The application will be described below with reference to the attached drawings, which are used to illustrate preferred embodiments of the application:

[0036] The embodiment of the present application provides a starting control method of an air conditioner, which is applied to an air conditioner of an air conditioning system; the air conditioner can be a mobile air conditioner. The power supply mode of the air conditioner can be external power supply, for example, wireless power supply or wired power supply, the external power supply can be power supply by connecting to a power grid or power supply by connecting to a solar cell panel; and the air conditioner can also be powered by a built-in battery. A first wireless power supply module matched with the air conditioner can be provided. The first wireless power supply module can be used as a device for transmitting power of an external power source, and provides power required for working of the air conditioner; and the first wireless power supply module is used for wireless transmission, so that the air conditioner is more portable. It can be understood that the first wireless power supply module comprises a first bridge circuit and a first coil electrically connected with the first bridge circuit. It can be understood that in some scenes of charging external equipment by the air conditioner, the first wireless power supply module can also be used as a wireless power receiving end, without limitation.

[0037] Please refer to Figure 1In some examples, it can be understood that the first bridge circuit of the first wireless power transmission module 10 can include a first power device Q1, a second power device Q2, a third power device Q3 and a fourth power device Q4, the first power device Q1 and the third power device Q3 are connected in series to form a first branch, and the second power device Q2 and the fourth power device Q4 are connected in series to form a second branch; the first branch and the second branch are connected in parallel; the first end of the first coil LT is electrically connected between the first power device Q1 and the third power device Q3 through the first capacitor CT, and the second end of the first coil LT is electrically connected between the second power device Q2 and the fourth power device Q4; through the above structure, the function of the inverter circuit or the rectifier circuit can be realized.

[0038] The air conditioner 20 includes a second wireless power transmission module, which can be used to receive external power transmission, for example, can be used to receive the power output by the first wireless power transmission module 10, to realize wireless transmission of power to make the air conditioner 20 more portable. It can be understood that the second wireless power transmission module includes a second bridge circuit and a second coil Lr electrically connected with the second bridge circuit. It can be understood that in some scenarios where the air conditioner charges external devices, the second wireless power transmission module can also be used as a wireless power transmission end, without limitation.

[0039] Please continue to refer to Figure 1 In some examples, it can be understood that the second bridge circuit described above can include a fifth power device Q5, a sixth power device Q6, a seventh power device Q7 and an eighth power device Q8; the fifth power device Q5 and the seventh power device Q7 are connected in series to form a third branch, the sixth power device Q6 and the eighth power device Q8 are connected in series to form a fourth branch, and the third branch and the fourth branch are connected in parallel; the first end of the second coil Lr is electrically connected between the fifth power device Q5 and the seventh power device Q7, and the second end of the second coil Lr is electrically connected between the sixth power device Q6 and the eighth power device Q8 through the second capacitor Cr; through the above structure, the function of the rectifier or the inverter can be realized.

[0040] It can be understood that in the air conditioner 20, a compressor driving circuit IPM1, a fan driving circuit IPM2, a compressor and a fan are further included; the compressor driving circuit IPM1 and the fan driving circuit IPM2 are connected in parallel and are both electrically connected between the two ends of the second wireless power transmission module. The compressor driving circuit IPM1 is electrically connected with the compressor and is used to control the compressor; the fan driving circuit IPM2 is electrically connected with the fan and is used to control the fan. The intelligent power module can monitor the current, voltage, power and other parameters of the object it controls.

[0041] It can be understood that the air conditioner 20 can also be provided with an energy storage capacitor E1 connected across the second wireless power transmission module, which can achieve smoothing and energy storage. Through the energy storage capacitor E1, it can be determined whether there is a metal foreign object between the first coil LT and the second coil Lr.

[0042] For example, the first wireless power transmission module 10 is started to supply power to the air conditioner 20, and after the energy storage capacitor E1 stores energy, the output voltage of the first wireless power transmission module 10 is reduced to the target voltage, and the power provided by the first wireless power transmission module 10 decreases; however, due to the discharge of the energy storage capacitor E1, the bus voltage received by the air conditioner 20 is maintained at a high level, and the first wireless power transmission module 10 will not transmit power to the second wireless power transmission module for a short time; at this time, the transmission power value Pck of the first wireless power transmission module 10 is recorded. Then determine the size of the transmission power value Pck and the excitation power value Pm of the first coil LT measured in advance according to the above method (i.e. the transmission power value Pck of the first coil LT when there is no foreign object between the first coil LT and the second coil Lr). If there is a metal foreign object, the transmission power value Pck of the first wireless power transmission module 10 will be greater than the excitation power value Pm of the circuit.

[0043] It can be understood that when the air conditioner 20 has a built-in battery BT1, the built-in battery BT1 can be used to power the air conditioner 20 itself, and can also power other devices. At this time, the air conditioner 20 can also include a built-in battery BT1 and a charge-discharge voltage regulation circuit connected to the built-in battery BT1, and the compressor drive circuit IPM1 and the fan drive circuit IPM2 are also electrically connected across the charge-discharge voltage regulation circuit; After the second wireless power transmission module is energized, the remaining power for the operation of the air conditioner 20 can be used to charge the built-in battery BT1 through the charge-discharge voltage regulation circuit; The built-in battery BT1 can also supply power to each component of the air conditioner 20 through the charge-discharge voltage regulation circuit. In some examples, the charge-discharge voltage regulation circuit can include a filter capacitor E2, an inductor L1, a ninth power device Q9 and a tenth power device Q10; by controlling the on-off between the ninth power device Q9 and the tenth power device Q10, the voltage regulation is realized.

[0044] Among them, the power devices Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10 can be any one of IGBT (Insulated Gate Bipolar Transistor), MOS tube, triode, etc. transistor.

[0045] In operation, when the air conditioner 20 is powered by an external power supply, the first wireless power transmission module 10 inverts the DC bus power into high-frequency pulse power, and the first coil LT and the first capacitor CT in the circuit form a resonance under the excitation of the high-frequency pulse power and transmit the power in the form of an electromagnetic field. The second wireless power transmission module can receive the wireless power transmitted by the first wireless power transmission module 10; the second wireless power transmission module rectifies the received power into DC power to supply power to the subsequent load; the charge-discharge voltage regulation circuit can charge the power in the DC bus Psbus into the built-in battery BT1; the compressor driving circuit IPM1 drives the compressor to operate using the power in the DC bus Psbus; and the fan driving circuit IPM2 drives the fan to operate using the power in the DC bus Psbus. When the built-in battery BT1 of the air conditioner 20 is used to supply power to an external device, the alternating power output by the air conditioner 20 and received by the first wireless power transmission module 10 is rectified into DC power to supply power to the external device. The second wireless power transmission module can supply power to the first wireless power transmission module 10, the compressor driving circuit IPM1, and the fan driving circuit IPM2 in the form of voltage boosting or without voltage boosting. The second wireless power transmission module can invert the power in the DC bus Psbus into high-frequency pulse power and input the power into the first wireless power transmission module 10. It can be understood that the second coil Lr and the second capacitor Cr in the second wireless power transmission module form a resonance under the excitation of the high-frequency pulse power and transmit the power in the form of an electromagnetic field to supply power to the first wireless power transmission module 10.

[0046] Referring to Figure 2 The starting control method of the air conditioner in an embodiment of the present application comprises the following steps:

[0047] Step S10: Obtain the user-set power of the air conditioner;

[0048] Step S20: Detect the maximum power supply power for powering the air conditioner;

[0049] Step S30: Determine and start the starting component of the air conditioner in operation based on the maximum power supply power and the user-set power.

[0050] Through the steps S10 to S30, first, the user set power set by the user on the air conditioner can be received, then, the power supply of the air conditioner is detected to obtain the maximum power supply power that the air conditioner can obtain, and finally, the corresponding components of the air conditioner are started to work based on the minimum value of the maximum power supply power and the user set power, so that the air conditioner can work in the best working state to meet the user's use demand as much as possible. Moreover, the method can also be effectively applied to the case that the air conditioner has no external power supply and the built-in battery has low or insufficient power. Through the maximum power supply power detection, it is ensured that the air conditioner can use the respective components in the allowed power range in an emergency, and the utilization rate of the built-in battery and the air conditioner is improved. The specific possible implementation of each step of the method of the embodiment will be described in more detail below.

[0051] Step S10: Obtain the user set power of the air conditioner.

[0052] In step S10, the user set power is the maximum working power of the air conditioner input by the user on the panel or remote controller of the air conditioner. In the same or different application scenarios, the input value of the user set power can be different. For example, in the case of accessing to the mains, the user set power can be higher, for example, 500w, 600w, 700w, etc. In some cases without access to the mains, including but not limited to the scene without external power supply outdoors, the scene of accessing to the solar panel, etc., in order to ensure the sustainable use of the mobile air conditioner for a longer time, the user set power can be smaller, for example, 50w, 100w, 200w, 300w, etc. In some implementations, the user set power can be continuously adjustable, or can be stepwise adjustable in the form of gear positions. At the same time, it can be avoided to adjust to the critical value of starting or not starting the compressor, so as to avoid damaging the compressor.

[0053] Step S20: Detect the maximum power supply power of the air conditioner.

[0054] In step S20, the power supply of the air conditioner includes the independent power supply state of the built-in battery or the external power supply, and the common power supply state of the built-in battery and the external power supply.

[0055] It can be understood that the process of determining the maximum power supply power in the independent power supply state can be as follows: first, start the load of the air conditioner; then, control the load current to increase, and detect the change of the input voltage of the load to determine the maximum power supply power. For example, since the current and voltage values of the load can be obtained during the increase of the current of the load, the real-time power of the load can be calculated based on the power calculation formula. When the power change is detected to reach a certain value and no longer change (for example, the power of the load reaches a platform and no longer increases), it can be considered that the load reaches the maximum power. The specific ways of detecting the maximum power supply power mentioned later can be performed with reference, which is not limited.

[0056] It can be understood that in some scenarios, the air conditioner is in a built-in battery independent power supply state, and supplies power to the outside: first, the load current of the controlled load is increased, and the input voltage change of the load is detected to determine the maximum output power of the built-in battery. At this time, the power supplied by the built-in battery to the outside can be read; based on the maximum output power and the power supplied by the built-in battery to the outside, the maximum power supply power can be determined, that is, the maximum power supply power is the difference between the maximum output power and the power supplied by the built-in battery to the outside. It can be understood that the power supplied to the outside can also be controlled to be unchanged when the load current of the load is increased, and at this time the power detected by the load is the maximum power supply power available to the air conditioner.

[0057] It can be understood that when the air conditioner is in a built-in battery and external power supply hybrid power supply state; the maximum power supply power acquisition process is as follows:

[0058] First, disconnect the external power supply and connect the built-in battery, and start the load of the air conditioner; then, the load current of the controlled load is increased, and the input voltage of the load is detected to determine the maximum internal power supply power. Next, disconnect the built-in battery and connect the external power supply, and start the load of the air conditioner; control the load current of the load to increase and detect the input voltage of the load to determine the maximum external power supply power. In some examples, the maximum external power supply power is the maximum power provided by the first wireless power transmission module, or it can be the maximum power provided by the direct connection to the mains. Finally, based on the maximum internal power supply power and the maximum external power supply power, the maximum power supply power is determined. It should be noted that the order of detecting the maximum external power supply power and the maximum internal power supply power in this application scenario is not limited.

[0059] It should be noted that the compressor can be used as a load in this embodiment; for example, by using the compressor as a load for detecting power supply power, no additional circuit or device for controlling the load current needs to be set; by using an intelligent power module (IPM) as a compressor drive circuit, the load current can be continuously increased through the compressor drive circuit. Figure 1

[0060] Step S30: Based on the maximum power supply power and the user set power, determine and start the start-up component when the air conditioner is working.

[0061] ​In step S30, the control of the user-set power can ensure that the air conditioner works in the best state allowed by the current power supply, and the limitation of the user-set power can also charge the built-in battery of the air conditioner, avoiding the case that the built-in battery cannot be charged in the case that the power of the external power supply is very limited. The starting components include, but are not limited to, a fan, a control circuit related to the fan, a compressor, a control circuit related to the compressor, and a charge-discharge voltage regulation circuit of the built-in battery, etc. The possible implementation manners of step S30 will be described below.

[0062] In some implementation manners, when the air conditioner is in the state of being powered by the external power supply, the implementation process of step S30 can include the following steps:

[0063] First, the target working power of the air conditioner is determined, and the target working power is in the starting power interval of the fan of the air conditioner. Then, it is determined whether the target working power is greater than the working power of the fan. The target working power is the minimum value of the maximum power supply power and the user-set power.

[0064] It can be understood that when the user-set power is large, the air conditioner cannot reach the user-set power due to the limitation of the external power supply, for example, when the air conditioner is powered by solar energy, the air conditioner cannot reach the user-set power due to the limitation of the solar cell power supply. In order to meet the user-set power as much as possible, the air conditioner can work according to the maximum power supply power of the external power supply. The starting power interval of the fan is the power interval for supplying power to the fan to start working. The starting power interval can be pre-set and stored in the air conditioner. For example, a fan with a rated power of 50w can have a possible starting power interval of 20w-50w, 25w-50w, 30w-50w, etc. The working power of the fan is the power when the fan works normally. It can be understood that the working power can be determined by the working mode of the air conditioner or the gear of the started fan. The working power of the fan can be the rated power, or can be less than the rated power, which is not limited.

[0065] Then, if the target working power is greater than the fan working power, the fan is started and controlled to reach the fan working power. At this time, the fan can work at the fan working power, but the fan cannot completely consume the power provided by the external power supply, but the power left after the fan consumes is insufficient to start the compressor; the remaining power can be transmitted to the built-in battery for charging, realizing full utilization of the power. In some other implementations, after the energy storage reaches a certain degree, the built-in battery can output power to supplement the difference between the maximum power supply power and the user set power of the external power supply under the condition of common power supply of the external power supply and the built-in battery, so as to start the compressor to work. Through the above control, the compressor can be started in stages to achieve the refrigeration / heating effect. If the target working power is not greater than the fan working power, the fan is started to make the air conditioner reach the target working power; at this time, the air conditioner only blows air outward.

[0066] It can be understood that in some cases only the compressor needs to be started (the fan is not started), the starting control process is: determining the target working power of the air conditioner, and the target working power is located in the starting power interval of the compressor of the air conditioner, then judging whether the target working power is greater than the compressor working power of the compressor. If the target working power is greater than the compressor working power of the compressor, the compressor is started and controlled to reach the compressor working power, and the remaining power (the difference between the target working power and the compressor working power) is used to charge the built-in battery; otherwise, only the compressor is started.

[0067] In some implementations, when the air conditioner is in the state of mixed power supply of the built-in battery and the external power supply, the specific steps of step S30 can be as follows:

[0068] Determine the target working power of the air conditioner when working, and the target working power is located in the starting power interval of the compressor of the air conditioner, then start and control the fan to reach the preset fan working power; and start and control the compressor to reach the preset compressor working frequency, so that the air conditioner reaches the target working power; wherein the target working power is the minimum value of the maximum power supply power and the user set power.

[0069] It can be understood that since the target working power can meet the starting of the compressor, that is, the air conditioner can start normally. At this time, the actual working power of the fan and / or the compressor can be coordinately controlled to ensure that the total power of the air conditioner during working reaches the target working power. In some implementations, the power situation of the air conditioner during working can be calibrated through actual testing to form a power reference data; the power reference data can be a power reference table. For example, the power reference table stores the working frequency of the compressor and the corresponding total power of the air conditioner under different environmental temperatures. Therefore, based on the currently detected environmental temperature, the target working frequency of the compressor is found in the preset power reference data; the compressor is controlled to work at the target working frequency to make the air conditioner reach the target working power.

[0070] It can be understood that when the working frequency of the compressor and the working power of the fan are associated, the power reference data can include the corresponding relationship between the working frequency of the compressor, the working power of the fan and the total power of the air conditioner under different environmental temperatures. Further, under the same environmental temperature, the fan can have multiple working gears (that is, multiple fan working powers), and each working gear can correspond to the relationship between the working frequency of the compressor and the total power of the air conditioner. Therefore, the fan working power of the fan and the target working frequency of the compressor can both be obtained in the working reference data; and the air conditioner is controlled to work and make the fan reach the fan working power, and the compressor reaches the target working frequency.

[0071] Based on the power reference data to determine the fan working power of the air conditioner or the target working frequency of the compressor, the frequency of the compressor can be accurately limited; at the same time, the power matching between the compressor and the motor is more accurate, and it is ensured that the air conditioner can start and run as much as possible under the condition of power limitation.

[0072] In some implementations, when it is determined that the target working power is greater than the maximum external power supply power of the external power supply, since it is mixed power supply of the external power supply and the built-in battery at this time; the power that the external power supply is insufficient to provide can be supplemented by the built-in battery. In specific control, the output current of the built-in battery can be obtained first; then, based on the output current and the target working power, the duty cycle of the boost controller of the built-in battery is adjusted to make the external power supply reach the maximum external power supply power and the air conditioner reach the target working power. It can be understood that the power output by the built-in battery can be calculated through the output current; since the total power of the air conditioner during working is the target working power, the difference between the target working power and the maximum external power supply power is the power (denoted as the supplemented power) that needs to be supplemented by the built-in battery. At this time, the duty cycle of the boost controller can be controlled to make the output power of the built-in battery be the supplemented power, so as to make the external power supply reach the maximum external power supply power and ensure that the air conditioner can reach a longer use time in the mobile scene after the external power supply is disconnected.

[0073] In some implementations, the target working power of the air conditioner is determined based on the maximum external power supply power of the external power supply and the output power of the built-in battery. For example, the target working power of the air conditioner is determined based on the maximum external power supply power of the external power supply and the output power of the built-in battery. Figure 1For example, the boost controller is the ninth power device. When the output power of the built-in battery is greater than the make-up power, the duty cycle is increased to reduce the output power of the built-in battery; when the output power of the built-in battery is less than the make-up power, the duty cycle is reduced to increase the output power of the built-in battery. Through the control process, the air conditioner can work in the best state required by the user, while avoiding the consumption of the built-in battery, and ensuring that the air conditioner can be used when only powered by the built-in battery in other mobile scenarios.

[0074] It should be noted that in the present embodiment, if the maximum power supply power is insufficient to start any of the fan or the compressor, the air conditioner can be controlled to enter a standby state or be turned off.

[0075] Continuing with Figure 1 For example, different application scenarios of the present embodiment are described respectively:

[0076] 1. The air conditioner is in a state of being powered only by an external power source.

[0077] Please refer to Figure 3 , the controller of the air conditioner receives a start signal, at which time part of the components in the air conditioner are started. Among them, the compressor drive circuit is controlled to start the compressor as a load for detecting the power supply power; and the compressor drive circuit is controlled to continuously increase the load current of the compressor (load). The input voltage of the compressor is detected, and the relationship between the load current and the input voltage is recorded, so as to calculate the maximum power supply power of the external power source. It can be understood that when only the wireless power transmission module is powered, the power output by the second wireless power transmission module can also be detected to determine the maximum power supply power. Further, the maximum power supply power is compared with the user input power output by the user to determine the target working power. According to the target working power, it can be determined which components of the air conditioner are started. When only the fan of the air conditioner can be started, the fan is started, and the remaining power insufficient to start the compressor is charged to the built-in battery. When the compressor of the air conditioner can be started, the target working frequency of the compressor is determined through the pre-set power reference data.

[0078] For example, if the target working power is less than 10w, the air conditioner is controlled to enter standby; if the target working power is between 10w and 50w, the fan of the air conditioner is controlled to start; if the target working power is greater than 50w, the fan and the compressor of the air conditioner are controlled to start, and the working frequency of the compressor is limited based on the maximum power supply power.

[0079] 2. The air conditioner is in a state of being powered by an external power source and an internal power source.

[0080] Please refer to Figure 4, the controller of the air conditioner receives the start signal, at this time, the control accesses the power supply mode to detect the power supply of the external power supply and the built-in battery. When the built-in battery is disconnected and the external power supply is connected, the compressor drive circuit is controlled to start the compressor as a load for detecting the power supply, and the compressor drive circuit is controlled to continuously increase the load current of the compressor (load). The input voltage of the compressor is detected, and the relationship between the load current and the input voltage is recorded, so as to calculate the maximum external power supply power of the external power supply. It can be understood that when only the wireless power supply module is used for power supply, the power output by the second wireless power supply module can also be detected to determine the maximum external power supply power. When the external power supply is disconnected and the built-in battery is connected, the compressor drive circuit is controlled to start the compressor as a load for detecting the power supply, and the compressor drive circuit is controlled to continuously increase the load current of the compressor (load). The input voltage of the compressor is detected, and the relationship between the load current and the input voltage is recorded, so as to calculate the maximum internal power supply power of the built-in battery. The maximum external power supply power and the maximum internal power supply power can obtain the maximum power supply power. Further, the maximum power supply power is compared with the user input power output by the user, so as to determine the target working power. According to the target working power, it can be determined which components of the air conditioner are started. When only the fan of the air conditioner can be started, the fan is started. When the compressor of the air conditioner can be started, the target working frequency of the compressor is determined through the pre-set power reference data; wherein, the power part of the external power supply is supplemented by the built-in battery.

[0081] It should be noted that when the air conditioner is in the state of external power supply and internal power supply together, the order of detecting and obtaining the maximum internal power supply power and the maximum external power supply power is not limited.

[0082] The output power control process of the built-in battery can be seen in Figure 5 , wherein the output current of the built-in battery is detected, and the duty cycle of the ninth power device is controlled; then, it is judged whether the output power of the built-in battery is greater than the set supplement power; if the output power is greater than the supplement power, the duty cycle of the ninth power device is increased; otherwise, the duty cycle of the ninth power device is reduced.

[0083] 3、The air conditioner is in the state of built-in battery priority external power supply.

[0084] Please refer to Figure 6, the controller of the air conditioner receives the starting signal, acquires the external power supply power of the external power supply, and controls the compressor driving circuit to start the compressor as a load for detecting the power supply power; under the premise of ensuring the external power supply power, the compressor driving circuit is controlled to continuously increase the load current of the compressor (load); the input voltage of the compressor is detected, and the relationship between the load current and the input voltage is recorded, so that the maximum power supply power provided by the built-in battery to the air conditioner is calculated. Further, the air conditioner is started according to the maximum power supply power, and the starting process can refer to the above-mentioned first or second application scenarios, and will not be described here.

[0085] In the embodiment, the maximum power supply power of the power supply voltage of the air conditioner is detected, and the components started by the air conditioner are determined together with the user-set power, so that the air conditioner can reach the best working state under the premise of power supply limitation in different application scenarios, the current power supply is fully utilized, and the air conditioner is more stably worked in different power supply modes, and the refrigeration / heating effect of the air conditioner is improved.
