空调机组并联运行时噪声的影响及改善措施分析
Influence and improving measures of noise for air conditioning units in parallel
摘要：
测试了空调机组不同运行台数下的噪声，分析了影响机组噪声叠加的因素，指出机组台数的增多不会对整体噪声产生较大影响。根据实测数据，提出了改善措施。

Abstract：
Measures the noise of air conditioning units with different operating numbers, analyses the influencing factors of the units’ noise superposition, and points out that the increase of operating numbers of units would not cause larger effect on the noise of the whole units. Puts forward some improving measures based on the measured data.
