Description

Technical Field

[0001] This application relates to the field of fresh air system technology, specifically to a central fresh air integrated unit with disinfection and purification functions. Background Technology

[0002] Fresh air systems are typically designed and function to address indoor air quality issues by introducing fresh outdoor air to improve ventilation, reduce carbon dioxide concentration, and enhance the comfort of living or working environments. However, existing technologies have significant limitations. Many fresh air systems lack efficient filtration and disinfection mechanisms in the air exchange process, due to factors such as design complexity, cost considerations, or technological constraints.

[0003] Traditional fresh air systems often only have basic filtration functions, potentially removing only larger dust particles. Their effectiveness is often insufficient for filtering tiny pollutants such as pollen, bacteria, and viruses. These tiny particles can penetrate ordinary filters, enter the room, and remain suspended in the air, posing a risk to allergy sufferers and those with weakened immune systems. Furthermore, fresh air systems may not be designed with dynamic, real-time disinfection capabilities in mind. Therefore, even if some air is filtered before entering the room, without effective disinfection, viruses and bacteria may still survive, a problem particularly acute during periods of high infectious disease activity.

[0004] Due to the aforementioned issues, users of fresh air systems may face the risk of insignificant improvement in air quality, or even a decline in indoor air quality due to the introduction of outdoor pollutants. Utility Model Content

[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0028] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0029] A central fresh air unit with disinfection and purification functions, referring to Figure 1 and Figure 2It includes an outer shell 1. Inside the outer shell 1, in the middle position, there is a filter device, an air disinfection module 2, a heat exchange core 3, and several partition plates 4. The partition plates 4 divide the interior of the outer shell 1 into four cavities. The air disinfection module 2 and the filter device are both installed on the heat exchange core 3.

[0030] The outer shell 1 corresponding to the four cavities is respectively provided with a fresh air inlet 5, a fresh air outlet 6, an exhaust air inlet 7, and an exhaust air outlet 8. The fresh air inlet 5 and the exhaust air outlet 8 are located on one side of the outer shell 1, and the fresh air outlet 6 and the exhaust air outlet 8 are located on the other side of the outer shell 1. Among them, the fresh air inlet 5 and the exhaust air inlet 7 are opposite each other, and the fresh air outlet 6 and the exhaust air outlet 8 are opposite each other, so that the line connecting the fresh air inlet 5 and the fresh air outlet 6 and the line connecting the exhaust air inlet 7 and the exhaust air outlet 8 intersect.

[0031] The heat exchange core 3 has a rectangular parallelepiped structure and is inclinedly installed inside the outer shell 1. Its four sides correspond to and are connected to four cavities. The fresh air inlet 5 is positioned opposite the filter device and the air disinfection module 2, so that the air at the fresh air inlet 5 passes through the filter device and the air disinfection module 2 before entering the heat exchange core 3.

[0032] Fresh air introduced through the fresh air inlet 5 is first filtered and disinfected by the filter and air disinfection module 2 before entering the heat exchange core 3. Indoor air enters directly into the heat exchange core 3 through the exhaust inlet 7. Heat exchange occurs between the fresh air and indoor air within the heat exchange core 3, making the fresh air more adaptable to the indoor temperature and ensuring comfort for the occupants. After heat exchange, the fresh air is exhausted into the room through the fresh air outlet 6, bringing clean, fresh air into the room.

[0033] The filtration device includes a primary filter 9, a medium-efficiency filter 10, and a high-efficiency filter 11. The primary filter 9 and the medium-efficiency filter 10 are installed on one side of the heat exchange core 3, and the high-efficiency filter 11 is installed on the opposite side of the heat exchange core 3. This ensures that the primary filter 9 and the medium-efficiency filter 10 are located within the cavity corresponding to the fresh air inlet 5, and the high-efficiency filter 11 is located within the cavity corresponding to the fresh air outlet 6. During installation, the medium-efficiency filter 10 is installed on the heat exchange core 3, and the primary filter 9 is installed on the side of the medium-efficiency filter 10 facing away from the heat exchange core 3. This allows air at the fresh air inlet 5 to pass sequentially through the primary filter 9, the medium-efficiency filter 10, and the heat exchange core 3. Air exiting the heat exchange core 3 passes through the high-efficiency filter 11 before reaching the fresh air outlet 6.

[0034] In this embodiment, the primary filter 9 uses a washable metal wire mesh, which can effectively intercept large particles of dust, hair, and other pollutants in the air. The medium-efficiency filter 10 uses glass fiber or synthetic fiber material to further filter fine dust and pollen in the air. The high-efficiency filter 11 uses a HEPA (High-Efficiency Particulate Air) filter, which can achieve a filtration efficiency of over 99.97% for particles with a diameter of 0.3 micrometers or larger, effectively removing tiny particles and bacteria from the air.

[0035] Air disinfection module 2 employs a combination of disinfection technologies, including ultraviolet lamps and hydroxyl catalyst plates. The ultraviolet light emitted by the lamps can destroy the DNA and RNA structures of bacteria and viruses, thereby achieving sterilization and disinfection. The wavelength of the ultraviolet lamps can be set to 253.7nm, which provides the optimal sterilization effect.

[0036] A fresh air fan 12 and an exhaust fan 13 are installed inside the outer casing 1. The fresh air fan 12 is located between the heat exchange core 3 and the fresh air outlet 6, and the exhaust fan 13 is located between the heat exchange core 3 and the exhaust outlet 8, providing power for airflow. In some embodiments, both the exhaust fan 13 and the fresh air fan 12 can be high-efficiency and energy-saving centrifugal fans, capable of automatically adjusting the air volume according to indoor and outdoor air quality and ventilation requirements.

[0037] The outer casing 1 also houses a control system. This control system includes a control box 14 and several sensors. The control box 14 uses a microprocessor (MCU) as its control core. The sensors monitor indoor and outdoor air quality parameters such as PM2.5 concentration, temperature, humidity, CO2 concentration, and TVOC. The sensors, air disinfection module 2, fresh air fan 12, and exhaust fan 13 are all electrically connected to the control box 14. The control box 14 receives data from the sensors and adjusts the operating status of the air disinfection module 2, fresh air fan 12, and exhaust fan 13 based on the monitoring results, achieving intelligent operation.

[0038] In addition, the control system is also equipped with a fault alarm module and a remote control module to facilitate user operation and maintenance.

[0039] The outer shell 1 is made of high-strength, corrosion-resistant materials, and the internal modules are compact and rationally designed, ensuring the reliability and stability of the equipment.

[0040] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
