如何降低保鲜柜的噪音干扰？
保鲜柜的噪音一般会让人觉得非常头疼，尤其是用于超市里的这种商用大型设备，发生噪音事故不但会造成自己的困扰，还会影响周边逛超市的购物人群，后果非常严重。所以超市在规划之前就应该确定好压缩机的放置位置，尽量避免压缩机噪音打扰逛超市的购物人群。
常见的保鲜柜噪音是压缩机工作时候发出来的噪音，正常范围应该是30-50分贝之间，噪音超过50分贝一般是压缩机机组故障造成的，主要原因有：毛细管长度不正确是最常见的噪音发生原因，毛细管的长度过短会造成压缩机冷柜不能顺利的到达蒸发器，堵塞造成噪音;保鲜柜的噪声主要来源于压缩机的工作声音，蒸发器或冷凝器的热胀冷缩声音;制冷剂在管路中的声音;产品放置不平产生的声音以及管道之间产生共振碰撞都会发出噪音。
1.根据产品的实际要求来适配毛细管的长度，不懂的情况下应该由专业人士指导并且完成保鲜柜毛细管适配的工作;
2.压缩机底座要上牢固，如果用手紧按压缩机后，噪声明显减低，将手抬起噪声又增大，一般是压缩机底座固定减振胶垫受力不均或螺栓松动、压缩机底板不牢固造成，应调整、拧紧连接部分螺栓和更换失去弹力的垫圈;
3.管路与箱体加固牢靠，要检查调整外管路与箱体之间连接加固部分是否松动，从而避免压缩机工作时产生共振。所以，外管路一定要固定好，螺栓要加弹簧垫圈，以防松动;
4.良好的保鲜柜机组散热环境能够帮助保鲜柜更好工作，保证稳定性的前提下经常保养还能极大降低保鲜柜发出噪音的几率。
The noise of fresh-keeping cabinet will be very troublesome. Especially when used in supermarket, the noise accident will not only cause itself trouble, but also affect the shopping crowd around the supermarket. The consequences will be very serious. So the supermarket should determine the position of the compressor before it is planned, and try to avoid the noise of the compressor to disturb the shopping crowd in the supermarket.
Fresh cabinet is common when the compressor noise from noise, the normal range should be 30-50 decibels, noise exceeding 50 dB is generally caused by compressor failure, the main reasons are: capillary incorrect length is one of the most common causes of noise, the capillary length is too short will cause the compressor refrigerator failto reach the evaporator blockage caused by noise; noise fresh-keeping cabinet mainly comes from the work of the compressor evaporator or condenser sound, thermal expansion and contraction of the sound; sound refrigerant in the pipeline; the product is placed between uneven sound generated and pipeline resonance collision will emit noise.
1., according to the actual requirements of the product, we can match the length of the capillary. If we don't understand it, we should be guided by professionals and finish the work of capillary fit for the fresh-keeping cabinet.
2. compressor to be on a solid base, if the compressor by hand tight, the noise significantly reduced, will be hand to lift the noise increases, the compressor is generally base fixed damping rubber pad force or bolts are loose, the compressor base unstable caused, should adjust and tighten the connection bolt and replace the loss of elastic gasket;
3. pipe and box reinforcement solid, to check the adjustment of the external pipeline and the box connection between the reinforcement part is loose, so that the compressor work to avoid resonance. Therefore, the external pipeline must be fixed, bolt should add spring washer, in order to prevent loose;
4., good heat preservation environment of fresh cabinet can help the cabinet work better, maintain regular maintenance under the premise of stability, and greatly reduce the probability of noise from fresh cabinet.
