventh edition, the latest version received approval from ANSI. According to AABC, the designation indicates that the standards development process meets ANSI requirements for openness, balance, consensus and due process. 与第七版一样，最新版本获得了ANSI的批准。据AABC称，该认定表明标准的制定过程符合ANSI对开放性、平衡性、共识和正当程序的要求。 

For facility managers, the updated guidance provides a reference for understanding TAB procedures and requirements when verifying HVAC system performance. Proper testing and balancing can help determine whether systems operate as intended and deliver the airflow and other conditions established during design. 对于设施经理而言，更新后的指南为在验证暖通空调系统性能时理解TAB程序和要求提供了参考。适当的测试与平衡有助于确定系统是否按预期运行，并提供设计阶段确定的气流和其他条件。 

The eighth edition of the National Standards for Total System Balance is available through AABC's website. 《全系统平衡国家标准》第八版可通过AABC官网获取。
