Abstract
Claims
1. A noise reduction system for an air conditioning unit, comprising a housing (1), a base (2) provided at the bottom of the housing (1), an air conditioning unit body (3) installed inside the housing (1), and an air inlet (4) provided at the front side of the housing (1). characterized in that The housing (1) is provided with a sound-absorbing sleeve (5) inside. The sound-absorbing sleeve (5) surrounds the outside of the air conditioning unit body (3). Foam metal (7) is installed between the middle of the outer side of the sound-absorbing sleeve (5) and the middle of the inner wall of the housing (1). Buffer seats (8) are symmetrically arranged on both sides of the foam metal (7). The top of the buffer seat (8) is fixedly connected to the housing (1), and the bottom of the buffer seat (8) is fixedly connected to the sound-absorbing sleeve (5). The base (2) is symmetrically equipped with a sleeve (10) on the top. A sliding plate (11) is slidably connected through the top of the sleeve (10). A magnetic sheet (12) is installed on the bottom of the sliding plate (11) and the bottom of the sleeve (10) on opposite surfaces. A second buffer damping spring (13) is provided on both sides inside the sleeve (10).
2. The noise reduction system for an air handling unit of claim 1, wherein: The sound-absorbing sleeve (5) is configured as a rectangular structure, and the sound-absorbing sleeve (5) has equally spaced sound-absorbing holes (6) on its exterior. The sound-absorbing sleeve (5) and the sound-absorbing holes (6) constitute an internal noise reduction structure, and the foam metal (7) constitutes a buffer and shock absorption structure.
3. The noise reduction system for an air handling unit of claim 2, wherein: The buffer seat (8) is configured as a triangular structure. The buffer seat (8) is composed of two rotating and interlocking buffer plates, and a first buffer damping spring (9) is installed between the outer side of the buffer plate and the inner wall of the shell (1).
4. The noise reduction system for an air handling unit of claim 3, wherein: The buffer seat (8) rotates under force and the mechanical vibration is buffered by stretching the first buffer damping spring (9). The foam metal (7) and the buffer seat (8) together form an internal shock absorption and noise reduction structure.
5. The noise reduction system for an air handling unit of claim 4, wherein: The bottom of the sleeve (10) and the bottom of the magnetic plate (12) of the slide plate (11) have the same magnetic poles. The sleeve (10), slide plate (11), magnetic plate (12) and the second buffer damping spring (13) constitute an external shock absorption and noise reduction structure.
6. The noise reduction system for an air handling unit of claim 5, wherein: The slide plate (11) and the sleeve (10) are connected by a sealed sliding connection. The bottom of the sleeve (10) is connected to the front and rear fixed cylinders (14) through a connecting pipe. The fixed cylinders (14) are symmetrically installed on the front and rear sides of the top of the base (2).
7. The noise reduction system for an air handling unit of claim 6, wherein: The top of the fixed cylinder (14) is sealed and slidably connected to a piston plate (15). The top of the piston plate (15) abuts against the bottom of the housing (1). Sound insulation pads are provided at the contact points between the top of the sliding plate (11) and the piston plate (15) and the housing (1).
