摘要

该研究调查了基于盐水的金属氧化物纳米流体，以改善传热和制冰厂的 COP。这项研究的新颖之处在于使用表面活性剂和超声波制备稳定的氧化锌、氧化铜和氧化铝纳米流体，以改善采用蒸汽压缩制冷循环的制冰厂的性能。研究发现，使用这些纳米流体可显著提高制冰厂的 COP，其中颗粒体积浓度为 0.3% 的 Al2O3 纳米流体的改善幅度最大，达到 27%。实验还显示，在相同的浓度和温度下，压缩机功耗降低了 22%，这表明这些纳米流体在制冰厂的应用具有潜力。研究进一步表明，在 20 °C 的受控温度下，COP 的改善比 25 °C 时更为显著。

Experimental Investigation of Coefficient of Performance Enhancement (COP) in Ice Plant Using Brine-Based Metal Oxide Nanofluids

The research investigates brine-based metal oxide nanofluids to improve heat transfer and ice plant COP. The novelty of the study is in the use of stable nanofluids of ZnO, CuO, and Al2O3 prepared using surfactants and ultra-sonication to improve the performance of an ice plant working on the vapor compression refrigeration cycle. The study found that the COP of the ice plant was significantly enhanced using these nanofluids, with the greatest improvement of 27% observed for Al2O3 nanofluids at a particle volume concentration of 0.3%. The experiment also showed a reduction in compressor power consumption by 22% at the same concentration and temperature, indicating the potential use of these nanofluids in ice plant applications. The study further demonstrated that the COP improvement was more significant at a controlled temperature of 20 °C than at 25 °C.
