摘　　要：对非共沸混合制冷剂R407C用于家用空调器的性能进行了实验研究,给出了空调器的毛细管最佳长度和制冷剂最佳充注量,并对其出现的问题进行了理论分析.结果表明:随着充注量的增加,系统制冷功率和COP都是先增加后减小的;在毛细管直径为1.5 mm,长度为600 mm条件下,制冷剂充注量达到约630g时,制冷功率和性能系数COP均达到峰值,其值分别为2460.4W和2.474;R407C充注量为630g条件下,毛细管长约为600mm时制冷功率达到一个最大值2460W,毛细管长度为550mm时,系统性能系数COP达到最大值2.48.An experimental analysis was carried out on effects of capillary length and refrigerant charge amount on the perform-ances of a domestic air - conditioner using R407C as refrigerant. The results showed that the cooling capacity and COP of the system are increased with the increase of charge amount at the first stage and then decreased ; on conditions of the capillary di-ameter is of 1.5 mm with a length of 600 mm, the refrigerating capacity and the COP reached the peak with values of 2460.4W and 2.474, respectively, when the refrigerant charge amount is about 630g; on conditions of charge amount is 630g, the cool-ing capacity reaches a maximum value of 2460W when the capillary length of about 600mm and the COP reaches a maximum value of 2.48 when the capillary length is 550mm.
