Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and in particular to an air conditioner and a method for controlling the air conditioner. Background Technology

[0002] Air conditioners are a widely used electrical appliance in people's lives. They play an important role in regulating indoor temperature, providing users with a healthy and comfortable indoor environment to meet their normal work, life and study needs.

[0003] Currently, comfort is typically designed and controlled 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 the majority of the population.

[0004] However, due to differences in individual comfort needs, adjusting a single temperature and humidity level is no longer sufficient to meet people's comfort requirements and cannot satisfy the differentiated and personalized thermal comfort control requirements of different users. Summary of the Invention

[0005] This disclosure aims to at least address one of the technical problems existing in the prior art. Therefore, one object of this disclosure is to provide an air conditioner that can meet the differentiated and personalized thermal comfort needs of different users.

[0006] Another objective of this disclosure is to propose a control method for an air conditioner.

[0007] To achieve the above objectives, an air conditioner according to a first aspect of this disclosure includes: a human body temperature detection device for detecting the hand temperature of a target user; an indoor temperature detection device for detecting the indoor ambient temperature; and a controller connected to the human body temperature detection device and the indoor temperature detection device. The controller is configured to: input the hand temperature and the indoor ambient temperature into a user-specific temperature and coldness decision tree model; determine the target user's temperature and coldness state based on the output value of the user-specific temperature and coldness decision tree model; adjust a currently set target temperature based on the temperature and coldness state; and control the air conditioner to operate based on the adjusted target temperature. The user-specific temperature and coldness decision tree model is configured with at least eight layers of temperature decision condition sets, which constitute multiple temperature determination branches. The first layer of temperature decision... The set of conditions includes: a first-level decision condition based on the hand temperature; a second-level temperature decision condition set includes: a decision condition based on the hand temperature and the indoor ambient temperature; a third-level temperature decision condition includes: a decision condition based on one hand temperature and two indoor ambient temperatures; a fourth-level temperature decision condition includes: a decision condition based on five hand temperatures and one indoor ambient temperature; a fifth-level temperature decision condition includes: a decision condition based on eight hand temperatures and four indoor ambient temperatures; a sixth-level temperature decision condition includes: a decision condition based on six hand temperatures and nine indoor ambient temperatures; a seventh-level temperature decision condition includes: a decision condition based on eleven hand temperatures and eight indoor ambient temperatures; and an eighth-level temperature decision condition includes: a decision condition based on seven hand temperatures and nine indoor ambient temperatures.

[0008] A control method for an air conditioner according to a second aspect of this disclosure includes: receiving the hand temperature of a target user and the indoor ambient temperature; inputting the hand temperature and the indoor ambient temperature into a user-specific temperature and coldness perception decision tree model, wherein the user-specific temperature and coldness perception decision tree model is configured with at least eight layers of temperature decision condition sets, the at least eight layers of temperature decision condition sets constituting multiple temperature determination branches, wherein the first layer of temperature decision condition set includes: decision conditions based on the hand temperature; the second layer of temperature decision condition set includes: decision conditions based on the hand temperature and the indoor ambient temperature; the third layer of temperature decision condition includes: decision conditions based on one hand temperature and two indoor ambient temperatures; and the fourth layer of temperature decision condition includes: decision conditions based on five hand temperatures. The system includes a fifth layer of temperature decision conditions based on the stated indoor ambient temperature, a sixth layer of temperature decision conditions based on the stated hand temperatures and nine indoor ambient temperatures, a seventh layer of temperature decision conditions based on the stated hand temperatures and eight indoor ambient temperatures, and an eighth layer of temperature decision conditions based on the stated hand temperatures and nine indoor ambient temperatures. The system then determines the target user's temperature and cold sensation state based on the output value of the individual user's temperature and cold sensation decision tree model; adjusts the currently set target temperature according to the temperature and cold sensation state; and controls the air conditioner's operation based on the adjusted target temperature.

[0009] The air conditioner and its control method disclosed herein adjust the target temperature by employing a user-specific temperature and coldness decision tree model established based on big data and artificial intelligence technologies. This compensates for the shortcomings of the PMV (Predicted Mean Vote) comfort prediction model based on the general population, which weakens individual differences. Furthermore, it considers not only the user's hand temperature to experience their current temperature and coldness, but also the indoor ambient temperature, which affects the user's temperature and coldness experience. Therefore, the air conditioner inputs the hand temperature and indoor ambient temperature into the user-specific temperature and coldness decision tree model, thereby satisfying the temperature and coldness comfort of the target user, improving the personalized and differentiated needs of the user, and enhancing the comfort of the air conditioner.

[0010] Additional aspects and advantages of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this disclosure. Attached Figure Description

[0029] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, various details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0030] In this disclosure, the air conditioner performs a refrigeration cycle using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, supplying refrigerant to conditioned and heat-exchanged air. Figure 1 The diagram shown is a schematic diagram of the refrigeration cycle system of an air conditioner according to an embodiment of the present disclosure.

[0031] The compressor compresses refrigerant gas under high temperature and pressure 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.

[0032] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0033] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0034] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0035] To improve individual user comfort, this disclosure improves the performance of air conditioners and proposes an air conditioner and its control method that can meet the comfort needs of different individual users.

[0036] The following is for reference. Figures 2-17 An air conditioner according to an embodiment of the present disclosure is described.

[0037] 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.

[0038] The human body temperature detection device 10 is used to detect the hand temperature of the target user. In this embodiment, the human body temperature detection device 10 can be an infrared detection device, such as an infrared camera, to collect the temperature of the exposed parts of the target user, such as the hand temperature.

[0039] 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.

[0040] 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.

[0041] The following is an explanation of the individual user's temperature and coldness decision tree model.

[0042] In this embodiment, the individual user temperature and coldness decision tree model is a temperature and coldness prediction and identification model established based on human physiological parameters and environmental parameters using big data artificial intelligence technology to address the different thermal comfort needs of individual users. It learns the temperature and coldness change patterns of individual users, accurately identifies individual user thermal comfort needs, and performs personalized thermal comfort control to meet the differentiated and personalized thermal comfort control requirements of different individual users.

[0043] like Figure 3 The diagram illustrates a modeling process for establishing a user's individual temperature and coldness decision tree model using big data-based artificial intelligence technology, according to an embodiment of this disclosure.

[0044] Specifically, firstly, data collection can be carried out. Training data and tests can be collected in the laboratory using infrared equipment. For example, skin temperature and hand temperature of different groups, including the elderly, children, men and women, can be collected in different seasons. It is understandable that different groups can exhibit different human thermal sensation, metabolic rate, clothing thermal resistance, and environmental conditions in different seasons.

[0045] Secondly, model training is performed, and the training data is used for model selection, debugging, and optimization. Specifically, the training data is input into the initial model, and then the initial model is debugged and optimized based on the model's output results, so that the model's output data can be closer to the real situation.

[0046] Next, generate the model. Specifically, select the optimal model output from the training.

[0047] Finally, the model is used to make predictions based on the test data to obtain the model accuracy. For example, in the embodiments of this disclosure, the accuracy of the user individual temperature and coldness decision tree model can reach more than 80%.

[0048] In this embodiment, a user-specific temperature and coldness decision tree model that achieves the expected result can be pre-stored in the storage unit of the controller 30 of the air conditioner 1. The user-specific temperature and coldness decision tree model of this embodiment is configured with at least eight layers of temperature decision condition sets, which constitute multiple temperature determination branches. The first layer of temperature decision condition sets includes: decision conditions based on hand temperature; the second layer includes: decision conditions based on hand temperature and indoor ambient temperature; the third layer includes: decision conditions based on one hand temperature and two indoor ambient temperatures; the fourth layer includes: decision conditions based on five hand temperatures and one indoor ambient temperature; the fifth layer includes: decision conditions based on eight hand temperatures and four indoor ambient temperatures; the sixth layer includes: decision conditions based on six hand temperatures and nine indoor ambient temperatures; the seventh layer includes: decision conditions based on eleven hand temperatures and eight indoor ambient temperatures; and the eighth layer includes: decision conditions based on seven hand temperatures and nine indoor ambient temperatures. For example, Figure 4-10The diagrams shown are partial illustrations of a user-specific temperature / coldness decision tree model according to an embodiment of this disclosure. The model resembles a tree, with a left branch representing a true judgment and a right branch representing a false judgment. A series of judgments are performed until no further branches occur, at which point the final result is output. In some embodiments, the user-specific temperature / coldness decision tree model may include at least eight layers of temperature decision conditions and seventy-five temperature decision branches composed of these eight layers. Each temperature decision branch may have the same or different temperature decision conditions. Each branch of the model performs an independent temperature / coldness judgment, and each temperature decision branch can output a corresponding temperature / coldness prediction result. The final value of the temperature / coldness judgment, i.e., the output value of the user-specific temperature / coldness decision tree model, can be -1 (slightly cold), 0 (neutral), or 1 (slightly hot). Therefore, the user's current temperature / coldness state can be determined based on the output value of the user-specific temperature / coldness decision tree model.

[0049] Understandable, Figure 4-10 The user-specific temperature / cold sensation decision tree model shown is merely an example of one model in this disclosure. Other suitable decision tree models can also be adopted based on the results of model training, optimization, and testing.

[0050] Furthermore, in this embodiment, not only is the user's hand temperature considered as reflecting their current temperature sensation, but also the indoor ambient temperature, which affects the user's temperature experience. Therefore, considering both hand temperature and indoor ambient temperature, the air conditioner 1 inputs the hand temperature and indoor ambient temperature into the user's individual temperature sensation decision tree model. Based on the output value of the user's individual temperature sensation decision tree model, the air conditioner determines the target user's temperature sensation state, adjusts the currently set target temperature according to the temperature sensation state, and controls the operation of the air conditioner based on the adjusted target temperature. This satisfies the target user's individual temperature sensation comfort, improves the user's personalized and differentiated needs, and enhances the comfort of the air conditioner.

[0051] The current target temperature can be the temperature set by the user through the air conditioner's control terminal, such as a remote control, wired controller, or air conditioner APP installed on a mobile smart device, when the air conditioner is started, or the current temperature of the air conditioner when the user starts the user's individual comfort mode. No specific limitation is made here.

[0052] The air conditioner 1 of this disclosure adjusts the target temperature by using a user-specific temperature and cold sensation decision tree model established based on big data and artificial intelligence technology. This can compensate for the shortcomings of the PMV predictive comfort model based on the general population, which weakens individual differences. As a result, the air conditioner 1 not only meets the comfort needs of the general population, but also realizes the personalized comfort needs of individual family users.

[0053] Specifically, when air conditioner 1 operates in the user's individual comfort mode, for example, when there is only one person in the room, the human body temperature detection device 10 collects the target user's hand temperature in real time, the indoor temperature detection device 20 collects the indoor ambient temperature in real time, and the controller 30 receives the temperature data and calls the user's individual temperature and coldness decision tree model. It compares the hand temperature and indoor ambient temperature with the temperature decision conditions at each level of the multiple temperature decision branches in the user's individual temperature and coldness decision tree model to determine the target temperature decision branch. Each temperature decision branch in the model executes independently, obtaining the output value of the target temperature decision branch corresponding to the user's individual temperature and coldness decision tree model. The temperature and coldness state corresponding to the output value is taken as the target user's temperature and coldness state. For example, an output value of -1 indicates the user feels cold; an output value of 0 indicates the user is neither hot nor cold (neutral); and an output value of 1 indicates the user feels hot. Then, the target temperature is adjusted according to the user's current temperature and coldness state, and the compressor frequency, fan speed, and air guide direction of the air conditioner are adjusted according to the adjusted target temperature, thereby improving user comfort and meeting the user's personalized comfort needs.

[0054] The following reference Figure 4-10 The user's individual temperature and coldness decision tree model is shown to illustrate the process by which the controller 30 identifies the user's temperature and coldness state.

[0055] After the user activates the individual comfort model, the controller 30 obtains the hand temperature using T. 手部 Indoor ambient temperature is represented by T. 室内 Indicate, and will T 手部 and T 室内 Input user's individual temperature / coolness decision tree model, for example Figure 4-6 The tree model compares the temperature value with the temperature decision conditions in the model. Each temperature decision branch is executed independently until the model's output value is obtained, and the user's current temperature feeling state is determined based on the output value.

[0056] like Figure 4-10 As shown, each temperature determination branch is explained. In this embodiment, the user-specific temperature and coldness decision tree model uses hand temperature as the first-level temperature decision condition, hand temperature and indoor ambient temperature as the second-level temperature decision conditions, and further branches use different temperature determination conditions for identification. Specifically, in this embodiment, the hand temperature and indoor ambient temperature have different values ​​under different decision conditions in the user-specific temperature and coldness decision tree model. For example, the threshold values ​​for each decision condition of hand temperature are between 29.75℃ and 36.65℃, and the threshold values ​​for each decision condition of indoor ambient temperature are between 22.10℃ and 30.85℃.

That is, if the user currently feels that the temperature is too high, then the currently set target temperature is lowered to reduce the user's perceived temperature and improve comfort.

[0125] In some embodiments, such as Figure 10 As shown, air conditioner 30 is also configured to: if T is not met 室内 ≤T 室内设定31 Then, further determine whether the hand temperature T is met. 手部 ≤T 手部设定38 , among which, T 手部设定38 <T 手部设定34 If T is satisfied 手部 ≤T 手部设定38 If the target temperature decision branch is determined to be the 70th temperature decision branch, and the output value of the corresponding 70th temperature decision branch of 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, if the user currently feels that the temperature is too high, then the currently set target temperature will be lowered to reduce the user's perceived temperature and improve comfort.

[0127] If T is not satisfied 手部 ≤T 手部设定39Then, it is further determined whether the indoor ambient temperature T is met. 室内 ≤T 室内设定33 , among which, T 室内设定31 <T 室内设定33 If T is satisfied 室内 ≤T 室内设定33 Then, further determine whether the hand temperature T is met. 手部 ≤T 手部设定40 , among which, T 手部设定39 <T 手部设定40 If T is satisfied 手部 ≤T 手部设定40 If the target temperature decision branch is determined to be the 72nd temperature decision branch, and the output value of the 72nd temperature decision branch corresponding to the user's individual temperature and coldness decision tree model is obtained as a "hot" output value (e.g., an output of 1), then the target user's temperature and coldness state is "hot". That is, if the user currently feels the temperature is too high, then the currently set target temperature is lowered to reduce the user's perceived temperature and improve comfort.

[0128] If T is not satisfied 手部 ≤T 手部设定40 If the target temperature decision branch is determined to be the 73rd temperature decision branch, and the output value of the 73rd temperature decision branch corresponding to the user's individual temperature and cold perception decision tree model is obtained as a "hot" output value (e.g., an output of 1), then the target user's temperature and cold perception state is "hot". That is, if the user currently feels the temperature is too high, the currently set target temperature will be lowered to reduce the user's perceived temperature and improve comfort.

[0129] The above are examples of methods used. Figure 4-10 The process of the user's individual temperature and coldness decision tree model in determining the user's temperature and coldness status is shown above. It can be understood that the user's individual temperature and coldness recognition process in other models is similar to the above process, but the model's hierarchy, temperature determination branches, and temperature decision conditions for each branch and each node are different from the model disclosed in this publication.

[0130] Furthermore, in some embodiments, to improve the accuracy of identifying a user's current temperature sensitivity based on the aforementioned user-specific temperature sensitivity decision tree model, the controller 30 is further configured to periodically input hand temperature and indoor ambient temperature into the user-specific temperature sensitivity decision tree model to obtain a preset number of output values. These preset number of output values ​​are then statistically analyzed and categorized, and the temperature sensitivity state corresponding to the output value in the category containing the most output values ​​is taken as the target user's temperature sensitivity state. This improves the accuracy of user-specific temperature sensitivity identification, allowing the model to further optimize itself through machine learning, thereby further improving the accuracy of the identification results and creating a virtuous cycle.

[0131] In some embodiments, the controller 30 is further configured to: increase the indoor fan speed of the air conditioner 1 if the target user's perceived temperature is too cold after a preset number of consecutive tests when the air conditioner 1 is in heating mode; decrease the indoor fan speed of the air conditioner 1 if the target user's perceived temperature is too hot after a preset number of consecutive tests when the air conditioner 1 is in heating mode; decrease the indoor fan speed of the air conditioner 1 if the target user's perceived temperature is too cold after a preset number of consecutive tests when the air conditioner 1 is in cooling mode; and increase the indoor fan speed of the air conditioner 1 if the target user's perceived temperature is too hot after a preset number of consecutive tests when the air conditioner 1 is in cooling mode. For example, the controller 30 uses a user's individual temperature perception decision tree model to perform three independent temperature perception judgment values ​​(-1, 0, 1) respectively, and then performs statistical analysis. The temperature perception value with the most statistically significant values ​​is the final output value for temperature perception judgment.

[0132] For example, such as Figure 11 The diagram shows a flowchart of the overall operation logic of the comfort control of an air conditioner according to an embodiment of this disclosure. If the controller 30 outputs a "hot" (1) result based on the user's individual temperature and coldness perception decision tree model, the controller 30 sends a cooling signal, lowering the set temperature by 1°C. If the controller 30 outputs a "cold" (-1) result based on the user's individual temperature and coldness perception decision tree model, the controller 30 sends a heating signal, raising the set temperature by 1°C. If the controller 30 outputs a "neutral" (0) result based on the user's individual temperature and coldness perception decision tree model, the controller 30 maintains the existing setting. Each judgment cycle is based on the air conditioner feedback time. If the temperature and coldness perception prediction is "cold" (or "hot") for three consecutive cycles, it is considered that the user's individual temperature and coldness perception is strong, and the fan speed needs to be increased by one level; otherwise, the air conditioner fan speed remains unchanged.

[0133] In some embodiments, the second aspect of this disclosure also provides a control method for an air conditioner, which can be executed by the air conditioner's controller. The control method includes: receiving the hand temperature of a target user and the indoor ambient temperature; inputting the hand temperature and the indoor ambient temperature into a user's individual temperature and coldness perception decision tree model, wherein the user's individual temperature and coldness perception decision tree model is configured with at least eight layers of temperature decision condition sets, and the at least eight 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 hand temperature, the second layer of temperature decision condition set includes: decision conditions based on hand temperature and indoor ambient temperature, and the third layer of temperature decision condition set includes: decision conditions based on one hand temperature and two indoor ambient temperatures. The system has four temperature decision-making conditions: the fourth level includes five hand temperatures and one indoor ambient temperature; the fifth level includes eight hand temperatures and four indoor ambient temperatures; the sixth level includes six hand temperatures and nine indoor ambient temperatures; the seventh level includes eleven hand temperatures and eight indoor ambient temperatures; and the eighth level includes seven hand temperatures and nine indoor ambient temperatures. The system determines the target user's temperature and cold perception state based on the output value of the individual user's temperature and cold perception decision tree model; adjusts the currently set target temperature according to the temperature and cold perception state; and controls the air conditioner's operation based on the adjusted target temperature.

[0134] Of course, in the embodiments, the control method of the air conditioner in this disclosure may also include other contents executed by the controller of the air conditioner, such as how to obtain the hand 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. Referring to the above description, it will not be repeated here.

[0135] In summary, this invention addresses the diverse thermal comfort needs of individual users by utilizing big data-based artificial intelligence to establish a user-specific temperature and cold sensation decision tree model. This model learns from the patterns of temperature and cold sensation changes, accurately identifies individual user thermal comfort needs, and enables personalized thermal comfort control, thus meeting the differentiated and personalized comfort control requirements of different users. Simultaneously, it overcomes the shortcomings of general population-based PMV predictive comfort models, which weaken individual differences, enabling air conditioner 1 to not only meet the comfort needs of the general population but also fulfill the personalized comfort needs of individual households.

[0136] In the embodiments described above, for individual users, such as when there is only one user indoors, the user selects the individual comfort mode. Alternatively, if the air conditioner 1 detects that there is only one user indoors, it automatically activates the individual comfort mode. In this case, the air conditioner 1 can execute the individual comfort mode as described above to improve the individual user's comfort. However, when there are multiple people indoors, the air conditioner 1 will run a TMS (Therma and Humidity Management System) comfort mode based on a PMV predictive comfort model, which is suitable for the general population.

[0137] In some embodiments, when the air conditioner 1 is running automatically, it can activate the indoor user detection function to detect how many people are in the room. If there is only one person, it can automatically activate the individual user comfort mode, and if there are multiple people, it can run the TMS comfort mode.

[0138] For individual user comfort modes, such as Figure 12 As shown, when the air conditioner 1 is running, it activates the user's individual comfort mode, collects indoor temperature and humidity, 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 hand temperature and indoor ambient temperature and calls the user's individual temperature and coldness decision tree model. Then, it adjusts the target temperature according to the model output value, and then controls the air conditioner to run automatically based on the adjusted target temperature to meet the individual user's personalized comfort needs and improve user comfort.

[0139] The following section explains the TMS comfort mode based on the PMV predictive comfort model.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] Table 1 below shows the names and meanings of the various symbols in the TMS Comfort Mode description.

[0144] Table 1

[0145]

[0146]

[0147] In some embodiments, when running TMS comfort mode, the air conditioner uses its own sensors to detect the outer ring temperature (Tout), inner ring temperature (Tin), and indoor relative humidity (Rh). Based on the acquired Tout, it enters the corresponding temperature zone and determines the next specific operating mode (cooling / heating / ventilation). Every 2 hours, a new operating temperature zone is determined based on the outer ring temperature (Tout). If it remains in the original operating temperature zone, it continues to maintain the original mode and stage of operation; if it is in a new temperature zone, it combines the inner ring temperature (Tin) and indoor relative humidity (Rh) of the new temperature zone to interrupt the original operating mode and enter the new specific sub-mode. In the event of an indoor sensor malfunction or overflow, or in the absence of a humidity sensor, Rh defaults to 65%.

[0148] In some embodiments, addressing is performed based on a 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, and ventilation. Then, addressing is performed according to the rules of different modes, as follows.

[0152]

[0153]

[0154] In some embodiments, when the air conditioner is operating in cooling mode, refer to Figure 13 As shown, the addressing process is as follows:

[0155] According to Table 3, the baseline comfort table, if Rh < 30% (the lower limit of the comfort humidity in the comfort table), then Ts is the lowest temperature corresponding to Rh 30% in the comfort table. 初 (Ts_ 初 =24.5℃); If Rh > 65% (the upper limit of the comfort humidity table), then the lowest temperature corresponding to Rh 65% in the comfort table is Ts_ 初 (Ts_ 初 =23.5℃); If 65% ≥ Rh ≥ 30% (comfort humidity upper and lower limits of the comfort table), the lowest temperature corresponding to the closest humidity in the comfort table shall be Ts_ 初 (If Rh = 43%, and the closest humidity level on the comfort scale is Rh = 45%, then the lowest temperature corresponding to Rh = 45% is Ts_) 初 =24℃). The average of the sum of the upper limit of comfortable humidity (26.5℃) and the lower limit of comfortable humidity (24℃) corresponding to Rh=50% in the comfort table (25.25℃) is taken as Ts_ 舒 The default temperature is 25.5℃.

[0156] In some embodiments, when the air conditioner is operating in heating mode, refer to Figure 14 As shown, the addressing process is as follows:

[0157] According to Table 3, the baseline comfort table, if Rh < 30% (the lower limit of the comfort humidity in the comfort table), then Ts is the highest temperature corresponding to Rh 30% in the comfort table. 初 (Ts_ 初 =27℃); If Rh > 65% (the upper limit of the comfort humidity table), then 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), the lowest temperature corresponding to the humidity closest in the comfort table is Ts_ 初 (For example, if Rh = 43%, the humidity closest 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 value (26.5 °C) and the lower limit value (24 °C) of the comfortable humidity corresponding to Rh = 50% in the comfort table is taken as Ts_comfort, and the default is 25.5 °C.

[0158] In some embodiments, when the air conditioner operates in the air supply mode, the air conditioner does not perform addressing.

When E ≤ -0.5°C and it lasts for 30 minutes (starting from the time when Ts(n + 1) = Ts_comfort + T_compensation), enter the dehumidification healthy and comfortable stage.

[0164] Dehumidification healthy and comfortable stage: Ts(1) = Ts_ <00oo600>+T 补 + 0.5°C, increasing by 0.5°C every 5 minutes, that is, Ts(n + 1) = Ts(n) + 0.5°C, until Ts(n + 1) = Ts_ 节 +T 补 , where n is a natural number greater than or equal to 1. / / Use a recursive increasing function to prevent the compressor from stopping when the set temperature is reached due to a large temperature change during stage conversion.

[0173]

[0174] In some embodiments, based on the humidity control and moisturizing theory that "as indoor humidity increases, the peak of air conditioner dehumidification capacity tends to gradually shift towards the high fan speed side of the indoor unit, and the critical points for dry and wet conditions are different at different fan speeds; the higher the fan speed, the higher the inlet relative humidity is required to enter the wet condition; the lower the fan speed, the lower the inlet relative humidity is required to enter the wet condition" (as shown in Table 5), Figure 16 This paper proposes a method for controlling the comfort of indoor fans, which effectively controls and maintains the relative humidity of the indoor environment within a range that is comfortable for the human body.

[0177] Based on the aforementioned humidity control and moisturizing theories, a method for controlling the comfort of indoor fans is proposed, which effectively controls and maintains the relative humidity of the indoor environment within a range that is comfortable for the human body. (Refer to...) Figure 17 This invention describes an indoor fan comfort control method when the air conditioner is in cooling mode, according to an embodiment of the present disclosure.

[0178] Step S11: The air conditioner turns on its TMS function. Step S12: The indoor ambient temperature Tin, outdoor ambient temperature Tout, indoor relative humidity Rh, and indoor instantaneous sampled relative humidity Rhi are acquired.

[0179] Step S13: Determine whether the air conditioner enters cooling or dehumidification mode based on the indoor ambient temperature Tin, the outdoor ambient temperature Tout, and the indoor relative humidity Rh.

[0180] Step S14: The air conditioner enters cooling mode. Step S15: Control the indoor fan speed.

[0181] Step S16: Determine whether the set temperature difference E is greater than the first set temperature, for example, 2°C. If yes, proceed to step S17; otherwise, proceed to step S18.

[0182] Step S17: Control the indoor fan to operate at the first fan speed. Step S18: Control the indoor fan to operate at the second fan speed. Step S19: Determine whether the set temperature difference E is less than or equal to the first set temperature, for example, 2°C. If yes, proceed to step S18; if no, proceed to step S17.

[0183] S20. Determine whether the first temperature difference is greater than or equal to -2℃ and less than or equal to 2℃ within a preset time. If yes, proceed to step S21; otherwise, proceed to step S18.

[0184] Step S21: Determine whether the second temperature difference is greater than or equal to -6 and less than 6. If yes, proceed to step 20; otherwise, proceed to step S22.

[0185] Step S22: Determine whether the second temperature difference is greater than 6. If yes, proceed to step S23; otherwise, proceed to step S24.

[0188] Step S25: Control the indoor fan to run at the fourth fan speed.

[0189] By using the steps S11-S25 above, the energy consumption of the air conditioner can be reduced while ensuring user comfort.

[0190] The TMS comfort mode based on the PMV model of this disclosure has been described above.

[0191] In summary, the air conditioner of this disclosure embodiment can be set to a user-specific comfort mode and a TMS comfort mode. Since the PMV model is an average thermal sensation prediction model based on a general population, it weakens the influence of individual user differences. To meet the personalized and differentiated thermal comfort needs of household air conditioners, especially individual family users, a user-specific temperature and cold sensation decision tree model is established using big data-based artificial intelligence technology. This model learns the patterns of temperature and cold sensation changes, accurately identifies individual user thermal comfort needs, and performs personalized thermal comfort control, satisfying the differentiated and personalized comfort control requirements of different users. This also compensates for the shortcomings of the PMV predictive comfort model based on a general population, which weakens individual differences, enabling the air conditioner to not only meet the comfort needs of the general population but also realize the personalized comfort needs of individual family users.

[0192] The user-specific temperature / coolness decision tree model in this disclosure is based on machine learning methods. Its accuracy largely depends on the amount of data used in training. Therefore, in practical applications, its accuracy will improve as the amount of data increases. Ideally, the temperature / coolness prediction model based on skin temperature can achieve fully automated control without human intervention in parameter adjustment.

[0193] Furthermore, terminology is used in the above technical description to provide a thorough understanding of the described embodiments. However, excessive detail is not required to implement the described embodiments. Therefore, the above description of the embodiments is presented for illustrative and descriptive purposes.
