optimization of fin surface wettability for promoting the Dust Removal in heat exchangers under frosting defrosting conditions
International Journal of Refrigeration-revue Internationale Du Froid, 2020Co-Authors: Dawei Zhuang, Yifei Yang, Guoliang Ding, Feilong ZhanAbstract:Abstract Dust Removal by frosting-defrosting is a novel way to keep the cleanness of heat exchangers of air conditioners during long-term operation, and the effect depends on the fin surface wettability. The purpose of this study is to obtain the optimal choice of fin surface wettability for Dust Removal by testing Dust Removal characteristics on various surfaces, covering bare aluminum surface, bare copper surface, hydrophilic surface and hydrophobic surface. The temperatures of the air dry-bulb, air wet-bulb, the frosting surface and the defrosting surface in the experiments are 7 °C, 6 °C, -15 °C and 5 °C, respectively. The results show that, the hydrophobic surface has the best Dust Removal effectiveness; the remnant Dust rates on the surfaces are 28.4%, 28.0%, 8.69% and 0.54% for bare aluminum plate, bare copper plate, hydrophilic copper plate and hydrophobic copper plate, respectively; the Dust Removal time on hydrophobic surface is much less than that on the other ones.

Effect of surface wettability of fins on Dust Removal by condensate water
International Journal of Heat and Mass Transfer, 2019Co-Authors: Yifei Yang, Dawei Zhuang, Guoliang DingAbstract:Abstract Using the condensate water to remove the Dust on fins is an economic way to maintain the heat transfer performance of a fin-and-tube evaporator, and the Dust Removal performance depends on the fin surface wettability. The purpose of this paper is to experimentally investigate the effect of surface wettability on Dust Removal by condensate water, covering the surfaces of hydrophilic coating, hydrophobic coating, superhydrophobic coating, and uncoated copper. The experimental conditions cover the inlet air temperature of 27 °C, the inlet air relative humidity of 50%, the inlet air velocity of 2 m s−1, the Dust concentration of 10.8 g m−3, the Dust deposition time of 30 min, and the sample surface temperature of 12 °C. The results show that, the superhydrophobic surface has the best Dust Removal performance, and the remnant Dust weight on superhydrophobic surface is 69.9% lower than that on the uncoated copper surface, 61.1% lower than that on the hydrophilic surface and 3.59% lower than that on the hydrophobic surface.

Further Study of Electric Dust Removal with Transparent Fork Electrodes
American Journal of Analytical Chemistry, 2015Co-Authors: Tianlan Yin, Dongdong FengAbstract:This study is a continuation of our previous work. In this experiment, transparent tin-doped indium oxide (ITO) fork electrodes with different width and spacing were coated on the glass substrates. The used Dust particle size was smaller than 180 mesh. The effects of the electrode width, the electrode spacing, voltage, frequency, waveform, and the duty ratio on the Dust Removal efficiency were studied. The obtained optimum conditions of Dust Removal were as follows: voltage was 1500 V, frequency was 15 Hz, square wave, 10% duty ratio, the electrode width was 0.5 mm, electrodes spacing was 1.3 mm. Our previous experimental results show that the Dust Removal efficiency would be up to 95%. But in this experiment, under the optimum conditions, the Dust Removal efficiency could be up to 99%.
