[0030] This embodiment provides a method for controlling an air conditioner in a sports venue that operates on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0031] Figure 2 This is a flowchart illustrating a method for controlling air conditioning in a sports venue according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:
[0032] Step S201: Control the air conditioner to start operating according to the initial control parameters, wherein the initial control parameters are one or more of the initial set wind speed, initial set temperature and initial set humidity of the air conditioner in the sports venue.
[0033] Specifically, the initial control parameters of the air conditioning are first set according to the nature of the sports venue and the expected type of sports. These parameters include, but are not limited to, wind speed, temperature, and humidity, which are calculated based on a simplified PMV model to meet the initial thermal comfort needs of athletes in this sports environment. The initial settings of wind speed, temperature, and humidity are calculated based on the simplified PMV model in the briefing document, that is, a preliminary environmental parameter is preset before athletes enter the sports area to provide a preliminary comfortable environment.
[0034] Step S202: Obtain the user's metabolic rate at the above-mentioned sports venue, and determine the user's exercise intensity level based on the user's metabolic rate, wherein the user's metabolic rate and the exercise intensity level are positively correlated.
[0035] Specifically, by monitoring physiological data such as heart rate and skin temperature, multiple linear regression analysis is used to calculate the user's real-time metabolic rate, thereby determining the exercise intensity level. There is a positive correlation between exercise intensity level and metabolic rate; that is, the higher the metabolic rate, the higher the exercise intensity level, and the corresponding changes in the demand for ambient temperature, humidity, and wind speed. In this way, the current exercise state of the participant can be accurately identified, providing a basis for subsequent parameter adjustments.
[0036] Step S203: Adjust the initial control parameters according to the above-mentioned exercise intensity level to obtain the adjusted control parameters;
[0037] Specifically, based on a defined exercise intensity level, the SPTCM model is used to assess the gap between the current environmental parameters and the optimal thermal comfort level. If the current parameters are found to be below optimal, wind speed, temperature, or humidity will be adjusted in a predetermined order until the SPTCM value approaches zero, indicating that the environment has reached the optimal thermal comfort level for the exerciser. The human body's sensitivity to wind speed, humidity, and temperature varies at different exercise intensities; low-intensity exercise prioritizes wind speed adjustment, medium-intensity exercise prioritizes humidity adjustment, and high-intensity exercise prioritizes temperature adjustment. This tiered adjustment strategy ensures that optimal thermal comfort can be quickly reached and maintained even with changes in exercise intensity.
[0038] Step S204: Control the air conditioner to operate according to the adjusted control parameters.
[0039] Specifically, after parameter adjustments, the air conditioner is immediately controlled to execute the new control parameters to ensure that the indoor environment quickly reaches and remains at the optimal thermal comfort level. This real-time adjustment and execution mechanism, combining the air conditioner's control logic and heat exchange efficiency model, ensures that the indoor environment maintains dynamic equilibrium after changes, meeting the needs of active individuals. When executing new control parameters, the amount of heat exchange between indoors and outdoors is monitored, and the air conditioner's cooling power is adjusted as needed to maintain a dynamic balance between indoor and outdoor temperatures, ensuring that the indoor environment remains within the optimal thermal comfort range under all circumstances.
[0040] This embodiment demonstrates that, based on the different exercise intensity levels of athletes, the influence of environmental wind speed, humidity, and temperature varies depending on the exercise intensity level. This solution allows for personalized adjustments to the air conditioning based on the exercise intensity level of athletes in the sports venue, thereby improving the comfort of athletes and ultimately enhancing the user experience.
[0041] Specifically, traditional air conditioning systems typically use a uniform temperature setting, which fails to meet the varying temperature needs of different areas due to factors such as the intensity of human activity and environmental conditions. This singular control method not only wastes energy but also leads to uncomfortable temperatures in some areas, affecting the user experience. While current temperature control systems can achieve intelligent control to some extent, they still have some shortcomings. For example, most systems rely solely on data from temperature sensors for control, ignoring the impact of human activity intensity on temperature, humidity, and airflow requirements. Furthermore, maintaining a dynamic balance between indoor and outdoor temperatures after air conditioning adjustments remains a difficult problem, making it impossible to achieve the optimal comfort environment for indoor occupants simply by adjusting the air conditioning.
[0042] The above-mentioned solution proposes an intelligent air conditioning control method for optimal comfort environment. By monitoring the intensity of human exercise, analyzing the indoor environmental sensitivity parameters experienced by the exerciser under that intensity, calculating the human body's urgent need to change a certain environmental parameter under that exercise state, the air conditioner adjusts the cooling (heating) power, and then adjusts the temperature, humidity, or fan speed to ensure that the dynamic balance of indoor and outdoor temperatures is not affected after changes in indoor environmental parameters, so as to maintain the indoor environment at the optimal comfort level for the human body and maximize the comfort of people in large indoor sports venues.
[0043] In the specific implementation process, controlling the air conditioner to start operating according to the initial control parameters can be achieved through the following steps: obtaining the skin temperature of all users; calculating the average skin temperature of all users to obtain the average skin temperature value; obtaining the ambient temperature value of the sports venue and the thermal resistance value of the clothing of the users; determining the initial set temperature based at least on the average skin temperature value, the ambient temperature value, and the thermal resistance value of the clothing, and controlling the air conditioner to start operating at least according to the initial set temperature, wherein the average skin temperature value and the initial set temperature are negatively correlated, the ambient temperature value and the initial set temperature are negatively correlated, and the thermal resistance value of the clothing is positively correlated with the initial set temperature.
[0044] In this scheme, the skin temperature information of all athletes provides direct feedback on their perceived ambient temperature, which helps to build a more accurate thermal comfort model. This guides the optimization and adjustment of parameters. The use of average skin temperature values enhances the objectivity and accuracy of thermal comfort assessment, allowing for dynamic adjustment of the initial set temperature based on the actual conditions within the sports venue to achieve higher comfort standards. By comprehensively considering ambient temperature and clothing thermal resistance, the initial set temperature can be adjusted according to actual conditions, ensuring optimal thermal comfort for athletes even under variable environmental conditions. Based on the parameter relationships in the simplified PMV model, a negative correlation between average skin temperature and initial set temperature, a negative correlation between ambient temperature and initial set temperature, and a positive correlation between clothing thermal resistance and initial set temperature can be derived. Through calculations using this model, the initial set temperature can be adjusted more precisely, ensuring that the indoor environment meets human thermal comfort requirements while avoiding energy waste, achieving efficient and personalized thermal comfort control.
[0045] Specifically, to accurately reflect the thermal comfort needs of all athletes, skin temperature information of all athletes is acquired through smart wearable devices or other sensors. By monitoring and collecting athletes' skin temperature, we can gain a more intuitive understanding of their perception of the current indoor ambient temperature, which is one of the important physiological parameters for assessing and adjusting the thermal comfort of the indoor environment. By observing the negative correlation between average skin temperature and the initial set temperature, as well as the influence of ambient temperature and clothing thermal resistance on the initial set temperature, we can comprehensively consider various factors and formulate an initial set temperature suitable for all athletes, avoiding the bias that may be introduced by individual data.
[0046] Statistical analysis of skin temperature data from all athletes yields an average skin temperature value, reflecting the overall thermal comfort of the group. Calculating this average is a crucial step in determining the initial set temperature, avoiding errors that might arise from adjusting the environment based solely on individual user data, and ensuring that the adjusted temperature better meets the needs of the majority.
[0047] In addition to measuring skin temperature, it is also necessary to monitor the ambient temperature in the sports venue in real time and collect information on the thermal resistance of the clothing worn by athletes. The thermal resistance of clothing reflects the degree to which clothing impedes heat transfer, while ambient temperature directly affects the heat exchange between the human body and the surrounding environment.
[0048] Specifically, such as Figure 3 As shown, when someone enters a sports field in a large indoor sports venue, to provide the best sports environment temperature and keep the indoor temperature within the optimal comfort range for the athletes, the concept of thermal comfort is introduced to describe the degree of human satisfaction with the indoor environment temperature. The predicted mean value (PMV) index, used to evaluate indoor thermal comfort, is used to quantify the athletes' thermal comfort level. PMV represents the temperature sensations of the vast majority of people in the same environment; it is influenced by many factors, and its calculation process is very complex, resulting in a slow solution speed.
[0049] Therefore, to provide athletes with a good initial exercise environment, a simplified PMV model is first used to calculate the ambient temperature required for a particular exercise, i.e., the initial set temperature of the air conditioner, and the air conditioner is then controlled to cool / heat at this temperature. For ease of calculation, the simplified PMV model ignores the influence of factors such as air velocity and humidity; the calculation formula is shown below:
[0050]
[0051] In the formula, λ represents the PMV index value; t sk This represents the average skin temperature of the human body under near-comfort conditions, approximated as 33.5℃; t in M represents the ambient temperature in which the human body is located; M represents the heat generated by human metabolism; I represents the ambient temperature in which the human body is located. cl The thermal resistance of clothing is expressed as 0.05 (m) in summer. 2 ·℃) / W, which can be taken as 0.11(m) in winter. 2 ·℃) / W.
[0052] Based on the above formula, the ambient temperature t when λ is 0 can be calculated. in You can give the air conditioner an initial temperature value.
[0053] In some embodiments, obtaining the metabolic rate of users in the aforementioned sports venue can be achieved through one of the following steps: When the number of users in the sports venue is 1, obtain the user's heart rate and determine the user's metabolic rate based on the heart rate, wherein the heart rate and the user's metabolic rate are positively correlated; When the number of users in the sports venue is greater than 1 and all users are of the same gender, obtain the heart rate of each user, determine the metabolic rate of each user based on the heart rate, and calculate the average of the metabolic rates of all users to obtain the user's metabolic rate; When the number of users in the sports venue is greater than 1 and all users have two genders, obtain the heart rate of each user, determine the metabolic rate of each user based on the gender and the heart rate, and calculate the average of the metabolic rates of all users to obtain the user's metabolic rate, wherein the metabolic rates of men and women are different.
[0054] This solution leverages the positive correlation between heart rate monitoring and metabolic rate calculation to directly adjust the metabolic rate of exercisers in real time based on heart rate changes. This allows for customized environmental adjustments at different exercise intensities, enhancing thermal comfort. When the group is of the same gender, the average metabolic rate calculation reflects overall thermal comfort needs. By converting heart rate to metabolic rate, air conditioning parameters can be adjusted based on the average metabolic rate, ensuring all users experience suitable thermal comfort. Considering the difference in metabolic rates between men and women at the same heart rate, calculating separately and then averaging allows for a more detailed assessment of the group's thermal comfort needs, ensuring that indoor environmental parameter adjustments consider the comfort of all individuals.
[0055] When there are multiple users of the same gender in a sports venue, the average metabolic rate of the group is determined by monitoring the heart rate of each user individually, calculating their individual metabolic rate, and then averaging the results. This approach considers the average state of the group and can more comprehensively reflect the overall heat load demand.
[0056] When both male and female users are present in a sports venue, the individual metabolic rate is calculated by monitoring each user's heart rate separately and combining this with gender information. The average metabolic rate is then calculated to reflect the average thermal comfort needs of the mixed-sex group. Because the conversion formulas for metabolic rates differ between men and women, this method can more accurately reflect the thermal load of the mixed-sex group.
[0057] Specifically, traditional PMV (Potentially Measured Value) has a certain bias in predicting thermal sensation, which is particularly pronounced when predicting the thermal sensation of athletes. This bias increases with increasing metabolic rate and skin temperature, becoming more significant as the deviation from thermoneutrality increases. As exercise intensity increases, the athlete's metabolic rate increases, and their heart rate also increases. There is a positive correlation between metabolic rate and heart rate. The conversion relationship between human heart rate and metabolic rate is shown in the following formula:
[0058]
[0059] In the formula, M m M fm These represent the metabolic rates for men and women, respectively, in units of metrology (met) and nitrogen (N). hr This represents the human heart rate, measured in bpm.
[0060] In the specific implementation process, determining the user's exercise intensity level based on the aforementioned user metabolic rate can be achieved through the following steps: when the user's metabolic rate is less than a first threshold, the user's exercise intensity level is determined to be a first level; when the user's metabolic rate is greater than or equal to the first threshold and less than a second threshold, the user's exercise intensity level is determined to be a second level, wherein the first threshold is less than the second threshold, and the exercise intensity of the first level is lower than that of the second level; when the user's metabolic rate is greater than or equal to the second threshold, the user's exercise intensity level is determined to be a third level, wherein the exercise intensity of the second level is lower than that of the third level.
[0061] This solution accurately distinguishes low-intensity exercise by setting a first threshold, providing users with appropriate adjustment plans and enhancing comfort. Setting a second threshold promptly identifies medium-intensity exercise, offering users suitable adjustment plans and further strengthening personalized comfort management. By setting a second threshold and identifying high-intensity exercise, it provides users with appropriate adjustment plans, offering an optimal thermal comfort environment, especially during strenuous exercise, effectively preventing heat stress and fatigue accumulation.
[0062] When a user's metabolic rate is below a first threshold, their exercise intensity level is determined to be Level 1, i.e., low-intensity exercise. For example, the metabolic rate range for low-intensity exercise is <4.7 Met. This criterion helps the system quickly identify the exerciser's current exercise status, providing precise guidance for subsequent adjustments to environmental parameters.
[0063] During low-intensity exercise, the human body is more sensitive to ambient wind speed. Prioritizing wind speed adjustment can effectively improve thermal comfort, reduce excessive regulation of temperature and humidity, and save energy. When the metabolic rate falls below a first threshold, the system immediately identifies and reacts by prioritizing ambient wind speed adjustment to ensure that exercisers experience optimal thermal comfort during low-intensity activities.
[0064] When a user's metabolic rate falls between a first threshold and a second threshold, their exercise intensity is classified as Level 2, i.e., moderate-intensity exercise. For example, the metabolic rate range for moderate-intensity exercise is 4.8–7.1 Met, with the first threshold being 4.7 Met. Exercise below this threshold is considered low intensity, while exercise above this threshold but below the second threshold is considered moderate intensity.
[0065] During moderate-intensity exercise, the body's need for ambient humidity increases. Prioritizing humidity adjustment can effectively alleviate the heat load generated by exercise. At the same time, maintaining an appropriate airflow speed works together to improve thermal comfort. When the metabolic rate crosses the first threshold but does not reach the second threshold, it is identified as a moderate-intensity exercise state. In this case, ambient humidity is adjusted first, while airflow speed and temperature are monitored to ensure that the indoor air humidity is appropriate, thereby achieving the optimal comfort environment.
[0066] When a user's metabolic rate exceeds the second threshold, their exercise intensity level is classified as Level 3, i.e., high-intensity exercise. For example, the metabolic rate range for high-intensity exercise is >7.2 Met, and the second threshold is 7.1 Met. Exceeding this value is classified as high-intensity exercise.
[0067] During high-intensity exercise, the body's demand for ambient temperature and humidity increases dramatically. Prioritizing temperature adjustment can quickly respond to changes in exercise load, and combined with humidity management, they work together to improve thermal comfort. When the metabolic rate exceeds the second threshold, the body's heat dissipation demand increases sharply. Immediately prioritizing temperature adjustment, along with humidity adjustment, ensures that the indoor environment can quickly adapt under high-intensity exercise conditions, reducing thermal stress on athletes and improving overall athletic performance and safety.
[0068] Specifically, the impact of various environmental parameters on human thermal comfort varies depending on the intensity of exercise. At low intensity, thermal comfort is significantly affected by wind speed; at moderate intensity, relative humidity and wind speed significantly influence thermal comfort; and at high intensity, ambient temperature and humidity significantly affect thermal sensation. In general, as exercise intensity increases, metabolism and blood flow accelerate, leading to increased oxygen consumption and perspiration, making it easier to feel "hot." At this point, ambient temperature and humidity have a greater impact on human comfort. Based on the association's experimental data, Table 1 shows the correlation between exercise intensity and metabolic rate.

[0071]
[0072] In some embodiments, controlling the air conditioner to operate according to the adjusted control parameters can be achieved through one of the following steps: When the adjusted control parameters include adjusted fan speed, adjusted temperature, and adjusted humidity, and the user's exercise intensity level is the first level, the air conditioner is controlled to operate according to the adjusted control parameters in a first sequence until the human body's thermal sensation value reaches a preset value. The first sequence is to first adjust the adjusted fan speed, then adjust the adjusted temperature, and then adjust the adjusted humidity. The human body's thermal sensation value is the user's perceived temperature in the environment. When the adjusted control parameters include the adjusted fan speed, adjusted temperature, and adjusted humidity, and the user's exercise intensity level is the first level, the air conditioner is controlled to operate according to the adjusted control parameters in a first sequence until the human body's thermal sensation value reaches a preset value. When the user's activity level is at the second level, the air conditioner is controlled to operate in the second sequence according to the adjusted control parameters until the human body's thermal sensation value reaches the preset value. The second sequence is to adjust the adjusted humidity first, then the adjusted fan speed, and then the adjusted temperature. When the adjusted control parameters include the adjusted fan speed, the adjusted temperature, and the adjusted humidity, and the user's activity level is at the third level, the air conditioner is controlled to operate in the third sequence according to the adjusted control parameters until the human body's thermal sensation value reaches the preset value. The third sequence is to adjust the adjusted humidity first, then the adjusted temperature, and then the adjusted fan speed.
[0073] This solution employs a first-order operation strategy to quickly and effectively improve thermal comfort in low-intensity exercise environments. Particularly at the start of exercise, prioritizing wind speed adjustments provides an immediate sense of comfort, laying a solid foundation for subsequent temperature and humidity adjustments. The second-order operation strategy precisely controls humidity and wind speed in medium-intensity exercise environments, effectively enhancing thermal comfort and exercise efficiency. The third-order operation strategy effectively controls humidity and temperature in high-intensity exercise environments, ensuring the safety and comfort of athletes during high-intensity activities while reducing energy waste and achieving energy conservation and emission reduction.
[0074] For low-intensity exercise, the human body is most sensitive to wind speed, followed by temperature, and lastly humidity. Therefore, when an exerciser's intensity level is Level 1 (low-intensity exercise), the air conditioning is controlled in the first order: first adjusting the wind speed, then the temperature, and finally the humidity, to achieve the preset thermal comfort values. This strategy fully utilizes the immediate effect of wind speed on thermal comfort; adjusting the wind speed first quickly improves thermal comfort, and then adjusting the temperature and humidity based on the exerciser's thermal comfort feedback ensures that the overall environmental parameters reach the optimal thermal comfort state.
[0075] During low-intensity exercise, the human body mainly relies on natural convection and radiation to dissipate heat. Adjusting the wind speed can significantly affect the efficiency of heat loss, thereby directly affecting thermal sensation. By first adjusting the wind speed to a preset value, the immediate effect of wind speed adjustment can be used to quickly improve thermal comfort. Then, based on feedback from the thermal comfort model, the temperature and humidity can be gradually adjusted to ultimately reach the preset thermal sensation value and create the best indoor thermal comfort environment.
[0076] For moderate-intensity exercise, the human body is more sensitive to humidity than to wind speed, and more sensitive to wind speed than to temperature. Therefore, when an exerciser's intensity level is level two (moderate-intensity exercise), the air conditioner operates in the second order: first adjusting humidity, then fan speed, and finally temperature, until the body's perceived thermal comfort level reaches the preset value. This operating strategy takes into account the body's needs for sweating and evaporative cooling during moderate-intensity exercise. It optimizes evaporative cooling efficiency by adjusting humidity, then assists in heat dissipation by adjusting fan speed, and finally ensures overall thermal comfort by adjusting temperature.
[0077] During moderate-intensity exercise, the body sweats more and becomes more sensitive to ambient humidity. First, adjust the humidity to a preset value to optimize the environment for sweat evaporation and heat dissipation. Then, adjust the fan speed to enhance sweat evaporation. Finally, adjust the temperature according to the thermal comfort model to ensure that the indoor environment meets the optimal thermal comfort requirements for moderate-intensity exercise, thereby improving exercise efficiency and experience.
[0078] During high-intensity exercise, the human body has the most pressing needs for ambient temperature and humidity, while its need for wind speed is relatively low. Therefore, when an exerciser's intensity level is level three, the third priority is given to adjusting humidity first, followed by temperature, and finally wind speed, until the human body's thermal sensation reaches the preset thermal comfort target. This control strategy ensures that during high-intensity exercise, the indoor environment can quickly adapt to the body's needs for heat dissipation and recovery, avoiding the risks of heat stress and dehydration during exercise.
[0079] During high-intensity exercise, the body's metabolism accelerates, body temperature rises, and the body becomes more dependent on regulating ambient temperature and humidity. First, humidity is adjusted to ensure unrestricted sweat evaporation. Then, the temperature is adjusted to a suitable level to maintain stable core body temperature. Finally, the fan speed is adjusted based on a comprehensive thermal comfort model to ensure optimal thermal comfort during high-intensity exercise. Simultaneously, the dynamic balance between indoor and outdoor temperatures is considered to avoid energy waste caused by excessive cooling or heating.
[0080] Specifically, when athletes exercise indoors, they often wear sports watches to monitor their performance. The parameters related to the human body in the thermal comfort model are skin temperature (T0). sk and heart rate N hr Both of these parameters can be collected by the fitness tracker. Ambient temperature, humidity, and wind speed can be collected by the 6533-2G smart environmental testing instrument.
[0081] First, the metabolic rate of people in the area is calculated using information collected by the fitness tracker to determine the intensity of their exercise.
[0082] If the exercise intensity level of the athlete is low, the ambient wind speed should be adjusted first. If adjusting the wind speed alone cannot make the SPTCM value 0, the ambient temperature should be adjusted. If that is still not enough, the ambient humidity should be adjusted last.
[0083] If the athlete's exercise intensity level is moderate, the ambient humidity should be adjusted first. If adjusting the humidity alone cannot make the SPTCM value 0, then the ambient wind speed should be adjusted. If that is still not enough, then the ambient temperature should be adjusted last.
[0084] If the athlete's exercise intensity level is high, the ambient humidity should be adjusted first. If adjusting the humidity alone cannot make the SPTCM value 0, then the ambient temperature should be adjusted. If that is still not enough, then the ambient wind speed should be adjusted last.
[0085] In general, adjusting the first two parameters can meet the needs of athletes for optimal comfort.
[0086] Specifically, the present application proposes an intelligent control method for air conditioners based on the optimal thermal comfort of athletes. According to the different exercise intensities of athletes, it is known that the influence of wind speed, humidity and temperature on athletes under different exercise intensities is different, and the demand for environmental parameters that need to be changed is also different. The indoor environmental parameters should be controlled in a given order according to the exercise intensity to ensure that the optimal thermal comfort of athletes under the current exercise state is met in the best way.
[0087] In the specific implementation process, before adjusting the initial control parameters according to the exercise intensity level to obtain the adjusted control parameters, the method further includes the following steps: calculating relevant parameters, wherein the relevant parameters include one or more of the user's skin temperature, the user's heart rate, the ambient temperature value in the exercise venue, the ambient humidity value in the exercise venue, and the ambient wind speed value in the exercise venue; calculating the weighted average of multiple relevant parameters to obtain the human body thermal sensation value.
[0088] This approach, by comprehensively considering and calculating multiple parameters related to thermal comfort, can more accurately assess the indoor thermal environment, providing a scientific basis for subsequent adjustments to control parameters and ensuring optimized thermal comfort. By calculating a weighted average, it can accurately reflect the overall thermal comfort needs of athletes at specific exercise intensities, providing a crucial reference for regulating air conditioning.
[0089] The calculation of multiple parameters can comprehensively reflect the heat exchange state between the human body and the environment. A comprehensive consideration of real-time physiological parameters such as skin temperature and heart rate, as well as environmental parameters such as ambient temperature, humidity, and wind speed, allows for a more accurate understanding and prediction of changes in human thermal sensation. This guides the air conditioning system to respond in a timely manner and adjust to the optimal thermal comfort environment. This comprehensive assessment and calculation ensures the accuracy and efficiency of air conditioning control, avoiding environmental discomfort or energy waste that might result from adjusting a single parameter.
[0090] The weighted average is calculated based on the Spatial Thermal Comfort Model (SPTCM), which integrates the influence of human physiological parameters and environmental factors on thermal sensation. The weights of each parameter are determined through multiple linear regression analysis. The weights of each parameter are dynamically adjusted according to the intensity of exercise. For example, wind speed has a relatively high weight during low-intensity exercise, while temperature and humidity have significantly increased weights during high-intensity exercise. This flexible weighting allows the SPTCM value to more accurately reflect the thermal sensation under current environmental conditions, guiding the air conditioning system to make optimal adjustments and ensure the thermal comfort of exercisers.
[0091] Specifically, this proposal suggests a sports personnel thermal comfort model (SPTCM) to assess a person's thermal perception of the environment during exercise. The model's input parameter is the current human skin temperature T. sk Human heart rate N hr Ambient temperature T in Ambient relative humidity N eh and ambient wind speed v e The output is the human thermal sensation value (SPTCM), and the specific calculation formula is as follows:
[0092] SPTCM=w0+w1T sk +w2N hr +w3T in +w4N eh +w5v e ;
[0093] In the formula, w0 is a constant value, w1, w2, w3, w4, and w5 represent the weights of the corresponding variables. When SPTCM is 0, it means that the temperature in the current environment is the optimal thermal sensation temperature for the athlete. When SPTCM is greater than 0, it means that the temperature is too high and the athlete feels hot. When SPTCM is less than 0, it means that the ambient temperature is too low and the athlete feels cold.
[0094] Information on SPTCM-related parameters of multiple participants during exercise was obtained in advance through experiments. Multiple linear regression was used to fit the relationship between the input and output parameters to determine the specific values of w0, w1, w2, w3, w4, and w5. Since the exercise intensity was divided into three levels, three different sets of results were obtained.
[0095] In some embodiments, controlling the air conditioner to operate according to the adjusted control parameters can be achieved through the following steps: obtaining the heat exchange efficiency of the air conditioner; calculating the optimal value of the operating power of the air conditioner based on the heat exchange efficiency, wherein the optimal value of the operating power of the air conditioner is used to ensure that the indoor temperature meets the user's comfort while saving energy and reducing emissions; and controlling the air conditioner to operate according to the adjusted control parameters based on the optimal value of the operating power of the air conditioner.
[0096] In this scheme, heat exchange efficiency is the foundation for evaluating whether an air conditioner can effectively respond to changes in indoor temperature. Under different operating intensities, the rate of change in indoor temperature and the required control range vary. Accurate heat exchange efficiency information helps the system calculate the optimal operating power value that can quickly respond to changes in indoor temperature demand while minimizing energy consumption, thus achieving a dual optimization of comfort and energy saving. Through the matching degree analysis between heat exchange efficiency and indoor temperature demand, an air conditioner operating power value that can effectively maintain the ideal indoor temperature while maximizing energy savings can be calculated. This value depends on the dynamic balance between heat exchange efficiency, indoor temperature target, and energy saving target. Once the optimal operating power is determined, the air conditioner can be guided to operate at this power, achieving the best combination of thermal comfort and energy saving and emission reduction. The determination of the optimal operating power considers the air conditioner's heat exchange efficiency, indoor temperature change demand, energy saving target, and heat exchange with the external environment, representing an economically optimal decision made while ensuring indoor thermal comfort. When the air conditioner operates at this optimal power, it can reach and stabilize the ideal indoor temperature and humidity levels in the shortest time with the lowest energy consumption. At the same time, by adjusting the fan speed appropriately, it can further improve thermal comfort, demonstrating the system's high level of intelligence and energy-saving performance.
[0097] Specifically, taking summer cooling as an example, when an air conditioner adjusts one of its parameters—humidity, temperature, or fan speed—other parameters also change accordingly, making precise control of the indoor environment difficult. Furthermore, when a temperature is set for the air conditioner, if the temperature sensor detects that the temperature near the air conditioner has reached the set value, it will not cool at a lower temperature, resulting in a deviation between the actual ambient temperature and the air conditioner's set temperature. Therefore, this solution proposes an air conditioner control scheme that starts with the air conditioner's cooling efficiency (i.e., heat exchange efficiency). By controlling the air conditioner's cooling power (i.e., operating power), and considering factors such as ambient humidity, temperature, fan speed, and heat exchange with the outdoor environment, a differential equation model of heat exchange efficiency is established.
[0098] Since heat exchange occurs due to the temperature difference between indoors and outdoors, the effect of outdoor heat on indoor air during time period t can be expressed as:
[0099]
[0100] In the formula, Q t T represents the heat exchange efficiency between indoors and outdoors during time period t. t in T t out Let t represent the indoor and outdoor temperatures respectively, R represent the thermal resistance of the building materials, and h represent the outdoor temperature. t in h tout f(N) represents the indoor convective heat transfer coefficient and the outdoor temperature convective heat transfer coefficient under dry conditions (relative humidity close to 0) for time period t. eh ) represents the effect of humidity on the convective heat transfer coefficient, where f(N) eh ) = 1 + 0.02N eh For ease of representation, let Q be defined. t The denominator in the calculation formula uses R. h The symbols are represented as follows:
[0101]
[0102] The formula for calculating the convective heat transfer coefficient is shown below. Where, h t V represents the convective heat transfer coefficient during time period t, where k is a proportionality constant, typically taken as 12.1. e It refers to ambient wind speed.
[0103]
[0104] When the air conditioner is cooling, in order to ensure that the indoor temperature, humidity, and fan speed are within the set range, the cooling capacity supplied to the indoor air by the air conditioner is Q. t air ·Δt, at which point the change in indoor temperature must satisfy the following differential relationship. Where, Q t air The value represents the cooling power of the air conditioner, measured in kW, while C represents the specific heat capacity of air, measured in J / (kg·℃).
[0105]
[0106] Discretizing the above differential equation yields:
[0107]
[0108] According to the formula for indoor and outdoor heat exchange, indoor ambient temperature is affected by humidity and wind speed. When adjusting a parameter of an air conditioner based on the SPTCM thermal comfort model, its impact on other environmental factors must be considered. It should be noted that when adjusting indoor humidity, it is generally achieved through cooling or dehumidification modes.
[0109] Therefore, when regulating the air conditioner according to the environmental control logic, it is necessary to adjust the air conditioner's cooling power Q. t air Appropriate controls should be implemented. When adjusting the operating parameters of an air conditioner, the fan speed responds the fastest, and once the fan speed is determined, it is basically unaffected by humidity and temperature. However, when adjusting temperature or humidity, the correlation between the two is relatively strong.
[0110] When people are engaged in low-intensity activities indoors, the ambient airflow needs to be adjusted to ensure optimal thermal comfort. When the ambient airflow changes due to air conditioner control, according to the differential equation model of heat exchange, an increase in airflow will increase the cooling capacity provided by the air conditioner, thus causing a change in indoor temperature.
[0111] Therefore, to maintain the original indoor temperature after a change in wind speed, the cooling capacity of the air conditioner needs to be adjusted. As shown in the discretized differential equation, the indoor ambient temperature gradually changes over time after a wind speed change. By monitoring the current indoor and outdoor environmental parameters, all parameters on the right side of the discretized equation can be obtained, while the temperature on the left side of the equation represents the original temperature T that needs to be maintained. t in Solving the equation yields the cooling power Q of the air conditioner. t air Adjust the cooling power of the air conditioner to the calculated value Q. t air To maintain the optimal thermal comfort environment for athletes; if adjusting the wind speed alone cannot meet the optimal thermal comfort requirements, then an optimal comfort environment for the airflow v is calculated based on the SPTCM model. e With temperature T in The solution involves solving the discretized equations after the wind speed adjustment is complete to calculate the indoor ambient temperature from the current temperature T. t in Change to the new indoor temperature T in The required cooling capacity Q of the air conditioner t air When the temperature is adjusted to T in Then, the discretized equations need to be solved again to update the relevant environmental parameters on the right side of the equations. The temperature on the left side of the equations is the current indoor temperature. The new cooling power Q of the air conditioner to maintain the current indoor temperature is then calculated. t air' Adjust the air conditioner's cooling power to this value to maintain the optimal thermal comfort environment for the athletes.
[0112] When people indoors are engaged in activities at a moderate intensity, the ambient humidity needs to be prioritized to ensure optimal thermal comfort. If the target humidity is within the air conditioner's adjustable range, the air conditioner will activate dehumidification mode to prioritize reaching the set humidity level. During dehumidification, the air conditioner's primary goal is to remove moisture from the air; the evaporator absorbs relatively little heat, thus having a minimal impact on the ambient temperature. Once the humidity reaches the optimal comfort level, the air conditioner will switch back to cooling mode. After switching back to cooling mode, according to the heat exchange differential equation model, the indoor temperature will gradually change over time due to the change in humidity. Therefore, the air conditioner's cooling power needs to be controlled to maintain the current indoor temperature. By monitoring the current indoor and outdoor environmental parameters, all parameters on the right-hand side of the discretized equation can be obtained, while the temperature on the left-hand side represents the original temperature T to be maintained. t in Solving the equation yields the cooling power Q of the air conditioner. t air Adjust the cooling power of the air conditioner to the calculated value Q. t air To maintain the optimal thermal comfort environment for current athletes.
[0113] If the humidity is outside the adjustable range of the air conditioner, then calculate a set of optimal comfort environment airflow v based on the SPTCM model. e With humidity N eh The solution is to first switch the air conditioner to dehumidification mode, and then use this mode to adjust the indoor humidity to the calculated value N. eh After adjusting the humidity, switch the air conditioner back to cooling mode and then adjust the fan speed to the calculated value v. e Since the indoor temperature and humidity have changed, the cooling capacity of the air conditioner needs to be adjusted to maintain the original indoor temperature. By monitoring the indoor and outdoor environmental parameters at the current moment, all parameters on the right side of the discretized equation are obtained, and the temperature on the left side of the equation is the original temperature T that needs to be maintained. t in Solving the equation yields the cooling power Q of the air conditioner. t air Adjust the cooling power of the air conditioner to the calculated value Q. t air To maintain the optimal thermal comfort environment for current athletes.
[0114] When people indoors engage in high-intensity activities, the ambient humidity needs to be prioritized for optimal thermal comfort. If the target humidity is within the air conditioner's adjustable range, the air conditioner activates dehumidification mode to bring the humidity to the set value. Once the humidity reaches the optimal comfort level, the air conditioner switches back to cooling mode. After switching back to cooling mode, according to the heat exchange differential equation model, the indoor temperature will gradually change over time due to the change in humidity. Therefore, the air conditioner's cooling power needs to be controlled to maintain the current indoor temperature. By monitoring the indoor and outdoor environmental parameters at the current moment, all parameters on the right-hand side of the discretized equation can be obtained, while the temperature on the left-hand side represents the original temperature T to be maintained. t in Solving the equation yields the cooling power Q of the air conditioner. t air Adjust the cooling power of the air conditioner to the calculated value Q. t air To maintain the optimal thermal comfort environment for current athletes.
[0115] If the humidity is outside the adjustable range of the air conditioner, then a set of optimal comfort environment temperatures T is calculated based on the SPTCM model. in With humidity N eh The solution is to first switch the air conditioner to dehumidification mode, and then use this mode to adjust the indoor humidity to the calculated value N. eh After humidity control is complete, switch the air conditioner back to cooling mode. Then, by solving the discretized equations, calculate the indoor ambient temperature from the current temperature T. t in Change to the new indoor temperature T in The required cooling capacity Q of the air conditioner t air When the temperature is adjusted to T in Then, the discretized equations need to be solved again to update the relevant environmental parameters on the right side of the equations. The temperature on the left side of the equations is the current indoor temperature. The new cooling power Q of the air conditioner to maintain the current indoor temperature is then calculated. t air' Adjust the air conditioner's cooling power to this value to maintain the optimal thermal comfort environment for the athletes.
[0116] Specifically, this application proposes an intelligent air conditioner control method for optimal comfort environment regulation. Based on the athlete's need for the current optimal thermal comfort environment, the air conditioner is adjusted to achieve the set value. Changes in indoor environmental parameters can increase or decrease the heat exchange between indoors and outdoors. To maintain a dynamic balance between indoor and outdoor temperatures, the cooling (heating) power of the air conditioner needs to be regulated to ensure that the indoor environment does not become too cold or too hot after the air conditioner has been running for a period of time.
[0117] In summary, the solution presented in this application can determine a person's needs for indoor temperature, humidity, and wind speed by analyzing their exercise intensity, and then adjust the air conditioning accordingly to improve the exercise effect of athletes in indoor sports venues. This addresses the user's needs for the indoor environment under different exercise intensities. The solution provided in this application allows different types of athletes to achieve optimal thermal comfort, has high applicability, and solves the problem of maintaining a dynamic balance between indoor and outdoor temperatures.
[0118] This application also provides a control device for air conditioning in sports venues. It should be noted that the control device for air conditioning in sports venues in this application can be used to execute the control method for air conditioning in sports venues provided in this application. This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.
[0119] The following describes the control device for air conditioning in sports venues provided in the embodiments of this application.
[0120] Figure 4 This is a structural block diagram of an air conditioning control device for a sports venue according to an embodiment of this application. Figure 4 As shown, the device includes:
[0121] The first control unit 10 is used to control the air conditioner to start operating according to the initial control parameters, wherein the initial control parameters are one or more of the initial set wind speed, initial set temperature and initial set humidity of the air conditioner in the sports venue.
[0122] The determining unit 20 is used to obtain the user's metabolic rate at the above-mentioned sports venue and determine the user's exercise intensity level based on the user's metabolic rate, wherein the user's metabolic rate and the exercise intensity level are positively correlated.
[0123] The adjustment unit 30 is used to adjust the initial control parameters according to the above-mentioned exercise intensity level to obtain the adjusted control parameters.
[0124] The second control unit 40 is used to control the air conditioner to operate according to the adjusted control parameters.
[0125] This embodiment demonstrates that, based on the different exercise intensity levels of athletes, the influence of environmental wind speed, humidity, and temperature varies depending on the exercise intensity level. This solution allows for personalized adjustments to the air conditioning based on the exercise intensity level of athletes in the sports venue, thereby improving the comfort of athletes and ultimately enhancing the user experience.
[0126] In the specific implementation process, the first control unit includes a first acquisition module, a first calculation module, a second acquisition module, and a first control module. The first acquisition module is used to acquire the skin temperature of all users; the first calculation module is used to calculate the average skin temperature of all users to obtain an average skin temperature value; the second acquisition module is used to acquire the ambient temperature value in the sports venue and the thermal resistance value of the clothing of the users; the first control module is used to determine the initial set temperature based at least on the average skin temperature value, the ambient temperature value, and the thermal resistance value of the clothing, and control the air conditioner to start operating at least at the initial set temperature, wherein the average skin temperature value and the initial set temperature are negatively correlated, the ambient temperature value and the initial set temperature are negatively correlated, and the thermal resistance value of the clothing is positively correlated with the initial set temperature.
[0127] In this scheme, the skin temperature information of all athletes provides direct feedback on their perceived ambient temperature, which helps to build a more accurate thermal comfort model. This guides the optimization and adjustment of parameters. The use of average skin temperature values enhances the objectivity and accuracy of thermal comfort assessment, allowing for dynamic adjustment of the initial set temperature based on the actual conditions within the sports venue to achieve higher comfort standards. By comprehensively considering ambient temperature and clothing thermal resistance, the initial set temperature can be adjusted according to actual conditions, ensuring optimal thermal comfort for athletes even under variable environmental conditions. Based on the parameter relationships in the simplified PMV model, a negative correlation between average skin temperature and initial set temperature, a negative correlation between ambient temperature and initial set temperature, and a positive correlation between clothing thermal resistance and initial set temperature can be derived. Through calculations using this model, the initial set temperature can be adjusted more precisely, ensuring that the indoor environment meets human thermal comfort requirements while avoiding energy waste, achieving efficient and personalized thermal comfort control.
[0128] In some embodiments, the determining unit includes a first determining module, a second determining module, and a third determining module. The first determining module is used to acquire the heart rate of a user when the number of users in the aforementioned sports venue is 1, and to determine the user's metabolic rate based on the heart rate, wherein the heart rate and the user's metabolic rate are positively correlated. The second determining module is used to acquire the heart rate of each user when the number of users in the aforementioned sports venue is greater than 1 and all users are of the same gender, to determine the metabolic rate of each user based on the heart rate of each user, and to calculate the average of the metabolic rates of all users to obtain the user's metabolic rate. The third determining module is used to acquire the heart rate of each user when the number of users in the aforementioned sports venue is greater than 1 and all users have two genders, to determine the metabolic rate of each user based on the gender and the heart rate of each user, and to calculate the average of the metabolic rates of all users to obtain the user's metabolic rate, wherein the metabolic rates of males and females are different.
[0129] This solution leverages the positive correlation between heart rate monitoring and metabolic rate calculation to directly adjust the metabolic rate of exercisers in real time based on heart rate changes. This allows for customized environmental adjustments at different exercise intensities, enhancing thermal comfort. When the group is of the same gender, the average metabolic rate calculation reflects overall thermal comfort needs. By converting heart rate to metabolic rate, air conditioning parameters can be adjusted based on the average metabolic rate, ensuring all users experience suitable thermal comfort. Considering the difference in metabolic rates between men and women at the same heart rate, calculating separately and then averaging allows for a more detailed assessment of the group's thermal comfort needs, ensuring that indoor environmental parameter adjustments consider the comfort of all individuals.
[0130] In the specific implementation process, the determining unit includes a fourth determining module, a fifth determining module, and a sixth determining module. The fourth determining module is used to determine the user's exercise intensity level as a first level when the user's metabolic rate is less than a first threshold. The fifth determining module is used to determine the user's exercise intensity level as a second level when the user's metabolic rate is greater than or equal to the first threshold and less than a second threshold, wherein the first threshold is less than the second threshold and the exercise intensity of the first level is lower than that of the second level. The sixth determining module is used to determine the user's exercise intensity level as a third level when the user's metabolic rate is greater than or equal to the second threshold, wherein the exercise intensity of the second level is lower than that of the third level.
[0131] This solution accurately distinguishes low-intensity exercise by setting a first threshold, providing users with appropriate adjustment plans and enhancing comfort. Setting a second threshold promptly identifies medium-intensity exercise, offering users suitable adjustment plans and further strengthening personalized comfort management. By setting a second threshold and identifying high-intensity exercise, it provides users with appropriate adjustment plans, offering an optimal thermal comfort environment, especially during strenuous exercise, effectively preventing heat stress and fatigue accumulation.
[0132] In some embodiments, the second control unit includes a second control module, a third control module, and a fourth control module. The second control module is used to control the air conditioner to operate in a first sequence according to the adjusted control parameters, including the adjusted wind speed, adjusted temperature, and adjusted humidity, and the user's exercise intensity level is the first level, until the human body's thermal sensation value reaches a preset value. The first sequence is to adjust the adjusted wind speed first, then the adjusted temperature, and then the adjusted humidity. The human body's thermal sensation value is the user's perceived temperature in the environment. The third control module is used to control the air conditioner to operate in a first sequence according to the adjusted control parameters, including the adjusted wind speed, adjusted temperature, and adjusted humidity, and the user's exercise intensity level is the first level. When the user's activity level is the second level, the air conditioner is controlled to operate in the second sequence according to the adjusted control parameters until the human body's thermal sensation value reaches the preset value. The second sequence is to adjust the adjusted humidity first, then the adjusted fan speed, and then the adjusted temperature. The fourth control module is used to control the air conditioner to operate in the third sequence according to the adjusted control parameters when the adjusted control parameters include the adjusted fan speed, the adjusted temperature, and the adjusted humidity, and the user's activity level is the third level. The third sequence is to adjust the adjusted humidity first, then the adjusted temperature, and then the adjusted fan speed.
[0133] This solution employs a first-order operation strategy to quickly and effectively improve thermal comfort in low-intensity exercise environments. Particularly at the start of exercise, prioritizing wind speed adjustments provides an immediate sense of comfort, laying a solid foundation for subsequent temperature and humidity adjustments. The second-order operation strategy precisely controls humidity and wind speed in medium-intensity exercise environments, effectively enhancing thermal comfort and exercise efficiency. The third-order operation strategy effectively controls humidity and temperature in high-intensity exercise environments, ensuring the safety and comfort of athletes during high-intensity activities while reducing energy waste and achieving energy conservation and emission reduction.
[0134] In the specific implementation process, the above-mentioned device also includes a first calculation unit and a second calculation unit. The first calculation unit is used to calculate relevant parameters before adjusting the initial control parameters according to the exercise intensity level to obtain the adjusted control parameters. The relevant parameters include one or more of the user's skin temperature, the user's heart rate, the ambient temperature value in the exercise venue, the ambient humidity value in the exercise venue, and the ambient wind speed value in the exercise venue. The second calculation unit is used to calculate the weighted average of multiple of the above-mentioned relevant parameters to obtain the human body thermal sensation value.
[0135] This approach, by comprehensively considering and calculating multiple parameters related to thermal comfort, can more accurately assess the indoor thermal environment, providing a scientific basis for subsequent adjustments to control parameters and ensuring optimized thermal comfort. By calculating a weighted average, it can accurately reflect the overall thermal comfort needs of athletes at specific exercise intensities, providing a crucial reference for regulating air conditioning.
[0136] In some embodiments, the second control unit includes a third acquisition module, a second calculation module, and a fifth control module. The third acquisition module is used to acquire the heat exchange efficiency of the air conditioner. The second calculation module is used to calculate the optimal value of the operating power of the air conditioner based on the heat exchange efficiency. The optimal value of the operating power of the air conditioner is used to ensure that the indoor temperature meets the user's comfort while saving energy and reducing emissions. The fifth control module is used to control the air conditioner to operate according to the adjusted control parameters based on the optimal value of the operating power of the air conditioner.
[0137] In this scheme, heat exchange efficiency is the foundation for evaluating whether an air conditioner can effectively respond to changes in indoor temperature. Under different operating intensities, the rate of change in indoor temperature and the required control range vary. Accurate heat exchange efficiency information helps the system calculate the optimal operating power value that can quickly respond to changes in indoor temperature demand while minimizing energy consumption, thus achieving a dual optimization of comfort and energy saving. Through the matching degree analysis between heat exchange efficiency and indoor temperature demand, an air conditioner operating power value that can effectively maintain the ideal indoor temperature while maximizing energy savings can be calculated. This value depends on the dynamic balance between heat exchange efficiency, indoor temperature target, and energy saving target. Once the optimal operating power is determined, the air conditioner can be guided to operate at this power, achieving the best combination of thermal comfort and energy saving and emission reduction. The determination of the optimal operating power considers the air conditioner's heat exchange efficiency, indoor temperature change demand, energy saving target, and heat exchange with the external environment, representing an economically optimal decision made while ensuring indoor thermal comfort. When the air conditioner operates at this optimal power, it can reach and stabilize the ideal indoor temperature and humidity levels in the shortest time with the lowest energy consumption. At the same time, by adjusting the fan speed appropriately, it can further improve thermal comfort, demonstrating the system's high level of intelligence and energy-saving performance.
[0138] The air conditioning control device in the aforementioned sports venue includes a processor and a memory. The first control unit, determining unit, adjusting unit, and second control unit are all stored as program units in the memory, and the processor executes the program units stored in the memory to achieve the corresponding functions. All of the above modules are located in the same processor; alternatively, the various modules may be located in different processors in any combination.
[0139] The processor contains a kernel, which retrieves the corresponding program units from memory.
