[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.

[0069] 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.

[0070] Being in a dry environment for a long time can cause people to feel dry mouth, dry eyes, chapped skin and other discomfort symptoms. In addition, in a warm and dry environment, 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 immunity.

[0071] 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 and humidification, and through the control system, realizes the joint adjustment of ventilation and humidification modes according to the indoor air environment, improves the indoor dry environment, enhances the comfort of the indoor environment, and reduces the infectivity of pathogens.

[0072] Figure 1 The figure is a schematic diagram of an air treatment system according to an embodiment of the present invention.

[0073] 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.

[0074] 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 .

[0075] 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.

[0076] The ventilation unit 1 and the humidification unit 2 are sequentially arranged on the air supply path. The air distribution module 6 is connected to the humidification unit 2. The air humidified by the humidification unit 2 is supplied to the air distribution module 6. The multiple air outlets of the air distribution module 6 are respectively connected to the multiple air supply outlets 7. The multiple air supply outlets 7 are located in multiple areas of the room to supply air to the multiple areas respectively.

[0077] 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 the 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 through the paper heat exchanger; the ventilation unit 1 may not be provided with a paper heat exchanger. In order to ensure the cleanliness of the air finally delivered to the room, a filter element can 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., and specific chemical components include carbon dioxide (CO2), formaldehyde, odorous substances, etc.; thereby improving the air quality.

[0078] 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 discharged from the humidifying unit 2 has a certain humidity, thereby improving the dry environment in the room and enhancing the comfort of the indoor environment.

[0079] 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 the multiple areas respectively. All the air outlets 61 can be used, and some of the air outlets 61 can also be used as needed.

[0080] The number of air outlets 61 can be designed according to actual needs, and the ratio of air output by multiple air outlets 61 can be set according to actual needs. For example, the air flow rates of various air outlets 61 are the same or different.

[0081] The air pipeline 140 is an air inlet pipe, and each air pipeline 140 corresponds to a different indoor area.

[0082] like 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.

[0083] Figure 2 FIG. 1 is a system schematic diagram of an air treatment system 101 according to another embodiment of the present invention.

[0084] like Figure 2As 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, but the difference from the air handling system 100 is that the air handling system 101 does not have the air distribution module 6, and a plurality of air valves 150 are arranged 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 .

[0085] 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. In addition, the number of the air outlets 121 can be designed according to actual needs.

[0086] Figure 3 FIG. 1 is a system schematic diagram of an air treatment system 102 according to another embodiment of the present invention.

[0087] Figure 3 The structure of the air handling system 102 is shown 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 .

[0088] in addition, Figure 2 and Figure 3 In, with Figure 1 The same content can be referred to Figure 1 The relevant instructions will not be repeated.

[0089] Figure 2 and Figure 3 In the figure, 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 setting the air valves 150 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. In addition, compared with the air treatment system 101, since there is no need to set the air distribution module 6, the system structure can be further simplified.

[0090] The detection unit 3 is a unit for detecting the air environment, including one or more sensors of temperature and humidity sensors, CO2 sensors, PM2.5 sensors, VOC sensors, TVOC sensors, formaldehyde sensors, and odor sensors, and can detect indoor air humidity values, outdoor air humidity values, indoor air quality, outdoor air quality, etc. The detection unit 3 can be set inside the air treatment system 100, or can be independently set indoors.

[0091] 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 1.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] The control unit 4 is the control center of the air treatment system 100, 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).

[0097] 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.

[0098] Humidity preset value H YIt 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.

[0099] The control unit 4 converts the indoor humidity detection value H detected by the detection unit 3 into N With humidity preset value H Y A comparison is performed, and the humidification mode of the humidification unit 2 and the operation mode of the ventilation unit 1 are adjusted according to the comparison result.

[0100] The control unit 4 detects the humidity according to the value H N With humidity preset value H Y The humidification mode of the humidification unit 2 is adjusted based on the comparison result, so that the indoor humidity value is maintained within the range of humidity suitable for the human body, thereby improving the comfort of the human body.

[0101] Select the appropriate humidification mode according to the indoor humidity value. There are various humidification modes to ensure the indoor humidity comfort while saving water.

[0102] Furthermore, the control unit 4 determines the humidity according to the humidity detection value H N With humidity preset value H Y The operation mode of the ventilation unit 1 is adjusted according to the comparison result. In different humidification modes, the operation mode of the ventilation unit 1 can be different to ensure the overall performance of the air treatment system and reduce energy waste.

[0103] Figure 4 It is a schematic diagram of a ventilation unit 1 according to a specific embodiment of the present invention.

[0104] like Figure 4As 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. An air supply fan 15 is provided in the ventilation unit 1. 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 air supply fan 15 sends the fresh air into the humidification unit 2 through the air supply port 12, forming a fresh air introduction mode P1 of the ventilation unit 1. In the fresh air introduction mode P1, the ventilation unit 1 introduces air from the outside and transports it to the humidification unit 2 through the ventilation unit 1.

[0105] The return air port 13 draws in air from the room and exhausts it to the outside through the exhaust port 14, forming an exhaust mode P2. In the exhaust mode P2, the ventilation unit 1 draws in air from the room and exhausts it to the outside through the ventilation unit 1.

[0106] 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 an internal circulation mode P3. In the internal circulation mode P3, the ventilation unit 1 introduces air from the room, and the indoor air is transported to the humidification unit 2 through the ventilation unit 1, and then flows back to the room after being humidified by the humidification unit 2.

[0107] The detection unit 3 may also be arranged at the return air vent 13. According to the arrangement of the air handling system 100, the return air vent 13 may be provided with one for centrally introducing indoor air, or may be provided with multiple return air vents 13, which are respectively arranged in multiple areas of the room, such as multiple rooms, to introduce air in each area.

[0108] The operation mode of the ventilation unit 1 also includes a strong air supply mode P4, in which the ventilation unit 1 delivers a large amount of air to the room and a large air flow rate. The air supply fan 15 operates at the maximum gear.

[0109] Figure 5 It is a schematic diagram of a humidifying unit 2 according to a specific embodiment of the present invention.

[0110] like Figure 5 As shown, an air flow path F1 is formed between the air inlet 24 and the air outlet 25 of the humidifying unit 2. A temperature regulating device 23 and a humidifying component 21 are sequentially arranged from the air inlet 24 to the air outlet 25. 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 air passes through the moisture permeable membrane in the humidifying component 21, taking away the water molecules therein, so that the air is humidified. 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.

[0111] The temperature adjustment device 23 is a heat exchanger, and is connected to the air conditioning unit 5 through a refrigerant pipe to form a refrigerant circuit 51. The heating component 23 may also be an electric heater.

[0112] The humidifying unit 2 supplies water to the humidifying assembly 21 through a water storage component, and the water storage component can be a water tank 22 arranged in the humidifying unit 2, or can be a water supply pipe connected to the outside. The water supply amount of the water storage component to the humidifying assembly 21 is adjustable. When the water supply amount to the humidifying assembly 21 is large, the moisture permeable membrane of the humidifying assembly 21 will absorb more water, so that the humidifying assembly 21 has a higher water level. When the water supply amount 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.

[0113] 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.

[0114] Figure 6 A schematic diagram of a water tank according to a specific embodiment of the present invention.

[0115] like Figure 6 As shown, a water level detection component 221 is provided in the water tank 22, and the water level detection component 221 can detect the water level in the water tank 22. The control unit 4 adjusts the water level of the humidifying component 21 according to the water level in the water tank 22, thereby adjusting the humidification mode and humidification amount of the humidifying unit 2. The water level detection component 221 in the water tank 22 is used to judge and adjust the water level of the humidifying component 21, which has a simple structure and high control accuracy.

[0116] The water level detection component 221 can use a float switch. Since the water tank 22 and the humidification component 21 are connected, and the highest point of the water level in the water tank 22 is roughly the same as the highest point of the water level in the humidification component 21, the water level of the water tank 22 is the water level of the humidification component 21, and the water level of the humidification component 21 can be detected by the float switch in the water tank 22. The water level of the humidification component can be adjusted by adjusting the three-way valve.

[0117] When the humidifying component 21 is full of water, the water flow of the humidifying component 21 is 100%. When the water level of the humidifying component 21 is 100-88%, it is a high water level in the first height interval of the water level. When the water level of the humidifying component 21 is 88%-72%, it is a middle water level in the second height interval of the water level. When the water level of the humidifying component 21 is 72%-60%, it is a low water level in 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.

[0118] When air (fresh air) flows through the moisture permeable membrane of the humidifying component 21, water molecules are taken out, thereby increasing the humidity of the air flowing through. Under the same air flow rate, when the humidifying component 21 has a higher water level, since the air has a larger contact area with the water molecules in the moisture permeable membrane, the humidification amount when the humidifying component 21 has a higher water level is greater than the humidification amount when the humidifying component 21 has a lower water level.

[0119] 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 the water level of the humidification component 21, thereby realizing the conversion between different humidification modes.

[0120] An air supply fan (not shown) may be provided in the humidifying unit 2, or the air supply fan 15 of the ventilation unit 1 or a fan in the air supply pipeline may be used to deliver the humidified air into the room. The humidifying unit 2 may also be provided with a bypass path, and the bypass paths correspond to a plurality of air supply ports 7, respectively, so that each area may be humidified according to the humidification requirements of each area, or some areas may be humidified and some areas may not be humidified.

[0121] 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.

[0122] As an embodiment, the humidification mode of the humidification unit 2 includes a first humidification mode F1 and a second humidification mode F2. The control unit 4 determines the humidity detection value H detected by the detection unit 3. N With humidity preset value H Y Based on the comparison result, the humidification unit 2 is controlled to execute the first humidification mode F1 or the second humidification mode F2, and the ventilation unit 1 is controlled to execute the fresh air introduction mode P1 or the internal circulation mode P3.

[0123] In the first humidification mode F1, the humidification amount of the humidification unit 2 is the first humidification amount f1, and in the second humidification mode F2, the humidification amount of the humidification unit 2 is the second humidification amount f2, and the second humidification amount f2 is greater than the first humidification amount f1, that is, the humidification intensity of the second humidification mode F2 is greater than the humidification intensity of the first humidification mode F1, and the second humidification mode F2 can humidify the air faster than the first humidification mode F1. The second humidification mode F2 can be called strong humidification, and the first humidification mode F1 can be called ordinary humidification. Therefore, when the indoor humidity conditions are different, the first humidification mode F1 or the second humidification mode F2 can be selected according to the situation, and the first humidification amount f1 and the second humidification amount f2 are both adjustable within their respective ranges.

[0124] With 350 large capacity (air supply volume 350m 3 / h) as an example: under the working condition of water temperature 20℃, humidification at full water level, the humidification amount is 2920.2g / h, that is, the maximum value of the second humidification amount f2; humidification at medium water level, the humidification amount is 2511.8g / h, that is, the maximum value of the first humidification amount f1.

[0125] When the indoor humidity is low, the second humidification mode F2 may be executed. In the second humidification mode F2, the control unit 4 controls to increase the water level of the humidification component 2.

[0126] The indoor humidity value is low and the indoor air is dry, which can easily cause human discomfort. At this time, the humidification unit 2 can be controlled to operate in the second humidification mode F2 to increase the humidification amount. Specifically, the control unit 4 increases the water supply of the humidification component 2, and the water level in the humidification component 21 rises, so that the water level of the humidification component 21 is in the first height range (high water level). This can increase the contact area between the flowing air and the water, increase the humidification amount, and make the humidification unit 2 humidify with the second humidification amount f2.

[0127] When the indoor humidity is high, the first humidification mode F1 may be performed.

[0128] When the indoor humidity value reaches the humidity range that is more comfortable for the human body, the indoor air is at an appropriate humidity. At this time, the humidification unit 2 can be controlled to reduce the humidification amount. Specifically, the control unit 4 reduces the water supply of the humidification component 2, and the water level in the humidification component 21 is lowered, so that the water level of the humidification component 21 is in the second height interval (middle water level). This can reduce the contact area between the flowing air and the water, reduce the humidification amount, and make the humidification unit 2 humidify at the first humidification amount f1.

[0129] The temperature regulating device 23 may be a heating component, which heats the air and / or humidifying water flowing through the humidifying component 21. The heating component may be a heat exchanger or an electric heater.

[0130] The heating component can heat the air flowing through the humidifying component 21, and heat the air before the air enters the humidifying component 21. The heated air enters the humidifying component 21 and takes away the moisture in the humidifying component 21 to achieve humidification. The heating component can also heat the air humidified by the humidifying unit 2 to increase the temperature of the humid air.

[0131] 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 and increases the temperature of the humid air.

[0132] By heating the air and / or water, the temperature and humidity of the indoor air can be adjusted to ensure the indoor temperature and humidity comfort.

[0133] 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.

[0134] 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 to ensure the performance of the air treatment system 100 .

[0135] The present invention further provides a control method for the above-mentioned air treatment systems 100, 101, 102, and the control method is described in detail below.

[0136] Figure 7 FIG. 1 is a flow chart of an air handling system control method 110 according to a specific embodiment of the present invention.

[0137] like Figure 7 As shown, the control method 110 includes the following steps:

[0138] Step S1, the detection unit 3 detects the humidity detection value H of the indoor air N .

[0139] The detection unit 3 detects the indoor air humidity in real time and generates the detected air humidity detection value H N sent to the control unit 4.

[0140] 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.

[0141] 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 HY By comparison, it can be determined whether the current indoor humidity is maintained at a humidity comfort level suitable for the human body.

[0142] Step S3 , according to the comparison result, the control unit 4 adjusts the humidification mode of the humidification unit 2 and the operation mode of the ventilation unit 1 .

[0143] The control unit 4 detects the humidity according to the value H N With humidity preset value H Y The comparison result adjusts the humidification mode of the humidification unit 2 to keep the indoor humidity value at the preset humidity value H Y The humidification mode is selected according to the indoor humidity value. There are various humidification modes to ensure the indoor humidity comfort while saving water.

[0144] Furthermore, the control unit 4 determines the humidity according to the humidity detection value H N With humidity preset value H Y The operation mode of the ventilation unit 1 is adjusted based on the comparison results. Different humidification modes are combined with different operation modes of the ventilation unit 1 to ensure the overall performance of the system and reduce energy waste.

[0145] Figure 8 FIG. 1 is a flow chart of an air handling system control method 120 according to another specific embodiment of the present invention.

[0146] like Figure 8 As shown, the control method 120 includes the following steps:

[0147] Step S61, the detection unit 3 detects the indoor air humidity detection value H N .

[0148] 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 When the indoor humidity detection value H detected by the detection unit 3 is N Greater than or equal to the humidity preset value H Y When the indoor humidity detection value H N Less than the humidity preset value H Y , execute step S64.

[0149] In step S63, when the indoor humidity detection value H detected by the detection unit 3 is N Greater than or equal to the humidity preset value H Y When the humidification unit 2 is in the first humidification mode F1, the control unit 4 controls the ventilation unit 1 to execute the fresh air introduction mode P1 or the internal circulation mode P3.

[0150] Indoor humidity detection value H N Greater than or equal to the humidity preset value H Y When the indoor humidity value reaches the humidity range that is more comfortable for the human body, the indoor air is at a suitable humidity, so the humidification unit 2 is controlled to reduce the humidification amount. Specifically, the humidification unit 2 is controlled to execute the first humidification mode F1, and the water level in the humidification component 21 is lowered so that the water level of the humidification component 21 is in the second height interval (middle water level), thereby reducing the humidification amount. The humidification amount of the humidification unit 2 is reduced to the first humidification amount f1.

[0151] At the same time, the control unit 4 can control the ventilation unit 1 to execute the fresh air introduction mode P1 or the internal circulation mode P3.

[0152] When the indoor humidity value is high, the ventilation unit 1 is controlled to execute the fresh air introduction mode P1 to introduce fresh air, thereby improving the air quality while ensuring the indoor humidity. Alternatively, the ventilation unit 1 is controlled to execute the internal circulation mode P3 to return the indoor air to the room through the ventilation unit 1, thereby preventing the loss of indoor moisture and saving water.

[0153] In step S64, when the indoor humidity detection value H N Less than the humidity preset value H Y When the humidification unit 2 is in the second humidification mode F2, the control unit 4 controls the ventilation unit 1 to perform the internal circulation mode P3.

[0154] Indoor humidity detection value H N Less than the humidity preset value H Y When the indoor humidity value is low, the indoor air is dry, which can easily cause discomfort to the human body. Therefore, the humidification unit 2 is controlled to increase the humidification amount. Specifically, the control unit 4 controls the humidification unit 2 to execute the second humidification mode F2, and the water level in the humidification component 21 rises, so that the water level of the humidification component 21 is in the first height range (high water level), thereby increasing the humidification amount. The humidification amount of the humidification unit 2 is increased to the second humidification amount f2.

[0155] At the same time, the control unit 4 controls the ventilation unit 1 to execute the internal circulation mode P3 to prevent moisture loss, save water, and improve humidification efficiency.

[0156] In the above embodiment, the control unit 4 selects a suitable humidification mode according to the indoor humidity value. N Less than the humidity preset value H Y When the indoor humidity detection value H N Greater than or equal to the humidity preset value H Y When the humidity is low, the humidification unit 2 is controlled to execute the first humidification mode F1 to reduce the humidification amount; the humidification modes are diverse, which ensures the indoor humidity comfort while saving water.

[0157] Furthermore, the control unit 4 determines the humidity according to the humidity detection value H N With humidity preset value H Y The operation mode of the ventilation unit 1 is adjusted according to the comparison result. In different humidification modes, the operation mode of the ventilation unit 1 is different, which ensures the overall performance of the system and reduces energy waste.

[0158] Fig. 9 FIG. 1 is a flow chart of an air handling system control method 130 according to another specific embodiment of the present invention.

[0159] like Fig. 9 As shown, the control method 130 includes the following steps.

[0160] Step S71, the detection unit 3 detects the indoor air humidity detection value H N .

[0161] 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 When the indoor humidity detection value H N Less than the humidity preset value H Y When the indoor humidity detection value H detected by the detection unit 3 is N Greater than or equal to the humidity preset value H Y When the indoor air quality detection step S74 is entered, the indoor air quality detection value Q N , determine the operating mode of the ventilation unit 1.

[0162] In step S73, when the indoor humidity detection value H N Less than the humidity preset value H Y When the humidification unit 2 is in the second humidification mode F2, the control unit 4 controls the ventilation unit 1 to perform the internal circulation mode P3.

[0163] In step S74, the control unit 4 controls the humidification unit 2 to perform the first humidification mode F1, and the detection unit 3 detects the indoor air quality to obtain the indoor air quality detection value Q N ; Indoor air quality test value Q N It can indicate the degree of indoor air pollution, including carbon dioxide (CO2) concentration, inhalable particulate matter (PM2.5) concentration, etc.

[0164] Step S75, 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 YWhen the indoor air quality detection value Q N Less than the preset air quality value Q Y , proceed to step S77.

[0165] In step S76, when the indoor air quality detection value Q N Greater than or equal to the preset air quality value Q Y When the air is in the fresh air mode P1, the control unit 4 controls the ventilation unit 1 to execute the fresh air mode P1.

[0166] When the indoor air quality detection value Q N Greater than or equal to the preset air quality value Q Y For example, when the concentration of carbon dioxide (CO2) exceeds the standard, the indoor air quality deteriorates. Usually, the appropriate 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 to improve the indoor air quality.

[0167] In step S77, 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 an appropriate range, the control unit 4 controls the ventilation unit 1 to execute the fresh air introduction mode P1 or the internal circulation mode P3. Executing the fresh air introduction mode P1 can continuously improve the indoor air quality and maintain the indoor air comfort. Executing the internal circulation mode P3 can save energy.

[0168] In this embodiment, the control unit 4 detects the air quality value Q N The air quality preset value Q Y The comparison result determines the operation mode of the ventilation unit 1, while ensuring the indoor humidity comfort level and improving the indoor air quality.

[0169] 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.

[0170] Fig.10 FIG. 1 is a flow chart of an air handling system control method 140 according to another specific embodiment of the present invention.

[0171] like Fig.10As shown in the control method 140, when the ventilation unit 1 executes the fresh air introduction mode P1 for introducing fresh air, the outdoor environment humidity is detected, and the outdoor environment humidity detection value H is set according to the outdoor environment humidity detection value H. W Adjust the fresh air introduction amount of the ventilation unit 1, and further, the control unit 4 adjusts the fresh air introduction amount according to the outdoor environment humidity detection value H w , and the amount of fresh air introduced into the ventilation unit 1, and adjust the humidification amount of the humidification unit 2.

[0172] Specifically, the control method 140 includes the following steps:

[0173] In step S8 , the ventilation unit 1 executes the fresh air introduction mode P1 , introduces air from the outside into the ventilation unit 1 to form fresh air, and then sends it to the humidification unit 2 .

[0174] Step S81: the detection unit 3 detects the outdoor environment humidity and obtains the outdoor environment humidity detection value H W .

[0175] Step S82: 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 When the outdoor humidity detection value H W Greater than or equal to the humidity preset value H Y When the outdoor humidity detection value H W Less than the humidity preset value H Y , execute step S84.

[0176] In step S83, the outdoor environment humidity detection value H W Greater than or equal to the humidity preset value H Y That is, when the outdoor air humidity is high, the control unit 4 can adjust the ventilation unit 1 to increase the amount of fresh air introduced, utilize the outdoor air humidity to increase the humidification speed, improve the humidification efficiency, and save energy.

[0177] In step S84, the outdoor environment humidity detection value H W Less than the humidity preset value H Y That is, when the outdoor air humidity is low, the control unit 4 can adjust the ventilation unit 1 to reduce the amount of fresh air introduced to prevent the dry fresh air from lowering the indoor humidity, thereby ensuring the comfort of the fresh air and reducing the impact of the dry outdoor air on the indoor humidity.

[0178] After step S83, execute step S85.

[0179] Since the outdoor air humidity is high, the amount of fresh air introduced by the ventilation unit 1 increases. In step S85, the humidification amount of the humidification unit 2 is reduced, and the outdoor air humidity is used to accelerate indoor humidification, which is energy-saving and environmentally friendly and can also avoid over-humidification.

[0180] After executing step S84, execute step S86.

[0181] Since the outdoor air humidity is low, the amount of fresh air introduced by the ventilation unit 2 is reduced. In step S86, the humidification amount of the humidification unit 2 is increased to ensure the indoor humidity comfort.

[0182] As described above, the control unit 4 controls the humidification unit 2 to be linked with the ventilation unit 1. Regardless of whether the humidification unit 2 is in the first humidification mode F1 or the second humidification mode F2, the humidification unit 2 is set to the first humidification mode F1 or the second humidification mode F2 according to the outdoor environment humidity detection value H w The amount of fresh air introduced by the ventilation unit 1 can adjust the humidification amount of the humidification unit 2 to the best level to ensure the indoor humidity comfort.

[0183] Fig.11 FIG. 1 is a flow chart of an air handling system control method 150 according to another specific embodiment of the present invention.

[0184] like Fig.11 As shown in the control method 150, the ventilation unit 1 is set to the fresh air introduction mode P1 for introducing fresh air, and the outdoor ambient humidity is detected according to the outdoor ambient humidity detection value H W On the basis of adjusting the fresh air introduction amount of the ventilation unit 1, the outdoor ambient temperature is further detected, and according to the outdoor temperature detection value T W The amount of fresh air introduced by the ventilation unit 1 , the temperature of the air output by the ventilation unit 1 , the temperature of the air output by the humidification unit 2 , or the humidification amount of the humidification unit 2 is adjusted.

[0185] Specifically, the control method 150 includes the following steps:

[0186] 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 .

[0187] Step S91, the detection unit 3 also detects the outdoor ambient temperature and obtains the outdoor humidity detection value T W .

[0188] Step S92: the control unit 4 converts the outdoor temperature detection value T detected by the detection unit 3 into W With temperature preset value T Y Make a comparison.

[0189] Step S93, the control unit 4 detects the outdoor temperature T W Adjust at least one of the amount of fresh air introduced by the ventilation unit 1, the air temperature output by the ventilation unit 1, the air temperature output by the humidification unit 2, and the humidification amount of the humidification unit 2. When adjusting the air temperature output by the ventilation unit 1 or the air temperature output by the humidification unit 2, it can be adjusted by a temperature adjustment device.

[0190] As the seasons change, the outdoor temperature changes greatly, and the temperature difference between morning and evening also varies. When the ventilation unit 1 introduces fresh air, the temperature of the outdoor air affects the comfort of the indoor air. Therefore, the outdoor temperature detection value T is detected. W , and according to the outdoor temperature detection value T W With temperature preset value T Y Adjust the indoor air comfort level based on the comparison results.

[0191] When the outdoor temperature detection value T W With temperature preset value T Y When the outdoor temperature is close to the target temperature, the fresh air intake of the ventilation unit 1 can be adjusted according to the target temperature, and more fresh air can be introduced. W With temperature preset value T Y When the difference is large, less fresh air can be introduced to reduce the impact on indoor air temperature.

[0192] It can also be detected according to the outdoor temperature value T W With temperature preset value T Y The comparison result is used to adjust the air temperature output by the ventilation unit 1. For example, when the outdoor temperature detection value T W Greater than or equal to the temperature preset value T Y When the ventilation unit 1 introduces fresh air, the temperature of the air blown out can be reduced. W Less than the preset temperature value T Y When the temperature of the air blown out by the ventilation unit 1 is increased, the blown air has a suitable temperature.

[0193] In addition, the outdoor temperature detection value T W With temperature preset value T Y The comparison result adjusts the air temperature output by the humidification unit 2. For example, when the outdoor temperature detection value T W Greater than or equal to the temperature preset value T Y When the ventilation unit 1 introduces fresh air and transmits it to the humidification unit 2, the high temperature humid air output by the humidification unit 2 is cooled down, so that the output air has a suitable temperature. W Less than the preset temperature value T Y When the temperature of the air output by the humidification unit 2 is increased, the output air has a suitable temperature.

[0194] It can also be detected according to the outdoor temperature value T W With temperature preset value T Y The comparison result adjusts the humidification amount of the humidification unit 2. For example, when the outdoor temperature detection value T W Greater than or equal to the temperature preset value T YWhen the air temperature is relatively high, the air with a higher temperature is prone to humidity loss, and the air is relatively dry. At this time, the humidification capacity of the humidification unit 2 can be increased. W Less than the preset temperature value T Y When the air temperature is relatively low, the air with a low temperature is not easy to cause humidity loss, and the air is relatively humid. At this time, the humidification amount of the humidification unit 2 can be reduced.

[0195] Fig.12 FIG. 1 is a flow chart of an air handling system control method 160 according to another specific embodiment of the present invention.

[0196] like Fig.12 As shown, when detecting the outdoor humidity, according to the outdoor humidity detection value H W On the basis of adjusting the fresh air introduction amount of the ventilation unit 1, the indoor temperature is further detected, and the control unit 4 is based on the indoor temperature detection value T N , adjust the air temperature at the output of the humidification unit 2.

[0197] The temperature of the indoor air affects the comfort of the indoor air. The indoor temperature detection value T can be detected N , and according to the indoor temperature detection value T N With temperature preset value T Y Adjust the indoor air comfort level based on the comparison results.

[0198] Specifically, the control method 160 includes the following steps:

[0199] Step 101, the detection unit 3 detects the indoor temperature detection value T N .

[0200] Step 102: The indoor temperature detection value T N With temperature preset value T Y When the indoor temperature detection value T N Greater than or equal to the temperature preset value T Y When the indoor temperature detection value T N Less than the preset temperature value T Y , execute step S104.

[0201] In step S103, when the indoor temperature detection value T N Greater than or equal to the temperature preset value T Y When the indoor air temperature is relatively high, the higher air temperature is prone to cause humidity loss, resulting in air dryness. At this time, the humidification capacity of the humidification unit 2 can be increased.

[0202] In step S104, when the indoor temperature detection value T N Less than the preset temperature value T YWhen the indoor air temperature is relatively low, the lower air temperature is not easy to cause humidity loss, and the air is relatively humid. At this time, the humidification amount of the humidification unit 2 can be reduced.

[0203] In addition to the above embodiments, as another embodiment, when the ventilation unit 1 is set to the strong air supply mode P4, the control unit 4 adjusts the indoor humidity detection value H N The humidification amount of the humidification unit 2 is adjusted.

[0204] When the ventilation unit 1 executes the strong air supply mode P4, the ventilation unit 1 operates at high power, the amount of fresh air introduced is large, and the indoor humidity is greatly affected by the fresh air. At this time, the detection unit 3 detects the indoor humidity detection value H N And with the humidity preset value H Y The comparison is performed, and the humidification amount of the humidifying unit 2 is adjusted according to the comparison result.

[0205] When the indoor humidity value is low, the humidifying unit 2 executes the second humidifying mode F2, so that the water level of the humidifying component 21 is in the first height interval, and the humidifying unit 2 operates at a high water level to increase the humidification amount and ensure the indoor humidity comfort.

[0206] When the indoor humidity value is high, the humidifying unit 2 executes the first humidifying mode F1, so that the water level of the humidifying component 21 is in the second height interval. The humidifying unit 2 operates at a medium water level to reduce the humidification amount, thereby reducing water replenishment while ensuring the indoor humidity comfort.

[0207] As mentioned above, in the strong air supply mode P4, according to the indoor humidity detection value H N The humidification amount of the humidification unit 2 is adjusted to ensure the humidification effect, ensure the indoor humidity comfort level and save water.

[0208] The air treatment system 100 and control methods 110, 120, 130, 140, 150, 160 of the present invention adjust the humidification mode and the ventilation mode according to the real-time air environment, thereby achieving joint regulation between humidification and ventilation with high control accuracy.
