Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to air conditioning control methods, devices, air conditioners, and storage media. Background Technology

[0002] With the development of air conditioning technology, air conditioners have become an indispensable appliance in people's daily lives. Related technologies include operating modes such as sleep mode, energy-saving mode, and rapid cooling or heating mode. When the air conditioner operates at high power, the pressure inside the compressor's compression chamber is at a high level.

[0003] Currently, when existing air conditioners exit the aforementioned operating mode, the pressure inside the compressor chamber drops sharply. This sudden drop in pressure can cause an imbalance in the internal pressure of components such as the condenser and compressor, potentially leading to damage to these components.

[0044] The technical solution provided by the embodiments of the present invention can include the following beneficial effects: In response to an instruction to exit the target mode, the air conditioner determines the compressor's frequency reduction rate based on the ambient temperature outside the target space and / or the internal temperature, ensuring the frequency reduction rate matches the environmental conditions and reducing the risk of instantaneous pressure imbalance in the compression chamber due to excessively high external or indoor temperature differences. By controlling the compressor frequency to decrease from the current frequency to a first intermediate frequency according to the matched frequency reduction rate, and operating at this first intermediate frequency for a first preset duration, the pressure in the compression chamber can smoothly transition from a high-pressure state to a lower intermediate pressure state. This step-by-step pressure reduction process reduces the impact on the air conditioning system caused by sudden pressure changes. After the first preset duration, the compressor frequency is further reduced from the first intermediate frequency to the target frequency, allowing the pressure in the compression chamber to further smoothly decrease to the normal operating pressure. Through this step-by-step, controllable frequency reduction and pressure release method, a smooth pressure transition is achieved when exiting the target mode, thus reducing sudden pressure drops in the compression chamber, thereby improving the stability and reliability of the air conditioner operation and reducing the likelihood of damage to air conditioning components.

[0045] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the invention. Attached Figure Description

[0053] Some embodiments of the present invention will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding the invention. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding the invention, except for operations that must be performed in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0054] Considering the aforementioned problems with existing air conditioning control methods, this application proposes a method for gradually reducing pressure on components such as the compressor during the exit from the target mode. Through a gradual and controllable frequency reduction and pressure release mechanism, a smooth pressure transition is achieved when exiting the target mode. This reduces sudden pressure drops in the compression chamber, thereby improving the stability and reliability of air conditioning operation, reducing damage to air conditioning components, and ensuring their service life.

[0055] The air conditioner includes a compressor and a fan. The air conditioner has a target mode. In the target mode, the compressor operates at a frequency higher than a preset frequency, and / or the fan operates at a speed higher than a preset speed. The preset frequency is the maximum operating frequency of the compressor in other modes, and the preset speed is the maximum operating speed of the fan in other modes; other modes are modes other than the target mode.

[0056] Taking the target mode as the Frenzy Mode as an example, in Frenzy Mode, the operating frequency of the air conditioner compressor is greater than the preset frequency and / or the operating speed of the fan (indoor or outdoor) is greater than the preset speed (the preset frequency is the maximum value of the compressor operating frequency in other modes, and the preset speed is the maximum operating speed of the fan in other modes, and other modes are modes other than Frenzy Mode).

[0057] Other modes can be modes that meet noise requirements. For example, other modes may include gentle breeze mode, normal cooling / heating mode, and the highest fan speed setting. When the air conditioner is in these modes, the noise generated by the air conditioner needs to be lower than the preset noise level. For example, if the preset noise level of the indoor unit is 42 decibels and the preset noise level of the outdoor unit is 52 decibels, when the air conditioner is in these modes, the compressor and the indoor and outdoor fans will generate noise, but the noise levels of the indoor and outdoor units will still be within the preset noise levels of the indoor and outdoor units, respectively.

[0058] The preset noise levels of the indoor and outdoor units refer to the noise values ​​of the indoor and outdoor units as indicated on the nameplates, based on national standard testing.

[0059] In some embodiments, when the compressor's operating frequency is greater than a preset frequency, it indicates that the present invention targets the air conditioner's "extreme" mode. Specifically, the preset frequency is not the physical limit frequency that the compressor's hardware structure can withstand, but rather the maximum frequency among the normal frequencies set by the air conditioner in other modes to balance daily energy efficiency, equipment wear and tear, and operating noise. This normal frequency is based on scenarios of stable operation rather than extreme performance.

[0060] The core characteristic of the "Rampage Mode" is that the compressor operates at a frequency higher than the preset frequency. This is because the primary requirement of Rampage Mode is to rapidly reduce indoor temperature differences, thus exceeding the frequency limitations of normal mode. The compressor operates at a higher frequency to maximize cooling / heating capacity. In other words, Rampage Mode overcomes noise limitations to achieve maximum cooling or heating effects. This ensures that while the compressor's operating frequency exceeds the conventional upper limit, it remains below the compressor's hardware limits, achieving a balance between high-frequency efficiency and operational safety, precisely matching the usage scenarios of Rampage Mode.

[0061] In all operating modes except for the "Rampage" mode, the compressor's highest operating frequency at maximum load is n1. In Rampage mode, the compressor's operating frequency is n2. Under the same operating conditions, n2 > n1, where n1 is less than the upper frequency limit indicated on the compressor's nameplate, and n2 is less than or equal to the upper frequency limit indicated on the compressor's nameplate. For example, in all operating modes except for Rampage mode, taking a certain model of air conditioner as an example, in cooling mode, n1 is (80-90) Hz, and in heating mode, n1 is (100-110) Hz. In Rampage mode, in cooling mode, n2 is (91-140) Hz, and in heating mode, n2 is (111-140) Hz.

[0062] Taking a 1.5 horsepower air conditioner as an example, in all operating modes except for the "Raging Mode", the compressor operates at a maximum frequency of 108 Hz when at maximum load, reaching 77% of the upper limit of the compressor nameplate frequency. In "Raging Mode", the compressor is allowed to operate at a frequency exceeding 108 Hz, but less than or equal to 140 Hz. That is, in "Raging Mode", the compressor's maximum operating frequency can reach 100% of the upper limit of the compressor nameplate frequency.

[0063] The "Rampage Mode" can overcome the limitations of other modes, with at least one of the operating frequency and fan speed exceeding the preset values, or both simultaneously. However, compared to other modes, it also approaches the hardware limits of the compressor and fan. Prolonged operation may cause the temperature of electrical components and control systems to exceed their limits. Therefore, within the design margin, Rampage Mode is allowed to run for 5-60 minutes before exiting. The duration of Rampage Mode can be set by the user or left as a default value.

[0064] The embodiments described in the following examples of the present invention do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0065] Figure 1 This is a flowchart illustrating an air conditioning control method according to some embodiments of the present invention. Figure 2 This is a schematic diagram illustrating the structure of an air conditioner according to some embodiments of the present invention. The air conditioner may include a compressor. The compressor may include a compression chamber. The air conditioner can regulate the environment within a target space in a target mode.

[0066] In some embodiments, the target mode can be an operating mode with an output intensity higher than the normal mode. This target mode could be, for example, the aforementioned "frenzy mode," or a rapid cooling or heating mode, or a powerful mode, etc.

[0067] The aforementioned target space can be, for example, an indoor space where the air conditioner is installed, such as a room or living room. The phrase "adjusting the environment within the target space" can refer, for example, to adjusting the temperature and / or humidity within the target space.

[0068] The operating frequency of the aforementioned compressor can affect the pressure of the refrigerant within its compression chamber. It should be understood that this application does not limit the type, operating mode, or structure of the compressor or compression chamber. The compressor and compression chamber can refer to any existing air conditioning compressor, and will not be elaborated upon here.

[0069] This air conditioning control method can be used in an air conditioner. In some embodiments, the air conditioner may include a processing module (also referred to as a processor, controller, or the main control board of the air conditioner, etc.). The executing entity of the air conditioning control method can be the processing module (or in some embodiments, the executing entity of the air conditioning control method can also be referred to as the air conditioner). The processing module can be, for example, any electronic module with processing capabilities, such as a microprocessor, an application-specific integrated circuit (ASIC), a digital signal processor (DSP), etc. Figure 1 As shown, the air conditioning control method may include the following steps:

[0070] In step S11, in response to the command to exit the target mode, the compressor's frequency reduction rate is determined based on the ambient temperature outside the target space and / or the temperature inside the target space.

[0071] Optionally, the aforementioned command to exit the target mode can be a "command to indicate exiting the target mode" manually triggered by the user through a remote control, a smart terminal (such as a mobile phone, smartwatch, or any other terminal device) application, or the air conditioner panel. Alternatively, the command to exit the target mode can also be a "command to indicate exiting the target mode" automatically generated by the air conditioner when the conditions for automatically exiting the target mode are met (such as the target mode running time reaching a preset running time, or the temperature in the target room reaching a set temperature value, etc.).

[0072] For example, taking the air conditioner determining the compressor's frequency reduction rate based on the ambient temperature outside the target space as an example, the air conditioner may optionally first obtain the ambient temperature outside the target space. For example, the air conditioner can obtain the ambient temperature outside the target space through a temperature sensor installed outdoors. Alternatively, the air conditioner may also obtain weather forecast information through smart home device linkage (or through its own network communication function) and use the temperature forecast therein as the ambient temperature outside the target space.

[0073] An air conditioner can determine the compressor's frequency reduction rate based on the ambient temperature and the mapping relationship between temperature and frequency reduction rate. This frequency reduction rate can be negatively correlated with the ambient temperature. For example, the higher the ambient temperature, the lower the frequency reduction rate can be; the lower the ambient temperature, the higher the frequency reduction rate can be. By making the frequency reduction rate negatively correlated with the ambient temperature, the compressor frequency can be reduced more gradually in high-temperature environments, thereby mitigating the risk of high system pressure caused by high ambient temperatures and further avoiding sudden pressure changes.

[0074] Taking the example of an air conditioner determining the compressor's frequency reduction rate based on the temperature within a target space, the air conditioner can optionally first acquire the temperature within the target space. For example, the air conditioner can acquire the temperature within the target space using a temperature sensor installed indoors. Exemplarily, the air conditioner can determine the frequency reduction rate based on the temperature difference between the target space temperature and the set temperature, and the mapping relationship between the temperature difference and the frequency reduction rate. The set temperature can be the desired indoor temperature value. A larger temperature difference (indicating a greater gap to reaching the desired temperature), i.e., a larger current load, allows for a slower frequency reduction rate, resulting in a more gradual decrease in pressure. Conversely, a smaller temperature difference allows for a relatively faster frequency reduction. In other words, the frequency reduction rate can be negatively correlated with the temperature difference.

[0075] Alternatively, the air conditioner can also exit the target mode by determining the compressor's throttling rate based on the ambient temperature outside the target space and the temperature inside the target space.

[0076] In step S12, the frequency of the compressor is controlled to decrease from the current frequency to the first intermediate frequency according to the frequency reduction rate.

[0077] It should be understood that this application does not limit the magnitude of the operating frequency (i.e., the current frequency) of the compressor in the target mode.

[0078] Optionally, the air conditioner can control the compressor to uniformly reduce its speed to the first intermediate frequency according to the aforementioned frequency reduction rate. For example, the first intermediate frequency can be a frequency pre-stored in the air conditioner that is lower than the target mode's operating frequency. For example, the first intermediate frequency can be a specific frequency value that is lower than the current frequency but higher than the normal operating frequency. This first intermediate frequency can be used as a buffer phase during the frequency reduction process.

[0079] In step S13, the compressor is controlled to run at the first intermediate frequency for a first preset duration.

[0080] When the compressor operates at the first intermediate frequency, the first pressure in the compression chamber may be less than the second pressure in the compression chamber when the compressor operates at the aforementioned current frequency.

[0081] For example, the first preset duration can be a duration calibrated offline by a technician and pre-stored in the air conditioner controller. For example, the first preset duration can be 30 seconds.

[0082] In step S14, after a first preset time period, the frequency of the compressor is controlled to decrease from the first intermediate frequency to the target frequency.

[0083] When the compressor operates at the target frequency, the third pressure in the compression chamber can be less than the first pressure.

[0084] Optionally, the target frequency can be the maximum frequency of the compressor in other modes. These other modes can be operating modes of the air conditioner other than the target mode, such as automatic mode, energy-saving mode, etc. Alternatively, the target frequency can be any frequency that will not damage the compressor's operation.

[0085] Optionally, the target frequency can be a frequency calibrated offline by a technician and pre-stored in the air conditioner controller. Alternatively, the target frequency can also be the compressor frequency determined by the air conditioner based on the user-set desired indoor temperature value.

[0086] Since the target frequency is lower than the first intermediate frequency, when the compressor operates at the target frequency, the third pressure in its compression chamber can be further reduced, becoming less than the first pressure at the first intermediate frequency. Through this method, the compressor frequency achieves a gradual decrease from the current frequency to the first intermediate frequency, and then from the first intermediate frequency to the target frequency.

[0087] In this embodiment, the air conditioner, in response to the command to exit the target mode, determines the compressor's frequency reduction rate based on the ambient temperature outside the target space and / or the internal temperature, ensuring that the frequency reduction rate matches the environmental conditions. This reduces the risk of instantaneous pressure imbalance in the compression chamber caused by high external temperatures or large indoor temperature differences. By controlling the compressor frequency to decrease from the current frequency to a first intermediate frequency according to the matched frequency reduction rate, and operating at this first intermediate frequency for a first preset duration, the pressure in the compression chamber can smoothly transition from a high-pressure state (i.e., the second pressure) to a lower intermediate pressure state (i.e., the first pressure). This step-by-step pressure reduction process reduces the impact on the air conditioning system caused by sudden pressure changes. After the first preset duration, the compressor frequency is further reduced from the first intermediate frequency to the target frequency, allowing the pressure in the compression chamber to further smoothly decrease to the normal operating pressure (the third pressure). Through this step-by-step, controllable frequency reduction and pressure release method, a smooth pressure transition is achieved when exiting the target mode. Therefore, sudden pressure drops in the compression chamber are reduced, thereby improving the stability and reliability of the air conditioner operation and reducing the likelihood of damage to air conditioning components.

[0088] The following provides a detailed explanation of how an air conditioner determines the compressor's throttling rate based on the ambient temperature outside the target space and / or the temperature inside the target space:

[0089] Taking the determination of the compressor's frequency reduction rate based on the ambient temperature outside the target space as an example, one possible implementation is that the air conditioner can first determine the temperature range of the ambient temperature. Then, the air conditioner can determine the compressor's frequency reduction rate based on this temperature range and the mapping relationship between the temperature range and the frequency reduction rate. This frequency reduction rate can be negatively correlated with the aforementioned ambient temperature.

[0090] For example, the air conditioner can use a temperature sensor deployed on the outdoor unit to collect the ambient temperature outside the target space. The air conditioner can then compare this ambient temperature with a number of preset temperature thresholds to determine the temperature range in which the ambient temperature falls.

[0091] For example, the aforementioned temperature range may include: a low temperature range (e.g., below 25°C), a medium temperature range (e.g., 25°C to 30°C), and a high temperature range (e.g., above 35°C). This application does not limit the method of dividing the temperature range, the number of temperature ranges, or the boundary values ​​of the temperature ranges.

[0092] For example, the mapping relationship between the above temperature range and the frequency reduction rate can be shown in Table 1 below:

[0093] Table 1

[0094]

[0095] Taking the mapping relationship shown in Table 1 as an example, the temperature values ​​in interval 1 are all lower than the temperature values ​​in interval 2, and the temperature values ​​in interval 2 are all lower than the temperature values ​​in interval 3. Correspondingly, the frequency reduction rate 1 is greater than the frequency reduction rate 2, and the frequency reduction rate 2 is greater than the frequency reduction rate 3. Assuming the ambient temperature falls within interval 2, the air conditioner can determine the compressor's frequency reduction rate as rate 2.

[0096] Using the above method, the higher the outer ring temperature (the ambient temperature outside the target space), the lower the compressor frequency reduction rate; and the lower the outer ring temperature, the higher the compressor frequency reduction rate can be. This allows the air conditioner to adopt a smoother frequency reduction strategy in high-temperature environments, mitigating the risk of excessively rapid pressure release and impact caused by high cooling demand and high air conditioning system pressure, thereby improving the reliability of air conditioning components when exiting the target mode.

[0097] As another possible implementation, taking the determination of the compressor's throttling rate based on the ambient temperature outside the target space and the temperature inside the target space as an example, before determining the compressor's throttling rate based on the ambient temperature outside the target space and the temperature inside the target space, the air conditioner can, for example, first determine the step-by-step exit conditions for the target mode based on a set temperature. Then, when the temperature inside the target space meets these step-by-step exit conditions, the air conditioner can determine the compressor's throttling rate based on the aforementioned ambient temperature.

[0098] In some embodiments, the air conditioner may receive the desired temperature in the target space input by the user via a remote control, smart terminal application, or the air conditioner's control panel, and use it as the set temperature.

[0099] For example, the aforementioned step-by-step exit condition could be: the temperature within the target space is greater than or equal to the sum of the set temperature and a preset temperature offset value (e.g., 0℃, 1℃, 2℃, or a variable range value). When the temperature within the target space meets this step-by-step exit condition, it indicates that the temperature within the target space has not yet approached the neighborhood of the set temperature, and the target mode needs to be maintained for a period of time so that the temperature within the target space can approach the neighborhood of the set temperature as soon as possible.

[0100] By exiting the target mode step by step when the temperature in the target space meets the step-by-step exit conditions, the cooling (or heating) capacity of part of the target mode is maintained during the exit process, so that the temperature in the target space can approach the neighborhood of the set temperature as soon as possible. This ensures the accuracy of temperature adjustment in the target space while guaranteeing the step-by-step exit of the target mode.

[0101] In some embodiments, the air conditioner may also control the compressor frequency to decrease from the current frequency to the target frequency when the temperature in the target space does not meet the step-by-step exit conditions.

[0102] For example, taking the cooling mode as an example, the situation where the step-by-step exit condition is not met can be: the temperature in the target space is less than the sum of the set temperature and the preset temperature offset value. When the temperature in the target space does not meet the above step-by-step exit condition, it means that the temperature in the target space is close to the user's expected comfortable temperature range. Therefore, the air conditioner can directly control the compressor's operating frequency to decrease from the current frequency to the target frequency (the target frequency can be, for example, the maximum frequency of the normal operating mode).

[0103] Using the above method, if the temperature in the target space does not meet the above-mentioned step-by-step exit conditions, it means that it is not necessary to exit the target mode by performing the aforementioned step-by-step exit method. Therefore, the frequency of the compressor can be controlled to be reduced from the current frequency to the target frequency so that the air conditioner can operate at the target frequency.

[0104] As one possible implementation, the aforementioned target frequency can be the maximum frequency of the compressor in other modes. These other modes can be any operating mode of the air conditioner other than the target mode. For example, these other modes could be sleep mode, normal mode, comfort mode, energy-saving mode, etc. After controlling the compressor frequency to decrease from the first intermediate frequency to the target frequency, the air conditioner can also control the compressor to run at the target frequency for a second preset duration. After this second preset duration, the air conditioner can control the compressor to operate in the aforementioned other modes.

[0105] Optionally, the second preset duration can range from, for example, 1 minute to 10 minutes. This second preset duration can be pre-stored in the air conditioner processor. This second preset duration allows the air conditioner to operate at a relatively stable and higher capacity output level (the compressor's maximum frequency in other modes) for a period of time after experiencing a pressure balance phase following the exit from the target mode and a pause at an intermediate frequency. This method further smooths out pressure changes in the air conditioning system and keeps the temperature in the target space stable during the exit from the target mode, reducing the possibility of reverse fluctuations in room temperature caused by immediately switching to a lower frequency, thus improving the user experience.

[0106] For example, when the air conditioner controls the compressor to run in the other modes described above, it can determine the compressor's operating frequency based on the difference between the current temperature in the target space and the user-set temperature, using the control algorithm built into the other modes (e.g., any existing air conditioner control algorithm), and control the compressor to run at that operating frequency.

[0107] In this embodiment, by setting the target frequency to the maximum frequency of other modes, and running for a second preset time after dropping to the target frequency before switching to other modes, the compressor first runs stably at the upper limit of its normal capacity for a period of time during the process of exiting the target mode. This provides additional buffering and balancing time for the system pressure, further smoothing the intermediate process of transitioning from a high-load state to a normal mode. While further improving the stability of the system operating pressure, it also reduces the reverse fluctuation of room temperature caused by immediately switching to a lower frequency, thus improving the user experience.

[0108] As one possible implementation, before determining the compressor's frequency reduction rate based on the ambient temperature outside the target space and / or the temperature inside the target space, the air conditioner may first determine whether the current frequency of the air conditioner is greater than the target frequency described in any of the foregoing embodiments.

[0109] For example, when the current frequency is less than or equal to the target frequency, the air conditioner can control the compressor to operate in other modes. When the current frequency is greater than the target frequency, the air conditioner can perform the aforementioned step of "determining the compressor's frequency reduction rate based on the ambient temperature outside the target space and / or the temperature inside the target space".

[0110] When the current frequency is less than or equal to the target frequency, it indicates that the compressor is not operating at a higher frequency when the air conditioner responds to the command to exit the target mode. For example, in the later stages of target mode operation, the temperature in the target space has approached the set temperature, and the compressor has already started to reduce its frequency (or due to other control constraints, such as system high-load operation time limits), resulting in a lower current compressor frequency in the later stages of target mode operation, meaning the pressure in the compression chamber is not high. Therefore, by using the above method, when the current frequency is less than or equal to the target frequency, controlling the compressor to operate in other modes improves the efficiency of the air conditioner entering other modes while ensuring that there are no sudden pressure changes in the compression chamber.

[0111] When the current frequency is higher than the target frequency, it indicates that the air conditioner is under high load. Directly switching to other modes would pose a risk of sudden pressure changes and indoor temperature fluctuations. Therefore, the aforementioned gradual frequency reduction air conditioner control method can be implemented to improve pressure stability during the target mode exit process.

[0112] The above method can determine whether to execute the step-down frequency control method provided in this application based on the relationship between the current frequency and the target frequency, thereby improving the flexibility of target mode exit control and improving the efficiency of air conditioning to enter other modes of operation while ensuring that there is no pressure change in the compression chamber. When there may be a pressure change in the compression chamber, the aforementioned step-down frequency control method is executed to improve the pressure stability of the target mode exit process.

[0113] As one possible implementation, the air conditioner may further include an indoor unit. This indoor unit may include a first fan. After controlling the compressor frequency to decrease from the current frequency to a first intermediate frequency according to a frequency reduction rate, the air conditioner may further control the first fan speed to decrease to the maximum speed of the first fan in other modes when the current speed of the first fan is greater than the target speed. The air conditioner can control the first fan to operate in the aforementioned other modes while the compressor is operating in other modes.

[0114] The aforementioned first fan can be used to drive airflow through the target space for heat exchange and to deliver the regulated air into the target space. Taking the target mode as the "violent mode" as an example, in the target mode, the first fan can operate at a higher speed to match the high-frequency compressor and achieve rapid temperature adjustment. It should be understood that this application does not limit the structure of the first fan, indoor unit, etc.

[0115] For example, the target speed may be the maximum speed of the first fan in the other modes mentioned above. Alternatively, the target speed may be pre-stored in the air conditioning processor.

[0116] When the current speed is greater than the target speed, it indicates that the air volume of the indoor unit is currently large. By controlling the speed of the first fan to be reduced to the maximum speed of the first fan in other modes, excessive sudden changes in the air volume of the first fan are avoided, the stability of the air volume of the indoor unit during the exit from the target mode is improved, and the user experience is enhanced.

[0117] Optionally, the above-described method of controlling the first fan to operate in other modes can refer to any existing method for controlling the speed of the indoor unit fan in an air conditioning operating mode, and this application does not limit it in this regard. By controlling the first fan to switch to other modes when the compressor is running in other modes, the speed of the first fan is no longer fixed at its maximum speed, but can be adjusted according to the rules of other modes, thus improving the flexibility of the first fan control.

[0118] Optionally, after the air conditioner controls the compressor frequency to decrease from the current frequency to the first intermediate frequency according to the frequency reduction rate, if it is determined that the current speed of the first fan is less than or equal to the target speed, the first fan can be directly controlled to operate in the other modes mentioned above.

[0119] As one possible implementation, the indoor unit may also include an air deflector. The air conditioner can also control the air deflector to achieve an anti-blowing function in the target mode.

[0120] For example, before the air conditioner determines the compressor's throttling rate based on the ambient temperature outside the target space and / or the temperature inside the target space in response to the command to exit the target mode, it can also determine the location of a human body in the target space in response to the command to enter the target mode.

[0121] Optionally, the instruction to enter the target mode can be manually triggered by the user. For example, the air conditioner can receive an instruction from the user to select the target mode via a remote control, mobile application, smart speaker, etc. Alternatively, the instruction to enter the target mode can also be automatically triggered by the air conditioner based on specific conditions (such as detecting that the difference between the indoor temperature and the set temperature is too large). It should be understood that this application does not limit the source of the instruction to enter the target mode.

[0122] For example, an air conditioner can locate a person in a target space by detecting the infrared heat emitted by the human body using an infrared thermal imaging sensor installed on the indoor unit. Alternatively, the air conditioner can also identify the location of a person in the target space by emitting and receiving electromagnetic waves using a millimeter-wave radar sensor built into the indoor unit to detect the distance and movement of objects in the room. Furthermore, the air conditioner can also identify the location of a person in the target space using a camera and any existing human position positioning visual recognition algorithm. It should be understood that this application does not limit how the air conditioner determines the location of a person in the target space.

[0123] Then, the air conditioner can control the angle of the air guide vane to the target angle based on the position of a person within the target space. When the air guide vane is at the target angle, the air outlet area of ​​the indoor unit is the target area. The position of the person is outside this target area. In other words, the target area is the area excluding the position of the person.

[0124] For example, after the air conditioner enters the target mode, if a person is located on the left side of the target space, the air conditioner can control the target angle of the air guide vane to rotate to the right by a preset angle, so that the air outlet of the indoor unit faces the right side of the target space. Taking the person being located in the center of the target space (or if there are people in every direction within the target space) as an example, the air conditioner can, for instance, control the target angle of the air guide vane to the maximum upward angle to avoid strong airflow blowing directly on the person. Alternatively, if it is determined that there are no people in the target space, the air conditioner can, for instance, control the target angle of the air guide vane to any preset angle.

[0125] In this embodiment, when entering the target mode, the position of the human body in the target space is first determined and the angle of the air guide plate is controlled so that the air outlet area avoids the human body, reducing the discomfort caused by high-speed cold / hot air blowing directly on the human body during the operation of the target mode, and improving the user experience during the operation of the target mode.

[0126] As one possible implementation, the air conditioner can also control the fan speed of the outdoor unit based on the condenser pipe temperature.

[0127] For example, the air conditioner may also include an outdoor unit and a condenser. The outdoor unit may include a second fan. In response to a command to exit the target mode, the air conditioner may also control the second fan to operate at its current speed for a third preset duration. After the third preset duration, the air conditioner may acquire the condenser's pipe temperature.

[0128] In some embodiments, the second fan described above can be used to drive airflow through the condenser, so as to dissipate heat (cooling mode) or absorb heat (heating mode) from the high-temperature, high-pressure refrigerant gas inside the condenser. In the target mode, the second fan can, for example, operate at a higher speed to meet the heat exchange requirements of the condenser under high load. It should be understood that this application does not limit the structure of the outdoor unit, condenser, and second fan described above.

[0129] For example, the current speed of the second fan can be the speed of the second fan when the air conditioner receives the instruction to exit the target mode. Optionally, the aforementioned third preset duration can be pre-stored in the air conditioner processor. For example, the value range of the third preset duration can be, for example, 1 minute to 10 minutes.

[0130] Alternatively, the air conditioner can measure the surface temperature or internal refrigerant temperature of a specific pipe section of the condenser (e.g., the middle or outlet of the condenser) using a temperature sensor (e.g., a pipe temperature probe), and use this temperature as the condenser's pipe temperature. The condenser's pipe temperature can be used to characterize the condenser's operating load and heat dissipation status.

[0131] The air conditioner can compare the pipe temperature with the frequency-limiting temperature in the other modes mentioned above. This frequency-limiting temperature refers to the safe threshold temperature of the condenser pipe temperature under the other modes. When the pipe temperature is greater than or equal to this frequency-limiting temperature, it indicates that the condenser's heat dissipation load is still high. In this case, reducing the fan speed may lead to insufficient condenser heat dissipation, causing the condensing pressure to rise again, resulting in pressure imbalance in the air conditioning system. When the pipe temperature is less than this frequency-limiting temperature, it indicates that the condenser's heat dissipation load is low. In this case, reducing the fan speed can still meet the condenser's heat dissipation needs, and the air conditioner is operating within a safe range.

[0132] Therefore, when the temperature of the duct is lower than the frequency-limiting temperature in the other modes mentioned above, the air conditioner can control the speed of the second fan to decrease from the current speed to the maximum speed of the second fan in the other modes mentioned above.

[0133] For example, the maximum speed of the second fan in other modes can refer to the maximum speed of the second fan in any existing air conditioning operating mode, which will not be elaborated here. The maximum speed of the second fan in the aforementioned other modes can, for example, be pre-stored in the air conditioner's processor.

[0134] By using the above method, when the pipe temperature is lower than the frequency-limiting temperature in the other modes mentioned above, the speed of the second fan is controlled to decrease from the current speed to the maximum speed of the second fan in the other modes mentioned above. This ensures that the cooling demand of the condenser can be met even when the fan speed is reduced, while also reducing the situation where the speed of the second fan changes too much. Therefore, the stability of the air conditioner exiting the target mode is further improved.

[0135] Optionally, if the pipe temperature is greater than or equal to the frequency-limiting temperature in the aforementioned other modes, the air conditioner may, for example, keep the speed of the second fan unchanged at the current speed and continue to judge the pipe temperature and the frequency-limiting temperature in the aforementioned other modes until the pipe temperature is less than the frequency-limiting temperature in the aforementioned other modes, and then control the speed of the second fan to decrease from the current speed to the maximum speed of the second fan in the aforementioned other modes.

[0136] Optionally, after the air conditioner controls the second fan's speed to decrease from its current speed to the maximum speed of the second fan in the other modes for a fourth preset period of time, it can then control the second fan's speed to operate at the speed of the second fan in the other modes. Optionally, the method for controlling the second fan's speed to operate at the speed of the second fan in the other modes can refer to any existing method for controlling the speed of the second fan in an air conditioner, and will not be elaborated here.

[0137] The air conditioning control method provided in this application is illustrated below:

[0138] For example, taking the target mode as the "frenzy mode," after automatically or manually exiting frenzy mode, the compressor frequency can be reduced by lowering the compressor frequency to minimize fluctuations in indoor capacity output and pressure. A specific method could be as follows:

[0139] 1. If the temperature within the inner loop (i.e., the temperature in the target space) is greater than the set temperature (T) plus the exit temperature (e.g., 0℃-2℃), the frequency will decrease at a rate of X Hz / s until the dwell time on the platform is reached (e.g., 30~200s), then the frequency will decrease to the upper limit of the normal frequency, and the frequency open-loop control will run for t minutes (e.g., 1 minute-10 minutes) before entering normal mode control. If the inner loop does not meet the above conditions, the frequency can be directly reduced to the upper limit of the normal frequency without dwelling.

[0140] 2. If the compressor frequency is already below the normal frequency limit when automatically or manually exiting the rage mode, the compressor frequency can be controlled normally in the normal mode.

[0141] 3. The compressor frequency reduction rate can be controlled according to different outer loop ranges. For example, if the outer loop (ambient temperature outside the target space) is below 35℃, the aforementioned X Hz / s can be 1Hz / s-5Hz / s; when the outer loop is 35℃-45℃, X Hz / s can be 1Hz / s-4Hz / s; and when the outer loop is above 45℃, X Hz / s can be 1Hz / s-3Hz / s. That is, the higher the outer loop temperature, the lower the frequency reduction rate can be.

[0142] To control the speed of the indoor fan, sudden changes in indoor capacity output can be reduced by stopping the fan. For example, a specific method could be as follows:

[0143] 1. After the compressor frequency drops to the stationary platform or the upper limit of the normal frequency, the indoor fan speed should be reduced to the maximum speed of the indoor fan in normal mode. The unit of speed can be revolutions per minute (PRM). After the compressor frequency is controlled in normal mode, it can be controlled according to the user setting. After the system is balanced, the air volume should be reduced to reduce sudden changes in indoor capacity output.

[0144] 2. If the current speed of the internal fan is lower than the target speed, it can be operated at the current speed.

[0145] To control the speed of the outdoor fan, pressure fluctuations can be reduced by stopping the outdoor fan. For example, the specific method is as follows:

[0146] After the outdoor fan maintains its current speed for a period of time t, and after the outdoor fan's open-loop control time is 1 minute to 10 minutes, if the condenser tube temperature is lower than the normal protection frequency limiting temperature T, the outdoor fan will be reduced to the normal maximum speed of the outdoor fan (RPM), and then controlled normally in the normal mode.

[0147] In this embodiment, during the exit from the rage mode, by controlling the compressor frequency, the internal fan speed and the external fan speed step by step, the air conditioning capacity output is reduced, while the indoor temperature fluctuation and air conditioning pressure change are reduced. This reduces the occurrence of sudden pressure drops in the compression chamber during the exit from the rage mode, thereby improving the stability and reliability of the air conditioning operation, reducing the damage to air conditioning components, and improving the user experience.

[0170] Those skilled in the art will also understand that the various illustrative logical blocks and steps listed in the embodiments of this application can be implemented by electronic hardware, computer software, or a combination of both. Whether such functionality is implemented through hardware or software depends on the specific application and the overall system design requirements. Those skilled in the art can implement the functionality using various methods for each specific application, but such implementation should not be construed as exceeding the scope of protection of the embodiments of this application.

[0171] This application also provides a program product including executable instructions stored in a readable storage medium. At least one processor of an electronic device can read the executable instructions from the readable storage medium, and the processor executes the executable instructions to cause the electronic device to implement the air conditioning control methods provided in the various embodiments described above.

[0172] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects in which the invention can be practiced. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” can be used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of the invention. Therefore, the following detailed description should not be considered limiting.

[0173] It should be understood that, unless otherwise specifically indicated, features of various embodiments of the invention described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0174] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," and "fixing," as used in the embodiments of the present invention, should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein according to the specific circumstances.

[0175] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0176] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0177] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0178] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements.
