[0055] It should be understood that the specific embodiments described herein are merely intended to explain the present application and not to limit the present application.

[0056] In order to better understand the technical solutions of the present application, the specific embodiments will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] The main solution of the embodiments of the present application is: obtaining the current running mode of the air conditioner, target setting parameters, current outdoor air parameters of the environment where the air conditioner outdoor unit is located, and current indoor air parameters of the environment where the air conditioner indoor unit is located; adjusting the communication state of the fresh air valve according to at least one of the current running mode, the target setting parameters and the current outdoor air parameters; when the fresh air valve is in an open state, switching the running mode of the air conditioner according to at least one of the current running mode, the target setting parameters, the current outdoor air parameters and the current indoor air parameters.

[0058] Due to the automatic control logic of the traditional air conditioner, the air conditioner is generally stopped when the temperature or humidity reaches the set value, and the main control means is to control the air supply speed through the temperature difference between the set temperature and the environment temperature, and only the single dimension data in the mode is considered in different modes, and the comfort of the user using the air conditioner is not involved much, and the user experience is not high.

[0059] The application provides a solution, by adjusting the fresh air valve and the operation mode of the air conditioner when the user uses the air conditioner, switching the operation mode of the air conditioner after the fresh air valve is opened, combining at least one of the current operation mode, the target set parameter, the current outdoor air parameter and the current indoor air parameter, meeting the use demand of the user, and improving the use experience of the user using the air conditioner.

[0060] Based on this, the embodiment of the application provides a control method of an air conditioner, referring to Figure 1 , Figure 1 The flowchart of the first embodiment of the control method of the air conditioner is shown in the figure.

[0061] In this embodiment, the control method of the air conditioner comprises the following steps:

[0062] Step S10: obtaining the current operation mode of the air conditioner, the target set parameter, the current outdoor air parameter of the environment where the air conditioner outdoor unit is located, and the current indoor air parameter of the environment where the air conditioner indoor unit is located.

[0063] It should be noted that the execution subject of the embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, an air conditioner, etc. capable of realizing the above functions. The control of the air conditioner is taken as an example to describe the embodiment and the following embodiments.

[0064] It should be noted that in this embodiment, the operation mode of the air conditioner includes but is not limited to the refrigeration mode, the air supply mode, the heating mode and the dehumidification mode, etc., the target set parameter refers to the target set temperature and the target set humidity set by the user, the outdoor air parameter includes but is not limited to the outdoor environment temperature and the outdoor environment humidity, etc., the indoor air parameter includes but is not limited to the indoor air temperature, the indoor air humidity, the indoor CO2 concentration, etc., and the embodiment does not make specific limitation.

[0065] Step S20: adjusting the communication state of the fresh air valve according to at least one of the current operation mode, the target set parameter and the current outdoor air parameter.

[0066] The fresh air valve is mainly used for controlling the fresh air volume of the indoor environment in the air conditioner, and can be used for adjusting the temperature, humidity and air exchange of the indoor environment. Therefore, the opening and closing state of the fresh air valve can be controlled by the corresponding relationship between the outdoor humidity and the indoor humidity, the indoor CO2 concentration, and the temperature difference between the indoor and outdoor environments, thereby improving the user experience.

[0067] Step S30: switching the operation mode of the air conditioner according to at least one of the current operation mode, the target setting parameter, the current outdoor air parameter, and the current indoor air parameter when the fresh air valve is in the open state.

[0068] In a specific implementation, if the fresh air valve is in the closed state, the air conditioner may rapidly reach the temperature stop in a single mode during automatic operation, but due to the heat exchange of the indoor environment, the air conditioner may frequently restart. In this embodiment, the air conditioner can stabilize the temperature and humidity of the indoor environment when the fresh air valve is in the open state, thereby avoiding the frequent temperature stop. On this basis, the embodiment automatically determines the corresponding mode according to the relationship between the set temperature and the environmental temperature, and controls the mutual switching between the modes, thereby improving the intelligent degree of the control of the air conditioner.

[0069] In this embodiment, the current operation mode, the target setting parameter, the current outdoor air parameter of the environment where the air conditioner outdoor unit is located, and the current indoor air parameter of the environment where the air conditioner indoor unit is located are obtained. The communication state of the fresh air valve is adjusted according to at least one of the current operation mode, the target setting parameter, and the current outdoor air parameter. When the fresh air valve is in the open state, the operation mode of the air conditioner is switched according to at least one of the current operation mode, the target setting parameter, the current outdoor air parameter, and the current indoor air parameter. When the user uses the air conditioner, the fresh air valve and the operation mode of the air conditioner are adaptively adjusted. After the fresh air valve is opened, the operation mode of the air conditioner is switched in combination with at least one of the current operation mode, the target setting parameter, the current outdoor air parameter, and the current indoor air parameter, thereby meeting the use requirements of the user, improving the use experience of the user using the air conditioner, and avoiding the technical problem that only single-dimensional data control is considered in the automatic control of the air conditioner in the prior art, and the use experience of the user is not high.

[0070] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as the above-mentioned first embodiment can be referred to the above introduction, and will not be described in detail. On this basis, please refer to Figure 2 , step S20, comprising:

[0071] Step S201: determining the concentration level corresponding to the current indoor CO2 concentration.

[0072] It can be understood that when the communication state of the fresh air valve is adjusted, the current indoor CO2 concentration corresponding concentration level can be detected first, and it is determined whether the fresh air valve needs to be opened according to the current indoor CO2 concentration corresponding concentration level. Since the indoor CO2 concentration represents the pollution level of the indoor air to some extent, the user may have difficulty breathing in the indoor environment with a high pollution level. Therefore, when the current indoor CO2 concentration corresponding concentration level is high, the fresh air valve is opened, the indoor fresh air volume is increased, the indoor CO2 concentration is reduced, and the user experience is improved.

[0073] Step S202: When the concentration level is greater than the preset level threshold, the fresh air valve is opened.

[0074] In this embodiment, the concentration level corresponding to the indoor CO2 concentration can refer to the mapping table shown in Table 1. Correspondingly, the preset level threshold can be set to 2, that is, when the concentration level corresponding to the current indoor CO2 concentration is greater than 2, or the current indoor CO2 concentration is greater than 600, the fresh air valve is opened to realize the ventilation between indoor and outdoor.

[0075] Table 1

[0076] Rank Rank Description CO2 Split Primary Excellent 0～400 Secondary Good 401～600 Tertiary Average 601～800 Quaternary Lightly soiled 801～1200 Quintenary Moderately soiled 1201～1500 Sextenary Heavily soiled Above 1500

[0077] Step S203: When the concentration level is less than or equal to the preset level threshold, the communication state of the fresh air valve is adjusted according to the current operation mode, the current outdoor environment temperature, and the target set temperature.

[0078] If the concentration level corresponding to the current indoor CO2 concentration is less than the preset level threshold, it indicates that the pollution degree of the indoor environment is small at this time, and there is no need to deliver fresh air to the indoor environment. However, considering the heat exchange and humidity exchange between indoor and outdoor environments in different operation modes, the fresh air valve communication state can be controlled in combination with the current outdoor environment temperature and the target set temperature in different modes in this embodiment.

[0079] In a possible implementation, the communication state of the fresh air valve is adjusted according to the current operation mode, the current outdoor environment temperature, and the target set temperature, including:

[0080] When the current operation mode is the cooling mode and the current outdoor environment temperature is less than the target set temperature, the fresh air valve is opened.

[0081] When the current operation mode is the heating mode and the current outdoor environment temperature is greater than the target set temperature, the fresh air valve is opened.

[0082] In the specific implementation, the air conditioner operates in cooling mode, and the current outdoor ambient temperature is lower than the target set temperature, indicating that the outdoor environment is lower than the indoor ambient temperature required by the user. In order to accelerate the cooling of the indoor environment and improve the cooling effect, the fresh air valve can be opened to deliver low-temperature fresh air to the room. If the current outdoor ambient temperature is higher than the target set temperature, the fresh air valve is closed to avoid the outdoor environment interfering with the cooling process of the indoor environment. Similarly, the air conditioner operates in heating mode, and the current outdoor ambient temperature is greater than or equal to the target set temperature, indicating that the outdoor environment is higher than the indoor ambient temperature required by the user. In order to accelerate the heating of the indoor environment and improve the heating effect, the fresh air valve can be opened to deliver high-temperature fresh air to the room. If the current outdoor ambient temperature is lower than the target set temperature, the fresh air valve is closed to avoid the outdoor environment interfering with the heating process of the indoor environment.

[0083] This embodiment reduces the degree of air pollution in the indoor environment by first determining whether the fresh air valve needs to be opened based on the indoor CO2 concentration. At the same time, different control strategies are adopted in different operating modes to accelerate the temperature control effect of the corresponding control mode, thereby improving the user experience.

[0084] refer to Figure 3 , Figure 3 FIG. 1 is a flow chart of a third embodiment of a method for controlling an air conditioner according to the present invention.

[0085] Based on the above second embodiment, a third embodiment of the present invention is proposed. In this embodiment, step S30 includes:

[0086] Step S301: When the current indoor ambient temperature is within a preset comfortable temperature range, the air conditioner is controlled to operate in an air supply mode.

[0087] It should be noted that the reference Figure 4 , Figure 4 This is a logic block diagram of the operating mode switching of this embodiment. The preset comfort temperature range refers to a temperature range with the target setting temperature set by the user as the midpoint and redundant processing performed. The redundancy value of the redundant processing is generally 1 or 2 degrees Celsius. For example: if the user sets the target setting temperature to 26 degrees Celsius, the preset comfort temperature range can be [26-1, 26+1], that is, between [25, 27], and in the air supply mode, the air supply valve of the air conditioner indoor unit is open.

[0088] In a feasible implementation manner, after controlling the air conditioner to operate in the air supply mode, the method further includes:

[0089] Calculating critical humidity based on the target humidity and a preset humidity threshold;

[0090] When the current indoor environment humidity is greater than the critical humidity and the current indoor environment temperature is less than the critical temperature, the air conditioner is controlled to run in the comfort dehumidification mode.

[0091] After running the air supply mode for a period of time, if the current indoor environment humidity is too high, there will be a problem of low temperature and high humidity, which will make the user feel stuffy in the environment of low temperature and high humidity, for example, in the plum rain season in spring, etc., affecting the user's experience. Therefore, in the embodiment, when the current indoor environment humidity is greater than the sum of the target set humidity and the preset humidity threshold, and the current indoor environment temperature is less than the critical temperature, the air conditioner is controlled to run in the comfort dehumidification mode, so as to avoid rapid temperature drop in the case of reducing indoor humidity.

[0092] It should be noted that the traditional air conditioner generally dehumidifies by running in the cooling mode, reduces the indoor environment temperature, and reduces the water saturation of the indoor environment, so that the water vapor in the air condenses to realize the dehumidification of the indoor environment. However, this process will cause the indoor temperature to drop, affecting the user's use.

[0093] Therefore, in the embodiment, on the basis of the traditional dehumidification, the target coil temperature and the target superheat of the indoor heat exchanger are corrected, and the running frequency of the compressor is adjusted based on the corrected target coil temperature, so as to avoid rapid temperature drop, and the opening degrees of the first electronic expansion valve and the second electronic expansion valve are adjusted to reduce the heat exchange of the refrigerant in the indoor heat exchanger.

[0094] And the air conditioner structure as shown in Figure 5 In the embodiment, the air conditioner indoor unit further includes a reheating coil and an indoor heat exchanger, the first electronic expansion valve is arranged between the indoor heat exchanger and the air conditioner outdoor unit, the second electronic expansion valve is arranged between the reheating coil and the air conditioner outdoor unit, and the indoor heat exchanger, the air conditioner outdoor unit and the reheating coil are connected in pairs. After the refrigerant is output from the compressor, part of the refrigerant enters the reheating coil through the high-pressure pipe, which can dry the water condensed on the subsequent evaporator, and does not need an additional electric auxiliary heating device, thereby saving energy consumption. The other part of the refrigerant flows through the outdoor heat exchanger from the outdoor unit, passes through the first electronic expansion valve and the indoor heat exchanger as an evaporator, so that the moisture in the indoor environment can be condensed on the coil of the indoor heat exchanger to realize the dehumidification of the indoor environment. Finally, the refrigerant returns to the compressor through the medium-pressure pipe.

[0095] In an available embodiment, the control of the air conditioner running in the comfort dehumidification mode includes:

[0096] calculating a temperature difference between the current indoor environment temperature and the critical temperature;

[0097] correcting the target coil temperature and the target superheat of the indoor heat exchanger according to the temperature difference;

[0098] adjust the operating frequency of the compressor according to the corrected target coil temperature;

[0099] obtain an actual superheat degree of the indoor heat exchanger, and adjust the opening degrees of the first electronic expansion valve and the second electronic expansion valve according to the corrected target superheat degree and the actual superheat degree.

[0100] In a specific implementation, with reference to Figure 6 Compared with the conventional dehumidification mode, the comfort dehumidification mode in this embodiment corrects the target coil temperature and the target superheat degree, and also corrects the minimum opening degree of the electronic expansion valve, so that the minimum opening degree of the electronic expansion valve is smaller than that of the electronic expansion valve in the conventional dehumidification mode.

[0101] In addition, when the air conditioner operates in the comfort dehumidification mode, the air conditioner in this embodiment can also start the reheating coil or the windless control, to increase the supply air temperature and reduce the supply air speed.

[0102] Further, correcting the target coil temperature and the target superheat degree of the indoor heat exchanger according to the temperature difference value includes:

[0103] querying a temperature correction value corresponding to the temperature difference value, the temperature correction value including a first correction value corresponding to the coil temperature and a second correction value corresponding to the superheat degree;

[0104] correcting the coil temperature of the indoor heat exchanger based on the first correction value, to obtain a target coil temperature;

[0105] correcting the superheat degree of the indoor heat exchanger based on the second correction value, to obtain a target superheat degree.

[0106] In a specific implementation, the lower the target coil temperature, the more cooling capacity is needed, and the compressor outputs a higher frequency; conversely, the higher the target coil temperature, the less cooling capacity is needed, and the compressor outputs a lower frequency. When determining the first correction value, when the first threshold value ≤ the temperature difference value < 0, the T2 target correction value is T2 + △t0; when the second threshold value ≤ the temperature difference value < the first threshold value, the T2 target correction value is T2 + △t1; when the third threshold value ≤ the temperature difference value < the second threshold value, the T2 target correction value is T2 + △t2; and when the temperature difference value < the third threshold value, the T2 target correction value is T2 + △t3, where the third threshold value < the second threshold value < the first threshold value < 0, and 0 < △t0 < △t1 < △t2 < △t3.

[0107] In the correction of the superheat degree of the indoor heat exchanger, the indoor unit is provided with a target superheat degree TSH, and the opening degree of the electronic expansion valve of the indoor unit is controlled. If the actual superheat degree Tsh < the target superheat degree TSH, the opening degree of the electronic expansion valve is reduced; if Tsh > TSH, the opening degree of the electronic expansion valve is increased; and if Tsh = TSH, the opening degree of the electronic expansion valve is maintained, wherein the difference between the outlet temperature T2b of the indoor heat exchanger and the middle temperature T2 of the evaporator is referred to as the actual superheat degree Tsh = T2b - T2; in determining the second correction value, when the first threshold value ≤ the temperature difference ≤ 0, the target correction value of T2 is SH_eco0; when the second threshold value ≤ the temperature difference < the first threshold value, the target correction value of T2 is SH_eco1; when the third threshold value ≤ the temperature difference < the second threshold value, the target correction value of T2 is SH_eco2; and when the temperature difference < the third threshold value, the target correction value of T2 is SH_eco3, and the parameters SH_eco0 < the parameters SH_eco1 < the parameters SH_eco2 < the parameters SH_eco3 <, which can be sequentially taken as {0, 1, 2, 3}, and the present embodiment does not make specific limitations thereon.

[0108] It should be noted that when the air conditioner runs in the comfort dehumidification mode, the second electronic expansion valve can include a fixed opening degree, so that the high-temperature refrigerant enters the evaporator after mixing with the refrigerant entering the evaporator through the reheating coil. The air is first cooled and dehumidified through the evaporator, and then heated and delivered to the indoor through the reheating coil, providing heat to the reheating coil, and the air passes through the evaporator and then passes through the reheating coil to increase the outlet air temperature.

[0109] In another possible implementation, the air conditioner indoor unit is further provided with a windless panel, and the windless panel is provided with a wind guide strip for controlling the wind direction of the air supply;

[0110] After the air conditioner runs in the comfort dehumidification mode, the method further comprises:

[0111] Adjusting the angle of the wind guide strip until the air supply wind speed of the air conditioner indoor unit is less than the preset wind speed.

[0112] In a specific implementation, if the air conditioner is provided with a windless panel, when the windless control is entered, the wind guide strip of the panel will swing to a specific angle to ensure that the panel outlet air speed is less than 0.3 m / s, so as to avoid excessive air speed affecting the user.

[0113] Step S302: controlling the air conditioner to run in a heating mode when the current indoor environment temperature is less than the minimum value of the preset comfort temperature range.

[0114] If the current indoor environment temperature is less than the minimum value of the preset comfort temperature range, it indicates that the indoor environment needs to be warmed up to meet the temperature demand of the user, and therefore the air conditioner can be controlled to run in a heating mode to increase the temperature of the indoor environment.

[0115] Step S303: when the current indoor environment temperature is greater than the maximum value of the preset comfortable temperature interval, controlling the air conditioner to run in a cooling mode.

[0116] If the current indoor environment temperature is greater than the maximum value of the preset comfortable temperature interval, it indicates that the indoor environment needs to be cooled to meet the temperature requirement of the user, and therefore the air conditioner can be controlled to run in a cooling mode to reduce the temperature of the indoor environment.

[0117] In addition, the embodiment can also control the running mode of the air conditioner in multiple dimensions in combination with the temperature, cleanliness, oxygen content and humidity of the air.

[0118] The embodiment intelligently adjusts the running mode of the air conditioner by combining dimensional data such as the indoor environment temperature and humidity, and proposes a comfortable dehumidification mode, thereby avoiding too large temperature changes during the dehumidification process, reducing the supply air speed during the dehumidification process, and improving the user experience.

[0119] In addition, the embodiment of the present application also proposes a storage medium, and the storage medium stores an air conditioner control program. When the air conditioner control program is executed by a processor, the steps of the air conditioner control method described above are implemented.

[0120] Since the storage medium adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0121] Reference Figure 7 , Figure 7 is a structural block diagram of the first embodiment of the control device of the air conditioner of the present application.

[0122] As Figure 7 shown, the control device of the air conditioner proposed by the embodiment of the present application comprises:

[0123] The acquisition module 10 is configured to acquire the current running mode of the air conditioner, the target setting parameter, the current outdoor air parameter of the environment where the air conditioner outdoor unit is located, and the current indoor air parameter of the environment where the air conditioner indoor unit is located.
