Influence analysis of noise from integrated air conditioning jet units in Chengdu East Station Waiting Hall

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.
