Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning installation, and particularly relates to a noise reduction structure of an outdoor unit of a central air-conditioning. Background Art

[0002] Air conditioning or air conditioner refers to equipment that uses artificial means to adjust and control parameters such as temperature, humidity, flow rate, etc. of the ambient air in a building or structure. It generally includes several major parts such as cold source or heat source equipment, cold and hot medium distribution system, terminal device and other auxiliary equipment, mainly including outdoor unit structure, water pump, fan and piping system.

[0003] However, in actual use, most of the central air-conditioning outdoor unit structures are directly suspended on the support. In addition, since most installation methods are mainly installed through support frames, the vibration of the slot when the air-conditioning is running will cause the installation point to loosen, and aging will occur with long-term use, causing the noise to expand, thus forming noise. Therefore, we proposed a central air-conditioning noise reduction structure. Utility Model Content

[0004] The purpose of the utility model is to provide a noise reduction structure for an outdoor unit of a central air conditioner. When the vibration reduction component is in use, the cross plate is fixed to the vibration reduction component through the cooperation of screw four and the nut. When the air conditioner is started, the vibration generated will squeeze the shock-absorbing spring downward due to the cooperation of the limit block and the limit ring. The shock-absorbing spring fixes the support plate and the bottom plate respectively to achieve a shock-absorbing effect. The vibration generates noise, thereby reducing noise. This solves the problem that most of the existing central air-conditioning outdoor unit structures are directly suspended on the support and most of the installation methods are mainly installed through the support frame. When the air conditioner is running, the vibration generated in the slot will cause the installation point to loosen, and aging will occur with long-term use, thereby causing the noise to expand, thereby forming noise.
