美国通报节能方案：直接膨胀式专用室外空气系统除湿试验规程

编号：G/TBT/N/USA/1747

拟议规则制定通知和征求意见-美国能源部（DOE）提议建立“直接膨胀专用室外空气系统”（DX-DOAS或DX-DOASes）和“除湿直接膨胀专用室外空气系统”（DDX-DOAS或DDX-DOASes）的定义。DX DOASes是根据《能源政策和节约法案》（EPCA）修订的小型、大型和超大型商用空调和供暖设备的一个类别。此外，能源部还提议建立一个测试程序来测量DDX-DOASE的能源效率，该程序与DDX-DOASE相关行业共识测试标准的最新版本保持一致，并做了一些小的修改。最后，能源部提议增加辅助性定义、除湿和加热模式的能效指标以及管理公众陈述的规定，作为本规则制定的一部分。DOE欢迎公众就本文件范围内的任何主题（包括本提案中未明确提出的主题）提出书面意见，以及提交数据和其他相关信息。

最后征求意见日期：2021年9月7日

英文原文：

Notice of proposed rulemaking and request for comment - The U.S. Department of Energy (DOE) is proposing to establish definitions for "direct expansion-dedicated outdoor air systems" (DX- DOAS or DX-DOASes) and "dehumidifying direct expansion-dedicated outdoor air systems" (DDX-DOAS or DDX-DOASes). DX DOASes are a category of small, large, and very large commercial package air conditioning and heating equipment under the Energy Policy and Conservation Act (EPCA), as amended. In addition, DOE is proposing to establish a test procedure to measure the energy efficiency of DDX- DOASes, which aligns with the most recent version of the relevant industry consensus test standards for DDX-DOASes, with certain minor modifications. Lastly, DOE is proposing to add supporting definitions, energy efficiency metrics for dehumidification and heating modes, and provisions governing public representations as part of this rulemaking. DOE welcomes written comment from the public on any subject within the scope of this document (including topics not specifically raised in this proposal), as well as the submission of data and other relevant information.

Final date for comments: 7 September 2021
