摘要
对该候车厅一体化空调射流机组在不同台次运行条件下的噪声进行了测试,模拟预测了候车厅的声环境,发现机组送风口的噪声偏大,候车厅局部声环境达不到要求。对机组提出了改进建议,并对改进后的候车厅声环境重新进行了模拟,局部噪声偏大的现象完全消除。
Measures the noise of the integrated air conditioning jet units in the waiting hall in the condition of different operating unit numbers.Simulating the acoustic environment of the waiting hall,finds that the noise of air supply outlets is large and the indoor local acoustic environment does not meet the requirement of the related code.Puts forward some improving suggestions.The simulation of the improved operating condition proves that the over high noise in local acoustic environment has been eliminated.
