Detailed Implementation

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following description, with reference to the accompanying drawings, describes an air conditioner and its control method, apparatus, storage medium, and controller according to embodiments of the present invention.

[0028] Figure 1 This is a flowchart of an air conditioner control method according to an embodiment of the present invention.

[0029] like Figure 1 As shown, the control method for an air conditioner according to an embodiment of the present invention includes the following steps: S101, obtain the human body location, and determine whether the human body is within the air supply range of the air conditioner based on the human body location.

[0030] Specifically, when the air conditioner is turned on, the indoor fan runs at a preset speed, and the air conditioner automatically acquires the location of the person and determines whether the person is within the airflow range of the air conditioner. It should be noted that the air conditioner can be equipped with infrared sensors and distance sensors, which can be used to acquire the location of the person in real time.

[0031] S102, if the human body is not within the air supply range, the first perceived temperature is calculated based on the indoor humidity and the return air temperature of the air conditioner, and the air supply mode of the air conditioner is controlled based on the first perceived temperature.

[0032] Specifically, after the air conditioner is turned on, the indoor humidity and the return air temperature of the air conditioner can be obtained in real time through the corresponding humidity sensor and temperature sensor. If the human body is detected to be outside the air supply range, the first perceived temperature is calculated based on the obtained indoor humidity and the return air temperature of the air conditioner, and the air supply mode of the air conditioner is controlled according to the first perceived temperature.

[0033] It should be noted that the aforementioned first perceived temperature can be calculated using the following formula: , Where AT is the first perceived temperature (°C), E is the vapor pressure, V is the wind speed at the human body (m / s), RH is the indoor humidity, and e is the natural logarithm. Since the human body is not within the air supply range, T here is taken as the temperature at the air conditioner's return air vent. V is 0.

[0034] In some embodiments of the present invention, the air supply mode of the air conditioner is controlled according to a first perceived temperature, such as... Figure 2 As shown, it includes: S201, calculate the first difference between the first perceived temperature and the preset perceived temperature.

[0035] It should be noted that the preset perceived temperature mentioned above refers to the temperature at which the human body feels most comfortable, denoted as . Furthermore, the preset perceived temperature in this embodiment is not fixed and can be set according to actual conditions. For example, the most comfortable perceived temperature for the human body in summer is between 18°C ​​and 24°C. 22℃ is acceptable.

[0036] S202, if the absolute value of the first difference is less than the first threshold, then control the air conditioner to operate in economy mode.

[0037] Specifically, if If the indoor temperature is deemed suitable, the air conditioner will be switched to economy mode to save electricity. Here, AT represents the first perceived temperature. R is the preset perceived temperature, and R is the first threshold.

[0038] S203, if the absolute value of the first difference is greater than or equal to the first threshold, then increase the fan speed of the air conditioner, lower the air supply temperature when the air conditioner is cooling, and increase the air supply temperature when the air conditioner is heating.

[0039] Specifically, if If the indoor temperature is too high or too low, the air conditioner's fan speed needs to be increased, and the air supply temperature should be lowered when the air conditioner is in cooling mode and raised when the air conditioner is in heating mode.

[0040] Therefore, by comparing the difference between the first perceived temperature and the preset perceived temperature (i.e., the perceived temperature when the human body is most comfortable) with the first threshold, it can be determined whether the air supply temperature and fan speed of the air conditioner are suitable for the user. Based on the judgment result, the air supply mode of the air conditioner can be adjusted to make the user feel more comfortable in the air supply environment and improve the user experience.

[0041] S103 If the human body is within the air supply range, the second perceived temperature is calculated based on the human body's position, indoor humidity, return air temperature, air outlet temperature of the air conditioner, and air outlet wind speed, and the air supply mode of the air conditioner is controlled based on the second perceived temperature.

[0042] In some embodiments of the present invention, such as Figure 3 As shown, the second perceived temperature is calculated based on the human body position, indoor humidity, return air vent temperature, air conditioner outlet temperature, and outlet wind speed. This may include: S301, determine the distance between the human body and the air conditioner based on the human body's position.

[0043] Specifically, when a human body is detected within the air supply range, the air outlet of the air conditioner is adjusted so that the airflow direction is directly facing the human body, thereby determining the straight-line distance S between the human body and the air conditioner based on the human body's position.

[0044] S302 calculates the wind speed at the human body based on the distance and the wind speed at the air outlet, and calculates the temperature at the human body based on the distance, the temperature at the return air outlet, and the temperature at the air outlet.

[0045] Specifically, the air velocity at the air outlet, the temperature at the return air outlet, and the air outlet temperature of the air conditioner are obtained, and the air velocity at the human body is calculated using the following formula: ,in, V is the air velocity at the air outlet of the air conditioner, V is the air velocity at the human body (m / s), and S is the distance between the human body and the air conditioner (m). The axial velocity constant is The area of ​​the air outlet (m²) 2 Then, the temperature at the human body is calculated using the following formula: ,in, The air outlet temperature of the air conditioner (°C). T represents the return air temperature of the air conditioner (°C), and T represents the temperature at the human body (°C). Here is the axial temperature constant. The area of ​​the air outlet (m²) 2 ).

[0046] Generally speaking, for grille air vents and rectangular air vents, the aforementioned axial velocity constant... A value of 4.1 can be taken, which is the axial temperature constant mentioned above. 1.7 is acceptable.

[0047] S303, calculate the second perceived temperature based on the wind speed at the human body, the temperature at the human body, and the indoor humidity.

[0048] It should be noted that the aforementioned second perceived temperature can be calculated using the following formula: , Where AT is the second perceived temperature (°C), E is the water vapor pressure, T is the temperature at the human body (°C), V is the wind speed at the human body (m / s), RH is the indoor humidity, and e is the natural logarithm.

[0049] In some embodiments of the present invention, the air supply mode of the air conditioner is controlled according to the second perceived temperature, such as... Figure 4 As shown, it includes: S401, calculate the second difference between the second perceived temperature and the preset perceived temperature.

[0050] S402, if the absolute value of the second difference is greater than or equal to the second threshold, then increase the fan speed of the air conditioner, lower the supply air temperature when the air conditioner is cooling, and increase the supply air temperature when the air conditioner is heating.

[0051] Specifically, when the absolute value of the second difference is greater than or equal to the second threshold, i.e. If the indoor temperature is too high or too low, the air conditioner's fan speed needs to be increased, and the supply air temperature should be lowered when the air conditioner is cooling and raised when the air conditioner is heating. Here, AT represents the second perceived temperature. R is the preset perceived temperature, and R is the second threshold.

[0052] S403, if the absolute value of the second difference is less than the second threshold, the expected average thermal sensation index and the wind sensation index at the human body are calculated based on the temperature at the human body and the wind speed at the human body, and the air supply mode of the air conditioner is controlled based on the expected average thermal sensation index and the wind sensation index at the human body.

[0053] Specifically, when the absolute value of the second difference is less than the second threshold, i.e. If the indoor temperature is within a certain range, it is considered to be suitable. Based on this, comfort is more important for users. Therefore, the air supply method can be controlled by predicting the average thermal sensation index and the airflow sensation index at the human body, thereby improving user comfort.

[0054] Furthermore, the air supply mode of the air conditioner is controlled based on the expected average thermal sensation index and the airflow sensation index at the human body, including: if the expected average thermal sensation index at the human body is greater than a first preset value and less than a second preset value, the air conditioner is controlled to maintain the current air supply mode, where the first preset value is less than the second preset value; if the expected average thermal sensation index at the human body is less than or equal to the first preset value, or if the expected average thermal sensation index at the human body is greater than or equal to the second preset value, the air supply mode of the air conditioner is controlled based on the airflow sensation index at the human body.

[0055] Furthermore, when the expected average thermal sensation index at the human body is less than or equal to the first preset value, the air supply mode of the air conditioner is controlled according to the air blowing sensation index at the human body, including: if the air blowing sensation index at the human body is greater than the third preset value, the fan speed of the air conditioner is reduced; if the air blowing sensation index at the human body is less than or equal to the third preset value, the air supply temperature is increased when the air conditioner is cooling and decreased when the air conditioner is heating.

[0056] Furthermore, when the expected average thermal sensation index at the human body is greater than or equal to the second preset value, the air supply mode of the air conditioner is controlled according to the air blowing sensation index at the human body. This may include: if the air blowing sensation index at the human body is greater than the third preset value, the air supply temperature is lowered when the air conditioner is cooling and the air supply temperature is raised when the air conditioner is heating; if the air blowing sensation index at the human body is less than or equal to the third preset value, the fan speed of the air conditioner is increased.

[0057] It should be noted that the above-mentioned expected average thermal sensation index for the human body can be calculated using the following formula: Where PWV is the expected average thermal sensation index at the human body, M is the metabolic rate, and W is the heat consumed by external work, which is negligible for most activities. For water vapor partial pressure, For air temperature, It is the ratio of the body surface area when clothed to the body surface area when naked. For the surface temperature of the garment, The mean radiation temperature. The convective heat transfer coefficient is... For the thermal resistance of clothing, Let M be the air velocity. For example, the metabolic rate M can be taken as... W is 0. Take e, , , All are taken from the human body temperature T. The value can be selected based on the season; for example, in summer... Take in winter , Take the wind speed V at the human body location.

[0058] The above formula takes into account information on the expected average thermal perception index (PMV) of the human body from multiple aspects such as clothing, human characteristics, and environmental parameters, which improves the accuracy of the expected average thermal perception index (PMV) of the human body. This allows for a more objective reflection of the comfort level of the human surface in the current environment, such as hot, warm, slightly warm, moderate, cool, and cold, thereby further improving the precision of the air supply mode control of the air conditioner.

[0059] In addition, the aforementioned airflow sensation index at the human body can be calculated using the following formula: Where DR is the wind feel index at the human body, T is the temperature at the human body, and V is the wind speed at the human body. For turbulence intensity, In cases where the outcome is unknown, a 40% threshold can be taken.

[0060] Therefore, based on the second difference and second threshold between the second perceived temperature and the preset perceived temperature, it is first determined whether the indoor temperature is suitable. After adjusting the air conditioner's air supply mode to make the indoor temperature suitable, user comfort is considered. The calculated airflow index DR is used to measure the degree to which a person feels a breeze, such as no breeze, a breeze, or a noticeable breeze. Combined with the predicted average thermal perception index PMV at the human body, the two indicators are combined to reflect the user's comfort in the current environment, thereby further improving the accuracy of the air conditioner's air supply mode control and ensuring that the user is in an optimal comfort state.

[0061] To better understand the air conditioner control method of the embodiments of the present invention, please refer to... Figure 5 Taking the air conditioner in cooling mode as an example, the control method of the air conditioner is described below.

[0062] like Figure 5 As shown, the air conditioner is turned on, the fan starts running, and it automatically acquires the human body's position, the air conditioner's outlet temperature, the air conditioner's return air temperature, and the indoor humidity.

[0063] First, the system detects whether the person is within the air conditioning's airflow range based on their location. If the person is not detected within the airflow range, the first perceived temperature is calculated using a formula, and is represented as... The absolute value of the difference between the first perceived temperature and the preset perceived temperature, i.e., the absolute value of the first difference, is compared with a first threshold. It should be noted that in this example, the first threshold can be 5. If the absolute value of the first difference is less than 5, the eco mode is activated and runs continuously; otherwise, it indicates that the indoor temperature is too high, so the air conditioner's fan speed is increased and the air supply temperature is decreased to cool the room quickly.

[0064] If a human body is detected within the air supply range, the air conditioner's vent is adjusted so that the airflow is directed directly at the human body. The airflow speed at the vent and the straight-line distance between the human body and the air conditioner are obtained. The airflow speed at the human body, the temperature at the human body, and the second perceived temperature are calculated using formulas. The airflow speed at the human body is represented as... The temperature of the human body is characterized as The second perceived temperature is characterized as .

[0065] Furthermore, based on the absolute value of the difference between the second perceived temperature and the preset perceived temperature (i.e., the absolute value of the second difference), compared with the first threshold, if the absolute value of the second difference is greater than or equal to 5, it is determined that the indoor temperature is too high, requiring rapid cooling, lowering the air supply temperature, and increasing the fan speed; if the absolute value of the second difference is less than 5, the expected average thermal sensation index and the draft sensation index at the human body are calculated according to the formula. The expected average thermal sensation index at the human body is represented as... The wind-blowing index is characterized as .

[0066] Furthermore, based on the calculated PMV value, in this example, the PMV value between -0.5 and 0.5 represents the comfortable range for the human body. Therefore, in this embodiment of the invention, the first preset value can be -0.5, and the second preset value can be 0.5. Thus, when the PMV value is greater than -0.5 and less than 0.5, it is determined to be comfortable for the human body, and the current fan speed and air supply temperature of the air conditioner can be maintained. Conversely, when the PMV value is greater than or equal to 0.5, it is determined that the human body feels the room is too hot. It is understood that the reasons for feeling too hot are twofold: the fan speed is not high enough or the air supply temperature is not low enough.

[0067] Therefore, based on this, it is necessary to further judge according to the airflow sensation index (DR value). In this example, a DR value of 15 is defined as having a blowing sensation, so the third preset value in this embodiment of the invention can be 15. If the DR value is greater than 15, it is determined that there is a noticeable blowing sensation. Therefore, when the PMV value is greater than or equal to 0.5 and the DR value is greater than 15, it is determined that the supply air temperature is not low enough, causing people to feel that the room is too hot, and the supply air temperature needs to be lowered; when the PMV value is greater than or equal to 0.5 and the DR value is less than or equal to 15, it is determined that the fan speed is not high enough, causing people to feel that the room is too hot, and the fan speed needs to be increased. Similarly, when the PMV value is less than or equal to -0.5 and the DR value is greater than 15, it is determined that the fan speed is too high, causing people to feel that the room is too cold, and the fan speed needs to be lowered; when the PMV value is less than or equal to -0.5 and the DR value is less than or equal to 15, it is determined that the supply air temperature is too low, causing people to feel that the room is too cold, and the supply air temperature needs to be increased.

[0068] It should be noted that since users are not stationary indoors, in order to ensure that users can improve their comfort in any position, the above-mentioned air conditioner continuously acquires the user's position, the air conditioner's outlet temperature, the air conditioner's return air temperature, and the indoor humidity during operation. This allows the air supply mode to be controlled in real time according to changes in the user's position, thereby achieving the highest level of comfort.

[0069] In summary, the air conditioner control method of this embodiment first obtains the human body's position and determines whether the human body is within the air supply range of the air conditioner. If the human body is not within the air supply range, a first perceived temperature is calculated based on the indoor humidity and the return air temperature of the air conditioner, and the air supply mode of the air conditioner is controlled according to the first perceived temperature. If the human body is within the air supply range, a second perceived temperature is calculated based on the human body's position, indoor humidity, return air temperature, air outlet temperature of the air conditioner, and air outlet wind speed, and the air supply mode of the air conditioner is controlled according to the second perceived temperature. Therefore, this air conditioner control method can control the air supply mode of the air conditioner based on the human body's position and physical characteristics, improving user comfort without requiring user operation, making it more intelligent, and allowing for more precise adjustment of fan speed and air supply temperature. Moreover, during the operation of the air conditioner, the user's position, air outlet temperature, return air temperature, and indoor humidity are continuously acquired. This ensures that even if the human body's position changes, the air supply mode of the air conditioner is adjusted in real time accordingly, effectively improving user comfort.

[0070] Furthermore, the present invention proposes a computer-readable storage medium.

[0071] In this embodiment of the invention, a computer-readable storage medium stores a computer program thereon, which, when executed by a processor, implements the above-described air conditioner control method.

[0072] The computer-readable storage medium of this invention, when its computer program is executed by a processor, first acquires the human body's position and determines whether the human body is within the air supply range of the air conditioner. If the human body is not within the air supply range, a first perceived temperature is calculated based on the indoor humidity and the return air temperature of the air conditioner, and the air supply mode of the air conditioner is controlled based on the first perceived temperature. If the human body is within the air supply range, a second perceived temperature is calculated based on the human body's position, indoor humidity, return air temperature, air outlet temperature of the air conditioner, and air outlet wind speed, and the air supply mode of the air conditioner is controlled based on the second perceived temperature. Therefore, this air conditioner control method can control the air supply mode of the air conditioner based on the human body's position and physical characteristics, improving user comfort without requiring user operation, making it more intelligent, and allowing for more precise adjustment of fan speed and air supply temperature. Moreover, during the operation of the air conditioner, the user's position, air outlet temperature, return air temperature, and indoor humidity are continuously acquired. This ensures that even if the human body's position changes, the air supply mode of the air conditioner is adjusted in real time accordingly, effectively improving user comfort.

[0073] Furthermore, the present invention proposes a controller.

[0074] In this embodiment of the invention, the controller includes a memory, a processor, and a computer program stored in the memory. When the computer program is executed by the processor, it implements the control method of the air conditioner described above.

[0075] The controller in this embodiment of the invention, when its computer program is executed by a processor, first acquires the human body's position and determines whether the human body is within the air supply range of the air conditioner. If the human body is not within the air supply range, a first perceived temperature is calculated based on the indoor humidity and the air conditioner's return air temperature, and the air supply mode of the air conditioner is controlled according to the first perceived temperature. If the human body is within the air supply range, a second perceived temperature is calculated based on the human body's position, indoor humidity, return air temperature, air conditioner's outlet temperature, and outlet wind speed, and the air supply mode of the air conditioner is controlled according to the second perceived temperature. Therefore, this air conditioner control method can control the air supply mode of the air conditioner based on the human body's position and physical characteristics, improving user comfort without requiring user operation, making it more intelligent, and allowing for more precise adjustment of fan speed and air supply temperature. Moreover, during the operation of the air conditioner, the user's position, air conditioner outlet temperature, air conditioner return air temperature, and indoor humidity are continuously acquired. This ensures that even if the human body's position changes, the air supply mode of the air conditioner is adjusted in real time accordingly, effectively improving user comfort.

[0076] Furthermore, the present invention proposes a control device for an air conditioner.

[0077] Figure 6 This is a structural block diagram of the control device of an air conditioner according to an embodiment of the present invention.

[0078] like Figure 6 As shown, the control device 100 of the air conditioner includes an acquisition module 10, a judgment module 20 and a control module 30.

[0079] Specifically, the acquisition module 10 is used to acquire the human body position; the judgment module 20 is used to determine whether the human body is within the air supply range of the air conditioner based on the human body position; and the control module 30 is used to calculate the first perceived temperature based on the indoor humidity and the return air temperature of the air conditioner when the human body is not within the air supply range, and to control the air supply mode of the air conditioner based on the first perceived temperature; and to calculate the second perceived temperature based on the human body position, indoor humidity, return air temperature, air outlet temperature and air outlet wind speed of the air conditioner when the human body is within the air supply range, and to control the air supply mode of the air conditioner based on the second perceived temperature.

[0080] It should be noted that other specific embodiments of the control device for the air conditioner in this invention can be found in the control method for the air conditioner described above.

[0081] The control device for an air conditioner according to this invention can first acquire the location of a human body and determine whether the human body is within the air supply range of the air conditioner. If the human body is not within the air supply range, a first perceived temperature is calculated based on the indoor humidity and the return air temperature of the air conditioner, and the air supply mode of the air conditioner is controlled according to the first perceived temperature. If the human body is within the air supply range, a second perceived temperature is calculated based on the human body location, indoor humidity, return air temperature, air outlet temperature of the air conditioner, and air outlet wind speed, and the air supply mode of the air conditioner is controlled according to the second perceived temperature. Therefore, this control device can control the air supply mode of the air conditioner based on the human body location and physical characteristics, improving user comfort without requiring user operation, making it more intelligent, and allowing for more precise adjustment of fan speed and air supply temperature. Furthermore, during the operation of the air conditioner, the user location, air outlet temperature, return air temperature, and indoor humidity are continuously acquired. This ensures that even if the human body location changes, the air supply mode of the air conditioner is adjusted in real time accordingly, effectively improving user comfort.

[0086] The air conditioner of this invention, through the aforementioned control device or controller, can control the airflow mode based on the user's position and physical characteristics, improving user comfort without requiring user intervention, making it more intelligent, and allowing for more precise adjustment of fan speed and airflow temperature. Furthermore, during operation, the air conditioner continuously acquires user position, air outlet temperature, return air temperature, and indoor humidity. This ensures that even if the user's position changes, the airflow mode adjusts in real time accordingly, effectively enhancing user comfort.
