【摘要】：在对内融冰式蓄冰槽内不同水层的水进行过冷度测试中发现上层水的过冷度较大。为了降低水的过冷度和冷水机组能耗,通过实验的方法对不同的成核添加剂进行筛选测试,结果显示纳米氧化铜不但在降低过冷度方面效果显著,而且提高了蓄冰效率。最后获取了一定质量分散剂下最佳纳米氧化铜的质量分数,即在-5℃的制冰温度下,质量分数为0.10%的氧化铜悬浊液为最佳配比。在实验过程中发现水的过冷度还与换热介质的传热温差有关,温差越大过冷度越小。
[Abstract]:It is found that the supercooling degree of the upper layer water is higher than that of the inner melt ice storage tank by measuring the subcooling degree of the water in different water layers in the inner melting ice storage tank. In order to reduce the undercooling degree of water and the energy consumption of chillers, different nucleation additives were screened and tested by experimental method. The results show that nano-copper oxide not only reduces the undercooling degree, but also improves the ice storage efficiency. Finally, the optimum mass fraction of nano-copper oxide under certain mass dispersant was obtained, that is, the optimum proportion of copper oxide suspension was 0.10% at -5 鈩，
