Description

Technical Field

[0001] This invention relates to the technical field of fresh air dehumidification systems, and in particular to a unidirectional flow fresh air dehumidification system with integrated intelligent exhaust. Background Technology

[0002] Currently, most fresh air systems on the market are bulky, making it difficult to replace filters after ceiling installation. This is especially true when the dehumidification system malfunctions, making repairs even more challenging. Furthermore, some products are installed in basements, where traditional products cannot effectively drain condensate.

[0003] Traditional fresh air systems can only exchange air in one direction and cannot be linked to dehumidification. Humidity control relies on a separate dehumidifier, which takes up space and consumes a lot of energy.

[0004] Some use integrated equipment, most of which adopt a bidirectional flow design, resulting in relatively complex structures and high noise levels, and making filter replacement difficult;

[0005] Regarding intelligent control: Traditional products use a single sensor (only monitoring PM2.5 or CO2), which cannot control multiple parameters in a coordinated manner.

[0006] Because traditional equipment has many problems, there are many directions and room for improvement.

[0007] To improve the above problems, the main issue is that existing fresh air systems have limited functionality and cannot efficiently combine dehumidification and purification. Utility Model Content

[0008] To address the aforementioned technical problems and shortcomings—specifically, how to solve the issue of existing fresh air systems having limited functionality and being unable to efficiently link dehumidification and purification—this invention provides a unidirectional flow fresh air dehumidification system with integrated intelligent exhaust ventilation.

[0009] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0010] A unidirectional flow fresh air dehumidification system with integrated intelligent exhaust includes a fresh air purification and dehumidification unit, an exhaust fan, a branch box, an air outlet elbow, an air duct, and a controller. The fresh air purification and dehumidification unit has an outdoor fresh air inlet and an indoor return air inlet. A first air valve is installed at the outdoor fresh air inlet, and a second air valve is installed at the indoor return air inlet. A filter module, a dehumidification module, an air supply module, a disinfection and sterilization module, and an indoor fresh air outlet are arranged sequentially on the rear side of the outdoor fresh air inlet and the indoor return air inlet.

[0011] The indoor fresh air outlets are distributed into multiple fresh air outlets through a branch box, and the fresh air outlets are connected through air ducts or air vent elbows;

[0012] Exhaust fans have indoor air inlets and outdoor air outlets, used to exhaust indoor air to the outside;

[0013] The integrated fresh air purification and dehumidification unit and the exhaust fan are connected to the same controller via wiring and are controlled by the controller.

[0014] Preferably, the controller includes a PM2.5 sensor, a carbon dioxide sensor, a temperature and humidity sensor, and a TVOC sensor, and the controller is used to monitor room air quality indicators in real time through the sensors.

[0015] Preferably, the filtration module includes a coarse filter, a HEPA filter, and an activated carbon adsorption layer, which form a stacked structure.

[0016] Preferably, the dehumidification module includes a condenser, an evaporator, a compressor, and a drain lift pump. The compressor connects to the condenser and the evaporator to provide working power. The drain lift pump collects and discharges accumulated water. An inspection port is provided on the side of the outer casing of the integrated fresh air purification and dehumidification unit.

[0017] Preferably, the evaporator and condenser of the dehumidification module are arranged side by side, and the surface of the evaporator is coated with an antibacterial coating.

[0018] Preferably, the controller communicates with the outside world via a 485 communication module or a WIFI module.

[0019] Preferably, the branch box is integrated inside the fresh air purification and dehumidification unit or is set independently outside the fresh air purification and dehumidification unit.

[0020] In summary, the present invention provides the following beneficial technical effects:

[0021] The integrated fresh air purification and dehumidification unit can filter and dehumidify outdoor air. The air circulation process is as follows: outdoor air enters through the outdoor fresh air inlet, and the first and second air valves can be independently controlled to open and close, realizing the function of outdoor fresh air or indoor return air circulation. When the air passes through the filtration module, dust is removed, and when it passes through the dehumidification module, moisture is removed. The air supply module provides airflow, and the disinfection and sterilization module sterilizes the air. Finally, the fresh air exits through the indoor fresh air outlet. In order to deliver the air to more rooms, a branch box is used for distribution.

[0022] The indoor air circulation process: Indoor air is transported to the outside through the exhaust fan; the fresh air purification and dehumidification unit and the exhaust fan are connected to the same controller through the circuit. Through this controller, intelligent control can be performed, which can switch the action of the first air valve and the second air valve, and can also control the operation of electrical equipment.

[0023] This solution combines dehumidification, fresh air, disinfection, and exhaust functions to provide fresh air and a comfortable humidity environment around the clock. Attached Figure Description

[0028] The following specific examples illustrate the implementation of this invention. Those skilled in the art can easily understand other advantages and effects of this invention from the content disclosed in this specification. This invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be changed at will, and the layout of the components may also be more complex.

[0030] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] Example:

[0032] This invention discloses a unidirectional flow fresh air dehumidification system with integrated intelligent exhaust ventilation, as described in the following embodiments. Figure 1 and Figure 2As shown, the system includes a fresh air purification and dehumidification integrated unit 1, an exhaust fan 2, a branch box 3, an air outlet elbow 4, an air duct 5, and a controller 6.

[0033] First, let's introduce the integrated fresh air purification and dehumidification unit 1. This unit has an outdoor fresh air inlet 11 and an indoor return air inlet 12. Multiple outdoor fresh air inlets can be selected according to actual needs, as a first air valve 13 is installed at the outdoor fresh air inlet 11, and a second air valve 14 is installed at the indoor return air inlet 12. Therefore, the first air valve 13 and the second air valve 14 can be independently controlled by rotating to open individually or simultaneously. The operating mode can be freely switched, allowing for either fresh air circulation or indoor air circulation.

[0034] A filter module 15, a dehumidification module 16, an air supply module 17, a disinfection and sterilization module 18, and an indoor fresh air outlet 19 are sequentially installed on the rear side of the outdoor fresh air inlet 11 and the indoor return air inlet 12.

[0035] Regarding the filter module 15, in a preferred example, the filter module 15 includes a coarse filter, a HEPA filter, and an activated carbon adsorption layer, which form a stacked structure. The coarse filter, HEPA filter, and activated carbon adsorption layer can be purchased commercially; this solution uses a stacked assembly. Through the filter module 15, the dual filtration of the coarse filter and the high-efficiency HEPA filter can remove more than 99% of PM2.5 and other inhalable particulate matter from the air. During the internal circulation function, it works in conjunction with the activated carbon adsorption layer (filter) to adsorb indoor odors. The filter module 15 is mounted on the integrated fresh air purification and dehumidification unit 1 in a pull-out manner on the sheet metal part of the housing, and can also be replaced through the inspection port 10, which is very convenient.

[0036] Regarding the dehumidification module 16, a preferred example is... Figure 1 and Figure 2 The dehumidification module 16 includes a condenser 161, an evaporator 162, a compressor 163, and a drain lift pump 164. The dehumidification module 16 can be commercially available, and the dehumidification principle is existing technology. In this solution, the drain lift pump 164 is added to allow for faster drainage of accumulated water. The compressor 163 connects the condenser 161 and evaporator 162 to provide power, while the drain lift pump 164 collects and drains accumulated water. An inspection port 10 is provided on the side of the casing of the integrated fresh air purification and dehumidification unit 1, making maintenance of the dehumidification module 16 very convenient. The evaporator 162 and condenser 161 of the dehumidification module 16 are arranged side-by-side, and the surface of the evaporator 162 is coated with an antibacterial coating. The antibacterial coating can be made from commercially available materials. The compressor 163's condensation dehumidification technology quickly reduces indoor humidity, prevents mold growth, and protects furniture, clothing, and other items from moisture damage.

[0037] Regarding the air supply module 17, the fan used can be controlled by the controller 6 and provides airflow.

[0038] Regarding the disinfection and sterilization module 18, in one example, ultraviolet light can be used for sterilization. In a second example, water ion sterilization can be used.

[0039] Next, the indoor fresh air outlet 19 is distributed into multiple fresh air outlets through the branch box 3, and the fresh air outlets are connected through the air duct 5 or the air outlet elbow 4.

[0040] The exhaust fan 2 has an indoor air inlet 21 and an outdoor air outlet 22, used to exhaust indoor air to the outside. The fresh air purification and dehumidification integrated unit 1 and the exhaust fan 2 are connected to the controller 6 via wiring and are controlled by the controller 6.

[0041] When continuous ventilation is in operation: Through the intelligent combination of fresh air and exhaust air, filtered fresh outdoor air is continuously introduced and indoor stale air is removed, preventing the accumulation of carbon dioxide, odors, etc., ensuring fresh indoor air and improving living comfort.

[0042] Regarding controller 6, it includes a PM2.5 sensor, a carbon dioxide sensor, a temperature and humidity sensor, and a TVOC sensor. Controller 6 is used to monitor indoor air quality indicators in real time through these sensors. Controller 6 communicates with external devices via a RS-485 communication module or a Wi-Fi module.

[0043] Intelligent control is achieved through controller 6: Controller 6 has built-in carbon dioxide, PM2.5, TVOC, and temperature / humidity sensors to monitor indoor air quality in real time and automatically adjust the fresh air and exhaust air volumes to ensure air circulation. Controller 6 receives signals and automatically adjusts its operating mode according to the indoor environment, making it simple, convenient, and labor-saving. This solution offers multiple operating modes: fresh air mode, dehumidification mode, internal circulation mode, and automatic switching mode, achieving intelligent management. It has 485 communication capabilities and can be integrated into a whole-house smart home system. It can also be remotely controlled via WiFi. The product is modular and easy to maintain. The software functions are only described in detail and are not the subject of this application; the main purpose is to disclose a hardware function of controller 6 to facilitate understanding of the overall solution.

[0044] The controller 6 includes a control circuit board 61 and an operation control board 62, which can communicate with each other. The operation control board 62 can be a touch screen or an operation screen, or other similar circuit devices.

[0045] In other implementation processes, the branch box 3 can also be integrated inside the fresh air purification and dehumidification unit 1 or set independently outside the fresh air purification and dehumidification unit 1.

[0046] Therefore, it is evident that physical separation between independent exhaust ducts and fresh air ducts is more conducive to home installation, after-sales maintenance, and repair.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the scope of the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent changes made to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
