Design and practice of vibration isolation and noise reduction of heat exchanger room in super high-rise residential buildings

In this paper, the vibration and noise problems caused by the heat exchanger room of the equipment conversion layer of a super high-rise residential building are analysed, the noise source is diagnosed, the vibration isolation design and transformation are carried out, and the test data and subjective evaluation before and after the transformation are compared. The results show that after the transformation, the background noise in the upper and lower residences adjacent to the heat exchanger room meets the requirements of the national standards and specifications, and the vibration isolation and noise reduction effect is excellent, which solves the original structural noise problem. It provides an effective and reliable control method for vibration isolation and noise reduction of equipment in the conversion layer of super high-rise residential buildings.
