【摘要】 随着现代科学技术的发展和人们生活水平的提高,空调系统在我国民用建筑中的使用越来越广泛。空调系统的应用,改善了空调房间内的小气候,给人们带来了比较舒适的温度、湿度环境。民用建筑中的空调系统给人们的生活、工作、休闲等活动带来舒适的同时,也带来了不容忽视的声环境污染问题。并且,随着人们对健康、环境等问题的意识不断提高,空调系统产生的噪声问题将会越来越受到人们的重视。本文针对民用建筑的空调系统,比较系统、全面地分析了空调系统存在的噪声源,并对部分空调设备的发声机理进行了分析。民用建筑空调系统常采用的噪声控制措施有:消声、吸声、隔声和隔振。针对不同的设备,应该采取不同的噪声控制措施,通常是几种噪声控制措施综合运用才能达到较好的噪声控制目的。另外,利用声场模拟软件Raynoise,对一水泵机房进行了声场的模拟,用以分析经过隔声降噪处理后,可以达到的降噪效果。民用建筑空调系统的噪声控制比较复杂,而从事空调专业的设计人员往往缺乏相关的声学知识和技能,所以本文希望能够为空调设计人员提供一些必要的关于空调系统噪声控制的理论基础,设计方法以及控制措施。更多还原

【Abstract】 With the development of modern science & technology and people’s standard of living,air-condition systems have been being applied to the civil architecture in our country more and more broadly. With the application of air-condition systems,it improves the microclimate in the conditioned rooms. It brings people comfortable environment with fitting temperature and humidity. Although air-condition systems in civil architecture bring people comfort in their life,work,recreation and some other activities,it also cause acoustics environment problems that can not be ignored. Besides,along with people’s consciousness on health,environment etc,noise problems caused by air-condition systems will be more and more valued by people.This paper focus on air-condition systems in the civil architecture,analyze the noise source that exist in the air-condition systems roundly,and also make a simple explanation of the reason how some of the equipment produce noise. The method that are usually used to control noises in the air-condition systems of civil architecture are : noise elimination,sound absorption,sound insulation and vibration insulation. To different equipment,we should use different control methods. Usually, the combination of these noise control methods could reach a good effect. The noise control of air-condition systems in civil architectures is complicated. Meanwhile,the people engaged in the air-condition design don not know much about correlative acoustics knowledge and skills. So this paper expects to provide some necessary basic principles,design and control methods about air-condition system noise control for air-condition system designer.Besides,using the software Raynoise for sound field simulation to simulate the sound field of a pump room and check out the noise control effect.更多还原
