Description

Technical Field

[0001] This application relates to the field of air quality control technology, and in particular to a fresh air humidification and control device and its control method. Background Technology

[0002] Fresh air humidifiers are effective air handling devices that circulate indoor and outdoor air. They draw in indoor and outdoor air, filter, heat, and humidify it, and then exhaust it back into the room, maintaining a consistent temperature, humidity, and freshness to ensure user comfort. However, most existing fresh air humidifiers use a bottom-intake, top-exhaust structure. This means that air entering the device must pass through the internal air handling structure, including the humidification components, before being exhausted back into the room. In other words, the exhaust air from existing fresh air humidifiers cannot return to the room with only partially humidified air. This results in inflexible humidification adjustments and an inability to meet the comfort requirements of various groups. Summary of the Invention

[0003] This application provides a fresh air humidification and regulation device and its control method, aiming to improve the problem that the air outlet of the existing fresh air humidification and regulation device cannot return to the room when the gas is not completely humidified, resulting in inflexible humidification adjustment and inability to meet the comfort requirements of various groups of people.

[0004] Therefore, a first aspect of this application provides a fresh air humidification and conditioning device, including a device housing, an air pretreatment component, and a humidification treatment component, wherein...

[0005] The device housing has an internal air duct cavity and an air outlet, an air inlet / outlet, a return air inlet, and a fresh air inlet that are respectively connected to the air duct cavity.

[0006] The air pretreatment component is installed in the third chamber, and the indoor air flowing in through the return air inlet and / or the outdoor air flowing in through the fresh air inlet first flows through the air pretreatment component before flowing into the second chamber.

[0007] The humidification treatment component is installed in the first chamber and extends partially into the second chamber, such that the gas flowing into the second chamber either flows out through the air inlet and outlet, or merges with the indoor gas flowing in through the air inlet and outlet, flows through the humidification treatment component first, and then flows into the first chamber and flows out through the air outlet.

[0008] Optionally, in some embodiments of this application, the fresh air inlet is located on the outdoor-facing surface of the equipment housing, and the return air inlet is located on the outdoor-facing surface of the equipment housing.

[0009] Optionally, in some embodiments of this application, a damper is further included, the damper being installed on the side of the third chamber away from the second chamber, so as to divide the space of the third chamber away from the second chamber into a first air duct connecting the return air inlet and the air pretreatment component and a second air duct connecting the fresh air inlet and the air pretreatment component.

[0010] Optionally, in some embodiments of this application, the air pretreatment component includes a first fan for accelerating the inflow of indoor air through the return air vent and / or accelerating the inflow of outdoor air through the fresh air vent.

[0013] Optionally, in some embodiments of this application, the humidification assembly includes a humidification water tank, a humidification filter, and a second fan, wherein,

[0014] The humidifying water tank is installed in the second chamber and is located near the side wall of the second chamber opposite the air inlet / outlet, so as to provide moisture to the humidifying filter by storing water;

[0015] The humidifying filter is installed on the humidifying water tank and extends partially into the first chamber to increase the contact area between water and air through capillary force, thereby enhancing the evaporation of water in the air and humidifying the passing gas.

[0016] The second fan is installed in the first chamber and located between the air outlet and the humidifying filter to accelerate the gas through the humidifying filter and out through the air outlet.

[0017] Optionally, in some embodiments of this application, a temperature and humidity sensor and a carbon dioxide sensor are also included, the temperature and humidity sensor and the carbon dioxide sensor being respectively disposed on the other surfaces of the device housing except for the surface facing the outside.

[0018] Furthermore, a second aspect of this application provides a control method for a fresh air humidification and conditioning device, applied to the aforementioned fresh air humidification and conditioning device, the control method comprising the following steps:

[0019] Obtain the current operating mode of the device and determine whether the device is currently in manual control mode or automatic control mode;

[0020] If the device is currently in manual control mode, it automatically acquires the first target air parameter currently input by the user and the ambient air parameter of the environment in which the device is currently located, and performs corresponding function adjustments based on the difference between the ambient air parameter and the first target air parameter, so that the ambient air parameter is consistent with the first target air parameter.

[0021] If the device is currently in automatic control mode, it automatically acquires the second target air parameter preset by the system and the ambient air parameter of the environment in which the device is currently located, and performs corresponding function adjustments according to the difference between the ambient air parameter and the second target air parameter, so that the ambient air parameter and the second target air parameter are consistent.

[0022] Optionally, in some embodiments of this application, the first target air parameter includes a first target temperature value, a first target relative humidity value, and a first target carbon dioxide concentration value; the ambient air parameter includes an ambient temperature value, an ambient relative humidity value, and an ambient carbon dioxide concentration value; and the second target air parameter includes a second target temperature value, a second target relative humidity value, and a second target carbon dioxide concentration value.

[0023] The step of performing corresponding functional adjustments based on the difference between the ambient air parameters and the first target air parameters to ensure that the ambient air parameters are consistent with the first target air parameters includes: if the ambient temperature value differs from the first target temperature value, then based on the difference between the ambient temperature value and the first target temperature value, controlling the air pretreatment component to perform heating and controlling the airflow ratio between the air inlet / outlet and the air outlet to ensure that the ambient temperature value is consistent with the first target temperature value; if the ambient relative humidity value differs from the first target relative humidity value, then based on the difference between the ambient relative humidity value and the first target relative humidity value, controlling the humidification component to perform humidification and controlling the airflow ratio between the air inlet / outlet and the air outlet to ensure that the ambient relative humidity value is consistent with the first target relative humidity value; if the ambient carbon dioxide concentration value differs from the first target carbon dioxide concentration value, then based on the difference between the ambient carbon dioxide concentration value and the first target carbon dioxide concentration value, controlling the airflow ratio between the fresh air inlet and the return air inlet to ensure that the ambient carbon dioxide concentration value is consistent with the first target carbon dioxide concentration value.

[0024] The step of performing corresponding functional adjustments based on the difference between the ambient air parameters and the second target air parameters to ensure consistency between the ambient air parameters and the second target air parameters includes: if there is a difference between the ambient temperature value and the second target temperature value, then controlling the air pretreatment component to perform heating and controlling the airflow ratio between the air inlet / outlet and the air outlet based on the difference between the ambient temperature value and the second target temperature value, so that the ambient temperature value is consistent with the second target temperature value; if there is a difference between the ambient relative humidity value and the second target relative humidity value, then controlling the humidification component to perform humidification and controlling the airflow ratio between the air inlet / outlet and the air outlet based on the difference between the ambient relative humidity value and the second target relative humidity value, so that the ambient relative humidity value is consistent with the second target relative humidity value; if there is a difference between the ambient carbon dioxide concentration value and the second target carbon dioxide concentration value, then controlling the airflow ratio between the fresh air inlet and the return air inlet based on the difference between the ambient carbon dioxide concentration value and the second target carbon dioxide concentration value, so that the ambient carbon dioxide concentration value is consistent with the second target carbon dioxide concentration value.

[0025] The fresh air humidification and conditioning equipment and its control method provided in this application include a housing, an air pretreatment component, and a humidification component. The housing contains a duct cavity and has an air outlet, an air inlet / outlet, a return air inlet, and a fresh air inlet connected to the duct cavity. The duct cavity includes a first chamber, a second chamber, and a third chamber connected sequentially from top to bottom. The air outlet is located on the side of the first chamber furthest from the second chamber, the air inlet / outlet is located in the second chamber, and the return air inlet and fresh air inlet are located on the side of the third chamber furthest from the second chamber. The air pretreatment component is installed in the third chamber, ensuring that indoor air flowing in through the return air inlet and / or outdoor air flowing in through the fresh air inlet first passes through the air pretreatment component before flowing into the second chamber. The humidification unit is installed in the first chamber and partially extends into the second chamber. This allows the air flowing into the second chamber to either exit through the inlet and outlet, or to merge with indoor air flowing in through the inlet and outlet, first passing through the humidification unit before flowing into the first chamber and exiting through the outlet. Thus, through this structural arrangement, the fresh air humidification and regulation device of this application, in addition to having an outlet at the top, also has an inlet and outlet in the middle. This inlet and outlet also functions as a return air inlet and outlet, allowing the return air to return to the room without being entirely humidified by the humidification unit. This enables flexible adjustment of the humidification amount, providing multiple humidification and fresh air regulation modes, better meeting the comfort requirements of various groups, and thus improving the comfort performance of the fresh air humidification device. Therefore, this technical solution effectively improves the problem of existing fresh air humidification and regulation devices where the outlet air cannot return to the room without being entirely humidified, resulting in inflexible humidification adjustment and an inability to meet the comfort requirements of various groups.

[0037] In one embodiment, such as Figure 1As shown, this application embodiment provides a fresh air humidification and conditioning device 100. The fresh air humidification and conditioning device 100 may specifically include a device housing 110, an air pretreatment component 120, and a humidification treatment component 130. The device housing 110 has a built-in air duct cavity 111 and an air outlet 112, an air inlet / outlet 113, a return air inlet 114, and a fresh air inlet 115 that are respectively connected to the air duct cavity 111. The air duct cavity 111 includes a first chamber, a second chamber, and a third chamber that are sequentially connected from top to bottom. The air outlet 112 is located on the side of the first chamber away from the second chamber. The air inlet / outlet 113 is located on the side of the second chamber. The return air inlet 114 and the fresh air inlet 115 are respectively located on the side of the third chamber away from the second chamber. An air pretreatment unit 120 is installed in the third chamber, such that indoor air flowing in through the return air inlet 114 and / or outdoor air flowing in through the fresh air inlet 115 first flows through the air pretreatment unit 120 before flowing into the second chamber. A humidification unit 130 is installed in the first chamber and partially extends into the second chamber, such that air flowing into the second chamber either flows out through the air inlet / outlet 113 or merges with indoor air flowing in through the air inlet / outlet 113, first flows through the humidification unit 130 before flowing into the first chamber and then out through the air outlet 112.

[0038] It is understood that the fresh air humidification and conditioning device 100 mentioned in this application embodiment is mainly used indoors to effectively improve indoor air quality by adjusting parameters such as relative humidity, temperature, and carbon dioxide concentration in the indoor air. The aforementioned fresh air inlet 115 is mainly used to connect to the outside to access outdoor air; that is, the fresh air mentioned in this application can specifically refer to air introduced from the outside into the room. The aforementioned return air inlet 114 is mainly used to connect to the inside to access indoor air; that is, the return air mentioned in this application can specifically refer to air introduced from the indoor air duct for further processing. The aforementioned duct cavity 111 includes a first chamber, a second chamber, and a third chamber arranged sequentially from top to bottom. Specifically, this means that the duct cavity 111 can be divided into three chambers by baffles, or it can be virtually divided into three chambers based on spatial differences. That is, the three chambers are essentially still a single duct cavity 111, but different chamber names are used to distinguish different locations of the duct cavity 111 to indicate the installation positions of different openings and components. Based on this, the aforementioned air outlet 112, air inlet / outlet 113, return air inlet 114, and fresh air inlet 115 can be installed as follows: air outlet 112 is located at the top of the equipment housing 110; air inlet / outlet 113 is located at the middle of the equipment housing 110; and return air inlet 114 and fresh air inlet 115 are located at the bottom of the equipment housing 110. The aforementioned air pretreatment component 120 and humidification component 130 can be installed as follows: air pretreatment component 120 is located near the middle of the bottom of the equipment housing 110; and humidification component 130 is located near the middle of the top of the equipment housing 110, extending partially to the middle of the equipment housing 110.

[0039] Furthermore, in order for the gas flowing into the second chamber to first flow through the humidification unit 130 after merging with the indoor gas flowing in through the air inlet / outlet 113, and then flow into the first chamber, the humidification unit 130 must be installed such that the entire flow path from the second chamber to the first chamber is occupied by the humidification unit 130. Similarly, in order for the gas flowing into the second chamber (specifically, the gas flowing into the second chamber from the first chamber, which can be outdoor gas and / or outdoor air) to partially bypass the humidification unit 130 and flow directly out through the air inlet / outlet 113, the humidification unit 130 must be installed such that at least part of the flow path from the first chamber to the second chamber is not occupied by the humidification unit 130.

[0040] In this way, through the above structural arrangement, the fresh air humidification and conditioning device 100 of this application embodiment has not only an air outlet 112 set at the top, but also an air inlet and outlet 113 set in the middle. The air inlet and outlet 113 also has the function of returning air inlet and outlet, so that the returning air can return to the room without being humidified by the humidification treatment component 130. In this way, the humidification amount can be flexibly adjusted to obtain a variety of humidification and fresh air conditioning modes, which can better meet the comfort requirements of a variety of people, thereby improving the comfort performance of the fresh air humidification device from the perspective of selection.

[0041] In some examples, such as Figure 1 As shown, the fresh air inlet 115 is located on the outdoor-facing surface of the equipment housing 110, while the return air inlet 114 is located on the outdoor-facing surface of the equipment housing 110. Thus, this structural arrangement allows the fresh air inlet 115 and the return air inlet 114 to be located on different side surfaces of the equipment housing 110, although both are located at the bottom of the housing. This allows the fresh air inlet 115 to better face the outdoor environment to receive outdoor air, and the return air inlet 114 to better face the indoor environment to receive indoor air.

[0042] In some examples, such as Figure 1 As shown, the fresh air humidification and conditioning device 100 also includes an air valve 140. The air valve 140 is installed on the side of the third chamber away from the second chamber, so as to divide the space of the third chamber away from the second chamber into a first air duct connecting the return air inlet 114 and the air pretreatment component 120, and a second air duct connecting the fresh air inlet 115 and the air pretreatment component 120. In this way, with the above structural arrangement, in conjunction with the fresh air inlet 115 and the return air inlet 114 located on different side surfaces of the device housing 110, the air valve 140 can control the proportion of fresh air and return air entering the first chamber by controlling the air inlet area of ​​the first air duct and the second air duct. Specifically, it can be set so that when the air valve 140 is adjusted, the larger the opening, the larger the proportion of fresh air and the smaller the proportion of return air.

[0043] In some examples, such as Figure 1 As shown, the air pretreatment component 120 includes a first fan 121, which is used to accelerate the inflow of indoor air through the return air vent 114 and / or accelerate the inflow of outdoor air through the fresh air vent 115. Thus, the above-described structure allows for accelerated inflow of indoor air through the return air vent 114 and / or accelerated inflow of outdoor air through the fresh air vent 115.

[0044] It is understood that the first fan 121 can be, but is not limited to, an axial flow fan, a cross-flow fan, and a centrifugal fan. The first fan 121 is preferably located close to the outlet of the first and second air ducts in the example above. Thus, the speed of gas flow within the first and second air ducts can be controlled by controlling the rotational speed of the first fan 121.

[0045] In some examples, such as Figure 1 As shown, the air pretreatment assembly 120 also includes an air filtration structure 122 and an air heating structure 123. The air filtration structure 122 is used to filter the passing gas, and the air heating structure 123 is used to heat the passing gas. Thus, through the above structural arrangement, the gas from the first chamber undergoes air filtration and air heating treatment before flowing into the second chamber, ensuring that the exiting air is clean and reaches a preset temperature value.

[0046] Understandably, the air filtration structure 122 may specifically employ a dense filter to filter out fine particles in the air, ensuring that the exiting air is clean. The air heating structure 123 may employ a heating wire mesh to heat the air passing through the mesh, ensuring that the exiting air reaches a preset temperature value. Generally, the gas in the first chamber (including indoor gas flowing in through the return air vent 114 and / or outdoor gas flowing in through the fresh air vent 115) should first flow through the air filtration structure 122 and then through the air heating structure 123 to prevent fine particles in the air from affecting the heating effect of the air heating structure 123. In addition, the air pretreatment assembly 120 may also include other air treatment structures to perform other air treatments besides air filtration and air heating.

[0047] In some examples, such as Figure 1 As shown, the air inlet 113 and air outlet 112 are both located on the surface of the equipment housing 110 away from the outside. In this way, the above-mentioned structural arrangement ensures that the air inlet 113 and air outlet 112 can be better oriented towards the outside, so as to introduce indoor air through the air inlet 113 or exhaust treated gas into the room through the air inlet 113 and air outlet 112.

[0048] In some examples, such as Figure 1As shown, the humidification treatment assembly 130 includes a humidifying water tank 131, a humidifying filter 132, and a second fan 133. The humidifying water tank 131 is installed in the second chamber, near the side wall of the second chamber opposite the air inlet / outlet 113, to supply moisture to the humidifying filter 132 by storing water. The humidifying filter 132 is installed on the humidifying water tank 131 and partially extends into the first chamber to increase the contact area between water and air through capillary action, thereby enhancing the evaporation of water in the air and humidifying the passing air. The second fan 133 is installed in the first chamber, located between the air outlet 112 and the humidifying filter 132, to accelerate the passage of air through the humidifying filter 132 and its exit through the air outlet 112. Thus, through the structural arrangement of the humidifying filter 132 and the humidifying water tank 131, the gas flowing into the second chamber (specifically, the gas flowing into the second chamber from the first chamber, which can be outdoor gas and / or outdoor air) merges with the indoor gas flowing in through the air inlet / outlet 113. When the gas flows through the humidifying filter 132, the humidifying filter 132 increases the humidity of these gases through evaporation. At the same time, through the structural arrangement of the second fan 133, these gases can pass through the humidifying filter 132 more quickly and flow out through the air outlet 112.

[0049] Understandably, in order for the gas flowing into the second chamber to first pass through the humidifying filter 132 after merging with the indoor gas flowing in through the air inlet / outlet 113, and then flow into the first chamber, the humidifying filter 132 must be installed such that the entire flow path from the second chamber to the first chamber is occupied by the humidifying filter 132. Similarly, in order for the gas flowing into the second chamber (specifically, the gas flowing into the second chamber from the first chamber, which can be outdoor gas and / or outdoor air) to partially bypass the humidifying filter 132 and flow directly out through the air inlet / outlet 113, the humidifying filter 132 must be installed such that at least part of the flow path from the first chamber to the second chamber is not occupied by the humidifying filter 132. The second fan 133 can be, but is not limited to, an axial flow fan and a cross-flow fan. The second fan 133 is preferably located between the air outlet 112 and the humidifying filter 132, and is positioned close to the humidifying filter 132. In this way, the speed of gas flow through humidifying filter 132 can be controlled by controlling the rotation speed of the second fan 133.

[0050] In some examples, such as Figure 1 As shown, the fresh air humidification and conditioning device 1 also includes a temperature and humidity sensor (not shown) and a carbon dioxide sensor (not shown), which are respectively installed on the surfaces of the device housing 110 other than the surface facing the outside. Thus, with the above structural arrangement, the air parameters of the indoor environment where the fresh air humidification and conditioning device 1 is located can be monitored in real time, such as ambient temperature, relative humidity, and carbon dioxide concentration.

[0051] It is understandable that, since the fresh air inlet 115 and the return air inlet 114 are located at... Figure 1 On the left and right sides of the device housing 110 shown, i.e. Figure 1 The right-hand surface of the device housing 110 is the side facing outdoors; therefore, the temperature and humidity sensor and the carbon dioxide sensor can be located respectively in... Figure 1 The front and rear surfaces of the device housing 110 shown are located near Figure 1 The position of the device housing 110 on the left side surface is shown, which allows for better detection of indoor air parameters. Since the relative humidity value needs to be obtained by simultaneously acquiring both indoor and outdoor humidity values, the controller of the fresh air humidification and conditioning device 1 also needs to be connected to the outside environment to obtain the outdoor humidity value.

[0052] In one embodiment, such as Figure 2 As shown in the embodiments of this application, a control method for a fresh air humidification and conditioning device is also provided. This control method is applied to the fresh air humidification and conditioning device 1 in the above embodiments, and the control method may specifically include the following steps:

[0053] Step S110: Obtain the current operating mode of the device and determine whether the device is currently in manual control mode or automatic control mode.

[0054] It is understandable that, such as Figure 1 As shown, the fresh air humidification and conditioning device 1 in the above embodiment has two working modes: manual control mode and automatic control mode, allowing users to freely switch between them to meet the needs of more usage scenarios. Therefore, when the fresh air humidification and conditioning device 1 is working, it needs to first obtain the current operating mode of the device to determine whether the device is currently in manual control mode or automatic control mode, so that the device can perform the corresponding air humidification and conditioning treatment according to the corresponding working mode.

[0055] Step S120: If the device is currently in manual control mode, it automatically obtains the first target air parameter currently input by the user and the ambient air parameter of the environment in which the device is currently located, and performs corresponding function adjustments according to the difference between the ambient air parameter and the first target air parameter, so that the ambient air parameter is consistent with the first target air parameter.

[0056] Understandably, when the above steps determine that the device is currently in manual control mode, it can automatically acquire the user's currently input first target air parameter and the ambient air parameter of the device's current environment. Based on the difference between the ambient air parameter and the first target air parameter, it will perform corresponding functional adjustments to ensure that the ambient air parameter is consistent with the first target air parameter. Generally, when the user selects manual control mode without inputting a new first target air parameter, the system will default to the user's last previously input target air parameter and control the device to perform corresponding functional adjustments to ensure that the ambient air parameter is consistent with the first target air parameter. However, during device operation, when the user inputs a new target air parameter, the system will adjust the new target air parameter to match the first target air parameter and control the device to perform corresponding functional adjustments to ensure that the ambient air parameter is consistent with the first target air parameter.

[0057] Step S130: If the device is currently in automatic control mode, it automatically acquires the second target air parameter preset by the system and the ambient air parameter of the environment in which the device is currently located, and performs corresponding function adjustments according to the difference between the ambient air parameter and the second target air parameter, so that the ambient air parameter and the second target air parameter are consistent.

[0058] Understandably, when the above steps determine that the device is currently in automatic control mode, it can automatically acquire the system's preset target air parameters and the ambient air parameters of the current environment. Based on the difference between the ambient air parameters and the target air parameters, it will perform corresponding functional adjustments to ensure that the ambient air parameters are consistent with the target air parameters. Generally, the system's preset target air parameters can be referenced in the national standard GB / T18883-2022 "Indoor Air Quality Standard" and are preset in the system. Different parameters are typically set for different seasons. Therefore, when the device is in automatic control mode, the system will first select the appropriate system setting based on the current season, i.e., the system's preset target air parameters. For example, the national standard GB / T18883-2022 "Indoor Air Quality Standard" stipulates that the indoor air quality requirements in winter are that the temperature should be between 16℃ and 24℃, and the relative humidity should be between 30% and 60%, based on the average value. Therefore, the specific system settings for winter can be as follows: the target temperature value should be 20℃, the relative humidity value should be 45%, and the target carbon dioxide concentration value should be below 1000ppm (0.1% a).

[0059] In this way, through the above methods and steps, the air parameters of the indoor environment where the fresh air humidification and conditioning equipment 1 is located can be consistent with the corresponding target air parameters, regardless of the operating mode, so as to meet the comfort requirements of various groups of people and thus improve the comfort performance of the fresh air humidification and conditioning equipment.

[0060] In some examples, the fresh air humidification and conditioning device 1 in this application embodiment is mainly used to adjust the temperature, relative humidity, and carbon dioxide concentration in indoor air. Therefore, the aforementioned first target air parameter may specifically include a first target temperature, a first target relative humidity, and a first target carbon dioxide concentration. Similarly, ambient air parameters include ambient temperature, ambient relative humidity, and ambient carbon dioxide concentration, and the second target air parameter includes a second target temperature, a second target relative humidity, and a second target carbon dioxide concentration. At this time, as... Figure 3 As shown, the process of "adjusting the ambient air parameters according to the difference between the ambient air parameters and the first target air parameters, so that the ambient air parameters are consistent with the first target air parameters" in the above method steps is as follows:

[0061] Step S121: If there is a difference between the ambient temperature value and the first target temperature value, then based on the difference between the ambient temperature value and the first target temperature value, control the air pretreatment component to perform heating and control the air volume ratio between the air inlet and outlet to ensure that the ambient temperature value is consistent with the first target temperature value.

[0062] Understandably, the main purpose of this method is to ensure that the ambient temperature remains consistent with the first target temperature. This is generally achieved by controlling the heating operation of the air pretreatment component 120 and controlling the airflow ratio between the inlet / outlet 113 and the outlet 112 based on the difference between the ambient temperature and the first target temperature. Specifically, controlling the airflow ratio between the inlet / outlet 113 and the outlet 112 can be achieved by controlling the rotational speed of the second fan 133. Taking a difference of α between the ambient temperature and the first target temperature as an example, and a threshold of 5℃, the specific method is as follows: when α ≥ 5℃, reduce the rotational speed of the second fan 133, making the inlet / outlet 113 the primary outlet; when α < 5℃, increase the rotational speed of the second fan 133, making the outlet 112 the outlet and the inlet / outlet 113 the inlet. In this way, by controlling the temperature using the above methods, energy conservation and environmental protection can be achieved while ensuring that the ambient temperature quickly reaches the first target temperature.

[0063] Step S122: If there is a difference between the ambient relative humidity value and the first target relative humidity value, then based on the difference between the ambient relative humidity value and the first target relative humidity value, control the humidification processing component to perform humidification work and control the air volume ratio between the air inlet and outlet to make the ambient relative humidity value consistent with the first target relative humidity value.

[0064] Understandably, the main purpose of this method is to ensure that the ambient relative humidity value is consistent with the first target relative humidity value. This is generally achieved by controlling the humidification unit 130 to perform humidification based on the difference between the ambient and target relative humidity values, and by controlling the airflow ratio between the inlet / outlet 113 and the outlet 112. Controlling the airflow ratio between the inlet / outlet 113 and the outlet 112 can be achieved by controlling the rotational speed of the second fan 133. Specifically, the rotational speed of the second fan 113 is adjusted according to the difference σ between the ambient and target relative humidity values. Through these methods, the ambient temperature value can be made consistent with the first target temperature value as quickly as possible while also considering energy conservation and environmental protection.

[0065] In addition, according to the law of conservation of mass, the humidification amount is calculated as follows (excluding unit conversion factors):

[0066]

[0067] Where: V, m, V o d o V i d i Total air volume, total air mass flow rate, fresh air volume, fresh air humidity, return air volume, and return air humidity; ρ a ρ l For air density and liquid water density; m wo m wi m js m ao m ai The values ​​are: fresh air moisture mass flow rate, return air moisture mass flow rate, humidification moisture mass flow rate, fresh air dry air mass flow rate, and return air dry air mass flow rate.

[0068] Step S123: If there is a difference between the ambient carbon dioxide concentration and the first target carbon dioxide concentration, the ratio of the intake air volume between the fresh air inlet and the return air inlet is controlled according to the difference between the ambient carbon dioxide concentration and the first target carbon dioxide concentration, so that the ambient carbon dioxide concentration and the first target carbon dioxide concentration are consistent.

[0069] Understandably, the main purpose of this method is to ensure that the carbon dioxide concentration value is consistent with the first target carbon dioxide concentration value. This is generally achieved by controlling the air intake ratio between the fresh air inlet 115 and the return air inlet 114 based on the difference between the ambient carbon dioxide concentration value and the first target carbon dioxide concentration value. Specifically, controlling the air intake ratio between the fresh air inlet 115 and the return air inlet 114 can be achieved by controlling the opening of the damper. The damper opening can be adjusted according to the difference between the ambient carbon dioxide concentration value and the first target carbon dioxide concentration value. If the difference is large, the damper opening can be increased to increase the proportion of fresh air. Thus, by controlling the air intake ratio through the above methods, the ambient carbon dioxide concentration value can be kept consistent with the first target carbon dioxide concentration value while simultaneously considering energy conservation and environmental protection.

[0070] Similarly, such as Figure 3 As shown, the process of "adjusting the ambient air parameters according to the difference between the ambient air parameters and the second target air parameters to keep them consistent" in the above method steps is as follows:

[0071] Step S131: If there is a difference between the ambient temperature value and the second target temperature value, then based on the difference between the ambient temperature value and the second target temperature value, control the air pretreatment component to perform heating and control the air volume ratio between the air inlet and outlet to ensure that the ambient temperature value and the second target temperature value are consistent.

[0072] It is understood that the specific steps of this method can be referred to in step S121 above, and will not be repeated here.

[0073] Step S132: If there is a difference between the ambient relative humidity value and the second target relative humidity value, then based on the difference between the ambient relative humidity value and the second target relative humidity value, control the humidification processing component to perform humidification work and control the air volume ratio between the air inlet and outlet to make the ambient relative humidity value consistent with the second target relative humidity value.

[0074] It is understood that the specific steps of this method can be referred to in step S122 above, and will not be repeated here.

[0075] Step S133: If there is a difference between the ambient carbon dioxide concentration and the second target carbon dioxide concentration, the ratio of the intake air volume between the fresh air inlet and the return air inlet is controlled according to the difference between the ambient carbon dioxide concentration and the second target carbon dioxide concentration, so that the ambient carbon dioxide concentration and the second target carbon dioxide concentration are consistent.

[0076] It is understood that the specific steps of this method can be referred to in step S123 above, and will not be repeated here.
