| 摘 要： | 风冷式热泵噪声对周围环境产生一定的影响，已成为城市中带普遍性的固定噪声源，在调查分析热泵噪声及其传播特性的基础上，以两个实例剖析了热泵机组噪声治理中，距离衰减低，排风余压小（50Pa)，安装条件限制等技术措施，结果表明，采用全封闭的隔声消声装置，能把热泵的噪声传播影响降低20dB（A）左右。

| Abstract: | Noise from air cooling heat pump has become a noise pollution source in the city and caused certain effects on the environment. Based on investigating analysis on heat pump noise characteristics and its spreading character, taking two actual cases to analyze in heat pump set noise treatment, under low distance attenuation, low exhaust air remain pressure (50Pa), and limitation of assembling conditions technical measures, the result showed that using enclosed device of sound insulation, the noise could eliminate about 20dB(A). |
