Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, and in particular to a fresh air oxygenation and purification device with humidity regulation function. Background Technology

[0002] As people's requirements for indoor air quality increase, fresh air systems have become common air handling equipment in modern buildings. Their basic function is to introduce fresh outdoor air into the room after filtration and temperature and humidity regulation, while expelling stale indoor air, thus achieving the exchange of indoor and outdoor air.

[0003] In existing technologies, fresh air systems with humidity control functions typically employ condensation dehumidification or electric heating. These methods suffer from high energy consumption, high noise levels, and inaccurate humidity control. Furthermore, some systems use rotary dehumidifiers, but lack effective strategies for handling low fresh air humidity or situations requiring additional humidification, often necessitating external humidification equipment, leading to system complexity and increased costs. Simultaneously, conventional fresh air systems still require the entire treatment process during transitional seasons or when outdoor air conditions are favorable, resulting in energy waste. Summary of the Invention

[0004] To overcome the technical defects of the existing technology, this utility model provides a fresh air oxygenation and purification device with humidity regulation function.

[0005] The technical solution adopted by this utility model is: a fresh air oxygenation and purification device with humidity regulation function, including a purification shell, a fresh air inlet, a fresh air outlet, an exhaust inlet, and an exhaust outlet disposed on the purification shell. The purification shell is internally provided with a main processing air duct and a bypass dry air duct. A three-way intelligent air valve connected to the fresh air inlet is installed inside the purification shell. The two outlets of the three-way intelligent air valve are respectively connected to the inlets of the main processing air duct and the bypass dry air duct. A filter module, a total heat exchanger, and a rotary humidity regulating component are sequentially arranged along the fresh air flow direction within the main processing air duct. The outlet of the bypass dry air duct bypasses the total heat exchanger and the rotary humidity regulating component and is connected to the main processing air duct after the rotary humidity regulating component. The main processing air duct outlet is connected to the fresh air outlet; the interior of the purification housing is equipped with an exhaust duct connected to the exhaust inlet and exhaust outlet; the rotating humidity control component includes an adsorption wheel located inside the purification housing, with several honeycomb holes on the end face of the adsorption wheel, extending into the main processing air duct and the exhaust duct; a servo motor is installed inside the purification housing to drive the adsorption wheel to rotate; the exhaust side outlet of the total heat exchanger is connected to the exhaust outlet, and the exhaust side inlet of the total heat exchanger is connected to the exhaust duct; humidity sensors are installed in both the main processing air duct and the exhaust duct; a PLC controller is installed on the purification housing, and the humidity sensors and the three-way intelligent air valve are electrically connected to the PLC controller.

[0006] Preferably, the adsorption wheel is made of a solid moisture-absorbing material, and the surface of the honeycomb channels of the adsorption wheel is coated with a nano-scale hydrophilic coating.

[0007] Preferably, a heater is installed inside the exhaust duct. The heater is a PTC ceramic heater and is electrically connected to the PLC controller.

[0008] Preferably, a primary filter is provided in the bypass dry air duct.

[0009] Preferably, the servo motor is electrically connected to the PLC controller.

[0010] The beneficial effects of this utility model are:

[0011] 1. By installing humidity sensors in the main processing air duct and exhaust duct, and combining the linkage control of PLC controller with three-way intelligent air valve and rotary humidity adjustment component, the fresh air oxygenation and purification device can automatically adjust the fresh air humidity according to indoor and outdoor humidity conditions, achieve precise humidification or dehumidification, and adapt to the humidity control needs under different climatic conditions.

[0012] 2. By setting up a bypass dry air duct, when the outdoor air humidity is suitable or dry, some or all of the fresh air can bypass the total heat exchanger and the rotating dehumidification component and be directly sent into the room, reducing processing energy consumption and achieving energy-saving ventilation; at the same time, during the transition season or when the outdoor air quality is good, unnecessary processing is avoided, improving the overall energy efficiency of the system.

[0013] 3. By rotating the humidity control component across the main treatment air duct and the exhaust air duct, the exhaust air is used to regenerate the adsorption wheel, realizing a continuous cycle of moisture absorption and desorption. No additional humidification equipment is required, which simplifies the structure of the fresh air oxygenation and purification device and reduces equipment costs and maintenance difficulty.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0019] like Figure 1 and Figure 2 As shown, this embodiment provides a fresh air oxygenation and purification device with humidity regulation function, including a purification housing 1, a fresh air inlet 2, a fresh air outlet 3, an exhaust inlet 4, and an exhaust outlet 5 disposed on the purification housing 1. The purification housing 1 has a main processing air duct 6 and a bypass dry air duct 7 inside. A three-way intelligent air valve 8 connected to the fresh air inlet 2 is installed inside the purification housing 1. The two outlets of the three-way intelligent air valve 8 are respectively connected to the inlets of the main processing air duct 6 and the bypass dry air duct 7. A filter module 9, a total heat exchanger 10, and a rotary humidity regulating component 11 are sequentially arranged along the fresh air flow direction in the main processing air duct 6. The outlet of the bypass dry air duct 7 bypasses the total heat exchanger 10 and the rotary humidity regulating component 11, and connects to the main processing air duct 6 after the rotary humidity regulating component 11. The outlet of the main processing air duct 6... The purification housing 1 is connected to the fresh air outlet 3; the interior of the purification housing 1 is provided with an exhaust duct 12 connected to the exhaust inlet 4 and the exhaust outlet 5; the rotating humidity control component 11 includes an adsorption wheel 13 located inside the purification housing 1, the end face of the adsorption wheel 13 is provided with several honeycomb holes, the adsorption wheel 13 extends into the main treatment air duct 6 and the exhaust duct 12, a servo motor 18 is installed inside the purification housing 1 to drive the adsorption wheel 13 to rotate, the exhaust side outlet of the total heat exchanger 10 is connected to the exhaust outlet 5, and the exhaust side inlet of the total heat exchanger 10 is connected to the exhaust duct 12; humidity sensors 14 are installed in both the main treatment air duct 6 and the exhaust duct 12, a PLC controller 15 is installed on the purification housing 1, and the humidity sensors 14 and the three-way intelligent air valve 8 are electrically connected to the PLC controller 15.

[0020] The adsorption wheel 13 is made of solid moisture-absorbing material. The honeycomb channel surface of the adsorption wheel 13 is coated with a nano-level hydrophilic coating. The solid moisture-absorbing material has good stability and long life. Combined with the nano-level hydrophilic coating, it increases the contact area and adsorption efficiency between the adsorption wheel 13 and water, making the moisture absorption and desorption process faster and improving the response speed and effect of humidity regulation.

[0021] A heater 16 is installed inside the exhaust duct 12. The heater 16 is a PTC ceramic heater and is electrically connected to the PLC controller 15. The PTC ceramic heater has the characteristics of self-temperature control and high safety. By heating the air flowing through the exhaust duct 12 for the adsorption wheel 13, it can strongly drive the moisture adsorbed in the adsorption wheel 13, so that it can quickly restore its moisture absorption capacity even in low temperature or high humidity environments, ensuring the stable operation of the rotary humidification component under different working conditions.

[0022] The bypass dry air duct 7 is equipped with a primary filter 17, which can ensure that even if the fresh air does not pass through the main treatment air duct 6, it can be preliminarily purified, preventing large outdoor particulate pollutants from directly entering the room and ensuring the basic cleanliness of the supply air in any operating mode.

[0023] The servo motor 18 is electrically connected to the PLC controller 15, enabling precise control of the rotation speed of the adsorption wheel 13. By adjusting the rotation speed of the adsorption wheel 13, the intensity of the moisture absorption and regeneration process can be controlled, thereby achieving the adjustment of the outlet air humidity and meeting different humidity control requirements.

[0024] During operation, when dehumidification is required, most or all of the fresh air passes through the main processing duct 6, driving the adsorption wheel 13 in the rotating humidification component 11 to rotate, thus dehumidifying the air. When humidification is required or the outdoor air is dry, some of the dry fresh air can pass through the bypass dry duct 7, bypassing the moisture-absorbing adsorption wheel 13, and then mix with the air processed by the main processing duct 6. The dry fresh air is used to directly humidify the supply air or reduce the relative humidity. When the outdoor air temperature and humidity are suitable, most of the fresh air can pass through the bypass dry duct 7, reducing the resistance after passing through the total heat exchanger 10 and the rotating humidification component 11, achieving energy-saving ventilation, improving the adaptability of the fresh air oxygenation and purification device to different climatic conditions, and avoiding... This avoids energy waste caused by over-processing; the adsorption wheel 13 of the rotating humidification component 11 spans the main processing air duct 6 and the exhaust duct 12. On the fresh air side, the adsorption wheel 13 absorbs moisture from the fresh air or releases moisture into the dry fresh air. On the exhaust air side, the exhaust air from the exhaust duct 12 regenerates the adsorption wheel. The adsorption wheel 13 is slowly rotated by the servo motor 18, realizing a continuous moisture absorption and regeneration cycle, thereby humidifying or dehumidifying the fresh air without the need for an additional humidifier; the total heat exchanger 10 can exchange temperature and humidity between the fresh air and the exhaust air, pre-cooling or preheating the fresh air during the fresh air treatment process, and recovering energy from the exhaust air, further reducing the operating energy consumption of the fresh air oxygenation and purification device.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
