Description

Technical Field

[0001] The present invention relates to the technical field of linkage control of air conditioners and windows, and in particular to a linkage control method and system of air conditioners and intelligent windows. Background Art

[0002] In modern buildings and home environments, the linkage control of air conditioners and windows faces many challenges. The traditional operation method requires users to manually check whether the windows are closed before turning on the air conditioner to avoid the loss of cold or warm air, increase energy consumption, reduce air conditioning efficiency, and even damage the equipment due to forgetting to close the windows. Although some products have realized simple linkage functions, such as automatically closing windows when the air conditioner is turned on, this basic linkage cannot be intelligently adjusted according to the real-time changes in the indoor and outdoor environments. The functions are single and cannot meet the user's higher requirements for comfort and energy saving. Long-term use of air conditioners will cause indoor air to be dry and stagnant, affecting health and comfort. The traditional window opening and ventilation method cannot effectively cooperate with air conditioners, resulting in large indoor temperature fluctuations and poor user experience. In addition, the existing linkage system has limited energy-saving measures and cannot perform intelligent energy-saving control according to changes in the indoor and outdoor environments and user habits, resulting in serious energy waste and increasing the economic and environmental burdens of users. Summary of the invention

[0003] In view of the above-mentioned defects, the purpose of the present invention is to propose a method and system for linkage control of air conditioners and smart windows, aiming to solve the problems of inconvenient operation and insufficient comfort adjustment in traditional technologies, combine air conditioning with the environment, increase user comfort and reduce energy consumption of air conditioning adjustment.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0014] When the temperature of the external wind is within the user's desired body temperature range, a first air exchange duration is obtained according to the current wind speed of the external wind, the window opening and the target air exchange volume;

[0015] The target ventilation time is compared with the first ventilation time. If the first ventilation time is less than the target ventilation time, the window opening is increased and the wind speed of the external wind is continuously monitored. The second ventilation time after the window opening is changed is calculated until the wind speed of the external wind at the window is equal to the maximum value of the wind speed range required by the user or the second ventilation time is equal to the target ventilation time;

[0016] If the first air change duration is greater than the target air change duration, reduce the window opening and continue to monitor the wind speed of the outside wind, and calculate the third air change duration after the window opening changes, until the wind speed of the outside wind at the window is equal to the minimum value of the user's required body-felt wind speed range or the third air change duration is equal to the target air change duration.

[0017] Further, when the temperature of the external wind is outside the user's desired sensible temperature range, if the temperature of the external wind is greater than the maximum value of the user's desired sensible temperature range, then when the wind speed of the external wind is within the user's desired sensible wind speed range, the window opening is reduced;

[0018] When adjusting the window opening, the air outlet temperature of the air conditioner is adjusted according to the difference between the temperature of the external wind at this time and the maximum value of the body temperature range required by the user, and the fourth air exchange time is obtained according to the wind speed of the external wind at this time, the window opening and the target air exchange volume;

[0019] According to the difference between the fourth air exchange duration and the target air exchange duration, increasing or decreasing the air outlet speed of the air conditioner within the range of perceived wind speed required by the user;

[0020] If the temperature of the outside wind is less than the minimum value of the user's desired temperature range, the window opening is increased when the wind speed of the outside wind is within the user's desired wind speed range;

[0022] According to the difference between the fifth air exchange duration and the target air exchange duration, the air outlet speed of the air conditioner is increased or decreased within the body-felt wind speed range required by the user.

[0023] Preferably, the window opening is first adjusted according to the operation mode, the wind speed and / or temperature of the external wind, and the user's desired temperature range and / or wind speed range, satisfying the relationship:

[0024]

[0025] Where θ represents the window opening, Q target air volume represents the target air volume, A windows represents the total area of ​​windows, V wind speed represents the wind speed of the external wind, H humidity represents the relative humidity of the air, and T 1 Indicates the temperature of the external wind at the current window, T 2 represents the median value of the temperature range required by the user, and ΔT represents the temperature range required by the user.

[0026] Preferably, in the blowing mode, the second adjustment of the operating parameters of the air conditioner and / or the window opening according to the user's spatial position, the window position, the air conditioner position, the wind direction of the external wind and the operating mode includes:

[0027] A parallel plane is made at the user's location to the wall where the window is located, and when the air conditioner and the window are on different sides of the parallel plane, it is determined whether the wind speed of the external wind at the window is within the range of the user's required wind speed;

[0028] If not, adjust the window opening until the wind speed of the outside wind at the window is within the user's desired perceived wind speed range;

[0029] If so, the air outlet speed of the air conditioner is set to be the same as the wind speed of the external wind at the window, and the air outlet direction of the air conditioner is adjusted to be parallel to the wind direction of the external wind and in the opposite direction.

[0030] Preferably, in the blowing mode, the second adjustment of the operating parameters of the air conditioner and / or the window opening according to the user's spatial position, the window position, the air conditioner position, the wind direction of the external wind and the operating mode includes:

[0031] Draw a parallel plane to the wall where the window is located at the user's location. When the air conditioner and the window are on different sides of the parallel plane:

[0032] A plane rectangular coordinate system is made with the center point of the opened part of the window as the origin, the horizontal direction as the X axis, and the vertical direction as the Y axis, and the quadrants where the upper right corner, upper left corner, lower left corner and lower right corner of the window are located are set as the first to fourth quadrants respectively;

[0033] Calculate the areas of the wall where the window is located in the first quadrant to the fourth quadrant as the first area to the fourth area respectively;

[0034] According to the first to fourth areas, calculating the area ratios of the remaining three quadrants except the quadrant to which the wind direction of the external wind at the window points;

[0037] A parallel plane is made at the user's location to the wall where the window is located. When the air conditioner and the window are on the same side of the parallel plane, the wind speed of the external wind at the window is compared with the user's desired somatic wind speed range;

[0038] If the wind speed of the external wind at the window is less than the minimum value of the perceived wind speed range required by the user, the window opening is increased until the wind speed of the external wind enters the perceived wind speed range; if the wind speed of the external wind is always lower than the minimum value of the perceived wind speed range, the air conditioner is turned on to accelerate the external wind until the wind speed of the external wind is not lower than the minimum value of the perceived wind speed range;

[0039] If the wind speed of the external wind at the window is greater than the maximum value of the perceived wind speed range required by the user, the window opening is reduced until the wind speed of the external wind enters the perceived wind speed range.

[0040] Preferably, the spatial position of the user includes the distance between the user and the window;

[0041] When the wind speed of the external wind is within the perceived wind speed range and the temperature of the external wind is outside the perceived temperature range, comparing the distance between the user and the window with the adjustable distance;

[0042] If the distance between the user and the window is greater than the adjustable distance, the air outlet temperature of the air conditioner is adjusted according to the body temperature range according to the minimum difference between the temperature of the outside wind and the edge value of the body temperature range;

Obviously, the drawings described below are only embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

[0054] Figure 2 It is a structural schematic diagram of an air conditioner and smart window linkage control system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0055] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0056] In the present invention, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0057] The present invention proposes a linkage control method for air conditioner and smart window. Figure 1 As shown, in a preferred embodiment of the present invention, the linkage control method comprises the following steps:

[0058] S1: continuously obtaining the wind direction, wind speed and temperature of the external wind at the window;

[0059] In this embodiment, the control system or the system is provided with the air conditioner and smart window linkage control method proposed in the present invention. The system can be provided in the air conditioner or in an external controller, and can simultaneously control the opening and closing of windows, the adjustment of air conditioner operating parameters, and the acquisition of parameters through control signals.

[0060] In step S1, a wind direction sensor, a wind speed sensor, and a temperature sensor may be installed near the window. The wind direction sensor determines the direction of the wind by detecting the pressure change of the wind on the sensor surface; the wind speed sensor calculates the wind speed by measuring the impact force or vibration frequency of the wind on the sensor; the temperature sensor senses the temperature change of the surrounding air through thermistor and converts these changes into electrical signals. The sensor transmits the collected wind direction, wind speed, and temperature data to the air conditioner control system through wired or wireless communication. The control system processes and analyzes these data in real time to provide accurate environmental information basis for the subsequent linkage control of the air conditioner and the window.

[0061] S2: continuously acquiring the user's spatial location, and inputting demand information and the spatial location into the air conditioner, wherein the demand information includes the user's desired temperature range, wind speed range, operating mode and operating parameters of the air conditioner;

[0062] Using indoor positioning technologies, such as Wi-Fi positioning, Bluetooth positioning or ultrasonic positioning, the user's smartphone, wearable device or dedicated positioning tag communicates with the indoor positioning base station or signal source to calculate the user's specific location indoors. At the same time, through the user interface (such as mobile phone APP, voice assistant or remote control, etc.), the user can enter their own demand information, including the perceived temperature range, perceived wind speed range, air conditioner operation mode (such as cooling, heating, dehumidification, automatic, etc.) and specific operating parameters (such as temperature setting, wind speed setting, wind direction setting, etc.). The user interface converts this demand information into data signals and transmits it to the air conditioner control system. The control system provides user demand basis for subsequent air conditioner and window linkage control based on the user's spatial position and demand information.

[0063] S3: performing a first adjustment on the window opening according to the operation mode, the wind speed and / or temperature of the external wind, and the perceived temperature range and / or perceived wind speed range required by the user;

[0064] The control system calculates the appropriate window opening through a built-in intelligent algorithm based on the air conditioner's operating mode (such as ventilation mode, blowing mode or cooling mode, etc.), combined with the wind speed and temperature data of the outside wind at the window, as well as the user's required body temperature range and body wind speed range. For example, in ventilation mode, if the temperature of the outside wind is within the user's required body temperature range and the wind speed is moderate, the system will increase the window opening to introduce more fresh air; if the temperature of the outside wind is too high or too low, the system will reduce the window opening to reduce the impact on the indoor temperature. In blowing mode, the system will adjust the window opening according to the user's required body wind speed range so that the indoor wind speed meets the user's comfort requirements. Through this preliminary adjustment, the system can optimize indoor air circulation and temperature distribution, providing a basis for subsequent air conditioning adjustment.

[0065] S4: performing a second adjustment on the operating parameters of the air conditioner and / or the window opening according to the user's spatial position, the window position, the air conditioner position, the wind direction of the external wind and the operating mode;

[0066] Among them, the operating parameters of the air conditioner include the air outlet temperature, air outlet direction and air outlet speed of the air conditioner.

[0067] The control system comprehensively considers the user's spatial position, window position, air conditioner position, external wind direction and air conditioner operation mode, and further fine-tunes the air outlet temperature, air outlet direction and air outlet speed of the air conditioner, as well as the window opening. For example, if the user is close to the window and the wind direction of the external wind is opposite to the user, the system will adjust the air outlet direction of the air conditioner so that the airflow avoids the user and avoids direct blowing; at the same time, according to the user's required body temperature range, the air outlet temperature of the air conditioner is adjusted to compensate for the impact of external wind on the indoor temperature. If the user is away from the window, the system will increase the air outlet speed of the air conditioner so that the airflow can cover the area where the user is located. In addition, the system will dynamically adjust the window opening according to the wind direction and wind speed of the external wind to achieve the best ventilation effect and indoor comfort. Through this comprehensive adjustment, it is ensured that users can get an ideal body experience in different positions and under different environmental conditions, while reducing energy consumption and improving the level of intelligence.

[0068] Preferably, the operation mode of the air conditioner includes a ventilation mode and a blowing mode, wherein the ventilation mode is a mode for exchanging indoor air with outdoor air when the indoor air is relatively turbid. Different from the ventilation mode of ordinary air conditioners, the ventilation mode proposed by the present invention adds window ventilation, which can discharge the turbid gas or harmful gas in the room more quickly. The existing air conditioner not only has cooling and heating functions, but also has a blowing function similar to a fan. If the air conditioner is only relied on to blow, the power consumption of the air conditioner will increase. Assuming that the outdoor air flow rate is fast (such as autumn), the window air intake assists the air conditioning blowing or the air conditioning air intake assists the window air intake to achieve blowing for the user, which can save the energy consumption of the air conditioner. In addition, the operating parameters of the air conditioner can be changed. When the outdoor air intake (wind direction, wind speed or temperature, etc.) cannot be changed in a short time, adjusting the window opening and the operating parameters of the air conditioner can enable the user to maintain a stable and comfortable experience.

[0069] Preferably, in the ventilation mode, the demand information also includes a target ventilation volume and a target ventilation duration;

[0070] The first adjustment of the window opening according to the operation mode, the wind speed and / or temperature of the external wind, and the perceived temperature range and / or perceived wind speed range required by the user includes:

[0071] When the temperature of the external wind is within the user's desired body temperature range, a first air exchange duration is obtained according to the current wind speed of the external wind, the window opening and the target air exchange volume;

[0072] The target ventilation time is compared with the first ventilation time. If the first ventilation time is less than the target ventilation time, the window opening is increased and the wind speed of the external wind is continuously monitored. The second ventilation time after the window opening is changed is calculated until the wind speed of the external wind at the window is equal to the maximum value of the wind speed range required by the user or the second ventilation time is equal to the target ventilation time;

[0073] If the first air change duration is greater than the target air change duration, reduce the window opening and continue to monitor the wind speed of the outside wind, and calculate the third air change duration after the window opening changes, until the wind speed of the outside wind at the window is equal to the minimum value of the user's required body-felt wind speed range or the third air change duration is equal to the target air change duration.

[0074] In the ventilation mode, the user's demand information is first obtained, including the target air exchange volume and the target air exchange duration. The user clearly specifies the amount of indoor air that needs to be replaced per unit time (target air exchange volume) and the time required to complete this air exchange (target air exchange duration) through the input interface. The purpose is to enable the system to accurately control the exchange of indoor and outdoor air according to the user's specific needs, ensure that the indoor air quality meets the user's expected standards, and provide an important reference basis for the subsequent window opening adjustment.

[0075] The window opening is first adjusted according to the operating mode (air exchange mode) of the air conditioner, the speed and temperature of the outside wind at the window, and the perceived temperature range and perceived wind speed range required by the user. When the temperature of the outside wind is within the perceived temperature range set by the user, the first air exchange duration is calculated according to the current outside wind speed, the window opening and the target air exchange volume. The first air exchange duration can be calculated by dividing the target air exchange volume by the product of the effective area of ​​the window opening part and the outside wind speed. Specifically, the target air exchange volume refers to the amount of indoor air that needs to be replaced within the time set by the user, the effective area of ​​the window opening part refers to the area of ​​the actual window opening part, and the outside wind speed refers to the speed of the natural wind at the window. Through this calculation method, the time required to reach the target air exchange volume at the current window opening and outside wind speed can be obtained. If the calculated ventilation time is less than the target ventilation time set by the user, it means that the current window opening and outside wind speed cannot meet the user's ventilation needs, and the window opening needs to be increased; conversely, if the calculated ventilation time is greater than the target ventilation time, the window opening needs to be reduced to ensure that the actual ventilation time is consistent with the target set by the user, and at the same time make the outside wind speed at the window within the user's comfort range.

[0076] Assume that the target air change volume is 60 cubic meters per hour, the total window area is 2 square meters, the external wind speed is 2 meters per second, the window opening is 50%, the user's required perceived temperature range is 22 to 26 degrees Celsius, the perceived wind speed range is 0.2 to 0.5 meters per second, and the target air change duration is set to 30 minutes. First, calculate the first air change duration based on the current external wind speed, window opening and target air change volume. Divide the target air change volume by the product of the effective area of ​​the open part of the window (total window area multiplied by the opening coefficient) and the external wind speed to obtain the first air change duration of 60 minutes. Then compare the target air change duration with the first air change duration, and find that the first air change duration is greater than the target air change duration (60 minutes>30 minutes), indicating that the current window opening is too large, resulting in too fast air change. Therefore, it is necessary to reduce the window opening. Assuming that the window opening is reduced to 30%, the third air change duration is recalculated, and the result is 50 minutes. Continue to adjust the window opening until the third air change time is equal to the target air change time (30 minutes), while ensuring that the outside wind speed at the window is not lower than the minimum value of the user's required body-perceived wind speed range (0.2 meters per second), ultimately meeting the user's requirements for indoor air quality and comfort.

[0077] Preferably, when the temperature of the external wind is outside the user's desired somatic temperature range, if the temperature of the external wind is greater than the maximum value of the user's desired somatic temperature range, then when the wind speed of the external wind is within the user's desired somatic wind speed range, the window opening is reduced;

[0078] When adjusting the window opening, the air outlet temperature of the air conditioner is adjusted according to the difference between the temperature of the external wind at this time and the maximum value of the body temperature range required by the user, and the fourth air exchange time is obtained according to the wind speed of the external wind at this time, the window opening and the target air exchange volume;

[0079] According to the difference between the fourth air exchange duration and the target air exchange duration, increasing or decreasing the air outlet speed of the air conditioner within the range of perceived wind speed required by the user;

[0080] If the temperature of the outside wind is less than the minimum value of the user's desired temperature range, the window opening is increased when the wind speed of the outside wind is within the user's desired wind speed range;

[0081] When adjusting the window opening, the air outlet temperature of the air conditioner is adjusted according to the difference between the temperature of the external wind at this time and the minimum value of the body temperature range required by the user, and the fifth air exchange time is obtained according to the wind speed of the external wind at this time, the window opening and the target air exchange volume;

[0082] According to the difference between the fifth air exchange duration and the target air exchange duration, the air outlet speed of the air conditioner is increased or decreased within the body-felt wind speed range required by the user.

[0083] When the outside wind temperature at the window exceeds the maximum value of the user-set body temperature range, it means that the natural wind temperature is high. If a large amount of it enters the room, it will cause the indoor temperature to rise, making the user feel overheated. At this time, by reducing the window opening, the amount of high-temperature outside wind entering the room can be effectively reduced, thereby slowing down the rate of increase in indoor temperature. Reducing the window opening will reduce the area of ​​the open window, thereby reducing the air circulation, so that the impact of high-temperature wind on the indoor environment is weakened.

[0084] After reducing the window opening, the air outlet temperature of the air conditioner is adjusted according to the difference between the outside wind temperature and the maximum value of the user's perceived temperature range. If the outside wind temperature is much higher than the maximum value of the user's perceived temperature range, it means that the indoor temperature may rise rapidly. At this time, the air conditioner needs to provide a stronger cooling effect to offset the impact of the high temperature wind. Therefore, the air outlet temperature of the air conditioner needs to be lowered to speed up the reduction of the indoor temperature. On the contrary, if the outside wind temperature is only slightly higher than the maximum value of the user's perceived temperature range, it means that the indoor temperature rises slowly and the air conditioner only needs to cool moderately. Therefore, the system will appropriately increase the air outlet temperature to avoid energy waste caused by excessive cooling and the problem of too low indoor temperature.

[0085] After adjusting the window opening and the air outlet temperature of the air conditioner, the fourth air change duration is calculated according to the wind speed of the external wind, the window opening and the target air change volume at this time, and the fourth air change duration is compared with the target air change duration set by the user. If the fourth air change duration is shorter than the target air change duration, it means that the current air change speed is too fast, which may cause excessive fluctuations in the indoor temperature, which is not conducive to maintaining a stable indoor environment. At this time, reduce the air outlet speed of the air conditioner so that the air change speed is consistent with the target to maintain the stability of the indoor temperature. If the fourth air change duration is longer than the target air change duration, it means that the air change speed is too slow and cannot meet the needs of indoor air circulation. The system will increase the air outlet speed of the air conditioner and speed up the air change speed to improve the indoor air quality and ensure the freshness and comfort of the indoor air. When the outside wind temperature at the window is lower than the minimum value of the perceived temperature range set by the user, it means that the temperature of the natural wind is low. If a large amount of natural wind enters the room, it will cause the indoor temperature to drop, making the user feel too cold. At this time, by increasing the window opening, more low-temperature outside wind can be introduced, thereby lowering the indoor temperature and bringing the indoor temperature closer to the lower limit of the user's comfortable temperature range. Increasing the window opening will increase the area of ​​the open part of the window, thereby increasing the air circulation, allowing the low-temperature wind to enter the room more effectively and help lower the indoor temperature.

[0086] After increasing the window opening, the air outlet temperature of the air conditioner is adjusted according to the difference between the outside wind temperature and the minimum value of the user's perceived temperature range. If the outside wind temperature is much lower than the minimum value of the user's perceived temperature range, it means that the indoor temperature may drop rapidly. At this time, the air conditioner needs to provide a stronger heating effect to offset the impact of the low temperature wind. Therefore, the air outlet temperature of the air conditioner is increased to speed up the increase of the indoor temperature. On the contrary, if the outside wind temperature is only slightly lower than the minimum value of the user's perceived temperature range, it means that the indoor temperature drops slowly, and the air conditioner only needs to heat moderately. Therefore, the system will appropriately reduce the air outlet temperature to avoid energy waste caused by excessive heating and the problem of excessive indoor temperature.

[0087] After adjusting the window opening and the air outlet temperature of the air conditioner, the fifth air change duration is calculated based on the wind speed of the external wind, the window opening and the target air change volume. The fifth air change duration is compared with the target air change duration set by the user. If the fifth air change duration is shorter than the target air change duration, it means that the current air change speed is too fast, which may cause excessive fluctuations in the indoor temperature, which is not conducive to maintaining a stable indoor environment. At this time, the system will reduce the air outlet speed of the air conditioner so that the air change speed is consistent with the target to maintain the stability of the indoor temperature. If the fifth air change duration is longer than the target air change duration, it means that the air change speed is too slow and cannot meet the needs of indoor air circulation. The system will increase the air outlet speed of the air conditioner and speed up the air change speed to improve the indoor air quality and ensure the freshness and comfort of the indoor air.

[0088] Assuming that when the outside wind temperature at the window is 30℃, which is higher than the maximum value of the perceived temperature range set by the user, 26℃, the system will reduce the window opening from 50% to 30% to reduce the amount of high-temperature wind entering the room, and according to the difference of 4℃ between the outside wind temperature and the maximum value of the perceived temperature range, the air outlet temperature of the air conditioner will be reduced from 24℃ to 22℃ to enhance the cooling effect. The fourth air change duration is calculated to be 33.33 minutes, which is slightly longer than the target air change duration of 30 minutes. Therefore, the system increases the air outlet speed of the air conditioner from 0.3 meters per second to 0.4 meters per second within the perceived wind speed range required by the user to speed up the air change. When the outside wind temperature is 20℃, which is lower than the minimum value of the perceived temperature range of 22℃, the window opening is increased from 50% to 70% to introduce more low-temperature wind, and according to the difference of 2℃ between the outside wind temperature and the minimum value of the perceived temperature range, the air outlet temperature of the air conditioner is increased from 24℃ to 25℃ to avoid over-cooling. The fifth ventilation time is calculated to be 28.57 minutes, which is shorter than the target ventilation time of 30 minutes. Therefore, the system reduces the air outlet speed of the air conditioner from 0.3 meters per second to 0.25 meters per second to keep the indoor temperature stable. Through these adjustments, the window opening and the operating parameters of the air conditioner can be intelligently adjusted according to the temperature changes of the external wind, achieving precise control of the indoor temperature and air circulation to meet the user's comfort needs.

[0089] Preferably, the window opening is first adjusted according to the operation mode, the wind speed and / or temperature of the external wind, and the user's desired temperature range and / or wind speed range, satisfying the relationship:

[0090]

[0091] Where θ represents the window opening, Q target air volume represents the target air volume, A windows represents the total area of ​​windows, V wind speed represents the wind speed of the external wind, H humidity represents the relative humidity of the air, and T 1 Indicates the temperature of the external wind at the current window, T 2 represents the median value of the temperature range required by the user, and ΔT represents the temperature range required by the user.

[0092] The larger the target air exchange volume, the higher the user's demand for indoor air circulation. The system needs to open a larger window area to achieve the required air exchange volume, so the window opening will increase accordingly. Conversely, if the target air exchange volume is smaller, the window opening will also decrease to meet lower ventilation needs. The total area of ​​the window directly determines the maximum possible area of ​​the window opening part. The larger the window area, the smaller the system can open the opening to achieve the required ventilation effect under the same target air exchange volume. Therefore, the window opening will be relatively small. When the window area is small, a larger opening needs to be opened to achieve the same target air exchange volume.

[0093] The speed of the external wind affects the speed and flow of air. The higher the wind speed, the more air passes through the window per unit time. Therefore, under the same target air exchange volume, the window opening can be reduced to achieve the required ventilation effect. On the contrary, if the wind speed is low, the window opening needs to be increased to compensate for the insufficient wind speed and ensure that the target air exchange volume is achieved.

[0094] The relative humidity of the air will affect the density and circulation of the air. When the humidity is high, the air density increases and the ventilation effect is relatively good. Therefore, under the same target air exchange volume, the system can reduce the window opening. When the humidity is low, the air density is small and the ventilation effect is relatively poor. The window opening needs to be increased to meet the ventilation needs. Therefore, the relative humidity of the air will affect the circulation of the air and needs to be taken into consideration during ventilation.

[0095] The median value of the outside air temperature and the user's perceived temperature range (T 2) will affect the adjustment of the window opening. When the difference between the outside wind temperature and the median of the perceived temperature range is large, it means that the natural wind has a greater impact on the indoor temperature. The system will increase the window opening to introduce more natural wind to help adjust the indoor temperature. On the contrary, when the temperature difference is small, the impact of natural wind on the indoor temperature is small, and the window opening will decrease. The difference in the perceived temperature range reflects the user's tolerance for changes in indoor temperature. The larger the difference, the higher the user's tolerance for temperature changes, and there can be greater flexibility in adjusting the window opening to adapt to different ventilation and temperature adjustment needs. When the difference is small, the system needs to adjust the window opening more finely to ensure that the indoor temperature is always within the user's comfort range.

[0096] Assume Q target air exchange volume = 60m 3 / h, A window = 2m 2 , V wind speed = 2m / s, H humidity = 50%, T 1 =28°C, T 2 =24°C, ΔT perceived temperature range = 4°C, the window opening calculated according to the formula is 20%, which means that the area of ​​the open window is 20% of the total window area. The window opening is obtained by comprehensively considering factors such as target air exchange volume, window area, external wind speed, air humidity, the difference between the external wind temperature and the median of the user's perceived temperature range, and the difference in the perceived temperature range. It can accurately control the window opening to meet the user's ventilation needs and comfort requirements, while taking into account the influence of air humidity and temperature on ventilation effects, thereby realizing intelligent adjustment of the indoor environment.

[0097] In another embodiment, in the blowing mode, the second adjustment of the operating parameters of the air conditioner and / or the window opening according to the user's spatial position, the window position, the air conditioner position, the wind direction of the external wind and the operating mode includes:

[0098] A parallel plane is made at the user's location to the wall where the window is located, and when the air conditioner and the window are on different sides of the parallel plane, it is determined whether the wind speed of the external wind at the window is within the range of the user's required wind speed;

[0099] If not, adjust the window opening until the wind speed of the outside wind at the window is within the user's desired perceived wind speed range;

[0100] If so, the air outlet speed of the air conditioner is set to be the same as the wind speed of the external wind at the window, and the air outlet direction of the air conditioner is adjusted to be parallel to the wind direction of the external wind and in the opposite direction.

[0101] By installing a wind speed sensor near the window, the wind speed at the window is monitored in real time, and the monitored wind speed value is compared with the perceived wind speed range set by the user to determine whether the wind speed at the outside wind meets the user's comfort requirements, ensuring that the wind speed felt by the user is within a comfortable range, and avoiding excessive or weak wind speeds that cause discomfort to the user. When the wind speed at the window is not within the perceived wind speed range required by the user, the window opening is dynamically adjusted according to the difference between the wind speed and the perceived wind speed range. If the wind speed is too fast, the window opening is reduced to reduce the wind speed; if the wind speed is too slow, the window opening is increased to increase the wind speed, thereby optimizing the indoor air circulation effect, improving the user's comfort, and creating a suitable wind speed condition for the indoor environment.

[0102] When the outside wind speed at the window is within the user's required body-perceived wind speed range, the air outlet speed of the air conditioner is set to be the same as the outside wind speed at the window. This ensures the consistency of the wind speed between the air conditioner and the outside wind, avoids discomfort to the user due to excessive wind speed differences, improves the comfort of the air conditioner, avoids local overcooling or overheating due to wind speed differences, and enables users to feel comfortable wind speeds everywhere in the room. According to the wind direction of the outside wind at the window, the air outlet direction of the air conditioner is adjusted to be parallel to the outside wind direction, but in the opposite direction. This allows the wind generated by the air conditioner to form convection with the outside wind, promotes the circulation and mixing of indoor air, forms effective air circulation, avoids air stagnation, and ensures the freshness and comfort of indoor air.

[0103] Specifically, by making a parallel plane to the wall where the window is located at the user's position and judging whether the air conditioner and the window are on different sides of the parallel plane, the window opening and the operating parameters of the air conditioner can be intelligently adjusted according to the outside wind speed at the window. When the outside wind speed is not within the user's required somatic wind speed range, the window opening is adjusted to reach a comfortable wind speed; when the outside wind speed is within the somatic wind speed range, the air outlet speed of the air conditioner is matched with the outside wind speed, and the air outlet direction is adjusted to be opposite to the outside wind to form convection, which not only ensures that the wind speed felt by the user is always within a comfortable range, but also optimizes the indoor air circulation effect, improves the air quality, and realizes precise control of the indoor environment, creating a comfortable and healthy living space for users.

[0104] Preferably, in the blowing mode, the second adjustment of the operating parameters of the air conditioner and / or the window opening according to the user's spatial position, the window position, the air conditioner position, the wind direction of the external wind and the operating mode includes:

[0105] Draw a parallel plane to the wall where the window is located at the user's location. When the air conditioner and the window are on different sides of the parallel plane:

[0106] A plane rectangular coordinate system is made with the center point of the opened part of the window as the origin, the horizontal direction as the X axis, and the vertical direction as the Y axis, and the quadrants where the upper right corner, upper left corner, lower left corner and lower right corner of the window are located are set as the first to fourth quadrants respectively;

[0107] Calculate the areas of the wall where the window is located in the first quadrant to the fourth quadrant as the first area to the fourth area respectively;

[0108] According to the first to fourth areas, calculating the area ratios of the remaining three quadrants except the quadrant to which the wind direction of the external wind at the window points;

[0109] The air conditioner blows air to the other three quadrants except the quadrant pointed by the wind direction of the external wind at the window according to the area ratio of the other three quadrants except the quadrant pointed by the wind direction of the external wind at the window, and the blowing speed is set within the range of wind speed perceived by the user required by the user.

[0110] A plane rectangular coordinate system is established at the center point of the open part of the window, with the horizontal direction as the X-axis and the vertical direction as the Y-axis. The upper right corner, upper left corner, lower left corner and lower right corner of the window are located in the first to fourth quadrants respectively. By establishing the coordinate system, the wall where the window is located can be divided into four areas, and each area corresponds to a quadrant. The geometric characteristics of the two-dimensional space are used to simplify the complex three-dimensional space problem into a two-dimensional problem (because the height or length of the four parts is the same), which is convenient for subsequent area calculation and wind direction analysis. Different quadrants represent different spatial areas, and the area and position of these areas will directly affect the distribution of air-conditioning wind and the effect of indoor air flow.

[0111] Measure the dimensions of the wall where the window is located in the first to fourth quadrants respectively, and then calculate the area of ​​each quadrant based on the geometric calculation method. For example, if the shape of the wall where the window is located is a rectangle, the length and width of the wall can be measured, and then the area of ​​each quadrant can be calculated. If the shape of the wall is irregular, it can be divided into multiple small regular shapes (such as rectangles, triangles, etc.), and the area of ​​each small shape can be calculated separately, and then they are added together to get the total area of ​​each quadrant. The calculation of the area allows the air conditioner to reasonably distribute the air volume according to the area distribution of the wall, avoiding excessive blowing in one area and insufficient blowing in another area, thereby improving the comfort and uniformity of the indoor air.

[0112] According to the direction of the external wind at the window, determine the quadrant to which the external wind is directed. For example, if the external wind blows towards the upper right corner of the window, then the quadrant to which the external wind is directed is the first quadrant, and then calculate the area ratio of the remaining three quadrants (second, third, and fourth quadrants) excluding this quadrant. The area ratio can be obtained by dividing the area of ​​each quadrant by the total area. For example, if the area of ​​the second quadrant is 30% of the total area, the area of ​​the third quadrant is 40%, and the area of ​​the fourth quadrant is 30%, then the area ratios of these three quadrants are 30%, 40%, and 30%, respectively. The purpose of calculating the area ratio is to determine the distribution of the blowing intensity of the air conditioner in different quadrants. By understanding the area ratio of each quadrant, the air volume of the air conditioner can be distributed to different quadrants in proportion, thereby achieving optimal control of indoor air flow.

[0113] The air conditioner blows air to the remaining three quadrants except the quadrant pointed by the external wind at the window according to the calculated area ratio. For example, if the area ratios of the second, third and fourth quadrants are 30%, 40% and 30% respectively, the air conditioner will distribute the air volume to these three quadrants according to this ratio. At the same time, the blowing speed is set within the user's required somatic wind speed range to ensure that the user feels a comfortable wind speed. For example, if the user sets the somatic wind speed range to be 0.2 to 0.5 meters per second, the air conditioner will adjust the blowing speed within this range.

[0114] Preferably, in the blowing mode, the second adjustment of the operating parameters of the air conditioner and / or the window opening according to the user's spatial position, the window position, the air conditioner position, the wind direction of the external wind and the operating mode includes:

[0115] A parallel plane is made at the user's location to the wall where the window is located. When the air conditioner and the window are on the same side of the parallel plane, the wind speed of the external wind at the window is compared with the user's desired somatic wind speed range;

[0116] If the wind speed of the external wind at the window is less than the minimum value of the perceived wind speed range required by the user, the window opening is increased until the wind speed of the external wind enters the perceived wind speed range; if the wind speed of the external wind is always lower than the minimum value of the perceived wind speed range, the air conditioner is turned on to accelerate the external wind until the wind speed of the external wind is not lower than the minimum value of the perceived wind speed range;

[0117] If the wind speed of the external wind at the window is greater than the maximum value of the perceived wind speed range required by the user, the window opening is reduced until the wind speed of the external wind enters the perceived wind speed range.

[0118] When the wind speed at the window is less than the minimum value of the perceived wind speed range required by the user, it means that the current ventilation volume is insufficient and cannot meet the user's comfort requirements. The window opening is automatically increased to increase the area of ​​the vents, thereby increasing the wind speed of the outside wind entering the room. After increasing the window opening, more air can enter the room through the window, and the wind speed will increase accordingly until it reaches or exceeds the minimum value of the perceived wind speed range.

[0119] If the outside wind speed at the window is always lower than the minimum value of the user's required somatic wind speed range, even if the window opening has been increased to the maximum, it still cannot meet the user's comfort requirements. At this time, the system will start the auxiliary function of the air conditioner, using the air conditioner's fan or air supply system to accelerate the outside wind until the wind speed is no lower than the minimum value of the somatic wind speed range. The air conditioner increases its own air outlet speed, mixes the outside wind with the conditioned wind, and forms a stronger airflow, thereby increasing the overall wind speed. The purpose of this step is to ensure that the indoor wind speed reaches the user's comfort standard through the auxiliary role of the air conditioner when the window opening cannot meet the demand. The intervention of the air conditioner can make up for the lack of natural wind and provide additional air volume support, so that the user is always in a comfortable wind speed environment.

[0120] When the wind speed at the window is greater than the maximum value of the perceived wind speed range required by the user, it means that the current ventilation volume is too large and may make the user feel uncomfortable. At this time, the window opening is automatically reduced to reduce the area of ​​the vents, thereby reducing the wind speed of the outside wind entering the room. After reducing the window opening, the amount of air entering the room is reduced, and the wind speed will be reduced accordingly until it drops below the maximum value of the perceived wind speed range.

[0121] Preferably, the spatial position of the user includes the distance between the user and the window;

[0122] When the wind speed of the external wind is within the perceived wind speed range and the temperature of the external wind is outside the perceived temperature range, comparing the distance between the user and the window with the adjustable distance;

[0123] If the distance between the user and the window is greater than the adjustable distance, the air outlet temperature of the air conditioner is adjusted according to the body temperature range according to the minimum difference between the temperature of the outside wind and the edge value of the body temperature range;

[0124] If the distance between the user and the window is less than the adjustable distance, the window is closed, and the air outlet speed and air outlet temperature of the air conditioner are adjusted according to the perceived wind speed range and the perceived temperature range.

[0125] Through positioning technology (such as Wi-Fi positioning, Bluetooth positioning, etc.) or sensors (such as infrared sensors, ultrasonic sensors, etc.), the system can monitor and determine the specific location of the user in the room in real time, and then calculate the distance between the user and the window. The adjustable distance is used to determine whether the user is in a state where the air conditioner and the window need to be adjusted. The adjustable distance can be set according to factors such as the size of the room, the location of the window, the distance between the air conditioner and the window, and the user's comfort requirements. When the distance between the user and the window is within the adjustable distance, the air conditioner does not adjust the external wind sufficiently or too late to adjust, and the user's experience will plummet. The air conditioning's regulated air and the external wind need to be fully mixed at the adjustable distance. When the distance between the user and the window is greater than the adjustable distance, and the wind speed of the external wind is within the range of the perceived wind speed but the temperature is outside the range of the perceived temperature, the air outlet temperature of the air conditioner is adjusted according to the minimum difference between the temperature of the external wind and the edge value of the perceived temperature range. Specifically, if the temperature of the outside wind is higher than the maximum value of the somatic temperature range, the system will lower the air outlet temperature of the air conditioner to offset the high temperature effect brought by the outside wind; if the temperature of the outside wind is lower than the minimum value of the somatic temperature range, the system will increase the air outlet temperature of the air conditioner to compensate for the low temperature effect brought by the outside wind. The air conditioner is used to compensate for the impact of the outside wind on the indoor temperature, so that the indoor temperature is kept within the user's comfortable range. This can prevent users from feeling uncomfortable due to the outside wind temperature being too high or too low, while reducing the frequency and amplitude of window adjustment to improve the energy efficiency of the system.

[0126] When the distance between the user and the window is less than the adjustable distance, and the wind speed of the outside wind is within the perceived wind speed range but the temperature is outside the perceived temperature range, the air conditioner's adjustment response is too late, and the system will close the window to reduce the direct impact of the outside wind on the user experience. At the same time, the air conditioner will be used as the main air outlet target, and the air outlet speed and air outlet temperature of the air conditioner will be adjusted according to the perceived wind speed range and the perceived temperature range.
