Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a central air conditioning soundproof ventilation duct. Background Technology

[0002] Soundproof air conditioning ducts are special ducts used in air conditioning systems to reduce noise generated during operation. They typically employ special materials and structural designs, such as using sound-absorbing materials like glass wool and rock wool on the inner walls of the duct. These materials effectively absorb sound waves and reduce noise propagation. Simultaneously, the duct structure may incorporate sound-absorbing designs, such as silencer elbows and plenum chambers, to further reduce noise by altering the propagation path and manner of sound waves.

[0003] Air conditioning ducts are typically constructed by splicing together multiple square tubes. In actual use, there is a risk of air leakage at the joints. Once air leaks, the negative impacts are significant. On the one hand, it generates considerable noise, disturbing the tranquility of the indoor environment, which is extremely annoying in places such as offices and bedrooms; on the other hand, key functions such as heating and cooling will be greatly reduced, making it difficult to maintain the indoor temperature within the set range, affecting comfort. Moreover, with prolonged and continuous use, dust will continuously accumulate inside the ducts, and this dust will continuously enter the room through the ducts, polluting the indoor air.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Combined with appendix Figure 2 Appendix Figure 4 Appendix Figure 5 A central air conditioning soundproof ventilation duct includes: a frame comprising an upper frame 1 and a lower frame 2, wherein the lower frame 2 is tightly joined below the upper frame 1 to form a square frame shape, and the lower frame 2 and the upper frame 1 are detachable. An extension edge 7 is integrally formed on the upper end of the side wall of the lower frame 2, and the extension edge 7 is connected and fixed to the lower wall of the upper frame 1 by several screws, making the connection between the upper frame 1 and the lower frame 2 more stable and facilitating disassembly for easy maintenance and repair of the duct. A sealing gasket is provided at the joint between the upper frame 1 and the lower frame 2 to enhance the sealing of the frame connection, prevent air leakage in the duct, improve the overall performance of the ventilation duct, and reduce energy loss.

[0025] Combined with appendix Figure 1 Appendix Figure 5 The upper frame 1 and the lower frame 2 are provided with connected air duct grooves 3 on the front and rear sides. The side wall of the air duct groove 3 is provided with a sealing strip 8, which can improve the sealing of the connection between the air duct and the air duct, prevent the air in the air duct from escaping from the connection gap, and thus enhance the sound insulation and ventilation effect.

[0026] Combined with appendix Figure 1 Appendix Figure 2 The honeycomb sound-absorbing panel 4 is symmetrically bonded to the inner wall of the frame. The honeycomb sound-absorbing panel 4 is also connected to the inner wall of the upper frame 1 and the lower frame 2 on the same side, which ensures the integrity and stability of the sound-absorbing panel installation, and can better absorb the noise in the air duct and improve the sound insulation effect.

[0027] Combined with appendix Figure 1 Appendix Figure 3 The filter assembly, detachably mounted inside the upper frame 1, includes a support frame 5 and a filter screen 6, with the filter screen 6 fixedly mounted inside the support frame 5. The upper wall of the upper frame 1 has a mounting groove for the support frame 5 to slide through. The upper wall of the support frame 5 extends to both ends, and both ends are connected and fixed to the upper frame 1 with screws. This facilitates the installation, disassembly, and cleaning of the filter assembly while ensuring its stability. A handle groove 9 is located in the middle of the upper wall of the support frame 5, allowing for easy hand gripping and making installation and disassembly of the filter assembly more convenient and efficient.

[0028] The specific implementation of this utility model is as follows: First, installation preparation is carried out by connecting the upper frame 1 and the lower frame 2.
