集中布置的多联空调机房噪声传播规律与消声量研究

Study on the Noise Transmission Law and Noise Elimination of the Centralized Air Conditioning Room

本文根据噪声的传播原理得出了集中布置的多联室外机房噪声的衰减与叠加规律,研究了拟建建筑物空调机房不同层数、与住宅不同距离的情况下空调机房噪声的传播规律,得出了机房对面住宅在达到《声环境质量标准》下,不同距离与不同层数的空调机房所需的消声量,从而计算出所需消声器的尺寸,对空调机房的设计与净空尺寸提供设计参考。

This paper analyses the attenuation and superposition rule of noise in centralized VRV unit outdoor room according to the principle of noise propagation,studied the noise propagation rule of the air conditioning room under different layers of the air conditioning room and different distance from the residence. Obtained the required noise elimination quantity of the conditioning room with different distance and different layers of air conditioning room under the 'sound environment quality standards'. To calculate the required size of the muffler,and to provide reference for design of the size of air conditioning room.
