[0006] Embodiments illustrating the features and advantages of the present invention will be described in detail in the following description. The present invention can have various variations in different embodiments, all of which will not depart from the scope of the invention, and it should be understood that the description and drawings are used essentially for illustrative purposes and are not intended to limit the invention.

[0007] As shown in Figure 1, the present invention is a network-connected smart total heat exchanger comprising a main body 1, at least one filtration and purification component 2, at least one air guide device 3, a heat exchange core 4, at least one host drive controller 5, and at least one gas detection module 6. In this embodiment of the present invention, two filtration and purification components 2, two air guide devices 3, one host drive controller 5, and one gas detection module 6 are provided, but the invention is not limited to this, and the number can be changed according to actual demand.

[0008] The main body 1 is provided with an intake passage 11 and an exhaust passage 12, and the filtration and purification component 2 is installed at the inlet of the intake passage 11 and the inlet of the exhaust passage 12. The air guide device 3 is installed behind the filtration and purification component 2 at the inlet of the intake passage 11 and behind the filtration and purification component 2 at the inlet of the exhaust passage 12. The air guide device 3 guides the gas to pass through the filtration and purification component 2 for purification treatment and also guides the gas to achieve air exchange between the indoor and outdoor areas. The heat exchange core 4 is provided inside the main body 1 and communicates with the intake passage 11 and the exhaust passage 12, respectively, but the intake passage 11 and the exhaust passage 12 do not communicate with each other. The intake passage 11 is separated by a heat exchange core 4 so that one end communicates with the indoor area and the other end communicates with the outdoor area, and the exhaust passage 12 is separated by a heat exchange core 4 so that one end communicates with the indoor area and the other end communicates with the outdoor area. Gas is introduced and passes through the heat exchange core 4, and heat exchange takes place. The intake passage 11 guides gas from the outdoor area to the indoor area, and the exhaust passage 12 guides gas from the indoor area to the outdoor area, realizing air exchange between the indoor and outdoor areas. The host drive controller 5 controls the activation of the air guide device 3 and dynamically adjusts the operating frequency and output airflow rate of the air guide device 3. As shown in Figure 2, the gas detection module 6 is electrically connected to the host drive controller 5. The gas detection module 6 detects the temperature, humidity, and air pollution of the air, outputs detection data, and transmits the detection data to the network-connected cloud computing service device 7 via the Internet of Things communication. The network-connected cloud computing service device 7 collects and analyzes the detection data, monitors the detection data in real time, intelligently selects and transmits control commands to the gas detection module, controls the host drive controller 5 to operate the air guide devices 3 in the intake passage 11 and exhaust passage 12, and dynamically adjusts the operating frequency and output airflow rate of the air guide devices 3 to realize air circulation, exchange, and heat exchange between the indoor and outdoor areas.The above-mentioned air pollution refers to any or a combination thereof of suspended particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, lead, total volatile organic compounds, formaldehyde, bacteria, fungi, viruses. In the embodiments of the present invention, the detection data output by the gas detection module 6 may include suspended particulate matter (PM1, PM2.5, PM10), carbon dioxide (CO2) concentration, temperature, humidity, etc.

[0009] As shown in Figure 2, the gas detection module 6 includes a control circuit board 61 and a gas detection unit 62. The gas detection unit 62 detects air pollution, carbon dioxide (CO2) concentration, temperature, and humidity and outputs detection data, while the control circuit board 61 collects, calculates, analyzes, and outputs the detection data to form an input serial communication (IIC) signal. The network-connected cloud computing service device 7 receives and analyzes the detection data in real time and outputs general-purpose asynchronous transceiver (UART) signals and general-purpose input / output (GP I / O) signals to the host drive controller 5.

[0010] The control circuit board 61 includes a power converter 611, at least one connection interface 612, a microcontroller (MCU) 613, and a wireless communication device 614. The power converter 611 divides and modulates a DC voltage to output the required DC voltage, which is then provided to the gas detection unit 62 and the host drive controller 5 for startup operation via at least one connection interface 612. The microcontroller (MCU) 613 is connected to the gas detection unit 62 via the connection interface 612 and forms the serial communication (IIC) signals for input based on the output detection data in order to calculate and analyze the detection data. It is also connected via another connection interface 612 and outputs general-purpose asynchronous transceiver (UART) signals and general-purpose input / output (GP I / O) signals for control. The wireless communication device 614 receives the detection data and transmits it to the network-connected cloud computing service device 7 via wireless communication. The network-connected cloud computing service device 7 collects and analyzes detection data, monitors it in real time, intelligently selects control commands, transmits them to the wireless communication device 614, and further transmits them to the microcontroller (MCU) 613. The microcontroller (MCU) 613 outputs general-purpose asynchronous transceiver (UART) signals and general-purpose input / output (GP I / O) signals to control the host drive controller 5. This controls the host drive controller 5 to operate the air duct 3, dynamically adjusting the operating frequency and output airflow of the air duct 3, and activating the temperature control module of the heat exchange core 4 to control its cooling or heating operation mode. The output airflow of the air duct 3 is 500 m³. 3 The noise level is 35-50 dB (decibels) when the air guide device 3 is operating, and the noise level is 35-50 dB (decibels).

[0011] In addition, the gas detection module 6 further includes a wired communication connection port 615. The wired communication connection port 615 is electrically connected to the control circuit board 61 via the connection interface 612, and transmits the received detection data to the network connection type cloud computing service device 7 through wired line communication with the external. The network connection type cloud computing service device 7 collects and analyzes the detection data, monitors it in real time, intelligently selects control commands, and transmits them to the microcontroller (MCU) 613 via the wired communication connection port 615. The microcontroller (MCU) 613 outputs general-purpose asynchronous transceiver (UART) signals and general-purpose input / output (GPIO) signals to control the host drive controller 5, thereby controlling the host drive controller 5 to operate the air guiding device 3, dynamically adjusting the operation frequency and output air volume of the air guiding device 3, starting the temperature adjustment module of the heat exchange core 4, and controlling the operation of its cooling or heating operation mode. The wired communication connection port 615 is an RS485 connection port and communicates with the network connection type cloud computing service device 7 via a wired line connection.

[0012] As shown in Figure 11, the network-connected cloud computing service device 7 includes a wireless network cloud computing service module 71, a cloud control service unit 72, a device management unit 73, an application unit 74, and an AI intelligent computing platform 75. The wireless network cloud computing service module 71 receives air quality detection data from the outdoor and indoor areas, receives communication information from the gas detection module 6 of the network-connected smart total heat exchanger, and issues control commands. The wireless network cloud computing service module 71 transmits the received indoor area air quality detection data information to the cloud control service unit 72 to form and store an air pollution big data database. The cloud control service unit 72 performs intelligent calculations and compares the air pollution database to issue control commands, which are then transmitted to the wireless network cloud computing service module 71 and then transmitted to the gas detection module 6 of the network-connected smart total heat exchanger via the wireless network cloud computing service module 71 to control its startup operation. The device management unit 73 receives communication information from the gas detection module 6 via the wireless network cloud computing service module 71 for user login management and device binding management, and can provide management information to the application unit 74 for system control management, such as maintenance management of the network-connected smart total heat exchanger, automatic anomaly detection, analysis, processing and improvement, customer request feedback, and hardware and software technology improvement and correction mechanisms. The application unit 74 displays and notifies users of air quality detection data information acquired by the cloud control service unit 72, allowing users to understand the real-time status of the network-connected smart total heat exchanger via a mobile phone or communication device and control the operation of the network-connected smart total heat exchanger via the application unit 74 on the mobile phone or communication device.The AI ​​intelligent computing platform 75 receives and analyzes air quality detection data from the gas detection module 6 of the network-connected smart total heat exchanger via Internet of Things technology. Based on the analysis results, it generates control commands to enable automatic control and optimization of the network-connected smart total heat exchanger, thereby automatically adjusting the operating mode of the network-connected smart total heat exchanger.

[0013] The above-mentioned Internet of Things communication refers to a collective network connecting various devices and technology that supports mutual communication between devices and between the cloud and devices. The Internet of Things communication may also be wired communication for connecting and communicating with the network-connected cloud computing service device 7 via a wired line. The Internet of Things communication may also be wireless communication for connecting and communicating with the network-connected cloud computing service device 7 via a wireless connection. The wireless communication may be any of the following: a Wi-Fi module, a Bluetooth® module, a radio frequency identification module, or a near-field communication module.

[0014] In the specific implementation of the network-connected smart total heat exchanger of the present invention, the AI intelligent computing platform 75 of the network-connected cloud computing service device 7 monitors the detection data of carbon dioxide (CO2) in real time. When the detection data is too high, it immediately selects an intelligent control command and sends it to the gas detection module 6 to control the host drive controller 5 to operate the air guiding device 3 in the intake passage 11 and the exhaust passage 12. As a result, the gas in the outdoor area is introduced, filtered by the filtration and purification component 2, heat exchange is performed through the heat exchange core 4, and then it is introduced into the indoor area from the intake passage 11 at the other end. On the other hand, the circulating gas in the indoor area is introduced from the exhaust passage 12, filtered by the filtration and purification component 2, and then heat exchange is performed through the heat exchange core 4. Furthermore, it is introduced into the exhaust passage 12 at the other end and discharged to the outdoor area, thereby realizing the air exchange between the outdoor area and the indoor area (the air exchange in the direction indicated by the arrow in FIG. 1). In this way, the AI intelligent computing platform 75 of the network-connected cloud computing service device 7 receives, analyzes, and calculates the detection data, realizes AI intelligent control, environmental data analysis, and automated operation, monitors the environmental air quality state of the indoor area in real time, continuously adjusts the temperature and humidity of the indoor area, provides fresh and comfortable air, and can realize efficient and energy-saving indoor temperature control.

[0015] As can be seen from the above description, the present invention provides a network-connected smart total heat exchanger. In this network-connected smart total heat exchanger, the gas detection module 6 can continuously monitor the environment (including temperature, humidity, carbon dioxide (CO2) concentration, and air pollution), and the AI ​​intelligent computing platform 75 of the network-connected cloud computing service device 7 receives, analyzes, and calculates the detection data to realize AI intelligent control, environmental data analysis, and automated operation, and can monitor the environmental air quality state of the indoor area in real time. If the carbon dioxide (CO2) concentration in the indoor area is too high, fresh outdoor air is introduced and filtered to achieve air exchange, and the temperature and humidity of the indoor area are adjusted to provide fresh and comfortable air, achieving efficient and energy-saving indoor temperature control. As a result, the indoor area environment can respond quickly to real-time environmental changes, optimize the energy efficiency of the system, and maintain optimal air quality.

[0016] Refer to Figures 4A to 9C. After understanding the overall structure and architecture of the network-connected smart total heat exchanger of the present invention, the detailed structure of the gas detection unit 62 of the gas detection module 6 will be described below.

[0017] Refer to Figures 4A, 4B, 5, 6A to 6C, and 7. The gas detection unit 62 includes a base 621, a piezoelectric actuator 622, a drive circuit board 623, a laser component 624, a particulate sensor 625, an outer cover 626, and a gas sensor 627.

[0018] The base 621 has a laser mounting area 6211, an intake groove 6212, an air guide component mounting area 6213, and an exhaust groove 6214. An intake vent 6215 is provided in the intake groove 6212, and light-transmitting windows 6216 penetrate through both side walls, communicating with the laser mounting area 6211. The air guide component mounting area 6213 communicates with the intake groove 6212, and a ventilation hole 6217 penetrates through its bottom surface. The exhaust groove 6214 communicates with the ventilation hole 6217 and is provided with an exhaust vent 6218. The outer cover 626 covers the base 621 and has a side plate 6261 with an intake frame opening 6262 and an exhaust frame opening 6263. The intake frame opening 6262 corresponds to the intake vent 6215 of the base 621, and the exhaust frame opening 6263 corresponds to the exhaust vent 6218 of the base 621.

[0019] The laser component 624, particulate sensor 625, and gas sensor 627 are all mounted on the drive circuit board 623 and are electrically connected as a whole. When the drive circuit board 623 is covered, they are located within the base 621. The drive circuit board 623 is intentionally omitted in this explanation to clearly illustrate the positions of the laser component 624, particulate sensor 625, and base 621. The laser component 624 is housed within the laser mounting area 6211 of the base 621, and the particulate sensor 625 is housed within the intake groove 6212 of the base 621 and aligned with the laser component 624. The laser component 624 also irradiates the intake groove 6212 with laser light by corresponding to the light transmission window 6216 through which the laser light emitted by the laser component 624 passes. The beam path emitted by the laser component 624 passes through the light transmission window 6216 and is perpendicular to the intake groove 6212. The beam emitted by the laser component 624 passes through the light-transmitting window 6216 and enters the intake groove 6212. When the gas in the intake groove 6212 is irradiated and the beam comes into contact with suspended particles in the gas, it scatters and generates a projection spot. The particle sensor 625 is positioned perpendicular to this spot and receives the scattered projection spot and performs calculations to acquire gas detection data. The light source emitted by the laser component 624 is a parallel light source and passes through the light-transmitting window 6216.

[0020] The gas sensor 627 described above is positioned and housed within the exhaust channel 6214 and detects air pollution introduced into the exhaust channel 6214. In a preferred embodiment of the present invention, the particulate sensor 625 detects suspended particulate matter and outputs detection data. The gas sensor 627 is a volatile organic compound sensor that detects carbon dioxide or total volatile organic compound gas and outputs detection data, or a formaldehyde sensor that detects formaldehyde gas and outputs detection data, or a bacterial sensor that detects bacteria or fungi and outputs detection data, or a virus sensor that detects virus gas and outputs detection data, or a temperature and humidity sensor that detects the temperature and humidity of the gas and outputs detection data.

[0021] Refer to Figure 7. The piezoelectric actuator 622 is housed in the air conductor component mounting area 6213 of the base 621, and the air conductor component mounting area 6213 is in communication with the intake groove 6212. When the drive circuit board 623 is covered inside the base 621 and the outer cover 626 covers the outside of the base 621, the intake frame opening 6262 defines an intake path corresponding to the intake vent 6215 of the base 621, and the exhaust frame opening 6263 defines an exhaust path corresponding to the exhaust vent 6218 of the base 621. When the piezoelectric actuator 622 is activated, it draws gas from the intake groove 6212 into the piezoelectric actuator 622, and the gas passes through the vent hole 6217 of the air conductor component mounting area 6213 and enters the exhaust groove 6214. Finally, after the gas enters the exhaust channel 6214, the piezoelectric actuator 622 continues to transport the gas to the exhaust channel 6214 via the intake path, so that the gas in the exhaust channel 6214 is pushed out into the exhaust path and discharged to the outside through the exhaust port 6218 and the exhaust frame port 6263, achieving high-speed and high-volume gas transport.

[0022] Having understood the above explanation of the structure of the gas detection unit 62, the detailed structure of the piezoelectric actuator 622 will be explained below.

[0023] Refer to Figures 8A and 8B. The piezoelectric actuator 622 includes a gas orifice plate 6221, a chamber housing 6222, an actuator 6223, an insulating housing 6224, and a conductive housing 6225. The gas orifice plate 6221 is made of a flexible material and has a suspension plate 6221a and a hollow hole 6221b, the suspension plate 6221a being a sheet-like structure that bends and vibrates, its shape and dimensions corresponding to the inner edge of the gas guide component mounting area 6213, and the hollow hole 6221b passing through the center of the suspension plate 6221a to allow gas to flow. In a preferred embodiment of the present invention, the shape of the suspension plate 6221a may be square, circular, elliptical, triangular, or polygonal.

[0024] The chamber housing 6222 is superimposed on the gas orifice plate 6221, and its appearance corresponds to that of the gas orifice plate 6221. The actuator 6223 is superimposed on the chamber housing 6222, defining a resonant chamber 6226 between the chamber housing 6222 and the suspension plate 6221a. The insulating housing 6224 is superimposed on the actuator 6223, and its appearance approximates that of the chamber housing 6222. The conductive housing 6225 is superimposed on the insulating housing 6224, and its appearance approximates that of the insulating housing 6224. The conductive housing 6225 has conductive pins 6225a and conductive electrodes 6225b extending outward from the outer edge of the conductive pins 6225a, with the conductive electrodes 6225b extending inward from the inner edge of the conductive housing 6225.

[0025] The actuator 6223 further includes a piezoelectric carrier plate 6223a, a resonance adjustment plate 6223b, and a piezoelectric plate 6223c. The piezoelectric carrier plate 6223a is superimposed on the chamber housing 6222. The resonance adjustment plate 6223b is superimposed on the piezoelectric carrier plate 6223a. The piezoelectric plate 6223c is superimposed on the resonance adjustment plate 6223b. The resonance adjustment plate 6223b and the piezoelectric plate 6223c are housed in an insulating housing 6224. The piezoelectric plate 6223c is electrically connected to the conductive housing 6225 by conductive electrodes 6225b. In a preferred embodiment of the present invention, both the piezoelectric carrier plate 6223a and the resonance adjustment plate 6223b are made of conductive material. The piezoelectric carrier plate 6223a has piezoelectric pins 6223d, and the piezoelectric pins 6223d and conductive pins 6225a are connected to a drive circuit (not shown) on the drive circuit board 623 to receive a drive signal (which may be a drive frequency and drive voltage). The drive signal can form a loop through the piezoelectric pins 6223d, piezoelectric carrier plate 6223a, resonance adjustment plate 6223b, piezoelectric plate 6223c, conductive electrode 6225b, conductive housing 6225, and conductive pins 6225a, and the insulating housing 6224 isolates the conductive housing 6225 from the actuator 6223, preventing a short circuit and allowing the drive signal to be transmitted to the piezoelectric plate 6223c. After receiving the drive signal, the piezoelectric plate 6223c deforms due to the piezoelectric effect and further drives the piezoelectric carrier plate 6223a and resonance adjustment plate 6223b to generate reciprocating bending vibrations.

[0026] To explain further, the resonance adjustment plate 6223b is positioned between the piezoelectric plate 6223c and the piezoelectric carrier plate 6223a as a buffer between them, and can adjust the vibration frequency of the piezoelectric carrier plate 6223a. Basically, the thickness of the resonance adjustment plate 6223b is greater than the thickness of the piezoelectric carrier plate 6223a, and the vibration frequency of the actuator 6223 is adjusted by changing the thickness of the resonance adjustment plate 6223b. The gas orifice plate 6221, chamber housing 6222, actuator 6223, insulating housing 6224, and conductive housing 6225 are sequentially stacked and positioned within the gas conductor component mounting area 6213, thereby positioning the piezoelectric actuator 622 within the gas conductor component mounting area 6213, and the piezoelectric actuator 622 defines a gap 6221c for gas to flow between the suspension plate 6221a and the inner edge of the gas conductor component mounting area 6213.

[0027] An airflow chamber 6227 is formed between the gas orifice plate 6221 and the bottom surface of the gas guide component mounting area 6213. The airflow chamber 6227 communicates with a resonant chamber 6226 between the actuator 6223, the chamber housing 6222, and the suspension plate 6221a via the hollow hole 6221b of the gas orifice plate 6221. By making the vibration frequency of the gas in the resonant chamber 6226 the same as the vibration frequency of the suspension plate 6221a, the resonant chamber 6226 and the suspension plate 6221a produce a Helmholtz resonance effect, which increases the gas transport efficiency. When the piezoelectric plate 6223c moves away from the bottom surface of the air conductor mounting area 6213, the piezoelectric plate 6223c moves the suspension plate 6221a of the gas orifice plate 6221 away from the bottom surface of the air conductor mounting area 6213, causing the volume of the airflow chamber 6227 to rapidly expand, the internal pressure to decrease and negative pressure to be generated. This draws in gas from outside the piezoelectric actuator 622, which flows in through the gap 6221c, passes through the hollow hole 6221b and enters the resonant chamber 6226, increasing the air pressure inside the resonant chamber 6226 and generating a pressure gradient. When the piezoelectric plate 6223c moves the suspension plate 6221a of the gas orifice plate 6221 to the bottom surface of the gas conductor component mounting area 6213, the gas in the resonant chamber 6226 rapidly flows out through the hollow hole 6221b, squeezing out the gas in the airflow chamber 6227, and the combined gas is rapidly and abundantly ejected through the vent hole 6217 of the gas conductor component mounting area 6213 in an ideal gas state close to Bernoulli's theorem.

[0028] By repeating the operations shown in Figures 9B and 9C, the piezoelectric plate 6223c vibrates back and forth. According to the principle of inertia, when the internal pressure of the resonant chamber 6226 after exhaust falls below the equilibrium pressure, the gas is guided back into the resonant chamber 6226. In this way, the vibration frequency of the gas in the resonant chamber 6226 is controlled to be the same as the vibration frequency of the piezoelectric plate 6223c, thereby generating a Helmholtz resonance effect and achieving high-speed, high-volume gas transport.

[0029] Refer to Figures 10A to 10C. All the gas enters through the intake frame port 6262 of the outer cover 626, passes through the intake vent 6215, enters the intake groove 6212 of the base 621, and flows to the position of the particulate sensor 625. In addition, by continuously driving the piezoelectric actuator 622 to draw in the gas in the intake path, the external gas is introduced rapidly and flows stably, passing above the particulate sensor 625. At this time, the beam emitted by the laser component 624 enters the intake groove 6212 through the light transmission window 6216, and the intake groove 6212 passes above the particulate sensor 625. When the beam of the particulate sensor 625 irradiates suspended particulate matter in the gas, scattering phenomena and projection spots occur. The particulate sensor 625 receives the projection spots caused by scattering and performs calculations to obtain relevant information such as the particle size and quantity of suspended particulate matter contained in the gas. The gas above the particulate sensor 625 is also introduced into the vent holes 6217 of the gas guide component mounting area 6213 by continuous driving by the piezoelectric actuator 622 and enters the exhaust channel 6214. Finally, after the gas enters the exhaust channel 6214, the piezoelectric actuator 622 continues to transport the gas to the exhaust channel 6214, so the gas in the exhaust channel 6214 is pushed out and discharged to the outside through the exhaust outlet 6218 and exhaust frame opening 6263, realizing high-speed and high-volume gas transport.

[0030] Refer to Figure 3. The filtration and purification component 2 of the present invention can be a combination of various embodiments. In a specific embodiment, the filtration and purification component 2 may be a filter 2a. The filter 2a may be a filter of MREV 8 or higher (minimum efficiency reported value) level, or a high-efficiency particulate air (HEPA) level, and achieves the effect of filtering and purifying introduced air pollution by adsorbing chemical smog, bacteria, dust particles and pollen contained in the air pollution. Alternatively, the high-efficiency air (HEPA) filter of the present invention is a high-efficiency air (HEPA) 10 or higher, with a dust holding capacity exceeding 12,000 mg. Or, the filter 2a may be a more efficient ULPA 14 filter level, further improving filtration efficiency and meeting higher cleanliness requirements. In some specific embodiments, the filtration and purification component 2 can be further combined with physical or chemical materials to provide a sterilizing effect on air pollution, and the airflow path direction of the air guide device 3 is indicated by the arrow. By applying a decomposition layer to the filtration and purification component 2, air pollution is chemically sterilized and removed. The decomposition layer may be activated carbon 2b, which removes organic and inorganic substances in air pollution, as well as colored and odorous substances. In this invention, the formaldehyde adsorption capacity of activated carbon 2b exceeds 1500 mg. In some embodiments, the filtration and purification component 2 can also be combined with a light irradiation element to chemically sterilize and remove air pollution. The light irradiation element is a photocatalytic unit including a photocatalyst 2c and an ultraviolet lamp 2d, which further improves the efficiency of removing pollutants and allergens from the air. When the photocatalyst 2c is irradiated by the ultraviolet lamp 2d, it converts light energy into electrical energy, decomposing harmful substances in air pollution and achieving filtration and sterilization effects through disinfection and sterilization. In this invention, the output of the ultraviolet lamp 2d is 120 mW or more.The light irradiation element may be a photoplasma unit containing a photo-nanotube 2e. By irradiating the introduced air pollutants with the photo-nanotube 2e, oxygen molecules and water molecules in the air pollutants are decomposed into a highly oxidizing photoplasma, forming an ionized gas stream with destroyed organic molecules. This decomposes gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOCs) contained in the air pollutants into water and carbon dioxide, further improving the efficiency of removing airborne pollutants and allergens and achieving a filtration and sterilization effect. In some embodiments, the filtration and purification component 2 can also be combined with the decomposition unit to chemically sterilize and remove air pollutants. The decomposition unit may be a negative ion unit 2f. By attaching positively charged fine particles contained in the introduced air pollutants to the negative charge, the efficiency of removing airborne pollutants and allergens is further improved, achieving a filtration and sterilization effect of the introduced air pollutants. The decomposition unit may be a plasma ion unit 2g. Plasma ions ionize oxygen molecules and water molecules contained in the air pollutants to cations (H. + ) and anions (O 2- The substance generates ions, and water molecules are attached to the ions. After attaching to the surface of viruses and bacteria, it undergoes a chemical reaction that converts them into highly oxidative reactive oxygen species (hydroxyl groups, OH groups). These reactive oxygen species deplete hydrogen from the surface proteins of viruses and bacteria, causing oxidative decomposition. This decomposes and removes airborne pollutants, allergens, and microorganisms, improving air purity and achieving the effect of filtering and sterilizing introduced air pollution. The decomposition unit may also be an electrostatic filtration unit 2h, which uses electrostatic force to capture and remove airborne particles (dust, pollen, bacteria, and other pollutants).

[0031] As described above, the network-connected smart total heat exchanger of the present invention has the following effects in specific implementations: Intelligent heat recovery adjustment: By operating the air guides in the intake and exhaust passages, the air exchange operation is adjusted based on temperature and humidity data. The air guide in the intake passage draws in gas from the outdoor area, passes it through the heat exchange core for heat exchange, and then introduces it into the indoor area. The air guide in the exhaust passage draws in gas from the indoor area, passes it through the heat exchange core for heat exchange, and then discharges it to the outdoor area, thereby improving ventilation efficiency, recovering heat, and maintaining a stable indoor temperature. Automatic ventilation and airflow control: If the indoor CO2 or PM2.5 concentration exceeds the standard, the ventilation volume is automatically increased and the airflow speed is adjusted to keep the indoor air clean. Intelligent filtration mode: If the outdoor air quality is poor, the system automatically adjusts to low ventilation mode and uses filtration and purification components to purify the air entering the room. Remote control and monitoring: Users can check indoor and outdoor environmental conditions and operate the equipment remotely via a network-connected cloud computing service platform or mobile phone app. Energy-saving mode: When indoor and outdoor temperature and humidity are similar or air quality meets the standard, the system automatically reduces the operating frequency and enters energy-saving mode to reduce power consumption.

[0032] As described above, the present invention provides a network-connected smart total heat exchanger. This network-connected smart total heat exchanger uses a built-in gas detection module to detect indoor and outdoor air quality in real time. The gas detection module is equipped with cloud connectivity, allowing the user to remotely monitor environmental conditions and control the equipment. Through Internet of Things communication, the ventilation rate and heat recovery efficiency are dynamically adjusted based on data such as temperature, humidity, and air quality to maintain optimal indoor air quality.
