摘要
随着风量的加大,对噪音系数在降噪型层流送风装置与传统型层流送风装置中的变化进行了研究,并对结果进行了对比分析;在不同的高度下检测了噪音系统在降噪型层流送风装置与传统型层流送风装置中的变化,并对结果进行了对比分析。实验结果表明:随着风量的加大,无论采用降噪型层流送风装置还是传统送风装置,噪音都随之加大,但是降噪型层流送风装置噪音增加的较为缓慢;随着检测高度越来越接近层流送风装置,噪音也随之加大,但是降噪型层流送风装置噪音增加的较为缓慢。
Two groups of experimental studies are taken under the same conditions. With the increas- ing amount of wind, noise factors in noise-canceling laminar flow air supply unit and in conventional lami- nar flow air supply unit were studied, and the results were compared and analyzed; the noise systems are tested at different heights for noise-canceling laminar flow air supply unit and conventional laminar flow air supply unit, and the results were analyzed. The comparative analysis shows, the noise will increase with the increasing amount of wind, regardless of selecting noise-canceling apparatus or traditional device, but the noise changes relatively slowly in the noise-canceling apparatus; and the noise will also increase with the detection height being closer to laminar flow air supply unit, but the noise changes relatively slowly in the noise-canceling apparatus.
