摘　　要：针对GB 21455—2019《房间空气调节器能效限定值及能源效率等级》与GB 19576—2019《单元式空气调节机能效限定值及能效等级》两个规范在全年能源消耗效率(APF)和制冷季节能源消耗效率(SEER)两种能效等级指标值要求的不同,从两者各自的适用范围、能效等级数值、引用标准及其适用范围等方面,进行了不同维度的对比分析。为了便于设计人员选择设计依据及相关规范,讨论细化了两者各自的具体用途和使用场所,可供读者参考。如遇两者有交集的情况,建议按较严格的要求取值,避免影响设备招采和项目验收。为确保项目能正确将设计意图落地实施,提出设计人员除设计工作之外,还需配合的其他工作内容。In response to the differences in the requirements for Annual Performance Factor(APF)and Seasonal Energy Efficiency Ratio(SEER)energy efficiency level indicators in the GB 21455-2019"Minimum Allowable Values of the Energy Efficiency and Energy Efficiency Grades for Room Air Conditioners"and the GB 19576-2019"Minimum Allowable Values of Energy Eficiency and Energy Efficiency Grades for Unitary Air Conditioners",a comparative analysis is conducted on the above two specifications from the aspects of scope of application,energy efficiency grade,cited standards,and cited standards,discuss and refine their specific purposes and usage locations.In order to facilitate designers to choose the above two design criteria and related specifications,the specific purposes and usage locations of each have been discussed and refined,which can be used as a reference for readers.If there is an intersection between the two,it is recommended to follow stricter requirements to avoid affecting equipment procurement and project acceptance.To ensure that the project can correctly implement the design intent,it is proposed that designers should cooperate with other work tasks in addition to design work.
