Technical Field

[0002] There are multiple speed regulation modes between the main control board and the external unit board of the parking air conditioner, such as pulse frequency speed regulation, pulse width speed regulation, voltage speed regulation, etc.

[0003] However, the speed regulation method currently used has certain limitations. Specifically, the external unit board must be preset one-to-one according to the software to determine the corresponding compressor and fan frequencies before it can work normally. This method has exposed many shortcomings in actual applications. First, it lacks flexibility. Once the operating frequency of the compressor or fan needs to be adjusted, the software must be reset, which is cumbersome and time-consuming. Secondly, this method is difficult to adapt to the dynamically changing working environment and needs, and cannot achieve real-time speed regulation, which limits the performance optimization and adaptability of the parking air conditioning system.

[0063] See also Figure 1 , Figure 1It is a structural schematic diagram of an air-conditioning control system provided in one embodiment of the present application.

[0064] like Figure 1 As shown, the air conditioning control system 100 includes: a main control board 10 and at least one air conditioner 20 , and the main control board 10 is communicatively connected with the air conditioner 20 .

[0065] Among them, the main control board 10 is mainly responsible for centralized control and management of the air conditioner 20. The main control board 10 is usually composed of electronic components such as a microprocessor, a memory, and an input and output interface. The main functions of the main control board 10 include receiving instructions input by the user (such as setting temperature, wind speed, etc.), monitoring the operating status of the air conditioning control system 100 (such as indoor temperature, outdoor temperature, pressure, etc.), calculating appropriate input data according to a preset control algorithm, and sending the input data to the air conditioner 20 to achieve precise control of the air conditioner 20.

[0066] The air conditioner 20 may be a parking air conditioner or other air conditioning equipment. A parking air conditioner is an air conditioning equipment installed in a vehicle for providing cooling or heating functions. Compared with a traditional vehicle air conditioner, a parking air conditioner usually has an independent power supply system and can work when the vehicle engine is stopped to meet the comfort needs of the driver and passengers when they are resting or sleeping. A parking air conditioner usually has the characteristics of small size, light weight, easy installation, good cooling and heating effects, etc. It can obtain power through vehicle batteries, solar panels, etc., or it can work through an external power supply.

[0067] The main control board 10 and the air conditioner 20 can be connected via wired communication, such as serial communication, 485 communication, CAN (Controller Area Network) bus communication, etc. The main control board and the air conditioner can also be connected via wireless communication, such as Bluetooth communication, Wi-Fi communication, etc. In short, the communication connection method between the main control board 10 and the air conditioner 20 can be selected according to actual needs.

[0068] See also Figure 2 , Figure 2 It is a structural schematic diagram of an air conditioner provided in one embodiment of the present application.

[0069] like Figure 2 As shown, the air conditioner 20 includes: a compressor 23, an external fan 22 and a driving plate 21. The compressor 23 and the external fan 22 are connected to the driving plate 21 respectively.

[0070] The compressor 23 is the core component of the air conditioner 20. Its main function is to compress the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, providing power for the flow of the refrigerant in the entire refrigeration cycle. For example, by compressing the refrigerant, its temperature and pressure are increased, so that heat can be released in the condenser to achieve a cooling effect.

[0071] The external fan 22 is mainly used for heat dissipation and air circulation of the air conditioner 20. In the cooling mode, the external fan 22 draws outdoor air into the condenser of the air conditioner, takes away the heat released by the refrigerant in the condenser, and condenses the refrigerant into liquid. In the heating mode, the external fan 22 can also play a role in assisting heat dissipation or preventing the condenser from freezing. For example, the external fan 22 increases the heat dissipation efficiency of the condenser by speeding up the air flow, thereby ensuring the normal operation of the air conditioner.

[0072] The driving board 21 is an important control component of the air conditioner 20, which is mainly responsible for receiving input data from the main control board 10 and adjusting the compressor 23 and the outdoor fan 22 according to the input data.

[0073] See also Figure 3 , Figure 3 It is a schematic diagram of the structure of a driving board provided in one embodiment of the present application.

[0074] like Figure 3 As shown, the driving board 21 includes: at least one processor 211, and at least one memory 212, wherein the memory 212 stores a computer program, and when the program is executed by the processor 211, the processor 211 executes the steps of the air conditioning control method described below.

[0075] The processor 211 and the memory 212 may be connected via a bus or other means. Figure 3 The example of connecting through bus is taken in the following.

[0076] The processor 211 is used to provide computing and control capabilities to control the drive board 21 to perform corresponding tasks, for example, to control the drive board 21 to execute the air conditioning control method in any of the following method embodiments, including: obtaining input data; when the input data meets a preset condition, obtaining input parameters; calculating target speed regulation parameters according to the input parameters; adjusting the external fan and / or compressor according to the target speed regulation parameters so that the external fan and / or compressor works according to the target speed regulation parameters.

[0077] By first obtaining input data, basic data is provided for subsequent judgments and calculations. When the input data meets the preset conditions, input parameters are further obtained, which can accurately reflect the current power supply situation. Then, the target speed regulation parameters are calculated according to the input parameters to ensure the rationality and effectiveness of the speed regulation. Finally, the outdoor fan and / or compressor are adjusted according to the target speed regulation parameters so that they can work according to the target speed regulation parameters, thereby achieving precise control of the air-conditioning system. This method improves the stability and adaptability of the air-conditioning system, can automatically adjust the working status of the outdoor fan and compressor according to different input data conditions, improves the flexibility of air-conditioning speed regulation, provides users with a more comfortable indoor environment, and also reduces energy consumption and improves the energy efficiency ratio of the air-conditioning system.

[0078] The processor 211 may be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), a hardware chip or any combination thereof; it may also be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD) or a combination thereof. The above-mentioned PLD may be a complex programmable logic device (CPLD), a field-programmable gate array (FPGA), a generic array logic (GAL) or any combination thereof.

[0079] The memory 212 is a non-volatile computer-readable storage medium that can be used to store non-volatile software programs, non-volatile computer executable programs and modules, such as program instructions / modules corresponding to the air conditioning control method in the embodiment of the present invention. The processor 211 executes various functional applications and data processing of the driver board by running the non-volatile software programs, instructions and modules stored in the memory 32, that is, the air conditioning control method of the following method embodiment is implemented.

[0080] The memory 212 may include a volatile memory (VM), such as a random access memory (RAM); the memory 212 may also include a non-volatile memory (NVM), such as a read-only memory (ROM), a flash memory, a hard disk drive (HDD) or a solid-state drive (SSD) or other non-transitory solid-state storage device; the memory 212 may also include a combination of the above types of memory.

[0081] The memory 212 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other non-volatile solid-state storage device. In some embodiments, the memory 212 may optionally include a memory remotely arranged relative to the processor 211. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0082] One or more modules are stored in the memory 212, and when executed by one or more processors 211, the air conditioning control method in any of the following method embodiments is executed, for example, Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The steps shown.

[0083] In the embodiment of the present application, the driver board 21 may also have components such as a wired or wireless network interface, a keyboard, and an input and output interface for input and output. The driver board 21 may also include other components for realizing device functions, which will not be described in detail here.

[0084] See also Figure 4 , Figure 4 It is a structural schematic diagram of an air conditioning control method provided in one embodiment of the present application.

[0085] The air conditioning control method is applied to a driving board, and the driving board is used to control an external fan and a compressor.

[0086] like Figure 4 As shown, the air conditioning control method includes:

[0087] Step S1: Obtain input data.

[0088] The input data is a specific signal for controlling the operation of the driving board. The data input is a control signal sent from the main control board or other control devices to the driving board, such as a voltage signal, a pulse frequency signal, a pulse width signal, etc.

[0089] Specifically, the driver board receives the input data sent by the main control board. When the driver board obtains the input data, it converts it into control signals suitable for the operation of the compressor and the external fan. Different input data corresponds to different speed requirements for the compressor and the fan. For example, higher input data may cause the compressor and the fan to run at a higher speed, thereby providing stronger cooling or heating capabilities; while lower input data will cause them to run at a lower speed, reducing energy consumption and noise.

[0090] Step S2: When the input data meets the preset conditions, the input parameters are obtained.

[0091] The preset conditions are specific requirements or standards for input data that are pre-set in the air conditioning control system. These conditions are usually set to ensure that the air conditioning system can operate in a safe, stable and efficient state.

[0092] Input parameters are specific values ​​or characteristic descriptions related to input data.

[0093] Step S3: Calculate the target speed control parameters according to the input parameters.

[0094] The target speed control parameter is a specific value or index used to adjust the speed of the external fan and compressor. The target speed control parameter is determined to enable the external fan and compressor to run at the most suitable speed under different input data conditions to achieve the best cooling, heating effect and energy utilization efficiency.

[0095] Step S4: adjusting the external fan and / or the compressor according to the target speed regulation parameter, so that the external fan and / or the compressor works according to the target speed regulation parameter.

[0096] For outdoor fans, in some cases, the speed can be adjusted by changing the input data of the outdoor fan motor. The driver board determines the appropriate voltage value according to the target speed regulation parameters, and adjusts the voltage output to the outdoor fan motor through the voltage regulation circuit. Generally speaking, increasing the voltage will increase the speed of the outdoor fan, and reducing the voltage will reduce the speed.

[0097] In addition, if the external fan uses a variable frequency motor, the driver board can adjust the speed of the external fan by changing the frequency of the power output to the motor. After receiving the target speed adjustment parameters, the variable frequency controller in the driver board will adjust the frequency of the output power according to the frequency value corresponding to the target speed. For example, when the target speed adjustment parameters require the external fan to run at a higher speed, the variable frequency controller will increase the frequency of the output power to speed up the motor; conversely, reducing the frequency can slow down the speed of the external fan.

[0098] For the compressor, the driver board can control its speed by changing the power frequency output to the compressor motor, just like adjusting the external fan. The required operating frequency is determined according to the target speed regulation parameter, and then the output frequency of the inverter is adjusted. For example, when the cooling or heating capacity needs to be increased, the target speed regulation parameter will require an increase in the compressor speed, and the driver board will increase the output frequency to make the compressor run at a higher speed.

[0099] The embodiment of the present application provides an air conditioning control method, which is applied to a drive board, and the drive board is used to control an external fan and a compressor. Among them, the air conditioning control method includes: obtaining input data; when the input data meets the preset conditions, obtaining input parameters; calculating the target speed regulation parameters according to the input parameters; adjusting the external fan and / or compressor according to the target speed regulation parameters, so that the external fan and / or compressor follow the target speed regulation parameters to work. The embodiment of the present application first obtains input data to provide basic data for subsequent judgment and calculation. When the input data meets the preset conditions, further obtain input parameters, which can accurately reflect the current power supply situation. Then, the target speed regulation parameters are calculated according to the input parameters to ensure the rationality and effectiveness of the speed regulation. Finally, the external fan and / or compressor are adjusted according to the target speed regulation parameters so that they can follow the target speed regulation parameters to work, thereby realizing accurate control of the air conditioning system. This method improves the stability and adaptability of the air conditioning system, can automatically adjust the working state of the external fan and compressor according to different input data conditions, improves the flexibility of air conditioning speed regulation, provides users with a more comfortable indoor environment, and also reduces energy consumption and improves the energy efficiency ratio of the air conditioning system.

[0100] See also Figure 5 , Figure 5 It is a structural schematic diagram of an air conditioning control method provided in another embodiment of the present application.

[0101] like Figure 5 As shown, in some embodiments, before executing step S2: when the input data meets the preset condition, the step of obtaining the input parameter, the air conditioning control method further includes:

[0102] Step S6: Determine whether the input data meets the preset conditions.

[0103] The preset conditions are specific requirements or standards regarding input data that are preset in the air-conditioning control system.

[0104] The external fan, compressor and other components in the air conditioner have their specific working data range. If the input data exceeds this working data range, it may cause damage to the equipment. For example, too high input data may cause the motor winding to overheat and damage the insulation layer; too low input data may cause the motor to fail to start normally or run unstably, or even burn the motor. By pre-determining whether the input data meets the preset conditions, timely measures can be taken when the input data is abnormal, such as stopping the air conditioner operation, sounding an alarm, etc., to protect the equipment from damage.

[0105] like Figure 6 As shown, in some embodiments, determining whether the input data satisfies a preset condition includes:

[0106] Step S61: Obtain minimum speed regulation data.

[0107] The minimum speed regulation data is a preset specific voltage value. For the external fan and compressor controlled by the driver board, if the input data is less than the minimum speed regulation data, it may not start normally or cannot reach the required working state.

[0108] Step S62: When the input data is less than the minimum speed adjustment data, it is determined that the input data does not meet the preset condition.

[0109] Step S63: When the input data is greater than or equal to the minimum speed adjustment data, it is determined that the input data meets the preset condition.

[0110] By setting the minimum speed data, we can accurately judge whether the input data meets the preset conditions, so as to achieve precise control of the air conditioning system. First of all, obtaining the minimum speed data provides a clear standard for judging the input data. This minimum speed data is determined based on many factors such as the operating characteristics of the external fan and compressor controlled by the driver board and the working requirements of the electronic components. It ensures that within a certain data range, the various components of the air conditioning system can start normally and operate stably.

[0111] When the input data is less than the minimum speed data, it is determined that the input data does not meet the preset conditions. This means that the input data at this time may not provide enough power for the external fan and compressor, or may cause damage to the electronic components. In this case, the system can take corresponding measures, such as stopping operation, issuing an alarm, etc., to avoid equipment damage and system failure.

[0112] When the input data is greater than or equal to the minimum speed control data, it is determined that the input data meets the preset conditions. At this point, the system can continue with subsequent operations, obtain input parameters, calculate target speed control parameters, and adjust the operation of the external fan and compressor according to these parameters, so that they can work according to the target speed control parameters to achieve efficient and stable cooling or heating effects.

[0113] See also Figure 7 , Figure 7 It is a flowchart of a method for obtaining input parameters when input data meets preset conditions provided by an embodiment of the present application.

[0114] like Figure 7 As shown, in some embodiments, step S2: when the input data meets the preset conditions, obtaining the input parameters includes:

[0115] Step S21: Acquire maximum speed regulation data.

[0116] Among them, the maximum speed data is greater than the minimum speed data. The maximum speed data is a preset specific data. For the external fan and compressor controlled by the driver board, too high input data may also cause damage to the equipment. For example, too high input data may cause problems such as motor overheating and insulation damage. The setting of the maximum speed data can ensure that the input data is within a safe range to avoid damage to the equipment due to too high input data.

[0117] Step S22: When the input data is greater than or equal to the minimum speed adjustment data, and the input data is less than or equal to the maximum speed adjustment data, the input parameter is determined to be the input data.

[0118] Step S23: When the input data is greater than the maximum speed regulation data, the input parameter is determined to be the maximum speed regulation data.

[0119] Specifically, first, obtaining the maximum speed data provides a clear upper limit standard for judging the input data. Through this upper limit value, it can be ensured that the input data is within a reasonable range to avoid damage to the components of the air conditioning system due to excessive input data. At the same time, when the input data is greater than the maximum speed data, the input parameter is determined as the maximum speed data, which effectively limits the excessive fluctuation of the input data and protects the safe operation of the system.

[0120] Secondly, when the input data is between the minimum speed control data and the maximum speed control data, the input parameter is determined to be the actual input data. In this way, the target speed control parameter can be accurately calculated according to different input data, and the precise speed control of the external fan and compressor can be realized. This method fully considers the variation range of the input data, so that the air conditioning system can maintain efficient and stable operation under different input data conditions.

[0132] See also Figure 8 , Figure 8 It is a flowchart of a method for calculating a target speed regulation parameter based on an input voltage parameter provided in an embodiment of the present application.

[0133] In some embodiments, the above step S3: calculating the target speed regulation parameter according to the input parameter includes:

[0134] Step S31: Obtain preset speed regulation parameters.

[0135] The preset speed control parameters are a set of reference values ​​that are pre-set to calculate the target speed control parameters. When the system obtains the input parameters, the preset speed control parameters are used together with the input parameters to calculate the target speed control parameters. Users can adjust the calculation of the target speed control parameters by adjusting the preset speed control parameters, which greatly reduces the software work in the development process.

[0136] Step S32: Calculate the target speed regulation parameter according to the input parameter and the preset speed regulation parameter.

[0137] The input parameters reflect the current power supply status or the user's temperature adjustment status, which has a direct impact on the operation of the air conditioner. By combining the input parameters with the preset speed adjustment parameters, the target speed adjustment parameters that best suit the current conditions can be calculated based on the actual power supply status.

[0138] For example, if the input data is low, the system can calculate a target speed control parameter that appropriately reduces the speed of the external fan and compressor based on the preset speed control parameters and the lower input data to avoid equipment failure or unstable operation due to insufficient data.

[0139] First, when the external fan of the air conditioner is a brushless motor, the target speed regulation parameters can be calculated using the following method.

[0140] In some embodiments, the input parameters include input voltage parameters, the preset speed regulation parameters include minimum speed regulation voltage, maximum speed regulation voltage, minimum output frequency, and maximum output frequency, and the target speed regulation parameters include target speed regulation frequency.

[0141] Among them, the minimum output frequency is the lowest frequency value at which the compressor and the external fan (the external fan is a brushless motor) can operate stably. For the compressor and the brushless motor, a frequency lower than this may not be able to start normally or maintain basic working conditions. It ensures that under low load or specific working conditions, the equipment can operate at a relatively stable speed, providing the most basic cooling or heating capacity for the air-conditioning system. For example, when the air-conditioning system is in a low-load operating state, the minimum output frequency can ensure that the compressor and the brushless motor run at a low but stable speed, avoiding frequent start and stop, reducing energy consumption and extending the life of the equipment.

[0142] The maximum output frequency is the highest frequency at which the compressor and the external fan (the external fan is a brushless motor) can operate safely. When the air conditioning system needs to cool or heat quickly, or under high load conditions, the compressor and brushless motor can operate at the maximum output frequency to provide maximum cooling or heating capacity.

[0143] The target speed frequency is the expected operating frequency set for the compressor or fan based on the current operating conditions and requirements. The target speed frequency is calculated based on various parameters to achieve precise control of the air conditioning system. By adjusting the target speed frequency, the operating speed of the compressor and fan can be matched with the actual requirements, improving the efficiency and performance of the air conditioning system.

[0144] In some embodiments, the above step S32: calculating the target speed regulation parameter according to the input parameter and the preset speed regulation parameter includes:

[0145] Calculate the target speed regulation frequency according to the following formula:

[0146] FT=FL+(Ui-minDc)*10*[(FH-FL) / (maxDC*10-minDC*10)];

[0147] Among them, FT is the target speed control frequency, in Hz; FL is the minimum output frequency, in Hz; FH is the maximum output frequency, in Hz; minDC is the minimum speed control voltage, in V; maxDC is the maximum speed control voltage, in V; Ui is the input voltage parameter, in V.

[0148] For example, assuming that the minimum output frequency FL is 20Hz, the maximum output frequency FH ​​is 70Hz, the minimum speed regulation voltage minDC is 4V, the maximum speed regulation voltage maxDC is 9V, and the input voltage parameter Ui is 6.6V. Then, the target speed regulation frequency is: FT = 20 + (6.6-4) * 10 * [(70-20) / (9 * 10-4 * 10)] = 46. At this time, when the input voltage parameter is 6.6V, the target speed regulation frequency of the compressor and / or the external fan is 46Hz.

[0149] Secondly, when the external fan of the air conditioner is a brushed DC motor, the target speed regulation parameters can be calculated using the following method.

[0150] In some embodiments, the input parameters include input voltage parameters, the preset speed regulation parameters include minimum speed regulation voltage, maximum speed regulation voltage, minimum output voltage, and maximum output voltage, and the target speed regulation parameters include target speed regulation voltage.

[0151] Among them, the minimum output voltage is the lowest voltage value at which the external fan (DC brushed motor) can operate stably. If it is lower than this voltage, the motor may not start normally, or even if it starts, it may be difficult to maintain a stable working state, and it cannot meet the basic operating requirements of the air conditioning system. For example, when the power supply voltage drops to close to the minimum output voltage, the motor speed may drop significantly, resulting in poor cooling or heating effects of the air conditioner, and the air volume may also decrease.

[0152] Among them, the maximum output voltage is the highest voltage value at which the external fan (DC brushed motor) can operate safely. If this voltage is exceeded, the motor may be damaged due to overheating, insulation damage, excessive wear of mechanical parts, etc., and it may also affect the stability and safety of the entire air conditioning system. For example, if the voltage rises abnormally and exceeds the maximum output voltage, the motor may rotate too fast, generate excessive noise and vibration, and even cause motor failure or damage to other related components.

[0153] Among them, the target speed regulation voltage is the expected output voltage set for the external fan (DC brushed motor) according to the current operating conditions and requirements. It is calculated after comprehensive consideration of various parameters. By adjusting this voltage value, the motor speed can reach a specific speed that meets the operating requirements of the air-conditioning system, thereby achieving precise control of the air-conditioning cooling, heating capacity and air volume.

[0154] It should be noted that the brushed motor (external fan) of the parking air conditioner is connected with DC positive and negative poles. The higher the voltage, the faster the external fan rotates. Similarly, the lower the voltage, the lower the speed of the external fan.

[0155] In some embodiments, the above step S32: calculating the target speed regulation parameter according to the input parameter and the preset speed regulation parameter includes:

[0156] Calculate the target speed regulation voltage according to the following formula:

[0157] Uo=LDC+(Ui-minDc)*10*[(HDC-LDC) / (maxDC*10-minDC*10)];

[0158] Among them, Uo represents the target speed control voltage, in V; LDC represents the minimum output voltage, in V; HDC represents the maximum output voltage, in V; minDC represents the minimum speed control voltage, in V; maxDC represents the maximum speed control voltage, in V; Ui represents the input voltage parameter, in V.

[0159] For example, assuming that the minimum output voltage LDC is 16V, the maximum output voltage HDC is 23V, the minimum speed regulation voltage minDC is 4V, the maximum speed regulation voltage maxDC is 9V, and the input voltage parameter Ui is 7V. Then, the target speed regulation voltage is: Uo = 16 + (7-4) * 10 * [(23-16) / (9 * 10-4 * 10)] = 20.2. At this time, when the input voltage parameter is 7V, the target speed regulation voltage of the external fan (brushless DC motor) is 20.2V.

[0160] In the third aspect, when the external fan of the air conditioner is a brushless motor, the target speed control parameter can be calculated by the following method.

The above step S32: Calculating the target speed control parameter according to the input parameter and the preset speed control parameter includes:

[0161] Calculate the target speed regulation frequency according to the following formula:

[0162] FT=FL+(Fi-minF)*[(FH-FL) / (maxF-minF)];

[0163] Among them, FT is the target speed regulation frequency, in Hz; FL is the minimum output frequency, in Hz; FH is the maximum output frequency, in Hz; minF is the minimum speed regulation pulse frequency, in Hz; maxF is the maximum speed regulation pulse frequency, in Hz; Fi is the input pulse frequency parameter, in Hz.

[0164] For example, assuming that the minimum output frequency FL is 20Hz, the maximum output frequency FH ​​is 70Hz, the minimum speed regulation pulse frequency minF is 200Hz, the maximum speed regulation pulse frequency maxF is 1000Hz, and the input pulse frequency parameter Fi is 800Hz. Then, the target speed regulation frequency is: FT = 20 + (800-200) * [(70-20) / (1000-200)] = 57.5. At this time, when the input pulse frequency parameter Fi is 800Hz, the target speed regulation frequency of the compressor and / or the external fan is 57.5Hz.

[0165] In a fourth aspect, when the external fan of the air conditioner is a DC brushed motor, the target speed control parameter can be calculated by the following method. In some embodiments, the input parameter includes an input pulse frequency parameter, the preset speed control parameter includes a minimum speed control pulse frequency, a maximum speed control pulse frequency, a minimum output voltage, and a maximum output voltage, and the target speed control parameter includes a target speed control voltage. The above step S32: Calculating the target speed control parameter according to the input parameter and the preset speed control parameter includes: calculating the target speed control voltage according to the following formula:

[0166] Uo=LDC+(Fi-minF)*[(HDC-LDC) / (maxF-minF)];

[0167] Among them, Uo represents the target speed control voltage, in V; LDC represents the minimum output voltage, in V; HDC represents the maximum output voltage, in V; minF represents the minimum speed control pulse frequency, in Hz; maxF represents the maximum speed control pulse frequency, in Hz; Fi represents the input pulse frequency parameter, in Hz.

[0168] For example, assuming that the minimum output voltage LDC is 16V, the maximum output voltage HDC is 23V, the minimum speed regulation pulse frequency minF is 200Hz, the maximum speed regulation pulse frequency maxF is 1000Hz, and the input pulse frequency parameter Fi is 800Hz. Then, the target speed regulation voltage is: Uo = 16 + (800-200) * [(23-16) / (1000-200)] = 21.25. At this time, the input pulse frequency parameter Fi is 800Hz, and the target speed regulation voltage of the external fan (DC brushed motor) is 21.25V.

[0169] In a fifth aspect, when the external fan of the air conditioner is a brushless motor, the target speed regulation parameters can be calculated by the following method. In some embodiments, the input parameters include input pulse width parameters, the preset speed regulation parameters include minimum speed regulation pulse width, maximum speed regulation pulse width, minimum output frequency, and maximum output frequency, and the target speed regulation parameters include target speed regulation frequency. The above step S32: Calculating the target speed regulation parameters according to the input parameters and the preset speed regulation parameters includes: calculating the target speed regulation frequency according to the following formula:

[0170] FT=FL+(Ti-minT)*100*[(FH-FL) / (maxT*100-minT*100)];

[0171] Among them, FT is the target speed regulation frequency, in Hz; FL is the minimum output frequency, in Hz; FH is the maximum output frequency, in Hz; minT is the minimum speed regulation pulse width; maxT is the maximum speed regulation pulse width; Ti is the input pulse width parameter.

[0172] For example, assuming that the minimum output frequency FL is 20Hz, the maximum output frequency FH ​​is 70Hz, the minimum speed regulation pulse width minT is 10%, the maximum speed regulation pulse width maxT is 90%, and the input pulse width parameter Ti is 65%. Then, the target speed regulation frequency is: FT = 20 + (0.65-0.1) * 100 * [(70-20) / (0.9 * 100-0.1 * 100)] = = 54.375. At this time, the input pulse width parameter Ti is 65%, and the target speed regulation frequency of the compressor and / or the external fan is 54.375Hz.

[0173] In a sixth aspect, when the external fan of the air conditioner is a brushed DC motor, the target speed control parameter can be calculated by the following method. In some embodiments, the input parameter includes an input pulse width parameter, the preset speed control parameter includes a minimum speed control pulse width, a maximum speed control pulse width, a minimum output voltage, and a maximum output voltage, and the target speed control parameter includes a target speed control voltage. The above step S32: Calculating the target speed control parameter according to the input parameter and the preset speed control parameter includes: calculating the target speed control voltage according to the following formula:

[0174] Uo=LDC+(Ti-minT)*100*[(HDC-LDC) / (maxT*100-minT*100))];

[0175] Among them, Uo represents the target speed control voltage, in V; LDC represents the minimum output voltage, in V; HDC represents the maximum output voltage, in V; minT represents the minimum speed control pulse width; maxT represents the maximum speed control pulse width; Ti represents the input pulse width parameter.

[0176] For example, assuming that the minimum output voltage LDC is 16V, the maximum output voltage HDC is 23V, the minimum speed regulation pulse width minT is 10%, the maximum speed regulation pulse width maxT is 90%, and the input pulse width parameter Ti is 65%. Then, the target speed regulation voltage is: Uo = 16 + (0.65-0.1) * 100 * [(23-16) / (0.9 * 100-0.1 * 100)] = 20.8125. At this time, the input pulse width parameter Ti is 65%, and the target speed regulation voltage of the external fan (DC brushed motor) is 20.8125V.
