[0038] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Considering that the humidity control function of air conditioners is poor, it affects the comfort of the indoor environment. In particular, when the air conditioner is running in heating mode in winter, the indoor air will become drier, and the comfort experience is poor. Therefore, it is often necessary to equip a humidifier for auxiliary humidification to adjust the indoor air humidity.

[0040] Related solutions typically incorporate ultrasonic or wet film humidification components within the air conditioner. However, these products are mostly suitable for cabinet units, requiring manual water addition, which is cumbersome, and the water tank is prone to bacterial growth, resulting in a poor consumer experience. Some manufacturers have implemented waterless humidification by installing a moisture-absorbing rotor in the outdoor unit that absorbs moisture from the air and then delivers the moisture indoors. This eliminates the need for consumers to add water, providing a more worry-free, pure, and relatively safe and healthy humidification option, making it an optimal choice for wall-mounted air conditioners. However, in waterless humidification solutions, the humidification outlet of the indoor unit's humidification pipe, like the fresh air outlet, is often located above the evaporator. This is to prevent the outdoor air from entering the room at a different temperature than the indoor air, which can affect indoor comfort. Consequently, the humid air must first pass through the indoor heat exchanger before being delivered to the room. Under special humidification conditions, such as cooling, condensation on the indoor heat exchanger is inevitable and discharged outdoors through the drainpipe, compromising humidification effectiveness. Consequently, waterless humidification solutions fail to account for the conflicts between humidification and cooling, resulting in limited humidification results.

[0041] Therefore, the solution of the present invention proposes a control method for an air conditioner, specifically a control method for an air conditioner with a humidification function, which determines the priority of operating the humidification mode and the air conditioning mode in combination with indoor and outdoor environmental parameters, and operates different humidification parameters in different modes to improve the comfort of the indoor environment.

[0042] According to an embodiment of the present invention, a method for controlling an air conditioner is provided. Figure 1 The flowchart of one embodiment of the method of the present invention is shown as follows. The air conditioner comprises a heat exchange module and a humidification module, wherein the heat exchange module is used to execute the heat exchange mode of the air conditioner, and the humidification module is used to execute the humidification mode of the air conditioner. The heat exchange module is used to realize the heat exchange function of the air conditioner in the heat exchange mode of the air conditioner, and the humidification module is used to realize the humidification function of the air conditioner in the humidification mode of the air conditioner. Specifically, the air conditioner comprises an outdoor unit and an indoor unit, wherein the humidification module is provided above the outdoor unit, and a humidification pipe (such as Figure 9 The humidifying pipe 5 shown); the refrigerant system composed of the heat exchange module such as a compressor, an outdoor heat exchanger and an indoor heat exchanger; Figure 9 The diagram is a schematic diagram of the structure of a humidifying air conditioner (i.e., a waterless humidifying air conditioner), wherein (a) is a schematic diagram of the structure of the outdoor unit and the humidifying module, and (b) is a schematic diagram of the structure of the indoor unit. Figure 9As shown, the solution of the present invention provides a humidifying air conditioner. The humidifying air conditioner includes an indoor unit and an outdoor unit, and the indoor unit has an air inlet, an evaporator 6, an indoor fan 7 and an air outlet. The air duct connected to the air inlet and the air outlet is provided with a temperature and humidity sensor for detecting the indoor ambient temperature and humidity, including a temperature sensor, a humidity sensor or a temperature and humidity sensor, etc. The outdoor unit has an air inlet, a condenser, a compressor, an outdoor fan and an air outlet. Furthermore, the outdoor unit has a humidifying module, which is located above the outdoor unit. In the solution of the present invention, as Figure 1 As shown, the control method of the air conditioner includes: steps S110 to S140.

[0043] At step S110, when the air conditioner is running after being powered on, such as when the heat exchange mode of the air conditioner, such as cooling mode or heating mode, is running after the air conditioner is powered on, the indoor environmental parameters of the air conditioner are obtained, the outdoor environmental parameters of the air conditioner are obtained, and the user instructions of the air conditioner are obtained.

[0044] In step S120 , it is determined whether the humidification mode of the air conditioner needs to be operated according to the indoor environmental parameters of the air conditioner and / or the user instruction of the air conditioner.

[0045] In step S130, if it is determined that the humidification mode of the air conditioner needs to be operated, the target humidification amount of the air conditioner and the priority mode between the humidification mode and the heat exchange mode of the air conditioner are determined according to the indoor environment parameters of the air conditioner.

[0046] In step S140 , in the priority mode between the humidification mode and the heat exchange mode of the air conditioner, the heat exchange module and the humidification module are controlled to operate according to the outdoor environment parameters of the air conditioner and the target humidification amount of the air conditioner.

[0047] The solution of the present invention proposes a control scheme for an air conditioner with a humidification function, which determines the operating parameters of the humidification module based on the operating parameters of the air conditioner to ensure that the cooling effect is given priority; determines the operating parameters of the air conditioner based on the operating parameters of the humidification module to ensure that the humidification effect is given priority, solves the problem of conflict between the humidification effect and the cooling effect, and improves the comfort of the indoor environment.

[0048] In some embodiments, the indoor environmental parameter of the air conditioner includes: the indoor environmental relative humidity of the air conditioner.

[0049] For the specific process of determining whether to operate the humidification mode of the air conditioner according to the indoor environmental parameters of the air conditioner and / or the user instruction of the air conditioner in step S120, please refer to the following exemplary description.

[0050] The following combination Figure 2 The flowchart of an embodiment of the method of the present invention for determining whether the humidification mode of the air conditioner needs to be run is shown, which further illustrates the specific process of determining whether the humidification mode of the air conditioner needs to be run in step S120, including: steps S210 to S230.

[0051] Step S210, determine whether the relative humidity of the indoor environment of the air conditioner is less than a preset humidity threshold, and determine whether the user instruction of the air conditioner includes a preset humidification instruction; wherein, the relative humidity of the indoor environment of the air conditioner is such as the relative humidity RH of the environment where the air conditioner is located, and the preset humidity threshold is such as the humidification preset threshold RH0.

[0052] In step S220, if it is determined that the relative humidity of the indoor environment of the air conditioner is less than the preset humidity threshold, it is determined that the humidification mode of the air conditioner needs to be operated regardless of whether the user instruction of the air conditioner includes a preset humidification instruction.

[0053] Step S230: If it is determined that the relative humidity of the indoor environment of the air conditioner is greater than or equal to a preset humidity threshold, then regardless of whether it is determined that the user instruction of the air conditioner includes a preset humidification instruction, it is determined that there is no need to run the humidification mode of the air conditioner; wherein, if it is determined that the user instruction of the air conditioner includes a preset humidification instruction, a prompt message is initiated that the relative humidity of the indoor environment of the air conditioner is within the set humidity range.

[0054] Figure 10 FIG. 1 is a flow chart of a humidification control method for a humidification air conditioner (i.e., a waterless humidification air conditioner). Figure 10 As shown, a humidification control method for a humidification air conditioner (i.e., a waterless humidification air conditioner) includes:

[0055] Step 1: Power on the air conditioner and run it, then proceed to step 2 or step 3.

[0056] Step 2: Obtain a humidification operation instruction from the user, and then proceed to step 3. The humidification operation instruction can be obtained by voice, remote control button, gesture, etc.

[0057] Step 3: Control the indoor temperature and humidity detection device to detect the relative humidity RH of the air conditioner environment in real time or periodically, and determine whether the humidification mode needs to be run: if so, execute step 4; otherwise, make the air conditioner run normally under non-humidification conditions.

[0058] Specifically, a preset humidification threshold RH0 is set. RH0 represents the lowest humidity for the default comfort level of the air conditioner or the optimal comfort humidity defined by the user. Preferably, RH0 is 30%-70%. When RH0 ≤ RH, it indicates that the indoor air humidity meets the current comfort requirements, and the air conditioner does not need to humidify and can directly operate in the consumer-set mode normally. In particular, when it is determined that humidification is not required but the humidification instruction comes from the user, methods such as voice push, panel display, and mobile phone push are needed to prompt the user that the current humidity is appropriate and humidification is not required, so as to avoid the user's doubts about the normal operation of the air conditioner function. When RH < RH0, it indicates that the indoor air humidity is low, and the humidification mode needs to be operated to increase the humidity and ensure the comfort of the indoor environment. The air conditioner continues to execute the next step, i.e., step 4.

[0059] In the solution of the present invention, according to the indoor environmental parameters of the air conditioner and / or the user instructions of the air conditioner, it is determined whether to operate the humidification mode of the air conditioner. If the humidification mode needs to be operated, the priority of the humidification mode and the air-conditioning mode is determined in combination with the indoor and outdoor environmental parameters, and different humidification parameters are operated in different modes to ensure the simultaneous comfort of the user's temperature and humidity.

[0060] In some embodiments, the indoor environmental parameters of the air conditioner include: the indoor environmental temperature of the air conditioner and the indoor environmental relative humidity of the air conditioner.

[0061] For the specific process of determining the target humidification amount of the air conditioner, and the priority mode between the humidification mode and the heat exchange mode of the air conditioner according to the indoor environmental parameters of the air conditioner in step S130, refer to the following exemplary description.

[0062] The following combines Figure 3 The schematic flowchart of an embodiment for determining the target humidification amount of the air conditioner, and the priority mode between the humidification mode and the heat exchange mode of the air conditioner in the method of the present invention shown in the figure further illustrates the specific process of determining the target humidification amount of the air conditioner, and the priority mode between the humidification mode and the heat exchange mode of the air conditioner in step S130, including: steps S310 to step S340.

[0063] In step S310, according to the target temperature of the air conditioner and the target humidity of the air conditioner, the target moisture content of the air conditioner is determined. Specifically, reference can be made to the relevant description of formula (1); wherein, the target temperature of the air conditioner is the target temperature T0 (i.e., the user-set temperature), the target humidity of the air conditioner is the target humidity RH0 (i.e., the optimal comfort humidity), and the target moisture content of the air conditioner is δ(T0, RH0).

[0064] Step S320, determining the actual moisture content of the air conditioner based on the indoor ambient temperature of the air conditioner and the indoor relative humidity of the air conditioner. For details, please refer to the relevant description of formula (1); wherein, the indoor ambient temperature of the air conditioner is such as the current temperature T of the environment where the air conditioner is located, the indoor relative humidity of the air conditioner is such as the relative humidity RH of the environment where the air conditioner is located, and the actual moisture content of the air conditioner is such as δ(T,RH).

[0065] Step S330: determining the difference between the target humidity of the air conditioner and the actual humidity of the air conditioner, and recording it as the target humidification amount of the air conditioner; the target humidification amount of the air conditioner is exemplified by the target humidification amount M.

[0066] Step S340 : determining a priority mode between the humidification mode of the air conditioner and the heat exchange mode of the air conditioner according to the target humidification amount of the air conditioner.

[0067] like Figure 10 As shown, a humidification control method for a humidification air conditioner (ie, a waterless humidification air conditioner) further includes: step 4, controlling the air conditioner to operate in a humidification mode, specifically including steps 41 and 42.

[0068] Step 41 : Determine the humidification mode and target humidification amount based on the indoor environmental parameters, and then execute step 42 .

[0069] Specifically, the indoor temperature and humidity detection device is controlled to obtain the current temperature T of the environment where the air conditioner is located, and determines the target humidification amount M in combination with the target temperature T0 (ie, the user-set temperature) and the target humidity RH0 (ie, the optimal comfort humidity).

[0070] It is easy for people in this field to understand that there is a certain corresponding relationship between air temperature, relative humidity and moisture content, which can be characterized and queried through the psychrometric diagram. In other words, knowing two of the parameters can be used to query and calculate the other parameter, that is, the air moisture content δ under current conditions can be calculated through temperature and relative humidity. Then, the target humidification amount M can be determined by combining the difference in moisture content before and after:

[0071] M=δ(T0,RH0)-δ(T,RH) (1).

[0072] The humidification mode can be further determined in combination with the size of the target humidification amount M.

[0073] Among them, the moisture content is calculated by temperature and relative humidity. Generally, the relevant parameters can be queried and obtained through the psychrometric chart. There is no fitting calculation formula, but there are corresponding equivalent calculation formulas as needed, for example:

[0074] Dew point temperature = (237.7*E2) / (17.27-E2);

[0075] E2=C2+D2;

[0076] C2 = (17.27*temperature) / (237.7+temperature);

[0077] D2 = LN[(relative humidity) / 100].

[0078] Moisture content = 3.703 + 0.286 * dew point + 0.009164 * dew point * dew point + 0.0001446 * dew point * dew point * dew point.

[0079] In the solution of the present invention, the air conditioner can determine the priority of operating the humidification mode and the air conditioning mode in combination with indoor and outdoor environmental parameters, and operate different humidification parameters in different modes to ensure the user's simultaneous comfort in temperature and humidity.

[0080] In some embodiments, the specific process of determining the priority mode between the humidification mode of the air conditioner and the heat exchange mode of the air conditioner according to the target humidification amount of the air conditioner in step S340 is described in the following exemplary embodiments.

[0081] The following combination Figure 4 The flowchart of an embodiment of determining the priority mode between the humidification mode of the air conditioner and the heat exchange mode of the air conditioner in the method of the present invention further illustrates the specific process of determining the priority mode between the humidification mode of the air conditioner and the heat exchange mode of the air conditioner in step S340, including: steps S410 to S430.

[0082] Step S410, determining whether the target humidification amount of the air conditioner is less than or equal to a preset humidification amount threshold; wherein the preset humidification amount threshold is, for example, a humidification mode determination threshold M0.

[0083] Step S420: If it is determined that the target humidification amount of the air conditioner is less than or equal to the preset humidification amount threshold, the heat exchange mode of the air conditioner is determined to be the priority mode, so as to give priority to the heat exchange mode of the air conditioner. Specifically, when the heat exchange mode of the air conditioner is given priority, the humidification mode of the air conditioner is synchronously run.

[0084] Step S430: If it is determined that the target humidification amount of the air conditioner is greater than the preset humidification amount threshold, the humidification mode of the air conditioner is determined to be the priority mode, so as to give priority to running the humidification mode of the air conditioner. Specifically, when giving priority to running the humidification mode of the air conditioner, the heat exchange mode of the air conditioner is also run.

[0085] like Figure 10As shown, a humidification control method for a humidifying air conditioner (i.e., a waterless humidifying air conditioner) further includes: in step 41, the humidification mode can be further determined based on the target humidification amount M. Air temperature, relative humidity, moisture content, etc. have corresponding relationships and can be mathematically calculated equivalently or presented in a single diagram, called a psychrometric diagram. Two of these parameters can be used to determine the other parameter. Specifically, M0 is defined as the humidification mode judgment threshold. When M ≤ M0, it indicates that the current environmental parameters are not significantly different from the optimal comfort parameters. The air conditioner can prioritize the air conditioner mode (temperature adjustment) and simultaneously operate the humidification mode (humidity adjustment). Humidity adjustment emphasizes humidification behavior and is implemented through the humidification module on the top of the outdoor unit. It can operate independently. However, when the moisture is delivered to the room and encounters the indoor heat exchanger, if it is cooling, it will be condensed and absorbed, resulting in poor humidification effect. Temperature adjustment priority means that temperature adjustment is the main focus, humidification is performed simultaneously, and the absorption part is ignored. When M>M0, it means that the current environmental parameters are significantly different from the optimal comfort parameters. It is necessary to prioritize the humidification mode to meet comfort requirements before considering temperature control needs. The purpose of prioritizing the humidification mode is to ensure the humidification effect. The dew point can be calculated based on the moisture parameters entering the humidification system. As long as the air conditioner pipe temperature is kept above this temperature, the moisture will not condense upon contact with the low-temperature pipes, i.e., there will be no moisture loss. Conversely, because the pipe temperature must be controlled, the heat exchange capacity will be affected to a certain extent, resulting in limited temperature control needs. The moisture entering the room through humidification will be condensed and absorbed by the fins of the air conditioner heat exchanger (i.e., the indoor heat exchanger), causing a decrease in humidification efficiency. If the temperature is below the dew point, the hot air will condense upon contacting the cold surface. In other words, humidification and cooling are in conflict, and one needs to be selected based on the situation. Based on this, when the calculated target humidification amount M is low, that is, the current environmental parameters are not much different from the comfort level, the air conditioner mode can be used as the main mode and humidification can be performed simultaneously. If the calculated target humidification amount M is large, that is, the current environment is very dry and uncomfortable, the humidification mode needs to be prioritized at this time, that is, the air conditioner cooling parameters need to be controlled so that it does not cause condensation loss and other problems during humidification, affecting the humidification effect.

[0086] In some embodiments, the priority mode between the humidification mode of the air conditioner and the heat exchange mode of the air conditioner includes: the heat exchange mode of the air conditioner is the priority mode, or the humidification mode of the air conditioner is the priority mode; the outdoor environment parameters of the air conditioner include: the outdoor environment temperature of the air conditioner, and the outdoor environment relative humidity of the air conditioner.

[0087] In step S140, in the priority mode between the humidification mode of the air conditioner and the heat exchange mode of the air conditioner, the operation of the heat exchange module and the humidification module is controlled according to the outdoor environment parameters of the air conditioner and the target humidification amount of the air conditioner, including: a process of determining the humidification operation parameters of the humidification module, specifically including: a process of determining the humidification operation parameters of the humidification module when the humidification mode of the air conditioner is the priority mode, and a process of determining the humidification operation parameters of the humidification module when the heat exchange mode of the air conditioner is the priority mode.

[0088] The following combination Figure 5 The flowchart of an embodiment of determining the humidification operating parameters of the humidification module in the method of the present invention further illustrates the specific process of determining the humidification operating parameters of the humidification module in step S140, including: steps S510 to S550.

[0089] Step S510, when the humidification mode of the air conditioner is the priority mode, or when the heat exchange mode of the air conditioner is the priority mode, the operating parameters of the humidification module are determined according to the outdoor ambient temperature of the air conditioner and the outdoor relative humidity of the air conditioner. For details, please refer to the relevant description of formula (3); wherein the outdoor ambient temperature of the air conditioner is the ambient temperature T 外 , the outdoor environment relative humidity of the air conditioner is such as relative humidity RH 外 .

[0090] Step S520: Determine the humidification capacity of the humidification module according to the operating parameters of the humidification module. For details, please refer to the relevant description of formula (2); wherein, the humidification capacity of the humidification module is such as the humidification capacity J of the humidification module.

[0091] Step S530, determining the humidification speed of the humidification module according to the outdoor ambient temperature of the air conditioner, the outdoor relative humidity of the air conditioner, and the humidification capacity of the humidification module. For details, please refer to the relevant description of formula (3); wherein, the humidification speed of the humidification module is such as the moisture content k delivered into the room per unit time.

[0092] In step S540, a ratio of the target humidification amount of the air conditioner to the humidification speed of the humidification module is used as the operating time of the humidification module; and the operating parameters of the humidification module and the operating time of the humidification module are used as the humidification operating parameters of the humidification module. The operating time of the humidification module is as follows: the humidification module operating time t; and the humidification operating parameters of the humidification module include: the operating parameters of the humidification module and the operating time of the humidification module.

[0093] Step S550: Control the humidification module to operate according to the humidification operating parameters of the humidification module.

[0094] like Figure 10 As shown, a humidification control method for a humidifying air conditioner (ie, a waterless humidifying air conditioner) further includes: step 42, running different humidification modes according to different needs, specifically including steps 421 and 422.

[0095] Step 421 When the humidification mode is determined to be the priority, the air conditioner is controlled to operate according to the following procedures:

[0096] In step 421, it includes: ① determining humidification operation parameters based on outdoor environmental parameters and target humidification amount.

[0097] The outdoor environmental parameter is the ambient temperature T 外 and relative humidity RH 外 The humidification operation parameters include the operation parameters of the humidification module and the humidification operation time t. The operation parameters of the humidification module include the rotation speed r of the moisture absorption fan 1. 吸 , humidification fan 4 speed r 加 , wheel 2 speed r, heating temperature T 热 Outdoor environmental parameters determine the air humidity content. Generally, the higher the humidity content, the easier it is to adsorb and the greater the adsorption capacity. At the same time, temperature also affects the adsorption rate. Contrary to desorption, the higher the outdoor ambient temperature, the more difficult it is to adsorb. Therefore, based on the outdoor environmental parameters, we can optimize the operating parameters of the humidification module to maximize its humidification capacity. For example, if the ambient temperature is low and the moisture absorption capacity is poor, it may be necessary to increase the wind speed to accelerate the moisture absorption capacity and simultaneously increase the temperature to ensure the desorption effect.

[0098] It is easy for people in this field to understand that the ability of the moisture-absorbing wheel 2 to absorb moisture is closely related to the rotation speed of the moisture-absorbing fan 1 (i.e., wind speed, which determines the air content passing through the wheel 2. Generally, the higher the rotation speed, the more air volume passing through the wheel 2 and the greater the adsorption capacity) and the speed of the wheel 2 (which determines the contact and adsorption time between the moist air and the wheel 2. Generally, the slower the rotation speed of the moisture-absorbing fan 1, the greater the adsorption capacity of the wheel 2, but the fewer cycles per unit time, and the smaller the adsorption capacity). The ability to release moisture is closely related to the heating temperature (which determines the desorption rate of moisture from the wheel 2. Generally, the higher the temperature, the faster the desorption), the rotation speed of the humidifying fan 4 (i.e., wind speed, which determines the air content carrying moisture passing through the wheel 2. Generally, the higher the wind speed, the greater the humidification capacity) and the speed of the wheel 2 (which determines the contact time between the air and the wheel 2. Generally, the slower the rotation speed, the longer the contact time, the relatively higher the content of moist air carried, and the greater the humidification capacity). The above-mentioned ability to absorb moisture and the ability to release moisture jointly determine the humidification capacity of the humidification module. Here, the humidification capacity of the humidification module is defined as J, that is:

[0099] J=f(r 吸 , r 加, r, T 热 ) (2).

[0100] Formula (2) is only an explanation of the control relationship of humidification capacity. If necessary, the functional relationship can be refined in combination with test data. Generally, the effect and the influence of different parameters are determined by actual measurement and orthogonal experiments. Taking into account some special situations, such as avoiding humidification too quickly to produce condensation, it is necessary to reasonably control the humidification capacity. Therefore, optionally, the humidification capacity of the humidification module can be controlled by adjusting any of the above parameters, and there is a certain equivalence between the above parameters. For example, increasing the heating temperature is equivalent to increasing the speed of the humidification fan 4. The specific adjustment and control can be carried out according to the needs and actual conditions. For example, it is known that increasing the heating temperature or increasing the speed of the humidification fan can improve the humidification capacity. When the external humidity content is large, the normal operation of the humidification mode may cause the moisture concentration generated by humidification to be too high, which is easy to form condensation inside the humidification pipe and cause water pollution. At this time, it is necessary to appropriately limit the humidification capacity. This can be achieved by reducing the heating temperature or by reducing the speed of the humidification fan. The specific reduction can be obtained in advance through experiments, and vice versa. Of course, it is usually hoped that the humidification is as fast as possible. Therefore, it is preferred that the operating parameters of the humidification module are the optimal fixed values ​​(i.e., r 吸 ,r 加 ,r,T 热 , J are fixed values). At this point, the humidification module can maximize its humidification capacity and meet the user's humidification needs as quickly as possible. The above optimal fixed values ​​can be obtained through experiments or theoretical calculations.

[0101] In addition, outdoor environmental parameters (i.e. temperature and relative humidity, which together determine the moisture content of the air. Generally, the higher the moisture content, the easier the adsorption and the greater the adsorption amount. At the same time, temperature also affects the adsorption rate. Contrary to desorption, the higher the temperature, the more difficult the adsorption) will also affect the humidification effect of the humidification module.

[0102] In summary, the humidification capacity of the humidification module and the outdoor environmental parameters jointly determine the speed (or effect) of the humidification module on the indoor humidification. Here, k (the moisture content delivered to the room per unit time) is used to characterize it, that is:

[0103] k=f(T 外 , RH 外 , r 吸 , r 加 , r, T 热 )=f(T 外 , RH 外 , J) (3).

[0104] In particular, when J is a constant, the humidification speed k is only related to the outdoor environmental parameters. That is, for different outdoor environmental conditions, the humidification module has different humidification speeds. Formula (3) only illustrates the influence of the humidification speed. If necessary, the functional relationship can be refined by combining test data. Most of the time, the effect and the influence of different parameters are determined through actual measurement using methods such as orthogonal experiments.

[0105] Furthermore, combined with the target humidification amount, the humidification module operating time t can be obtained as:

[0106] t=M / k (4).

[0107] Therefore, the humidification speed of the humidification module can be determined by the outdoor environmental parameters, and the humidification operation time can be further determined by combining the target humidification amount. The target humidification amount divided by the humidification speed k equals the time t required to reach the target humidification amount.

[0108] In the solution of the present invention, the air conditioner can determine the priority of operating the humidification mode and the air-conditioning mode based on indoor and outdoor environmental parameters, and operate different humidification parameters in different modes to ensure the user's simultaneous comfort of temperature and humidity. Thus, it solves the problem that the humidification solution in the relevant solution does not consider the conflict between humidification and cooling, resulting in insufficient effective humidification and limited humidification effect.

[0109] In some embodiments, the humidification module includes: a moisture absorption fan 1, a humidification fan 4, a rotor 2, and a heating device 3; a humidification pipe, such as a humidification pipe 5, is provided in the indoor unit; the operating parameters of the humidification mode include at least one of the following: the speed of the moisture absorption fan 1, the speed of the humidification fan 4, the speed of the rotor 2, and the heating temperature of the heating device 3, such as the speed of the moisture absorption fan 1 r 吸 , humidification fan 4 speed r 加 , wheel 2 speed r, heating temperature T 热 .

[0110] like Figure 9As shown, the humidification module includes a dehumidifying fan 1, a humidifying fan 4, a rotor 2, and a heating device 3. The dehumidifying fan 1 is used to draw humid outdoor air into the rotor 2, where it absorbs moisture and becomes dry air, which is then discharged outdoors. The rotor 2 is made by loading a hygroscopic material such as zeolite molecular sieve or metal-organic framework (MOF) onto the surface of a porous honeycomb carrier material such as glass fiber or ceramic fiber. It absorbs moisture from the air in an adsorption zone and then rotates to a desorption zone where it releases the absorbed moisture under high-temperature airflow. The heating device 3 is a positive temperature coefficient (PTC) or infrared heater that heats the rotor 2 (or air) to a high temperature, enabling moisture desorption from the rotor 2. The humidifying fan 4 is used to pass outdoor air through the heating device 3 and rotor 2, carrying the humidified air into the room. The indoor unit includes a humidification duct (such as the humidification tube 5), the outlet of which is located above the evaporator 6. The outdoor wet air enters the room through the humidification pipe, passes through the air outlet, and is temperature-controlled by the heat exchanger (such as the evaporator 6) before being sent to the indoor space to achieve humidification. The humidification module is equipped with a temperature and humidity sensor for detecting the outdoor ambient temperature and humidity, including a temperature sensor, a humidity sensor, or a temperature and humidity sensor.

[0111] In step S140, in the priority mode between the humidification mode and the heat exchange mode of the air conditioner, the operation of the heat exchange module and the humidification module is controlled according to the outdoor environment parameters of the air conditioner and the target humidification amount of the air conditioner. It also includes: when the humidification mode of the air conditioner is the priority mode, the heat exchange operation parameters of the heat exchange module are adjusted based on the humidification operation parameters of the humidification module. Specifically, when the humidification mode of the air conditioner is the priority mode, after controlling the humidification module to operate according to the humidification operation parameters of the humidification module, the heat exchange operation parameters of the heat exchange module are adjusted based on the humidification operation parameters of the humidification module.

[0112] The specific process of adjusting the heat exchange operating parameters of the heat exchange module based on the humidification operating parameters of the humidification module is described in the following exemplary embodiments.

[0113] The following combination Figure 6 The flowchart of an embodiment of adjusting the heat exchange operating parameters of the heat exchange module in the method of the present invention further illustrates the specific process of adjusting the heat exchange operating parameters of the heat exchange module in step S140, including: steps S610 to S640.

[0114] Step S610, determining the outlet air temperature of the humidification pipe according to the outdoor ambient temperature of the air conditioner and the heating temperature of the heating device 3 in the humidification operation parameters of the humidification module, for details, see the relevant description of formula (5).

[0115] Step S620, according to the outlet air temperature of the humidification pipe and the humidification speed of the humidification module in the humidification operation parameters of the humidification module, specifically refer to the relevant description of formula (6), to determine the outlet air relative humidity of the humidification pipe; wherein the outlet air temperature of the humidification pipe is such as the outlet moisture temperature T of the humidification pipe 5 湿 The relative humidity of the outlet air of the humidification pipe is such as the relative humidity RH of the outlet of humidification pipe 5 湿 .

[0116] Step S630, determining the outlet dew point temperature of the humidifying pipe according to the outlet air temperature of the humidifying pipe and the relative humidity of the outlet air of the humidifying pipe, for details, please refer to the relevant description of formula (7); wherein, the outlet dew point temperature of the humidifying pipe is such as the dew point temperature T 露 .

[0117] Step S640, adjust the heat exchange operating parameters of the heat exchange module so that during the operation time of the humidification module, the pipe temperature of the indoor heat exchanger in the heat exchange module is greater than the outlet dew point temperature of the humidification pipe. The heat exchange operating parameters of the heat exchange module include compressor frequency, speed of indoor fan 7, etc. The pipe temperature of the indoor heat exchanger is such as the pipe temperature T 管 .

[0118] like Figure 10 As shown, a humidification control method for a humidification air conditioner (ie, a waterless humidification air conditioner) further includes: in step 421, it also includes: ② adjusting the operating parameters of the air conditioner based on the humidification operating parameters.

[0119] The operating parameters of the air conditioner are mainly the temperature of the air conditioner pipe T 管 , detected by the system's own temperature sensing package.

[0120] Specifically, the air conditioner is controlled to determine the outlet temperature of the humidifying pipe 5 T according to the humidification operation parameters. 湿 and relative humidity RH 湿 , the humidity temperature T 湿 and outer ring temperature T 外 and heating temperature T 热 Relevant, namely:

[0121] T 湿 =f(T 外 , T 热 ) (5).

[0122] Formula (5) only explains the relationship between humidity and temperature. If the air comes from outside, the outdoor temperature determines the initial temperature of the humidity, and the electric heating temperature determines how much the humidity rises from the initial temperature. Therefore, the simplest relationship is: T湿 =T 外 +T 热 +k, k is the coefficient. The humidity comes from the outside, and enters the room after being heated and absorbed by the wheel 2, so the humidity temperature is related to the external temperature and the heating temperature. The relative humidity and temperature T 湿 It is related to the humidification speed k, that is:

[0123] RH 湿 =f(T 湿 ,k) (6).

[0124] Formula (6) is merely a description of the relationship. Air temperature, relative humidity, and moisture content are related. Therefore, relative humidity is related to temperature and moisture content, while moisture content is related to the humidification rate. Theoretically, the faster the humidification, the more moist air enters, and the correspondingly higher the air moisture content. As mentioned above, relative humidity is related to temperature and moisture content, while moisture content is related to the humidification rate, that is, the amount of moisture delivered to the room.

[0125] Optionally, the above parameters can also be directly detected and obtained by directly setting a temperature and humidity detection device at the outlet of the humidification tube 5.

[0126] Furthermore, combined with the outlet temperature T of the humidifying tube 5, 湿 and relative humidity RH 湿 The dew point temperature T at this time can be determined 露 ,Right now:

[0127] T 露 =f(T 湿 , RH 湿 ) (7).

[0128] There is a corresponding relationship between air temperature, relative humidity, and moisture content, which can be calculated mathematically or plotted on a graph called a psychrometric diagram. Through the temperature curve and relative humidity curve on this graph, we can also obtain the dew point temperature under these conditions (when the relative humidity is 100%). When the temperature is lower than this dew point temperature, condensation will occur.

[0129] Since humidification is the priority at this time, in order to ensure that moisture is not condensed and collected by the heat exchanger, it is necessary to control the temperature T of the air conditioner inner tube. 管 During the humidification operation time tT 管 >T 露 , that is, T 管 >T 露 The air conditioner is regulated by controlling system parameters such as the compressor frequency and indoor fan speed. In theory, a higher compressor frequency and lower fan speed will result in lower pipe temperatures during cooling. Therefore, pipe temperature control can be achieved by applying similar principles, such as appropriately controlling the compressor frequency to a minimum and the indoor fan speed to a minimum.

[0130] In the solution of the present invention, the operating parameters of the air conditioner are adjusted based on the humidification operating parameters, with humidification being given priority, thereby ensuring that moisture is not condensed and collected by the heat exchanger, thereby improving the effect of priority humidification.

[0131] In some embodiments, in the priority mode between the humidification mode and the heat exchange mode of the air conditioner, the operation of the heat exchange module and the humidification module is controlled according to the outdoor environment parameters of the air conditioner and the target humidification amount of the air conditioner, and also includes: when the heat exchange mode of the air conditioner is the priority mode, the humidification operation parameters of the humidification module are adjusted based on the heat exchange operation parameters of the heat exchange module, specifically as follows: when the heat exchange mode of the air conditioner is the priority mode, after controlling the humidification module to operate according to the humidification operation parameters of the humidification module, the humidification operation parameters of the humidification module are adjusted based on the heat exchange operation parameters of the heat exchange module.

[0132] The specific process of adjusting the humidification operating parameters of the humidification module based on the heat exchange operating parameters of the heat exchange module is described in the following exemplary embodiments.

[0133] The following combination Figure 7 The flowchart of an embodiment of adjusting the humidification operating parameters of the humidification module in the method of the present invention further illustrates the specific process of adjusting the humidification operating parameters of the humidification module in step S140, including: steps S710 to S750.

[0134] Step S710, determining the outlet air temperature of the humidification pipe according to the outdoor ambient temperature of the air conditioner and the heating temperature of the heating device 3 in the humidification operation parameters of the humidification module, for details, see the relevant description of formula (5).

[0135] Step S720, according to the outlet air temperature of the humidification pipe and the humidification speed of the humidification module in the humidification operation parameter of the humidification module, specifically refer to the relevant description of formula (6), determine the outlet air relative humidity of the humidification pipe; wherein the outlet air temperature of the humidification pipe is such as the outlet moisture temperature T of the humidification pipe 5 湿 The relative humidity of the outlet air of the humidification pipe is such as the relative humidity RH of the outlet of humidification pipe 5 湿 .

[0136] Step S730: Determine the outlet dew point temperature of the humidifying pipe according to the outlet air temperature of the humidifying pipe and the relative humidity of the outlet air of the humidifying pipe. For details, refer to the relevant description of formula (7). And determine the outlet air moisture content of the humidifying pipe according to the outlet air temperature of the humidifying pipe and the relative humidity of the outlet air of the humidifying pipe. For details, refer to the relevant description of formula (1); wherein, the outlet dew point temperature of the humidifying pipe is such as the dew point temperature T 露 The outlet air humidity of the humidification pipe is such as the real-time air humidity δ 湿 .

[0137] Step S740, based on the moisture content of the air at the outlet of the humidification pipe, the time period during which the pipe temperature of the indoor heat exchanger in the heat exchange module is less than or equal to the outlet dew point temperature of the humidification pipe, and the difference between the outlet dew point temperature of the humidification pipe and the pipe temperature of the indoor heat exchanger in the heat exchange module, the humidification loss of the heat exchange module is determined. For details, please refer to the relevant description of formula (8); wherein the pipe temperature of the indoor heat exchanger is such as the pipe temperature T 管 The time period during which the pipe temperature of the indoor heat exchanger in the heat exchange module is less than or equal to the outlet dew point temperature of the humidification pipe is T 管 ≤T 露 The time period t', the difference between the outlet dew point temperature of the humidification pipe and the pipe temperature of the indoor heat exchanger in the heat exchange module is the difference between the pipe temperature and the dew point temperature T 露 -T 管 The loss humidification capacity of the heat exchange module is such as the loss humidification capacity M 损 .

[0138] Step S750: The ratio of the humidification loss of the heat exchange module to the humidification speed of the humidification module is used as the humidification operation extension time of the humidification module; and the sum of the operation time of the humidification module and the humidification operation extension time of the humidification module is used as the new operation time of the humidification module. 延 =M 损 / k, the new running time of the humidification module is t+t, the actual running time of the air conditioner humidification is 延 .

[0139] like Figure 10 As shown, a humidification control method for a humidification air conditioner (ie, a waterless humidification air conditioner) further includes: step 422, When the air conditioner mode is determined to be the priority, the air conditioner is controlled to operate according to the following procedures:

[0140] ① Determine the humidification operation parameters based on the outdoor environmental parameters and the target humidification amount.

[0141] Specifically, in combination with the above, the humidification capacity of the humidification module and the outdoor environmental parameters jointly determine the indoor humidification speed k of the humidification module, that is:

[0142] k=f(T 外 , RH 外 , r 吸 , r 加 , r, T 热 )=f(T 外 , RH 外 , J) (3).

[0143] Further combined with the target humidification amount M, the theoretical operating time t of the humidification module can be obtained:

[0144] t=M / k (4).

[0145] ② Adjust the humidification operating parameters based on the operating parameters of the air conditioner.

[0146] The operating parameters of the air conditioner are mainly the temperature of the air conditioner pipe T 管 .

[0147] Specifically, in combination with the above, the air conditioner can be controlled to determine the outlet temperature of the humidifying pipe 5 T by combining the humidification operation parameters. 湿 and relative humidity RH 湿 , and thus determine the dew point temperature T 露 and the air humidity δ under current conditions 湿 , see formula (5), formula (6), formula (7) and formula (1) for details.

[0148] Since the air conditioner is prioritized at this time, the pipe temperature in the air conditioner may be less than or equal to the dew point temperature of the humidified air within a certain time period t', that is, T 管 ≤T 露 At this point, the moisture delivered by the humidification tube 5 will be partially condensed and collected, resulting in the actual humidification rate being lower than the target rate. To achieve the target humidification effect, it is necessary to adjust the humidification operating parameters, such as extending the humidification time or increasing the humidification speed. Since the humidification module is generally operating at its maximum capacity, and the various parameters of the humidification module affect each other, making adjustment difficult, the preferred correction method is to extend the humidification time.

[0149] Here we define the loss of humidification as M 损 , then the loss of humidification capacity M 损 and temperature difference (i.e. the difference between pipe temperature and dew point temperature T 露 -T 管 ), real-time air humidity δ 湿 and T 管 ≤T 露 The time period t' is related to

[0150] M 损 =f(δ 湿 , t', T 露 -T 管 ) (8).

[0151] Among them, the tube temperature T 管 It can be directly monitored, the dew point temperature T 露 It can also be obtained through relevant calculations, thus also determining the time the pipe temperature remains below the dew point. Humidification loss is the amount of moisture lost due to condensation after the moist air enters the air conditioner because the pipe temperature remains below the dew point. The speed at which moist air condenses depends on the moisture content and temperature difference. Theoretically, the greater the moisture content and the greater the temperature difference, the stronger the condensation driving force and the faster the condensation. The condensation rate combined with the condensation time can be used to calculate humidification loss.

[0152] It is easy to understand that compared with the indoor environment, the outdoor environment is open and infinite, so its environmental parameters will not change much, and the operating parameters of the humidification module are generally fixed. Therefore, when the outdoor environment is determined, its humidification speed is also fixed, that is, T 露 , δ 湿 are all constant values. However, the pipe temperature changes continuously as the air conditioner runs, and becomes larger and larger, that is, T 露 -T 管 As the difference in temperature decreases, the amount of condensed water decreases. Therefore, the above process calculates the total amount of condensed water under different pipe temperature conditions during time t'. Due to the air conditioner mode priority, there are periods of time when the pipe temperature falls below the dew point, during which condensation occurs. The amount of condensation depends on the temperature difference and the humidity content at that time. The total amount of condensation during the entire time period when the pipe temperature falls below the dew point is the total humidification loss.

[0153] Further combined with the loss of humidification capacity M 损 (i.e. the second target humidification amount) can be obtained by extending the humidification operation time t 延 for:

[0154] t 延 =M 损 / k (9).

[0155] Since T 管 >T 露 Therefore, there is no attenuation problem during humidification over an extended period of time. Humidification capacity M 损 Divided by the humidification speed k equals the time t required to reach the humidification amount 延 .

[0156] In short, based on the air conditioner operating internal pipe temperature T 管 The actual humidification operation time of the air conditioner can be determined as t+t 延 .

[0157] Based on steps 421 and 422, the humidification module is controlled to operate according to the corresponding mode and parameters. The air conditioner is controlled to operate according to the corresponding mode and parameters. Specifically, the air conditioner is controlled to determine whether to operate the humidification mode based on user instructions or real-time monitoring of environmental parameters. When humidification is determined to be necessary, the air conditioner determines the humidification amount and whether to prioritize humidification or air conditioning based on the environmental parameters. The humidification module is then controlled to operate according to the corresponding mode and parameters to ensure the user's temperature and humidity are both comfortable.

[0158] The technical solution of this embodiment is adopted, by targeting an air conditioner with a humidification function, that is, a humidification module is provided above the outdoor unit, and a humidification pipe (such as a humidification pipe) connected to the humidification module is provided in the indoor unit. Figure 9 The humidification tube 5 shown in FIG. 5 ) is provided with a humidification module having a rotating wheel (such as Figure 9 The wheel 2 shown in FIG), the moisture absorption fan (such as Figure 9 The dehumidifying fan 1 shown in FIG. 1 ) and the humidifying device (such as Figure 9 The humidifying device 3 shown) and the humidifying fan (such as Figure 9 humidifying fan 4 shown); after the air conditioner is powered on, when it is determined that the humidification mode needs to be run according to the environmental parameters of the air conditioner, or when it is determined that the humidification mode needs to be run after receiving a humidification operation instruction sent by the user, the humidification amount and whether the humidification priority or the heat exchange priority are determined according to the environmental parameters of the air conditioner to determine the humidification parameters, and the humidification module is controlled to run the humidification parameters; thereby, by taking into account both heat exchange and humidification in the humidification mode, the indoor temperature and humidity are improved while the comfort is maintained.

[0159] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for the air conditioner is also provided. Figure 8 The structure diagram of an embodiment of the device of the present invention is shown. The air conditioner has a heat exchange module and a humidification module, the heat exchange module is used to execute the heat exchange mode of the air conditioner, the humidification module is used to execute the humidification mode of the air conditioner, the heat exchange module is used to realize the heat exchange function of the air conditioner in the heat exchange mode of the air conditioner, and the humidification module is used to realize the humidification function of the air conditioner in the humidification mode of the air conditioner; specifically: the air conditioner has an outdoor unit and an indoor unit, the humidification module is provided above the outdoor unit, and a humidification pipe (such as Figure 9 The humidifying pipe 5 shown); the refrigerant system composed of the heat exchange module such as a compressor, an outdoor heat exchanger and an indoor heat exchanger; Figure 9 The diagram is a schematic diagram of the structure of a humidifying air conditioner (i.e., a waterless humidifying air conditioner), wherein (a) is a schematic diagram of the structure of the outdoor unit and the humidifying module, and (b) is a schematic diagram of the structure of the indoor unit. Figure 9As shown, the solution of the present invention provides a humidifying air conditioner. The humidifying air conditioner includes an indoor unit and an outdoor unit, and the indoor unit has an air inlet, an evaporator 6, an indoor fan 7 and an air outlet. The air duct connected to the air inlet and the air outlet is provided with a temperature and humidity sensor for detecting the indoor ambient temperature and humidity, including a temperature sensor, a humidity sensor or a temperature and humidity sensor, etc. The outdoor unit has an air inlet, a condenser, a compressor, an outdoor fan and an air outlet. Furthermore, the outdoor unit has a humidifying module, which is located above the outdoor unit. In the solution of the present invention, as Figure 9 As shown, the control device of the air conditioner includes: an acquisition unit 102 and a control unit 104.

[0160] The acquisition unit 102 is configured to acquire indoor environmental parameters of the air conditioner, acquire outdoor environmental parameters of the air conditioner, and acquire user instructions for the air conditioner when the air conditioner is powered on and in operation, such as when the air conditioner is powered on and in a heat exchange mode, such as a cooling mode or a heating mode. The specific functions and processing of the acquisition unit 102 are described in step S110.

[0161] The control unit 104 is configured to determine whether to operate the humidification mode of the air conditioner according to the indoor environmental parameters of the air conditioner and / or the user instruction of the air conditioner. The specific functions and processing of the control unit 104 are shown in step S120.

[0162] The control unit 104 is further configured to, if it is determined that the air conditioner needs to operate in the humidification mode, determine a target humidification amount for the air conditioner and a priority mode between the humidification mode and the heat exchange mode of the air conditioner based on the indoor environment parameters of the air conditioner. The specific functions and processing of the control unit 104 are further described in step S130.

[0163] The control unit 104 is further configured to control the operation of the heat exchange module and the humidification module in a priority mode between the humidification mode and the heat exchange mode of the air conditioner, based on the outdoor environment parameters of the air conditioner and the target humidification amount of the air conditioner. The specific functions and processing of the control unit 104 are further described in step S140.

[0164] The solution of the present invention proposes a control scheme for an air conditioner with a humidification function, which determines the operating parameters of the humidification module based on the operating parameters of the air conditioner to ensure that the cooling effect is given priority; determines the operating parameters of the air conditioner based on the operating parameters of the humidification module to ensure that the humidification effect is given priority, solves the problem of conflict between the humidification effect and the cooling effect, and improves the comfort of the indoor environment.

[0165] In some embodiments, the indoor environmental parameter of the air conditioner includes: the indoor environmental relative humidity of the air conditioner.

[0166] The control unit 104 determines whether to operate the humidification mode of the air conditioner according to the indoor environmental parameters of the air conditioner and / or the user instruction of the air conditioner, including:

[0167] The control unit 104 is further configured to determine whether the relative humidity of the indoor environment of the air conditioner is less than a preset humidity threshold, and to determine whether the user command for the air conditioner includes a preset humidification command; wherein the relative humidity of the indoor environment of the air conditioner is, for example, the relative humidity RH of the environment in which the air conditioner is located, and the preset humidity threshold is, for example, the preset humidification threshold RH0. The specific functions and processing of the control unit 104 are further described in step S210.

[0168] The control unit 104 is further configured to determine that the relative humidity of the indoor environment of the air conditioner is less than a preset humidity threshold, regardless of whether the user instruction of the air conditioner includes a preset humidification instruction, and to determine that the air conditioner needs to operate in a humidification mode. The specific functions and processing of the control unit 104 are further described in step S220.

[0169] The control unit 104 is further configured to, if it is determined that the relative humidity of the indoor environment of the air conditioner is greater than or equal to a preset humidity threshold, determine that the humidification mode of the air conditioner is not required, regardless of whether the user instruction of the air conditioner includes a preset humidification instruction; and if it is determined that the user instruction of the air conditioner includes a preset humidification instruction, initiate a prompt message indicating that the relative humidity of the indoor environment of the air conditioner is within a preset humidity range. The specific functions and processing of the control unit 104 are further described in step S230.

[0170] Figure 10 FIG. 1 is a flow chart of a humidification control method for a humidification air conditioner (i.e., a waterless humidification air conditioner). Figure 10 As shown, a humidification control method for a humidification air conditioner (i.e., a waterless humidification air conditioner) includes:

[0171] Step 1: Power on the air conditioner and run it, then proceed to step 2 or step 3.

[0172] Step 2: Obtain a humidification operation instruction from the user, and then proceed to step 3. The humidification operation instruction can be obtained by voice, remote control button, gesture, etc.

[0173] Step 3: Control the indoor temperature and humidity detection device to detect the relative humidity RH of the air conditioner environment in real time or periodically, and determine whether the humidification mode needs to be run: if so, execute step 4; otherwise, make the air conditioner run normally under non-humidification conditions.

[0174] Specifically, a humidification preset threshold RH0 is set. RH0 represents the lowest humidity for the default comfort level of the air conditioner or the optimal comfort humidity defined by the user. Preferably, RH0 is 30%-70%. When RH0 ≤ RH, it indicates that the indoor air humidity meets the current comfort requirements, and the air conditioner does not need to humidify and can directly operate in the consumer-set mode normally. Particularly, when it is determined that humidification is not required but the humidification instruction comes from the user, methods such as voice push, panel display, and mobile phone push are needed to prompt the user that the current humidity is appropriate and humidification is not required, to avoid the user doubting the normal operation of the air conditioner function. When RH < RH0, it indicates that the indoor air humidity is low, and the humidification mode needs to be run to increase the humidity and ensure the comfort of the indoor environment. The air conditioner continues to run the next step, that is, step 4.

[0175] In the solution of the present invention, according to the indoor environment parameters of the air conditioner and / or the user instructions of the air conditioner, it is determined whether to run the humidification mode of the air conditioner. If the humidification mode needs to be run, the priority of running the humidification mode and the air conditioning mode is determined in combination with the indoor and outdoor environment parameters, and different humidification parameters are run in different modes to ensure the simultaneous comfort of the user's temperature and humidity.

[0176] In some embodiments, the indoor environment parameters of the air conditioner include: the indoor environment temperature of the air conditioner and the indoor environment relative humidity of the air conditioner.

[0177] The control unit 104 determines the target humidification amount of the air conditioner and the priority mode between the humidification mode and the heat exchange mode of the air conditioner according to the indoor environment parameters of the air conditioner, including:

[0178] The control unit 104 is specifically further configured to determine the target moisture content of the air conditioner according to the target temperature and the target humidity of the air conditioner. For specific details, reference can be made to the relevant description of formula (1); wherein, the target temperature of the air conditioner is the target temperature T0 (i.e., the user-set temperature), the target humidity of the air conditioner is the target humidity RH0 (i.e., the optimal comfort humidity), and the target moisture content of the air conditioner is δ(T0, RH0). For the specific functions and processing of this control unit 104, reference is also made to step S310.

[0179] The control unit 104 is further configured to determine the actual moisture content of the air conditioner based on the indoor ambient temperature of the air conditioner and the indoor relative humidity of the air conditioner. For details, see the relevant description of formula (1); wherein the indoor ambient temperature of the air conditioner is such as the current temperature T of the environment in which the air conditioner is located, the indoor relative humidity of the air conditioner is such as the relative humidity RH of the environment in which the air conditioner is located, and the actual moisture content of the air conditioner is such as δ(T, RH). The specific functions and processing of the control unit 104 are also described in step S320.

[0180] The control unit 104 is further configured to determine a difference between the target humidity level of the air conditioner and the actual humidity level of the air conditioner, which is recorded as a target humidification level of the air conditioner; the target humidification level of the air conditioner is exemplified by the target humidification level M. The specific functions and processing of the control unit 104 are further described in step S330.

[0181] The control unit 104 is further configured to determine a priority mode between the humidification mode and the heat exchange mode of the air conditioner according to the target humidification amount of the air conditioner. The specific functions and processing of the control unit 104 are also shown in step S340.

[0182] like Figure 10 As shown, a humidification control method for a humidification air conditioner (ie, a waterless humidification air conditioner) further includes: step 4, controlling the air conditioner to operate in a humidification mode, specifically including steps 41 and 42.

[0183] Step 41 : Determine the humidification mode and target humidification amount based on the indoor environmental parameters, and then execute step 42 .

[0184] Specifically, the indoor temperature and humidity detection device is controlled to obtain the current temperature T of the environment where the air conditioner is located, and determines the target humidification amount M in combination with the target temperature T0 (ie, the user-set temperature) and the target humidity RH0 (ie, the optimal comfort humidity).

[0185] It is easy for people in this field to understand that there is a certain corresponding relationship between air temperature, relative humidity and moisture content, which can be characterized and queried through the psychrometric diagram. In other words, knowing two of the parameters can be used to query and calculate the other parameter, that is, the air moisture content δ under current conditions can be calculated through temperature and relative humidity. Then, the target humidification amount M can be determined by combining the difference in moisture content before and after:

[0186] M=δ(T0,RH0)-δ(T,RH) (1).

[0187] The humidification mode can be further determined in combination with the size of the target humidification amount M.

[0188] In the solution of the present invention, the air conditioner can determine the priority of operating the humidification mode and the air conditioning mode in combination with indoor and outdoor environmental parameters, and operate different humidification parameters in different modes to ensure the user's simultaneous comfort in temperature and humidity.

[0189] In some embodiments, the control unit 104 determines a priority mode between the humidification mode and the heat exchange mode of the air conditioner according to the target humidification amount of the air conditioner, including:

[0190] The control unit 104 is further configured to determine whether the target humidification amount of the air conditioner is less than or equal to a preset humidification amount threshold; wherein the preset humidification amount threshold is, for example, a humidification mode determination threshold M0. The specific functions and processing of the control unit 104 are also referred to in step S410.

[0191] The control unit 104 is further configured to, if it is determined that the target humidification amount of the air conditioner is less than or equal to a preset humidification amount threshold, determine that the heat exchange mode of the air conditioner is a priority mode, thereby giving priority to operating the heat exchange mode of the air conditioner. Specifically, when the heat exchange mode of the air conditioner is given priority, the humidification mode of the air conditioner is simultaneously operated. The specific functions and processing of the control unit 104 are further described in step S420.

[0192] The control unit 104 is further configured to, if it is determined that the target humidification amount of the air conditioner is greater than a preset humidification amount threshold, determine that the humidification mode of the air conditioner is a priority mode, thereby giving priority to operating the humidification mode of the air conditioner. Specifically, while giving priority to operating the humidification mode of the air conditioner, the heat exchange mode of the air conditioner is also operated. The specific functions and processing of the control unit 104 are further described in step S430.

[0193] like Figure 10As shown, a humidification control method for a humidifying air conditioner (i.e., a waterless humidifying air conditioner) further includes: in step 41, the humidification mode can be further determined based on the target humidification amount M. Air temperature, relative humidity, moisture content, etc. have a corresponding relationship and can be mathematically calculated equivalently or presented in a single diagram, called a psychrometric diagram. Two of these parameters can be used to determine the other parameter. Specifically, M0 is defined as the humidification mode determination threshold. When M ≤ M0, the current environmental parameters are not significantly different from the optimal comfort parameters. The air conditioner can prioritize the air conditioner mode (temperature control) and simultaneously operate the humidification mode (humidity control). When M > M0, the current environmental parameters are significantly different from the optimal comfort parameters. The humidification mode should be prioritized to meet comfort requirements before considering temperature control requirements. Humidity entering the room during humidification is condensed and absorbed by the fins of the air conditioner heat exchanger (i.e., the indoor heat exchanger), resulting in a decrease in humidification efficiency. This means that humidification and cooling conflict, requiring a choice between the two depending on the situation. Based on this, when the calculated target humidification amount M is low, that is, the current environmental parameters are not much different from the comfort level, the air conditioner mode can be used as the main mode and humidification can be performed simultaneously. If the calculated target humidification amount M is large, that is, the current environment is very dry and uncomfortable, the humidification mode needs to be prioritized at this time, that is, the air conditioner cooling parameters need to be controlled so that it does not cause condensation loss and other problems during humidification, affecting the humidification effect.

[0194] In some embodiments, the priority mode between the humidification mode of the air conditioner and the heat exchange mode of the air conditioner includes: the heat exchange mode of the air conditioner is the priority mode, or the humidification mode of the air conditioner is the priority mode; the outdoor environment parameters of the air conditioner include: the outdoor environment temperature of the air conditioner, and the outdoor environment relative humidity of the air conditioner.

[0195] The control unit 104 controls the operation of the heat exchange module and the humidification module according to the outdoor environment parameters of the air conditioner and the target humidification amount of the air conditioner in the priority mode between the humidification mode and the heat exchange mode of the air conditioner, including: determining the humidification operation parameters of the humidification module, specifically including: determining the humidification operation parameters of the humidification module when the humidification mode of the air conditioner is the priority mode, and determining the humidification operation parameters of the humidification module when the heat exchange mode of the air conditioner is the priority mode, specifically as follows:

[0196] The control unit 104 is further configured to determine the operating parameters of the humidification module according to the outdoor ambient temperature of the air conditioner and the outdoor ambient relative humidity of the air conditioner when the humidification mode of the air conditioner is the priority mode or when the heat exchange mode of the air conditioner is the priority mode. For details, please refer to the relevant description of formula (3); wherein the outdoor ambient temperature of the air conditioner is the ambient temperature T 外 , the outdoor environment relative humidity of the air conditioner is such as relative humidity RH 外 The specific functions and processing of the control unit 104 are also described in step S510.

[0197] The control unit 104 is further configured to determine the humidification capacity of the humidification module based on the operating parameters of the humidification module. For details, see the relevant description of formula (2); wherein the humidification capacity of the humidification module is such as the humidification capacity J of the humidification module. The specific functions and processing of the control unit 104 are also shown in step S520.

[0198] The control unit 104 is further configured to determine a humidification rate of the humidification module based on the outdoor ambient temperature of the air conditioner, the outdoor relative humidity of the air conditioner, and the humidification capacity of the humidification module. For details, see the relevant description of formula (3). The humidification rate of the humidification module is, for example, the moisture content k delivered to the room per unit time. The specific functions and processing of the control unit 104 are also described in step S530.

[0199] The control unit 104 is further configured to use the ratio of the target humidification amount of the air conditioner to the humidification speed of the humidification module as the operating time of the humidification module; and to use the operating parameters of the humidification module and the operating time of the humidification module as the humidification operating parameters of the humidification module. The operating time of the humidification module is, for example, the humidification module operating time t. The humidification operating parameters of the humidification module include the operating parameters of the humidification module and the operating time of the humidification module. The specific functions and processing of the control unit 104 are further described in step S540.

[0200] The control unit 104 is further configured to control the humidification module to operate according to the humidification operating parameters of the humidification module. The specific functions and processing of the control unit 104 are also shown in step S550.

[0201] like Figure 10 As shown, a humidification control method for a humidifying air conditioner (ie, a waterless humidifying air conditioner) further includes: step 42, running different humidification modes according to different needs, specifically including steps 421 and 422.

[0202] Step 421 When the humidification mode is determined to be the priority, the air conditioner is controlled to operate according to the following procedures:

[0203] In step 421, it includes: ① determining humidification operation parameters based on outdoor environmental parameters and target humidification amount.

[0204] The outdoor environmental parameter is the ambient temperature T 外 and relative humidity RH 外 The humidification operation parameters include the operation parameters of the humidification module and the humidification operation time t. The operation parameters of the humidification module include the rotation speed r of the moisture absorption fan 1. 吸 , humidification fan 4 speed r 加 , wheel 2 speed r, heating temperature T 热 .

[0205] It is easy for people in this field to understand that the ability of the moisture-absorbing wheel 2 to absorb moisture is closely related to the rotation speed of the moisture-absorbing fan 1 (i.e., wind speed, which determines the air content passing through the wheel 2. Generally, the higher the rotation speed, the more air volume passing through the wheel 2 and the greater the adsorption capacity) and the speed of the wheel 2 (which determines the contact and adsorption time between the moist air and the wheel 2. Generally, the slower the rotation speed of the moisture-absorbing fan 1, the greater the adsorption capacity of the wheel 2, but the fewer cycles per unit time, and the smaller the adsorption capacity). The ability to release moisture is closely related to the heating temperature (which determines the desorption rate of moisture from the wheel 2. Generally, the higher the temperature, the faster the desorption), the rotation speed of the humidifying fan 4 (i.e., wind speed, which determines the air content carrying moisture passing through the wheel 2. Generally, the higher the wind speed, the greater the humidification capacity) and the speed of the wheel 2 (which determines the contact time between the air and the wheel 2. Generally, the slower the rotation speed, the longer the contact time, the relatively higher the content of moist air carried, and the greater the humidification capacity). The above-mentioned ability to absorb moisture and the ability to release moisture jointly determine the humidification capacity of the humidification module. Here, the humidification capacity of the humidification module is defined as J, that is:

[0206] J=f(r 吸 ,r 加 ,r,T 热 ) (2).

[0207] Formula (2) is only an explanation of the humidification capacity control relationship. If necessary, the functional relationship can be refined in combination with test data. Taking into account some special situations, such as avoiding condensation caused by excessive humidification, it is necessary to reasonably control the humidification capacity. Therefore, optionally, the humidification capacity of the humidification module can be controlled by adjusting any of the above parameters, and there is a certain equivalence between the above parameters. For example, increasing the heating temperature is equivalent to increasing the speed of the humidification fan 4. The specific adjustment and control can be carried out according to needs and actual conditions. Of course, under normal circumstances, it is hoped that the humidification is as fast as possible. Therefore, preferably, the operating parameters of the humidification module are the optimal constants (i.e., r 吸 ,r 加 ,r,T 热, J are fixed values). At this point, the humidification module can maximize its humidification capacity and meet the user's humidification needs as quickly as possible. The above optimal fixed values ​​can be obtained through experiments or theoretical calculations.

[0208] In addition, outdoor environmental parameters (i.e. temperature and relative humidity, which together determine the moisture content of the air. Generally, the higher the moisture content, the easier the adsorption and the greater the adsorption amount. At the same time, temperature also affects the adsorption rate. Contrary to desorption, the higher the temperature, the more difficult the adsorption) will also affect the humidification effect of the humidification module.

[0209] In summary, the humidification capacity of the humidification module and the outdoor environmental parameters jointly determine the speed (or effect) of the humidification module on the indoor humidification. Here, k (the moisture content delivered to the room per unit time) is used to characterize it, that is:

[0210] k=f(T 外 , RH 外 , r 吸 , r 加 , r, T 热 )=f(T 外 , RH 外 , J) (3).

[0211] In particular, when J is a constant, the humidification speed k is only related to the outdoor environmental parameters. That is, for different outdoor environmental conditions, the humidification module has different humidification speeds. Formula (3) only illustrates the influence of the humidification speed. If necessary, the functional relationship can be refined by combining test data.

[0212] Furthermore, combined with the target humidification amount, the humidification module operating time t can be obtained as:

[0213] t=M / k (4).

[0214] Therefore, the humidification speed of the humidification module can be determined by the outdoor environmental parameters, and the humidification operation time can be further determined by combining the target humidification amount. The target humidification amount divided by the humidification speed k equals the time t required to reach the target humidification amount.

[0215] In the solution of the present invention, the air conditioner can determine the priority of operating the humidification mode and the air-conditioning mode based on indoor and outdoor environmental parameters, and operate different humidification parameters in different modes to ensure the user's simultaneous comfort of temperature and humidity. Thus, it solves the problem that the humidification solution in the relevant solution does not consider the conflict between humidification and cooling, resulting in insufficient effective humidification and limited humidification effect.

[0216] In some embodiments, the humidification module includes: a moisture absorption fan 1, a humidification fan 4, a rotor 2, and a heating device 3; a humidification pipe, such as a humidification pipe 5, is provided in the indoor unit; the operating parameters of the humidification mode include at least one of the following: the speed of the moisture absorption fan 1, the speed of the humidification fan 4, the speed of the rotor 2, and the heating temperature of the heating device 3, such as the speed of the moisture absorption fan 1 r 吸 , humidification fan 4 speed r 加 , wheel 2 speed r, heating temperature T 热 .

[0217] like Figure 9 As shown, the humidification module includes a dehumidifying fan 1, a humidifying fan 4, a rotor 2, and a heating device 3. The dehumidifying fan 1 is used to draw humid outdoor air into the rotor 2, where it absorbs moisture and becomes dry air, which is then discharged outdoors. The rotor 2 is made by loading a hygroscopic material such as zeolite molecular sieve or metal-organic framework (MOF) onto the surface of a porous honeycomb carrier material such as glass fiber or ceramic fiber. It absorbs moisture from the air in an adsorption zone and then rotates to a desorption zone where it releases the absorbed moisture under high-temperature airflow. The heating device 3 is a positive temperature coefficient (PTC) or infrared heater that heats the rotor 2 (or air) to a high temperature, enabling moisture desorption from the rotor 2. The humidifying fan 4 is used to pass outdoor air through the heating device 3 and rotor 2, carrying the humidified air into the room. The indoor unit includes a humidification duct (such as the humidification tube 5), the outlet of which is located above the evaporator 6. The outdoor wet air enters the room through the humidification pipe, passes through the air outlet, and is temperature-controlled by the heat exchanger (such as the evaporator 6) before being sent to the indoor space to achieve humidification. The humidification module is equipped with a temperature and humidity sensor for detecting the outdoor ambient temperature and humidity, including a temperature sensor, a humidity sensor, or a temperature and humidity sensor.

For details, see the relevant description of formula (5). The specific functions and processing of the control unit 104 are also described in step S610.

[0222] The control unit 104 is further configured to determine the relative humidity of the outlet air of the humidification pipe according to the outlet air temperature of the humidification pipe and the humidification speed of the humidification module in the humidification operation parameter of the humidification module, specifically referring to the relevant description of formula (6); wherein the outlet air temperature of the humidification pipe is such as the outlet moisture temperature T of the humidification pipe 5 湿 The relative humidity of the outlet air of the humidification pipe is such as the relative humidity RH of the outlet of humidification pipe 5 湿 The specific functions and processing of the control unit 104 are also described in step S620.

[0223] The control unit 104 is further configured to determine the outlet dew point temperature of the humidification pipe according to the outlet air temperature of the humidification pipe and the relative humidity of the outlet air of the humidification pipe. For details, please refer to the relevant description of formula (7); wherein the outlet dew point temperature of the humidification pipe is such as the dew point temperature T 露 The specific functions and processing of the control unit 104 are also described in step S630.

[0224] The control unit 104 is further configured to adjust the heat exchange operating parameters of the heat exchange module so that during the operation time of the humidification module, the pipe temperature of the indoor heat exchanger in the heat exchange module is greater than the outlet dew point temperature of the humidification pipe. The heat exchange operating parameters of the heat exchange module include the compressor frequency, the speed of the indoor fan 7, etc. The pipe temperature of the indoor heat exchanger is such as the pipe temperature T 管 The specific functions and processing of the control unit 104 are also described in step S640.

[0225] like Figure 10 As shown, a humidification control method for a humidification air conditioner (ie, a waterless humidification air conditioner) further includes: in step 421, it also includes: ② adjusting the operating parameters of the air conditioner based on the humidification operating parameters.

[0226] The operating parameters of the air conditioner are mainly the temperature of the air conditioner pipe T 管 , detected by the system's own temperature sensing package.

[0227] Specifically, the air conditioner is controlled to determine the outlet temperature of the humidifying pipe 5 T according to the humidification operation parameters. 湿 and relative humidity RH 湿 , the humidity temperature T 湿 and outer ring temperature T 外 and heating temperature T 热 Relevant, namely:

[0228] T 湿 =f(T 外 , T 热 ) (5).

[0229] Formula (5) is only an explanation of the relationship between humidity and temperature. Humidity comes from the outside and enters the room after being heated and absorbed by the wheel 2. Therefore, the humidity temperature is related to the external ring temperature and the heating temperature. 湿 It is related to the humidification speed k, that is:

[0230] RH 湿 =f(T 湿 , k) (6).

[0231] Formula (6) is only for explaining the relationship. As mentioned above, relative humidity is related to temperature and moisture content, and moisture content is related to the humidification speed, that is, the amount of moisture delivered into the room.

[0232] Optionally, the above parameters can also be directly detected and obtained by directly setting a temperature and humidity detection device at the outlet of the humidification tube 5.

[0233] Furthermore, combined with the outlet temperature T of the humidifying tube 5, 湿 and relative humidity RH 湿 The dew point temperature T at this time can be determined 露 ,Right now:

[0234] T 露 =f(T 湿 , RH 湿 ) (7).

[0235] There is a corresponding relationship between air temperature, relative humidity, and moisture content, which can be calculated mathematically or plotted on a graph called a psychrometric diagram. Through the temperature curve and relative humidity curve on this graph, we can also obtain the dew point temperature under these conditions (when the relative humidity is 100%). When the temperature is lower than this dew point temperature, condensation will occur.

[0236] Since humidification is the priority at this time, in order to ensure that moisture is not condensed and collected by the heat exchanger, it is necessary to control the temperature T of the air conditioner inner tube. 管 During the humidification operation time tT 管 >T 露 , that is, T 管 >T露 The air conditioner is regulated and controlled by controlling system parameters such as compressor frequency and indoor fan speed.

[0237] In the solution of the present invention, the operating parameters of the air conditioner are adjusted based on the humidification operating parameters, with humidification being given priority, thereby ensuring that moisture is not condensed and collected by the heat exchanger, thereby improving the effect of priority humidification.

[0238] In some embodiments, the control unit 104 controls the operation of the heat exchange module and the humidification module according to the outdoor environment parameters of the air conditioner and the target humidification amount of the air conditioner in a priority mode between the humidification mode and the heat exchange mode of the air conditioner, and further includes: adjusting the humidification operation parameters of the humidification module based on the heat exchange operation parameters of the heat exchange module when the heat exchange mode of the air conditioner is the priority mode, specifically as follows:

[0239] The control unit 104 is further configured to adjust the humidification operating parameters of the humidification module based on the heat exchange operating parameters of the heat exchange module after controlling the humidification module to operate according to the humidification operating parameters of the humidification module when the heat exchange mode of the air conditioner is the priority mode.

[0240] The control unit 104 adjusts the humidification operating parameters of the humidification module based on the heat exchange operating parameters of the heat exchange module, including:

[0241] The control unit 104 is further configured to determine the outlet air temperature of the humidification pipe based on the outdoor ambient temperature of the air conditioner and the heating temperature of the heating device 3 in the humidification operating parameters of the humidification module. For details, see the relevant description of formula (5). The specific functions and processing of the control unit 104 are also described in step S710.

[0242] The control unit 104 is further configured to determine the relative humidity of the outlet air of the humidification pipe according to the outlet air temperature of the humidification pipe and the humidification speed of the humidification module in the humidification operation parameter of the humidification module, specifically referring to the relevant description of formula (6); wherein the outlet air temperature of the humidification pipe is such as the outlet moisture temperature T of the humidification pipe 5 湿 The relative humidity of the outlet air of the humidification pipe is such as the relative humidity RH of the outlet of humidification pipe 5 湿 The specific functions and processing of the control unit 104 are also described in step S720.

[0243] The control unit 104 is further configured to determine the outlet dew point temperature of the humidifying pipe according to the outlet air temperature of the humidifying pipe and the outlet air relative humidity of the humidifying pipe, for details, see the relevant description of formula (7); and determine the outlet air moisture content of the humidifying pipe according to the outlet air temperature of the humidifying pipe and the outlet air relative humidity of the humidifying pipe, for details, see the relevant description of formula (1); wherein the outlet dew point temperature of the humidifying pipe is such as the dew point temperature T 露 The outlet air humidity of the humidification pipe is such as the real-time air humidity δ 湿 The specific functions and processing of the control unit 104 are also described in step S730.

[0244] The control unit 104 is further configured to determine the humidification loss of the heat exchange module based on the moisture content of the outlet air of the humidification pipe, the time period during which the pipe temperature of the indoor heat exchanger in the heat exchange module is less than or equal to the outlet dew point temperature of the humidification pipe, and the difference between the outlet dew point temperature of the humidification pipe and the pipe temperature of the indoor heat exchanger in the heat exchange module. For details, please refer to the relevant description of formula (8); wherein the pipe temperature of the indoor heat exchanger is such as the pipe temperature T 管 The time period during which the pipe temperature of the indoor heat exchanger in the heat exchange module is less than or equal to the outlet dew point temperature of the humidification pipe is T 管 ≤T 露 The time period t', the difference between the outlet dew point temperature of the humidification pipe and the pipe temperature of the indoor heat exchanger in the heat exchange module is the difference between the pipe temperature and the dew point temperature T 露 -T 管 The loss humidification capacity of the heat exchange module is such as the loss humidification capacity M 损 The specific functions and processing of the control unit 104 are also described in step S740.

[0245] The control unit 104 is further configured to use the ratio of the humidification loss of the heat exchange module to the humidification speed of the humidification module as the humidification operation extension time of the humidification module; and the sum of the operation time of the humidification module and the humidification operation extension time of the humidification module as the new operation time of the humidification module. 延 =M 损 / k, the new running time of the humidification module is t+t, the actual running time of the air conditioner humidification is 延 The specific functions and processing of the control unit 104 are also described in step S750.

[0246] like Figure 10 As shown, a humidification control method for a humidification air conditioner (ie, a waterless humidification air conditioner) further includes: step 422, When the air conditioner mode is determined to be the priority, the air conditioner is controlled to operate according to the following procedures:

[0247] ① Determine the humidification operation parameters based on the outdoor environmental parameters and the target humidification amount.

[0248] Specifically, in combination with the above, the humidification capacity of the humidification module and the outdoor environmental parameters jointly determine the indoor humidification speed k of the humidification module, that is:

[0249] k=f(T 外 , RH 外 , r 吸 , r 加 , r, T 热 )=f(T 外 , RH 外 , J) (3).

[0250] Further combined with the target humidification amount M, the theoretical operating time t of the humidification module can be obtained:

[0251] t=M / k (4).

[0252] ② Adjust the humidification operating parameters based on the operating parameters of the air conditioner.

[0253] The operating parameters of the air conditioner are mainly the temperature of the air conditioner pipe T 管 .

[0254] Specifically, in combination with the above, the air conditioner can be controlled to determine the outlet temperature of the humidifying pipe 5 T by combining the humidification operation parameters. 湿 and relative humidity RH 湿 , and thus determine the dew point temperature T 露 and the air humidity δ under current conditions 湿 , see formula (5), formula (6), formula (7) and formula (1) for details.

[0255] Since the air conditioner is prioritized at this time, the pipe temperature in the air conditioner may be less than or equal to the dew point temperature of the humidified air within a certain time period t', that is, T 管 ≤T 露 At this point, the moisture delivered by the humidification tube 5 will be partially condensed and collected, resulting in the actual humidification rate being lower than the target rate. To achieve the target humidification effect, it is necessary to adjust the humidification operating parameters, such as extending the humidification time or increasing the humidification speed. Since the humidification module is generally operating at its maximum capacity, and the various parameters of the humidification module affect each other, making adjustment difficult, the preferred correction method is to extend the humidification time.

[0256] Here we define the loss of humidification as M 损 , then the loss of humidification capacity M 损 and temperature difference (i.e. the difference between pipe temperature and dew point temperature T露 -T 管 ), real-time air humidity δ 湿 and T 管 ≤T 露 The time period t' is related to

[0257] M 损 =f(δ 湿 ,t',T 露 -T 管 ) (8).

[0258] It is easy to understand that compared with the indoor environment, the outdoor environment is open and infinite, so its environmental parameters will not change much, and the operating parameters of the humidification module are generally fixed. Therefore, when the outdoor environment is determined, its humidification speed is also fixed, that is, T 露 , δ 湿 are all constant values. However, the pipe temperature changes continuously as the air conditioner runs, and becomes larger and larger, that is, T 露 -T 管 As the difference in temperature decreases, the amount of condensed water decreases. Therefore, the above process calculates the total amount of condensed water under different pipe temperature conditions during time t'. Due to the air conditioner mode priority, there are periods of time when the pipe temperature falls below the dew point, during which condensation occurs. The amount of condensation depends on the temperature difference and the humidity content at that time. The total amount of condensation during the entire time period when the pipe temperature falls below the dew point is the total humidification loss.

[0259] Further combined with the loss of humidification capacity M 损 (i.e. the second target humidification amount) can be obtained by extending the humidification operation time t 延 for:

[0260] t 延 =M 损 / k (9).

[0261] Since T 管 >T 露 Therefore, there is no attenuation problem during humidification over an extended period of time. Humidification capacity M 损 Divided by the humidification speed k equals the time t required to reach the humidification amount 延 .

[0262] In short, based on the air conditioner operating internal pipe temperature T 管 The actual humidification operation time of the air conditioner can be determined as t+t 延 .

[0263] Based on steps 421 and 422, the humidification module is controlled to operate according to the corresponding mode and parameters. The air conditioner is controlled to operate according to the corresponding mode and parameters. Specifically, the air conditioner is controlled to determine whether to operate the humidification mode based on user instructions or real-time monitoring of environmental parameters. When humidification is determined to be necessary, the air conditioner determines the humidification amount and whether to prioritize humidification or air conditioning based on the environmental parameters. The humidification module is then controlled to operate according to the corresponding mode and parameters to ensure the user's temperature and humidity are both comfortable.
