Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more specifically, to an air conditioner and its control method. Background Art

[0002] With the continuous development of smart home technology, air conditioners, as important devices in home life, are becoming increasingly intelligent. Current air conditioner products on the market are suitable for different-sized spaces according to different cooling and heating capacities (i.e., "horsepower"). However, even for the same horsepower, the maximum efficiency range of air conditioners is relatively wide. For example, a 35-type air conditioner (i.e., a 1.5-horsepower air conditioner) is suitable for rooms ranging from 16 square meters to 24 square meters. This means that for a smaller room, such as 16 square meters, the air conditioner may cause overcooling or overheating; while for a larger room, such as 24 square meters, the desired temperature adjustment effect may not be achieved. This difference is not only affected by the actual size of the room but is also closely related to factors such as changes in the number of people in the room and the height of the room. Therefore, it is imperative to design an air conditioner that can automatically adjust its capacity according to the actual situation of the room and relevant parameter inputs.

[0003] With the diversification of modern architectural designs, large floor-to-ceiling windows are widely used in residential and office spaces, increasing indoor lighting and views. However, this design also poses challenges in controlling the indoor-outdoor temperature difference, especially under extreme climate conditions. Traditional air conditioning systems are difficult to precisely handle the complex heat exchange situations caused by large floor-to-ceiling windows, resulting in low energy efficiency and indoor temperature fluctuations. Therefore, there is a need for an air conditioning system that can intelligently adjust and precisely control the indoor temperature. Summary of the Invention

[0004] The first object of the present invention is to provide a control method for an air conditioner that can achieve precise temperature control and effectively reduce energy consumption.

[0005] The second object of the present invention is to provide an air conditioner that implements the above control method.

[0006] To achieve the above first object, the present invention provides a control method for an air conditioner, including an adaptive mode and a parameter dynamic adjustment mode; after entering the adaptive mode, according to the basic parameters of the room, calculate the first operating frequency of the compressor required to reach the first set temperature within the first preset time period; after entering the parameter dynamic adjustment mode, control the compressor to operate at the first operating frequency for the second preset time period, then obtain the current indoor environmental temperature and determine whether the difference between the current indoor environmental temperature and the theoretical indoor environmental temperature at this moment is greater than the preset temperature difference; if the difference between the current indoor environmental temperature and the theoretical indoor environmental temperature at this moment is greater than the preset temperature difference, automatically correct the basic parameters of the room.

[0007] As can be seen from the above solution, the air conditioner of the present invention has an adaptive mode and a parameter dynamic adjustment mode. In the adaptive mode, the air conditioner can calculate the heat exchange amount required to reach the first set temperature within the first preset time period based on the basic parameters of the room input by the client, and then determine the operating frequency of the compressor, which is a theoretical value. After entering the parameter dynamic adjustment mode, after the compressor operates at the first operating frequency obtained in the adaptive mode for the second preset time period, it is judged whether the current indoor environmental temperature can reach the theoretical indoor environmental temperature at this moment, that is, if the second preset time period is equal to the first preset time period, it is seen whether the current indoor environmental temperature can reach the set value. If the current indoor environmental temperature cannot reach the theoretical indoor environmental temperature at this moment, the basic parameters of the room are automatically corrected. That is, the parameter dynamic adjustment mode only considers the influence of parameters such as walls on the heat exchange performance, and does not consider the influence of the heat radiation of floor-to-ceiling windows on the heat exchange performance, so as to realize the correction of the basic parameters of the room according to the heat exchange situation.

[0008] Thus, the operating frequency of the air conditioner can be matched with the basic parameters of the room, avoiding the situations in the prior art where a smaller room may cause overcooling or overheating and a larger room may not achieve the ideal temperature adjustment effect. Therefore, the intelligent air conditioner of the present invention can not only provide a more stable indoor temperature, but also effectively reduce energy consumption. Moreover, the air conditioner adaptive mode can more closely meet different application scenarios within the actual capacity of the air conditioner. Through continuous monitoring and intelligent feedback mechanisms, the system can not only ensure comfort, but also conform to the current society's advocacy of a green and low-carbon lifestyle.

[0009] A preferred solution is that the air conditioner also has an automatic adjustment mode; after entering the automatic adjustment mode, according to the basic parameters of the room corrected in the parameter dynamic adjustment mode, calculate the second operating frequency of the compressor required to reach the set temperature within the third preset time period; after the compressor operates at the second operating frequency for the fourth preset time period, obtain the current indoor environmental temperature, and judge whether the absolute value of the difference between the current indoor environmental temperature and the theoretical indoor environmental temperature at this moment is greater than the first preset difference; if the absolute value of the difference is greater than the first preset difference, it is determined that the compressor cannot reach the set temperature after operating at the second operating frequency for the second preset time period, calculate the amount of cold and heat that needs to be compensated according to the heat radiation amount of the floor-to-ceiling window and the difference between the indoor temperature and the set temperature, and adjust the operating frequency of the compressor according to the amount of cold and heat that needs to be compensated.

[0010] It can be seen that when the air conditioner is in actual use, that is, in the automatic adjustment mode, the operating frequency of the compressor is determined according to the basic parameters of the room that are dynamically adjusted according to parameters, and the compressor operates at this operating frequency. At the same time, the difference between the measured indoor temperature change value and the theoretical value is monitored. If the difference is small, it means that the heat radiation of the floor-to-ceiling window has little impact on the indoor temperature and can be ignored. If the difference is large, the impact of the heat radiation of the floor-to-ceiling window on the indoor temperature needs to be considered, and the cooling or heating capacity that needs to be compensated is calculated, and then the operating frequency of the compressor is adjusted. Thereby avoiding the influence of the floor-to-ceiling window on heat exchange, ensuring the constancy of the indoor temperature, and always maintaining it at the most comfortable level. Effectively adjust the air conditioner power in the room according to quantitative and variable factors inside and outside the room, achieve precise temperature control, and improve user comfort. At the same time, by detecting the external environment in real time, precise control of the indoor temperature is achieved, especially in rooms equipped with large floor-to-ceiling windows, with remarkable effects and improved living comfort.

[0011] A further solution is that if the absolute value of the difference is less than or equal to the first preset difference, it is determined that the heat radiation of the floor-to-ceiling window has little impact on the indoor temperature, and the compressor is controlled to continue operating at the second operating frequency.

[0012] A further solution is that after the compressor continues to operate for the fifth preset time period, the current indoor ambient temperature is obtained, and it is judged whether the absolute value of the difference between the current indoor ambient temperature and the theoretical indoor ambient temperature at this moment is greater than the second preset difference; if so, the operating frequency of the compressor is adjusted; if not, the compressor is controlled to continue operating at the second operating frequency.

[0013] It can be seen that according to the two variables that have the greatest impact on the room, namely the heat radiation of the floor-to-ceiling window and the change in heat conduction caused by the change in outdoor temperature, temperature control in the room is carried out at two levels to meet the user's comfort requirements.

[0014] A preferred solution is that the calculation formula for the heat radiation quantity Q of the floor-to-ceiling window is: Q = E * A, where E is the light intensity passing through the glass; A is the surface area of the floor-to-ceiling window glass.

[0015] A further solution is that the air conditioner includes a light sensor, and the light sensor is used to detect the light intensity passing through the glass.

[0016] It can be seen that the light intensity passing through the glass can be detected by setting a light sensor, and then the heat radiation quantity of the floor-to-ceiling window can be calculated.

[0017] A further solution is that the light intensity passing through the glass is calculated by the following formula: E = I * Z, where I is the solar radiation intensity; Z is the proportion of the glass passing through the solar radiation, which depends on the material of the glass; the calculation formula for the solar radiation intensity I is: I = S 0 * cos(θ) * Ta, where S 0is the solar constant; θ is the solar altitude angle; Ta is the atmospheric transmittance of solar radiation; sin(θ) = sin(φ) * sin(δ) + cos(φ) * cos(δ) * cos(h); where φ is the geographical latitude, δ is the solar declination, and h is the local hour angle.

[0018] It can be seen that the solar radiation intensity can also be calculated through a formula. The solar radiation transmittance Ta is calculated by borrowing a physical model (such as MODTRAN) to obtain the atmospheric component concentration, temperature, and humidity from the network through the system. Finally, the solar radiation intensity I is obtained and compared with the solar radiation intensity monitored by the local weather station to ensure more accurate data.

[0019] A preferred solution is that the fluctuation range of the outdoor ambient temperature in the parameter dynamic adjustment mode is greater than or equal to the fluctuation range of the outdoor ambient temperature in the adaptive mode.

[0020] A further solution is to execute the automatic adjustment mode during the period from sunset to sunrise the next day. And / or, execute the parameter dynamic adjustment mode during the period from sunrise to sunset.

[0021] It can be seen that during the period with a relatively small fluctuation range of the outdoor temperature, such as the time from after sunset to before sunrise, entering the adaptive mode can avoid the influence of the outdoor temperature fluctuation on the heat exchange amount and ensure that the value of the operating frequency is adapted based on the room parameters themselves. During the period with a relatively large fluctuation range of the outdoor temperature, such as the time from after sunrise to before sunset, enter the parameter dynamic adjustment mode.

[0022] To achieve the above second object, the present invention provides an air conditioner, which includes a processor. When the processor executes the program stored in the memory, the above control method is implemented. Description of the Drawings

It should also be understood that terms defined in a general dictionary, such as those, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such herein.

[0031] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be regarded as part of the specification.

[0032] The air conditioner of this embodiment includes a processor, and the processor is used to implement the following control method when executing the program stored in the memory.

[0033] See Figures 1 to 3 , the air conditioner of this embodiment has an adaptive mode, a parameter dynamic adjustment mode, and an automatic adjustment mode.

[0034] After the air conditioner is installed, the basic parameters of the room need to be input through the client. The basic parameters of the room include the room area, room height, door and window area, the heat transfer coefficient of the doors, windows and walls, and the number of permanent residents in the room, etc.

[0035] Before the user first uses the air conditioner, the "adaptive mode" needs to be turned on. This mode will calculate the compressor operating frequency based on the above basic parameters of the room to achieve the best comfort. Whether it is the cooling or heating function, the system recommends executing the adaptive mode during the period from sunset to sunrise the next day (i.e., at night), during which the outdoor ambient temperature fluctuates less and the solar radiation outside the window is less. This can avoid the influence of outdoor temperature fluctuations on the heat transfer amount and ensure that the value of the operating frequency is adapted based on the room parameters themselves.

[0036] See Figure 1 , the adaptive mode includes the following steps:

[0037] First, execute step S11 to obtain the basic parameters of the room.

[0038] Next, execute step S12. According to the basic parameters of the room, calculate the first operating frequency of the compressor required to reach the first set temperature (such as 26°C) within the first preset time period.

[0039] After the adaptive mode, the basic parameters of the room can be automatically corrected through the parameter dynamic adjustment mode to ensure that the capacity output value of the air conditioner matches the basic parameters of the room, and then the indoor temperature can be controlled more precisely. In addition, in order to further reduce the possible errors in the initial settings, it is recommended that the user can enable the adaptive mode and the parameter dynamic adjustment mode multiple times. Each operation will help improve the accuracy and response speed of the system. The user can view and adjust these parameters in the setting menu to further optimize the usage experience. Preferably, the parameter dynamic adjustment mode is executed during the period from sunrise to sunset (i.e., during the day). The fluctuation range of the outdoor ambient temperature in the parameter dynamic adjustment mode is greater than or equal to the fluctuation range of the outdoor ambient temperature in the adaptive mode.

[0040] See Figure 2 , the parameter dynamic adjustment mode includes the following steps:

[0041] First, execute step S21 to control the compressor to operate at the first operating frequency obtained in the above automatic adjustment mode for the second preset time period.

[0042] Next, perform step S22 to obtain the current indoor ambient temperature and determine whether the difference between the current indoor ambient temperature and the theoretical indoor ambient temperature at this moment is greater than a preset temperature difference. The theoretical current indoor ambient temperature can be obtained in the following way: within a preset time period, the air conditioner can change from the first temperature to the set temperature. Assuming that the indoor and outdoor environmental factors remain unchanged and the operating frequency of the air conditioner is constant, draw the temperature prediction curve in the room, and obtain the theoretical indoor ambient temperature value corresponding to the corresponding moment according to the operating time.

[0043] If the difference between the current indoor ambient temperature and the theoretical indoor ambient temperature at this moment is greater than the preset temperature difference, then perform step S23 to automatically correct the basic parameters of the room.

[0044] When the air conditioner is in actual use, the air conditioner executes the automatic adjustment mode.

[0045] See Figure 3 , after entering the automatic adjustment mode, first perform step S31 to dynamically adjust the basic parameters of the room corrected by the mode according to the parameters, and calculate the second operating frequency of the compressor required to reach the set temperature within the third preset time period.

[0046] Next, perform step S32 to control the compressor to operate at the second operating frequency for the fourth preset time period.

[0047] Next, perform step S33 to obtain the current indoor ambient temperature, and determine whether the absolute value of the difference between the current indoor ambient temperature and the theoretical indoor ambient temperature at this moment is greater than the first preset difference; the theoretical current indoor ambient temperature can be obtained by the above method of drawing the temperature prediction curve.

[0048] If the absolute value of the difference is greater than the first preset difference, it means that the heat radiation of the floor-to-ceiling window has a greater impact on the indoor temperature, then perform step S34 to determine that the compressor cannot reach the set temperature after operating at the second operating frequency for the second preset time period, and calculate the cooling and heating amounts that need to be compensated according to the heat radiation amount of the floor-to-ceiling window and the difference between the indoor temperature and the set temperature, and adjust the operating frequency of the compressor according to the cooling and heating amounts that need to be compensated.

[0049] Next, perform step S35. After the compressor continues to operate at the adjusted operating frequency for the sixth preset time period, perform step S36 to obtain the current indoor ambient temperature, and determine whether the absolute value of the difference between the current indoor ambient temperature and the theoretical indoor ambient temperature at this moment is greater than the second preset difference. Preferably, the second preset difference is equal to the first preset difference.

[0050] If so, return to step S34 to calculate the cooling and heating amounts that need to be compensated, and adjust the operating frequency of the compressor according to the cooling and heating amounts that need to be compensated.

[0051] If not, then execute step S37 to control the compressor to continue operating at the operating frequency adjusted in step S34.

[0052] If the absolute value of the difference is less than or equal to the first preset difference, it indicates that the heat radiation of the floor-to-ceiling window has little influence on the indoor temperature, and the influence of the heat radiation of the floor-to-ceiling window can be not considered. Then execute step S38 to determine that the influence of the heat radiation of the floor-to-ceiling window on the indoor temperature is small, and control the compressor to continue operating at the second operating frequency.

[0053] The compressor continues to operate at the second operating frequency for the fifth preset time period. Then, execute step S37 to obtain the current indoor ambient temperature, and determine whether the absolute value of the difference between the current indoor ambient temperature and the theoretical indoor ambient temperature at this moment is greater than the third preset difference. Preferably, the third preset difference is equal to the first preset difference.

[0054] If so, then execute step S34 to calculate the cooling and heating amounts that need to be compensated, and adjust the operating frequency of the compressor according to the cooling and heating amounts that need to be compensated.

[0055] If not, then execute step S39 to control the compressor to continue operating at the second operating frequency.

[0056] During the actual use of the air conditioner, the operating frequency of the compressor is continuously and dynamically adjusted to ensure a more stable indoor temperature while effectively reducing energy consumption. The automatic adjustment mode can perform indoor temperature control from two aspects according to the two variables that have the greatest impact on the room, namely the heat radiation of the floor-to-ceiling window and the change in heat conduction caused by the change in outdoor temperature, to meet the comfort requirements of users.

[0057] The calculation formula for the heat radiation amount Q of the floor-to-ceiling window is: Q = E * A, where E is the light intensity passing through the glass; A is the surface area of the floor-to-ceiling window glass. In this embodiment, the air conditioner includes a light sensor for detecting the light intensity passing through the glass. In other embodiments, the light intensity passing through the glass can also be calculated by the following formula: E = I * Z, where I is the solar radiation intensity; Z is the proportion of the glass passing through the solar radiation, which depends on the material of the glass; the calculation formula for the solar radiation intensity I is: I = S 0 * cos(θ) * Ta, where S 0 is the solar constant; θ is the solar altitude angle; Ta is the transmittance of the atmosphere to solar radiation; sin(θ) = sin(φ) * sin(δ) + cos(φ) * cos(δ) * cos(h); where φ is the geographical latitude; δ is the solar declination; h is the local hour angle. The solar radiation transmittance Ta is calculated by borrowing a physical model (such as MODTRAN) to obtain the atmospheric component concentration, temperature, and humidity from the network through the system. Finally, the solar radiation intensity I is obtained and compared with the solar radiation intensity monitored by the local meteorological station to ensure more accurate data.

[0058] As can be seen from the above, the air conditioner of the present invention has an adaptive mode and a parameter dynamic adjustment mode. In the adaptive mode, the air conditioner can calculate the heat exchange amount required to reach the first set temperature within the first preset time period based on the basic parameters of the room input by the client, and then determine the operating frequency of the compressor, which is a theoretical value. After entering the parameter dynamic adjustment mode, after controlling the compressor to operate at the first operating frequency obtained in the adaptive mode for the second preset time period, it is judged whether the current indoor environmental temperature can reach the theoretical indoor environmental temperature at this moment, that is, if the second preset time period is equal to the first preset time period, it is seen whether the current indoor environmental temperature can reach the set value. If the current indoor environmental temperature cannot reach the theoretical indoor environmental temperature at this moment, the basic parameters of the room are automatically corrected. That is, the parameter dynamic adjustment mode only considers the influence of parameters such as walls on the heat exchange performance, and does not consider the influence of the heat radiation of floor-to-ceiling windows on the heat exchange performance, so as to realize the correction of the basic parameters of the room according to the heat exchange situation.

[0059] Thus, the operating frequency of the air conditioner can be matched with the basic parameters of the room, avoiding the situations in the prior art where a smaller room may cause overcooling or overheating and a larger room may not achieve the ideal temperature adjustment effect. Therefore, the intelligent air conditioner of the present invention can not only provide a more stable indoor temperature, but also effectively reduce energy consumption, and the air conditioner adaptive mode can more closely meet different application scenarios within the actual capacity of the air conditioner. Through continuous monitoring and intelligent feedback mechanisms, the system can meet the current social advocacy of a green and low-carbon lifestyle while ensuring comfort.

[0060] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
