|
Abstract:
本文制备了一种超亲水涂层和超疏水涂层，探索了应用在窗式空调的冷凝器翅片上的效果。本次研究通过硝酸银溶液、全氟癸基硫醇溶液(HDFT)以及11-巯基十一烷酸溶液(MUD)等材料在铜片上制备了超亲水涂层以及超疏水涂层。在不同的冷却温度及环境湿度下对各种涂层的冷凝效果进行了测试及研究。实验结果显示，在7℃冷却水温度，95%相对湿度的工况下，超疏水涂层的冷凝速度可达45.9 g/m2min，比铜片的冷凝速度提高了38.2%，证明了超亲水涂层和超疏水涂层对窗式空调的冷凝器有着积极的影响。
In this study, a superhydrophilic coating surface and a superhydrophobic coating surface were investigated. The effect of the coating surfaces on the fins of the condenser of a window air conditioner was discussed. The superhydrophilic surface and the superhydrophobic surface were prepared with the silver nitrate solution, 11-mercaptoundecan-1-undecano (MUD) solution and heptadecafluoro-1-decanethiol (HDFT) solution. A testing about the condensation rate of the surfaces was performed under different cooling temperature and relative humidity. The results showed that a condensation rate of 45.9 g/m2min of the superhydrophobic composite coating surface was achieved, which was 38.2% higher than that of the copper surface under the operating condition of a surface temperature of 7？C and a relative humidity of 95%. It showed that the superhydrophilic and the superhydrophobic coating surfaces had a positive influence on the condenser of the window air conditioner.
