【摘要】 随着美国AHRI 210/240能效升级，变频空调的制热季节能效HSPF2的计算方法更侧重于中低温工况。通过对季节能效的计算方法和实验数据分析发现，在相同配置下，新能效HSPF2相比于旧能效HSPF明显下降，气候分区IV区对应的HSPF2_IV平均下降8.0%,V区对应的HSPF2_V平均下降17.2%；中低温制热工况（H2_V、H3₂、H4₂）下的COP对HSPF2的影响比重较大，产品设计时可以考虑增加压缩机排量、选择高效压缩机和电机、优化换热器结构等手段提升季节能效。关键词：更多还原

【Abstract】 With the energy efficiency upgrade of AHRI 210/240 in the United States,the calculation method of heating seasonal performance factor （HSPF2） of variable frequency air conditioners focuses more on the medium and low temperature conditions.Through the analysis on the calculation method of HSPF2 and experimental data,it is found that under the same configuration,the HSPF2 is significantly lower compared with the original heating seasonal performance factor （HSPF）.The HSPF2_IV corresponding to the climate zone IV decreases by 8.0%on average,and the HSPF2_V corresponding to the zone V decreases by 17.2%on average.The COP under medium and low temperature conditions （H2_V,H3₂,H4₂） has a large proportion of influence on HSPF2.In product design,increasing compressor capacity,using efficient compressor and motor,optimizing heat exchanger structure and other solutions can be considered to improve the seasonal performance factor.更多还原
