[0003] Currently, comfort control is usually designed by setting a single temperature index, or by using a specified single temperature index and a specified single humidity index. This is usually done to meet the comfort needs of most groups.

[0004] However, due to differences in individual comfort needs, a single temperature and humidity index adjustment can no longer effectively meet people's comfort requirements, and cannot meet the differentiated and personalized thermal comfort control requirements of different users.

[0005] The present disclosure aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present disclosure is to provide an air conditioner that can meet the differentiated and personalized thermal comfort needs of different users.

[0006] Another object of the present disclosure is to provide a control method for an air conditioner.

[0026] In order to be able to understand the characteristics and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, in order to simplify the drawings, well-known structures and devices can be simplified for display. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0027] The air conditioner in the present disclosure performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged. Figure 1 , which is a schematic diagram of a refrigeration cycle system of an air conditioner according to an embodiment of the present disclosure.

[0028] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0029] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0030] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0031] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0032] In order to improve the comfort of individual users, the embodiments of the present disclosure improve the performance of the air conditioner and propose an air conditioner and a control method thereof, which can meet the comfort requirements of different individual users.

[0033] Reference below Figure 2-Figure 14 An air conditioner according to an embodiment of the present disclosure is described.

[0034] like Figure 2 FIG. 1 is a block diagram of an air conditioner according to an embodiment of the present disclosure. The air conditioner 1 of the present disclosure embodiment includes a human body temperature detection device 10, an indoor temperature detection device 20 and a controller 30. Of course, it also includes other air conditioner system components such as Figure 1 The refrigerant cycle system shown.

[0035] The human body temperature detection device 10 is used to detect the facial temperature of the target user. In an embodiment, the human body temperature detection device 10 may use an infrared detection device such as an infrared camera to collect the temperature of the exposed part of the target user, such as the facial temperature.

[0036] The indoor temperature detection device 20 is used to detect the indoor ambient temperature. Specifically, a temperature sensor can be set on the indoor unit housing to collect the indoor air temperature, that is, the indoor ambient temperature, or a temperature sensor can be set at other locations indoors, or the indoor ambient temperature can be detected by auxiliary equipment such as an intelligent robot, and the collected indoor ambient temperature data can be sent to the controller 30 of the air conditioner.

[0037] The controller 30 is connected to the human body temperature detection device 10 and the indoor temperature detection device 20. The controller 30 can pre-store a user's individual temperature and coldness perception decision tree model. The model is pre-trained, generated, detected and stored in the controller 30. The controller 30 can call up the model at any time when executing relevant decisions.

[0038] In a specific embodiment, the facial temperature includes forehead temperature, eye temperature, nose temperature and cheek temperature; the controller is configured to record the forehead temperature, eye temperature, nose temperature and cheek temperature of the target user within a preset time period, calculate the average forehead temperature, eye temperature, nose temperature and cheek temperature within the preset time period, and weightedly calculate the average forehead temperature, eye temperature, nose temperature and cheek temperature to obtain the average facial temperature, wherein the weight of the average forehead temperature > the weight of the average eye temperature > the weight of the average nose temperature > the weight of the average cheek temperature.

[0039] The user's individual temperature and coldness perception decision tree model is described below.

[0040] In the disclosed embodiment, the user's individual temperature and coldness decision tree model is a temperature and coldness prediction and recognition model for the user's individual temperature and coldness decision tree established based on human physiological parameters and environmental parameters through big data artificial intelligence technology in response to the different thermal comfort needs of individual users. It can self-learn the changing rules of the user's individual temperature and coldness sensation, accurately identify the user's individual thermal comfort needs, and perform personalized thermal comfort control to meet the differentiated and personalized thermal comfort control requirements of different individual users.

[0041] like Figure 3 As shown, it is a modeling process of establishing a user's individual temperature and coldness perception decision tree model based on big data artificial intelligence technology according to an embodiment of the present disclosure.

[0042] Specifically, first, data collection is carried out. Training data and tests can be collected in the laboratory through infrared equipment. For example, the skin temperature, such as facial temperature, of different groups of people, including the elderly, children, men, women, etc., in different seasons can be collected. It can be understood that different groups of people can reflect different human thermal sensations, metabolic rates, clothing thermal resistance, and environmental conditions in different seasons.

[0043] Secondly, the model is trained and the training data model is used for model screening and debugging and optimization. Specifically, the training data is input into the initial model, and then the initial model is debugged and optimized according to the model output results, so that the model output data can be closer to the actual situation.

[0044] Next, generate the model. Specifically, select the optimal model output from the training.

[0045] Finally, the model is predicted, and the model predicts the test data to obtain the model accuracy. For example, in the embodiment of the present disclosure, the accuracy of the user individual temperature and coldness perception decision tree model adopted can reach more than 80%.

[0046] In an embodiment, the user's individual temperature and coldness decision tree model that achieves the expected feeling can be pre-stored in the storage unit of the controller 30 of the air conditioner 1. The user's individual temperature and coldness decision tree model of the disclosed embodiment is configured with at least six layers of temperature decision condition sets, and at least six layers of temperature decision condition sets constitute multiple temperature determination branches, wherein the first layer of temperature decision condition set includes: decision conditions based on the indoor ambient temperature, the second layer of temperature decision condition set includes: decision conditions based on one facial temperature and one indoor ambient temperature, the third layer of temperature decision condition set includes: decision conditions based on two facial temperatures and two indoor ambient temperatures, the fourth layer of temperature decision condition set includes: decision conditions based on four facial temperatures and four indoor ambient temperatures, the fifth layer of temperature decision condition set includes: decision conditions based on seven facial temperatures and six indoor ambient temperatures, and the sixth layer of temperature decision condition set includes: decision conditions based on ten facial temperatures and eleven indoor ambient temperatures. For example, Figure 4-7 They are schematic diagrams of parts of a user's individual temperature and coldness decision tree model according to an embodiment of the present disclosure. The model is similar to a tree, with a left fork representing a true judgment and a right fork representing a false judgment. A series of judgments are performed each time until there is no more bifurcation, and the final result is output. In some embodiments, the user's individual temperature and coldness decision tree model may include at least six layers of temperature decision condition sets and fifty temperature determination branches consisting of at least six layers of temperature decision condition sets, and each temperature determination branch may have the same or different temperature decision conditions. Among them, each fork of the model performs an independent temperature and coldness judgment, and each temperature determination branch can output a corresponding temperature and coldness prediction result. The final value of the temperature and coldness judgment, that is, the output value of the user's individual temperature and coldness decision tree model, can be -1 (cold), 0 (neutral), 1 (hot). Therefore, the user's current temperature and coldness state can be judged according to the output value of the user's individual temperature and coldness decision tree model.

[0047] Understandably, Figure 4-7 The user individual temperature and coldness perception decision tree model shown is only an example of a model in an embodiment of the present disclosure. Other expected and applicable decision tree models may also be adopted based on the results of model training optimization and testing.

[0048] Furthermore, in the embodiments of the present disclosure, not only is it considered that the facial temperature of an individual user can reflect the user's current temperature sensation, but it is also considered that the indoor ambient temperature will also affect the user's temperature experience. Therefore, the facial temperature and the indoor ambient temperature are comprehensively considered, and the air conditioner 1 inputs the facial temperature and the indoor ambient temperature into the user's individual temperature sensation decision tree model, determines the temperature sensation state of the target user according to the output value of the user's individual temperature sensation decision tree model, adjusts the currently set target temperature according to the temperature sensation state, and controls the operation of the air conditioner according to the adjusted target temperature, thereby satisfying the temperature sensation comfort of the target user, improving the personalized and differentiated needs of the user, and improving the comfort of the air conditioner.

[0049] Among them, the currently set target temperature can be the temperature set by the user through the air conditioner control terminal such as a remote control, a wired controller or an air conditioner APP loaded on a mobile smart device when starting, or it can be the current temperature of the air conditioner when the user starts the user's individual comfort mode, which is not specifically limited here.

[0050] The air conditioner 1 of the disclosed embodiment adjusts the target temperature by adopting a user individual temperature and coldness perception decision tree model established based on big data and artificial intelligence technology, which can make up for the deficiency of the PMV prediction comfort model based on the general population that weakens individual differences, so that the air conditioner 1 not only meets the comfort needs of the general population, but also can realize the personalized comfort needs of individual household users.

[0051] Specifically, when the air conditioner 1 runs the user individual comfort mode, for example, when there is only one person in the room, the human body temperature detection device 10 collects the facial temperature of the target user in real time, the indoor temperature detection device 20 collects the indoor environment temperature in real time, the controller 30 receives the temperature data, and calls the user individual temperature and coldness decision tree model, compares the facial temperature and the indoor environment temperature with each layer of temperature decision conditions in multiple temperature judgment branches of the user individual temperature and coldness decision tree model, so as to determine the target temperature judgment branch, wherein each temperature judgment branch in the model is executed independently, and the output value of the user individual temperature and coldness decision tree model corresponding to the target temperature judgment branch is obtained, and the temperature and coldness state corresponding to the output value is used as the temperature and coldness state of the target user, for example, the output value is -1, which means that the user is cold; the output value is 0, which means that the user is neither cold nor hot, that is, a neutral state; the output value is 1, which means that the user is hot. Then, the target temperature is adjusted according to the user's current temperature and coldness state, and the compressor frequency, fan speed, air guide strip direction, etc. of the air conditioner are adjusted according to the adjusted target temperature, so as to improve the user's comfort and meet the user's personalized comfort needs.

[0052] Refer to the following Figure 4-7 The user's individual temperature and cold sensation decision tree model shown is used to illustrate the process of the controller 30 identifying the user's temperature and cold sensation state.

[0053] After the user activates the user's individual comfort model, the controller 30 obtains the facial temperature T 面部 Indicates the indoor ambient temperature with T 室内 Indicates that T 面部 and T 室内 Input user's individual temperature and coldness decision tree model, for example Figure 4-7 The tree model compares the temperature value with the temperature decision condition in the model. Each temperature decision branch is executed independently until the output value of the model is obtained, and the user's current temperature sensation state is determined based on the output value.

[0054] like Figure 4-7 As shown, each temperature determination branch is described, wherein the user individual temperature and coldness decision tree model of the disclosed embodiment uses the indoor ambient temperature as the first layer of temperature decision conditions, the facial temperature and the indoor ambient temperature as the second layer of temperature decision conditions, and continues to identify different branches with different temperature determination conditions. In the embodiment, in the user individual temperature and coldness decision tree model, the facial temperature and the indoor ambient temperature have different temperatures under different decision conditions. For example, the threshold value of each decision condition of the facial temperature is a value between 31.73°C and 37.33°C, and the threshold value of each decision condition of the indoor ambient temperature is a value between 15.95°C and 30.35°C.

[0055] In some embodiments, Figure 4 As shown, the controller 30 is configured to: determine whether the indoor ambient temperature satisfies T 室内 ≤T 室内设定1 ; If T is not satisfied 室内 ≤T 室内设定1 , then enter the ① process, refer to Figure 6 As shown.

For example, if the output is -1, the temperature and coldness state of the target user is relatively cold. That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0056] If T is not satisfied 面部 ≤T 面部设定1 , then further determine whether the indoor environment temperature T 室内 ≤T 室内设定5 , where T 室内设定5 <T 室内设定4 ; If T is satisfied 室内 ≤T 室内设定5 , the target temperature determination branch is determined to be the second temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the second temperature determination branch is obtained as a relatively cold output value.

That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0057] If T is not satisfied 室内 ≤T 室内设定5 , the target temperature determination branch is determined to be the third temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the third temperature determination branch is obtained as a relatively cold output value. For example, if the output is -1, the temperature and coldness state of the target user is relatively cold.

For example, if the output is -1, the temperature and coldness state of the target user is relatively cold. That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0059] If T is not satisfied 室内 ≤T 室内设定7 , the target temperature determination branch is determined to be the fifth temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the fifth temperature determination branch is obtained as a relatively cold output value. For example, if the output is -1, the temperature and coldness state of the target user is relatively cold. That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0060] If T is not satisfied 室内 ≤T 室内设定6 , then further determine whether the indoor environment temperature T 室内 ≤T 室内设定8 , where T 室内设定6 <T 室内设定8 ; If T is satisfied 室内 ≤T 室内设定8 , determine the target temperature determination branch as the sixth temperature determination branch, obtain the output value of the user's individual temperature and coldness decision tree model corresponding to the sixth temperature determination branch as a relatively cold output value, for example, the output is -1, then the temperature and coldness state of the target user is relatively cold. That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0061] If T is not satisfied 室内 ≤T 室内设定8 , determine the target temperature determination branch as the seventh temperature determination branch, obtain the output value of the user's individual temperature and coldness decision tree model corresponding to the seventh temperature determination branch as a relatively cold output value, such as -1, then the temperature and coldness state of the target user is relatively cold. That is, the user currently feels the temperature is low, so the current set target temperature is increased to increase the user's body temperature and improve comfort.

[0062] In some embodiments, Figure 4 As shown, the controller 30 is also configured to: if T 室内 ≤T 室内设定3 , then further determine whether the indoor environment temperature T 室内 ≤T 室内设定9 , where T 室内设定3 <T 室内设定9 ; If T is satisfied 室内 ≤T 室内设定9 , then further determine whether the indoor environment temperature T 室内≤T 室内设定10 , where T 室内设定10 <T 室内设定9 ; If T is satisfied 室内 ≤T 室内设定10 , then further determine whether the facial temperature T 面部 ≤T 面部设定2 , where T 面部设定1 <T 面部设定2 ; If the facial temperature T 面部 ≤T 面部设定2 , the target temperature determination branch is determined to be the eighth temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the eighth temperature determination branch is obtained as a relatively cold output value. For example, if the output is -1, the temperature and coldness state of the target user is relatively cold. That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0063] If T is not satisfied 面部 ≤T 面部设定2 , the target temperature determination branch is determined to be the ninth temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the ninth temperature determination branch is obtained as a relatively cold output value. For example, if the output is -1, the temperature and coldness state of the target user is relatively cold. That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0064] In some embodiments, Figure 4 As shown, the controller 30 is also configured to: if T 室内 ≤T 室内设定10 , then further determine whether the facial temperature T 面部 ≤T 面部设定3 , where T 面部设定2 <T 面部设定3 ; If T is satisfied 面部 ≤T 面部设定3 , the target temperature determination branch is determined to be the tenth temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the tenth temperature determination branch is obtained as a neutral output value, such as 0, and the temperature and coldness state of the target user is neutral. That is, the user currently feels neither cold nor hot. At this time, the currently set target temperature can be maintained, that is, the air conditioner can currently meet the user's individual comfort needs.

For example, if the output is -1, the temperature and coldness state of the target user is relatively cold. That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0066] In some embodiments, Figure 4 As shown, the controller 30 is configured as follows: if T 室内 ≤T 室内设定9 , then further determine whether the indoor environment temperature T 室内 ≤T 室内设定11 , where T 室内设定9 <T 室内设定11 ; If T is satisfied 室内 ≤T 室内设定11 , then further determine whether the indoor environment temperature T 室内 ≤T 室内设定12 , where T 室内设定12 <T 室内设定11 ; If T is satisfied 室内 ≤T 室内设定12 , the target temperature determination branch is determined to be the twelfth temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the twelfth temperature determination branch is obtained as a relatively cold output value. For example, if the output is -1, the temperature and coldness state of the target user is relatively cold.

That is, the user currently feels that the temperature is too high, so the current set target temperature is lowered to reduce the user's body temperature and improve comfort.

[0068] If T is not satisfied 室内 ≤T 室内设定11 , then further determine whether the facial temperature T 面部 ≤T 面部设定4 , where T 面部设定2 <T 面部设定4 ; If T is satisfied 面部 ≤T 面部设定4, then the target temperature determination branch is determined to be the fourteenth temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the fourteenth temperature determination branch is obtained as a relatively cold output value. For example, if the output is -1, the temperature and coldness state of the target user is relatively cold. That is, the user currently feels that the temperature is relatively low, so the current set target temperature is increased to increase the user's perceived temperature and improve comfort.

[0069] If T is not satisfied 面部 ≤T 面部设定4 , then the target temperature determination branch is determined to be the fifteenth temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the fifteenth temperature determination branch is obtained as a relatively cold output value. For example, if the output is -1, the temperature and coldness state of the target user is relatively cold.

[0103] In some embodiments, Figure 7 As shown, the controller 30 is configured as follows: if T 面部 ≤T 面部设定18 , then further determine whether the facial temperature T 面部 ≤T 面部设定24 , where T 面部设定18 <T 面部设定24 ; If T is satisfied 面部 ≤T 面部设定24 , the target temperature determination branch is determined to be the 49th temperature determination branch, and the output value of the user's individual temperature and coldness decision tree model corresponding to the 49th temperature determination branch is obtained as a neutral output value, for example, the output is 0, and the temperature and coldness state of the target user is neutral.

That is, the user currently feels neither cold nor hot. At this time, the currently set target temperature can be maintained, that is, the air conditioner can currently meet the user's individual comfort needs.

[0105] The above is adopted as Figure 4-7 The process of the user's individual temperature and coldness decision tree model judging the user's temperature and coldness state is shown. It can be understood that the user's individual temperature and coldness recognition process of other models is similar to the above process, but the model's hierarchy, temperature determination branches, and temperature decision conditions of each node of each branch are different from the model disclosed in the present invention.

[0106] Furthermore, in some embodiments, in order to improve the accuracy of identifying the user's current temperature and coldness based on the above-mentioned user individual temperature and coldness decision tree model, the controller 30 is also configured to periodically input the facial temperature and indoor environment temperature into the user individual temperature and coldness decision tree model to obtain a preset number of output values ​​output by the user individual temperature and coldness decision tree model, count and classify the preset number of output values, and use the temperature and coldness state corresponding to the output value in the classification containing the most output values ​​as the temperature and coldness state of the target user. In this way, the accuracy of identifying the user's individual temperature and coldness can be improved, and then the model can also be further optimized by self-machine learning, further improving the accuracy of the recognition result, forming a virtuous circle.

[0107] In some embodiments, the controller 30 is further configured as follows: when the air conditioner 1 is in the heating mode, if the target user's temperature and coldness state is determined to be cold for a preset number of consecutive times, the indoor fan speed of the air conditioner 1 is increased; when the air conditioner 1 is in the heating mode, if the target user's temperature and coldness state is determined to be hot for a preset number of consecutive times, the indoor fan speed of the air conditioner 1 is reduced; when the air conditioner 1 is in the cooling mode, if the target user's temperature and coldness state is determined to be cold for a preset number of consecutive times, the indoor fan speed of the air conditioner 1 is reduced; when the air conditioner 1 is in the cooling mode, if the target user's temperature and coldness state is determined to be hot for a preset number of consecutive times, the indoor fan speed of the air conditioner 1 is increased. For example, the controller 30 uses the user's individual temperature and coldness decision tree model to perform three judgments to obtain independent temperature and coldness judgment values ​​(-1, 0, 1), and then performs statistics, and the temperature and coldness corresponding to the most statistics is the output value of the final temperature and coldness judgment.

[0108] For example, Figure 8As shown, it is a flow chart of the overall operation logic of the air conditioner comfort control according to an embodiment of the present disclosure. Among them, if the controller 30 outputs a biased heat (1) through the user's individual temperature and cold sense decision tree model, the controller 30 sends a cooling signal to reduce 1°C based on the existing set temperature. If the controller 30 outputs a biased cool (-1) through the user's individual temperature and cold sense decision tree model, the controller 30 sends a heating signal to increase 1°C based on the existing set temperature. If the controller 30 outputs a neutral (0) through the user's individual temperature and cold sense decision tree model, the controller 30 keeps the existing setting unchanged, and each judgment cycle is based on the air conditioning feedback time. If the temperature and cold sense predictions for three consecutive cycles are all biased cool (or hot), it is considered that the user's individual cold and hot sense is strong, and the wind speed needs to be increased by one level, otherwise the air conditioning wind speed remains unchanged according to the original setting.

[0109] In some embodiments, the second aspect of the present disclosure further provides a control method for an air conditioner, which can be executed by a controller of the air conditioner, and the control method includes: receiving the facial temperature of a target user and the indoor ambient temperature; inputting the facial temperature and the indoor ambient temperature into a user's individual temperature and coldness decision tree model, determining the temperature and coldness state of the target user according to the output value of the user's individual temperature and coldness decision tree model, adjusting the currently set target temperature according to the temperature and coldness state, and controlling the operation of the air conditioner according to the adjusted target temperature, wherein at least six layers of temperature decision condition sets are configured in the user's individual temperature and coldness decision tree model, and the at least six layers of temperature decision condition sets constitute multiple temperature determination branches, wherein the first layer of temperature decision condition sets includes: decision conditions based on the indoor ambient temperature, The second layer of temperature decision condition set includes: decision conditions based on one facial temperature and one indoor ambient temperature, the third layer of temperature decision condition set includes: decision conditions based on two facial temperatures and two indoor ambient temperatures, the fourth layer of temperature decision condition set includes: decision conditions based on four facial temperatures and four indoor ambient temperatures, the fifth layer of temperature decision condition set includes: decision conditions based on seven facial temperatures and six indoor ambient temperatures, and the sixth layer of temperature decision condition set includes: decision conditions based on ten facial temperatures and eleven indoor ambient temperatures; the temperature and coldness state of the target user is determined according to the output value of the user's individual temperature and coldness sense decision tree model; the currently set target temperature is adjusted according to the temperature and coldness state, and the operation of the air conditioner is controlled according to the adjusted target temperature.

[0110] Of course, in an embodiment, the control method of the air conditioner of the embodiment of the present disclosure may also include other contents executed by the controller of the above air conditioner, such as how to obtain the facial temperature, and how to identify the user's current temperature and coldness state based on the user's individual temperature and coldness decision tree model. Please refer to the above description and will not repeat it here.

[0111] As described above, the present invention aims at the different thermal comfort needs of individual users, uses artificial intelligence technology based on big data to establish a user's individual temperature and coldness decision tree model, self-learns the changing rules of user temperature and coldness, accurately identifies the user's individual thermal comfort needs, and performs personalized thermal comfort control to meet the differentiated and personalized comfort control requirements of different users. At the same time, it makes up for the deficiency that the PMV prediction comfort model based on the general population weakens individual differences, so that the air conditioner 1 not only meets the comfort needs of the general population, but also can realize the personalized comfort needs of individual family users.

[0112] In the embodiment, for individual users, for example, there is only one user in the room, the user selects the user individual comfort mode, or the air conditioner 1 detects that there is only one user in the room and automatically starts the user individual comfort mode, then the air conditioner 1 can execute the user individual comfort mode according to the above embodiment to improve the user individual comfort. However, when there are multiple people in the room, the air conditioner 1 will run the TMS (Thermal and humidity Management System) comfort mode based on the PMV predictive comfort model that is suitable for the general population.

[0113] In some embodiments, when the air conditioner 1 is automatically running, the indoor user detection function can be started to detect how many people are in the room. If there is only one person, the user individual comfort mode can be automatically started, and if there are multiple people, the TMS comfort mode can be run.

[0114] For user individual comfort mode, such as Fig. 9 As shown, when the air conditioner 1 is running, the user's individual comfort mode is activated, and the indoor temperature and humidity are collected, and then the controller 30 calculates the target temperature or receives the target temperature set by the user. The controller 30 receives the target user's facial temperature and the indoor environment temperature and calls the user's individual temperature and coldness decision tree model, and then adjusts the target temperature according to the model output value, and then controls the air conditioner to operate automatically based on the adjusted target temperature, so as to meet the personalized comfort needs of individual users and improve user comfort.

[0115] The TMS comfort mode based on the PMV predictive comfort model is explained below.

[0116] In some embodiments, the TMS comfort mode can effectively adjust the air conditioner cooling / heating comfort control method of the air conditioner comfort, effectively solves the technical problem of how the air conditioner is controlled through temperature indicators and humidity indicators, and divides the entire comfortable cooling / heating stage into three stages: initial comfort stage + stable comfort stage + healthy comfort stage. It not only effectively meets people's perfect experience of cooling comfort requirements, but also realizes the perfect combination of comfort and energy saving: in the healthy comfort stage, according to the thermal adaptability characteristics of the human body, the target setting temperature is further increased by 1°C, that is, Ts_chieh = Ts_comfort + 1°C, achieving the purpose of both comfort and energy saving.

[0117] In the embodiment, the TMS comfort mode must first be addressed by the target value of temperature and humidity. The temperature and humidity addressing rule is based on the calculation of the estimated average thermal sensation index value of the human thermal sensation index PMV. The "comfort temperature and humidity reference table (PMV value is ± 0.5)" is generated by calculation as the reference table for comfort control of the air conditioner. The air conditioner detects the outdoor ambient temperature Tout, the indoor ambient temperature Tin, and the indoor relative humidity Rh through sensors. According to the obtained outer ring Tout, enter the corresponding temperature zone, combine the thermal resistance clo of the human clothing, and the human activity metabolic rate M to obtain different temperature compensation values ​​T compensation, and judge the specific operation mode of the air conditioner (cooling / heating / air supply). According to the comfort temperature and humidity reference table, the obtained indoor relative humidity Rh is used as a pointer to address in the reference table, determine the target setting temperature Ts_comfort in the stable comfort stage, and the air conditioner runs with Ts_comfort as the target setting value.

[0118] In some embodiments, for the TMS comfort mode, the temperature and humidity addressing from the beginning always revolves around the PMV value of six factors affecting human thermal sensation: environmental parameters (air temperature, relative humidity of air, wind speed, average radiant temperature) and human parameters (human activity intensity, clothing thermal resistance), with human comfort control as the core. Compared with the current industry practice of mainly designing and controlling comfort air conditioners through a single temperature indicator, or using a specified single temperature indicator + a specified single humidity indicator to design and control comfort air conditioners, the advantages are very obvious.

[0119] Table 1 below shows the names and meanings of various symbols in the TMS comfort mode description.

[0120] Table 1

[0121]

[0122]

[0123] In some embodiments, when the TMS comfort mode is running, the air conditioner detects the outer loop Tout, inner loop Tin, and indoor relative humidity Rh through the sensors configured by itself. According to the obtained Tout, the corresponding divided temperature zone is entered to determine the next specific operation mode (cooling / heating / air supply). Every 2 hours, a new operating temperature zone is determined based on the outer loop temperature Tout. If it is still in the original operating temperature zone, continue to maintain the original mode and stage operation; if it is in a new temperature zone, the original operating mode is interrupted and a new specific sub-mode is entered in combination with the inner loop temperature Tin and indoor relative humidity Rh of the new temperature zone. If the indoor sensor fails or overflows, and there is no humidity sensor, Rh defaults to 65%.

[0124] In some embodiments, addressing is performed according to the comfort temperature and humidity reference table, and the corresponding temperature zone is entered according to the obtained Tout. The mode to be entered is determined, including cooling, heating, air supply, etc., and then addressing is performed according to the rules under different modes, as follows.

[0128]

[0129]

[0130] In some embodiments, when the air conditioner operates in cooling mode, Fig.10 As shown, the addressing process is as follows:

[0131] According to Table 3, the standard comfort table. If Rh < 30% (the lower limit of the comfort table), the minimum temperature corresponding to Rh30% in the comfort table is Ts_ 初 (Ts_ 初 =24.5℃); if Rh>65% (the upper limit of the comfort table), the lowest temperature corresponding to Rh65% in the comfort table is Ts_ 初 (Ts_ 初 =23.5℃); if 65% ≥ Rh ≥ 30% (the upper and lower limits of the comfort table), the lowest temperature corresponding to the closest humidity in the comfort table is Ts_ 初 (For example, Rh = 43%, the closest humidity in the comfort table is Rh = 45%, then the lowest temperature corresponding to Rh = 45% is Ts_ 初 =24℃). The average value (25.25℃) of the sum of the upper limit value of comfortable humidity (26.5℃) and the lower limit value of comfortable humidity (24℃) corresponding to Rh = 50% in the comfort table is taken as Ts_ 舒 , the default is 25.5℃.

[0132] In some embodiments, when the air conditioner operates in heating mode, Fig.11 As shown, the addressing process is as follows:

[0133] According to Table 3, the benchmark comfort table. If Rh < 30% (the lower limit of the comfort table), the maximum temperature corresponding to Rh30% in the comfort table is Ts_ 初 (Ts_ 初 =27℃); if Rh>65% (the upper limit of the comfort table), the highest temperature corresponding to Rh65% in the comfort table is Ts_ 初 (Ts_ 初 =26℃); if 65% ≥ Rh ≥ 30% (the upper and lower limits of the comfort table), the lowest temperature corresponding to the closest humidity in the comfort table is Ts_ 初 (For example, Rh = 43%, the closest humidity in the comfort table is Rh = 45%, then the highest temperature corresponding to Rh = 45% is Ts_ 初 =26.5°C). In the comfort table, the average value (25.25°C) of the sum of the upper limit value of the comfortable humidity (26.5°C) and the lower limit value of the comfortable humidity (24°C) corresponding to Rh=50% is taken as Ts_Comfortable, and the default value is 25.5°C.

[0150] In some embodiments, according to the humidity control and moisture retention theory (such as Table 5, Table 5), "with the increase of indoor environmental humidity, the peak of air conditioning dehumidification has a tendency to gradually move to the high wind speed side of the indoor unit. At different wind speeds, the critical points of dry and wet conditions are different. The higher the wind speed, the higher the inlet relative humidity can enter the wet condition; the lower the wind speed, the lower the inlet relative humidity will enter the wet condition." Fig.13 ), a method for indoor fan comfort control is proposed to better control the relative humidity of the indoor environment and keep it within the range of human comfort humidity.

[0151] Table 5 Relationship between absolute dehumidification capacity in 4 hours and indoor unit wind speed

[0152] Absolute dehumidification capacity in 4 hours 700rpm 870rpm 1000rpm 1250rpm Indoor 27℃ / 15.8℃(30%RH) 3.90kg 3.24kg 3.01kg 2.94kg Indoor 27℃ / 19℃(47%RH) 3.68kg 4.51kg 4.79kg 4.11kg Indoor 27℃ / 21.2℃(60%RH) 4.21kg 5.45kg 4.66kg 4.70kg

[0153] Based on the above humidity control and moisture retention theory, a method for indoor fan comfort control is proposed to better control the relative humidity of the indoor environment and keep it within the range of human comfort humidity. Fig.14 The indoor fan comfort control method according to an embodiment of the present disclosure is described when the operation mode of the air conditioner is a cooling mode.

[0154] Step S11, the air conditioner turns on the TMS function. Step S12, the indoor environment temperature Tin, the outdoor environment temperature Tout, the indoor environment relative humidity Rh and the indoor instantaneous sampling relative humidity Rhi are obtained.

[0155] Step S13, determining whether the air conditioner enters a cooling mode or a dehumidification mode according to the indoor environment temperature Tin, the outdoor environment temperature Tout and the indoor environment relative humidity Rh.

[0156] Step S14, the air conditioner enters cooling mode. Step S15, the speed of the indoor fan is controlled.

[0157] Step S16, determining whether the set temperature difference E is greater than a first set temperature, for example, 2°C. If so, executing step S17; if not, executing step S18.

[0158] Step S17, control the indoor fan to run at the first wind speed. Step S18, control the indoor fan to run at the second wind speed. Step S19, determine whether the set temperature difference E is less than or equal to the first set temperature, such as 2°C. If so, execute step S18; if not, execute step S17.

[0159] S20, determining whether the first temperature difference is greater than or equal to -2°C and less than or equal to 2°C within a preset time, if so, executing step S21; if not, executing step S18.

[0160] Step S21, determining whether the second temperature difference is greater than or equal to -6 and less than 6, if so, executing step 20; if not, executing step S22.

[0161] Step S22, determine whether the second temperature difference is greater than 6, if so, execute step S23; if not, execute step S24.

[0162] Step S23, controlling the indoor fan to run at the third wind speed.

[0163] Step S24, determining whether the second temperature difference is less than -6, if yes, executing step S25, if not, executing step S21.

[0164] Step S25, controlling the indoor fan to run at the fourth wind speed.

[0165] Through the above steps S11-S25, the energy consumption of the air conditioner can be reduced while ensuring the user's comfort.

[0166] The TMS comfort mode based on the PMV model according to the embodiment of the present disclosure is described above.

[0167] In summary, the air conditioner of the disclosed embodiment can set the user individual comfort mode and TMS comfort mode. Among them, since the PMV model is an average thermal sensation prediction model based on the general population, it weakens the influence of individual differences of users. In order to meet the personalized and differentiated thermal comfort needs of household air conditioners, especially individual household users, a user individual temperature and coldness decision tree model is established by using artificial intelligence technology based on big data, and the user temperature and coldness change law is self-learned to accurately identify the user's individual thermal comfort needs, and personalized thermal comfort control is performed to meet the differentiated and personalized comfort control requirements of different users. It also makes up for the deficiency of the PMV prediction comfort model based on the general population that weakens individual differences, so that the air conditioner not only meets the comfort needs of the general population, but also can realize the personalized comfort needs of individual household users.

[0168] The user individual temperature and coldness decision tree model of the disclosed embodiment is based on a machine learning method, and its accuracy depends largely on the amount of data involved in the training. Therefore, in practical applications, as the amount of data continues to increase, its accuracy will also increase. Ideally, the temperature and coldness prediction model based on skin temperature can achieve fully automated control without the need for human intervention to adjust parameters.
