| 摘要: |
| 变频空调器能效标准GB 21455—2013中以全年能源消耗效率APF来评价热泵型变频空调器，该指标没有按系统制冷剂种类进行区分，而是对所有制冷剂系统均以相同的系列值进行评价。因此，本文以理论选取和国标规定的两组时间曲线，对几种容量的变频空调器在相同环境影响（取TEWI指标），不同制冷剂种类情况下所产生的能效差异进行了分析研究。结果表明：在相同环境影响下，R290系统需要达到的能效水平明显低于R22、R410A系统，最大差值分别为0.57和0.59（2 HP机国标时间曲线的结果）。最后提出了能效标准应综合考虑制冷剂自身直接影响和系统间接影响，进行制冷剂分类评价的建议。 |

| Abstract: |
| China’s inverter air conditioner efficiency standard (GB21455—2013) adopts a single set of annual performance factor (APF) values to evaluate inverter heat-pump air conditioner charged with different types of refrigerants. Obviously, neglecting the refrigerant classification is a flaw in the standard. Thus, we obtained two types of running-time curves from meteorological statistics and standard data. Furthermore, on the basis of these curves, the APF of several inverter air conditioner with different refrigerants were analyzed in terms of the same environmental impact (the total equivalent warming impact (TEWI) was chosen). The results show that the APF values of the R290 equipment were relatively lower than those of R22 and R410A under the same environmental impact. According to the standard data results (air conditioner with 2 HP cooling-capacity), the APF differences between these refrigerants were up to 0.57 and 0.59, respectively. Finally, a refrigerant-classification evaluation in terms of the energy efficiency standards was performed. In addition to the indirect environmental influence on the equipment energy efficiency, the direct effect of refrigerants should also be considered. |
