Description

Technical Field

[0001] The present invention relates to an indoor air purification system, in particular to an indoor air purification system that combines a gas detection module on each air purification device to perform air pollution detection and collaborative regulation operations, so that the air pollution state in the indoor field is the output air pollution data calibrated by the detection prediction time of multiple gas detection modules, meeting the clean room grade requirements. Background Art

[0002] Suspended particles refer to solid particles or liquid droplets contained in gas. Due to their very fine particle size, they are easily inhaled into the human lungs through the nasal hairs in the nasal cavity, thus causing inflammation of the lungs, asthma, or cardiovascular diseases. If other pollutants adhere to the suspended particles, it will further aggravate the harm to the respiratory system. In recent years, the problem of gas pollution has become increasingly serious. Especially, the concentration data of fine suspended particles (such as PM2.5) are often too high, and the monitoring of the concentration of gas suspended particles has gradually attracted attention. However, since gas flows unstably with the wind direction and wind volume, and most of the current gas quality monitoring stations for detecting suspended particles are fixed-point, it is simply impossible to confirm the current concentration of suspended particles in the surrounding area.

[0003] Moreover, modern people pay more and more attention to the gas quality in their living surroundings. For example, gases such as carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM2.5, nitrogen monoxide, sulfur monoxide, etc., and even the particles contained in the gas will expose in the environment and affect human health, and in severe cases, even endanger life. Therefore, the quality of environmental gas has attracted the attention of various countries. How to detect gas quality to avoid and stay away from areas with poor gas quality is a current important topic.

[0004] To confirm the quality of gas, it is feasible to use a gas sensor to detect the surrounding environmental gas. If it can also provide detection information immediately and alert people in the environment, enabling them to prevent or escape immediately and avoid being harmed by the gas in the environment and affecting human health, using a gas sensor to detect the surrounding environment can be said to be a very good application.

[0005] Moreover, it is not easy to control the indoor air quality. Besides the outdoor air quality, the indoor air-conditioning conditions and pollution sources are the main factors affecting the indoor air quality. It is possible to quickly and intelligently detect indoor air pollution sources in various indoor fields, effectively remove indoor air pollution to form a clean and safe breathing gas state, and can monitor the indoor air quality instantly at any time. Of course, if the indoor field can strictly control the concentration of airborne particles according to the standards of a "clean room", strive to avoid the introduction, generation and retention of particles, and control its temperature and humidity within the required range. That is to say, the indoor field differentiates their grades according to the number of suspended particles in the air, meeting the clean room requirements of a safe breathing indoor field.

[0006] Currently, for the air pollution detection of the provided indoor air purification system, the gas detector detects and transmits the air pollution information, and then through communication, it is transmitted to the cloud computing service device to receive the air pollution data of the outdoor field and the indoor field and store it to form a database of air pollution data. And based on the intelligent operation and comparison of the air pollution data, an intelligent selection is made to send a control instruction to the fan of the air purification device to start the regulation operation, so that an internal circulation directional airflow is continuously generated in the indoor field, and the air pollution is drained through the filter element multiple times for filtration and removal, so that the gas state of the indoor field can reach the clean room level through the cleanliness specification of the number of suspended particulate particles.

[0007] Moreover, the indoor air purification system achieves instant monitoring of the indoor air quality and instant processing of filtration and purification through the coordinated regulation of multiple indoor air purification devices and control devices, promoting the indoor air pollution to approach zero cleanliness and forming a breathable gas state indoors. This is the main research topic developed in this invention. Summary of the Invention

[0008] The main object of the present invention is to provide an indoor air purification system, including multiple gas detection modules, multiple air purification devices, and at least one central control and regulation device. By combining and setting gas detection modules on each air purification device and electrically connecting them, air pollution detection and coordinated regulation operations are implemented. And the central control and regulation device is connected to the gas detection module, and through a handshaking communication protocol of wired communication or wireless communication, an activation mechanism is selected to transmit and connect to provide a control instruction signal to the gas detection module to regulate the start operation, air volume and noise of the fans of multiple air purification devices, so that the air pollution is filtered through the filter elements of multiple air purification devices, and the air pollution state of the indoor field is output as air pollution data calibrated by multiple gas detection modules at the predicted time, meeting the clean room level requirements.

[0009] To achieve the above object, the present invention provides an indoor air purification system, comprising: a plurality of gas detection modules for detecting air pollution, generating air pollution data, and processing and outputting several control signals through operation; a plurality of air purification devices disposed in an indoor area, mainly including a fan, a filter element, and a drive control component, and the gas detection module is built in and electrically connected to the drive control component to control the start, air volume, and noise level of the fan, so that the fan is controlled to start and draw the air pollution through the filter element for filtration; at least one central control device connected to the central control communication interface component of the gas detection module, and providing a control command signal to the gas detection module to control the operation of the fan of the plurality of air purification devices through a handshake communication protocol of wired communication or wireless communication, and receiving the air pollution data signal detected by the gas detection module for immediate display; wherein, the air pollution state of the indoor area is the output air pollution data calibrated by the plurality of gas detection modules at the detected prediction time, meeting the requirements of the clean room grade.

The communication interface device 25 is connected and input according to the 5V required DC voltage output by the power conversion component 11 and cooperates with the output regulation signal (universal asynchronous receiver / transmitter (UART) signal) of the microcontroller 13 to input, and is connected to the drive control component 23 through a communication control line for communication transmission connection to regulate the wind speed control of the fan 21 of the air purification device 2, so that the fan 21 is controlled to start and drain air pollution through the filter element 22 for filtration. It should be noted that in this embodiment, the communication protocol of the communication control line output by the air purification device 2 is an RS485 communication protocol. It should be noted that in this embodiment, multiple air purification devices 2 can be implemented in this system. Each air purification device 2 includes an address encoder (not shown) for connection to the line outputting the regulation signal (general-purpose input and output (GPIO) signal), so that multiple such air purification devices 2 can be serially connected and regulated.

[0086] Please refer to Figure 2B shown. The above-mentioned central control and regulation device 3 is connected to the central control communication interface component 15 of the gas detection module 1 through a communication control line, and provides a control command signal to the microcontroller 13 through a communication protocol connection to regulate the operation of multiple air purification devices 2, and receives the air pollution data signal detected by the gas detection module 1 for immediate display.

[0087] Please refer to Figure 2B and Figure 3CAs shown, the above-mentioned cloud computing service device 4 wirelessly communicates through a router 5 to receive the air pollution data signals detected and output by the gas detection modules 1 of multiple air purification devices 2, and stores them to form a database of air pollution data. Moreover, the cloud computing service device 4 performs intelligent calculation and comparison based on the air pollution data, and then intelligently selects to send a control instruction to be connected through wireless communication via the router 5, and then transmits it to the gas detection modules 1 of multiple air purification devices 2 for reception, and then transmits it to the drive control component 23 to regulate the start and operation of the fan 21. The fan 21 is controlled to start and draw air pollution through the filter element 22 for filtration, so that the air pollution state of the indoor field A is calibrated at the detection time, meeting the cleanroom grade requirements.

[0088] Furthermore, the gas detection modules 1 of the above-mentioned multiple air purification devices 2 can also be connected to the central control and regulation device 3 through wired communication to receive air pollution data signals. And the central control and regulation device 3 then transmits the air pollution data signals through wireless communication to be received by the router 5, and then the router 5 receives and transmits the air pollution data signals to the cloud computing service device 4 for storage to form a database of air pollution data. Moreover, the cloud computing service device 4 performs intelligent calculation and comparison based on the air pollution data, and then intelligently selects to send a control instruction to communicate with the central control and regulation device 3. The central control and regulation device 3 then transmits it through wired communication connection to the gas detection modules 1 of multiple air purification devices 2 for reception, and then transmits it to the drive control component 23 to regulate the start and operation of the fan 21. The fan 21 is controlled to start and draw air pollution through the filter element 22 for filtration, so that the air pollution state of the indoor field A is calibrated at the detection time, meeting the cleanroom grade requirements.

[0089] Under the Handshake communication protocol, if there is a disconnection in wireless communication or wired communication, the gas detection modules 1 of the above-mentioned multiple air purification devices 2 can regulate and select an alternative startup mechanism for operable transmission of wired communication or wireless communication. And the cloud computing service device 4 receives the air pollution data through the alternative startup mechanism of operable transmission of wired communication or the wireless communication. Moreover, the cloud computing service device 4 performs intelligent calculation and comparison based on the air pollution data, and then intelligently selects to send a control instruction, and connects through the alternative startup mechanism of operable transmission of wired communication or wireless communication, and then transmits it to the gas detection modules 1 of multiple air purification devices 2 for reception, and then transmits it to the drive control component 23 to regulate the start and operation of the fan 21. The fan 21 is controlled to start and draw air pollution through the filter element 22 for filtration, so that the air pollution state of the indoor field A is calibrated at the detection time, meeting the cleanroom grade requirements.

[0090] Moreover, under the Handshake communication protocol, when the gas detection modules 1 of multiple air purification devices 2 are disconnected from both wireless and wired communications, the air pollution data detected by the gas detection modules 1 can independently calculate and compare the air pollution data, and issue a control instruction to be transmitted to the drive control component 23 to regulate the start-up operation of the fan 21. The fan 21 is controlled to start and drain the air pollution through the filter element 22 for filtration, so that the air pollution gas state in the indoor area A approaches zero, meeting the requirements of the clean room grade. It should be noted that the above intelligent operations include artificial intelligence (AI) operations and edge operations.

[0091] From the above description, the specific implementation manner of an indoor air purification system proposed by the present invention in the indoor area A can be understood. The following describes multiple air purification devices 2 specifically implemented in the indoor area A. This air purification device 2 can be set in the indoor area A in an embedded (Build-in) or plug-in (Plug-in) manner. If the air purification device 2 is set in the indoor area A in an embedded (Build-in) manner (as Figure 1A and Figure 1B shown), therefore, at least one circulating return air channel C is set in the indoor area A, which is formed by being surrounded and isolated by several partitions C1 on the side of the indoor area A, and is provided with multiple air inlet ports C2 and multiple air return ports C3.

[0092] The air purification device 2 can be a gas exchanger 2a. The gas exchanger 2a is arranged in the circulating return air duct C of the indoor field A, corresponding to the air intake C2, and has a channel to communicate with the outdoor field B (not shown) for ventilation. The gas detection module 1 of the gas exchanger 2a receives control instructions through wireless or wired communication and transmits them to the drive control component 23 to regulate the start and operation of the fan 21. There is at least one gas detection module 1 arranged in the outdoor field B and at least one gas detection module 1 arranged in the indoor field A. The cloud computing service device 4 receives the air pollution data of the indoor field A and the outdoor field B for storage to form a database of air pollution data, and intelligently calculates and compares the air pollution data of the indoor field A and the outdoor field B. When the air pollution data of the indoor field A is higher than that of the outdoor field B, the cloud computing service device 4 issues a control instruction through wireless or wired communication to the gas detection module 1 of the gas exchanger 2a. The gas detection module 1 receives the control instruction and transmits it to the drive control component 23 to regulate the start and operation of the fan 21, so that the gas in the outdoor field B is introduced into the indoor field A for ventilation. It should be noted that the gas detection modules 1 in the outdoor field B and the indoor field A detect the air pollution data of carbon dioxide (CO2). The air pollution data of carbon dioxide (CO2) detected by the gas detection module 1 must be maintained below a set safety value of 800 PPM. When the air pollution data exceeds the set safety value, the gas exchanger 2a provides the gas in the outdoor field B to be introduced into the indoor field A for ventilation. It should be noted that the gas exchanger 2a can be a fresh air fan or a total heat exchanger.

[0094] Please refer to Figure 1B 、 Figure 1C as shown in Figure 3CAs shown, the air purification device 2 can be a negative pressure exhaust fan 2c. The negative pressure exhaust fan 2c is arranged at the position of the kitchen unit A1 in the indoor area A, and the negative pressure exhaust fan 2c is arranged in the circulating return air duct C of the indoor area A, and has a channel communicating (not shown) with the outdoor area B to accelerate the discharge of air pollutants in the indoor area A to the outside of the outdoor area B. The gas detection module 1 of the negative pressure exhaust fan 2c transmits air pollution data externally to the cloud computing service device 4 for reception to form a database of air pollution data, and performs intelligent calculation and comparison, and then intelligently selects to issue a control instruction. The gas detection module 1 receives it through wireless or wired communication, and then transmits it to the drive control component 23 to regulate the start-up operation of the negative pressure exhaust fan 2c, and guides the air pollutants to be filtered through the filter element 22, so as to accelerate the discharge of air pollutants in the indoor area A to the outside of the outdoor area B. It should be noted that in the embodiment of this case, the negative pressure exhaust fan 2c is arranged in front of the cooking device D to directly suck the air pollutants out, so that the cook cannot smell the cooking fumes and prevent the air pollutants from spreading to other spaces such as the living room space, but it is not limited to this.

[0095] Please refer to Figure 1B 、 Figure 1C as shown in Figure 3C As shown in and, the air purification device 2 can be a range hood 2d. The range hood 2d is arranged at the position of the kitchen unit A1 in the indoor area A, and the range hood 2d is arranged in the circulating return air duct C of the indoor area A, and has a channel communicating (not shown) with the outdoor area B to accelerate the discharge of air pollutants in the indoor area A to the outside of the outdoor area B. The gas detection module 1 of the range hood 2d transmits air pollution data externally to the cloud computing service device 4 for reception to form a database of air pollution data, and performs intelligent calculation and comparison, and then intelligently selects to issue a control instruction. The gas detection module 1 receives it through wireless or wired communication, and then transmits it to the drive control component 23 to regulate the start-up operation of the fan 21 of the range hood 2d, and guides the air pollutants to be filtered through the filter element 22, so as to accelerate the discharge of air pollutants in the indoor area A to the outside of the outdoor area B.

[0096] Please refer to Figure 1B as shown in Figure 3CAs shown, the air purification device 2 can be a bathroom exhaust fan 2e, which is installed at the position of the bathroom unit A2 in the indoor area A. The bathroom exhaust fan 2e is installed in the circulating return air duct C of the indoor area A and has a channel connection (not shown) to the outdoor area B to accelerate the discharge of indoor air pollutants to the outside of the outdoor area B. The gas detection module 1 of the bathroom exhaust fan 2e transmits the air pollutant data to the cloud computing service device 4 for receiving and forming a database of air pollutant data, and performs intelligent calculation and comparison, and then intelligently selects to issue a control instruction. The gas detection module 1 receives it through wireless or wired communication and then transmits it to the drive control component 23 to control the start and operation of the fan 21 of the bathroom exhaust fan 2e. The air pollutants are drained and filtered through the filter element 22, so that the air pollutants in the indoor area A are accelerated and discharged to the outdoor area B, and at the same time, the temperature and humidity of the bathroom unit A2 in the indoor area A are regulated. It should be noted that the temperature and humidity regulation is to maintain the temperature in the bathroom unit A2 of the indoor area A within the range of 25°C ± 3°C and the humidity within the range of 50% ± 10%.

[0097] Please also refer to Figure 3A 、 Figure 3B As shown, when the fan 21 of the above-mentioned air purification device 2 is controlled to start and drain the air pollutants through the filter element 22, the filter element 22 can be of the ultra-high efficiency particulate air (ULPA) grade or the high efficiency particulate air (HEPA) filter, which adsorbs chemical smog, bacteria, dust particles and pollen contained in the air pollutants, so as to achieve the effect of filtering and purifying the introduced air pollutants.

[0098] In this embodiment, physical or chemical property materials can be further combined on the filter element 22 of the present case to provide a bactericidal effect on the passing air pollutants, and the air flow path direction of the fan 21 is the direction shown by the arrow. Therefore, as Figure 3B shown, the filter element 22 is combined with a chemical method of coating a decomposition layer to sterilize and remove the passing air pollutants. The decomposition layer can be an activated carbon 22a, which removes organic and inorganic substances in the air pollutants and removes colored and odorous substances. The decomposition layer can be a clean factor 22b of chlorine dioxide, which can inhibit viruses, bacteria, fungi, influenza A virus, influenza B virus, enterovirus, and norovirus in the air pollutants by more than 99%, helping to reduce the cross-infection of viruses. The decomposition layer can be a herbal care layer 22c of ginkgo and Japanese sumac, which can effectively resist allergies and destroy the surface proteins of influenza viruses (such as H1N1). The decomposition layer can be a silver ion 22d, which can inhibit viruses, bacteria, and fungi in the introduced air pollutants. The decomposition layer can be a zeolite 22e, which can remove ammonia nitrogen, heavy metals, organic pollutants, Escherichia coli, phenol, chloroform, and silver ion surfactants.

[0099] In some embodiments, the filter element 22 can also be combined with a chemical method of light irradiation to sterilize and remove air pollutants. The light irradiation is a photocatalyst unit including a photocatalyst 22f and an ultraviolet lamp 22g. When the photocatalyst 22f is irradiated by the ultraviolet lamp 22g, it can convert light energy into electrical energy, decompose harmful substances in the air pollutants and disinfect, so as to achieve the effect of filtering and sterilization. The light irradiation can be a photo-plasma unit of a nano-light tube 22h. By irradiating the introduced air pollutants through the nano-light tube 22h, the oxygen molecules and water molecules in the air pollutants are decomposed into highly oxidizing photo-plasmas, forming an ion flow with the ability to destroy organic molecules, and decomposing gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOCs) in the air pollutants into water and carbon dioxide, achieving the effect of filtering and sterilization. It should be noted that, in this embodiment, as Figure 3D shown, 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 an alternating current power supply to a power switch 26b according to the alternating current (AC) power supply input output by the power conversion component 11 and in cooperation with the output control signal (general-purpose input and output (GPIO) signal) of the microcontroller 13, and the power switch 26b is connected to control the start and regulation of an ultraviolet lamp 22g. The ultraviolet lamp 22g is arranged on one side of the filter element 22 to sterilize the passing air pollutants.

[0100] In some embodiments, the filter element 22 can also be combined with a chemical method of a decomposition unit to sterilize and remove air pollutants. The decomposition unit can be a negative ion unit 22i, so that the particles contained in the introduced air pollutants carry a positive charge and adhere to the negatively charged filter element, achieving the effect of filtering and sterilizing the introduced air pollutants. The decomposition unit can be a plasma ion unit 22j. Through the plasma ions, the oxygen molecules and water molecules contained in the air pollutants are ionized to generate cations (H+) and anions (O2-). After the substances with water molecules attached around the ions adhere to the surfaces of viruses and bacteria, under the action of chemical reactions, they will be converted into highly oxidizing reactive oxygen species (hydroxyl, OH radicals), which will then take away the hydrogen of the proteins on the surfaces of viruses and bacteria and oxidize and decompose them, so as to achieve the effect of filtering and sterilizing the introduced air pollutants.

[0101] Please refer to Figure 5As shown, the above-mentioned 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 program unit 44. Among them, the wireless network cloud computing service module 41 receives the air pollution data information of the gas detection module 1 in the outdoor field B and the indoor field A, receives the air pollution data information communication of the built-in gas detection module 1 of multiple air purification devices 2 (gas exchanger 2a, circulation filtration device 2b, negative pressure exhaust fan 2c, smoke exhaust machine 2d, bathroom exhaust fan 2e), and transmits control instructions. The wireless network cloud computing service module 41 receives the air pollution data information of the indoor field A and the outdoor field B and transmits it to the cloud control service unit 42 for storage to form a database of air pollution data, and implements intelligent calculation and comparison through the air pollution data database, and issues control instructions to be transmitted to the wireless network cloud computing service module 41, and then transmitted to the devices (air purification device 2, central control regulation device 3, gas exchanger 2a) through the wireless network cloud computing service module 41 for control startup operation. The device management unit 43 receives the communication information of multiple air purification devices 2 (gas exchanger 2a, circulation filtration device 2b, negative pressure exhaust fan 2c, smoke exhaust machine 2d, bathroom exhaust fan 2e) through the wireless network cloud computing service module 41 for user login management and device binding management, and can provide the device management information to the application program unit 44 for system control management. The application program unit 44 also displays and notifies the air pollution information obtained through the cloud control service unit 42, enabling the user to understand the immediate status of air pollution removal through a mobile phone or communication device, and enabling the user to control the operation of the indoor air purification system through the application program unit 44 of the mobile phone or communication device.

[0102] As can be seen from the above description, the present invention provides an indoor air purification system. Specifically, a gas detection module 1 is provided on each indoor air purification device 2 to detect air pollution, transmit air pollution data, and receive control instructions and be electrically connected to the drive control component 23 of the air purification device 2. The drive control component 23 regulates the start and operation of the fan 21 of the air purification device 2, and the output of the air pollution data by the gas detection module 1 is transmitted and received through wireless or wired communication. It can be realized by using a dual mode of wired communication and wireless communication to select an operable transmission communication mechanism. Under the monitoring mechanism of the actual handshaking communication protocol for wired communication and wireless communication, it independently judges and selects an operable wired communication for transmission communication or an operable wireless communication for transmission communication to transmit the air pollution data output by the air pollution detection to the cloud computing service device 4. Then, the cloud computing service device 4 generates a control instruction and feeds it back to the gas detection module 1 for transmission to the electrically connected drive control component 23, and the drive control component 23 regulates the start and operation of the fan 21 of the air purification device 2, realizing a detection disconnection prevention mechanism measure for wireless or wired communication. In addition, in the case of double disconnection communication of wired communication and wireless communication for the air pollution data output by the detection of the gas detection module 1, the gas detection module 1 can independently calculate and compare the air pollution data, and independently send a control instruction to the drive control component 23 of the air purification device 2 to regulate the start and operation of the fan 21, so that the fan 21 is controlled to start and drain the air pollution through the filter element 22 for filtration, so that the air pollution state of the indoor field A is calibrated by the detection time, meeting the clean room grade requirements.

[0103] In addition, for the indoor air purification system provided by the present invention, the cloud computing service device 4 receives the air pollution data of the indoor field A and the outdoor field B through wireless or wired communication and stores it to form a database of air pollution data. And based on the intelligent calculation and comparison of the database of air pollution data, it intelligently selects and issues a control instruction to the fan 21 of the air purification device 2 to start the regulation operation, so that an internal circulation directional air flow is continuously generated in the indoor field A, and the air pollution is drained through the filter element 22 for filtration and removal multiple times. That is to say, the cloud computing service device 4 intelligently calculates the cleanliness of the suspended particulate matter particle number in the indoor field A in real time, and intelligently selects and issues a control instruction to be transmitted to multiple air purification devices 2, timely mobilizing and controlling the start of the fan 21 of the air purification device 2, and being able to randomly adjust the air volume and start time period of the fan 21 according to the real-time cleanliness of the suspended particulate matter particle number, improving the purification efficiency of the indoor field A and reducing the environmental noise of the indoor field A, generating an internal circulation directional air flow in the indoor field A, quickly draining the air pollution through the filter element 22 for filtration and removal multiple times, so that the air pollution state of the indoor field A is calibrated by the detection time, meeting the clean room grade requirements.

[0104] The above cleanroom grade requirements state that the cleanliness grades of ZAP Clean room 1 to 9 are equivalent to those of ISO Clean room 1 to 9. However, ZAP Clean room 1 to 9 has a technical architecture different from the traditional ISO Clean room 1 to 9 grades and can achieve the same indoor air cleanliness as the traditional ISO Clean room 1 to 9 grades. Generally, the traditional ISO Clean room 1 to 9 grades do not have sensors for round-the-clock real-time detection, so it needs to operate at high speed for 24 hours a day. Such an operation mode will result in a large amount of energy loss and a high-noise environment, and such a system cannot be applied to general indoor home life. The general home environment specifications comply with the ZAP Clean room 6+, 6, 6- grades and the ZAP Clean room 7+, 7, 7- grades of this invention. The cleanliness grades of ZAP Clean room 6+, 6, 6- are the same as ISO 6 grade cleanliness, and the cleanliness grades of ZAP Clean room 7+, 7, 7- are the same as ISO 7 grade cleanliness.

[0105] The indoor air purification system of this invention belongs to the ZAP Clean room 6+, 6, 6- grades and the ZAP Clean room 7+, 7, 7- grades. The indoor air purification system of this invention utilizes multiple air purification devices (gas exchanger 2a, circulation filtration device 2b, negative pressure exhaust fan 2c, smoke exhaust machine 2d, bathroom exhaust fan 2e) with built-in gas detection modules and a cloud computing service device to form an intelligent linkage system. The gas detection modules installed externally and inside the equipment are used to detect the PM2.5 concentration / particle number, carbon dioxide (CO2), carbon monoxide (CO), formaldehyde, total volatile organic compounds (TVOC), ozone (O3), bacteria, and fungi. It can transmit and connect to the cloud computing service device through wired or wireless communication, and the intelligent operation selects and provides control command signals to the gas detection modules of multiple air purification devices to regulate the start-up operation, air volume speed, and noise level of the fans, so as to achieve a ZAP Clean room system with quiet and efficient operation.
