[0002] The fresh air humidification regulation device is an effective air treatment device that can circulate indoor and outdoor air. That is, by inhaling indoor and outdoor gases and filtering, heating, and humidifying these gases, and then discharging them back into the room, the indoor air can always maintain a certain temperature and humidity and freshness, ensuring the comfort of users. However, since most of the existing fresh air humidification regulation devices adopt a structure with bottom air intake and top air outlet, the air entering the device can only be discharged back into the room after flowing through the air treatment structure including the humidification treatment component inside. That is, the air outlet of the existing fresh air humidification regulation device cannot return to the room when the air is not all humidified, which will lead to inflexible adjustment of the humidification amount and cannot meet the comfort requirements of various people.

The fresh air humidification adjustment device includes a device housing, an air pretreatment component, and a humidification treatment component. Among them, the device housing is internally provided with an air duct cavity, and the surface is provided with an air outlet, an air inlet / outlet, a return air outlet, and a fresh air inlet that are respectively communicated with the air duct cavity.

[0037] In one embodiment, as Figure 1As shown in the figure, an embodiment of the present application provides a fresh air humidification and regulation device 100, which specifically includes a device housing 110, an air pretreatment component 120, and a humidification treatment component 130. Among them, the device housing 110 is internally provided with an air duct cavity 111, and the surface is provided with an air outlet 112, an air inlet / outlet 113, a return air outlet 114, and a fresh air inlet 115 that are respectively communicated with the air duct cavity 111. The air duct cavity 111 includes a first chamber, a second chamber, and a third chamber that are sequentially communicated from top to bottom. The air outlet 112 is arranged corresponding to the side of the first chamber away from the second chamber, the air inlet / outlet 113 is arranged corresponding to the second chamber, and the return air outlet 114 and the fresh air inlet 115 are respectively arranged corresponding to the side of the third chamber away from the second chamber. The air pretreatment component 120 is installed in the third chamber, so that the indoor gas flowing in through the return air outlet 114 and / or the outdoor gas flowing in through the fresh air inlet 115 first flows through the air pretreatment component 120 and then flows into the second chamber. The humidification treatment component 130 is installed in the first chamber and partially extends into the second chamber, so that the gas flowing into the second chamber, or flows out through the air inlet / outlet 113, or converges with the indoor gas flowing in through the air inlet / outlet 113 first flows through the humidification treatment component 130 and then flows into the first chamber and flows out through the air outlet 112.

[0038] It can be understood that the fresh air humidification adjustment device 100 mentioned in the embodiments of the present application is mainly applied indoors to effectively improve the indoor air quality by adjusting parameters such as relative humidity, temperature, and carbon dioxide concentration in the indoor air. The above-mentioned fresh air inlet 115 is mainly used to connect to the outside to introduce outdoor air, that is, the fresh air mentioned in the present application can specifically be the air introduced from the outside into the room. The above-mentioned return air inlet 114 is mainly used to connect to the room to introduce indoor air, that is, the return air mentioned in the present application can specifically be the air introduced from the indoor air into the air duct for reprocessing. The above-mentioned air duct cavity 111 including the first chamber, the second chamber, and the third chamber that are connected in sequence from top to bottom specifically means that the air duct cavity 111 can be divided by baffles to actually divide into three chambers, or it can be virtually divided into three chambers based on the difference in spatial positions. That is, the three chambers are essentially still an integral air duct cavity 111, but different positions of the air duct cavity 111 are distinguished by different chamber names to correspondingly explain the installation positions of different openings and different components. Based on this, the installation positions of the above-mentioned air outlet 112, the air inlet and outlet 113, the return air inlet 114, and the fresh air inlet 115 can specifically be that the air outlet 112 is set corresponding to the top of the device housing 110, the air inlet and outlet 113 is set corresponding to the middle of the device housing 110, and the return air inlet 114 and the fresh air inlet 115 are respectively set corresponding to the bottom of the device housing 110. The installation positions of the above-mentioned air pretreatment component 120 and the humidification treatment component 130 can specifically be that the air pretreatment component 120 is set at a position near the middle of the bottom of the device housing 110, and the humidification treatment component 130 is set at a position near the middle of the top of the device housing 110 and partially extends to the middle of the device housing 110.

[0039] In addition, in order to enable the gas flowing into the second chamber to flow through the humidification treatment component 130 first after converging with the indoor gas flowing in through the air inlet and outlet 113 and then flow into the first chamber, the installation of the humidification treatment component 130 needs to ensure that the flow path from the second chamber to the first chamber is completely occupied by the humidification treatment component 130. Similarly, in order to enable part of the gas flowing into the second chamber (specifically referring to the gas flowing into the second chamber through the first chamber, which can be outdoor gas and / or outdoor gas) to flow out directly through the air inlet and outlet 113 without flowing through the humidification treatment component 130, the installation of the humidification treatment component 130 needs to ensure that at least part of the flow path from the first chamber to the second chamber is not occupied by the humidification treatment component 130.

[0040] In this way, through the above structural arrangement, the fresh air humidification adjustment device 100 of the embodiment of the present application, in addition to having the air outlet 112 provided at the top, also has the air inlet / outlet 113 provided in the middle. This air inlet / outlet 113 simultaneously functions as the inlet and outlet for the return air, enabling the return air to return to the room without being fully humidified by the humidification treatment component 130. Thus, the humidification amount can be flexibly adjusted, and various humidification and fresh air adjustment modes can be obtained, better meeting the comfort requirements of various people, and thereby enhancing the comfort performance of the fresh air humidification device in terms of selection.

[0041] In some examples, as Figure 1 shown, the fresh air inlet 115 is opened on the outer surface of the device housing 110 facing the outdoor side, and the return air inlet 114 is opened on the outer surface of the device housing 110 away from the outdoor side. In this way, through the above structural arrangement, although the fresh air inlet 115 and the return air inlet 114 are both located at the bottom of the device housing 110, they are respectively located on different side surfaces of the device housing 110. As a result, the fresh air inlet 115 faces the outdoor better to introduce outdoor air, and the return air inlet 114 faces the indoor better to introduce indoor air.

[0042] In some examples, as Figure 1 shown, the fresh air humidification adjustment device 100 further includes a damper 140. The damper 140 is installed on the side of the third chamber away from the second chamber to divide the space on the side 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, through the above structural arrangement, in cooperation with the fresh air inlet 115 and the return air inlet 114 located on different side surfaces of the device housing 110, the damper 140 can control the proportion of fresh air and return air entering the first chamber by controlling the inlet area of the first air duct and the second air duct. Specifically, it can be set that when the damper 140 is adjusted, the larger the opening degree, the greater the proportion of fresh air and the smaller the proportion of return air.

[0043] In some examples, as Figure 1 shown, the air pretreatment component 120 includes a first fan 121. The first fan 121 is used to accelerate the inflow of indoor gas through the return air inlet 114 and / or accelerate the inflow of outdoor gas through the fresh air inlet 115. In this way, through the above structural arrangement, the indoor gas can be accelerated to flow in through the return air inlet 114 and / or the outdoor gas can be accelerated to flow in through the fresh air inlet 115.

[0044] It can be understood that the first fan 121 may specifically be, but is not limited to, an axial flow fan, a cross flow fan, and a centrifugal fan. The first fan 121 is preferably arranged close to the outlets of the first air duct and the second air duct in the above examples. In this way, the speed of the gas flow in the first air duct and the second air duct can be controlled by controlling the rotation speed of the first fan 121.

[0045] In some examples, such as Figure 1 As shown, the air pretreatment assembly 120 further includes an air filtration structure 122 and an air heating structure 123. The air filtration structure 122 is used to perform air filtration treatment on the passing gas, and the air heating structure 123 is used to perform air heating treatment on the passing gas. In this way, through the above structural arrangement, the gas in the first chamber can pass through air filtration and air heating treatments in sequence before flowing into the second chamber, so as to ensure that the outgoing air is clean and reaches a preset temperature value.

[0046] It can be understood that the air filtration structure 122 may specifically adopt a dense filter screen to filter out the fine particles existing in the air, so as to ensure that the outgoing air is clean. The air heating structure 123 may adopt a heating wire mesh to heat the air passing through the heating wire mesh, so as to ensure that the outgoing air reaches a preset temperature value. Generally speaking, the gas in the first chamber (including the indoor gas flowing in through the return air outlet 114 and / or the outdoor gas flowing in through the fresh air inlet 115) should first flow through the air filtration structure 122 and then through the air heating structure 123 to prevent the fine particles in the air from affecting the heating effect of the air heating structure 123. In addition, the air pretreatment assembly 120 may further include other air treatment structures to perform other air treatments on the air besides air filtration and air heating.

[0047] In some examples, such as Figure 1 As shown, both the air inlet / outlet 113 and the air outlet 112 are opened on the surface of the equipment housing 110 away from the outside. In this way, through the above structural arrangement, it can be ensured that both the air inlet / outlet 113 and the air outlet 112 can better face the outside, so as to access indoor air through the air inlet / outlet 113 or discharge the treated gas into the room through the air inlet / outlet 113 and the air outlet 112.

[0048] In some examples, such as Figure 1As shown in the figure, the humidification processing component 130 includes a humidification water tank 131, a humidification filter screen 132, and a second blower 133. Among them, the humidification water tank 131 is installed in the second chamber and is disposed close to one side wall of the second chamber facing the air inlet and outlet 113, so as to provide moisture to the humidification filter screen 132 by storing water. The humidification filter screen 132 is installed on the humidification water tank 131 and partially extends into the first chamber, so as to expand the contact area between water and air through capillary force, enhance the evaporation amount of water in the air, and perform air humidification processing on the passing gas. The second blower 133 is installed in the first chamber and is located between the air outlet 112 and the humidification filter screen 132, so as to accelerate the gas to pass through the humidification filter screen 132 and flow out through the air outlet 112. In this way, through the structural settings of the above-mentioned humidification filter screen 132 and the humidification water tank 131, when the gas flowing into the second chamber (specifically referring to the gas flowing into the second chamber through the first chamber, which can be outdoor gas and / or outdoor gas) converges with the indoor gas flowing in through the air inlet and outlet 113 and flows through the humidification filter screen 132, the humidification filter screen 132 can increase the humidity of these gases in the form of evaporation. At the same time, through the structural setting of the second blower 133, the above-mentioned gases can be accelerated to pass through the humidification filter screen 132 and flow out through the air outlet 112.

[0049] It can be understood that in order to enable the gas flowing into the second chamber to flow through the humidification filter screen 132 first and then flow into the first chamber after converging with the indoor gas flowing in through the air inlet and outlet 113, the installation of the humidification filter screen 132 needs to make the flow path from the second chamber to the first chamber completely occupied by the humidification filter screen 132. Similarly, in order to enable part of the gas flowing into the second chamber (specifically referring to the gas flowing into the second chamber through the first chamber, which can be outdoor gas and / or outdoor gas) to flow directly out through the air inlet and outlet 113 without flowing through the humidification filter screen 132, the installation of the humidification filter screen 132 needs to make at least part of the flow path from the first chamber to the second chamber not occupied by the humidification filter screen 132. The second blower 133 can specifically be, but is not limited to, an axial flow blower and a cross flow blower. The second blower 133 is preferably located between the air outlet 112 and the humidification filter screen 132 and is disposed close to the humidification filter screen 132. In this way, the flow rate of the gas passing through the humidification filter screen 132 can be controlled by controlling the rotation speed of the second blower 133.

[0050] In some examples, as Figure 1 shown, the fresh air humidification and regulation device 1 further includes a temperature and humidity sensor (not shown) and a carbon dioxide sensor (not shown). The temperature and humidity sensor and the carbon dioxide sensor are respectively disposed on other surfaces of the device housing 110 except for the surface facing the outside. In this way, through the above structural settings, the air parameters of the indoor environment where the fresh air humidification and regulation device 1 is located, such as the ambient temperature value, the ambient relative humidity value, and the ambient carbon dioxide concentration value, can be monitored in real time.

[0051] It can be understood that, since the fresh air inlet 115 and the return air inlet 114 are respectively located on the left and right side surfaces of the equipment housing 110 shown in Figure 1 i.e., the right side surface in Figure 1 is the side surface of the equipment housing 110 facing the outside. Therefore, the temperature and humidity sensor and the carbon dioxide sensor can specifically be located on the front and rear side surfaces of the equipment housing 110 shown in Figure 1 and are located at positions close to the left side surface of the equipment housing 110 shown in Figure 1 In this way, the corresponding detection of the air parameters of the indoor environment can be better realized. Since the environmental relative humidity value needs to obtain the indoor environment humidity value and the outdoor environment humidity value simultaneously, the controller of the fresh air humidification and regulation device 1 also needs to be communicatively connected to the outside to obtain the outdoor environment humidity value.

[0052] In one embodiment, as shown in Figure 2 the embodiment of the present application also provides a control method for a fresh air humidification and regulation device. This control method is applied to the fresh air humidification and regulation device 1 in the above embodiment. Specifically, this control method may include the following steps:

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

[0054] It can be understood that, as shown in Figure 1 the fresh air humidification and regulation device 1 in the above embodiment has two working modes, namely the manual control mode and the automatic control mode, for the user to freely switch and select to meet the user's more usage scenario requirements. Therefore, when the fresh air humidification and regulation device 1 works, it is necessary to first obtain the current operating mode of the device to determine whether the device is currently in the manual control mode or the automatic control mode, so as to facilitate the device to perform corresponding air humidification and regulation processing according to the corresponding working mode.

[0055] Step S120: If the device is currently in the manual control mode, automatically obtain the current first target air parameter input by the user and the ambient air parameter of the environment where the device is currently located, and perform corresponding function adjustment 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] It can be understood that when it is determined through the above method steps that the device is currently in the manual control mode, the first target air parameter currently input by the user and the ambient air parameter of the environment where the device is currently located can be automatically obtained, and corresponding function adjustments can be performed 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. Generally speaking, when the user selects the manual control mode and does not input a new first target air parameter, the system will default the target air parameter input by the user last time as the first target air parameter, and control the device to perform corresponding function adjustments, so that the ambient air parameter is consistent with the first target air parameter. During the operation of the device, when the user inputs a new target air parameter, the system will adjust the new target air parameter as the first target air parameter, and control the device to perform corresponding function adjustments, so that the ambient air parameter is consistent with the first target air parameter.

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

[0058] It can be understood that when it is determined through the above method steps that the device is currently in the automatic control mode, the second target air parameter preset and matched by the system and the ambient air parameter of the environment where the device is currently located can be automatically obtained, and corresponding function adjustments can be performed according to the difference between the ambient air parameter and the second target air parameter, so that the ambient air parameter is consistent with the second target air parameter. Generally speaking, the second target air parameter preset and matched by the system can be specifically set in the system with reference to the national standard GB / T18883-2022 "Indoor Air Quality Standard" in advance. Generally, there are different parameter settings for different seasons. Therefore, when the device is currently in the automatic control mode, the system will first select the corresponding system setting according to the current season, that is, the second target air parameter preset and matched by the system. As pointed out in the national standard GB / T18883-2022 "Indoor Air Quality Standard", in the winter indoor air quality requirements, the temperature needs to be between 16°C and 24°C, and the relative humidity needs to be between 30% and 60%. Taking the average value as the standard, in the winter human comfort, therefore, for the system settings in winter, specifically, the target temperature value requirement is 20°C, and the relative humidity value requirement is 45%; and the target carbon dioxide concentration value requirement is below 1000 ppm (0.1% a).

[0059] In this way, through the above method steps, the fresh air humidification and regulation device can make the air parameters of the indoor environment where the fresh air humidification and regulation device 1 is located consistent with the corresponding target air parameters regardless of the operating mode, so as to meet the comfort requirements of various people, and further improve the comfort performance of the fresh air humidification device in terms of selection.

[0060] In some examples, the fresh air humidification and regulation device 1 in the embodiments of the present application is mainly used to adjust the temperature value, relative humidity value and carbon dioxide concentration value in the indoor air. Therefore, the above-mentioned first target air parameters may specifically include a first target temperature value, a first target relative humidity value and a first target carbon dioxide concentration value. Similarly, the ambient air parameters include an ambient temperature value, an ambient relative humidity value and an ambient carbon dioxide concentration value, and the second target air parameters include a second target temperature value, a second target relative humidity value and a second target carbon dioxide concentration value. At this time, as Figure 3 shown, the process of "performing corresponding function adjustment according to the difference between the ambient air parameters and the first target air parameters to make the ambient air parameters consistent with the first target air parameters" in the above method steps is specifically as follows:

[0061] Step S121: If there is a difference between the ambient temperature value and the first target temperature value, then according to the difference between the ambient temperature value and the first target temperature value, control the air pretreatment component to perform heating work and control the proportion of the air volume discharged between the air inlet and outlet and the air outlet, so that the ambient temperature value is consistent with the first target temperature value.

[0062] It can be understood that this method step is mainly used to ensure that the ambient temperature value is consistent with the first target temperature value. Generally, the implementation means is to control the air pretreatment component 120 to perform heating work and control the proportion of the air volume discharged between the air inlet and outlet 113 and the air outlet 112 according to the difference between the ambient temperature value and the first target temperature value. Among them, controlling the proportion of the air volume discharged between the air inlet and outlet 113 and the air outlet 112 can be achieved by controlling the rotation speed of the second fan 133. Taking the difference between the set ambient temperature value and the first target temperature value as α and the determination threshold as 5°C as an example, the above means may specifically be: when α≥5°C, reduce the rotation speed of the second fan 133 so that the air inlet and outlet 113 is the main air outlet; when α<5°C, increase the rotation speed of the second fan 133 so that the air outlet 112 is the air outlet and the air inlet and outlet 113 is the air inlet. In this way, through the above control means, while taking into account energy conservation and environmental protection, the ambient temperature value can be made to be consistent with the first target temperature value as soon as possible.

[0063] Step S122: If there is a difference between the environmental relative humidity value and the first target relative humidity value, then, based on the difference between the environmental relative humidity value and the first target relative humidity value, control the humidification treatment component to perform humidification work and control the proportion of the air volume discharged between the air inlet and outlet and the air outlet, so that the environmental relative humidity value is consistent with the first target relative humidity value.

[0064] It can be understood that the main purpose of this method step is to ensure that the environmental relative humidity value is consistent with the first target relative humidity value. The general implementation means is to control the humidification treatment component 130 to perform humidification work and control the proportion of the air volume discharged between the air inlet 113 and the air outlet 112 according to the difference between the environmental relative humidity value and the first target relative humidity value. Among them, controlling the proportion of the air volume discharged between the air inlet 113 and the air outlet 112 can be achieved by controlling the rotation speed of the second fan 133, that is, the rotation speed of the second fan 113 can be adjusted according to the difference σ between the environmental relative humidity value and the first target relative humidity value. Then, through the above means of control, while taking into account energy conservation and environmental protection, the environmental temperature value can be made to be consistent with the first target temperature value as soon as possible.

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

[0066]

[0067] Where: V, m, V o , d o , V i , d i are the total air volume, total air mass flow rate, fresh air volume, fresh air moisture content, return air volume and return air moisture content; ρ a , ρ l are the air density and liquid water density; m wo , m wi , m js , m ao , m ai are the 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 environmental carbon dioxide concentration value and the first target carbon dioxide concentration value, then, based on the difference between the environmental carbon dioxide concentration value and the first target carbon dioxide concentration value, control the proportion of the air intake volume between the fresh air inlet and the return air inlet, so that the environmental carbon dioxide concentration value is consistent with the first target carbon dioxide concentration value.

[0069] It can be understood that the steps of this method are mainly used to make the carbon dioxide concentration value consistent with the first target carbon dioxide concentration value. Generally, the implementation means is to control the proportion of the air intake volume between the fresh air inlet 115 and the return air inlet 114 according to the difference between the ambient carbon dioxide concentration value and the first target carbon dioxide concentration value. Among them, controlling the proportion of the air intake volume between the fresh air inlet 115 and the return air inlet 114 can be achieved by controlling the opening degree of the air valve, that is, the opening degree of the air valve 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 opening degree of the air valve can be increased to increase the proportion of fresh air. Then, through the above means of control, while taking into account energy conservation and environmental protection, the ambient carbon dioxide concentration value can be made consistent with the first target carbon dioxide concentration value.

[0070] Similarly, as Figure 3 shown, the process of executing the step of "performing corresponding function adjustment according to the difference between the ambient air parameters and the second target air parameters to make the ambient air parameters consistent with the second target air parameters" 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 according to the difference between the ambient temperature value and the second target temperature value, control the air pretreatment component to perform heating work and control the proportion of the air outlet volume between the air inlet and outlet and the air outlet, so that the ambient temperature value is consistent with the second target temperature value.

[0072] It can be understood that the specific steps of this method can refer to the above method step S121 and will not be elaborated here.

[0073] Step S132: If there is a difference between the ambient relative humidity value and the second target relative humidity value, then according to the difference between the ambient relative humidity value and the second target relative humidity value, control the humidification treatment component to perform humidification work and control the proportion of the air outlet volume between the air inlet and outlet and the air outlet, so that the ambient relative humidity value is consistent with the second target relative humidity value.

[0074] It can be understood that the specific steps of this method can refer to the above method step S122 and will not be elaborated here.

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

[0076] It can be understood that the specific steps of this method can refer to the above method step S123 and will not be elaborated here.
