热泵降噪措施研究与实践

Research and Practice on Noise Control of Heat Pump

热泵机组由于具有节能环保及冷暖联供等特点,目前在国内应用广泛。但单台或多台热泵机组的工作噪声易对周围环境产生一定影响,已成为近期城市中一类带有普遍性的固定源噪声污染问题。通过分析风冷式热泵机组的噪声源特性,在满足热泵正常运行所需要的通风散热等条件下,总结出多种应用于不同情况下的噪声治理措施,并经实践检验,降噪效果显著。

Heat pump units have been widely used in domestic because of their characteristics of energy saving and protecting environment. However, their noises have some bad impacts on the environment around,which has become a serious problem of noise pollution. This paper try to obtain various noise-control measures applied to different situations through analyzing noise transmission characteristics of heat pump units under natural conditions of ventilation and cooling. In practice, The noise pollution of the hot pump units has been reduced obviously by effective measures。
