      擬議規則制定通知和征求意見-美國能源部(DOE)提議建立“直接膨脹專用室外空氣系統”(DX-DOAS或DX-DOASes)和“除濕直接膨脹專用室外空氣系統”(DDX-DOAS或DDX-DOASes)的定義。DX DOASes是根據《能源政策和節約法案》(EPCA)修訂的小型、大型和超大型商用空調和供暖設備的一個類別。此外,能源部還提議建立一個測試程序來測量DDX-DOASE的能源效率,該程序與DDX-DOASE相關行業共識測試標準的最新版本保持一致,并做了一些小的修改。最后,能源部提議增加輔助性定義、除濕和加熱模式的能效指標以及管理公眾陳述的規定,作為本規則制定的一部分。DOE歡迎公眾就本文件范圍內的任何主題(包括本提案中未明確提出的主題)提出書面意見,以及提交數據和其他相關信息。



      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
