[0058] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0059] To facilitate the understanding of the embodiments of the present application, further explanation and description will be made in connection with specific embodiments by referring to the drawings. The embodiments do not constitute a limitation on the embodiments of the present application.

[0060] Reference Figure 1 , Figure 1 A flowchart of a control method of an air conditioning system provided by an embodiment of the present application is shown in the figure. The control method of an air conditioning system provided by an embodiment of the present application is applied to an air conditioning system. The air conditioning system includes multiple outdoor units. The air conditioning system can be a photovoltaic air conditioning system, and can also be a hybrid air conditioning system. The photovoltaic air conditioning system specifically refers to that the multiple outdoor units in the photovoltaic air conditioning system are photovoltaic outdoor units. The hybrid air conditioning system specifically refers to that the multiple outdoor units in the hybrid air conditioning system include both photovoltaic outdoor units and non-photovoltaic outdoor units.

[0061] The control method of the air conditioning system includes the following steps:

[0062] S101: When it is determined that a first outdoor unit in a running state fails in the multiple outdoor units, determining fault information corresponding to the first outdoor unit and type information corresponding to the first outdoor unit.

[0063] In the embodiment, the execution subject is a controller in the air conditioning system. The fault information includes a power generation module fault in the first outdoor unit, a non-power generation module fault in the first outdoor unit, and any module fault in the first outdoor unit. The type information includes photovoltaic type and non-photovoltaic type.

[0064] S102: Determine the control strategy corresponding to the first outdoor unit according to the fault information and the type information.

[0065] In this embodiment, after determining the fault information and the type information, the controller pre-stores a control algorithm, and logically judges the fault information and the type information through the control algorithm to determine the control strategy corresponding to the first outdoor unit. When the air conditioning system is a photovoltaic air conditioning system, when it is determined that the type information is photovoltaic type, different control strategies are determined according to the fault information, which is the fault of the power generation module in the first outdoor unit and the fault of the non-power generation module in the first outdoor unit. When the air conditioning system is a hybrid air conditioning system, when it is determined that the type information is photovoltaic type, different control strategies are determined according to the fault information, which is the fault of the power generation module in the first outdoor unit and the fault of the non-power generation module in the first outdoor unit, and when it is determined that the type information is non-photovoltaic type, the control strategy corresponding to the fault information of any module in the first outdoor unit is determined. The specific determination form of the control strategy will be described below, which will not be described here in this embodiment.

[0066] S103: Control the plurality of outdoor units according to the control strategy.

[0067] In this embodiment, the control strategy includes the operation strategy and the switching strategy corresponding to the first outdoor unit, and the plurality of outdoor units are controlled according to the operation strategy and the switching strategy. The operation strategy specifically refers to the operation mode of the first outdoor unit, and the switching strategy specifically refers to the switching mode of the first outdoor unit.

[0068] The control method of the air conditioning system provided in this embodiment does not need to directly control the first outdoor unit to stop running when the first outdoor unit with fault exists in the air conditioning system, but different control strategies are executed on the plurality of outdoor units through the fault information and the type information of the first outdoor unit, which improves the user experience and maximizes the benefits during the fault of the first outdoor unit.

[0069] Reference Figure 2 , Figure 2 This is another flowchart of the control method of the air conditioning system provided in this embodiment. The control method of the air conditioning system provided in this embodiment is applied to a photovoltaic air conditioning system. The control method of the air conditioning system includes the following steps:

[0070] S201: When it is determined that the first outdoor unit with fault exists in the plurality of outdoor units in the running state, determine the fault information corresponding to the first outdoor unit and the type information corresponding to the first outdoor unit, and the type information is photovoltaic type.

[0071] In this embodiment, the S201 step is consistent with the above S101 step, which will not be described here in this embodiment, and the specific description can be referred to the above S101 step.

[0072] S202: Determine whether the fault information is a non-power generation module fault in the first outdoor unit.

[0073] In this embodiment, the first outdoor unit is a photovoltaic type outdoor unit, and the photovoltaic type outdoor unit is provided with a power generation module, an inverter module and an energy storage module. The fault of the power generation module and the non-power generation module in the photovoltaic type outdoor unit is determined to determine whether the photovoltaic air conditioner can receive light energy.

[0074] S203: When the fault information is a non-power generation module fault in the first outdoor unit, determine a second outdoor unit in a shutdown state from the plurality of outdoor units.

[0075] In this embodiment, when the non-power generation module in the first outdoor unit fails, it indicates that the power generation module in the photovoltaic type outdoor unit can receive light energy, and the received light energy can be converted into electrical energy by the inverter module for use to maximize the benefits during the failure of the first outdoor unit. And determine whether there is a second outdoor unit in a shutdown state in the plurality of outdoor units to determine whether the first outdoor unit meets the switching condition. When there is a second outdoor unit in a shutdown state in the plurality of outdoor units, it is determined that the first outdoor unit meets the switching condition, and after it is determined that the first outdoor unit meets the switching condition, the step S206 is executed. When there is no second outdoor unit in a shutdown state in the plurality of outdoor units, it indicates that there is no second outdoor unit that can be switched in the air conditioning system. At this time, in order to ensure the reliability of the entire control system, the entire air conditioning system can be stopped running.

[0076] S204: When the fault information is a power generation module fault in the first outdoor unit, determine the control strategy as the fourth control strategy.

[0077] In this embodiment, when the power generation module in the first outdoor unit fails, it indicates that the power generation module in the photovoltaic type outdoor unit cannot receive light energy, and the received light energy cannot be converted into electrical energy for use when the first outdoor unit fails. In order to ensure the normal operation of the entire air conditioning system and improve the user experience, when there is a sixth outdoor unit in a shutdown state in the plurality of outdoor units, the control strategy can be determined as the fourth control strategy. When there is no sixth outdoor unit in a shutdown state in the plurality of outdoor units, it indicates that there is no sixth outdoor unit that can be switched in the air conditioning system. At this time, in order to ensure the reliability of the entire air conditioning system, the entire air conditioning system can be stopped running.

[0078] S205: When the control strategy is the fourth control strategy, control the first outdoor unit to switch from the running state to the shutdown state and control the sixth outdoor unit to switch from the shutdown state to the running state.

[0079] S206: After determining the second outdoor unit, obtain the first light information of the environment where the first outdoor unit is located.

[0080] In the embodiment, after the second outdoor unit is determined, the light condition of the environment where the first outdoor unit is located needs to be acquired to determine whether the first outdoor unit can receive light energy. The first light information includes existing light and non-existing light. When the first light information is existing light, it indicates that the first outdoor unit can receive light energy, and when the first light information is non-existing light, it indicates that the first outdoor unit cannot receive light energy.

[0081] S207: Determine whether the first light information is existing light.

[0082] S208: When it is determined that the first light information is existing light, determine that the control strategy is the first control strategy.

[0083] In the embodiment, after it is determined that the first light information is existing light, it indicates that the first outdoor unit meets the switching condition and the first outdoor unit can receive light energy, and at this time, the control strategy is determined as the first control strategy.

[0084] S209: When the control strategy is the first control strategy, control the first outdoor unit to operate in the first mode and control the second outdoor unit to switch from the stop state to the operating state.

[0085] In one embodiment, the first outdoor unit is controlled to operate in the first mode, including:

[0086] The inverter module in the first outdoor unit is controlled to convert the received light energy into electrical energy;

[0087] The inverter module is controlled to deliver the converted electrical energy to the energy storage module in the first outdoor unit, so that the energy storage module stores the received electrical energy.

[0088] Wherein, the power generation module acquires light energy and delivers the light energy to the inverter module, the light energy is converted into electrical energy through the inverter module, the energy storage module in the first outdoor unit is used for energy storage, and when the first outdoor unit resumes normal operation, the electrical energy stored in the energy storage module can be used for operation, so as to reduce the consumption of grid electrical energy and maximize the benefits of the first outdoor unit during the fault period.

[0089] In another embodiment, the first outdoor unit is controlled to operate in the first mode, including:

[0090] The inverter module in the first outdoor unit is controlled to convert the received light energy into electrical energy;

[0091] The inverter module is controlled to deliver the converted electrical energy to the grid to supply power to the grid.

[0092] Wherein, in the first outdoor unit, the inverter module converts light energy into electrical energy, and then delivers the converted electrical energy to the power grid, so that the power grid can use the delivered electrical energy to power other household appliances, thereby reducing the consumption of power grid electrical energy and maximizing the benefits of the first outdoor unit during a fault.

[0093] S210: When the first illumination information is determined to be no illumination, the control strategy is determined to be a fifth control strategy.

[0094] S211: When the control strategy is the fifth control strategy, the first outdoor unit is controlled to switch from the running state to the shutdown state, and the second outdoor unit is controlled to switch from the shutdown state to the running state.

[0095] In this embodiment, for steps S210 and S211, after determining that the first illumination information is no illumination, it is determined that the first outdoor unit meets the switching condition but cannot receive light energy. At this time, the control strategy is determined to be the fifth control strategy. When the control strategy is the fifth control strategy, the switching of the first outdoor unit can be directly performed. It should be noted that if the photovoltaic outdoor unit is not shut down due to failure of its own power generation module, when the photovoltaic outdoor unit is in the shutdown state, it is only indicated that the indoor unit is no longer controlled to run, but the photovoltaic outdoor unit is still running in the first mode. The first mode is as described above, and this embodiment will not be described here.

[0096] The control method of the air conditioning system provided in this embodiment can determine the first outdoor unit with a fault in the air conditioning system without directly controlling the first outdoor unit to stop running. Instead, different control strategies are executed on multiple outdoor units based on the fault information and type information of the first outdoor unit, thereby improving the user experience and maximizing the benefits of the first outdoor unit during a fault.

[0097] Reference Figure 3 , Figure 3 This is another flowchart of a control method of an air conditioning system provided by the embodiment. The control method of the air conditioning system provided in this embodiment is applied to a hybrid air conditioning system. The control method of the air conditioning system includes the following steps:

[0098] S301: When it is determined that there is a first outdoor unit with a fault in a running state in the multiple outdoor units, determine the fault information corresponding to the first outdoor unit and the type information corresponding to the first outdoor unit.

[0099] In this embodiment, the fault information in step S301 is any module failure in the first outdoor unit, and the type information is non-photovoltaic type.

[0100] S302: Determine a third outdoor unit in a shutdown state from at least one photovoltaic outdoor unit.

[0101] In the embodiment, in the case that the first outdoor unit of the non-photovoltaic type has a fault, in order to ensure the maximization of benefits during the failure of the first outdoor unit, it is determined whether there is a third outdoor unit in a shutdown state in the at least one photovoltaic outdoor unit, to determine whether the first outdoor unit meets the switching condition of switching from the non-photovoltaic outdoor unit to the photovoltaic outdoor unit. When there is a third outdoor unit in a shutdown state in the at least one photovoltaic outdoor unit, it is determined that the first outdoor unit meets the switching condition between different types of outdoor units, and the subsequent S303 step is executed. When there is no third outdoor unit in a shutdown state in the at least one photovoltaic outdoor unit, it is determined whether there is a seventh outdoor unit in a shutdown state in the at least one non-photovoltaic outdoor unit, to determine whether the first outdoor unit meets the switching condition of switching from the non-photovoltaic outdoor unit to the non-photovoltaic outdoor unit. When there is a seventh outdoor unit in a shutdown state in the at least one non-photovoltaic outdoor unit, it is determined that the first outdoor unit meets the switching condition between the same type of outdoor units, and the first outdoor unit is controlled to switch from the running state to the shutdown state and the seventh outdoor unit is controlled to switch from the shutdown state to the running state. When there is no seventh outdoor unit in a shutdown state in the at least one non-photovoltaic outdoor unit, in order to ensure the reliability of the entire air conditioning system, the entire air conditioning system is controlled to stop running.

[0102] S303: After determining the third outdoor unit, the second light information of the environment where the third outdoor unit is located is obtained.

[0103] In the embodiment, after determining the third outdoor unit, the light condition of the environment where the third outdoor unit is located needs to be obtained to determine whether the third outdoor unit can receive light energy. The second light information includes the presence of light and the absence of light. When the second light information is the presence of light, it indicates that the third outdoor unit can receive light energy, and when the second light information is the absence of light, it indicates that the third outdoor unit cannot receive light energy.

[0104] S304: Determine whether the second light information is the presence of light.

[0105] S305: When it is determined that the second light information is the presence of light, it is determined that the control strategy is the second control strategy.

[0106] In the embodiment, after determining that the second light information is the presence of light, since the third outdoor unit can supply power to itself in the presence of light to reduce the consumption of electrical energy of the power grid, when the third outdoor unit is running, the third outdoor unit can be allowed to bear more load when the light is strong, so as to reduce the load borne by the non-photovoltaic outdoor unit and further reduce the consumption of electrical energy of the power grid, thereby ensuring the maximization of benefits during the failure of the first outdoor unit.

[0107] S306: When the control strategy is the second control strategy, the first outdoor unit is controlled to switch from the running state to the shutdown state, the third outdoor unit is controlled to switch from the shutdown state to the running state, and the third outdoor unit is controlled to run in the second mode during the running of the third outdoor unit.

[0108] In this embodiment, the third outdoor unit is controlled to run in the second mode, including:

[0109] The third outdoor unit is controlled to run in the target running parameter.

[0110] The target running parameter can be determined in the following manner:

[0111] When the second light information is that there is light, the light corresponding light level is determined;

[0112] According to the light level, the load information corresponding to the third outdoor unit is determined;

[0113] According to the load information, the target running parameter corresponding to the third outdoor unit is determined.

[0114] Specifically, the light level can be a first light level, and the light level can also be a second light level, which is higher than the first light level. For different light levels, a corresponding relationship between the light level and the load information required to be borne by the photovoltaic outdoor unit and the load information required to be borne by the non-photovoltaic outdoor unit can be set in advance, and the above-mentioned corresponding relationship is stored in the controller. After determining the light corresponding to the light level, the corresponding load information of the third outdoor unit can be determined according to the corresponding relationship. According to the load information, the running parameter corresponding to the outdoor unit of different types can be determined according to the prior art, and the determination method of the running parameter in this embodiment is not described. When the light level is the first light level, the photovoltaic outdoor unit generates less power, and the photovoltaic outdoor unit can be set to bear less load, and the non-photovoltaic outdoor unit bears more load. When the light level is the second light level, the photovoltaic outdoor unit generates more power, and the photovoltaic outdoor unit can be set to bear more load, and the non-photovoltaic outdoor unit bears less load, which can be referred to in Table 1. Through the above-mentioned manner, the power consumption of the power grid can be reduced as much as possible, and the maximization of benefits during the failure of the first outdoor unit is ensured.

[0115] Table 1 Load borne by photovoltaic outdoor unit and non-photovoltaic outdoor unit

[0116] Illumination level Load assumed by the photovoltaic outdoor unit Load assumed by the non-photovoltaic outdoor unit First illumination level A％ C% (A < C) Second illumination level B％ D% (B > D)

[0117] S307: When it is determined that the second light information does not exist, the control strategy is determined to be the sixth control strategy.

[0118] S308: When the control strategy is the sixth control strategy, the third outdoor unit is controlled to run in the fourth mode.

[0119] In the embodiment, for the steps S307 and S308, when the second lighting information does not exist light, the third outdoor unit cannot realize the conversion of electric energy, at this time, the third outdoor unit is controlled to run in the fourth mode. The fourth mode can be understood as the operation mode consistent with the non-photovoltaic outdoor unit. It should be noted that if the photovoltaic outdoor unit is not due to its own power generation module failure, when the photovoltaic outdoor unit is in the shutdown state, only the indoor unit is no longer controlled to run, but the photovoltaic outdoor unit is still running in the first mode. The first mode is described above, and the embodiment will not be repeated here.

[0120] The control method of the air conditioning system provided in the embodiment determines that there is a fault in the first outdoor unit in the air conditioning system, without directly controlling the first outdoor unit to stop running, but through the fault information and type information of the first outdoor unit, different control strategies are performed on the plurality of outdoor units, the use experience of the user is improved, and the benefits during the failure of the first outdoor unit are maximized.

[0121] Reference Figure 4 , Figure 4 Another flowchart of the control method of the air conditioning system is provided for the embodiment. The control method of the air conditioning system provided in the embodiment is applied to a hybrid air conditioning system. The control method of the air conditioning system includes the following steps:

[0122] S401: When it is determined that there is a first outdoor unit fault in a running state in the plurality of outdoor units, determine the fault information corresponding to the first outdoor unit and the type information corresponding to the first outdoor unit.

[0123] In the embodiment, the type information in the step S401 is photovoltaic type.

[0124] S402: Determine whether the fault information is a non-power generation module fault in the first outdoor unit.

[0125] In the embodiment, the photovoltaic outdoor unit is provided with a power generation module, an inverter module and an energy storage module. The fault of the power generation module and the non-power generation module in the photovoltaic outdoor unit is determined to determine whether the photovoltaic air conditioner can receive light energy.

[0126] S403: When it is determined that the fault information is a non-power generation module fault in the first outdoor unit, determine a fourth outdoor unit in a shutdown state from at least one photovoltaic outdoor unit.

[0127] In the embodiment, when the non-power generation module in the first outdoor unit of the photovoltaic type fails, it is indicated that the first outdoor unit can receive light energy and can convert the received light energy into electrical energy for use, so as to maximize the benefits during the failure of the first outdoor unit. Whether there is a fourth outdoor unit in a shutdown state in at least one photovoltaic outdoor unit is judged to determine whether the first outdoor unit meets the switching condition. When there is a fourth outdoor unit in a shutdown state in at least one photovoltaic outdoor unit, it is determined that the first outdoor unit meets the switching condition, and the step S404 is executed. When there is no fourth outdoor unit in a shutdown state in at least one photovoltaic outdoor unit, whether there is an eighth outdoor unit in a shutdown state in at least one non-photovoltaic outdoor unit is determined. When there is an eighth outdoor unit in a shutdown state in at least one non-photovoltaic outdoor unit, third light information of an environment where the first outdoor unit is located is obtained. When the third light information is that there is light, the first outdoor unit is controlled to operate in a first mode and the eighth outdoor unit is switched from a stopped state to a running state (the first mode can refer to the above description, and the embodiment will not be described here). When the third light information is that there is no light, the first outdoor unit is switched from a running state to a stopped state and the eighth outdoor unit is switched from a stopped state to a running state. When there is no eighth outdoor unit in a shutdown state in at least one non-photovoltaic outdoor unit, in order to ensure the reliability of the entire air conditioning system, the entire air conditioning system is controlled to stop operating.

[0128] S404: Determine whether there is a fifth outdoor unit in a running state in at least one non-photovoltaic outdoor unit.

[0129] In the embodiment, when the fifth outdoor unit in a running state is determined from at least one non-photovoltaic outdoor unit, the fifth outdoor unit is powered by the energy storage module in the first outdoor unit to reduce the consumption of electrical energy of the power grid and maximize the benefits during the failure of the first outdoor unit.

[0130] S405: When it is determined that there is a fifth outdoor unit in a running state in at least one non-photovoltaic outdoor unit, the control strategy is determined to be a third control strategy.

[0131] S406: When the control strategy is the third control strategy, the first outdoor unit is controlled to operate in a third mode and the fourth outdoor unit is switched from a shutdown state to a running state.

[0132] For the steps S405 and S406, the first outdoor unit is controlled to operate in the third mode, which includes:

[0133] The energy storage module in the first outdoor unit is controlled to power the fifth outdoor unit.

[0134] S407: When it is determined that the failure information is a failure of the power generation module in the first outdoor unit, the control strategy is determined to be a seventh control strategy.

[0135] In the embodiment, when the power generation module in the first outdoor unit of the photovoltaic type fails, it is indicated that the first outdoor unit cannot receive light energy, and the conversion of the received light energy into electrical energy cannot be realized. In order to ensure the normal operation of the entire air conditioning system and improve the user experience, when there is a ninth outdoor unit in a stop state in at least one photovoltaic outdoor unit or there is a ninth outdoor unit in a stop state in at least one non-photovoltaic outdoor unit, the control strategy is determined to be the seventh control strategy. When there is no ninth outdoor unit in a stop state in at least one photovoltaic outdoor unit and there is no ninth outdoor unit in a stop state in at least one non-photovoltaic outdoor unit, in order to ensure the reliability of the entire air conditioning system, the entire air conditioning system can be stopped running.

[0136] S408: When the control strategy is the seventh control strategy, the first outdoor unit is switched from the running state to the stop state, and the ninth outdoor unit is switched from the stop state to the running state.

[0137] In the embodiment, in order to ensure the normal operation of the entire air conditioning system, after the ninth outdoor unit is determined, the first outdoor unit is switched to the ninth outdoor unit to run.

[0138] S409: When it is determined that there is no fifth outdoor unit in a running state in at least one non-photovoltaic outdoor unit, fourth light information of an environment in which the first outdoor unit is located is obtained.

[0139] In the embodiment, when there is no fifth outdoor unit in a running state in at least one non-photovoltaic outdoor unit, the energy storage module in the first outdoor unit cannot supply power to the non-photovoltaic outdoor unit in a running state. At this time, the energy storage module in the first outdoor unit can be used for energy storage, and when the first outdoor unit resumes normal operation, the electrical energy stored in the energy storage module can be used for operation, so as to reduce the consumption of grid electrical energy and maximize the benefits of the first outdoor unit during the failure period. Or, after the inverter module in the first outdoor unit converts the light energy into electrical energy, the converted electrical energy is delivered to the grid, so that the grid can use the delivered electrical energy to supply power to other household appliances, thereby reducing the consumption of grid electrical energy and maximizing the benefits of the first outdoor unit during the failure period. The energy storage by the energy storage module and the power supply to the grid are determined by the light information.

[0140] S410: Determine whether the fourth light information is that there is light.

[0141] S411: When the fourth light information is that there is light, it is determined that the control strategy is the eighth control strategy.

[0142] S412: when the control strategy is the eighth control strategy, controlling the first outdoor unit to run in the first mode and controlling the fourth outdoor unit to switch from the stop state to the running state.

[0143] In this embodiment, for steps S410-S412, only when there is light, the first outdoor unit is controlled to run in the first mode, and the first outdoor unit is controlled to switch to the fourth outdoor unit for running to ensure normal operation of the air conditioning system. The first mode can refer to the description above, which is not repeated here.

[0144] S413: when the third light information is no light, determining that the control strategy is the ninth control strategy.

[0145] S414: when the control strategy is the ninth control strategy, controlling the first outdoor unit to switch from the running state to the stop state and controlling the fourth outdoor unit to switch from the stop state to the running state.

[0146] In this embodiment, for steps S413 and S414, after it is determined that the third light information is no light, it is indicated that the first outdoor unit meets the switching condition but the first outdoor unit cannot receive light energy, so the first outdoor unit is directly controlled to switch. It should be noted that if the photovoltaic outdoor unit is not stopped due to failure of its own power generation module, when the photovoltaic outdoor unit is in the stop state, it is only indicated that the indoor unit is no longer controlled to run, but the photovoltaic outdoor unit is still running in the first mode. The first mode is described above and is not repeated here.

[0147] The control method of the air conditioning system provided in this embodiment does not directly control the first outdoor unit to stop running when it is determined that the first outdoor unit in the air conditioning system has a fault, but different control strategies are executed on multiple outdoor units through the fault information and type information of the first outdoor unit, which improves the user experience and maximizes the benefits during the fault of the first outdoor unit.
