[0030] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0031] refer to Figure 1 , which shows a flow chart of the steps of an air conditioning control method provided by an embodiment of the present application, the method comprising:

[0032] Step 101, determining a current load parameter according to the indoor temperature of the air conditioner indoor unit and the target indoor temperature;

[0033] In the embodiment of the present application, the air conditioner indoor unit is located indoors, and the air conditioner indoor unit can output cold air or hot air to the indoor unit, thereby achieving cooling or heating, and the indoor unit temperature of the air conditioner indoor unit can be obtained by a temperature sensor arranged in the indoor unit. The target indoor temperature can be the temperature that the user wants to achieve.

[0034] The current load parameter is determined based on the indoor temperature of the air conditioner and the target indoor temperature. This can be done by performing a subtraction operation or other mathematical operations to obtain the difference between the indoor temperature and the target indoor temperature as the load parameter. The larger the difference, the farther away from achieving the target indoor temperature, and the smaller the difference, the closer the current indoor temperature is to the target indoor temperature. The load parameter can also be determined by other methods.

[0035] There is a positive correlation between the load parameter and the operating frequency of the air-conditioning compressor. The larger the load parameter, the higher the operating frequency of the air-conditioning compressor needs to be, and the smaller the load parameter, the lower the operating frequency of the air-conditioning compressor needs to be. This is because the larger the load parameter, the current indoor temperature is not close to the target indoor temperature, so the compressor needs to run at a higher operating frequency, and vice versa.

[0036] Step 102, in a preset power supply configuration, determine a target operating frequency corresponding to the current load parameter, and control the air-conditioning compressor to operate based on the target operating frequency; the preset power supply configuration includes a correspondence between multiple load parameters and operating frequencies.

[0037] In an embodiment of the present application, the preset power supply configuration includes multiple load parameters and their corresponding operating frequencies. Then, when the current load parameters are determined, the corresponding target operating frequency can be determined in the preset power supply configuration, so as to control the air-conditioning compressor to operate at the target operating frequency. Among them, the frequency of the air-conditioning compressor refers to the frequency at which the compressor operates, which can be 50 Hz-60 Hz, that is, 50-60 times per second. The target operating frequency can refer to a specific frequency value, or it can refer to a frequency interval, where each frequency interval can also be considered as a frequency gear. The interval of the compressor low-speed frequency F1 can be 10-20, so the frequency operation point can be any operating point in the interval of 10-20, and the interval of the medium and low-speed frequency F2 can be 20-40, so the frequency operation point is any operating point in 20-40, and so on.

[0038] Step 103, while the air-conditioning compressor is operating based on the target operating frequency, continuously obtaining the real-time power supply voltage of the photovoltaic device, and determining in real time a target power supply device corresponding to the power supply voltage from the candidate power supply devices; the photovoltaic device is one of the candidate power supply devices;

[0039] In an embodiment of the present application, there may be multiple candidate power supply devices for supplying power to the air-conditioning compressor, and the candidate power supply devices may include photovoltaic devices. The photovoltaic devices may be power supply devices based on photovoltaic panels, for example. The candidate power supply devices may also include other power supply devices such as batteries, etc., without limitation.

[0040] The air conditioner in this application may refer to a photovoltaic air conditioner, which refers to an air conditioner that mainly relies on photovoltaic power supply, and may also have other power supply methods, not just photovoltaic power supply. Therefore, the power supply voltage of the photovoltaic device connected to the air conditioner can be obtained first to determine the target power supply device. Different target power supply devices can be determined according to the different power supply voltages of the photovoltaic device. For example, a correspondence between a voltage range and a power supply device can be pre-constructed. When the power supply voltage of the photovoltaic device obtained falls within a specific voltage range, the corresponding power supply device can be determined.

[0041] In addition, the power supply configurations associated with different target power supply devices may be different. After determining the target power supply device, it is necessary to obtain the target power supply configuration associated with the target power supply device so that when the air-conditioning compressor is powered by the current target power supply device, the corresponding target power supply configuration can be used to accurately adjust the operating frequency of the air-conditioning compressor.

[0042] By obtaining the power supply voltage of the photovoltaic device, determining the target power supply device corresponding to the power supply voltage among the candidate power supply devices, and obtaining the target power supply configuration associated with the target power supply device, the corresponding target power supply device can be flexibly determined based on the photovoltaic power supply voltage of the photovoltaic air conditioner, and the operating frequency of the air-conditioning compressor can be controlled in a targeted manner based on the corresponding target power supply configuration, which can improve the flexibility of power supply equipment switching and the control accuracy of the compressor operating frequency.

[0043] Step 104, determining a current power supply voltage of the target power supply device during the process of the target power supply device supplying power to the air-conditioning compressor;

[0044] In an embodiment of the present application, the supply voltage of the target power supply device may change at any time. For example, if the target power supply device is a photovoltaic device, then the supply voltage of the photovoltaic device will increase or decrease with the weather changes; if the target power supply device is a battery, then as the air-conditioning compressor continues to run, the supply voltage of the battery will continue to decrease. Therefore, the current supply voltage of the target power supply device can be determined in real time during the process of the target power supply device supplying power to the air-conditioning compressor.

[0045] Step 105 , when the current power supply voltage reaches a preset update condition, adjusting the target operating frequency to obtain an updated operating frequency, and controlling the air-conditioning compressor to operate based on the updated operating frequency.

[0046] In an embodiment of the present application, different preset update conditions can be set for different target power supply devices. The preset update condition can be one or more fixed voltage values. When the preset update condition is a fixed voltage value, the target operating frequency can be adjusted when the current power supply voltage reaches the fixed voltage value. When the preset update condition is multiple fixed voltage values, the target operating frequency can be adjusted differently when the current power supply voltage reaches different fixed voltage values.

[0047] The adjustment method can be to increase the working frequency or decrease the working frequency. For example, the fixed voltage of the photovoltaic equipment may increase due to weather reasons and then reach the fixed voltage value in the preset update condition. In this case, the working frequency can be increased to make full use of the photovoltaic energy. Since the battery supply voltage is always gradually reduced during the operation of the air-conditioning compressor, the compressor operating frequency can be reduced when the battery supply voltage reaches a lower fixed voltage value in the preset update condition to slow down the power consumption rate.

[0048] In summary, in the embodiment of the present application, the current load parameter is determined according to the indoor temperature of the indoor unit of the air conditioner and the target indoor temperature. There is a positive correlation between the load parameter and the operating frequency of the air conditioner compressor. In the preset power supply configuration, the target operating frequency corresponding to the current load parameter is determined, and the air conditioner compressor is controlled to operate based on the target operating frequency. On the one hand, there is no need to set an environmental temperature sensor on the outdoor unit of the air conditioner, which can reduce the design complexity and cost of the outdoor unit of the air conditioner. The current load parameter determined based on the indoor temperature of the indoor unit of the air conditioner and the target indoor temperature can accurately describe the workload of the compressor, and then accurately determine the corresponding target operating frequency in the preset power supply configuration, thereby improving the control accuracy of the compressor frequency. On the other hand, different target power supply devices can be switched in real time based on the voltage of the photovoltaic device, and the frequency can be updated and adjusted based on the voltage of the target power supply device, thereby improving the stability of the air conditioner operation.

[0049] Since the frequency control is not based on the temperature of the external environment, the environmental temperature sensor package is cancelled, which avoids many problems caused by installing an environmental temperature sensor package on the air conditioner, such as complicated wiring of the air conditioner outdoor unit, partial space occupation, and high cost of the air conditioner outdoor unit. It can save wiring space, is conducive to the miniaturization design of the air conditioner, and saves cost.

[0050] refer to Figure 2 , which shows a flow chart of steps of another air conditioning control method provided by an embodiment of the present application, the method comprising:

[0051] Step 201, determining a current load parameter according to the indoor temperature of the air conditioner indoor unit and the target indoor temperature;

[0052] Step 202, in the preset power supply configuration, determine the target operating frequency corresponding to the current load parameter, and control the air-conditioning compressor to operate based on the target operating frequency; the preset power supply configuration includes the corresponding relationships between multiple load parameters and operating frequencies;

[0053] Step 203, during the process of the air-conditioning compressor operating based on the target operating frequency, continuously obtain the magnitude of the real-time power supply voltage of the photovoltaic device, and in the candidate power supply devices, determine the target power supply device corresponding to the magnitude of the power supply voltage in real time; the photovoltaic device is one of the candidate power supply devices;

[0054] Step 204, during the process of the target power supply device supplying power to the air-conditioning compressor, determine the current power supply voltage of the target power supply device;

[0055] Step 205, when the current power supply voltage reaches the preset update condition, adjust the target operating frequency to obtain an updated operating frequency, and control the air-conditioning compressor to operate based on the updated operating frequency.

[0056] The specific content of the above steps 201-205 can be referred to the above Figure 1 Embodiment, and will not be elaborated here.

[0057] Optionally, step 201 of determining the current load parameter according to the indoor unit temperature of the air conditioner and the target indoor temperature includes:

[0058] Sub-step 2011, determine at least one target component in the indoor unit of the air conditioner, and obtain the component temperature of each target component;

[0059] Sub-step 2012, based on the component temperature of each target component and the target indoor temperature, calculate the current load parameter.

[0060] In the embodiment of the present application, at least one target component can be determined in the indoor unit of the air conditioner. The target component can be the inner pipe, air outlet, metal-oxide-semiconductor field-effect transistor (MOSFET) in the indoor unit of the air conditioner, etc. There is no limitation on the type and quantity of the target components here.

[0061] The indoor unit temperature of the air conditioner can be jointly composed of the component temperatures of at least one target component. When the target components include the inner pipe, air outlet and MOS tube, the load parameter can be calculated by the following formula:

[0062] Ta = 丨T_inner_mos - T_set丨

[0063] Tb = 丨T_inner_pipe - T_outlet丨

[0064] T=

[0065] Among them, Tinmos represents the MOS tube temperature, Tset represents the target indoor temperature, Ta represents the first temperature difference between the MOS tube temperature and the target indoor temperature, Tintube represents the inner tube temperature, Toutwind represents the outlet temperature, Tb represents the second temperature difference between the inner tube temperature and the outlet temperature, and T is a load parameter. It can be understood that when cooling, Tintube≤Toutwind, and when heating, Tintube≥Toutwind.

[0066] Ta can reflect whether the inner loop temperature (internal temperature of the air conditioner) has met the target indoor temperature, and Tb can reflect the load of the air conditioning system. The larger the value, the normal heat exchange of the air conditioning system can effectively adjust the indoor environment. The smaller the value, the smaller the system load, and the inner loop temperature is close to the target indoor temperature. The calculated T value can help comprehensively evaluate the temperature control effect of the air conditioning system under different working conditions. A smaller T value usually indicates that the entire air conditioning system can maintain the target indoor temperature relatively accurately, while a larger T value indicates that the system parameters need to be further optimized or calibrated, and then the operating power of the compressor is adjusted to adjust the indoor temperature.

[0067] By implementing the embodiments of the present application, by selecting at least one target component in the indoor unit of the air conditioner and obtaining the temperatures of these components to jointly constitute the indoor unit temperature, the indoor unit temperature can be represented more accurately, so that the current load parameters calculated based on the component temperature of each target component and the target indoor temperature can more accurately represent the current load of the air conditioner, so that the subsequent compressor operating power control based on the load parameters can be adjusted based on more accurate data.

[0068] Optionally, before step 202 of determining a target operating frequency corresponding to the current load parameter in the preset power supply configuration and controlling the air-conditioning compressor to operate based on the target operating frequency, the method further includes:

[0069] Step A1, based on a mapping relationship between a preset load parameter and an initial operating frequency, determining a target initial operating frequency corresponding to the current load parameter, and controlling the air conditioning compressor to operate based on the target initial operating frequency;

[0070] Step A2, when the duration for which the air-conditioning compressor continues to operate based on the target initial operating frequency reaches a preset first duration, determining that the current indoor temperature has not reached the target indoor temperature.

[0071] In an embodiment of the present application, before determining the target operating frequency corresponding to the current load parameters in the preset power supply configuration to control the operating frequency of the air-conditioning compressor, an initial operating frequency can also be set for the air-conditioning compressor, and then adjusted based on the initial operating frequency.

[0072] Similarly, a mapping relationship between load parameters and initial operating frequencies may be pre-constructed to determine a target initial operating frequency corresponding to the current load parameters, and then the air conditioning compressor may be controlled to operate based on the target initial operating frequency.

[0073] In addition, the air-conditioning compressor can be controlled to work for a period of time based on the target initial operating frequency, that is, a preset first duration. After the preset first duration, it can be detected whether the current indoor temperature reaches the target indoor temperature. It is understandable that after the preset first duration, the current indoor temperature has not reached the target indoor temperature, but the temperature still changes, and the load parameters can also be updated accordingly, and then the operating frequency of the air-conditioning compressor is controlled based on the preset power supply configuration. The process of controlling the operating frequency based on the preset power supply configuration on the basis of the initial operating frequency can be understood as a correction process, and the load parameter can be understood as a temperature correction parameter. In addition, if the air-conditioning compressor continues to work based on the target initial operating frequency for the preset first duration, and the current indoor temperature reaches the target indoor temperature, no correction is required.

[0074] In implementing the embodiments of the present application, a target initial operating frequency corresponding to the current load parameter is determined through a mapping relationship between a preset load parameter and an initial operating frequency, and the air-conditioning compressor is controlled to continuously operate for a preset first period of time based on the target initial operating frequency. If the current indoor temperature does not reach the target indoor temperature after the preset first period of time, the step of adjusting based on the power supply configuration is entered. A roughly accurate initial operating frequency can be determined for the air-conditioning compressor first. If the initial operating frequency cannot meet the requirement of reaching the target indoor temperature, subsequent corrections can be continued, which can avoid the need for multiple frequency adjustments, thereby improving the efficiency of compressor frequency control.

[0075] Optionally, the candidate power supply equipment includes the photovoltaic device and a battery;

[0076] The step 203 of continuously acquiring the real-time power supply voltage of the photovoltaic device and determining in real time a target power supply device corresponding to the power supply voltage from the candidate power supply devices includes:

[0077] Sub-step 2031, continuously acquiring the real-time power supply voltage of the photovoltaic device, and comparing the power supply voltage of the photovoltaic device with a preset switching threshold;

[0078] Sub-step 2032, when the power supply voltage of the photovoltaic device is greater than or equal to the preset switching threshold, determining in real time that the photovoltaic device is a target power supply device;

[0079] Sub-step 2033, when the power supply voltage of the photovoltaic device is less than the preset switching threshold, determining in real time that the battery is the target power supply device.

[0080] In the embodiment of the present application, the candidate power supply device may include a photovoltaic device and a battery. Determining the target power supply device based on the power supply voltage of the photovoltaic device may be to compare the power supply voltage of the photovoltaic device with a preset switching threshold.

[0081] When the power supply voltage of the photovoltaic device is greater than or equal to the preset switching threshold, it means that the photovoltaic device can increase the power supply voltage sufficiently, so the photovoltaic device can be determined as the target power supply device. When the power supply voltage of the photovoltaic device is less than the preset switching threshold, it means that the power supply of the photovoltaic device is insufficient to support the normal operation of the compressor, so the battery can be determined as the target power supply device.

[0082] The preset switching threshold can be the low protection voltage of the photovoltaic device. When the power supply voltage of the photovoltaic device is lower than the low protection voltage, it means that the weather conditions are poor and the photovoltaic panel supplies less power. At this time, the compressor enters shutdown protection to prevent damage and ensure system reliability. The battery is switched to the working state, so that the battery is used as the target power supply device to meet the working voltage requirements of the air conditioner. The air conditioner switches from photovoltaic power supply to battery power supply, and the compressor starts. Similarly, if the power supply voltage of the photovoltaic device is greater than the low protection voltage or a higher voltage, it means that the weather conditions are good and the photovoltaic panel supplies more power. The photovoltaic device is switched to the working state, so that the photovoltaic device is used as the target power supply device, which can make full use of photovoltaic energy and reduce battery loss.

[0083] Optionally, when the current power supply voltage reaches a preset update condition, the step 205 of adjusting the target operating frequency to obtain an updated operating frequency, and controlling the air-conditioning compressor to operate based on the updated operating frequency includes:

[0084] When the current power supply voltage reaches the preset update condition, a frequency reduction operation is performed on the basis of the target operating frequency to obtain an updated operating frequency; the updated operating frequency is less than the target operating frequency;

[0085] The air conditioner compressor is controlled to operate based on the updated operating frequency.

[0086] In an embodiment of the present application, the preset update conditions may include some smaller voltage values. If the current supply voltage reaches a smaller voltage value in the preset update conditions, a frequency reduction operation can be performed based on the target operating frequency to obtain a smaller updated operating frequency, and then the air-conditioning compressor is controlled to operate based on the updated operating frequency.

[0087] By reducing the frequency based on the target operating frequency to obtain an updated operating frequency when the current power supply voltage reaches the preset update condition, the air-conditioning compressor is controlled to operate based on the updated operating frequency. The frequency can be reduced in time according to the voltage conditions, so that the compressor can operate based on a more appropriate updated operating frequency, thereby maintaining the stability of the compressor operation.

[0088] Optionally, when the current supply voltage reaches a preset update condition, performing a frequency reduction operation on the basis of the target operating frequency to obtain an updated operating frequency step includes:

[0089] In a case where the current power supply voltage reaches a preset update condition, determining a voltage difference between the current power supply voltage and an initial power supply voltage of the target power supply device;

[0090] Based on the target operating frequency, a frequency reduction operation is performed with an amplitude corresponding to the voltage difference to obtain an updated operating frequency.

[0091] In an embodiment of the present application, when the current power supply voltage reaches the preset update condition, the voltage difference between the current power supply voltage and the initial power supply voltage of the target power supply device can be determined. The voltage difference can indicate the magnitude of the voltage drop of the current target power supply device since power was supplied to the compressor.

[0092] Based on the target operating frequency, a frequency reduction operation is performed with an amplitude corresponding to the voltage difference to obtain an updated operating frequency. For example, the initial supply voltage is x1, and the current supply voltage after one hour of supply is x2 or x3, where x1>x2 is greater than x3, and x1 can correspond to frequency level 1. If the current supply voltage is x2, the frequency level is reduced from level 1 to level 2. If the current supply voltage is x3, the frequency level is directly reduced from level 1 to level 3.

[0093] By determining the voltage difference between the current power supply voltage and the initial power supply voltage of the target power supply device, a frequency reduction operation with an amplitude corresponding to the voltage difference is performed on the basis of the target operating frequency to obtain an updated operating frequency. Accurate frequency reduction operations can be performed according to voltage changes, so that the updated operating frequency is more in line with the current power supply voltage conditions, thereby improving the stability of the compressor operation.

[0094] Optionally, the method further includes:

[0095] In a case where the photovoltaic device is the target power supply device, determining that the power supply voltage of the photovoltaic device is greater than an over-high protection voltage of the photovoltaic device;

[0096] The power supply voltage of the photovoltaic device is distributed into a first voltage and a second voltage; the first voltage is used to supply power to the air-conditioning compressor, the first voltage is less than or equal to the over-high protection voltage, and the second voltage is used to charge the battery.

[0097] In the embodiment of the present application, since the photovoltaic device has different power generation capabilities under different weather conditions, the power supply voltage provided by the photovoltaic device fluctuates, and the power supply voltage provided by the photovoltaic device may be within a normal voltage range, or may be too low or too high. When the power supply voltage of the photovoltaic device is too high, for example, when it exceeds the set over-high protection voltage corresponding to the photovoltaic device, the air conditioning system may be damaged.

[0098] Therefore, when the photovoltaic device is the target power supply device, it is necessary to determine the power supply voltage of the photovoltaic device. When the power supply voltage is greater than the over-high protection voltage corresponding to the photovoltaic device, the power supply voltage of the photovoltaic device is distributed into a first voltage and a second voltage. The first voltage is used to supply power to the air-conditioning compressor. The first voltage is less than or equal to the over-high protection voltage, and the second voltage is used to charge the battery. The voltage detection and distribution can be achieved by adding a specific logic circuit to the circuits of the air-conditioning compressor, the power supply device, and the battery, which is not specifically limited here.

[0099] In the implementation of the embodiment of the present application, when the photovoltaic device is the target power supply device, it is determined that the power supply voltage of the photovoltaic device is greater than the over-high protection voltage of the photovoltaic device, and then the power supply voltage is allocated to a first voltage and a second voltage, which are used to supply power to the air-conditioning compressor and charge the battery, respectively. On the one hand, it can prevent the air-conditioning compressor from being subjected to a more dangerous over-high voltage, thereby improving the stability and safety of the air-conditioning compressor; on the other hand, it can store the electric energy generated by the photovoltaic device for backup, thereby improving the utilization rate of photovoltaic energy.

[0100] Optionally, the method further includes:

[0101] When the current power supply voltage does not reach the preset update condition, the air-conditioning compressor is controlled to continuously operate for a preset second time period based on the target operating frequency so that the current indoor temperature reaches the target indoor temperature.

[0102] In the embodiment of the present application, when the current power supply voltage does not reach the preset update condition, the air-conditioning compressor starts to work at the target operating frequency and continues to work for the preset second time period so that the current indoor temperature reaches the target indoor temperature. After the preset second time period, the air-conditioning compressor can be shut down. By limiting the preset second time period, the working time of the compressor can be limited to avoid excessive consumption of power and compressor performance.

[0103] It should be noted that the current power supply voltage needs to not reach the preset update condition, that is, it must always be within the corresponding voltage range, before the preset second duration can be continuously operated to ensure the stability and safety of the air conditioner operation. The voltage range corresponding to the preset update condition can be the range defined by the low protection voltage and the high protection voltage corresponding to the battery, or it can be the range defined by other voltage values, which can be adjusted according to actual needs and is not limited here.

[0104] Optionally, the method further includes:

[0105] When the air-conditioning compressor continuously operates at the target operating frequency for a period of time that reaches the preset second period of time, determining the current indoor temperature and the current supply voltage;

[0106] When the current indoor temperature does not reach the target indoor temperature and the current supply voltage does not reach a preset update condition, the air-conditioning compressor is controlled to continue to operate at the target operating frequency until the current indoor temperature reaches the target indoor temperature.

[0107] In an embodiment of the present application, when the duration of continuous operation of the air-conditioning compressor at the target operating frequency reaches a preset second duration, the current indoor temperature and the current power supply voltage can be obtained. After the compressor runs at the target operating frequency and the preset second duration, the indoor temperature will be close to the target indoor temperature. When the current indoor temperature does not reach the target indoor temperature and the current power supply voltage still does not reach the preset update condition, the air-conditioning compressor continues to be controlled to continue to work at the target operating frequency until the current indoor temperature reaches the target indoor temperature. That is, when the target indoor temperature is not reached and the power supply voltage is still sufficient and the voltage is still normal, the working time is not limited, and the compressor is controlled to continue to work at the target operating frequency until the target indoor temperature is achieved.

[0108] By implementing the embodiments of the present application, after the air-conditioning compressor has been operating at the target operating frequency for a preset second period of time and the target indoor temperature has not been achieved and the voltage is normal, the compressor can be controlled to continue operating until the target indoor temperature is achieved. Furthermore, if the power supply voltage permits, the target indoor temperature can be quickly reached without limiting the operating time, thereby improving the working efficiency of the air conditioner for temperature regulation.

[0109] Figure 3 It is a schematic diagram of the initial operating frequency and the correction process provided by the embodiment of the present application;

[0110] Step 301, air conditioning starts;

[0111] Step 302, obtaining the component temperature of each component;

[0112] Step 303, calculating a first temperature difference and a second temperature difference;

[0113] Step 304, calculating load parameters;

[0114] Step 305, detecting the power supply voltage of the photovoltaic device, comparing it with a preset switching threshold, and determining the target power supply device;

[0115] Step 306, determining a target initial operating frequency of the air conditioning compressor according to the load parameter;

[0116] Step 307, the compressor runs at the target initial operating frequency for a preset first time period to detect whether the target indoor temperature has been reached;

[0117] Step 308, if the target indoor temperature is not reached, the power supply voltage of the target power supply device is detected, compared with different set values, and the compressor operating frequency is corrected according to the comparison result;

[0118] Step 309: If the target indoor temperature has been reached, the compressor is shut down.

[0119] In the above step 308, when the target power supply device is a photovoltaic device, since the power supply voltage of the photovoltaic device is related to the weather, the power supply voltage of the photovoltaic device can be relatively stable. When the weather does not change drastically, the photovoltaic device can usually maintain a stable voltage output for a long time, and there is no need to consider the voltage change caused by power consumption. Therefore, when the target power supply device is a photovoltaic device, only the size of the load parameter can be considered when making corrections to determine the specific compressor operating frequency. Of course, if the weather changes quickly, the frequency can also be adjusted based on the changes in the parameters and the power supply voltage.

[0120] That is, in the power supply configuration corresponding to the photovoltaic device, a target operating frequency corresponding to the current load parameter is determined, and the air-conditioning compressor is controlled to operate based on the target operating frequency. Figure 4 It is a schematic diagram of the power supply process of the photovoltaic device provided in the embodiment of the present application;

[0121] Step 401, detecting the power supply voltage of the photovoltaic device;

[0122] Step 402, determine: under-protection ≤ voltage;

[0123] Step 403, if the voltage is less than the low protection level, the compressor is shut down for protection;

[0124] Step 404, switching the target power supply device to battery power supply;

[0125] Step 405, judging: voltage ≤ over-high protection;

[0126] Step 406, if the voltage is greater than the over-high protection, the compressor is shut down for protection (the voltage provided to the compressor can be reduced by distributing the voltage to charge the battery);

[0127] Step 407, determine the load parameter (T): T<T1;

[0128] Step 408, when T<T1, it means that the indoor load is very small and has approached the target indoor temperature, then the compressor is controlled to operate at (1st gear) low frequency F1 until the target indoor temperature is met and then stops.

[0129] Step 409, determine the load parameter: T<T2;

[0130] Step 410, when T1≤T<T2, it indicates that the indoor load is relatively low. In the medium-low range, the compressor can meet the temperature regulation demand with the medium-low frequency F2 (gear 2), and does not need to run at a higher frequency. The compressor is controlled to run at the frequency F2 until the target indoor temperature is met and then stops.

[0131] Step 411, determine the load parameter: T<T3;

[0132] Step 412, when T2≤T<T3, the indoor load is relatively high, in the medium-high range, the temperature adjustment demand is relatively large, and the first two operating frequencies can no longer meet the rapid cooling. The compressor is controlled to operate at the medium-high (3rd) frequency F3 until the target indoor temperature is met and then shut down.

[0133] Step 413, when T≥T3, the indoor load is very high and the demand for temperature regulation is very large. The first three operating frequencies can no longer meet the rapid cooling. The compressor is controlled to operate at the high (4th) frequency F4 until the target indoor temperature is met and then stops.

[0134] In the above example, the power supply configuration corresponding to the photovoltaic equipment includes the correspondence between different load parameter intervals and frequency gears. The different load parameter intervals are limited by T1, T2, and T3. T3 can be greater than T2, and T2 can be greater than T1. The specific values ​​of T1, T2, and T3 can be flexibly adjusted.

[0135] In step 308, when the target power supply device is a battery, since the power of the battery will decrease with use, the corresponding power supply voltage will also decrease, so it is necessary to adjust the operating frequency of the compressor based on the load parameter and the power supply voltage.

[0136] Figure 5 This is a schematic diagram of a first process of battery power supply provided in an embodiment of the present application;

[0137] Step 501, when it is determined that the load parameter T is less than T1, the indoor load is very small and has approached the target indoor temperature;

[0138] Step 502 controls the compressor to operate at a low gear (1st gear) frequency F1 for a time t1;

[0139] Step 503, determining whether the target indoor temperature has been reached;

[0140] Step 504, when the target indoor temperature is reached, the compressor stops;

[0141] Step 505, if the target indoor temperature has not been reached at this time, the power supply voltage of the battery is detected at this time;

[0142] Step 506, if under-protection ≤ voltage ≤ over-protection, the voltages are both within the normal range;

[0143] Step 507: The compressor operates at the original operating frequency until the target indoor temperature is met and then stops.

[0144] Figure 6 This is a schematic diagram of a second process of battery power supply provided in an embodiment of the present application;

[0145] Step 601, determine whether T<T2;

[0146] Step 602, when T1≤T<T2, the indoor load is low, and in the medium-low range, the compressor can meet the temperature adjustment demand with the medium-low frequency F2 (2nd gear), so the compressor is controlled to run at the frequency F2 for t2 time;

[0147] Step 603, determining whether the target indoor temperature has been reached;

[0148] Step 604, if the target indoor temperature has been reached, the compressor is shut down;

[0149] Step 605, if the target indoor temperature has not been reached at this time, the voltage of the battery is detected at this time;

[0150] Step 606, if the frequency reduction margin < voltage ≤ over-voltage protection, it means that the voltage is within the normal range and the battery power is sufficient;

[0151] Step 607, the compressor still operates at the original operating frequency, which can quickly meet the temperature adjustment requirements and improve user comfort, until the target indoor temperature is met and the compressor stops;

[0152] Step 608, determine whether the frequency reduction protection is less than the voltage and less than the frequency reduction margin; if the frequency reduction protection is less than the voltage and less than the frequency reduction margin, the power is slightly low but still within the safe range, and the compressor can continue to operate at the original operating frequency until the indoor temperature reaches the target temperature and stops;

[0153] Step 609, determine if undervoltage protection < voltage ≤ frequency reduction protection;

[0154] Step 610, if undervoltage protection < voltage ≤ frequency reduction protection, the voltage has dropped a lot and the battery power is also low. The compressor operating frequency must be downgraded to ensure power supply for air conditioning operation. The compressor operating frequency is downgraded to level 1 until the target indoor temperature is reached and the air conditioner is shut down.

[0155] Figure 7 It is a schematic diagram of a third process of battery power supply provided in an embodiment of the present application;

[0156] Step 701, determine whether T < T3;

[0157] Step 702, when T2≤T<T3, the indoor load is relatively high, in the medium-high range, and the indoor demand for cooling is relatively large. The first two operating frequencies cannot meet the temperature adjustment demand, so the compressor is controlled to operate at the medium-high (3rd) frequency F3 for t3 time;

[0158] Step 703, determining whether the target indoor temperature has been reached;

[0159] Step 704, if the target indoor temperature has been reached, the compressor is shut down;

[0160] Step 705, if the target indoor temperature has not been reached at this time, detect the voltage at this time;

[0161] Step 706, judging;

[0162] Step 707, if the frequency reduction margin is less than the voltage ≤ the over-voltage protection, the voltage is within the normal range and the power is sufficient, the compressor still runs at the original operating frequency, which can quickly meet the temperature adjustment requirements and improve the user's comfort until the target indoor temperature is met and the compressor stops;

[0163] Step 708, determining whether the frequency reduction protection is less than the voltage and less than the frequency reduction margin;

[0164] Step 709, if the frequency reduction protection < voltage ≤ frequency reduction margin, the power is slightly reduced at this time, but still within the safe range. Since the high-frequency operation has been carried out for a period of time, the indoor load has been reduced, and the compressor can be downshifted to the second gear to meet the current cooling demand until the target indoor temperature is reached and the target temperature is stopped;

[0165] Step 710, if undervoltage protection < voltage ≤ frequency reduction protection, the voltage has dropped a lot and the battery power is not sufficient. The compressor operating frequency must be downgraded to ensure that the battery can supply air conditioning operation. The compressor operating frequency is downgraded to level 2 until the target indoor temperature is reached and the air conditioner is shut down.

[0166] Figure 8 It is a schematic diagram of the fourth process of battery power supply provided in the embodiment of the present application;

[0167] Step 801, determine T <T3;

[0168] Step 802, when T≥T3, the indoor load is very high, the demand for cooling is very large, and rapid cooling is required, so the compressor is controlled to run at high-grade (4th gear) frequency F4 for time t4;

[0169] Step 803, determining whether the target indoor temperature has been reached, if the target indoor temperature has been reached, the compressor is shut down;

[0170] Step 804, if the target indoor temperature has not been reached at this time, the voltage of the battery is detected at this time;

[0171] Step 805, determining whether the frequency reduction margin is less than the voltage and less than the over-voltage protection;

[0172] Step 806, if the frequency reduction margin < voltage ≤ over-protection, the voltage is within the normal range and the power is sufficient, the compressor still runs at the original operating frequency, which can quickly meet the indoor cooling capacity demand and improve user comfort until the target indoor temperature is met and the target temperature is reached and the compressor stops;

[0173] Step 807, determining whether the frequency reduction protection is less than the voltage and less than the frequency reduction margin;

[0174] Step 808, if the frequency reduction protection < voltage ≤ frequency reduction margin, the power is slightly reduced, but still within the safe range. However, the long-term high-frequency operation of the compressor will lead to insufficient battery power, which will cause voltage instability and damage the battery. Since the high-frequency operation has been carried out for a period of time, the indoor load is greatly reduced, so the compressor frequency can be downgraded to the third gear to meet the current cooling demand until the target indoor temperature is reached and the target temperature is shut down;

[0175] Step 809, determine if undervoltage protection < voltage ≤ frequency reduction protection;

[0176] Step 810, if undervoltage protection < voltage ≤ frequency reduction protection, the power has dropped significantly at this time, and the compressor operating frequency must be downgraded to ensure that the battery supplies air conditioning operation. The compressor frequency is downgraded to gear 2 and operates until the target indoor temperature is reached and the target temperature is shut down.

[0177] In the above example, the power supply configuration corresponding to the battery includes the correspondence between different load parameter intervals and frequency gears. The different load parameter intervals are limited by T1, T2, and T3. The specific values ​​of T1, T2, and T3 can be flexibly adjusted, and the battery's frequency reduction protection voltage, frequency reduction margin voltage, over-high protection voltage, and under-low protection voltage can all be set as needed.
