Description

Technical Field

[0001] This invention relates to an indoor air purification system, specifically an indoor air purification system that integrates gas detection modules with each air purification device to perform air pollution detection and coordinated control operations, so that the air pollution status of the indoor space is such that the number of suspended particles with a particle size between 1nm and 2.5um detected by multiple gas detection modules over 24 hours is the required output air pollution data for the indoor space, achieving the requirements of ZAPClean room levels 1 to 12. Prior Technology

[0002] Particulate matter refers to solid particles or droplets contained in gases. Due to their extremely small size, they can easily enter the lungs through nasal hairs, causing lung inflammation, asthma, or cardiovascular disease. If other pollutants adhere to particulate matter, the harm to the respiratory system will be further aggravated. In recent years, air pollution problems have become increasingly serious, especially the concentration of fine particulate matter (such as PM2.5), which is often too high. Monitoring the concentration of particulate matter has become increasingly important. However, because gases flow unpredictably with wind direction and volume, and most current gas quality monitoring stations for detecting particulate matter are fixed-point, it is impossible to accurately determine the current concentration of particulate matter in the surrounding environment.

[0003] Furthermore, modern people are paying increasing attention to the quality of the air in their surroundings. For example, gases such as carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), PM2.5, nitrogen monoxide, and sulfur monoxide, as well as particulate matter contained within these gases, can all affect human health when exposed to the environment, and in severe cases, even endanger life. Therefore, the quality of environmental air quality has become a major concern for many countries, and how to detect air quality and avoid or stay away from areas with poor air quality is a pressing issue.

[0004] Using a gas sensor to detect ambient gases is a viable way to determine the quality of gases. If it can also provide real-time detection information to alert people in the environment, allowing them to take immediate precautions or escape, thus avoiding harm to their health from harmful gases, then using a gas sensor to detect the surrounding environment is an excellent application.

[0005] Furthermore, indoor air quality is not easy to control. Besides outdoor air quality, indoor air conditioning conditions and pollution sources are the main factors affecting indoor air quality. A system that can intelligently and quickly detect indoor air pollution sources in various indoor areas can effectively remove indoor pollutants, creating a clean and safe breathing environment, and can monitor indoor air quality anytime, anywhere. Of course, if indoor areas can be strictly controlled according to "clean room" standards to prevent the introduction, generation, and retention of particles, and to control temperature and humidity within the required range, then the indoor environment can meet the clean room requirements for a safe breathing environment by differentiating the number of suspended particles in the air.

[0006] The air pollution detection in the current indoor air purification system involves a gas detector transmitting air pollution information, which is then transmitted via communication to a cloud computing service device. This data is stored in both the outdoor and indoor areas to form an air pollution database. Based on this data, the system intelligently performs calculations and comparisons, and then intelligently selects and issues a control command to the air purification device's fan to start and regulate the operation. This causes the indoor area to continuously generate internal circulation airflow, repeatedly diverting air pollution through the filter element for filtration and removal. This ensures that the air quality in the indoor area reaches the cleanliness level required for the number of suspended particulate matter.

[0007] Furthermore, the indoor air purification system achieves real-time monitoring and filtration of indoor air quality by deploying multiple indoor air purification devices and control devices in a coordinated manner. This ensures that the air pollution status of the indoor space is detected by multiple gas detection modules, and the number of suspended particles with a particle size between 1nm and 2.5um is accumulated over 24 hours. This meets the output air pollution data calibrated by the indoor space, achieving the requirements of ZAPClean room levels 1 to 12. This is the main research topic of this invention. Summary of the Invention

[0008] The main objective of this invention is to provide an indoor air purification system comprising a plurality of gas detection modules, a plurality of air purification devices, and at least one central control device. By electrically connecting the gas detection modules to each air purification device, air pollution detection and coordinated control operations are implemented. The central control device is connected to the gas detection modules, enabling transmission of control commands via a wired or wireless communication protocol to regulate the operation of the fans, airflow, and noise levels of the multiple air purification devices. This allows air pollution to be filtered through the filter elements of the multiple air purification devices, ensuring that the indoor air pollution level meets the requirements of ZAPClean room levels 1-12, based on the cumulative number of suspended particles (between 1nm and 2.5µm) detected by the gas detection modules over 24 hours.

The central control communication interface component of the group is connected via a wired or wireless communication protocol to provide a control command signal to the gas detection module to regulate the operation of the fans of multiple air purification devices, and to receive the air pollution data signal detected by the gas detection module and display it in real time; wherein, the air pollution status of the indoor area is the output air pollution data of the indoor area calibrated by the multiple gas detection modules based on the number of suspended particles with a particle size between 1nm and 2.5um detected in 24 hours, which meets the requirements of ZAPClean room level 1~12.

[0017] The aforementioned particulate sensing element 12a detects the particle size distribution (PM1, PM2.5, PM10) and concentration of suspended particulate matter contained in air pollution in an indoor area A or an outdoor area B. When the detected air pollution data for suspended particulate matter falls below a set safety value, the microcontroller 13 outputs several control signals when the detected air pollution data for suspended particulate matter exceeds a set safety value. For example, the set safety detection value for suspended particulate matter 2.5 (PM2.5) is a concentration less than 15 μg / m3. The temperature and humidity sensing element 12b detects the temperature and humidity of the air in indoor area A. When the detected air pollution data for temperature and humidity falls below a set safety value, the microcontroller 13 outputs several control signals when the detected air pollution data for temperature and humidity exceeds a set safety value. For example, the set safety value for temperature and humidity in indoor area A is to maintain the temperature in indoor area A within the range of 25°C ± 3°C and humidity within the range of 50% ± 10%. The gas sensing element 12c detects carbon dioxide (CO2) in the air. 2) When the concentration of carbon dioxide (CO2) is detected to be below a set safety value, the microcontroller 13 will output several control signals when the carbon dioxide (CO2) air pollution data exceeds a set safety value. For example, the set safety value of carbon dioxide (CO2) air pollution data in indoor area A must be maintained below 800 PPM.

[0018] The microcontroller 13 receives and processes air pollution data output from the sensing element assembly 12, and outputs several control signals. The air pollution data output by the sensing element assembly 12 is transmitted to the microcontroller 13 via serial communication (IIC) signals through electrical lines for processing. The control signals output by the microcontroller 13 include a Universal Asynchronous Receiver / Transmitter (UART) signal and a Universal Input / Output (GPI / O) signal. The UART signal is transmitted via electrical lines to the air purifier 2, the wireless communication component 14, and the central control communication interface component 15 for reception. The GPI / O signal is transmitted via electrical lines to the air purifier 2 for reception. It is noteworthy that, as shown in Figures 2A and 2B, the central control communication interface component 15 outputs a communication control line connected to a central control device 3 for communication protocol transmission. The communication protocol is a wired communication transmission using the RS485 communication protocol (solid transmission line portion in Figure 2A). Please refer to Figures 4A and 4B. The gas detection module 1 can be configured with an external power supply terminal, which can be directly plugged into the power interface in the indoor area A or the outdoor area B (as shown in Figures 1A and 1B, the gas detection module indicated by the number 1) to start operation and detect air pollution. Alternatively, as shown in Figure 4C, it can be a gas detection module without an external power supply terminal, which is directly connected to the internal electrical structure of the air purification device 2 (as shown in Figure 2A, the gas detection module 1).

[0019] Referring again to Figures 3A and 3C, the aforementioned air purification device 2, installed in indoor area A, includes a fan 21, a filter element 22, and a drive control component 23. A gas detection module 1 is directly integrated into the air purification device 2 and electrically connected. The gas detection module 1 can detect air pollution and output drive power and control signals. The gas detection module 1 is electrically connected to the fan 21 and the drive control component 23 (as shown in Figure 3C). Referring again to Figures 2B and 3C, the air purification device 2 further includes a relay 24 and a communication interface device 25. The relay 24 is electrically connected to the AC power input output by the power conversion component 11 and is also connected to the microcontroller 13 to output control signals (General Purpose Input / Output (GPIO)). The air purifier 2 outputs AC power to the drive control component 23 for power control and regulation. The communication interface device 25 connects to the 5V DC voltage required by the power conversion component 11 and cooperates with the microcontroller 13 to output control signals (Universal Asynchronous Receiver / Transmitter (UART) signals). It communicates with the drive control component 23 via a communication control line to control the fan speed of the air purifier 21, causing the fan 21 to start and draw air pollutants through the filter element 22 for filtration. It is noteworthy that in this embodiment, the communication protocol of the communication control line output by the air purifier 2 is an RS485 communication protocol. It is also noteworthy that in this embodiment, multiple air purifiers 2 can be implemented in this system. Each air purifier 2 includes an address encoder (not shown) for connection to the output control signal (Universal Input / Output (GP I / O) signal) line, enabling multiple air purifiers 2 to be serially connected and controlled.

[0020] Please refer to Figure 2B. The aforementioned central control device 3 is connected to the central control communication interface component 15 of the gas detection module 1 via a communication control line. Through the communication protocol connection, it provides control command signals to the microcontroller 13 to control the operation of multiple air purification devices 2, and receives air pollution data signals detected by the gas detection module 1 for real-time display.

[0021] Please refer to Figures 2B and 3C. The aforementioned cloud computing service device 4 receives air pollution data signals detected and output by the gas detection modules 1 of multiple air purification devices 2 via wireless communication through a router 5, stores them to form an air pollution data database, and intelligently calculates and compares the air pollution data to intelligently select and issue a control command. This command is then transmitted wirelessly through the router 5 to the gas detection modules 1 of the multiple air purification devices 2 for reception, and then transmitted to the drive control component 23 to control the fan 21 to start operation. The fan 21 is started under control and guides the air pollution through the filter element 22 for filtration, so that the air pollution state of the indoor area A meets the cleanroom level requirements according to the detection time.

[0022] Furthermore, the gas detection modules 1 of the aforementioned plurality of air purification devices 2 can also be connected to the central control and regulation device 3 via wired communication to receive air pollution data signals. The central control and regulation device 3 then transmits the air pollution data signals to the router 5 via wireless communication. The router 5 then transmits the air pollution data signals to the cloud computing service device 4 for storage, forming an air pollution data database. The cloud computing service device 4 intelligently calculates and compares the air pollution data and intelligently selects and issues control commands to the central control and regulation device 3 for communication connection. The central control and regulation device 3 then transmits the data to the gas detection modules 1 of the plurality of air purification devices 2 via wired communication connection for reception. The data is then transmitted to the drive control component 23 to control the fan 21 to start operation. The fan 21 is started under control and guides the air pollution through the filter element 22 for filtration, so that the air pollution status of indoor area A meets the cleanroom level requirements based on the detection time.

[0023] Under the Handshake communication protocol, if a wireless or wired communication connection is lost, the gas detection modules 1 of the plurality of air purification devices 2 can select either a working wired or wireless communication activation mechanism. The cloud computing service device 4 receives air pollution data through the working wired or wireless communication activation mechanism. The cloud computing service device 4 intelligently calculates and compares the air pollution data and intelligently selects to issue control commands. It connects through the working wired or wireless communication activation mechanism and transmits the data to the gas detection modules 1 of the plurality of air purification devices 2 for reception. The data is then transmitted to the drive control component 23 to control the fan 21 to start operation. The fan 21 is activated under control and guides air pollution through the filter element 22 for filtration, so that the air pollution status of indoor area A meets the cleanroom level requirements based on the detection time.

[0024] Furthermore, under the Handshake communication protocol, if both wireless and wired communication are lost, the gas detection modules 1 of the plurality of air purification devices 2 can autonomously calculate and compare the air pollution data they output, and send control commands to the drive control component 23 to start the fan 21. The fan 21, under control, draws air pollution through the filter element 22 for filtration, causing the air pollution state in indoor area A to approach zero, thus meeting the cleanroom level requirements. It is worth noting that the above-mentioned intelligent calculation includes artificial intelligence (AI) calculation and edge computing.

[0025] From the above description, the specific implementation of the indoor air purification system proposed by the present invention in indoor space A can be understood. The following describes the specific implementation of a plurality of air purification devices 2 in indoor space A. This air purification device 2 can be installed in indoor space A in a built-in or plug-in manner. If the air purification device 2 is installed in indoor space A in a built-in manner (as shown in Figures 1A and 1B), then at least one circulating air return channel C is provided in indoor space A, which is formed on the side of indoor space A by several partitions C1, and has a plurality of air intake ports C2 and a plurality of return air ports C3.

[0026] The air purification device 2 can be a gas exchanger 2a, which is installed in the recirculation air channel C of the indoor area A and corresponds to the air intake C2, and has a channel connection (not shown) to the outdoor area B for air exchange. The gas detection module 1 of the gas exchanger 2a receives control commands via wireless or wired communication and transmits them to the drive control component 23 to regulate the start-up of the fan 21. At least one gas detection module 1 is deployed in the outdoor area B and at least one gas detection module 1 is deployed in the indoor area A. The cloud computing service device 4 receives and stores the air pollution data of the indoor area A and the outdoor area B to form an air pollution data database. It intelligently calculates and compares the air pollution data of the indoor area A and the outdoor area B. When the air pollution data of the indoor area A is higher than that of the outdoor area B, the cloud computing service device 4 issues a control command via wireless or wired communication to the gas detection module 1 of the gas exchanger 2a. The control command is received and transmitted to the drive control component 23 to regulate the start-up of the fan 21, so that the gas in the outdoor area B is introduced into the indoor area A for ventilation. It is worth noting that the gas detection module 1 in both outdoor area B and indoor area A detects carbon dioxide (CO2) air pollution data. The CO2 air pollution data detected by the gas detection module 1 must be maintained below a set safety value of 800 PPM. When the air pollution data exceeds this set safety value, the gas exchanger 2a provides air from outdoor area B into indoor area A for ventilation. It is worth noting that the gas exchanger 2a can be a fresh air unit or a total heat exchanger.

[0027] Please refer to Figures 1A, 1B and 3C. The air purification device 2 can be a circulating filter device 2b, which is installed in the circulating return air channel C of the indoor area A and corresponds to the air intake C2. The air pollutants are filtered through the filter element 22 and discharged into the space of the indoor area A through the air intake C2. The gas detection module 1 of the circulating filter device 2b transmits air pollution data to the cloud computing service device 4 via wireless or wired communication. The cloud computing service device 4 receives the data and forms an air pollution data database. The database is then intelligently calculated and compared, and control commands are intelligently selected and issued. The gas detection module 1 receives the data via wireless or wired communication and transmits it to the drive control component 23 to start the fan 21 of the circulating filter device 2b. This draws air pollution through the filter element 22 and into the indoor space A. The air pollution status of the indoor space A is such that it meets the output air pollution data of multiple gas detection modules 1, which accumulates the number of PM2.5 inhaled suspended particles detected over 24 hours, and the indoor space required by one air purification device 2, thus achieving the requirements of ZAPClean room levels 1-12.

[0028] Please refer to Figures 1B, 1C, and 3C. The air purification device 2 can be a negative pressure exhaust fan 2c. The negative pressure exhaust fan 2c is installed in the kitchen unit A1 of indoor area A, and is located in the circulating return air duct C of indoor area A. It also has a duct connection (not shown) to outdoor area B to accelerate the discharge of air pollution from indoor area A to outdoor area B. The gas detection module 1 of the negative pressure exhaust fan 2c transmits air pollution data to the cloud computing service device 4, which receives and forms an air pollution data database. The database is then intelligently calculated and compared, and control commands are intelligently selected and issued. The gas detection module 1 receives the data via wireless or wired communication and transmits it to the drive control component 23 to activate the negative pressure exhaust fan 2c. This causes the air pollution to be filtered through the filter element 22, accelerating the discharge of air pollution from indoor area A to outdoor area B. It is worth noting that in this embodiment, the negative pressure exhaust fan 2c is located in front of the cooking equipment D, directly drawing out the air fumes so that the cook cannot smell the fumes and preventing the air fumes from spreading to other spaces such as the living room, but this is not the only limitation.

[0029] Please refer to Figures 1B, 1C, and 3C. The air purification device 2 can be a range hood 2d located in the kitchen unit A1 of indoor area A. The range hood 2d is installed in the circulating return air duct C of indoor area A and has a duct connection (not shown) to outdoor area B to accelerate the discharge of air pollution from indoor area A to outdoor area B. The gas detection module 1 of the range hood 2d transmits air pollution data to the cloud computing service device 4 to form an air pollution data database, and performs intelligent calculations and comparisons to intelligently select and issue control commands. The gas detection module 1 receives the data through wireless or wired communication and transmits it to the drive control component 23 to control the fan 21 of the range hood 2d to start operation, and guide the air pollution through the filter element 22 for filtration, so that the air pollution in indoor area A is accelerated to be discharged to outdoor area B.

[0030] Please refer to Figures 1B and 3C. The air purification device 2 can be a bathroom exhaust fan 2e, which is installed in the bathroom unit A2 of indoor area A. The bathroom exhaust fan 2e is installed in the circulating return air channel C of indoor area A and has a channel connection (not shown) to outdoor area B to accelerate the discharge of air pollution from indoor area A to outdoor area B. The gas detection module 1 of the bathroom exhaust fan 2e transmits the air pollution data to the cloud computing service device 4 to form an air pollution data database, and performs intelligent calculation and comparison to intelligently select and issue control commands. The gas detection module 1 receives the data through wireless or wired communication and transmits it to the drive control component 23 to start the fan 21 of the bathroom exhaust fan 2e, and guides the air pollution through the filter element 22 for filtration, so that the air pollution in indoor area A is accelerated to be discharged to outdoor area B, while simultaneously regulating the temperature and humidity of the bathroom unit A2 in indoor area A. It is worth noting that the temperature and humidity control is to maintain the temperature in the bathroom unit A2 of indoor space A within the range of 25°C±3°C and humidity of 50%±10%.

[0031] Please also refer to Figures 3A and 3B. The fan 21 of the air purification device 2 is started under control to draw air pollution through the filter element 22 for filtration. The filter element 22 can be an ultra-high efficiency filter (ULPA) or a high efficiency particulate air filter (HEPA) to adsorb chemical fumes, bacteria, dust particles and pollen contained in the air pollution, so as to achieve the effect of filtration and purification.

[0032] In this embodiment, the filter element 22 can be further combined with physical or chemical materials to provide a sterilization effect on air pollution. The airflow path of the fan 21 is as shown by the arrow. Therefore, as shown in Figure 3B, the filter element 22 incorporates a chemical method of passing through a decomposition layer to sterilize and remove air pollution. The decomposition layer can be activated carbon 22a, which removes organic and inorganic matter from the air pollution, as well as colored and odorous substances. Alternatively, the decomposition layer can be a chlorine dioxide cleaning agent 22b, which inhibits viruses and bacteria in the air pollution. It has an inhibition rate of over 99% against fungi, influenza A virus, influenza B virus, enterovirus, and norovirus, helping to reduce cross-infection of viruses. The decomposition layer can be a herbal protective layer 22c of ginkgo and Japanese sumac, which effectively resists allergies and destroys the surface proteins of influenza viruses (e.g., H1N1). The decomposition layer can be a silver ion 22d, which inhibits viruses, bacteria, and fungi introduced into the air pollution. The decomposition layer can be a zeolite 22e, which removes ammonia nitrogen, heavy metals, organic pollutants, E. coli, phenol, chloroform, and silver ion surfactants.

[0033] In some embodiments, the filter element 22 can also be combined with a photochemical method to sterilize and remove air pollution. The photochemical irradiation can be a photocatalyst unit consisting of a photocatalyst 22f and an ultraviolet lamp 22g. When the photocatalyst 22f is irradiated by the ultraviolet lamp 22g, it converts light energy into electrical energy, decomposing harmful substances in the air pollution and disinfecting it to achieve a filtration and sterilization effect. Alternatively, the photochemical irradiation can be a photoplasma unit consisting of a nanotube 22h. Irradiating the air pollution through the nanotube 22h decomposes oxygen and water molecules in the air into highly oxidizing photoplasma, forming an ion stream that destroys organic molecules, thus removing volatile organic compounds (VOCs) from the air pollution. VOCs and other gas molecules are decomposed into water and carbon dioxide, achieving the effect of filtration and sterilization. It is worth noting that in this embodiment, as shown in Figure 3D, the air purification device 2 is further provided with an ultraviolet lamp assembly 26. The ultraviolet lamp assembly 26 includes a relay 26a. The relay 26a outputs AC power input according to the power conversion component 11 and in conjunction with the output control signal (general input and output (GP I / O) signal) of the microcontroller 13 to provide AC power to a power switch 26b. The power switch 26b is connected to control the start and control of an ultraviolet lamp 22g. The ultraviolet lamp 22g is located on one side of the filter element 22 for sterilization of air pollutants.

[0034] In some embodiments, the filter element 22 can also be combined with a decomposition unit to chemically remove air pollutants through sterilization. The decomposition unit can be a negative ion unit 22i, which causes the particles contained in the introduced air pollutants to be positively charged and attached to the negatively charged particles, thereby achieving the effect of filtering and sterilizing the introduced air pollutants. The decomposition unit can be a plasma ion unit 22j, which causes the oxygen molecules and water molecules contained in the air pollutants to ionize into cations (H+) and anions (O2-) through plasma ions. After the substances with water molecules attached to the ions attach to the surface of viruses and bacteria, they will be converted into highly oxidizing active oxygen (hydroxyl, OH groups) under the action of chemical reaction, thereby taking away the hydrogen from the surface proteins of viruses and bacteria and oxidizing and decomposing them, so as to achieve the effect of filtering and sterilizing the introduced air pollutants.

[0035] Referring again to Figure 5, the aforementioned cloud computing service device 4 includes a wireless network cloud computing service module 41, a cloud control service unit 42, a device management unit 43, and an application unit 44. The wireless network cloud computing service module 41 receives air pollution data from the gas detection modules 1 in outdoor area B and indoor area A, and receives air pollution data from the gas detection modules 1 built into multiple air purification devices 2 (gas exchanger 2a, circulating filter 2b, negative pressure exhaust fan 2c, smoke exhaust fan 2d, bathroom exhaust fan 2e). It also transmits control commands. The wireless network cloud computing service module 41 receives air pollution data from indoor area A and outdoor area B and transmits it to the cloud control service unit 42 for storage, forming an air pollution data database. It performs intelligent calculations and compares the data with the air pollution data database, and sends control commands to the wireless network cloud computing unit 44. The computing service module 41 transmits control start operations to the devices (air purifier 2, central control and regulation device 3, gas exchanger 2a) via the wireless network cloud computing service module 41. The device management unit 43 receives communication information from multiple air purifiers 2 (gas exchanger 2a, circulating filter 2b, negative pressure exhaust fan 2c, smoke exhaust fan 2d, bathroom exhaust fan 2e) via the wireless network cloud computing service module 41 for user login management and device binding management. It can also provide device management information to the application unit 44 for system control management. The application unit 44 also displays and notifies users of the air pollution information obtained by the cloud control service unit 42, allowing users to understand the real-time status of air pollution removal through mobile phones or communication devices, and users to control the operation of the indoor air purification system through the application unit 44 of their mobile phones or communication devices.

[0036] As described above, this invention provides an indoor air purification system. In specific implementation, each indoor air purification device 2 is equipped with a gas detection module 1 to detect air pollution, transmit air pollution data, and receive control commands. This module is electrically connected to the drive control component 23 of the air purification device 2. The drive control component 23 regulates the operation of the fan 21 of the air purification device 2. The air pollution data output by the gas detection module 1 is received via wireless or wired communication. This utilizes the dual-mode (wired and wireless) communication to select the operational transmission mechanism. Under a monitoring mechanism that integrates wired and wireless communication protocols, the system autonomously selects either wired or wireless communication as the operational transmission mechanism to transmit the air pollution data output by the air pollution detection to the cloud computing service device 4. The cloud computing service device 4 then generates... The control command is fed back to the gas detection module 1 and transmitted to the electrical connection drive control component 23. The drive control component 23 then controls the fan 21 of the air purification device 2 to start operation, realizing a detection disconnection prevention mechanism that is required by wireless or wired communication. In addition, when the air pollution data detected by the gas detection module 1 is disconnected in both wired and wireless communication, the gas detection module 1 can autonomously calculate and compare the air pollution data and autonomously send a control command to the drive control component 23 of the air purification device 2 to start the fan 21. The fan 21 is started under control to guide the air pollution through the filter element 22 for filtration, so that the air pollution state of the indoor area A is the required output air pollution data of the indoor area space as specified by the gas detection module 1 based on the cumulative number of suspended particles with a particle size between 1nm and 2.5um detected in 24 hours, which meets the requirements of ZAPClean room level 1~12.

[0037] Furthermore, the indoor air purification system provided by this invention utilizes a cloud computing service device 4 to receive air pollution data from indoor area A and outdoor area B via wireless or wired communication, forming an air pollution data database. Based on this database, the system intelligently performs calculations and comparisons, and then intelligently selects and sends control commands to the fan 21 of the air purification device 2 to activate and regulate the operation. This causes indoor area A to continuously generate internal circulation airflow, repeatedly guiding air pollution through the filter element 22 for filtration and removal. In other words, the cloud computing service device 4 intelligently calculates the real-time number and cleanliness of suspended particulate matter in indoor area A and intelligently selects and sends control commands to multiple air purification devices. Set 2, and adjust the fan 21 of the air purification device 2 to start in a timely manner. Based on the real-time number and cleanliness of suspended particles, the fan 21 can be randomly adjusted in terms of air volume and start-up time, thereby improving the cleanliness efficiency of indoor area A and reducing the environmental noise of indoor area A. This creates an internal circulation directional airflow in indoor area A, which quickly guides air pollution through the filter element 22 multiple times for filtration and removal. This ensures that the air pollution status of indoor area A meets the output air pollution data required by the indoor space as specified by the number of suspended particles with a particle size between 1nm and 2.5um detected by multiple gas detection modules 1 over 24 hours, achieving the requirements of ZAPClean room level 1~12.

[0038] The aforementioned cleanroom class requirements state that ZAPCleanroom 1-12 is equivalent to ISO 1-9 cleanroom cleanliness. However, ZAPCleanroom 1-12 uses a different technical architecture than traditional ISO 1-9 cleanrooms, yet it achieves the same level of indoor air cleanliness. Traditional ISO 1-9 cleanrooms do not use sensors for real-time, 24 / 7 monitoring, so they operate at high speeds, accumulating data 24 / 7. This results in significant energy consumption and a noisy environment, making such a system unsuitable for general residential use.

[0039] The indoor air purification system of this invention belongs to the ZAPClean room level 1-12. This system utilizes multiple air purification devices 2 (gas exchanger 2a, circulating filter 2b, negative pressure exhaust fan 2c, smoke exhaust fan 2d, bathroom exhaust fan 2e) with built-in gas detection modules 1 and a cloud computing service device 4 to form an intelligent interconnected system. The gas detection modules 1, both external and internal, detect PM2.5 concentration / particle count, carbon dioxide (CO2), carbon monoxide (CO), formaldehyde, methane, toluene, volatile organic compounds (TVOC), ozone (O3), nitric oxide (NO), nitrogen dioxide (NO2), and sulfur dioxide (SO2). Radon (Rn-222), bacteria, and fungi can be transmitted via wired or wireless communication to a cloud computing service device 4. The intelligent computing selects and provides control command signals to the gas detection module 1 of multiple air purification devices 2 to regulate the start-up, airflow speed, and noise level of the fan 21, thereby achieving the ZAPClean room system that provides quiet and high-efficiency operation.
