[0002] With the development of air purification technology, the use of air treatment equipment such as purification devices, fresh air devices, and air conditioning devices has become more and more widespread. However, in winter or other dry environments, the indoor air is dry. Being in a dry environment for a long time will cause people to feel dry mouth, dry eyes, cracked skin and other discomfort symptoms. In addition, in warm and dry environmental conditions, some pathogens such as bacteria and viruses can easily escape and spread, resulting in a significant increase in infectiousness, which is easy to cause diseases for the elderly and children with poor resistance.

[0074] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0075] Being in a dry environment for a long time will make people feel uncomfortable symptoms such as dry mouth, dry eyes, and chapped skin. In addition, in a warm and dry environment, some pathogens such as bacteria and viruses can easily escape and spread, causing the infectiousness to increase significantly. It is easy for the elderly and children with poor resistance to get sick.

[0076] In order to improve the indoor air quality, the present invention proposes an air treatment system and a control method for the air treatment system. The air treatment system integrates multiple air treatment functions such as ventilation (supplying fresh air and exhausting air), humidification, and air conditioning, so as to jointly adjust the ventilation and humidification modes according to the indoor air environment, improve the indoor dry environment, enhance the comfort of the indoor environment, and reduce the infectivity of pathogens.

[0077] Figure 1 A schematic diagram of an air treatment system according to an embodiment of the present invention.

[0078] like Figure 1 As shown, an air treatment system 100 according to an embodiment of the present invention includes: a ventilation unit 1, a humidification unit 2, a detection unit 3 and a control unit 4.

[0079] The air handling system 100 further includes an air conditioning unit 5 , an air distribution module 6 , a plurality of air supply ports 7 , and a plurality of air valves 150 .

[0080] exist Figure 1 In the figure, the solid lines between the units, modules or devices represent the refrigerant circuit 51, the pipes with arrows connecting the units, modules or devices are air pipes 140, 141, and the dotted lines between the units, modules or devices represent communication connections, which can be wired connections or wireless connections.

[0081] The ventilation unit 1 is used to introduce air. The ventilation unit 1 is provided with an air supply path for introducing fresh air and an exhaust path for exhausting indoor dirty air. An internal circulation path for circulating indoor air can also be provided. The internal circulation mode is adopted to simply circulate indoor air. A paper heat exchanger is usually provided in the ventilation unit 1. The paper heat exchanger is connected to the air supply path and the exhaust path respectively. During ventilation, the introduced fresh air and the exhausted air are heat exchanged via the paper heat exchanger. The paper heat exchanger may not be provided in the ventilation unit 1. In order to ensure the cleanliness of the air finally delivered to the room, a filter element may also be provided on the air supply path and the internal circulation path, for example, to filter dust in the air, specific chemical components in the air, specific pathogens in the air, etc. Dust includes, for example, pollen, sand, inhalable particulate matter (PM2.5, PM10), etc. Specific chemical components include carbon dioxide (CO2), formaldehyde, odorous substances, etc., to improve air quality.

[0082] The humidifying unit 2 is a unit for adjusting the humidity of the air flowing through the unit. The ventilation unit 1 is connected to the humidifying unit 2. The air is processed by the ventilation unit 1 and then transported to the humidifying unit 2, so that the air output by the humidifying unit 2 has a certain humidity, thereby improving the dry environment in the room and enhancing the comfort of the indoor environment.

[0083] The air distribution module 6 is connected to the humidification unit 2, and the air humidified by the humidification unit 2 is sent to the air distribution module 6. The air distribution module 6 has multiple air outlets 61. Multiple air valves 150 are respectively arranged at the multiple air outlets 61 of the air distribution module 6, and are respectively connected to the air pipeline 140. The air pipeline 140 is connected to multiple air supply ports 7, and the multiple air supply ports 7 are located in multiple areas of the room to supply air to multiple areas respectively. All the air outlets 61 can be used, and some of the air outlets 61 can also be used as needed.

[0084] The number of the air outlets 61 can be designed according to actual needs. The ratio of the air output by the multiple air outlets 61 can be set according to actual needs, for example, the air flow rates of the air outlets 61 are the same or different.

[0085] The air pipeline 140 is an air inlet pipe, and each air pipeline 140 corresponds to a different indoor area.

[0086] For example, Figure 1 As shown, an air duct 141 serving as a return air duct may also be provided to centrally return air to each indoor space or each area and discharge the air to the outdoors.

[0087] Figure 2 FIG. 1 is a system schematic diagram of an air treatment system 101 according to another embodiment of the present invention.

[0088] like Figure 2 As shown, the structure of the air handling system 101 is Figure 1 The structure of the air handling system 100 in FIG. 1 is substantially the same as that of the air handling system 101 , except that the air handling system 101 does not have an air distribution module 6 , and a plurality of air valves 150 are disposed in the air pipeline 140 . Figure 2 As shown, the humidifying unit 2 has a plurality of air outlets 121 , and a plurality of air valves 150 are respectively disposed at the plurality of air outlets 121 to independently control the humidified air flow output from each air outlet 121 .

[0089] like Figure 2 As shown, the humidifying unit 2 has a plurality of air outlets 121, and the air outlets 121 are respectively connected to the air pipelines 140. For example, all the air outlets 121 can be used, or part of the air outlets 121 can be used as needed. The number of the air outlets 121 can be designed according to actual needs.

[0090] Figure 3 FIG. 1 is a system schematic diagram of an air treatment system 102 according to another embodiment of the present invention.

[0091] like Figure 3 As shown, the structure of the air handling system 102 is Figure 2 The structure of the air handling system 101 in the embodiment is substantially the same as that of the air handling system 101 , but the difference from the air handling system 101 is that the multiple air valves 150 in the air handling system 102 are respectively arranged at the air outlets of the multiple air pipelines 140 .

[0092] Figure 2 and Figure 3 In, with Figure 1 The same parts can be referred to in Figure 1 The relevant instructions will not be repeated.

[0093] exist Figure 2 and Figure 3 In the embodiment of, the indoor area, the air supply port 7, the air duct 140 and the air valve 150 are corresponding. By controlling the air valve 150 corresponding to the indoor space, the flow rate of the humidified air entering the indoor area can be independently controlled, so that the air humidity of the indoor area can be independently adjusted. Therefore, by respectively arranging air valves inside or at the air outlets of multiple air ducts, the valves can be used to control the humidified air input to different indoor areas respectively, so that the air humidity of different indoor areas can be independently adjusted, and refined humidity adjustment for different indoor areas can be achieved to meet the needs of different users, thereby improving the user's comfort and usage experience. Figure 1 Compared with the embodiment of the present invention, since the air distribution module 6 is not provided, the system structure can be further simplified.

[0094] The detection unit 3 is a unit for detecting the air environment, including one or more types of sensors selected from the group consisting of a temperature and humidity sensor, a CO2 sensor, a PM2.5 sensor, a VOC sensor, a TVOC sensor, a formaldehyde sensor, and an odor sensor, and is capable of detecting indoor air humidity values, outdoor air humidity values, indoor air quality, outdoor air quality, etc.

[0095] The detection unit 3 detects the indoor air humidity in real time and generates the detected air humidity detection value H N The detection unit 3 for detecting indoor air parameters can be integrated in a housing, independently set at any position of the detected space, or set in the housing of the ventilation unit.

[0096] For example, the detection unit 3 includes at least one of a first sensor set in the indoor space, a second sensor set in the remote control, and a third sensor set at the indoor return air outlet. The first sensor is a humidity sensor, the second sensor is a temperature sensor, and the third sensor includes a humidity sensor and a temperature sensor.

[0097] The first sensor includes a plurality of humidity sensors in different indoor spaces or in different areas of the same indoor space. In this way, the accuracy of humidity data can be improved, the accuracy of humidity adjustment can be further improved, and the comfort of users can be improved.

[0098] The detection unit 3 further includes a fourth sensor disposed at the output side of the humidification unit 2 , and the fourth sensor is a humidity sensor.

[0099] The indoor humidity is determined using a detection value of at least one of the first sensor, the second sensor, the third sensor, and the fourth sensor.

[0100] The control unit 4 is the control center of the air treatment system 100, 101, 102, which can obtain the detection results of the detection unit 3 and control the operation of the ventilation unit 1 and the humidification unit 2. The control unit 4 includes a remote control, a wired controller, and a control terminal (a mobile phone, a computer, etc.); it can be integrated or separated (different devices are controlled by different control elements, for example, the humidification device and the ventilation unit share a wired controller, and the air conditioning unit 5 has an independent air conditioning controller).

[0101] The control unit 4 receives the humidity detection value H transmitted by the detection unit 3. N Then compare it with the humidity preset value H Y By comparison, it can be determined whether the current indoor humidity is maintained at a humidity comfort level suitable for the human body.

[0102] Humidity preset value H Y It can be set according to different usage requirements. Humidity preset value H Y It is a humidity value suitable for the indoor environment, which can be pre-set in the control logic of the control unit 4, or manually set by the user. As for the user's perceived comfort, the body feels comfortable when the relative humidity of the normal environment is 30%-60%; when the relative humidity of the environment is less than 30%, the human body feels uncomfortable, especially the dryness of the respiratory mucosa, which can easily cause coughing, etc.; when the relative humidity of the environment is greater than 60%, the human body feels uncomfortable, such as chest tightness, etc. For the indoor environment, if the indoor humidity is high for a period of time (more than 70%), it is easy to breed mold, bacteria, etc., which will damage the home environment and affect the health of users. The dew point temperature can be obtained by combining the indoor temperature, the air supply temperature of the air handling system, etc. When the dew point temperature is met, continuous humidification will form condensation; when the indoor humidity is greater than 80%, indoor condensation and air supply pipelines are prone to condensation.

[0103] The control unit 4 detects the humidity according to the value H N With humidity preset value H Y Based on the comparison result, the operation mode of the humidification unit 2 is adjusted, and at least one of the fresh air introduction amount of the ventilation unit 1 is adjusted.

[0104] The control unit 4 detects the humidity according to the value H N With humidity preset value H Y The humidification amount of the humidification unit 2 can also be adjusted based on the comparison result, so that the indoor humidity value is maintained at the humidity preset value H Y , improving human comfort.

[0105] When the humidity detection value H N Less than the humidity preset value H Y When the humidity detection value H N Greater than the humidity preset value H Y, the humidification amount of the humidification unit 2 is reduced or the humidification unit 2 is stopped.

[0106] Figure 4 It is a schematic diagram of a ventilation unit 1 according to a specific embodiment of the present invention.

[0107] like Figure 4 As shown, the ventilation unit 1 is provided with an air inlet 11, an air supply port 12, an air return port 13 and an air exhaust port 14. The air inlet 11 introduces air from the outside to form fresh air. The air supply port 12 is connected to the humidification unit 2. The fresh air is sent to the humidification unit 2 through the air supply port 12, forming the fresh air introduction mode P1 of the ventilation unit 1, and the fresh air is humidified before being sent into the room; the return air port 13 introduces air from the room and exhausts it to the outside through the air exhaust port 14, forming the exhaust mode P2. In addition, after the return air port 13 introduces indoor air from the room, the indoor air processed by the ventilation unit 1 can also flow back to the room through the air supply port 12, forming the internal circulation mode P3.

[0108] The humidification capacity of the humidification unit 2 is related to the operation mode of the humidification unit 2 and the amount of fresh air introduced by the ventilation unit 1 to the humidification unit 2. When the amount of fresh air introduced is low, the amount of air flowing through the humidification unit 2 is small, the amount of water molecules brought in by the air after passing through the humidification unit 2 is also small, and the humidification capacity is small; when the amount of fresh air introduced is high, the amount of air flowing through the humidification unit 2 is large, the amount of water molecules brought in by the air after passing through the humidification unit 2 is also large, and the humidification capacity is large. Therefore, the control unit 4 determines the humidity detection value H N With humidity preset value H Y After the comparison result is obtained, the operation mode of the humidification unit 2 is adjusted, or the amount of fresh air introduced by the ventilation unit 1 is adjusted, so that the humidification amount of the humidification unit 2 can be adjusted, thereby adjusting the indoor humidity value.

[0109] The control unit 4 selects different humidification modes of the humidification unit 2 according to the indoor humidity value, or adjusts the amount of fresh air introduced by the ventilation unit 1, adjusts the humidification performance of the system, and can humidify accurately to ensure indoor humidity comfort.

[0110] Figure 5 It is a schematic diagram of a humidifying unit 2 according to a specific embodiment of the present invention.

[0111] like Figure 5As shown, an air flow path F1 is formed between the air inlet 24 and the air outlet 121 of the humidifying unit 2. A heating component 23 and a humidifying component 21 are sequentially arranged from the air inlet 24 to the air outlet 121. The humidifying component 21 is provided with a moisture permeable membrane (not shown). A certain amount of water is stored in the humidifying component 21. When humidifying, the water molecules in the humidifying component 21 pass through the moisture permeable membrane into the air side to humidify the air. The moisture permeable membrane material is composed of quaternary ammonium salt compounds with antibacterial effects, so the material itself has antibacterial properties, which can ensure that the moisture permeable membrane will not breed bacteria, ensuring the provision of clean humidified air. Due to the small pores of the moisture permeable membrane, scale on the water side will not enter the humidification air path.

[0112] The heating assembly 23 is a heat exchanger, and is connected to the air conditioning unit 5 via a refrigerant pipe to form a refrigerant circuit 51. The heating assembly 23 may also be an electric heater.

[0113] The humidifying unit 2 supplies water to the humidifying assembly 21 through a water storage component. The water storage component can be a water tank 22 disposed in the humidifying unit 2, or can be a water supply pipe connected to the outside. The amount of water supplied by the water storage component to the humidifying assembly 21 is adjustable. When the amount of water supplied by the water storage component to the humidifying assembly 21 is large, the moisture permeable membrane of the humidifying assembly 21 absorbs more water, so that the humidifying assembly 21 has a higher water level. When the amount of water supplied to the humidifying assembly 21 is small, the moisture permeable membrane of the humidifying assembly 21 absorbs less water, so that the humidifying assembly 21 has a lower water level.

[0114] When the water storage component is a water tank 22, the water tank 22 and the humidification component 21 are connected by a water pipe, and a water valve can be set in the pipeline to control the water supply from the water tank to the humidification component; the water valve can be a three-way valve, and the three-way valve can realize three states: the humidification component and the water tank are connected, the water tank is drained, and the humidification component is drained. The water tank 22 is set in the shell, and the water tank 22 is connected to the municipal water by a water pipe. Before the municipal water enters the water tank 22, a water inlet solenoid valve can be set to control the water inlet amount. Before the municipal water enters the water tank, it is connected to a water purification / soft water device to improve the cleanliness of the water and prevent the humidification component, water pipe, water tank and other equipment from scaling.

[0115] The humidification component 21 is connected to the water tank 22, and the tops are roughly flush. When the humidification component 21 is full of water, the water flow of the humidification component 21 is 100%. When the water level of the humidification component 21 is 100-88%, it is the high water level of the first height interval of the water level. When the water level of the humidification component 21 is 88%-72%, it is the middle water level of the second height interval of the water level. When the water level of the humidification component 21 is 72%→60%, it is the low water level of the third height interval. During the humidification process, if the water level is lower than the third height interval, a water replenishment alarm will be issued. When air (fresh air) flows through the moisture permeable membrane of the humidification component 21, water molecules are taken out, thereby increasing the humidity of the air flowing through. At the same air flow rate, when the water supply to the humidifying component 21 is large, since the air and the water molecules in the moisture permeable membrane have a larger contact area, the humidification amount of the humidifying component 21 at a higher water supply is greater than the humidification amount of the humidifying component 21 at a lower water supply. When the water supply of the humidifying component 21 is the same, the humid air can be taken away quickly at a higher air flow rate, and the humidification amount is greater than the humidification amount at a lower air flow rate.

[0116] Therefore, when adjusting the humidification mode of the humidification unit 2, the control unit 4 can adjust the humidification amount of the humidification unit 2 by adjusting at least one of the water supply to the humidification component 21 and the air flow rate flowing through the humidification component 21. As described above, the control unit 4 can also adjust the humidification amount of the humidification unit 2 by adjusting the fresh air introduction amount of the ventilation unit 1.

[0117] In the above embodiments, the humidification component 21 using a moisture permeable membrane for humidification is described in detail as an example. Of course, this is only an exemplary description. The present invention is not limited to moisture permeable membrane humidification, but is also applicable to humidification methods such as spray humidification and ultrasonic humidification.

[0118] As an embodiment, the humidification mode of the humidification unit 2 includes a first humidification mode and a second humidification mode. The control unit 4 controls the humidity detection value H detected by the detection unit 3. N With humidity preset value H Y The comparison result controls the humidification unit 2 to execute the first humidification mode or the second humidification mode.

[0119] Humidity preset value H Y Including the first preset value H Y1 and the second preset value H Y2 , the second preset value H Y2 Greater than the first preset value H Y1 The first preset value H Y1 It can be set to the lowest humidity value of the humidity comfort level felt by the human body (for example, 30%). The second preset value H Y2The humidity value can be set to the upper limit of the humidity comfort level felt by the human body (for example, 60%). The control unit 4 can detect the humidity value H according to the humidity detection value H. N With the second preset value H Y2 and the first preset value H Y1 The humidification mode of the humidification unit 2 is adjusted based on the comparison result.

[0120] When the indoor humidity is low, the first humidification mode may be executed. In the first humidification mode, the control unit 4 increases at least one of the water supply to the humidification assembly 21 and the air flow rate passing through the humidification assembly 21 .

[0121] The indoor humidity value is low, and the indoor air is dry, which can easily cause human discomfort. The humidification unit 2 should be controlled to increase the humidification amount. At this time, the control unit 4 increases the water supply to the humidification component 21, and the water level in the humidification component 21 rises, so that the humidification component 21 is in the first height interval (high water level). At this time, the effective humidification area is the largest, which can increase the contact area between the air flowing through and the water, thereby increasing the humidification amount. Alternatively, the control unit 4 controls and increases the air flow rate flowing through the humidification component 21. The fast air flow rate can quickly bring out the water molecules in the humidification component 21 flowing through. The water molecules brought out in the same time increase, thereby increasing the humidification amount. Alternatively, the control unit 4 simultaneously increases the water supply to the humidification component 21 and the air flow rate flowing through the humidification component 21, so that rapid humidification can be achieved and the control accuracy can be improved.

[0122] When the indoor humidity is high, the second humidification mode may be performed, and the water supply amount of the humidification component 21 in the second humidification mode is less than that in the first humidification mode.

[0123] After the indoor humidity value reaches the humidity range that is more comfortable for the human body, the indoor air is at an appropriate humidity, and the humidifying unit 2 should be controlled to reduce the humidification amount. At this time, the control unit 4 reduces the water supply to the humidifying component 21, and the water level in the humidifying component 21 is lowered, so that the humidifying component 21 is in the second height interval (middle water level). This can reduce the contact area between the air flowing through and the water, which can not only maintain the indoor humidity value, but also reduce water consumption; or, the control unit 4 reduces the air flow rate flowing through the humidifying component 21. The slow air flow rate can reduce the water molecules carried out of the humidifying component 21. The water molecules carried out in the same time are reduced, thereby reducing the humidification amount; or the control unit 4 simultaneously reduces the water supply of the humidifying component 21 and the air flow rate flowing through the humidifying component 21, which can reduce the humidification amount, keep the indoor humidity within a comfortable humidity range, and improve the control accuracy.

[0124] The heating component 23 can heat the air flowing through the humidification component 21. The air is heated before entering the humidification component 21. The heated air enters the humidification component 21 and takes away the moisture in the humidification component 21, thereby humidifying the hot air. When the heated air flows through the humidification component 21, it can accelerate the evaporation of water molecules, improve humidification efficiency, and the temperature of the air finally blown out is also more comfortable (the higher the temperature, the faster the evaporation rate of water molecules, and the greater the humidity in the air.)

[0125] The heating component can also heat the air humidified by the humidifying unit 2, thereby increasing the temperature of the humid air.

[0126] The heating component can also heat the water entering the humidifying component 21. After the air flows through the heating component 21, it takes away the heated moisture, thereby increasing the temperature of the humid air. The higher the temperature, the faster the water molecules evaporate.

[0127] By heating the air flowing through the humidification component 21 and / or the water used for humidification, the temperature and humidity of the indoor air are regulated to ensure the indoor temperature and humidity comfort.

[0128] The heating element may also be a refrigerant heat exchanger. The refrigerant heat exchanger and the refrigerant circuit 51 of the air conditioning unit 5 (see Figure 1 The heating component heats the introduced air through the refrigerant circuit 51, and inputs the heated air into the humidification unit 2 to improve the humidification efficiency of the humidification module.

[0129] like Figure 1 As shown, the humidification unit 2 is linked with the air conditioning unit 5 to ensure the comfort of indoor temperature and humidity and the performance of the air handling systems 100, 101, and 102. At the same time, the refrigerant circuit 51 of the air conditioning unit 5 is used to recover heat and save energy.

[0130] The present invention also provides a control method for the above-mentioned air treatment systems 100, 101, 102, which is described in detail below.

[0131] Figure 6 FIG. 1 is a flow chart of an air handling system control method 110 according to a specific embodiment of the present invention.

[0132] like Figure 6 As shown, in the control method 110, the following steps are included:

[0133] Step S1, the detection unit 3 detects the humidity detection value H of the indoor air N .

[0134] The detection unit 3 detects the indoor air humidity in real time and generates the detected air humidity detection value H Nsent to the control unit 4.

[0135] Step S2: the control unit 4 converts the humidity detection value H detected by the detection unit 3 into N With humidity preset value H Y Make a comparison.

[0136] The control unit 4 receives the humidity detection value H transmitted by the detection unit 3. N Then compare it with the humidity preset value H Y Compare the current indoor humidity to determine whether it is at a comfortable level for human body. Humidity preset value H Y It is the humidity value within the most suitable humidity range for the human body.

[0137] Step S3 , according to the comparison result, the control unit 4 adjusts the operation mode of the humidification unit 2 , or adjusts the amount of fresh air introduced into the ventilation unit 1 .

[0138] The control unit 4 detects the humidity according to the value H N With humidity preset value H Y The comparison result is used to adjust the humidification amount of the humidification unit 2, so that the indoor humidity value is maintained at the humidity preset value H Y within the range to improve human comfort.

[0139] Figure 7 FIG. 1 is a flow chart of an air handling system control method 120 according to another specific embodiment of the present invention.

[0140] like Figure 7 As shown, in the control method 120,

[0141] Step S61, the detection unit 3 detects the indoor air humidity detection value H N ;

[0142] Step S62: the control unit 4 converts the humidity detection value H detected by the detection unit 3 into N With humidity preset value H Y Make comparisons;

[0143] In step S63 , the control unit 4 adjusts the humidification mode of the humidification unit 2 or adjusts the amount of fresh air introduced into the ventilation unit 1 by adjusting the water supply of the humidification component 21 or adjusting the air flow rate flowing through the humidification component 21 .

[0144] Figure 8 FIG. 1 is a flow chart of an air handling system control method 130 according to another specific embodiment of the present invention.

[0145] like Figure 8 As shown, the humidification mode of the humidification unit 2 includes a first humidification mode and a second humidification mode. The control unit 4 controls the humidity detection value H detected by the detection unit 3.N With humidity preset value H Y The humidification unit 2 is controlled to execute the first humidification mode or the second humidification mode according to the comparison result.

[0146] like Figure 8 As shown, in the control method 130,

[0147] Step S71, the detection unit 3 detects the indoor air humidity detection value H N .

[0148] Step S72: the control unit 4 converts the humidity detection value H detected by the detection unit 3 into N With humidity preset value H Y Make a comparison.

[0149] The indoor humidity detection value H detected by the detection unit 3 N Less than or equal to the first preset value H Y1 When the indoor humidity detection value H detected by the detection unit 3 is N Greater than the second preset value H Y2 When the indoor humidity detection value H detected by the detection unit 3 is N Greater than the first preset value H Y1 and is less than the second preset value H Y2 , proceed to step S75.

[0150] In step S73 , the control unit 4 controls the humidifying unit 2 to execute the first humidifying mode. In the first humidifying mode, the control unit 4 controls at least one of increasing the water supply of the humidifying component 21 and increasing the air flow rate passing through the humidifying component 21 .

[0151] Indoor humidity detection value H N Less than or equal to the first preset value H Y1 (e.g. 30%), the first preset value H Y1It can be pre-set in the control logic of the control unit 4, or it can be manually set by the user. At this time, the indoor humidity value is low, the indoor air is dry, and it is easy to cause discomfort to the human body. The humidification unit 2 should be controlled to increase the humidification amount. At this time, the control unit 4 controls to increase the water supply of the humidification component 2, and the water level in the humidification component 21 rises, so that the humidification component 21 is in the first height interval (high water level). Specifically, the water level of the wet film humidification component can be full of water to maximize the humidification area of ​​the humidification component, which can increase the contact area between the air flowing through and the water, thereby increasing the humidification amount; or, the control unit 4 controls to increase the air flow rate flowing through the humidification component 21. The fast air flow rate can quickly bring out the water molecules in the humidification component 21 flowing through. The water molecules brought out in the same time increase, thereby increasing the humidification amount; or the control unit 4 simultaneously increases the water supply of the humidification component 21 and the air flow rate flowing through the humidification component 21, so that rapid humidification can be achieved and control accuracy can be improved.

[0152] When the indoor humidity is very low, the humidification component 21 can be placed in the first height range (high water level) while increasing the air flow rate, which can further improve the humidification efficiency and achieve rapid humidification.

[0153] In step S74, the control unit 4 controls the humidification unit 2 to reduce the humidification amount or stop humidification, so as to maintain the indoor humidity within a comfortable range.

[0154] Indoor humidity detection value H N Greater than the second preset value H Y2 (e.g. 60%), the second preset value H Y2 It can be pre-set in the control logic of the control unit 4, or it can be manually set by the user. At this time, the indoor humidity value is high, exceeding the indoor humidity comfort range, and the human body feels uncomfortable. The humidification unit 2 should be controlled to stop humidification to prevent excessive humidification, avoid condensation in the room and the air supply duct, and reduce the indoor humidity value to a reasonable range to improve the indoor humidity comfort.

[0155] In step S75 , the control unit 4 controls the humidifying unit 2 to execute the second humidifying mode. In the second humidifying mode, the water supply amount of the humidifying component 21 is less than the water supply amount in the first humidifying mode.

[0156] Indoor humidity detection value H N Greater than the first preset value H Y1 and is less than the second preset value H Y2At this time, the indoor humidity value reaches the humidity range that is more comfortable for the human body, and the indoor air is at a suitable humidity. The humidifying unit 2 should be controlled to reduce the humidification amount. At this time, the control unit 4 controls to reduce the water supply of the humidifying component 2, and the water level in the humidifying component 21 is lowered, so that the humidifying component 21 is in the second height interval (middle water level), which can reduce the contact area between the air flowing through and the water, thereby reducing the humidification amount; or, the control unit 4 controls to reduce the air flow rate flowing through the humidifying component 21. The slow air flow rate can reduce the water molecules carried out of the humidifying component 21. The water molecules carried out in the same time are reduced, thereby reducing the humidification amount; or the control unit 4 simultaneously reduces the water supply of the humidifying component 21 and the air flow rate flowing through the humidifying component 21, which can reduce the humidification amount, keep the indoor humidity within a comfortable humidity range, and improve the control accuracy.

[0157] Fig. 9 FIG. 1 is a flow chart of an air handling system control method 140 according to another specific embodiment of the present invention.

[0158] like Fig. 9 As shown, the control method 140 includes the following steps.

[0159] Step S81, the detection unit 3 detects the indoor air humidity detection value H N .

[0160] Step S82: the control unit 4 converts the humidity detection value H detected by the detection unit 3 into N With humidity preset value H Y Make a comparison.

[0161] When the indoor humidity detection value H N Less than or equal to the first preset value H Y1 When the indoor humidity detection value H detected by the detection unit 3 is N Greater than the first preset value H Y1 , proceed to step S84.

[0162] In step S83 , the control unit 4 controls the humidifying unit 2 to execute the first humidifying mode.

[0163] Step S84: the detection unit 3 detects the indoor air quality and obtains the indoor air quality detection value Q N , according to the indoor air quality test value Q N , determine the operation mode of the ventilation unit 1 and the humidification mode of the humidification unit 2.

[0164] Indoor air quality test value Q N Indicates the degree of indoor air pollution, which may include carbon dioxide (CO2) concentration, inhalable particulate matter (PM2.5) concentration, etc.

[0165] Step S85: the control unit 4 converts the indoor air quality detection value Q detected by the detection unit 3 into N The air quality preset value Q Y When the indoor air quality detection value Q N Greater than or equal to the preset air quality value Q Y When the indoor air quality detection value Q N Less than the preset air quality value Q Y , proceed to step S87.

[0166] Step S86: When the indoor air quality detection value Q N Greater than or equal to the preset air quality value Q Y When the indoor air is exhausted, the control unit 4 controls the ventilation unit 1 to introduce fresh air and / or exhaust the indoor air, and controls the humidification unit 2 to execute the second humidification mode.

[0167] When the indoor air quality detection value Q N Greater than or equal to the preset air quality value Q Y When the concentration of carbon dioxide (CO2) exceeds the standard, the indoor air quality deteriorates. Usually, the comfortable range of CO2 concentration is 400-800ppm. When the CO2 concentration is greater than 1000ppm, fresh air needs to be introduced. At this time, the control unit 4 controls the ventilation unit 1 to execute the fresh air introduction mode P1 or the exhaust mode P2.

[0168] When the ventilation unit 2 performs rapid fresh air introduction, it also exhausts air to the outside, that is, the ventilation unit 1 simultaneously executes the fresh air introduction mode P1 and the exhaust mode P2, and the exhaust will discharge the humidified air, causing energy waste. At this time, in order to save energy, the humidification unit 2 is controlled to execute the second humidification mode to humidify the water level therein, thereby avoiding waste.

[0169] Step S87, when the indoor air quality detection value Q N Less than the preset air quality value Q Y When the indoor CO2 concentration is within a comfortable range, there is no need to introduce fresh air, and the humidification unit 2 is controlled to execute the second humidification mode.

[0170] In the above embodiment, the operation mode of the ventilation unit 1 and the humidification mode of the humidification unit 2 are not set in advance, but the control unit 4 automatically adjusts the operation of the ventilation unit 1 and the humidification unit 2 according to the detection result of the detection unit 3. Of course, the user can also set the operation mode of the ventilation unit 1 or the humidification mode of the humidification unit 2 in advance, and the control unit 4 controls and adjusts the operation of the other unset unit according to the user's setting, so as to make the indoor air have a higher degree of comfort.

[0172] like Fig.10 As shown, in the control method 150 , the ventilation unit 1 is set by the user to the fresh air introduction mode P1 for introducing fresh air. At this time, the control unit 4 controls and adjusts the operation of the humidification unit 2 according to the operation mode of the ventilation unit 1 .

[0173] The control method 150 includes the following steps.

[0174] In step S9 , the ventilation unit 1 executes the fresh air introduction mode P1 , and introduces air from the outside into the ventilation unit 1 to form fresh air, which is then sent to the humidification unit 2 .

[0175] Step S91, the detection unit 3 detects the indoor air humidity detection value H N .

[0176] Step S92: the control unit 4 converts the humidity detection value H detected by the detection unit 3 into N With humidity preset value H Y For comparison,

[0177] When the indoor humidity detection value H detected by the detection unit 3 N Less than or equal to the first preset value H Y1 When the process goes to step S93, the control unit 4 controls the humidification unit 2 to perform the first humidification mode;

[0178] When the indoor humidity detection value H detected by the detection unit 3 N Greater than the second preset value H Y2 When , step S94 is executed, the control unit 4 controls the humidification unit 2 to stop humidification;

[0179] When the indoor humidity detection value H detected by the detection unit 3 N Greater than the first preset value H Y1 and is less than the second preset value H Y2 When the humidification unit 2 is in the second humidification mode, step S95 is executed, and the control unit 4 controls the humidification unit 2 to execute the second humidification mode.

[0180] In the above embodiment, when the user has set the ventilation unit 1 to execute the fresh air mode P1, the control unit 4 controls the humidification unit 2 to be linked with the ventilation unit 1 to ensure the indoor humidity comfort level.

[0181] When the ventilation unit 1 introduces fresh air, the humidification mode of the humidification unit 2 is adjusted to reduce water replenishment and improve humidification efficiency.

[0186] Step S101, the detection unit 3 detects the outdoor environmental humidity and obtains the outdoor environmental humidity detection value H W .

[0187] Step S102: the control unit 4 converts the outdoor environment humidity detection value H detected by the detection unit 3 into W With humidity preset value H Y Make a comparison.

[0188] Step S103: the control unit 4 detects the outdoor humidity according to the value H W Adjust the amount of fresh air introduced into the ventilation unit 1.

[0189] Outdoor humidity detection value H W When the humidity of the outdoor air is high, the control unit 4 can adjust the ventilation unit 1 to increase the amount of fresh air introduced, and use the humidity of the outdoor air to increase the humidification speed, humidify quickly, and save energy.

[0190] Outdoor humidity detection value H W When the humidity is low, the outdoor air humidity is low, and the control unit 4 can adjust the ventilation unit 1 to reduce the amount of fresh air introduced or not introduce fresh air to prevent dry fresh air from affecting the indoor humidity comfort.

[0191] After step S103, Figure 8 Steps S71-S74 are the same, and repeated description is omitted here.

At this time, the control unit 4 controls and adjusts the operation of the humidification unit 2 according to the operation mode of the ventilation unit 1 .

[0194] Specifically, the control method 170 includes the following steps.

[0195] In step S110, the ventilation unit 1 executes the exhaust mode P2, introducing the indoor air into the ventilation unit 1 and then exhausting it to the outside.

[0196] As the indoor air is exhausted, the indoor humidity value changes and indoor humidity adjustment is required to maintain the indoor humidity comfort level.

[0197] After the ventilation unit 1 executes the exhaust mode P2, the detection unit 3 detects the indoor air humidity, and the control unit 4 adjusts the indoor humidity according to the indoor humidity detection value H N The humidification unit 2 is adjusted to perform the first humidification mode or the second humidification mode. The control unit 4 controls the operation mode of the humidification unit 2 to be the same as Figure 7 The control method is the same as in .

[0198] When the user has set the ventilation unit 1 to execute the exhaust mode P2, the control unit 4 controls the humidification unit 2 to be linked with the ventilation unit 1 to ensure the indoor humidity comfort level.

[0199] When the ventilation unit 1 is exhausting air, the water level of the humidifying component 21 is located at the middle water level, and slow humidification is performed to ensure the comfort of indoor humidity, while reducing moisture loss and saving energy.

[0200] After step S110, Figure 8 Steps S71-S74 are the same, and repeated description is omitted here.

[0201] In one embodiment, the control unit 4 adjusts the humidification mode of the humidification unit 2 according to the operation mode of the air conditioning unit 5.
