Abstract

Many range hoods on the market that use double-inlet Sirocco fans have significant shortcomings. This issue can be addressed by utilizing high-efficiency in-line duct fans. In this study, a commercially available canopy range hood was used as a reference unit. Two high-efficiency in-line duct fans, IL-Model(1) and IL-Model(2), were designed using professional fan design software. The target design specifications to compete with the internal Sirocco fan in the reference unit were around 22–24 CMM and 900–1100 Pa, respectively. These two fans were produced using 3D printing. Wind tunnel tests for IL-Model(1) and IL-Model(2) showed that the maximum air flow rate differed by less than 10% compared to CFD software analysis. When comparing the performance of the two fans to the Sirocco fan under the same 150 mm outlet diameter, the maximum air flow rate increased by 36.45% and 26.29%, the maximum static pressure increased by 33.04% and 38.30%, and the power consumption decreased from 23.9 W/CMM to 17.0 W/CMM and 20.0 W/CMM, respectively. This design effectively improves the performance and energy efficiency of range hoods.

高效直列风机在抽油烟机上的应用研究

市场上许多使用双进气Sirocco风机的抽油烟机都有明显的缺点。这个问题可以通过使用高效的管道风机来解决。在这项研究中，一个市售的冠状吸油烟机被用作参考单位。采用专业风机设计软件设计了IL-Model(1)和IL-Model(2)两台高效直列风管风机。与参考单元中的内部Sirocco风扇竞争的目标设计规格分别约为22-24 CMM和900-1100 Pa。这两个风扇是用3D打印制作的。IL-Model(1)和IL-Model(2)的风洞试验结果表明，与CFD软件分析相比，最大风量的差异小于10%。与Sirocco风机相比，在相同出口直径150mm的情况下，两种风机的最大风量分别提高了36.45%和26.29%，最大静压分别提高了33.04%和38.30%，功耗分别从23.9 W/CMM降低到17.0 W/CMM和20.0 W/CMM。这种设计有效地提高了抽油烟机的性能和能效。
