Abstract
Vibration and noise of scroll compressors of air conditioning units at the top floor of an office building in an Economic and Technological Development Zone are excessively high. The noise and vibration of the units have severe impact on the downstairs offices. Through the testing of these units, it is found that the central air conditioning unit and its pipes have no vibration isolators at all, which form an acoustic bridge between the equipment and the building and cause the spread of solid sound. Therefore, vibration isolation must be considered according to the characteristic of the solid sound spread to effectively reduce the pollution of low frequency noise. Due to the actual situation of the top floor, a double-stage vibration isolation system is considered. With the calculation, the vibration isolation system is designed, and then it is made and installed to the equipment. Finally, a good isolation effect is obtained. The average value of the noise level is reduced by 20 dB.关键词
