摘要
目的:降低医院制冷机房内制冷机组和冷却塔的噪声,改善噪声污染。方法:分析噪声来源,根据不同的噪声源采取不同的措施,确保机组的正常运行,减少噪声对周围居民的影响。结果:经过一系列的改造,使厂界外的居民楼噪声达到了标准要求。结论:对于机房和冷却塔噪声的治理,要综合运用吸声、隔声和减振等多种方法,各种材料的选取要力求控制低频区的噪声。
Objective To decrease the noise from the air-conditioning plant and cooling tower in the hospital. Methods The measures were determined according to the noise sources to ensure the normal operation of the air conditioners and to eliminate the influence of noise on the adjacent residents. Results The noise around the oozing was decreased to meet the requirements. Conclusion The methods, such as sound absorption, isolation and vibration reduction, along with multiple materials have to be mobilized to eliminate the noise.
