摘　　要：在保持R290空调器系统性能的前提下,为降低冷凝器中制冷剂积存量,建立冷凝器性能综合评价模型,对冷凝器不同支路数流程的结构参数进行优化研究。结果表明:管径减小使得制冷剂积存量下降、COP下降;管间距和翅片厚度增大以及翅片间距减小均使得制冷剂积存量下降、COP升高;对冷凝器的制冷剂积存量和系统COP进行多目标优化,得到最优设计结构参数为四支路流程,管径5.74 mm,管间距19.67mm,翅片间距1.43mm,翅片厚度0.092mm。本研究可为R290房间空调器减少制冷剂充注量提供参考。On the premise of maintaining the performance of R290 air conditioner system,in order to reduce the refrigerant storage in condenser,a comprehensive evaluation model of condenser performance is established,and the structural parameters of condenser with different branch number flow are optimized.The results show that the decrease of pipe diameter reduces refrigerant storage and COP;with the increase of tube spacing and fin thickness,as well as the decrease of fin spacing,the refrigerant storage decreases and COP increases.Multi-objective optimization of refrigerant storage of condenser and COP of system are carried out,and the optimal designed structure parameters are obtained as four-branch flow,tube diameter of 5.74 mm,tube spacing of 19.67 mm,fin spacing of 1.43 mm and fin thickness of 0.092 mm.This study provides reference for reducing refrigerant charge in R290 room air conditioner.
