【摘要】 热泵机组噪声多在80dB(A)以上,必须进行降噪减振设计以控制对环境的噪声污染。本文通过南京电视台演播中心工程三层屋面上热泵机组的噪声振动的控制设计,介绍了暖通设计空调室外机组噪声振动控制的设计方法和要点。在分析和计算了要满足环境允许噪声标准后,给出了一种吸音墙体和隔声挡墙的设计实例,达到了良好的治理效果,对空调系统室外机设计有参考价值。更多还原

【Abstract】 Because the noise value of heat pump almost is above 80 dB(A),noise-reduction and anti-vibration design to control environmental noise pollution must be done.By the example of the noise and vibration control design of three-floor roofing heat pump set in the studio center of Nanjing Television Station,the design methods and design synopsizes of noise and vibration control are presented for outdoor machines of air conditioning units.Through analyzing and computing satisfy environmental noise criteria,a sort of noise absorption wall and sound insulation wall are introduced,which obtained good effect.It has reference value for outdoor machine design in air conditioning system.更多还原
