Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, specifically to a low-noise integrated air conditioning unit's air inlet and outlet duct. Background Technology

[0002] As people's living standards continue to improve, their demands for comfort during air conditioning use are also increasing. Operating noise and energy efficiency are important indicators for evaluating air conditioning performance. In existing integrated air conditioning units, the design of the air inlet and outlet ducts often has certain flaws. Traditional integrated air conditioning units suffer from poor heat transfer efficiency due to their inlet and outlet ducts. Their poorly designed ducts result in a small contact area between the airflow and the condenser, leading to insufficient heat transfer. This causes the air conditioner to consume more energy to achieve cooling or heating, thus reducing its energy efficiency. Furthermore, the noise generated by the fan and the airflow within the ducts cannot be effectively controlled, resulting in significant noise levels during operation and severely impacting the user experience. To address these issues, some technologies attempt to reduce noise by optimizing the fan structure or adding sound insulation materials. However, these methods often only solve a single problem and cannot simultaneously achieve the dual goals of noise control and energy efficiency improvement. Therefore, it is necessary to design a low-noise integrated air conditioning unit's inlet and outlet air duct. Utility Model Content

[0021] Please see Figures 1-4 This utility model discloses a low-noise air conditioner integrated unit air inlet and outlet duct, including an external fan motor mechanism 1, a sound-absorbing and sound-insulating air duct 2 and a condenser 3; The external fan motor mechanism 1 is located at the air inlet end of the air inlet and outlet duct, and is used to draw in air and blow the airflow into the sound-absorbing and sound-insulating duct. The air inlet of the sound-absorbing and sound-insulating air duct 2 is connected to the air outlet of the external fan motor mechanism 1, and the air outlet of the sound-absorbing and sound-insulating air duct 2 is connected to the condenser 3, which is used to guide the airflow to the condenser to achieve heat transfer. The sound-absorbing and sound-insulating air duct 2 is equipped with a flow guiding structure 4 inside.

[0022] In this utility model, the external fan motor mechanism 1 includes a left sealing plate 12, a right sealing plate 13, a front sealing plate 14, a rear sealing plate 15, a chassis 16, a motor 17, and a compressor 18. The left sealing plate 12, right sealing plate 13, front sealing plate 14, rear sealing plate 15, and chassis 16 are spliced ​​to form a receiving cavity. The motor 17 and compressor 18 are both installed in the receiving cavity. The compressor 18 is connected to the motor 17. An electrical control mounting plate 19 is installed on the inner side of the left sealing plate 12. An air outlet is opened on the rear sealing plate 15, and the air outlet is connected to the sound-absorbing and sound-insulating air duct 2.

[0023] In this invention, the airflow guiding structure 4 includes multiple staggered airflow guiding plates 5. The surface of the airflow guiding plate 5 is provided with sound-absorbing material, which can guide the airflow to flow evenly and absorb the noise generated by the airflow.

[0024] In this invention, the inner wall of the sound-absorbing and sound-insulating air duct 2 has a wave-shaped structure 6. This structural design increases the contact area between the air duct and the airflow, allowing for more thorough heat exchange between the airflow and the inner wall of the duct, thereby greatly improving heat removal efficiency. The sound-absorbing and sound-insulating air duct 2 is made of a multi-layer composite structure, comprising, from the inside out, a sound-absorbing layer 7, a sound-insulating layer 8, and a heat-insulating layer 9. The sound-absorbing layer 7 is made of glass wool, the sound-insulating layer 8 is made of damping sound insulation board, and the heat-insulating layer 9 is made of polyurethane foam. The sound-absorbing layer effectively absorbs noise generated by the airflow; the sound-insulating layer further blocks the transmission of noise; and the heat-insulating layer prevents heat loss within the air duct, improving heat transfer efficiency.

[0025] In this invention, a transition structure is provided at the connection between the sound-absorbing and sound-insulating air duct 2 and the condenser 3. The transition structure includes a gradually changing guide surface 10, which enables the airflow to smoothly transition from the air duct to the condenser, reducing airflow resistance and turbulence, further reducing noise and improving heat transfer efficiency.

[0026] In addition, this utility model also includes a wind speed adjustment component, which includes an adjustable wind deflector 11 installed at the air outlet of the external fan motor 1. The airflow speed is controlled by adjusting the angle of the adjustable wind deflector, thereby adjusting the exhaust wind speed and increasing the exhaust wind speed by 3% - 5% compared with the original technology, effectively enhancing the air conditioning energy efficiency.

[0027] Working Principle: When the integrated air conditioner is running, the outdoor fan motor starts working, drawing in air and blowing it into the sound-absorbing duct. As the airflow moves within the duct, the guide structure directs the airflow evenly, and the sound-absorbing material on the guide plate absorbs noise generated by the airflow. Simultaneously, the multi-layered composite structure of the duct further blocks noise. The wavy structure of the duct's inner wall increases the contact area with the airflow, allowing heat to be carried away more effectively. During the airflow from the sound-absorbing duct to the condenser, the gradually changing guide surface of the transition structure ensures a smooth transition, reducing resistance and turbulence. By adjusting the angle of the adjustable baffle plate in the fan speed control device, the airflow speed can be controlled to achieve a suitable range, improving efficiency by 3%-5% compared to previous technologies, effectively enhancing the air conditioner's energy efficiency.

[0028] In summary, this utility model features a novel structural design that solves the problems of high noise and low energy efficiency in the air inlet and outlet ducts of existing integrated air conditioning units, achieving a dual breakthrough in noise control and energy efficiency improvement, and providing users with a quieter and more efficient user experience.
