[0001] The present disclosure relates to the technical field of air conditioners, and in particular to an air conditioner and a control method of the air conditioner. BACKGROUND

[0002] Air conditioners are widely used in people's lives, and air conditioners play an important role in indoor temperature regulation, which can provide a healthy and comfortable indoor environment for users to meet the needs of normal work, life and study.

[0003] Currently, the comfort is usually designed by setting a single temperature index, or a single temperature index and a single humidity index are specified to design the comfort, so as to meet the comfort needs of most groups.

[0004] However, due to the difference in individual comfort needs, a single temperature and a single humidity index cannot effectively meet the requirements of people on comfort, and cannot meet the differentiated and personalized thermal comfort control requirements of different users. SUMMARY

[0005] The present disclosure aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present disclosure is to provide an air conditioner which 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 of the air conditioner.

[0008] The control method of the air conditioner of the second aspect embodiment of the present disclosure comprises: receiving the face temperature of a target user and the indoor environment temperature; inputting the face temperature and the indoor environment temperature into a user individual temperature and cold sensation decision tree model, determining the temperature and cold sensation state of the target user according to the output value of the user individual temperature and cold sensation decision tree model, adjusting the current set target temperature according to the temperature and cold sensation state, and controlling the air conditioner to operate according to the adjusted target temperature, wherein at least six layers of temperature decision condition sets are configured in the user individual temperature and cold sensation decision tree model, and the at least six layers of temperature decision condition sets constitute a plurality of temperature judgment branches, wherein the first layer of temperature decision condition set comprises a decision condition based on the face temperature, the second layer of temperature decision condition set comprises a decision condition based on the face temperature and the indoor environment temperature, the third layer of temperature decision condition set comprises a decision condition based on two face temperatures and two indoor environment temperatures, the fourth layer of temperature decision condition set comprises a decision condition based on five face temperatures and three indoor environment temperatures, the fifth layer of temperature decision condition set comprises a decision condition based on seven face temperatures and five indoor environment temperatures, and the sixth layer of temperature decision condition set comprises a decision condition based on eleven face temperatures and nine indoor environment temperatures; the temperature and cold sensation state of the target user is determined according to the output value of the user individual temperature and cold sensation decision tree model; the current set target temperature is adjusted according to the temperature and cold sensation state, and the air conditioner is controlled to operate according to the adjusted target temperature.

[0009] The air conditioner and the control method thereof of the embodiment of the present disclosure can compensate for the deficiency that the PMV (Predicted Mean Vote) predicted comfort model based on the general population weakens individual differences by adjusting the target temperature based on the user individual temperature and cold sensation decision tree model established based on big data and artificial intelligence technology, and not only considers that the face temperature of the user individual can experience the current temperature and cold sensation of the user, but also considers that the indoor environment temperature also affects the temperature and cold sensation experience of the user, so the air conditioner inputs the face temperature and the indoor environment temperature into the user individual temperature and cold sensation decision tree model, thereby meeting the temperature and cold sensation comfort of the target user individual, improving the individualization and differentiation needs of the user individual, and improving the comfort of the air conditioner.

[0026] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings, which are for reference only and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to facilitate the drawings. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall 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 adjusted and heat-exchanged. As shown in FIG. 1, a schematic diagram of a refrigeration cycle system of an air conditioner according to an embodiment of the present disclosure. Figure 1

[0028] The compressor compresses 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 heat is released to the surrounding environment through the condensation process.

[0029] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase 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 heat-exchanging with a material to be cooled using latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

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

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

[0032] In order to improve the individual comfort of 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 needs of different individual users.

[0033] Reference will now be made to the following detailed description of the embodiments of the present disclosure with reference to the accompanying drawings. Figures 2-14 ​An air conditioner according to an embodiment of the present disclosure is described.

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

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

[0036] The indoor temperature detection device 20 is used to detect the indoor ambient temperature. Specifically, a temperature sensor can be installed on the indoor unit casing to collect the indoor air temperature, i.e., the indoor ambient temperature, or a temperature sensor can be installed in other locations indoors, or an auxiliary device such as an intelligent robot can be used to detect the indoor ambient temperature and send the collected indoor ambient temperature data to the air conditioner controller 30.

[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 the user's individual temperature and coldness decision tree model. This model is pre-trained, generated, detected and stored in the controller 30. The controller 30 can retrieve the model at any time when making relevant decisions.

[0038] In a specific embodiment, 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, average eye temperature, average nose temperature, and average cheek temperature within the preset time period, and perform a weighted calculation on the average forehead temperature, average eye temperature, average nose temperature, and average cheek temperature to obtain the average facial temperature, wherein the weight of the average forehead temperature is greater than the weight of the average eye temperature, which is greater than the weight of the average nose temperature, which is greater than the weight of the average cheek temperature.

[0039] The following is an explanation of the individual user's temperature and coldness decision tree model.

[0040] In the embodiments of the present disclosure, the user individual temperature and cold sensation decision tree model is a user individual temperature and cold sensation decision tree temperature and cold sensation prediction and identification model established based on human physiological parameters and environmental parameters through big data artificial intelligence technology for different thermal comfort needs of individual users, which self-learns the user individual temperature and cold sensation change rule, accurately identifies the user individual thermal comfort needs, performs personalized thermal comfort control, and meets the differentiated and personalized thermal comfort control requirements of different user individuals.

[0041] As shown in FIG. 1, it is a modeling process of establishing a user individual temperature and cold sensation decision tree model based on big data artificial intelligence technology according to an embodiment of the present disclosure. Figure 3

[0042] Specifically, first, data collection is performed. The training data and testing can be collected in a laboratory through infrared equipment, for example, the skin temperature such as the facial temperature of different people including the elderly, children, men, women, etc. in different seasons is collected. It can be understood that different people in different seasons can reflect different human thermal sensations, metabolic rates, clothing thermal resistances, and environmental states, etc.

[0043] Secondly, model training is performed. The training data model is filtered and debugged and optimized. Specifically, the training data is input into the initial model, and then the initial model is debugged and optimized according to the model output result, so that the model output data can be closer to the real situation.

[0044] Thirdly, the model is generated. Specifically, the optimal model output of the training is selected.

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

[0046] In the embodiments, the user individual temperature and cold sensation decision tree model meeting the expectations can be stored in the storage unit of the controller 30 of the air conditioner 1 in advance. The user individual temperature and cold sensation decision tree model of the embodiments of the present disclosure is configured with at least six layers of temperature decision condition sets, and the at least six layers of temperature decision condition sets constitute a plurality of temperature determination branches. The first layer of temperature decision condition set includes a decision condition based on facial temperature, the second layer of temperature decision condition set includes a decision condition based on facial temperature and indoor environment temperature, the third layer of temperature decision condition set includes a decision condition based on two facial temperatures and two indoor environment temperatures, the fourth layer of temperature decision condition set includes a decision condition based on five facial temperatures and three indoor environment temperatures, the fifth layer of temperature decision condition set includes a decision condition based on seven facial temperatures and five indoor environment temperatures, and the sixth layer of temperature decision condition set includes a decision condition based on eleven facial temperatures and nine indoor environment temperatures. For example,​Figures 4-7 respectively are schematic diagrams of parts of a user individual thermal sensation decision tree model according to an embodiment of the present disclosure, the model morphology is similar to a tree, the left branch represents the judgment as true, the right branch represents the judgment as false, a series of judgments are performed each time until there is no longer a branch, and the final result is output. In some embodiments, the user individual thermal sensation decision tree model can include at least six layers of temperature decision condition sets and forty-eight temperature judgment branches composed of the at least six layers of temperature decision condition sets, each temperature judgment branch can have the same or different temperature decision conditions. Wherein each branch of the model performs an independent thermal sensation judgment, each temperature judgment branch can output a corresponding thermal sensation prediction result, and the final value of the thermal sensation judgment is the output value of the user individual thermal sensation decision tree model, which can be -1 (cold), 0 (neutral), and 1 (hot). Therefore, the current thermal sensation state of the user can be determined according to the output value of the user individual thermal sensation decision tree model.

[0047] It can be understood that, Figures 4-7 The user individual thermal sensation decision tree model shown is only an example of a model of an embodiment of the present disclosure, and other suitable decision tree models that meet expectations can also be used based on the results of model training optimization and testing.

[0048] Further, in an embodiment of the present disclosure, not only the facial temperature of the user individual can reflect the current thermal sensation of the user, but also the indoor environment temperature can also affect the thermal sensation experience of the user. Therefore, the facial temperature and the indoor environment temperature are input into the user individual thermal sensation decision tree model, the thermal sensation state of the target user is determined according to the output value of the user individual thermal sensation decision tree model, the current set target temperature is adjusted according to the thermal sensation state, and the air conditioner is controlled to operate according to the adjusted target temperature, so as to meet the thermal sensation comfort requirement of the target user individual, improve the individualization and differentiation requirement of the user individual, and improve the comfort of the air conditioner.

[0049] Wherein, the current set target temperature can be the temperature set by the user through the control terminal of the air conditioner, such as a remote controller, a wire controller, or an air conditioner APP loaded on a mobile intelligent device when the user starts the user individual comfort mode, which is not specifically limited here.

[0050] The air conditioner 1 of an embodiment of the present disclosure adjusts the target temperature by using the user individual thermal sensation 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 the individual difference, so that the air conditioner 1 not only meets the comfort requirement of the general population, but also can realize the individual comfort requirement of a single family user.

[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 face 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 cold and hot feeling decision tree model, compares the face temperature and the indoor environment temperature with each layer of temperature decision condition in the multiple temperature decision branches of the user individual temperature cold and hot feeling decision tree model to determine the target temperature decision branch, wherein each temperature decision branch in the model is independently executed, obtains the output value of the target temperature decision branch of the user individual temperature cold and hot feeling decision tree model, and takes the temperature cold and hot feeling state corresponding to the output value as the temperature cold and hot feeling state of the target user, for example, the output value is -1, which represents that the user is cold; the output value is 0, which represents that the user is neither cold nor hot, i.e., neutral state; and the output value is 1, which represents that the user is hot. Then, the target temperature is adjusted according to the current temperature cold and hot feeling state of the user, and the compressor frequency, fan speed, air guide bar direction, etc. of the air conditioner are adjusted according to the adjusted target temperature, so that the user comfort can be improved and the user individual comfort demand can be met.

[0052] The process of identifying the temperature cold and hot feeling state of the user by the controller 30 will be described below with reference to the user individual temperature cold and hot feeling decision tree model shown in Figures 4-7 .

[0053] After the user enables the user individual comfort model, the controller 30 obtains the face temperature represented by T 面部 and the indoor environment temperature represented by T 室内 , and inputs T 面部 and T 室内 into the tree model of the user individual temperature cold and hot feeling decision tree model, for example, Figures 4-7 , compares the temperature values with the temperature decision conditions in the model, each temperature decision branch is independently executed until the output value of the model is obtained, and the current temperature cold and hot feeling state of the user is determined based on the output value.

[0054] As shown in Figures 4-7 , each temperature decision branch is described, wherein the user individual temperature cold and hot feeling decision tree model of the embodiment of the present disclosure identifies the face temperature as the first layer of temperature decision condition, the face temperature and the indoor environment temperature as the second layer of temperature decision condition, and continues to different branches with different temperature decision conditions. In the embodiment, in the user individual temperature cold and hot feeling decision tree model, the face temperature and the indoor environment temperature have different temperatures in different decision conditions, for example, the threshold value of each decision condition of the face temperature is a value between 31.42°C and 37.33°C, and the threshold value of each decision condition of the indoor environment temperature is a value between 16.35°C and 30.95°C.

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

[0101] In some embodiments, such as Figure 7 As shown, controller 30 is configured to: if T is not satisfied 室内 ≤T 室内设定20 Then, further determine whether the facial temperature T is met. 面部 ≤T 面部设定27 , among which, T 面部设定27 <T 面部设定26 If T is satisfied 面部 ≤T 面部设定27 If the target temperature decision branch is determined to be the forty-seventh temperature decision branch, and the output value of the forty-seventh temperature decision branch corresponding to the user's individual temperature and coldness decision tree model is obtained as a neutral output value (e.g., an output of 0), then the target user's temperature and coldness state is neutral. That is, the user currently feels neither cold nor hot, and at this time, the current set target temperature can be maintained, meaning the air conditioner can currently meet the user's individual comfort needs.

[0102] If T is not satisfied 面部 ≤T面部设定27 If yes, the target temperature determination branch is determined as the forty-eighth temperature determination branch, and the output value of the user individual temperature and thermal sensation decision tree model corresponding to the forty-eighth temperature determination branch is obtained as a neutral output value, for example, the output is 0, and the thermal sensation state of the target user is neutral. That is, the user currently feels neither cold nor hot, and at this time, the current set target temperature can be maintained, that is, the air conditioner can currently meet the individual comfort needs of the user.

[0103] The above is the process of determining the thermal sensation state of the user by using the user individual temperature and thermal sensation decision tree model as shown in Figures 4-7 It can be understood that the user individual temperature and thermal sensation recognition process of other models is similar to the above process, but the levels of the model, the temperature determination branches, and the temperature decision conditions of each node of each branch are different from those of the model of the present disclosure.

[0104] Further, in some embodiments, in order to improve the accuracy of recognizing the current thermal sensation of the user based on the above user individual temperature and thermal sensation decision tree model, the controller 30 is further configured to periodically input the facial temperature and the indoor environment temperature into the user individual temperature and thermal sensation decision tree model to obtain a preset number of output values output by the user individual temperature and thermal sensation decision tree model, to statistically and classify the preset number of output values, and to take the thermal sensation state corresponding to the output value in the classification containing the most output values as the thermal sensation state of the target user. Thus, the accuracy of the user individual temperature and thermal sensation recognition can be improved, and the model can also perform machine learning to further optimize and further improve the accuracy of the recognition result, forming a virtuous cycle.

[0105] In some embodiments, the controller 30 is further configured to: when the air conditioner 1 is in the heating mode, the thermal sensation state of the target user is determined to be cold for a continuous preset number of times, the indoor fan speed of the air conditioner 1 is increased; when the air conditioner 1 is in the heating mode, the thermal sensation state of the target user is determined to be hot for a continuous preset number of times, the indoor fan speed of the air conditioner 1 is reduced; when the air conditioner 1 is in the cooling mode, the thermal sensation state of the target user is determined to be cold for a continuous preset number of times, the indoor fan speed of the air conditioner 1 is reduced; and when the air conditioner 1 is in the cooling mode, the thermal sensation state of the target user is determined to be hot for a continuous preset number of times, the indoor fan speed of the air conditioner 1 is increased. For example, the controller 30 performs three independent thermal sensation judgments by using the user individual temperature and thermal sensation decision tree model to obtain independent thermal sensation judgment values (-1, 0, 1), and then performs statistics to obtain the most corresponding thermal sensation as the output value of the final thermal sensation determination.

[0106] For example, as shown in Figure 8Fig. 6 shows a flow chart of the overall operation logic of the air conditioner comfort control according to an embodiment of the present disclosure. If the controller 30 outputs that the user is slightly hot (1) through the user individual thermal sensation decision tree model, the controller 30 sends a cooling signal to reduce the set temperature by 1°C. If the controller 30 outputs that the user is slightly cold (-1) through the user individual thermal sensation decision tree model, the controller 30 sends a heating signal to increase the set temperature by 1°C. If the controller 30 outputs that the user is neutral (0) through the user individual thermal sensation decision tree model, the controller 30 keeps the set temperature unchanged. The air conditioner feedback time is used as the judgment period. If the thermal sensation prediction is cold (or hot) for three consecutive periods, it is considered that the user has a strong thermal sensation, and the air conditioner speed needs to be increased by one level. Otherwise, the air conditioner speed remains unchanged according to the original setting.

[0107] In some embodiments, the second aspect of the present disclosure also proposes a control method of an air conditioner, which can be executed by the controller 30 of the air conditioner. The control method comprises: receiving a face temperature of a target user and an indoor environment temperature; inputting the face temperature and the indoor environment temperature into a user individual thermal sensation decision tree model, determining a thermal sensation state of the target user according to an output value of the user individual thermal sensation decision tree model, adjusting a current set target temperature according to the thermal sensation state, and controlling the air conditioner to operate according to the adjusted target temperature. In the user individual thermal sensation decision tree model, at least six layers of temperature decision condition sets are configured, which constitute a plurality of temperature judgment branches. The first layer of temperature decision condition set comprises a decision condition based on the face temperature. The second layer of temperature decision condition set comprises a decision condition based on the face temperature and the indoor environment temperature. The third layer of temperature decision condition set comprises a decision condition based on two face temperatures and two indoor environment temperatures. The fourth layer of temperature decision condition set comprises a decision condition based on five face temperatures and three indoor environment temperatures. The fifth layer of temperature decision condition set comprises a decision condition based on seven face temperatures and five indoor environment temperatures. The sixth layer of temperature decision condition set comprises a decision condition based on eleven face temperatures and nine indoor environment temperatures. The thermal sensation state of the target user is determined according to the output value of the user individual thermal sensation decision tree model. The current set target temperature is adjusted according to the thermal sensation state, and the air conditioner is controlled to operate according to the adjusted target temperature.

[0108] Of course, in embodiments, the control method of the air conditioner according to the embodiments of the present disclosure can also include other contents executed by the controller 30 of the air conditioner, such as how to obtain the face temperature and how to identify the current thermal sensation state of the user based on the user individual thermal sensation decision tree model. For details, please refer to the above description, which will not be repeated here.

[0109] The above, the present application aims at different thermal comfort needs of individual users, establishes a user individual temperature and cold feeling decision tree model based on big data artificial intelligence technology, self-learns the user temperature and cold feeling change rule, accurately identifies the individual thermal comfort needs of the user, performs personalized thermal comfort control, and meets the comfort control requirements of different individual differences and personalization of users. At the same time, the PMV prediction comfort model based on the general population weakens the individual difference, 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.

[0110] In an embodiment, the above is for an individual user, for example, there is only one user in the room, the user individual comfort mode is selected by the user, 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, and improve the individual comfort of the user. 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 prediction comfort model suitable for the general population.

[0111] 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. When there is one person, the user individual comfort mode can be automatically started, and when there are multiple people, the TMS comfort mode can be run.

[0112] For the user individual comfort mode, as shown in Figure 9 When the air conditioner 1 is running, the user individual comfort mode is activated, 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 face temperature and the indoor environment temperature and calls the user individual temperature and cold feeling decision tree model, and then adjusts the target temperature according to the model output value, and then controls the air conditioner to run based on the adjusted target temperature, meets the individual comfort needs of the individual user, and improves the user comfort.

[0113] The TMS comfort mode based on the PMV prediction comfort model is described below.

[0114] In some embodiments, the TMS comfort mode is an air conditioner cooling / heating comfort control method that effectively adjusts the comfort level of the air conditioner. It effectively solves the technical problem of how to control the air conditioner through temperature and humidity indicators. The entire comfortable cooling / heating stage is divided into three stages: initial comfort stage + stable comfort stage + healthy comfort stage. It not only effectively meets people's requirements for a perfect experience of cooling comfort, but also achieves a perfect combination of comfort and energy saving. In the healthy comfort stage, according to the thermal adaptability characteristics of the human body, the target set temperature is raised by 1℃, that is, Ts_saving = Ts_comfort + 1℃, which achieves the purpose of both comfort and energy saving.

[0115] In this embodiment, the TMS comfort mode first relies on temperature and humidity target values ​​for addressing. The temperature and humidity addressing rule is calculated based on the predicted average thermal perception index (PMV) of the human body, generating a "comfort temperature and humidity benchmark table (PMV value within ±0.5)" as the benchmark table for the air conditioner's comfort control. The air conditioner detects the outdoor ambient temperature Tout, indoor ambient temperature Tin, and indoor relative humidity Rh through sensors. It enters the corresponding temperature zone according to the acquired outer ring Tout, and combines this with the thermal resistance clo of human clothing and the metabolic rate M of human activity to obtain different temperature compensation values ​​T_compensation, and determines the specific operating mode of the air conditioner (cooling / heating / ventilation). Then, based on the comfort temperature and humidity benchmark table, and using the acquired indoor relative humidity Rh as a pointer, it addresses within the benchmark table to determine the target set temperature Ts_comfort for the stable comfort stage. The air conditioner operates with Ts_comfort as the target set value.

[0116] In some embodiments, for the TMS comfort mode, the initial temperature and humidity addressing always revolves around the six factors affecting human thermal sensation: environmental parameters (air temperature, relative humidity, wind speed, mean radiant temperature) and human parameters (human activity intensity, clothing thermal resistance). With human comfort control as the core, this approach has significant advantages over the current industry practice of designing and controlling comfort air conditioners using a single temperature index or a single humidity index.

[0117] Table 1 below shows the names and meanings of the various symbols in the TMS Comfort Mode description.

[0118] Table 1

[0119]

[0120] In some embodiments, when the TMS comfort mode is running, the air conditioner detects the outer ring Tout, the inner ring Tin, and the indoor relative humidity Rh through the sensors configured by itself. According to the obtained Tout, the corresponding division temperature zone is entered, and the next specific running mode (cooling / heating / air supply) is determined. Every 2 hours, the new running temperature zone is determined according to the outer ring temperature Tout. If it is still in the original running temperature zone, the original mode and stage running are continued to be maintained; if it is in the new temperature zone, the original running mode is interrupted, and the new specific sub-mode running is entered in combination with the inner ring temperature Tin and the indoor relative humidity Rh in the new temperature zone. The indoor sensor fails or overflows, and the humidity sensor is not available, and Rh is defaulted to 65%.

[0121] In some embodiments, according to the comfort temperature and humidity reference table, the obtained Tout is entered into the corresponding temperature zone, the mode to be entered is determined, including cooling, heating, air supply, etc., and then the rules in different modes are addressed, which are as follows.

[0126] In some embodiments, when the air conditioner runs in the cooling mode, the addressing process is as shown in the following table. Figure 10

[0127] According to the reference comfort table in Table 3. If Rh<30% (the lower limit value of the comfort humidity in the comfort table), the lowest temperature corresponding to Rh30% in the comfort table is taken as Ts_ 初 (Ts_ 初 = 24.5℃); if Rh>65% (the upper limit value of the comfort humidity in the comfort table), the lowest temperature corresponding to Rh65% in the comfort table is taken as Ts_ 初 (Ts_ 初 = 23.5℃); if 65%≥Rh≥30% (the upper and lower limit values of the comfort humidity in the comfort table), the lowest temperature corresponding to the closest humidity in the comfort table is taken as Ts_ 初 (for example, Rh=43%, the closest humidity in the comfort table is Rh=45%, and the lowest temperature corresponding to Rh=45% is Ts_ 初 = 24℃).

[0128] In some embodiments, when the air conditioner runs in the heating mode, the addressing process is as shown in the following table.​Figure 11 As shown, the addressing process is as follows:

[0129] According to Table 3, the reference comfort table. If Rh < 30% (the lower limit of the comfortable humidity in the comfort table), the highest temperature corresponding to Rh 30% in the comfort table is Ts_ 初 (Ts_ 初 = 27°C); if Rh > 65% (the upper limit of the comfortable humidity in the comfort table), the highest temperature corresponding to Rh 65% in the comfort table is Ts_ 初 (Ts_ 初 = 26°C); if 65% ≥ Rh ≥ 30% (the upper and lower limits of the comfortable humidity in the comfort table), the lowest temperature corresponding to the closest humidity in the comfort table is Ts_ 初 (For example, if 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). The average value (25.25°C) of the sum of the upper limit of the comfortable humidity (26.5°C) and the lower limit of the comfortable humidity (24°C) corresponding to Rh = 50% in the comfort table is taken as Ts_shu, and the default is 25.5°C.

[0162] In summary, the air conditioner of the embodiments of the present disclosure can set a user individual comfort mode and a TMS comfort mode. Since the PMV model is an average thermal sensation prediction model based on a general population, the influence of user individual differences is weakened.

[0163] The user individual warm and cold sensation decision tree model of the embodiments of the present disclosure is based on a machine learning method, and its accuracy depends largely on the amount of data involved in the training. Therefore, in actual application, as the amount of data continues to increase, its accuracy will also improve. The warm and cold sensation prediction model based on skin temperature can achieve full automatic control without the need for personnel to adjust parameters in ideal conditions.
