摘要:
试验研究了超声功率对冷壁面冻结液滴脱除效果的影响,分析了不同超声功率对不同尺寸以及不同冻结时间冻结液滴的脱除能力.试验结果表明,超声振荡可以有效脱除冷表面冻结液滴,且随着超声输入功率从100 W增加到1 000 W,冷壁面冻结液滴脱除概率逐渐增加;冻结液滴粒径越大,超声功率对冻结液滴的脱除效果越显著;冻结时间越长,达到相同脱除概率所需的超声功率越大.通过调整超声功率可使冷表面冻结液滴的脱除概率达到70%.试验结果为超声波除霜功率参数配置提供了依据.
Abstract:
The effects of ultrasonic power on the removal of frozen water droplets from cold surface were experimentally studied and the abilities of different ultrasonic power in removing frozen water droplets with different sizes and freezing times were analyzed. The experimental results indicate that the frozen water droplets on cold surface can be effectively removed by ultrasonic oscillation, and the removal probabilities of frozen droplet gradually increase with the increase of the ultrasonic input power from 100 to 1 000 W. The frozen water droplets with bigger size can be more effectively removed under the same ultrasonic input power. The longer the freezing time, the bigger the ultrasonic input power is needed for the same removal probability. The removal probability of frozen water droplet can be achieved 70% by properly adjusting the ultrasonic input power. The results provide a basis for ultrasonic power parameter configuration of ultrasonic defrosting.
