摘要空调能效标准作为产品节能控制的有效手段，已被各国普遍采用，但因地理、经济水平等客观因素导致各国能效标准水平不一而足。针对欧盟能效标准EN14825:2016与中国标准GB/T7725—2004中规定的能效测试要求和计算方法的差异进行了理论分析，并通过实验验证了2种标准的能效值差异。结果表明：同一机型在欧盟标准和中国标准2种测试计算方法下，制冷、制热季节能效值欧盟标准分别比中国标准约高62%,20%；而能效等级判定中欧盟标准却比中国标准略低。

Abstract As an effective means of energy saving control of products,air conditioning energy efficiency standards have been widely adopted in many countries,but the level of energy efficiency
周文雍standards varies due to objective factors such as geographic and economic.Performs a theoretical analysis of
the differences in energy efficiency test requirements and calculation methods between the EU energy
efficiency standard EN14825：2016and the Chinese standard GB/T7725-2004,and verifies them through
坡道起步>朝代的顺序experiments.The results show that the SEER and SCOP of the EU standard is62%and20%higher than
that of the Chinese standard respectively,and the energy efficiency level rated by the EU standard is lower
than that rated by the Chinese standard for the same air conditioner.

o引言
目前，国内空调能效测试要求及计算方法依据标准GB/T7725—2004《房间空气调节器》⑷（以下简称GB/T7725-2004），变频空调器能效等级划分采用能效标准GB21455—2013«转速可控型房间空气调节器能效限定值及能效等级》⑵（以下简称GB21455—2013）。出口欧盟的变频空调器采用欧盟标准（以下简称欧标）草案EN14825：2016Air conditioners,liquid chilling packages and heat pumps,with electrically driven compressor,for space heating and cooling一Testing and rating at part load conditions and calculation of seasonal performance^（以下简称EN14825：2016）o齐云等人以流程图的形式介绍了欧标草案中所规定的空气冷却型空调器的制冷季节能效比SEER和制热季节性能系数SCOP的计算方法⑷。汪东明等人认为欧盟各温区的单点能效对于SEER的权重由各温度发生时间决定，
