Description

Technical Field

[0001] This invention belongs to the field of environmental temperature and humidity regulation technology, specifically relating to an environmental temperature and humidity regulation method, device and storage medium based on physical comfort. Background Technology

[0002] In the air conditioning field, user thermal comfort is often used as a key indicator to evaluate the performance of air conditioning systems. However, current research on indoor thermal comfort is mostly limited to the air conditioning equipment itself, i.e., how to improve the performance of air conditioning, without fully considering human physiological and psychological factors. The Predicted Mean Vote (PMV) index indicates that research on human thermal comfort involves disciplines such as building thermophysics, the physiology of human thermoregulation mechanisms, and human psychology. It is determined by factors such as skin surface air temperature, airflow velocity, relative humidity, mean radiant temperature, thermal resistance of clothing, and activity intensity. Therefore, existing air conditioning systems cannot quantify human thermal comfort during operation, and the control of indoor temperature and humidity cannot be based on human thermal comfort. Furthermore, they cannot automatically adjust based on the temperature and humidity of the human body surface, thus failing to achieve optimal human thermal comfort. Therefore, providing a method for automatically adjusting environmental temperature and humidity based on human comfort has become an urgent problem to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a method, device, and storage medium for regulating environmental temperature and humidity based on human comfort, in order to solve the problems existing in the prior art that the thermal comfort of the human body cannot be quantified during operation, and the control of indoor environmental temperature and humidity cannot be based on the thermal comfort of the human body, nor can it be automatically adjusted based on the temperature and humidity of the human body surface.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Firstly, a method for regulating environmental temperature and humidity based on physical comfort is provided, including:

[0006] The ambient temperature of a designated area is obtained, and the humidity of the designated area affecting the perceived body temperature of the target human body is determined based on the ambient temperature, wherein the designated area is the area where the target human body is located;

[0007] Using the perceived humidity and the ambient temperature, the perceived humidity index of the target human body is determined. The perceived humidity index is used to characterize the degree of influence of the ambient temperature and the perceived humidity on the comfort of the target human body. The larger the perceived humidity index, the greater the influence of the ambient temperature and the perceived humidity on the comfort of the target human body.

[0008] Determine whether the perceived body index is greater than the index threshold;

[0009] If so, then acquire the infrared thermal imaging image of the target human body;

[0010] Based on the infrared thermal imaging image, the initial body temperature of the target human body is determined, and the initial body temperature is corrected for errors to obtain the actual body temperature of the target human body.

[0011] The surface humidity of the target human body is determined based on the actual body temperature and the ambient temperature.

[0012] Based on the actual body temperature, the body surface humidity, and the ambient temperature, a temperature and humidity adjustment command is generated.

[0013] The temperature and humidity adjustment command is sent to the temperature and humidity device so that the temperature and humidity device adjusts the ambient temperature and humidity of the specified area based on the temperature and humidity adjustment command.

[0014] Based on the above-disclosed content, this invention, during operation, calculates the perceived humidity of a designated area by collecting the ambient temperature of that area. Then, based on the ambient temperature and perceived humidity of the designated area, it determines the perceived humidity index of the target human body. This index characterizes the degree of influence of the ambient temperature and perceived humidity of the designated area on human comfort; a higher index indicates greater discomfort. This step effectively quantifies the thermal comfort of the human body within the designated area. Subsequently, temperature and humidity can be adjusted based on the human body's thermal comfort.

[0015] Specifically, this invention first uses the body temperature index to determine whether the human body is in a state of thermal discomfort. When the human body is determined to be in a state of thermal discomfort, the ambient temperature and humidity are adjusted. This involves acquiring a thermal infrared image of the human body, determining the initial body temperature based on the image, and simultaneously correcting for errors to obtain the actual body temperature. Next, based on the actual body temperature and the ambient temperature, the body surface humidity is determined. Finally, based on the actual body temperature, body surface humidity, and ambient temperature, a temperature and humidity adjustment command is generated and sent to the temperature and humidity device to ultimately achieve automatic adjustment of the ambient temperature and humidity.

[0016] Through the above design, this invention can quantify human thermal comfort during the operation of temperature and humidity equipment, and use this as a basis for determining whether environmental temperature and humidity can be adjusted. Simultaneously, when it is determined that the human body is in a state of thermal discomfort, the actual body temperature is obtained by real-time acquisition of thermal infrared imaging images of the human body, and the surface humidity of the human body is determined based on the actual body temperature and ambient temperature. Then, the ambient temperature and humidity can be adjusted according to the ambient temperature, the actual body temperature, and the surface humidity. Therefore, this invention can automatically adjust indoor temperature and humidity based on human thermal comfort, and ultimately determine the adjustment command based on the human body's temperature and humidity. This enables precise control of temperature and humidity equipment, improves indoor environmental comfort, and optimizes human thermal comfort.

[0083] Example:

[0084] See Figure 1 As shown, the environmental temperature and humidity regulation method based on human comfort provided in this embodiment can automatically adjust the indoor temperature and humidity according to the human body's thermal comfort, and can ultimately determine the adjustment command based on the human body's temperature and humidity. In this way, precise control of temperature and humidity equipment can be achieved, which can improve the comfort of the indoor environment and thus optimize the human body's thermal comfort. Therefore, this method is suitable for large-scale application and promotion in the field of environmental temperature and humidity regulation. In this embodiment, the method can be, but is not limited to, operated on the temperature and humidity regulation terminal side. The temperature and humidity regulation terminal can be, but is not limited to, a personal computer (PC), tablet computer, or smartphone. It is understood that the aforementioned execution subject does not constitute a limitation on the embodiment of this application. Accordingly, the operation steps of this method can be, but are not limited to, the steps S1 to S8 below.

[0085] S1. Obtain the ambient temperature of a designated area, and determine the humidity of the designated area that affects the perceived body temperature of the target human body based on the ambient temperature. The designated area is the area where the target human body is located. In this embodiment, the designated area is an indoor area. The ambient temperature may include, but is not limited to, a first temperature when the designated area is under a first temperature measurement condition and a second temperature when the designated area is under a second temperature measurement condition. The first temperature is used to characterize the room temperature of the designated area. The first temperature measurement condition may be a dry-bulb temperature measurement condition (i.e., a dry-bulb thermometer exposed to the air but not directly exposed to the sun). The second temperature measurement condition may be, but is not limited to, a wet-bulb temperature measurement condition. Specifically, a wet-bulb thermometer exposed to the air but not directly exposed to the sun is used for measurement.

[0086] After obtaining the ambient temperature of the designated area, it is necessary to determine the humidity of the designated area that affects the target human body based on the ambient temperature, so as to quantify the thermal comfort of the target human body based on the humidity of the affected area and the ambient temperature. For example, the humidity of the affected area can be calculated by, but is not limited to, the following steps S11 and S12.

[0087] S11. Based on the first temperature, calculate the first water vapor pressure of the designated area, and use the first temperature and the second temperature to calculate the second water vapor pressure of the designated area; in this embodiment, the first water vapor pressure may be, but is not limited to, the water vapor pressure when the gas phase and liquid phase of water vapor in the aforementioned designated area reach equilibrium, while the second water vapor pressure is the actual water vapor pressure in the designated area; in specific implementation, the first water vapor pressure may be calculated using, but is not limited to, the first temperature, according to the following formula (1).

[0088]

[0089] In the above formula (1), A1 represents the first water vapor pressure, t1 represents the first temperature, and α1, α2, and α3 are all water vapor pressure coefficients; optional, for example, α1 = 23.1964, α2 = 3816.44, and α3 = -46.13.

[0090] Therefore, the natural logarithm of the first water vapor pressure can be determined by the aforementioned formula (1). Finally, the first water vapor pressure of the specified area can be calculated by using the antilogarithm.

[0091] Meanwhile, the calculation process for the second water vapor pressure can be, but is not limited to, the steps S11a to S11c below.

[0092] S11a. Obtain the atmospheric pressure of the designated area; In this embodiment, an atmospheric pressure sensor may be used, but is not limited to, to measure the atmospheric pressure of the designated area. Then, the atmospheric pressure sensor sends the atmospheric pressure to the temperature and humidity control device, so that the temperature and humidity control device, in conjunction with the aforementioned first temperature and second temperature, can calculate the humidity parameter of the designated area; wherein, the calculation process of the humidity parameter is as shown in step S11b below.

[0093] S11b. Using the first temperature, the second temperature, and the atmospheric pressure, calculate the humidity parameter according to the following formula (2).

[0094]

[0095] In equation (2) above, s represents the humidity parameter. Both represent the regional humidity coefficient, A tmt1 represents the atmospheric pressure, and t2 represents the second temperature; in specific applications, for example, β1 = 166.31, ε = 647.3, φ1 = 1.01. β2 = 267.38, φ2 = 1.88.

[0096] Thus, after calculating the humidity parameter based on the aforementioned formula (2), the second water vapor pressure of the specified area can be calculated using this formula. The calculation process is shown in step S11c below.

[0097] S11c. Based on the humidity parameter and the atmospheric pressure, the second water vapor pressure is calculated according to the following formula (3).

[0098]

[0099] In the above formula (3), A2 represents the second water vapor pressure.

[0100] Therefore, based on the aforementioned formulas (1), (2) and (3), after calculating the first water vapor pressure and the second water vapor pressure in the specified area, the ratio of the two can be used as the perceived humidity, as shown in step S12 below.

[0101] S12. The ratio between the first water vapor pressure and the second water vapor pressure is taken as the perceived humidity of the designated area on the target human body; in specific applications, the percentage of the ratio between the first water vapor pressure and the second water vapor pressure is taken as the perceived humidity of the designated area on the target human body.

[0102] After calculating the perceived humidity of the designated area on the target human body through the aforementioned steps S11 and S12, the perceived humidity and ambient temperature can be used to quantify the thermal comfort of the target human body in the designated area. The quantification process can be, but is not limited to, the steps shown in step S2 below.

[0103] S2. Using the perceived humidity and the ambient temperature, determine the perceived comfort index of the target human body. The perceived comfort index is used to characterize the degree of influence of the ambient temperature and the perceived humidity on the comfort of the target human body. The larger the perceived comfort index, the greater the influence of the ambient temperature and the perceived humidity on the comfort of the target human body. In practical applications, the larger the perceived comfort index, the worse the comfort of the target human body. Therefore, the perceived comfort index can be used to measure the thermal comfort of the target human body in a specified area.

[0104] Furthermore, for example, the body sensation index of the target human body can be calculated based on the perceived humidity and the first temperature, according to the following formula (4).

[0105] D=t1-(0.55-0.55E)(t1-58) (4)

[0106] In the above formula (4), D represents the body comfort index of the target human body, t1 represents the first temperature, and E represents the humidity of the body comfort influence. Thus, through the above formula (4), the thermal comfort of the target human body in the specified area can be quantified into the body comfort index. Then, based on the body comfort index, it can be determined whether the target human body is in a state of thermal discomfort, as shown in step S3 below.

[0107] S3. Determine whether the body sensation index is greater than the index threshold. In this embodiment, when the body sensation index is between 60 and 65, it is determined that the target human body feels comfortable in the specified area (i.e., good thermal comfort). When the body sensation index is greater than 80, it can be indicated that the target human body feels uncomfortable in the specified area. Therefore, in this embodiment, the index threshold is set to 80. Thus, when the body sensation index is greater than 80, the target human body can be determined to be in a state of thermal discomfort.

[0108] After determining that the target human body is in a state of thermal discomfort, the actual body temperature and surface humidity of the target human body can be measured so as to adjust the ambient temperature and humidity in the designated area based on the actual body temperature and surface humidity of the target human body; wherein, the measurement process of the actual body temperature of the target human body can be, but is not limited to, as shown in steps S4 and S5 below.

[0109] S4. If so, acquire the infrared thermal imaging image of the target human body; in this embodiment, for example, the temperature and humidity control terminal may be electrically connected to an infrared thermal imaging temperature measuring device, so when it is determined that the target human body is in a state of thermal discomfort, the temperature and humidity control device can send an image acquisition command to the infrared thermal imaging temperature measuring device, and then the infrared thermal imaging temperature measuring device can acquire the infrared thermal imaging image of the target human body based on the command and upload it to the temperature and humidity control device.

[0110] After obtaining the infrared thermal imaging image of the target human body, the actual body temperature of the target human body can be determined based on the image, as shown in step S5 below.

[0111] S5. Based on the infrared thermal imaging image, determine the initial body temperature of the target human body, and perform error correction on the initial body temperature to obtain the actual body temperature of the target human body. In this embodiment, the infrared thermal imaging image can directly display the measured body temperature of the target human body; therefore, the measured body temperature is used as the initial body temperature of the target human body. However, since there is a temperature error when measuring temperature using infrared thermal imaging images, this error is related to the distance between the target human body and the infrared thermal imaging temperature measuring device. When this distance varies within 1 to 3 meters, the measurement result will deviate from the actual body temperature by a maximum of 3°C. Therefore, in order to achieve accurate measurement of the target human body temperature, this embodiment also needs to perform error correction on the initial body temperature obtained based on the infrared thermal imaging image to ensure the accuracy of subsequent temperature and humidity adjustment based on the actual body temperature.

[0112] In practical applications, the initial body temperature can be corrected for errors using steps S51 to S56, but is not limited to these steps.

[0113] S51. Perform key point detection on the infrared thermal imaging image to obtain the image coordinates of multiple facial key points of the target human body. In this embodiment, for example, but not limited to, a trained deep neural network can be used to perform key point detection on the infrared thermal imaging image; for example, a trained CNN neural network can be used. Among them, facial key points can include, but are not limited to, eye sockets, cheeks, upper and lower lips, eyebrows, etc. Thus, a trained deep neural network can be used to detect the coordinates of multiple facial key points of the target human body in the infrared thermal imaging image.

[0114] After obtaining the image coordinates of the key facial features of the target human body, it is also necessary to obtain the world coordinates of the key facial features of the target human body so as to calculate the distance between the target human body and the infrared thermal imaging temperature measurement device based on the coordinates of the key facial features in the two coordinate systems; the calculation process is shown in steps S52 and S53 below.

[0115] S52. Obtain the world coordinates of each facial key point among multiple facial key points, and calculate the translation matrix between the world coordinate system and the corresponding image coordinate system of the infrared thermal imaging image based on the world coordinates and image coordinates of each facial key point. In specific implementation, the world coordinates of any facial key point can be obtained, but are not limited to, according to the national standard (adult head and face dimensions, GB / T2428-1998). Then, the translation matrix (i.e., the translation amount) between the two coordinate systems can be calculated based on the world coordinates and image coordinates of each facial key point, so as to obtain the distance between the target human body and the infrared thermal imaging temperature measurement device based on the translation matrix.

[0116] In this embodiment, based on the world coordinates and image coordinates of any facial key point, an equation for solving the translation matrix can be constructed, as shown below:

[0117]

[0118] In equation (6) above, u n ,v n This represents the x-coordinate and y-coordinate of the image representing the nth facial landmark. This represents the camera intrinsic parameter matrix of the infrared thermal imaging temperature measurement device (which is a known matrix), x n ,y n Let x and y represent the world x and y coordinates of the nth facial landmark, and N represent the total number of facial landmarks. R represents the rotation matrix. This represents the translation matrix.

[0119] Therefore, by using the aforementioned formula (6) and the image coordinates and world coordinates of multiple facial key points, multiple sets of translation matrix equations can be constructed. Then, by solving the multiple sets of equations simultaneously, the translation matrix between the world coordinate system and the image coordinate system can be obtained. After obtaining the translation matrix, the distance between the target human body and the infrared thermal imaging temperature measurement device can be obtained, as shown in step S53 below.

[0120] S53. Based on the translation matrix, determine the distance between the target human body and the target device, wherein the target device is the infrared thermal imaging image acquisition device; in this embodiment, the infrared thermal imaging image acquisition device is an infrared thermal imaging temperature measurement device.

[0121] After obtaining the distance between the target human body and the target device, temperature error correction can be performed based on this distance, as shown in steps S54 to S56 below.

[0122] S54. Obtain the temperature compensation database, wherein the temperature compensation database stores temperature compensation values ​​corresponding to different temperature measurement distances; in this embodiment, the temperature compensation database can be preset in the temperature and humidity control terminal; thus, after knowing the distance between the target human body and the target device, the temperature compensation value corresponding to the distance can be matched from the temperature compensation database to perform temperature error correction, as shown in steps S55 and S56 below.

[0123] S55. Based on the distance between the target human body and the target device, determine the temperature compensation value of the target human body from the temperature compensation database.

[0124] S56. The actual body temperature of the target human body is calculated using the temperature compensation value of the target human body and the initial body temperature. In this embodiment, the temperature compensation value is either positive or negative. Therefore, after obtaining the temperature compensation value of the target human body, the temperature compensation value is added to the initial body temperature to obtain the actual body temperature of the target human body.

[0125] Thus, through the aforementioned steps S51 to S56, the body temperature correction of the target human body can be completed, thereby accurately obtaining the actual body temperature of the target human body; then, based on the actual body temperature, the surface humidity of the target human body can be calculated, as shown in step S6 below.

[0126] S6. Determine the surface humidity of the target human body based on the actual body temperature and the ambient temperature; in this embodiment, the calculation process of surface humidity may be, but is not limited to, the steps S61 and S62 below.

[0127] S61. Calculate the second water vapor pressure in the designated area using the first temperature and the second temperature; in this embodiment, the calculation process of the second water vapor pressure can be referred to the aforementioned steps S11a to S11c, and will not be repeated here.

[0128] After calculating the second water vapor pressure in the designated area, the surface humidity of the target human body can be calculated by combining the actual body temperature of the target human body with the room temperature of the designated area, as shown in step S62 below.

[0129] S62. The surface humidity of the target human body is calculated based on the actual body temperature, the first temperature and the second water vapor pressure, and according to the following formula (5).

[0130]

[0131] In equation (5) above, s r The surface humidity of the target human body is represented by ρ, which represents the human body humidity coefficient, and t is the humidity of the target human body. r The actual body temperature is represented by t1, the first temperature is represented by t1, and the second water vapor pressure is represented by A2. In specific applications, ρ can be, but is not limited to, 0.7947.

[0132] After calculating the surface humidity of the target human body based on the aforementioned formula (5), the actual body temperature and the room temperature of the designated area can be combined to adjust the temperature and humidity, as shown in steps S7 and S8 below.

[0133] S7. Based on the actual body temperature, the body surface humidity, and the ambient temperature, generate a temperature and humidity adjustment command; in this embodiment, the specific generation process of the temperature and humidity adjustment command may be, but is not limited to, the steps S71 to S79 ​​below.

[0134] S71. Based on the actual body temperature, determine the sweating state of the target human body, wherein the sweating state includes a first sweating state and a second sweating state; in this embodiment, if the actual body temperature is greater than 34°C, the target human body is determined to be in the first sweating state, and if it is less than 34°C, it is in the second sweating state. The first sweating state is a visible sweating state (i.e., sweat glands secrete sweat), while the second sweating state is a latent sweating state (i.e., water diffuses to the skin surface through the stratum corneum and then sweats through evaporation); thus, different temperature and humidity adjustments can be made according to the sweating state of the target human body, as shown in steps S72 to S79 ​​below.

[0135] S72. If the target human body is in the first sweating state, then determine whether the first temperature is less than or equal to the first preset temperature; in this embodiment, the first preset temperature may be, but is not limited to, 26 degrees Celsius.

[0136] S73. If yes, then a first temperature and humidity adjustment command is generated, wherein the first temperature and humidity adjustment command is used to maintain a first temperature and maintain the current ambient humidity in the designated area; otherwise, a second temperature and humidity adjustment command is generated, wherein the second temperature and humidity adjustment command includes a first controlled temperature and a first controlled humidity in the designated area, and the first controlled temperature is lower than the first preset temperature, and the first controlled humidity is equal to the current ambient humidity; in specific applications, when the target human body is sweating through sweat glands, it indicates that the body temperature is high due to high activity intensity. At the same time, since the room temperature in the designated area is less than or equal to 26 degrees Celsius, it indicates that the indoor temperature is a comfortable temperature. In this case, there is no need to adjust the temperature and humidity of the designated area; it is only necessary to maintain the current temperature and current ambient humidity. Similarly, if the first temperature is greater than 26 degrees Celsius, it indicates that the indoor temperature is too high. In this case, it is necessary to lower the temperature of the designated area and maintain the humidity of the designated area. Thus, the generated second temperature and humidity adjustment command includes the first controlled temperature and the first controlled humidity. In addition, in this embodiment, setting the first controlled temperature to be lower than the first preset temperature can achieve a rapid cooling effect.

[0137] Optionally, if the target human body is in the second perspiration state, the temperature and humidity can be adjusted using the following steps S74 to S76.

[0138] S74. If the target human body is in the second sweating state, determine whether the surface humidity is less than or equal to the first preset humidity. In specific applications, for example, the first preset humidity may be, but is not limited to, 25%. Therefore, when the surface humidity is less than or equal to 25%, it indicates that the target human body is in a dry skin state. At this time, it is necessary to combine the temperature for further judgment in order to determine the temperature and humidity adjustment instructions, as shown in steps S75 and S76 below.

[0139] S75. If yes, then determine whether the first temperature is less than or equal to the first preset temperature.

[0140] S76. If yes, then a third temperature and humidity adjustment command is generated, wherein the third temperature and humidity adjustment command includes a second controlled humidity of the specified area, and the second controlled humidity is greater than the first preset humidity; otherwise, a fourth temperature and humidity adjustment command is generated, wherein the fourth temperature and humidity adjustment command includes a second controlled temperature and a third controlled humidity, wherein the second controlled temperature is lower than the first preset temperature, and the third controlled humidity is higher than the first preset humidity. In specific applications, if the target human body is in a state of dry skin, and the room temperature of the specified area is less than or equal to 26 degrees Celsius, then it indicates that the skin is dry and it is not caused by excessively high indoor temperature. In this case, it is only necessary to adjust the humidity in the specified area, that is, generate a second controlled humidity, and at the same time, set the second controlled humidity to be greater than the first preset humidity, thereby quickly increasing the environmental humidity of the specified area.

[0141] Similarly, if the room temperature in the designated area is greater than 26 degrees Celsius, it indicates that the dry skin is caused by the excessively high indoor temperature in the designated area. In this case, the temperature and humidity of the designated area can be adjusted simultaneously, that is, a second temperature control and a third humidity control can be generated. In this way, the indoor temperature can be reduced while the indoor humidity is increased, thereby quickly improving the thermal comfort of the target human body.

[0142] Furthermore, if the surface humidity is greater than the first preset humidity, the method further includes:

[0143] S77. Determine whether the surface humidity is greater than the second preset humidity; In this embodiment, the second preset humidity may be, but is not limited to, 45%. That is, when the surface humidity is greater than 45%, it means that the skin of the target human body is relatively moist. At this time, it is necessary to adjust the temperature and humidity according to the room temperature of the specified area, as shown in steps S78 and S79 below.

[0144] S78. If yes, then determine whether the first temperature is less than the second preset temperature, wherein the second preset temperature is less than the first preset temperature; in this embodiment, the second preset temperature may be, but is not limited to, 20 degrees Celsius.

[0145] S79. If yes, then a fifth temperature and humidity adjustment command is generated, wherein the fifth temperature and humidity adjustment command includes a third control temperature, and the third control temperature is the first preset temperature; otherwise, a sixth temperature and humidity adjustment command is generated, wherein the sixth temperature and humidity adjustment command is a dehumidification command. In specific applications, if the room temperature of the specified area is less than 20 degrees Celsius, then it indicates that the human skin is damp and the room temperature of the specified area is too low. At this time, it is necessary to raise the temperature, that is, generate the third control temperature, so as to raise the temperature to a comfortable human body temperature. At the same time, if the room temperature of the specified area is greater than 20 degrees Celsius, then it indicates that the human skin is damp due to indoor humidity. In this case, it is necessary to perform a dehumidification operation on the specified area, that is, generate a dehumidification command.

[0146] In addition, if the target human body is in the second perspiration state and the body surface humidity is between the first preset humidity and the second preset humidity, then there is no need to adjust the temperature and humidity of the designated area.

[0147] Thus, through the aforementioned steps S71 to S79, a temperature and humidity adjustment command that maximizes the thermal comfort of the target human body can be generated based on the target human body's different perspiration states, combined with the room temperature of the designated area and the surface humidity of the target human body. Then, the command is sent to the temperature and humidity device to complete the temperature and humidity adjustment of the designated area, as shown in step S8 below.

[0148] S8. The temperature and humidity adjustment command is sent to the temperature and humidity device so that the temperature and humidity device adjusts the ambient temperature and humidity of the designated area based on the temperature and humidity adjustment command; in this embodiment, the temperature and humidity device may be, but is not limited to, an air conditioner, a heater, or a humidifier, and may be any device capable of temperature and humidity adjustment.

[0149] Therefore, the environmental temperature and humidity regulation method based on human comfort, as described in the aforementioned steps S1 to S8, can automatically adjust the indoor temperature and humidity according to the human body's thermal comfort, and can ultimately determine the adjustment command based on the human body's temperature and humidity. In this way, precise control of temperature and humidity equipment can be achieved, which can improve the comfort of the indoor environment and thus optimize the human body's thermal comfort.
