摘　　要：本文采用仿真与实验结合的方式,对翅片铝材料导热系数与空调器整机全年能源消耗效率(APF)的关系进行了理论分析。计算了翅片导热系数对换热器传热单元换热量影响规律,推导了空调器换热器空气侧换热系数的关联式,并给出导热系数与空调器整机APF的关系。计算结果表明:将翅片所使用铝材料从铝合金3003替换为高导热性能铝材料6Z07,翅片的导热系数从190 W/(m·K)增加到210 W/(m·K),测试样机的翅片单元的换热量提升5.5%;样机的APF从3.92增加到4.02,提升幅度为2.55%。The relationship between thermal conductivity of aluminum fin material and annual performance factor(APF)of air conditioner is analyzed by simulation and experiment in this paper.The influence law of fin thermal conductivity on heat transfer unit of heat exchanger is calculated,a new air side heat transfer coefficient correlation is derived,and the relationship between thermal conductivity and APF of air conditioner is given.The results show that when the thermal conductivity increases from 190 W/(m·K)to 210 W/(m·K),the heat transfer increases by 5.5%.For the test prototype used in this paper,the APF of the prototype increases from 3.92 to 4.02(increases by 2.55%)with the replacement of its fin material.
