| 新型单、双排平行流冷凝器应用于冷柜制冷系统中，并与原管片式冷凝器冷柜制冷系统进行对比实验分析。结果表明，应用单、双排平行流和管片式冷凝器的冷柜制冷系统分别在充灌量为550g、650g和800g时，周期内压缩机平均功耗最小，其中双排平行流冷凝器周期内压缩机平均功耗最小，单排平行流和管片式冷凝器相当。平行流冷凝器的空气侧换热性能明显优于管片式冷凝器。实验所用单、双排平行流冷凝器仅为管片式冷凝器换热体积的四分之一和二分之一，将平行流冷凝器应用于冷柜系统中将有利于解决冷柜冷凝器在恶劣环境下运行换热量不足的问题和降低成本费用。 |

| Abstract: |
| Single and double row parallel-flow condensers had been used in the refrigerated display cabinet. This system was compared to the refrigerator system which used fin-and-tube condenser. This study show that the compressor average power consumption in a cycle was minimum when refrigerant was charged 550g, 650g and 800g respectively in the refrigerator systems which used single, double row parallel-flow and fin-and-tube condensers. The system with double row parallel-flow condenser consumed the least power among the three systems, and the system with single row parallel-flow condenser was almost the same with the system with fin-and-tube condenser. In the air side, parallel-flow condensers’ performance was better than the fin-and-tube condenser. The single and double row parallel-flow condensers only have a quarter and a half volume of the fin-and-tube condenser in the experiment, which indicates that parallel-flow condenser will be a good solution for the insufficient heat exchange capacity in the harsh environment and reduction of the cost when applied in refrigerator. |
