摘要
以水和结晶醋酸钠作换热和蓄热介质,对内纵翅片套管相变蓄热器的充、放热特性进行了实验。实验结果表明:水流速增加,充、放热速度增加;进口水温升高,充热速度越快,放热越慢。此外,综合实验数据得到了两个有关蓄热器性能的关系式。
This paper presents the experimental results of charge and discharge perfor-mance in phase change accumulator with inner fined casing-tube. This experiment was carried outusing water and Na2CH3COO·3H2O as heat transfer and accumulate media with the various volocityand inlet temperature of water.The results show that the imcrease of water volocity causes the in-crease of heat charge and dlseharge volocity;the higher inlet temperature of water is the faster theheat charge , but the slower the discharge. Two general correlations for heat charge and discharge areobtained according to the experimental data.
