摘　　要：本文通过实验研究了制冷剂管路合并与否对冷凝器换热性能的影响,利用coil-designer软件模拟分析了制冷剂管路不同位置合并对冷凝器性能的影响,从而找出制冷剂管路最佳合并位置。结果表明,合并管路结构的冷凝器换热性能优于不合并管路结构的冷凝器,且随着制冷剂管路合并位置向下,换热量先增大后减小,存在一个最佳合并位置,压降逐渐减小,综合考虑换热量、压降大小,在干度为0.1~0.2位置对制冷剂管路进行合并换热效果最佳。The effects of the combined position of refrigerant pipelines on the heat transfer performance of the condenser were analyzed by experiments and simulations.The effects of refrigerant pipelines on the heat transfer performance of the condenser were studied experimentally,and the influence of different positions of refrigerant pipelines on the performance of the condenser was simulated by the coil-designer,thereby finding the best combined position of the refrigerant pipelines.The results show that the heat transfer performance of the condenser with combined pipelines is better than that of the condenser without the combined pipelines.As the combination position is downward,the heat exchange increases first and then decreases,there is an optimal merge position,and the pressure drop is gradually reduced.Considering the heat exchange and pressure drop,the best combination of refrigerant pipelines is at the quality of vapor-liquid mixture of 0.1~0.2.
