空氣源熱泵機組的噪聲源分析熱泵機組噪聲又稱熱泵振動噪音、熱泵聲振動、熱泵機組的噪聲、熱泵機組的結構噪聲，它屬于物理性質上的噪聲。一般根據噪聲傳播方式的不同，可以采取隔振、消聲器、隔聲等方式處理熱泵機組的噪聲?？諝庠礋岜脤儆诘皖l噪聲這塊，低頻噪聲的主要特點就是衰減緩慢、聲波較長、穿透能力強，所以低頻的噪聲一般不易處理。

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、大型熱泵的實測噪聲級與銷售商提供的噪聲指標或樣本上標明的噪聲級有一定的差別，實測的噪聲都要超出3~10dB。一般的熱泵A聲級噪聲為79~82dB，有的熱泵超過90dB。如果在居民樓附近或辦公樓頂上安裝數臺熱泵，熱泵的噪聲必然要對周圍環境造成較大的影響。

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、大型熱泵的噪聲是開放性的，噪聲主要從熱泵的兩側和頂部向外輻射，輻射噪聲的面積較大。如頂部的排風扇臺數較多，多的有近百臺，總面積可達12m2以上，兩側的面積也有十幾平方米，噪聲從如此大的面積傳播出去，影響范圍大，衰減慢，在熱泵兩側3m范圍內噪聲基本上無衰減，在熱泵長度以內距離衰減率為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、熱泵的噪聲頻率特性一般呈中性低頻特性，其中主要的噪聲頻率是63~500Hz，低頻噪聲的距離衰減慢，影響范圍廣，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、由于一般熱泵的底部往往沒有全封閉底盤，只有鋼結構框架，壓縮機都支撐在框架上，因此噪聲也從底部向下傳播。如果熱泵是安裝在屋頂上，向下傳播的噪聲被樓板擋住形成反射，若是安裝在有縫隙或孔洞的結構平面上，噪聲將從縫隙或孔洞傳播出去。

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.
