Problems solved by technology

Due to the small specific gravity of the EPDM foam sound insulation cover, although it can play a certain role in sound insulation, it is difficult to effectively block the noise generated by the high-frequency operation of the compressor; moreover, the aging resistance of the EPDM foam material is poor. Difficult to disassemble after forming, inconvenient for later use and maintenance

Abstract

The invention provides a sound-insulation shield of a compressor. The sound-insulation shield comprises a galvanized sheet casing, wherein a felt sound-insulation liner is arranged on the inner layer of the galvanized sheet casing. The sound-insulation shield adopts a double-layer structure, greatly increases the specific gravity of sound-insulation materials by matching the galvanized sheet casing with the felt liner, effectively enhances the sound-insulation effect, and insulates sharp noises of the compressor in high frequency. Products are integrally convenient to process and easy to mount and demount, and can be directly assembled and installed on the existing air conditioner outdoor units, and the integral stability and reliability in installation can be ensured. Simultaneously, production cost is saved.

Description

technical field [0001] The invention relates to a soundproof cover, in particular to a soundproof cover for an air conditioner compressor. Background technique [0002] In recent years, the air conditioning industry has developed rapidly, and the frequency conversion multi-connected air conditioners have been more and more applied to villa projects. The multi-connected air-conditioning outdoor units used in the villa group are generally installed in the villa yard or on both sides of the villa, close to the villa. The noise generated by the compressor at high frequency makes the human body living in the villa feel uncomfortable and unacceptable. [0003] At present, the sound insulation of compressors mainly adopts EPDM foam sound insulation cover technology. The most commonly used EPDM foam is 7mm, and the foaming ratio is 10~11 times. Due to the small specific gravity of the EPDM foam sound insulation cover, although it can play a certain role in sound insulation, it is d...
