Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning noise reduction, in particular to a noise reduction device for an air-conditioning compressor. Background Art

[0002] Air conditioning consists of four parts: refrigeration (heat) circulation system, air circulation and ventilation system, electrical control system and air conditioning box, mainly including refrigeration host, water pump, fan and piping system.

[0003] A Chinese patent discloses a noise reduction structure for refrigeration equipment, with publication number CN221897886U, which includes an air-conditioning outdoor unit, a mounting foot, a mounting support, and a vibration reduction and reinforcement device. The utility model sets a vibration reduction and reinforcement device on the inner side of the mounting support. After the air-conditioning outdoor unit is installed, the pull rod is rotated in the opposite direction to unscrew the threaded section from the threaded sleeve to release the lock on the bracket. At this time, the support spring pushes the bracket upward into the inner chamber, so that the bracket is tightly supported on the bottom of the air-conditioning outdoor unit. Even if the bolts on the mounting foot become loose, the air-conditioning outdoor unit will be supported and tightened from below by the bracket, reducing the mobility of the air-conditioning outdoor unit and making it less likely to make collision noises, thereby achieving a noise reduction effect. By setting a sound-reflecting plate at the rear of the mounting support, the sound-reflecting plate plays the role of reflecting sound waves, so that the noise generated by the air-conditioning outdoor unit is not easily transmitted through the sound-reflecting plate into the room, thereby achieving a noise reduction effect.

[0004] However, there are still some disadvantages: the device uses a rubber layer for shock absorption and a sound-reflecting plate for sound wave reflection, which cannot reduce the noise emitted by the air conditioner outdoor unit and still causes noise pollution. Therefore, we propose a noise reduction device for air conditioner compressor to solve this problem. Utility Model Content
