Compressor noise reduction device and method

The invention provides a compressor noise reduction device. The compressor noise reduction device is formed by splicing a plurality of sound insulation assemblies, wherein each sound insulation assembly comprises a sealing connecting piece; and the sound insulation assemblies are connected through the sealing connecting pieces, and the connecting positions are sealed to form a sound insulation space. A compressor noise reduction method comprises the steps that the noise reduction device is divided into the multiple sound insulation assemblies, and each sound insulation assembly comprises the corresponding sealing connecting piece; and after the sound insulation assemblies are spliced around a compressor through the sealing connecting pieces and sealed, the compressor is arranged in the sealed sound insulation space formed through splicing. According to the device and method, the complete sound insulation space is formed in a splicing manner, mounting is more flexible, and the splicingmanner and the number of
