Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner and window linkage control, in particular to an air conditioner and intelligent window linkage control method and system. BACKGROUND

[0002] In modern buildings and home environments, the linkage control of air conditioners and windows faces many challenges. Traditional operation methods require 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 conditioner efficiency, and even cause damage to the equipment due to forgetting to close the windows. Although some products have implemented simple linkage functions, such as automatically closing the windows when the air conditioner is turned on, this basic linkage cannot intelligently adjust according to real-time changes in indoor and outdoor environments, has a single function, and cannot meet users' higher requirements for comfort and energy saving. Long-term use of air conditioners can cause indoor air to be dry and not well ventilated, affecting health and comfort, and traditional window ventilation methods cannot effectively cooperate with air conditioners, resulting in large indoor temperature fluctuations and poor user experience. In addition, existing linkage systems have limited energy-saving measures and cannot intelligently control energy saving according to changes in indoor and outdoor environments and user habits, resulting in serious energy waste and increasing the economic and environmental burden on users. SUMMARY

[0003] To overcome the above-mentioned defects, the present application provides an air conditioner and intelligent window linkage control method and system, aiming to solve the problems of inconvenient operation and insufficient comfort adjustment in traditional technology, combining air conditioners with the environment to increase user comfort and reduce air conditioner energy consumption.

[0017] Further, when the temperature of the external wind is outside the user-required range of the thermal sensation temperature, if the temperature of the external wind is greater than the maximum value of the user-required range of the thermal sensation temperature, the window opening degree is decreased when the wind speed of the external wind is within the user-required range of the thermal sensation wind speed;

[0027] If the air conditioner and the window are on different sides of the parallel plane of the wall surface on which the window is located, it is determined whether the wind speed of the external wind at the window is in the user required sensible wind speed range;

[0028] If not, the window opening is adjusted until the wind speed of the external wind at the window is in the user required sensible wind speed range;

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

[0030] Preferably, in the blowing mode, the second adjustment of the operation 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 operation mode includes:

[0031] If the air conditioner and the window are on different sides of the parallel plane of the wall surface on which the window is located:

[0032] A Cartesian coordinate system is established 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 in which the right upper corner, the left upper corner, the left lower corner, and the right lower corner of the window are located are respectively set as the first to fourth quadrants;

[0055] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0056] In the present application, the term "comprising" or "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitation, the element defined by the sentence "including a" does not exclude the presence of other identical elements in the process, method, article or equipment including the element.

[0057] The present application provides an air conditioner and intelligent window linkage control method, as shown in Figure 1 A preferred embodiment of the present application, the linkage control method comprises the following steps:

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

[0059] In the present embodiment, the control system or the system is provided with the air conditioner and intelligent window linkage control method proposed by the present application, which can be arranged in the air conditioner or an external controller, and can control the opening and closing of the window, the adjustment of the air conditioner operating parameters and the acquisition of the parameters through the control signal.

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

[0061] S2: Continuously acquire the spatial position of the user, input the demand information and the spatial position to the air conditioner, and the demand information includes the user's required range of thermal sensation temperature, range of thermal sensation wind speed, operation mode of the air conditioner, and operation parameters;

[0062] Using indoor positioning technologies such as Wi-Fi positioning, Bluetooth positioning, or ultrasonic positioning, the user's specific location in the room is calculated through communication between the user's smart phone, wearable device, or special positioning tag and the indoor positioning base station or signal source. At the same time, through the user interface (such as a mobile phone APP, voice assistant, or remote control, etc.), the user can input their own demand information, including the range of thermal sensation temperature, the range of thermal sensation wind speed, the operation mode of the air conditioner (such as cooling, heating, dehumidifying, automatic, etc.), and specific operation parameters (such as temperature setting, wind speed setting, wind direction setting, etc.). The user interface converts these demand information into data signals and transmits them to the control system of the air conditioner, which provides user demand basis for subsequent air conditioner and window linkage control according to the user's spatial position and demand information.

[0063] S3: First adjustment of the window opening degree according to the operation mode, wind speed and / or temperature of the external wind, and the user's required range of thermal sensation temperature and / or range of thermal sensation wind speed;

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

[0065] S4: second adjusting the operation parameters of the air conditioner and / or the opening degree of the window according to the spatial position of the user, the position of the window, the position of the air conditioner, the wind direction of the external wind, and the operation mode of the air conditioner;

[0066] The operation parameters of the air conditioner include the air outlet temperature, the air outlet direction, and the air outlet speed of the air conditioner.

[0067] The control system comprehensively considers the spatial position of the user, the position of the window, the position of the air conditioner, the wind direction of the external wind, and the operation mode of the air conditioner, and further finely adjusts the air outlet temperature, the air outlet direction, and the air outlet speed of the air conditioner, and the opening degree of the window. 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 adjusts the air outlet direction of the air conditioner to avoid blowing directly on the user, and adjusts the air outlet temperature of the air conditioner according to the required thermal sensation temperature range of the user to compensate for the influence of the external wind on the indoor temperature. If the user is far away from the window, the system increases 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 dynamically adjusts the opening degree of the window according to the wind direction and speed of the external wind to achieve the best ventilation effect and indoor comfort. Through such comprehensive adjustment, the user can obtain an ideal thermal sensation experience in different positions and 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. The ventilation mode is a mode of exchanging indoor air with outdoor air when the indoor air is relatively turbid. Different from the ordinary air conditioner ventilation mode, the ventilation mode proposed in the present application increases the ventilation by opening the window, which can quickly exhaust the turbid gas or harmful gas in the room. The existing air conditioner not only has the functions of refrigeration and heating, but also has the function of blowing like a fan. If only relying on the blowing of the air conditioner will increase the power consumption of the air conditioner. Assuming that the outdoor air flow rate is fast (such as in autumn), the air inlet of the window can assist the blowing of the air conditioner or the air inlet of the air conditioner can assist the air inlet of the window to realize blowing for the user, which can save the energy consumption of the air conditioner. In addition, the operation parameters of the air conditioner can be changed. When the outdoor air inlet (wind direction, wind speed, or temperature, etc.) cannot be changed in a short time, adjusting the opening degree of the window and the operation parameters of the air conditioner can make the user maintain a stable and comfortable experience.

[0069] Preferably, in the ventilation mode, the demand information further includes a target ventilation amount and a target ventilation time length.

[0070] The first adjusting the opening degree of the window according to the operation mode, the wind speed and / or temperature of the external wind, the required thermal sensation temperature range and / or thermal sensation wind speed range of the user includes:

[0071] When the temperature of the outside wind is within the range of the user's required body temperature, a first air exchange time is obtained according to the current wind speed of the outside wind, the window opening degree and the target air exchange amount;

[0072] The target air exchange time is compared with the first air exchange time. If the first air exchange time is less than the target air exchange time, the window opening degree is increased and the wind speed of the outside wind is continuously monitored. A second air exchange time after the change of the window opening degree is calculated until the wind speed of the outside wind at the window is equal to the maximum value of the range of the user's required body wind speed or the second air exchange time is equal to the target air exchange time.

[0073] If the first air exchange time is greater than the target air exchange time, the window opening degree is reduced and the wind speed of the outside wind is continuously monitored. A third air exchange time after the change of the window opening degree is calculated until the wind speed of the outside wind at the window is equal to the minimum value of the range of the user's required body wind speed or the third air exchange time is equal to the target air exchange time.

[0074] In the air exchange mode, the user's set requirement information is first obtained, including the target air exchange amount and the target air exchange time. The user specifies the required indoor air amount (target air exchange amount) in a unit time and the time required to complete the air exchange (target air exchange time) through an 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 requirements, ensure that the indoor air quality meets the user's expected standard, and provide an important reference for subsequent window opening degree adjustment.

[0075] According to the running mode (air exchange mode) of the air conditioner, the wind speed and temperature of the outside wind at the window, and the range of the user's required body temperature and body wind speed, the window opening degree is first adjusted. When the temperature of the outside wind is within the range of the user's set body temperature, a first air exchange time is obtained according to the current wind speed of the outside wind, the window opening degree and the target air exchange amount. The calculation method of the first air exchange time can be to divide the target air exchange amount by the product of the effective area of the opened part of the window and the wind speed of the outside wind. Specifically, the target air exchange amount refers to the required indoor air amount in the user's set time, the effective area of the opened part of the window refers to the actual opened area of the window, and the wind speed of the outside wind refers to the speed of the natural wind at the window. Through this calculation method, the time required to reach the target air exchange amount under the current window opening degree and wind speed of the outside wind can be obtained. If the calculated air exchange time is less than the user's set target air exchange time, it indicates that the current window opening degree and wind speed of the outside wind cannot meet the user's air exchange requirement, and the window opening degree needs to be increased. Conversely, if the calculated air exchange time is greater than the target air exchange time, the window opening degree needs to be reduced to ensure that the actual air exchange time is consistent with the user's set target and the wind speed of the outside wind at the window is within the user's comfortable range.

[0076] Assuming the target air exchange volume is 60 cubic meters per hour, the total area of the window is 2 square meters, the speed of the incoming wind is 2 meters per second, the opening degree of the window is 50%, the user's required range of the sensible temperature is 22 to 26 degrees Celsius, the range of the sensible wind speed is 0.2 to 0.5 meters per second, and the target air exchange duration is set to 30 minutes. First, the first air exchange duration is calculated according to the current speed of the incoming wind, the opening degree of the window, and the target air exchange volume. The target air exchange volume is divided by the product of the effective area of the opened part of the window (the total area of the window multiplied by the opening degree coefficient) and the speed of the incoming wind, resulting in a first air exchange duration of 60 minutes. Then the target air exchange duration is compared with the first air exchange duration, and it is found that the first air exchange duration is greater than the target air exchange duration (60 minutes > 30 minutes), indicating that the current opening degree of the window is too large, resulting in too fast air exchange. Therefore, the opening degree of the window needs to be reduced. Assuming that the opening degree of the window is reduced to 30%, the third air exchange duration is recalculated, resulting in 50 minutes. The opening degree of the window continues to be adjusted until the third air exchange duration equals the target air exchange duration (30 minutes), while ensuring that the speed of the incoming wind at the window is not lower than the minimum value of the user's required range of the sensible wind speed (0.2 meters per second), finally meeting the user's requirements for indoor air quality and comfort.

[0077] Preferably, when the temperature of the incoming wind is outside the user's required range of the sensible temperature, if the temperature of the incoming wind is greater than the maximum value of the user's required range of the sensible temperature, the opening degree of the window is reduced when the speed of the incoming wind is within the user's required range of the sensible wind speed;

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

[0079] According to the difference between the fourth air exchange duration and the target air exchange duration, the outlet speed of the air conditioner is increased or decreased within the user's required range of the sensible wind speed;

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

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

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

[0083] When the temperature of the external wind at the window exceeds the maximum value of the user's set thermal comfort temperature range, it means that the temperature of the natural wind is high, and if a large amount of it enters the indoor environment, it will cause the indoor temperature to rise, making the user feel overheated. At this time, by reducing the window opening degree, the amount of high-temperature external wind entering the indoor environment can be effectively reduced, thereby slowing down the rising speed of the indoor temperature. The reduction of the window opening degree will reduce the area of the opened part of the window, and thus reduce the air flow, so that the influence of the high-temperature wind on the indoor environment is weakened.

[0084] After reducing the window opening degree, the air conditioner's outlet air temperature is adjusted according to the difference between the temperature of the external wind and the maximum value of the user's thermal comfort temperature range. If the temperature of the external wind is much higher than the maximum value of the user's thermal comfort temperature range, it means that the indoor temperature may rise rapidly, and the air conditioner needs to provide stronger cooling effect to offset the influence of the high-temperature wind, so the outlet air temperature of the air conditioner needs to be reduced to speed up the reduction of the indoor temperature. On the contrary, if the temperature of the external wind is only slightly higher than the maximum value of the user's thermal comfort temperature range, it means that the indoor temperature rises slowly, and the air conditioner only needs to cool moderately, so the system will appropriately increase the outlet air temperature to avoid the problems of energy waste and excessively low indoor temperature caused by excessive cooling.

[0085] After adjusting the window opening degree and the air conditioner's outlet air temperature, the fourth air exchange time is calculated according to the wind speed of the external wind, the window opening degree and the target air exchange volume at this time. The fourth air exchange time is compared with the target air exchange time set by the user. If the fourth air exchange time is shorter than the target air exchange time, it means that the current air exchange speed is too fast, which may cause the indoor temperature to fluctuate too much and is not conducive to maintaining a stable indoor environment. At this time, the outlet air speed of the air conditioner is reduced to make the air exchange speed consistent with the target, so as to maintain the stability of the indoor temperature. If the fourth air exchange time is longer than the target air exchange time, it means that the air exchange speed is too slow and cannot meet the demand of indoor air circulation, so the system will increase the outlet air speed of the air conditioner to speed up the air exchange speed, so as to improve the indoor air quality and ensure the freshness and comfort of the indoor air. When the temperature of the external wind at the window is lower than the minimum value of the user's set thermal comfort temperature range, it means that the temperature of the natural wind is low, and if a large amount of it enters the indoor environment, it will cause the indoor temperature to drop, making the user feel too cold. At this time, by increasing the window opening degree, more low-temperature external wind can be introduced, thereby reducing the indoor temperature and making the indoor temperature approach the lower limit of the user's comfort temperature range. The increase of the window opening degree will increase the area of the opened part of the window, and thus increase the air flow, so that the low-temperature wind can more effectively enter the indoor environment and help to reduce the indoor temperature.

[0086] After increasing the window opening, the air conditioner's outlet temperature is adjusted according to the difference between the outside wind temperature and the minimum value of the user's thermal comfort temperature range. If the outside wind temperature is much lower than the minimum value of the user's thermal comfort temperature range, it indicates that the indoor temperature may drop rapidly, and the air conditioner needs to provide stronger heating effect to offset the influence of low-temperature wind, so the outlet temperature of the air conditioner is increased to speed up the indoor temperature rise. On the contrary, if the outside wind temperature is only slightly lower than the minimum value of the user's thermal comfort temperature range, it indicates that the indoor temperature drops slowly, and the air conditioner only needs moderate heating, so the system appropriately reduces the outlet temperature to avoid excessive heating and the problem of high indoor temperature caused by energy waste.

[0087] After adjusting the window opening and the air conditioner's outlet temperature, the fifth air exchange time is calculated according to the wind speed of the outside wind, the window opening, and the target air exchange volume. Comparing the fifth air exchange time with the target air exchange time, if the fifth air exchange time is shorter than the target air exchange time, it indicates that the current air exchange speed is too fast, which may cause large indoor temperature fluctuations and is not conducive to maintaining a stable indoor environment. At this time, the system reduces the air conditioner's outlet speed to make the air exchange speed consistent with the target, so as to maintain the stability of the indoor temperature. If the fifth air exchange time is longer than the target air exchange time, it indicates that the air exchange speed is too slow and cannot meet the demand for indoor air circulation, so the system increases the air conditioner's outlet speed to speed up the air exchange speed, improve indoor air quality, and ensure the freshness and comfort of indoor air.

[0088] Assuming that when the outside wind temperature at the window is 30℃, which is higher than the maximum value of the user's thermal comfort temperature range 26℃, the system reduces the window opening from 50% to 30% to reduce the amount of high-temperature wind entering the room, and according to the difference between the outside wind temperature and the maximum value of the thermal comfort temperature range 4℃, the outlet temperature of the air conditioner is reduced from 24℃ to 22℃ to strengthen the cooling effect. The fourth air exchange time is calculated to be 33.33 minutes, which is slightly longer than the target air exchange time of 30 minutes, so the system increases the air conditioner's outlet speed from 0.3 meters per second to 0.4 meters per second within the user's required thermal wind speed range to speed up the air exchange speed. When the outside wind temperature is 20℃, which is lower than the minimum value of the thermal comfort temperature range 22℃, the window opening is increased from 50% to 70% to introduce more low-temperature wind, and according to the difference between the outside wind temperature and the minimum value of the thermal comfort temperature range 2℃, the outlet temperature of the air conditioner is increased from 24℃ to 25℃ to avoid excessive cooling. The fifth air exchange time is calculated to be 28.57 minutes, which is shorter than the target air exchange time of 30 minutes, so the system reduces the air conditioner's outlet speed from 0.3 meters per second to 0.25 meters per second to maintain the stability of the indoor temperature. Through these adjustments, the system can intelligently adjust the window opening and the operating parameters of the air conditioner according to the temperature changes of the outside wind, accurately control the indoor temperature and air circulation, and meet the user's comfort requirements.

[0089] Preferably, the first adjustment of the window opening degree is made according to the operating mode, the wind speed and / or temperature of the external wind, the required range of the user's sensible temperature and / or the range of the user's sensible wind speed, and the relationship is satisfied:

[0090]

[0091] wherein θ represents the window opening degree, Qtarget air exchange volume represents the target air exchange volume, Awindow represents the total area of the window, Vwind speed represents the wind speed of the external wind, Hhumidity represents the relative humidity of the air, T1 represents the temperature of the external wind at the current window, T2 represents the median value of the required range of the user's sensible temperature, and ΔT sensible temperature range represents the required range of the user's sensible temperature.

[0092] The greater the target air exchange volume, the higher the user's demand for indoor air circulation, and the system needs to open a larger window area to achieve the required air exchange volume, so the window opening degree is increased accordingly, and vice versa. The target air exchange volume is smaller, and the window opening degree is also reduced to meet the lower ventilation demand; the total area of the window directly determines the maximum possible area of the window opening part, and the larger the window area, the smaller the opening degree that can be opened by the system to achieve the required ventilation effect under the same target air exchange volume, so the window opening degree is relatively small, and in the case of a smaller window area, a larger opening degree is needed to achieve the same target air exchange volume.

[0093] The wind speed of the external wind affects the speed and flow of air flow, and the greater the wind speed, the more air passes through the window per unit time, so under the same target air exchange volume, the window opening degree can be reduced to achieve the required ventilation effect. Conversely, the wind speed is small, and the window opening degree needs to be increased to compensate for the insufficient wind speed to ensure that the target air exchange volume is reached.

[0094] The relative humidity of the air affects the density and flow of the air, and when the humidity is high, the air density increases, and the ventilation effect is relatively good, so under the same target air exchange volume, the system can reduce the window opening degree. When the humidity is low, the air density is small, and the ventilation effect is relatively poor, and the window opening degree needs to be increased to meet the ventilation demand, so the relative humidity of the air will affect the flow of the air, and needs to be considered when ventilating.

[0095] The difference between the outside wind temperature and the median of the user's sensible temperature range (T2) affects the adjustment of the window opening. When the difference between the outside wind temperature and the median of the sensible temperature range is large, it means that the natural wind has a greater impact on the indoor temperature, and the system will increase the window opening to introduce more natural wind to help regulate the indoor temperature. Conversely, when the temperature difference is small, the impact of natural wind on indoor temperature is small, and the window opening will be reduced. The difference in the sensible temperature range reflects the user's tolerance to indoor temperature changes. The larger the difference, the higher the user's tolerance to temperature changes, and there is more flexibility in adjusting the window opening to meet different ventilation and temperature regulation needs. A smaller difference requires more precise adjustment of the window opening to ensure that the indoor temperature is always within the user's comfort range.

[0096] Assuming Qtarget air exchange volume = 60 m 3 / h, Awindow = 2 m 2 , Vwind speed = 2 m / s, Hhumidity = 50%, T1 = 28°C, T2 = 24°C, ΔT sensible temperature range = 4°C, the window opening calculated according to the formula is 20%, which means that the area of the window opening is 20% of the total area of the window. The window opening is obtained by considering the target air exchange volume, window area, outside wind speed, air humidity, difference between outside wind temperature and median of user's sensible temperature range, and difference in sensible temperature range, etc. It can accurately control the opening of the window to meet the user's air exchange needs and comfort requirements, while taking into account the influence of air humidity and temperature on ventilation effect, and realize intelligent adjustment of indoor environment.

[0097] In another embodiment, in the blowing mode, the second adjustment of the operation 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 outside wind and the operation mode includes:

[0098] Parallel to the wall surface on which the window is located at the user's position, when the air conditioner and the window are on different sides of the parallel plane, it is determined whether the wind speed of the outside wind at the window is within the user's required sensible wind speed range;

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

[0100] If yes, set the air outlet speed of the air conditioner to be the same as the wind speed of the outside wind at the window, and adjust the air outlet direction of the air conditioner to be parallel to the wind direction of the outside wind, with opposite directions.

[0101] By installing a wind speed sensor near the window, the external wind speed at the window is monitored in real time, and the monitored wind speed value is compared with the user-set range of wind speed for body feeling to determine whether the external wind speed meets the user's comfort requirement, ensuring that the user feels the wind speed within the comfortable range and avoiding too strong or too weak wind speed from causing discomfort to the user. When the external wind speed at the window is not within the user-required range of wind speed for body feeling, the opening degree of the window is dynamically adjusted according to the difference between the wind speed and the range of wind speed for body feeling. If the wind speed is too fast, the opening degree of the window is reduced to lower the wind speed; if the wind speed is too slow, the opening degree of the window is increased to increase the wind speed, thereby optimizing the indoor air circulation effect and improving the user's comfort, and creating a suitable wind speed condition for the indoor environment.

[0102] When the external wind speed at the window is within the user-required range of wind speed for body feeling, the air outlet speed of the air conditioner is set to be the same as the external wind speed at the window, which can ensure the consistency of the wind speed between the air generated by the air conditioner and the external wind, avoid discomfort caused by too large wind speed difference, improve the comfort of the air conditioner, and avoid local overcooling or overheating caused by wind speed difference, so that the user can feel comfortable wind speed everywhere in the room. According to the wind direction of the external wind at the window, the air outlet direction of the air conditioner is adjusted to be parallel to the wind direction of the external wind but opposite in direction, which can utilize the convection formed by the air generated by the air conditioner and the external wind to promote the circulation and mixing of indoor air, form effective air circulation, avoid air stagnation, and ensure the freshness and comfort of indoor air.

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

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

[0105] Making a parallel plane of the wall surface 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 Cartesian coordinate system is established 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. 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.

[0107] The areas of the first to fourth quadrants of the wall where the window is located are calculated as the first to fourth areas, respectively.

[0108] According to the first to fourth areas, the area proportions of the remaining three quadrants except the one pointed by the wind direction of the external wind at the window are calculated.

[0109] The air conditioner blows air to the remaining three quadrants except the one pointed by the wind direction of the external wind at the window according to the area proportions of the remaining three quadrants, and the blowing speed is set within the required body feeling wind speed range of the user.

[0110] A Cartesian coordinate system is established at the center point of the opened 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. Through the establishment of the coordinate system, the wall where the window is located can be divided into four areas, each corresponding to a quadrant. The two-dimensional geometric properties 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 facilitates 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 conditioner air and the effect of indoor air flow.

[0111] The dimensions of the first to fourth quadrants of the wall where the window is located are measured, and then the areas of the quadrants are calculated according to geometric calculation methods. For example, if the shape of the wall where the window is located is rectangular, 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 is calculated, and then the total area of each quadrant is obtained by adding them up. The calculation of the area enables 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 indoor air.

[0112] According to the direction of the external wind at the window, the quadrant pointed by the external wind is determined. For example, if the external wind blows to the right upper corner of the window, the quadrant pointed by the external wind is the first quadrant, and then the area proportions of the remaining three quadrants (the second, third and fourth quadrants) except the quadrant are calculated. The area proportions 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% of the total area, and the area of the fourth quadrant is 30% of the total area, the area proportions of the three quadrants are 30%, 40% and 30% respectively. The purpose of calculating the area proportions is to determine the air blowing intensity distribution of the air conditioner in different quadrants. By knowing the area proportions of the quadrants, the air volume of the air conditioner can be distributed to different quadrants in proportion, so as to realize the optimized control of indoor air flow.

[0113] According to the calculated area proportions, the air conditioner blows air to the remaining three quadrants except the quadrant pointed by the external wind at the window. For example, if the area proportions of the second, third and fourth quadrants are 30%, 40% and 30% respectively, the air conditioner will distribute the air volume to the three quadrants in proportion, and at the same time, the blowing speed is set in the range of the user required felt wind speed to ensure that the user feels comfortable wind speed. For example, if the range of the user required felt wind speed is 0.2 to 0.5 meters per second, the air conditioner will adjust the blowing speed to be within this range.

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

[0115] When the air conditioner and the window are on the same side of the parallel plane of the wall surface at the position of the user, the wind speed of the external wind at the window is compared with the range of the user required felt wind speed;

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

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

[0118] When the wind speed of the external wind at the window is less than the minimum value of the range of the user's required wind speed, it indicates that the current ventilation is insufficient to meet the user's comfort requirement, and the opening of the window is automatically increased to increase the area of the ventilation opening, so as to increase the wind speed of the external wind into the room. After increasing the opening of the window, more air can enter the room through the window, and the wind speed will be increased accordingly until it reaches or exceeds the minimum value of the range of the wind speed.

[0119] If the wind speed of the external wind at the window is always lower than the minimum value of the range of the user's required wind speed, even if the opening of the window has been increased to the maximum, it still cannot meet the user's comfort requirement. At this time, the system will start the auxiliary function of the air conditioner, and use the fan or air supply system of the air conditioner to accelerate the external wind until the wind speed is not lower than the minimum value of the range of the wind speed. The air conditioner mixes the external wind with the air conditioner wind by increasing the air outlet speed of the air conditioner, to form a stronger airflow, so as to increase 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 action of the air conditioner when the opening of the window cannot meet the requirement. The intervention of the air conditioner can make up for the deficiency of natural wind and provide additional wind support, so that the user is always in a comfortable wind speed environment.

[0120] When the wind speed of the external wind at the window is greater than the maximum value of the range of the user's required wind speed, it indicates that the current ventilation is too large, which may make the user feel uncomfortable. At this time, the opening of the window is automatically reduced to reduce the area of the ventilation opening, so as to reduce the wind speed of the external wind into the room. After reducing the opening of the window, the amount of air entering the room is reduced, and the wind speed will be reduced accordingly until it is below the maximum value of the range of the wind speed.

[0121] Preferably, the spatial position of the user includes the distance of the user from the window.

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

[0123] If the distance of the user from the window is greater than the adjustable distance, 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 range of the temperature, according to the range of the temperature.

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

[0125] By 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 that requires adjustment of the air conditioner and the window. The adjustable distance can be set according to the size of the room, the position of the window, the distance between the air conditioner and the window, and the user's comfort requirements, etc. When the distance between the user and the window is within the adjustable distance, the air conditioner's adjustment of the outside air is insufficient or not in time, and the user's experience will decrease linearly. The air conditioner's outflow and outside air need to be fully mixed within the adjustable distance. When the distance between the user and the window is greater than the adjustable distance, and the wind speed of the outside air is within the range of the body temperature, but the temperature is outside the range of the body temperature, the air conditioner's outflow temperature is adjusted according to the minimum difference between the temperature of the outside air and the edge value of the body temperature range. Specifically, if the temperature of the outside air is higher than the maximum value of the body temperature range, the system will lower the air conditioner's outflow temperature to offset the high temperature effect of the outside air; if the temperature of the outside air is lower than the minimum value of the body temperature range, the system will increase the air conditioner's outflow temperature to compensate for the low temperature effect of the outside air. By adjusting the air conditioner to compensate for the influence of the outside air on the indoor temperature, the indoor temperature can be kept within the user's comfort range, which can avoid the user's discomfort caused by the high or low temperature of the outside air, and reduce the frequency and amplitude of window adjustment, improving 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 air is within the range of the body temperature, but the temperature is outside the range of the body temperature, the air conditioner's adjustment reaction has already been too late, and the system will close the window to reduce the direct impact of the outside air on the user's experience. At the same time, the air conditioner is the main air outlet target, and the air conditioner's outflow wind speed and outflow temperature are adjusted according to the range of the body temperature and the range of the body temperature.

[0127] An air conditioner and intelligent window linkage control system, the linkage control system applies the linkage control method as described above, such as Figure 2 As shown, the linkage control system comprises:

[0128] An environmental detection module 1 for continuously acquiring the wind direction, wind speed and temperature of the outside air at the window;

[0129] A demand input module 2 for continuously acquiring the spatial position of the user, inputting demand information and the spatial position to the air conditioner, the demand information including the user's required body temperature range, body wind speed range, air conditioner's operation mode and operation parameters;

[0130] The first adjusting module 3 is configured to perform first adjustment on the window opening degree according to the operation mode, the wind speed and / or temperature of the external wind, and the required range of the body temperature and / or the range of the body wind speed of the user.

[0131] The second adjusting module 4 is configured to perform second adjustment on the operation parameters of the air conditioner and / or the window opening degree according to the spatial position of the user, the position of the window, the position of the air conditioner, the wind direction of the external wind, and the operation mode.

[0132] The operation parameters of the air conditioner include the air outlet temperature, the air outlet direction, and the air outlet speed of the air conditioner.
