Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a method, device, and air conditioning equipment for controlling an outdoor fan of an air conditioner. Background Technology

[0002] As a core tool for regulating temperature, the performance of air conditioners directly affects the user's comfort experience, especially during hot seasons or in enclosed spaces, where users have a particularly urgent need for the cooling capacity of air conditioners.

[0003] In related technologies, the speed adjustment of the outdoor fan of an air conditioner is usually based on the current operating mode or environmental parameters (such as indoor / outdoor temperature). For example, in normal mode, the outdoor fan runs at the lowest speed to save energy, and the speed is gradually increased only when an increase in the condenser's heat dissipation demand is detected.

[0004] However, when an air conditioner needs to increase the compressor frequency and cooling output in a short period of time, the adjustment of the outdoor fan speed often lags behind the changes in system load, resulting in insufficient heat dissipation capacity of the condenser, which in turn leads to problems such as compressor overload and excessively high exhaust temperature. Summary of the Invention

[0005] This invention provides a method, device, and air conditioning equipment for controlling an air conditioner's outdoor fan. It can adjust the speed of the air conditioner's outdoor fan in advance before increasing the frequency of the air conditioner compressor, thereby helping to improve the heat dissipation capacity of the condenser.

For example, "first duration" and "first duration" are merely used to distinguish different durations and do not limit their order. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or execution order, and that terms such as "first" and "second" do not necessarily imply that they are different.

[0048] It should be noted that in the embodiments of the present invention, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in the present invention should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone, where A and B can be singular or plural.

[0050] For example, refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of an air conditioner provided in an embodiment of the present invention.

[0051] In some implementations, the air conditioner 100 includes an indoor unit 110 and an outdoor unit 120.

[0052] Optionally, the indoor unit 110 includes an indoor controller 111 and an indoor fan 112.

[0053] The indoor controller 111 is used to receive control commands from users. For example, users can send control commands such as air conditioner temperature, fan speed, and mode to the indoor controller 111 via buttons or displays on the control panel.

[0054] The indoor fan 112 is used to draw indoor air into the indoor unit of the air conditioner, cool or heat it through the evaporator, and then blow it back into the room to achieve indoor air circulation.

[0055] Optionally, the outdoor unit 120 includes a compressor 121, an outdoor fan 122, and an outdoor controller 123.

[0056] The outdoor controller 123 can be used to control the compressor 121 according to the user control command received by the indoor controller 111, so as to adjust the compressor speed.

[0057] In addition, the outdoor controller 123 can also be used to obtain the current speed of the compressor 121, calculate the target speed of the outdoor fan 122 based on the current speed of the compressor 121, and control the outdoor fan 122 based on the target speed of the outdoor fan 122 so that the speed of the outdoor fan 122 matches the speed of the compressor 121.

[0058] For example, a user can control the air conditioner 100 to turn on via a remote control, control panel, etc., and set the operating parameters of the air conditioner 100, including the working mode, target temperature, and fan speed of the indoor fan 122. After receiving the operating parameters set by the user, the indoor controller 111 starts the indoor fan 122 and simultaneously sends the operating parameters of the air conditioner 100 to the outdoor controller 123.

[0059] After receiving the operating parameters sent by the indoor controller 111, the outdoor controller 123 starts the compressor 121, the outdoor fan 122, and the outdoor controller 123 itself. The outdoor controller 123 adjusts the speed of the compressor 121 according to the aforementioned operating parameters. Simultaneously, the outdoor controller 123 acquires the current speed of the compressor 121 in real time and calculates the optimal speed of the outdoor fan 122 (the optimal energy-efficient fan speed, at which the air conditioner's energy efficiency is maximized) based on the current speed of the compressor 121. Then, it controls the outdoor fan 122 according to the optimal speed, enabling the outdoor fan 122 to quickly and accurately reach the optimal speed.

[0060] When the indoor temperature reaches the target temperature set by the user, the outdoor controller 123 adjusts the speed of the compressor 121. At the same time, based on the current speed of the compressor 121, it calculates the optimal speed of the outdoor fan 122 and controls the outdoor fan 122 according to the optimal speed. This cycle continues until the indoor temperature is stabilized at the target temperature.

[0061] During the entire operation of the air conditioner 100, the outdoor controller 123 adjusts the speed of the compressor 121 according to the user's needs, calculates the optimal speed of the outdoor fan 122 based on the real-time detected speed of the compressor 121, and controls the outdoor fan 122 according to the optimal speed, thereby realizing the joint control of the compressor 121 and the outdoor fan 122.

[0062] In modern homes and offices, air conditioning is a core tool for regulating indoor temperature, and its performance directly impacts user comfort. This is especially true during hot seasons or in enclosed spaces, where users have a greater need for cooling capacity.

[0063] For example, in extreme weather conditions, such as scorching heat or freezing cold, it is necessary to quickly lower or raise the indoor temperature; or, when users have just returned home, they want to quickly enjoy a comfortable indoor environment; or, when there are many people indoors, it is necessary to quickly adjust the indoor temperature to meet the needs of multiple people.

[0064] In order to achieve rapid cooling or heating in hot seasons or enclosed spaces, some air conditioners have a "rampage mode" function. When this mode is turned on, the air conditioner's compressor will run at a speed exceeding its original rated speed, thereby rapidly lowering or raising the indoor temperature in a short period of time.

[0065] Optionally, the above-mentioned "Rage Mode" may also be called "Power Mode", "Super Mode" or "Extreme Speed ​​Mode", etc., and no limitation is made in this embodiment of the invention.

[0066] In related technologies, when a user triggers the "frenzy mode" of an air conditioner, the air conditioner needs to output maximum cooling capacity in a very short time to quickly reduce the indoor temperature. However, this high-load operation mode is often accompanied by a sharp increase in system pressure, high and low pressure difference, and instantaneous current, which causes key components such as the compressor and outdoor fan to be subjected to greater mechanical and electrical stress, posing potential reliability risks, such as compressor overload and reduced condenser heat dissipation efficiency.

[0067] Existing air conditioning control logic typically adjusts the speed of the outdoor fan only when the user actively triggers the "tyranny mode," lacking a mechanism to predict potential high load demands. This results in the inability to improve heat dissipation capacity in advance, and the delayed response time of the "tyranny mode" makes it difficult to meet the user's immediate need for rapid cooling.

[0068] For example, in existing air conditioning control technology, the speed adjustment of the outdoor fan is usually based on the current operating mode or environmental parameters (such as indoor / outdoor temperature, pressure sensor feedback, etc.) and responds in real time. In normal mode, the outdoor fan operates at the lowest speed to save energy, and the speed of the outdoor fan is gradually increased only when an increase in the condenser's heat dissipation demand is detected.

[0069] However, when users switch to "violent mode", the air conditioner needs to increase the compressor frequency and increase the cooling output in a short period of time. At this time, the adjustment of the outdoor fan speed often lags behind the changes in system load, resulting in insufficient heat dissipation capacity of the condenser, which in turn causes problems such as compressor overload and excessively high exhaust temperature.

[0070] Furthermore, the relevant technologies do not include predictive control based on user behavior (such as the frequency of use of "Rage Mode" and the duration of high-frequency operation), resulting in the cooling system always being in a passive response state when the user triggers "Rage Mode", making it difficult to improve cooling capacity in advance.

[0071] Therefore, how to dynamically adjust the speed of the outdoor fan before the "frenzy mode" is activated, thereby improving the air conditioner's heat dissipation capacity, has become a pressing technical problem that needs to be solved.

[0072] To address the aforementioned technical problems, this invention provides an air conditioner outdoor fan control method. By dynamically identifying user behavior and air conditioner operating status, it can predict high-load demand scenarios in advance and proactively adjust the minimum speed of the outdoor fan before the "frenzy mode" is activated, thereby improving heat dissipation capacity in advance.

[0073] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0074] Reference Figure 2 , Figure 2 This is a flowchart illustrating an air conditioner outdoor fan control method provided in an embodiment of the present invention.

[0075] In some embodiments, the above-mentioned air conditioner outdoor fan control method includes:

[0076] S201, Collect the first data.

[0077] Optionally, the first data includes at least one of the following:

[0078] (1) User behavior data

[0079] In some implementations, user behavior data can be generated based on user actions. For example, it can be generated based on user mode selection actions (high-power mode, energy-saving mode, silent mode, etc.), temperature setting actions, fan speed selection actions, and on / off actions.

[0080] In some implementations, user behavior data may also include behavioral characteristics generated by the user during the use of the air conditioner, including but not limited to the duration of use of the first working mode, the frequency of use of the first working mode, and the time period of use of the first working mode.

[0081] (2) Historical operating data of air conditioners

[0082] In some implementations, the historical operating data of the air conditioner may include data collected during the past period of operation of the air conditioner, including but not limited to compressor frequency, frequency increase times, etc.

[0083] Alternatively, historical operating data for air conditioners can include data collected during the last operation of the air conditioner.

[0084] (3) Ambient temperature data

[0085] In some implementations, the aforementioned ambient temperature data may include real-time outdoor temperature, outdoor temperature change data over a future period, weather forecast data, etc.

[0086] S202. Based on the first data, determine whether the conditions for entering the first working mode are met. If yes, continue to execute S203; if no, return to execute S201.

[0087] The first working mode is the working mode in which the air conditioner compressor operates at a frequency greater than a first frequency threshold, where the first frequency threshold is the maximum frequency at which the compressor operates in other working modes besides the first working mode.

[0088] Optionally, the first working mode described above may also be called "frenzy mode", "powerful mode", "super strong mode" or "high-speed operation mode", etc., and no limitation is made in this embodiment of the invention.

[0089] Among these, the other operating modes can be those that meet noise requirements. For example, other operating modes may include gentle breeze mode, normal cooling / heating mode, and the highest fan speed setting. When the air conditioning unit is in any of these other operating modes, the noise generated by the air conditioning unit must be less than the preset noise level.

[0090] For example, the indoor unit of an air conditioner is preset to 42 decibels and the outdoor unit is preset to 52 decibels. When the air conditioner is turned on in other operating modes, the compressor and indoor and outdoor fans will generate noise, but the operating noise of the indoor and outdoor units will still be within the preset noise range of the indoor unit and the outdoor unit, respectively.

[0091] Among them, the indoor unit preset noise and the outdoor unit preset noise can refer to the indoor unit noise value and the outdoor unit noise value marked on the nameplate of the air conditioning equipment in accordance with the national standard testing standards.

[0092] In some embodiments, when the compressor's operating frequency is greater than a first frequency threshold, it indicates that the present invention addresses a first operating mode of the air conditioning device. Specifically, the first frequency threshold 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 conditioning device in other operating 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.

[0093] For example, assuming that the maximum frequency of the air conditioner's compressor when operating in other working modes is 120Hz, then the first working mode is the working mode in which the air conditioner's compressor operates at a frequency greater than 120Hz.

[0094] Understandably, the compressor's operating frequency exceeding the first frequency threshold is a core characteristic of the aforementioned first operating mode. This is because the primary requirement of the first operating mode is to rapidly reduce the temperature difference between indoors and outdoors. Therefore, it needs to overcome the frequency limitations of the normal mode, allowing the compressor to operate at a higher frequency to maximize cooling / heating capacity. In other words, the first operating mode can overcome noise limitations to achieve maximum cooling or heating effect. 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, high efficiency, and operational safety, precisely matching the usage scenarios of the first operating mode.

[0095] For example, suppose that in operating modes other than the first operating mode, the highest operating frequency of the compressor at maximum load is n1, and in the first operating mode, the compressor operating frequency is n2. Then, under the same operating conditions, n2>n1.

[0096] Where n1 is less than the upper limit of the frequency indicated on the compressor nameplate, and n2 is less than or equal to the upper limit of the frequency indicated on the compressor nameplate. For example, in operating modes other than the first operating mode, taking a certain model of air conditioner as an example, in cooling mode, n1 is 80Hz-90Hz, and in heating mode, n1 is 100Hz-110Hz. In the first operating mode, in cooling mode, n2 is 91Hz-140Hz, and in heating mode, n2 is 111Hz-140Hz.

[0097] Taking a 1.5 horsepower air conditioner as an example, in all operating modes except the first operating 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 the first operating mode, the compressor is allowed to operate at a frequency exceeding 108 Hz, but less than or equal to 140 Hz. That is, in the first operating mode, the compressor's maximum operating frequency can reach 100% of the upper limit of the compressor nameplate frequency.

[0098] The first operating mode can overcome the limitations of other operating modes, with at least one of the operating frequency and fan speed exceeding the preset value, or both. However, compared to other operating modes, it is closer to the hardware limits of the compressor and fan. Prolonged operation may cause the temperature of electrical components and control systems to exceed the limits. Therefore, within the design margin, the first operating mode can be allowed to run for 5 to 60 minutes before exiting. The running time of the first operating mode can be set by the user or left as a default value.

[0099] In some implementations, the air conditioner may be predicted to enter a first working mode based on the first data. If the first data meets the conditions for entering the first working mode, it can be assumed that the air conditioner will enter the first working mode in the future.

[0100] S203. Adjust the speed of the outdoor fan of the air conditioner.

[0101] In some implementations, when it is determined that the air conditioner meets the conditions for entering the first operating mode, the speed of the air conditioner's outdoor fan can be actively adjusted to improve the heat dissipation capacity of the condenser in advance.

[0102] In some implementations, the current speed of the external fan can be adjusted to a target value, wherein the target value is greater than the current speed of the external fan and less than or equal to the maximum speed of the external fan.

[0103] In some implementations, when the air conditioning equipment enters the first working mode, the speed of the outdoor fan of the air conditioning equipment can be adjusted to a preset speed, which is the maximum speed at which the outdoor fan operates in other working modes besides the first working mode.

[0104] For example, assuming the current speed of the outdoor fan is 300 rpm, when it is determined that the air conditioner meets the conditions for entering the first working mode, the current speed of the outdoor fan can be increased from 300 rpm to 400 rpm to improve the heat dissipation capacity of the condenser in advance.

[0105] The air conditioner outdoor fan control method provided in this embodiment of the invention can identify potential user needs in advance by analyzing user behavior data, air conditioner historical operation data, ambient temperature data, etc., and dynamically adjust the minimum speed of the outdoor fan before increasing the air conditioner power. This adjustment can enable the condenser to have higher heat dissipation capacity before increasing the air conditioner power, thereby avoiding compressor overload, excessively high exhaust temperature, and other situations caused by insufficient heat dissipation capacity.

[0106] In some embodiments, the first data mentioned above includes user behavior data, which includes a start command for a first working mode.

[0107] In some implementations, the aforementioned user behavior data may also include user historical usage data.

[0108] In some implementations, the air conditioner can be determined to meet the conditions for entering the first operating mode when the aforementioned first data satisfies any one of the following conditions:

[0109] (1) The start command of the first working mode is detected.

[0110] For example, when the user triggers the start command for the first working mode, it is determined that the air conditioner meets the conditions for entering the first working mode. Thus, when the air conditioner just enters or is about to enter the first working mode, the minimum speed of the outdoor fan can be increased immediately, so that the air conditioner has a more efficient heat dissipation capacity before entering the first working mode.

[0111] (2) The current time is within the predicted time period when the air conditioner enters the first working mode.

[0112] In some implementations, the time period during which the air conditioner will enter the first operating mode can be predicted based on the aforementioned historical user data; within this time period, it can be determined that the air conditioner meets the conditions for entering the first operating mode.

[0113] For example, historical user data of the air conditioner over a period of time (such as the past week or the past month) can be collected, including the time each time the first working mode is entered; based on the collected historical user data, the time period during which the air conditioner will enter the first working mode can be predicted.

[0114] For example, assuming that a user has been using the first working mode every day from 3 pm to 4 pm for the past week, it can be predicted that the air conditioner will enter the first working mode during the period from 3 pm to 4 pm.

[0115] The air conditioner outdoor fan control method provided in this embodiment of the invention can predict whether the air conditioner will enter the first working mode based on user behavior data. Therefore, the minimum speed of the outdoor fan can be adjusted in advance before the air conditioner enters or is about to enter the first working mode, so that the air conditioner has a more efficient heat dissipation capacity before entering the first working mode.

[0116] In some embodiments, the first data mentioned above includes historical air conditioner operating data, which includes at least one of the following:

[0117] The duration of the first working mode of the air conditioner in the most recent operating period, the cumulative duration of the air conditioner operating at a frequency greater than the first frequency threshold in the most recent operating period, and the number of times the air conditioner operating at a frequency greater than the first frequency threshold in the most recent operating period.

[0118] Optionally, the conditions for entering the first operating mode are determined to be met when any of the above-mentioned historical air conditioner operating data meets one of the following criteria:

[0119] (1) The first duration is greater than or equal to the first duration threshold.

[0120] Optionally, the first duration threshold can be determined based on the duration during which the air conditioner has entered other operating modes within a recent period of operation.

[0121] For example, the first duration threshold can be the duration during which the air conditioner enters normal operating mode within a recent period of operation.

[0122] When the first duration is greater than or equal to the first duration threshold, it means that the probability of the air conditioner entering the first working mode is greater than the probability of entering other working modes during the most recent operating period. Therefore, it can be determined that the probability of the air conditioner entering the first working mode when it is started next time is relatively high, thus satisfying the condition of entering the first working mode.

[0123] (2) The cumulative duration mentioned above is greater than or equal to the second duration threshold.

[0124] Among them, if the cumulative duration of the air conditioner's operating frequency being greater than or equal to the preset frequency threshold within the recent operating period is greater than or equal to the second duration threshold, it indicates that the air conditioner is in a high-load operating state within the recent operating period. Therefore, it can also be determined that the air conditioner is more likely to enter the first working mode when it is started next time, thus meeting the conditions for entering the first working mode.

[0125] (3) The above number of times is greater than or equal to the threshold of the first number.

[0126] If the number of times the air conditioner operates at a frequency greater than or equal to the preset frequency threshold within a recent operating period is greater than or equal to the first threshold, it indicates that the air conditioner has been frequently operating under high load within a recent operating period. Therefore, it can be determined that the air conditioner is more likely to enter the first working mode when it is started next time, thus meeting the conditions for entering the first working mode.

[0127] For example, the aforementioned historical operating data of the air conditioner includes at least one of the following:

[0128] The duration of the first working mode when the air conditioner was last used, the cumulative duration of the air conditioner's operating frequency being greater than the first frequency threshold when it was last used, and the number of times the air conditioner's operating frequency was greater than the first frequency threshold when it was last used.

[0129] The condition for entering the first operating mode is determined when any one of the following conditions is met based on the above-mentioned historical air conditioner operating data:

[0130] The duration of the first working mode when the air conditioner was last used was greater than the duration of other working modes; the cumulative duration of the air conditioner's operating frequency being greater than the first frequency threshold when it was last used was greater than or equal to the second duration threshold (e.g., 30 minutes); the number of times the air conditioner's operating frequency was greater than the first frequency threshold within the preset duration (e.g., 30 minutes) when it was last used was greater than or equal to the first number threshold (e.g., 3 times).

[0131] In this embodiment of the invention, by comprehensively analyzing user behavior patterns (such as the frequency of use of the rage mode) and system operating status (such as the number of frequency increases), potential high load demands are identified in advance, and the minimum speed of the external fan is dynamically increased before the rage mode is activated, thereby shortening the response time of the rage mode and improving the heat dissipation capacity.

[0132] The air conditioner outdoor fan control method provided in this embodiment of the invention predicts whether the air conditioner will enter the first working mode based on the air conditioner's historical operating data. Therefore, the minimum speed of the outdoor fan can be increased in advance before the air conditioner enters the first working mode, so that the air conditioner has a more efficient heat dissipation capacity before entering the first working mode.

[0133] In some embodiments, the first data includes ambient temperature data; determining whether the conditions for entering the first operating mode are met based on the first data includes:

[0134] Based on ambient temperature data, determine whether the outside temperature is greater than a preset temperature threshold; or, based on ambient temperature data, predict whether the outside temperature will be greater than a preset temperature threshold within a second time period; if the outside temperature is greater than the preset temperature threshold, or if the outside temperature is greater than the preset temperature threshold within the aforementioned second time period, determine that the conditions for entering the first working mode are met.

[0135] Optionally, the aforementioned preset temperature threshold can be pre-configured by the air conditioner or can be customized by the user according to their own needs.

[0136] Optionally, the range of the preset temperature threshold can be 35℃~45℃.

[0137] It is understandable that when the outside temperature is greater than the preset temperature threshold (such as 40℃), it means that it is hot weather, so it can be determined that the air conditioner meets the conditions to enter the first working mode.

[0138] For example, based on ambient temperature data (such as weather forecast), it can be determined whether the outside temperature will be greater than a preset temperature threshold (such as 40°C) in the next 1 to 2 hours. If the outside temperature is greater than the preset temperature threshold (such as 40°C) in the next 1 to 2 hours, it can also be determined that the air conditioner meets the conditions for entering the first working mode.

[0139] The air conditioner outdoor fan control method provided in this embodiment of the invention predicts whether the air conditioner will enter the first working mode based on ambient temperature data. Therefore, the minimum speed of the outdoor fan can be adjusted in advance before the air conditioner enters the first working mode, so that the air conditioner has a more efficient heat dissipation capacity before entering the first working mode.

[0140] In some embodiments, user behavior data, historical air conditioner operation data, and ambient temperature data can be combined to determine whether the air conditioner meets the conditions for entering the first operating mode.

[0141] For example, when user behavior data and / or historical air conditioner operation data indicate that the air conditioner meets the conditions for entering the first operating mode, the speed of the outdoor fan is increased in advance, so that the condenser has a higher heat dissipation capacity before entering the first operating mode. By increasing the speed of the outdoor fan in advance, the risk of compressor overload due to insufficient heat dissipation can be avoided, and the waiting time for users to receive cooling output can also be reduced.

[0142] In some embodiments, a human infrared sensor can be used to detect the number of people and activity areas indoors to determine whether the air conditioner meets the conditions for entering the first working mode.

[0143] For example, when the number of people indoors is greater than a preset threshold and the activity area is smaller than a specified threshold, it can be determined that the air conditioner meets the conditions for entering the first working mode.

[0144] In some embodiments, weather forecasts can also be used to determine whether the air conditioner meets the conditions for entering the first operating mode.

[0145] For example, when a high temperature warning is received, it can be determined that the air conditioner meets the conditions for entering the first working mode.

[0146] The air conditioner outdoor fan control method provided in this embodiment of the invention can determine whether the air conditioner meets the conditions for entering the first working mode based on the number of people indoors or the weather forecast, thereby achieving accurate prediction of high load demand.
