空气源热泵机组的噪声源分析热泵机组噪声又称热泵振动噪音、热泵声振动、热泵机组的噪声、热泵机组的结构噪声,它属于物理性质上的噪声。一般根据噪声传播方式的不同,可以采取隔振、消声器、隔声等方式处理热泵机组的噪声。空气源热泵属于低频噪声这块,低频噪声的主要特点就是衰减缓慢、声波较长、穿透能力强,所以低频的噪声一般不易处理。

The noise source analysis of air source heat pump unit is called noise of heat pump unit, noise of heat pump, noise of heat pump, noise of heat pump unit and structural noise of heat pump unit. It belongs to the noise of physical property. Generally, the noise of heat pump units can be treated by vibration isolation, muffler and sound insulation according to the different modes of noise transmission. Air source heat pump belongs to low frequency noise. The main characteristics of low frequency noise are slow attenuation, long sound wave and strong penetrating ability, so low frequency noise is not easy to handle.

1、大型热泵的实测噪声级与销售商提供的噪声指标或样本上标明的噪声级有一定的差别,实测的噪声都要超出3~10dB。一般的热泵A声级噪声为79~82dB,有的热泵超过90dB。如果在居民楼附近或办公楼顶上安装数台热泵,热泵的噪声必然要对周围环境造成较大的影响。


1. The measured noise level of large heat pump is different from the noise index provided by the seller or the noise level indicated on the sample, and the measured noise should exceed 3~10dB. The general heat pump A sound level noise is 79~82dB, and some heat pumps are more than 90dB. If a number of heat pumps are installed near the residential building or on the office roof, the noise of the heat pump must have a greater impact on the surrounding environment.

2、大型热泵的噪声是开放性的,噪声主要从热泵的两侧和顶部向外辐射,辐射噪声的面积较大。如顶部的排风扇台数较多,多的有近百台,总面积可达12m2以上,两侧的面积也有十几平方米,噪声从如此大的面积传播出去,影响范围大,衰减慢,在热泵两侧3m范围内噪声基本上无衰减,在热泵长度以内距离衰减率为3dB。

2. The noise of large-scale heat pump is open, the noise mainly radiates from both sides and top of the heat pump, and the area of radiation noise is larger. The number of rows as the top of the fan, there are more than hundred units, a total area of more than 12m2, on both sides of the area also has a dozen square meters, the noise from the spread in such a large area, a large area of effect, slow attenuation, in the range of 3M on both sides of pump noise basically no attenuation within the heat pump length distance the decay rate of 3dB.

3、热泵的噪声频率特性一般呈中性低频特性,其中主要的噪声频率是63~500Hz,低频噪声的距离衰减慢,影响范围广,不容易消除。

3, the noise frequency characteristics of the heat pump are generally neutral low frequency, the main noise frequency is 63~500Hz, the low-frequency noise attenuation is slow, the influence scope is wide, and it is not easy to eliminate.

4、由于一般热泵的底部往往没有全封闭底盘,只有钢结构框架,压缩机都支撑在框架上,因此噪声也从底部向下传播。如果热泵是安装在屋顶上,向下传播的噪声被楼板挡住形成反射,若是安装在有缝隙或孔洞的结构平面上,噪声将从缝隙或孔洞传播出去。

4, because the bottom of the general heat pump is often not fully closed chassis, only the steel frame, compressors are supported on the framework, so the noise also spread down from the bottom. If the heat pump is mounted on the roof, the downward noise is reflected by the floor, and if it is installed on a flat surface with gaps or holes, the noise will spread through the gap or hole.
