There are usually multiple refrigeration facilities and circulating water pumps in the refrigeration room.When the refrigeration room is located directly below the noise sensitive room,the impact of noise and vibration on the upper area cannot be ignored.In this paper,the vibration and noise problems generated by the floor above the refrigerator room in an office building were analyzed.Firstly,the vibration source was diagnosed.Then the pipeline vibration isolation support was designed through modification.Comparing the test data before and after the renovation,the root mean square value of the background noise and vibration acceleration in the office above the refrigeration room after the renovation has reached the national standard,and vibration isolation support has a great vibration isolation efficiency.The original noise and vibration problems have been solved.According to the results,it is suggested that the pipe hanger should not be directly connected to the floor when there is a noise sensitive room above the refrigeration room,and the pipe hanger should be fixed on the beam or column through the vibration isolation system;Or the pipelines vibration isolation support should be installed;All vibration isolation support should be connected one-another to form a system to ensure stability.This paper provides an effective method for vibration isolation and noise reduction of pipelines in the refrigeration rooms.
