摘　　要：为有效提升变频空调器全年运行能效APF,本文对APF的非连续计算式编程,求解可实现的最高能效,以及对应5个标准测试工况下能力Φi和功率Pi的最佳调试值。通过敏感性分析求解可调试参数对APF的影响权重,以寻求提升APF的最优调试路径。结果发现:现有将能力Φi与功率P_i当作独立变量分析APF的方法,无法真实揭示APF的变化规律;结合某35样机实验数据获得Pi-Φi函数关系后重新计算,最高可实现能效APF为5.243;中间制热为最大影响工况,权重高达44.97%,APF与中间制冷、中间制热能力为负相关;在国标规定范围内,最大幅度降低中间制热能力,是提升APF最有效的技术途径之一。To improve the annual energy efficiency coefficient APF of variable frequency air conditioners effectively,calculation formula of the APF was analyzed to seek the highest efficiency,as well as the corresponding optimal parameters capacity Φi and power Consumption P_i.Sensitivity analysis was conducted to find the optimal technical methods to promote APF.After fitting experiment data of Pi-Φi,the real variation rules of APF and impact weights of Pi,Φi to APF were revealed.Taking a 3500 W prototype as an example,it is found that the highest APF is 5.243;Intermediate heating is the most impact factor,with the weight up to 44.97%;APF is negatively correlated with intermediate refrigeration and intermediate heating capacity;The maximum reduction of intermediate heating capacity is one of the most effective ways to improve APF.
