摘要

制冷剂质量流量为1 g/s以下的低质量流量下分液孔的大小和位置对分液冷凝器的性能有重要影响。对R600a在5种不同微通道分液冷凝器内的传热性能和压降进行了实验研究，对不同制冷剂质量流量、入口空气温度和风量、冷凝压力下5种分液冷凝器的传热性能和压降特性进行分析。根据实验结果，第二隔板开孔分液冷凝器传热性能优于第三隔板开孔分液冷凝器。制冷剂质量流量越大，分液冷凝器制冷剂侧压降减小越明显。制冷剂质量流量为0.60、0.40 g/s时，第二隔板开孔分液冷凝器制冷剂侧压降较未分液冷凝器分别降低21.28%、17.29%。利用综合评价因子

对比了不同开孔直径分液冷凝器的性能，分液孔径为1.2 mm的分液冷凝器平均

值为1.58，在所有分液冷凝器中最高，综合性能最好。

Abstract

The size and location of the separating holes at low mass flow rates （<1 g/s） have a significant impact on the performance of condensers with liquid separation. The heat transfer performance and pressure drop of R600a in five microchannel condensers with liquid separation were studied experimentally. Additionally， the heat transfer performance and pressure drop characteristics of the five liquid separation condensers under different refrigerant mass flows， inlet air temperatures and velocities， and condensing pressures were analyzed. According to the experimental results， the heat-exchange performance of the condenser with liquid separation orifice at the second baffle was better than that at the third baffle. As the mass flow rate of the refrigerant increased， the refrigerant-side pressure drop in the liquid separation condenser decreased significantly. When the refrigerant mass flow rate was 0.60 g/s and 0.40 g/s， the refrigerant-side pressure drop of the condenser with liquid separation orifice on the second baffle was 21.28% and 17.29% lower， respectively， than that of the baseline condenser without liquid separation. The performances of the liquid separation condensers with different orifice diameters were compared using the comprehensive evaluation factor PEF. The average PEF value of the liquid separation condenser with an orifice size of 1.2 mm was 1.58. This was the highest among all the liquid separation condensers and yielded the best comprehensive performance.
