[0034] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0036] The operating principle of the air conditioner involved in the embodiment of the present application is described in detail below:

[0037] like Figure 1As shown in the figure, the compressor compresses the refrigerant (coolant) and transports it to the condenser through a pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is depressurized by a capillary tube (throttling unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator to evaporate from liquid to gas, and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature and low-pressure gaseous refrigerant in the evaporator is transported to the compressor to participate in the next cycle.

[0038] Based on the above working principle, the working principle of the air conditioner in different working modes includes:

[0039] 1. Refrigeration cycle (including dehumidification cycle) or heating cycle: The air conditioner achieves cooling or heating of air through the refrigeration cycle or heating cycle of the outdoor unit. In the refrigeration cycle, the outdoor unit compresses the refrigerant into high-temperature and high-pressure gas through the compressor, and then releases heat through the condenser to turn the refrigerant into high-temperature and high-pressure liquid, and then expands the refrigerant into low-temperature and low-pressure liquid through the expansion valve, absorbing the heat of the indoor air and making the indoor air cool. In the heating cycle, the outdoor unit works in reverse to release the heat of the refrigerant into the room, thereby achieving heating.

[0040] 2. Indoor unit air supply and return: The air conditioner sends hot and cold air into the duct system through the indoor unit, and then transports it to different rooms or areas through the duct system. The indoor unit is usually equipped with a fan and a heat exchanger, which can send the hot and cold air sent from the outdoor unit into the duct system through the fan, and then transport it to different rooms or areas through the duct. The indoor unit will also absorb indoor air and exchange heat with the refrigerant to achieve indoor air cooling or heating. 3. Duct system: The air conditioner transports hot and cold air to different rooms or areas through the duct system. The duct system generally includes a supply channel and a return channel. The supply channel sends hot and cold air from the indoor unit to different rooms or areas, and the return channel sends the air in the room back to the indoor unit through the return air port for further processing. 4. Humidity and wind speed control: The air conditioner is usually equipped with a humidity sensor and a wind speed controller. It can control the humidity and wind speed of different rooms or areas by controlling the operation of the outdoor unit and the indoor unit according to the humidity and wind speed requirements set by the user. Generally speaking, air conditioners can achieve independent humidity control in different rooms or areas to provide a comfortable indoor environment.

[0041] In response to the technical problem in the related art that the energy consumption of turning on the fresh air function when the air conditioner is in dehumidification mode is too high, the embodiment of the present application proposes that a suitable time can be selected to turn on the fresh air function of the air conditioner, which can not only reduce the energy consumption of the air conditioner, but also exchange indoor and outdoor air to improve indoor air quality.

[0042] The fresh air control method in the dehumidification mode provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in combination with the accompanying drawings.

[0043] like Figure 2 As shown, an embodiment of the present application provides a method for controlling fresh air in a dehumidification mode, and the method may include the following steps 201 to 203:

[0044] Step 201: When the working mode of the air conditioner is a dehumidification mode, obtain humidity parameter information.

[0045] The humidity parameter information includes: indoor environment humidity, outdoor environment humidity and set humidity of the air conditioner.

[0046] For example, before determining whether the fresh air function of the air conditioner can be turned on, it is first necessary to determine the indoor humidity, outdoor humidity and the set humidity of the air conditioner in the dehumidification mode of the current environment. After that, it is determined whether the fresh air function of the air conditioner can be turned on based on the indoor humidity, outdoor humidity and the set humidity of the air conditioner.

[0047] Step 202: determine whether the fresh air function needs to be turned on according to the humidity parameter information, and if it is determined that the fresh air function needs to be turned on, turn on the fresh air function, and adjust the operating parameters of the air conditioner based on the humidity parameter information.

[0048] The adjustment of the operating parameters of the air conditioner is used to ensure that the operating effect of the air conditioner remains consistent with that before the adjustment.

[0049] Specifically, the above step 202 may include the following steps 202a:

[0050] Step 202a: when the indoor environmental humidity does not reach the set humidity, compare the outdoor environmental humidity and the indoor environmental humidity, and determine whether the fresh air function needs to be turned on based on the comparison result.

[0051] It is understandable that when the air conditioner is in the dehumidification mode and the indoor humidity has reached the set humidity of the air conditioner, if the fresh air function of the air conditioner is turned on at this time, it may cause a significant change in the indoor humidity, causing the compressor to restart, thereby increasing the energy consumption of the air conditioner. Based on this, the fresh air control method in the dehumidification mode provided in the embodiment of the present application first needs to determine whether the indoor humidity has reached the set humidity of the air conditioner before determining whether the fresh air function needs to be turned on. If not, it can be further determined whether the fresh air function needs to be turned on.

[0052] It should be noted that in the embodiment of the present application, the judgment criterion for turning on the fresh air function is: whether it will increase the energy consumption of the air conditioner. If so, the fresh air function will not be actively turned on. If not, turning on the fresh air function can not only improve the indoor air quality, but also reduce the energy consumption of the air conditioner to a certain extent.

[0053] Specifically, in the case where the outdoor environment humidity is lower than the indoor environment humidity, the above step 202a may include the following steps 202a1:

[0054] Step 202a1: when the outdoor environment humidity is lower than the indoor environment humidity and a first humidity difference between the outdoor environment humidity and the indoor environment humidity is lower than a first preset humidity difference, determine to turn on the fresh air function.

[0055] For example, when the outdoor ambient humidity is lower than the indoor ambient humidity, the fresh air system of the air conditioner may be turned on to reduce the indoor ambient humidity.

[0056] For example, when the air conditioner is in dehumidification mode, if the outdoor humidity is lower than the indoor humidity, the fresh air function of the air conditioner can be turned on to introduce outdoor air into the room to reduce the indoor humidity. In this way, the indoor air quality can be improved and the energy consumption of the air conditioner can be reduced.

[0057] It is understandable that the air conditioner is usually turned on in dehumidification mode in the hot summer to reduce the indoor humidity, but at night when the outdoor air is cooler and the humidity is lower, the fresh air function of the air conditioner can be turned on. After turning on the fresh air function of the air conditioner, it can not only quickly reduce the indoor humidity and indoor air quality, but also greatly reduce the energy consumption of the air conditioner.

[0058] Specifically, in the case where the outdoor environment humidity is greater than the indoor environment humidity, the above step 202a may further include the following step 202a2:

[0059] Step 202a2: when the outdoor environment humidity is greater than the indoor environment humidity and a first humidity difference between the outdoor environment humidity and the indoor environment humidity is less than a second preset humidity difference, determine to turn on the fresh air function.

[0060] For example, when the outdoor humidity is greater than the indoor humidity, the fresh air function of the air conditioner can also be turned on, but a semiconductor refrigeration device installed in the fresh air duct is required to reduce the air humidity input to the indoor environment.

[0061] For example, after determining to turn on the fresh air function of the air conditioner, in order to ensure that the operating effect of the air conditioner remains consistent with before the operating parameters are adjusted, the operating parameters of the air conditioner also need to be adjusted to avoid rapid changes in indoor environmental humidity, while also reducing the energy consumption of the air conditioner.

[0062] Specifically, based on the above step 202a2, the step of starting the fresh air function in the above step 202 may include the following step 202b:

[0063] Step 202b, controlling the air conditioner to start the fresh air function, and controlling the semiconductor refrigeration device in the fresh air duct of the air conditioner to start auxiliary refrigeration, so as to reduce the humidity of the air input into the indoor environment through the fresh air duct.

[0064] Illustratively, the air conditioner in the embodiment of the present application has a semiconductor refrigeration device provided on the inner wall of the fresh air duct, which can achieve cooling with lower power consumption. Air with higher humidity will produce condensed water on its surface after passing through the semiconductor refrigeration device. In this way, the humidity of the air input into the indoor environment can be reduced to a certain extent.

[0065] Specifically, after determining that the fresh air function can be turned on, the above step 202 may include the following steps 202c1 to 202c3:

[0066] Step 202c1, calculating a second humidity difference between the outdoor ambient humidity and the indoor ambient humidity.

[0067] Step 202c2: determine a first additional adjustment ratio based on the second humidity difference, and determine the sum of the basic adjustment ratio and the first additional adjustment ratio as the first target adjustment ratio of the fresh air fan operating parameters.

[0068] Step 202c3: Adjust the operating parameters of the air conditioner based on the first target adjustment ratio.

[0069] Among them, the first additional adjustment ratio is positively correlated with the second humidity difference; and the first target adjustment ratio is used to reduce various operating parameters of the air conditioner.

[0070] Exemplarily, in an embodiment of the present application, after it is determined to turn on the fresh air function, an additional adjustment ratio can be determined based on the basic adjustment ratio and the difference between the outdoor ambient humidity and the indoor ambient humidity, and then the basic adjustment ratio is added to the additional adjustment ratio to obtain the first target adjustment ratio.

[0071] It is understandable that after turning on the fresh air function, the operating parameters of the air conditioner can be appropriately reduced to reduce the energy consumption of the air conditioner. Specifically, the first target adjustment ratio can change with the change of the indoor and outdoor environmental humidity difference, that is, when the indoor and outdoor environmental humidity difference decreases, the low target adjustment ratio will also decrease.

[0072] In a possible implementation, after the fresh air function of the air conditioner is turned on, if the outdoor environment humidity is higher than the outdoor environment humidity, the fresh air function of the air conditioner needs to be turned off to avoid increasing the energy consumption of the air conditioner.

[0073] Specifically, after the above steps 202a2 and 202a4, the fresh air control method in the dehumidification mode provided in the embodiment of the present application may further include the following step 203:

[0074] Step 203: After the air conditioner turns on the fresh air function, if the indoor ambient humidity of the current environment is greater than the outdoor ambient humidity of the current environment, and a first humidity difference between the outdoor ambient humidity and the indoor ambient humidity is greater than or equal to the second preset humidity difference, turn off the fresh air function.

[0075] Specifically, after the above step 202c2, the fresh air control method in the dehumidification mode provided in the embodiment of the present application may further include the following step 204:

[0076] Step 204: after the air conditioner turns on the fresh air function, if the difference between the current indoor humidity and the current outdoor humidity is greater than the preset temperature difference threshold, the fresh air function is turned off.

[0077] For example, in order to fully purify the indoor air, when it is determined that the fresh air function needs to be turned off, a delayed shutdown can be set, that is, when the shutdown conditions are met, the fresh air function of the air conditioner can be turned off after a preset time.

[0078] Optionally, in an embodiment of the present application, if the user forcibly turns on the fresh air function of the air conditioner through manual control without satisfying the requirements for turning on the fresh air function, the operating parameters of the air conditioner need to be adjusted in order to ensure the consistency of the operating effect of the air conditioner.

[0079] Exemplarily, after the above step 202, the fresh air control method in the dehumidification mode provided in the embodiment of the present application may further include the following steps 205 to 207:

[0080] Step 205: When it is determined that the fresh air function is not to be turned on, if a fresh air function turn-on instruction for turning on the fresh air function is received, a third humidity difference between the outdoor ambient humidity and the indoor ambient humidity is calculated.

[0081] Step 206: determine a second additional adjustment ratio based on the third humidity difference, and determine the sum of the basic adjustment ratio and the second additional adjustment ratio as the second target adjustment ratio of the fresh air fan operating parameter.

[0082] Step 207: Adjust the operating parameters of the air conditioner based on the second target adjustment ratio.

[0083] The second additional adjustment ratio is positively correlated with the third humidity difference; and the second target adjustment ratio is used to improve various operating parameters of the air conditioner.

[0084] It is understandable that, if the user feels that the indoor air quality is poor and forcibly turns on the fresh air function after determining not to turn on the fresh air function, it is necessary to increase the compressor operating frequency of the air conditioner and / or the fan speed, etc. to improve the dehumidification effect, so as to avoid a greater impact on the indoor environmental humidity after turning on the fresh air function.

[0085] Optionally, in an embodiment of the present application, when the air conditioner is just turned on, the operation of the air conditioner can be controlled in combination with the operating parameters of other air conditioners in the current area to realize the automation of the operation of the air conditioner, eliminating the step of manual setting by the user.

[0086] Exemplarily, before the above step 201, the fresh air control method in the dehumidification mode provided in the embodiment of the present application may further include the following steps 208 to 210:

[0087] Step 208: When a power-on instruction is received, obtain user information of the air conditioner and user information of a first air conditioner with the same performance parameters as the air conditioner in the area to which the air conditioner belongs.

[0088] It should be noted that, since air conditioners with different performance parameters have greatly different effects under the same operating parameters, the operating parameters of air conditioners with different performance parameters are of no reference significance and need to be excluded.

[0089] Step 209: Based on the user information of the air conditioner and the user information of the first air conditioner, a second air conditioner having the same user age group as the air conditioner is selected from the first air conditioner.

[0090] For example, in the implementation of this application, users can be divided according to age groups, for example, children under 6 years old, teenagers under 14 years old, young people under 30 years old, etc. The user's age can be obtained by the age set by the user when using the air conditioner, or by comprehensive judgment based on the user's height, gender, breathing rate, heart rate, body movements, and activity level detected by millimeter wave radar.

[0091] Step 210: taking an average value of the operating parameters of the third air conditioner in the second air conditioner which is in operation and in a dehumidification mode as the current operating parameters of the air conditioner.

[0092] Wherein, the first air conditioner includes a plurality of air conditioners; the operating parameters include at least one of the following: set humidity, compressor operating frequency, indoor unit fan speed, outdoor unit fan speed.

[0093] For example, after the working mode and operating parameters of the air conditioner are determined, the operation of the air conditioner can be controlled based on the working mode and operating parameters.

[0094] It is understandable that different age groups have different requirements for environmental humidity. Therefore, in order to make the operating parameters of the air conditioner more in line with the needs of users, it is necessary to screen the above-mentioned first air conditioner and select the second air conditioner for users of similar age groups.

[0095] It should be noted that the air conditioner in the embodiment of the present application can be a cabinet air conditioner, a wall-mounted air conditioner, or a duct air conditioner.

[0096] The fresh air control method in the dehumidification mode provided in the embodiment of the present application first obtains the humidity parameter information of the current environment when the air conditioner is running; then, determines whether the fresh air function needs to be turned on according to the humidity parameter information; finally, if it is determined that the fresh air function needs to be turned on, turns on the fresh air function, and adjusts the operating parameters of the air conditioner based on the humidity parameter information. In this way, the air conditioner can turn on the fresh air function at a reasonable time, and solves the technical problem of high energy consumption when the fresh air function is turned on at the same time when the air conditioner is dehumidifying in the related art.

[0097] It should be noted that the execution subject of the fresh air control method in the dehumidification mode provided in the embodiment of the present application may be a fresh air control device in the dehumidification mode, or a control module in the fresh air control device in the dehumidification mode for executing the fresh air control method in the dehumidification mode. In the embodiment of the present application, the execution of the fresh air control method in the dehumidification mode by the fresh air control device in the dehumidification mode is taken as an example to illustrate the fresh air control device in the dehumidification mode provided in the embodiment of the present application.

[0098] It should be noted that, in the embodiments of the present application, the fresh air control methods in the dehumidification mode shown in the above-mentioned method drawings are all illustrated by combining one of the drawings in the embodiments of the present application as an example. In specific implementation, the fresh air control methods in the dehumidification mode shown in the above-mentioned method drawings can also be implemented in combination with any other drawings that can be combined as shown in the above-mentioned embodiments, which will not be repeated here.
