R22和R410A在水平微肋管内冷凝性能的实验研究

Experimental study on condensation heat transfer performance of horizontal micro-fin tube with R22 and R410A

建立无润滑油的实验台,以R22和R410A为工质,测试微肋管的传热系数,并将其结果进行比较。从实验数据可以得出,R22传热系数最高,R410A的压降值最小,该管较好地验证了实验的正确性,同时说明了实验管的高效性。

Establishes the lubricating-oilless laboratory bench to test and compare the condensation heat transfer performance of the Micro-fin tube using R22 and R410A. According to the experimental data, R22 has the maximum heat transfer coefficient, R410A the minimum pressure drop. Experiment＇s accuracy has good confirmation by tube and simultaneously indicates that the tube＇s highly effective.
