[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0040] It should be noted that all directional indications, such as upper, lower, left, right, front, back, etc., in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0041] The terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0042] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected. For a person of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, when describing the pipeline, the "connected" and "connected" used in the present application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0043] In the embodiments of the present application, the words such as "exemplary" or "for example" are used to represent as an example, illustration or description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words such as "exemplary" or "for example" are intended to present the relevant concept in a specific manner.

[0044] Since the current air conditioner does not support simultaneous operation of the cooling mode and the heating mode, when a part of the indoor unit of the air conditioner operates in the cooling mode, and another part of the indoor unit operates in the heating mode, it will cause the part of the indoor unit of the air conditioner to be in an abnormal operation mode, and even cause the indoor unit in the abnormal operation mode to stop running, so that the air conditioner cannot operate normally, greatly affecting the user's experience.

[0045] Based on this, this application provides a control method for an air conditioner. Upon receiving an instruction to start multiple target indoor units selected by the user, and assuming all target indoor units are in a powered-off state, the method acquires the operating parameters (such as outdoor ambient temperature, indoor ambient temperature, and set priority) of each target indoor unit. Then, based on the preset seasonal temperature and the operating parameters of each target indoor unit, it calculates the initial operating mode of each target indoor unit. If two target indoor units have different initial operating modes, the method controls all target indoor units to operate in the initial operating mode of the target indoor unit with the highest set priority. This resolves the mode conflict in the air conditioner and greatly improves the user experience.

[0046] Figure 1 This is a schematic diagram illustrating the composition of an air conditioner according to an embodiment of this application. Figure 1 As shown, the air conditioner 100 includes a controller 11, multiple indoor units 12, multiple wired controllers 13, at least one outdoor unit 14, and a throttling device 15. Figure 1 (Not shown in the image).

[0047] In some embodiments, the controller 11 is connected to multiple indoor units 12 via a communication bus for centralized management and control of the connected indoor units 12.

[0048] In some embodiments, the indoor unit 12 is typically installed indoors, and there is a pipe connection between the indoor unit 12 and the outdoor unit 14. This pipe includes a gas pipe for transporting gaseous refrigerant and a liquid pipe for transporting two-phase refrigerant. Furthermore, the indoor unit 12 includes components such as an indoor heat exchanger and an indoor unit fan.

[0049] In some embodiments, the wired controller 13 can be connected to the indoor unit 12 in a wired or wireless manner to control its corresponding indoor unit.

[0050] In some embodiments, the outdoor unit 14 is typically installed outdoors to assist in heat exchange in the indoor environment. The outdoor unit 14 includes components such as a compressor, a four-way valve, a gas-liquid separator, an outdoor heat exchanger, and an outdoor fan.

[0051] In some embodiments, the throttling device 15 is used to regulate the fluid flow rate in the gas-liquid pipe of the air conditioner 100 and to regulate the refrigerant flow rate.

[0052] In some embodiments, the throttling device 15 may be an electronic device, such as an electronic expansion valve, or a mechanical device, such as a capillary tube.

[0053] Taking an air conditioner 100 that includes two indoor units 12 and one outdoor unit 14 as an example, Figure 2 This is a schematic diagram of the structure of an air conditioner provided in an embodiment of this application. Figure 2As shown, the air conditioner 100 includes a controller 11 Figure 2 (not shown in the figure), two indoor units 12, an outdoor unit 14, and a throttling device 15.

[0054] The outdoor unit 14 includes an outdoor heat exchanger 141, a gas-liquid separator 142, a compressor 143, and a four-way valve 144. The indoor unit 12 includes an indoor heat exchanger 121.

[0055] In some embodiments, one end of the outdoor heat exchanger 141 is connected to the gas-liquid separator 142 via the four-way valve 144, and the other end is connected to the throttling device 15. The outdoor heat exchanger 141 has a first port for passing refrigerant between the outdoor heat exchanger 141 and a suction port of the compressor 143 via the gas-liquid separator 142, and has a second port for passing refrigerant between the outdoor heat exchanger 141 and the throttling device 15. The outdoor heat exchanger 141 exchanges heat between the outdoor air and the heat transfer pipe connected between the first port and the second port. In cooling, the outdoor heat exchanger 141 works as a condenser, and in heating, the outdoor heat exchanger 141 works as an evaporator.

[0056] In some embodiments, one end of the gas-liquid separator 142 is connected to the compressor 143, and the other end is connected to the outdoor heat exchanger 141 via the four-way valve 144. In the gas-liquid separator 142, the refrigerant flowing from the outdoor heat exchanger 141 to the compressor 143 via the four-way valve 144 is separated into gaseous refrigerant and liquid refrigerant. And the gaseous refrigerant is mainly supplied to the suction port of the compressor 143 from the gas-liquid separator 142.

[0057] In some embodiments, the compressor 143 is arranged between the throttling device 15 and the gas-liquid separator 142, for compressing the refrigerant delivered by the gas-liquid separator 142, and delivering the compressed refrigerant to the throttling device 15 via the four-way valve 144. The compressor 143 can be an inverter compressor with variable capacity based on inverter speed control.

[0058] In some embodiments, the compressor 143 can be provided in plurality, and the plurality of compressors are connected in parallel, and the number of the compressor 143 is not limited in the embodiments of the present application.

[0059] In some embodiments, the four ports of the four-way valve 144 are respectively connected to the compressor 143, the outdoor heat exchanger 141, the gas-liquid separator 142, and at least one throttling device 15. The four-way valve 144 is used to realize mutual conversion between cooling and heating by changing the flow direction of the refrigerant in the system pipeline.

[0060] In some embodiments, the indoor heat exchanger 121 has a third port for passing liquid refrigerant between the throttling device 15, and a fourth port for passing gaseous refrigerant between the discharge port of the compressor 143. The indoor heat exchanger 121 exchanges heat between the refrigerant flowing in the heat transfer pipe connected between the third port and the fourth port and the indoor air. In cooling, the indoor heat exchanger 121 works as an evaporator, and in heating, the indoor heat exchanger 121 works as a condenser.

[0061] In the embodiments shown in the present application, the controller 11 refers to a device that can generate operation control signals according to instruction operation codes and timing signals to instruct the air conditioner 100 to execute control instructions. Exemplarily, the controller can be a central processing unit (CPU), a general processor network processor (NP), a digital signal processing (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller can also be other devices with processing functions, such as circuits, devices, or software modules, and the embodiments of the present application do not make any limitation thereto.

[0062] In addition, the controller 11 can be used to control the operation of various components in the air conditioner 100, so that the various components of the air conditioner 100 operate to achieve the predetermined functions of the air conditioner.

[0063] In some embodiments, when the air conditioner 100 is cooling, the compressor 143 compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant and discharges it to the outdoor heat exchanger 141. The high-temperature and high-pressure gaseous refrigerant exchanges heat with the outdoor air in the outdoor heat exchanger 141, releases heat, and the released heat is taken to the outdoor ambient air. The refrigerant then changes phase and condenses into liquid or gas-liquid two-phase refrigerant. The refrigerant flows out of the outdoor heat exchanger 121, enters the throttling device 15, and is cooled and decompressed into low-temperature and low-pressure refrigerant. The low-temperature and low-pressure refrigerant exchanges heat with the indoor air in the indoor heat exchanger 121, absorbs the heat of the indoor air, lowers the indoor temperature, and achieves the cooling effect. The refrigerant then changes phase and evaporates into low-temperature and low-pressure gaseous refrigerant, which flows back into the compressor 143 to achieve the circulation of the refrigerant.

[0064] In some embodiments, when the air conditioner 100 is heating, the compressor 143 compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, and discharges it to the indoor heat exchanger 121. The high-temperature and high-pressure gaseous refrigerant exchanges heat with indoor air in the indoor heat exchanger 121, releases heat, and the released heat is brought to the indoor air, so that the indoor temperature is increased, realizing the heating effect. The refrigerant changes phase and condenses into liquid or gas-liquid two-phase refrigerant. The refrigerant flows out of the indoor heat exchanger 121, enters the throttling device 15, and is cooled and decompressed into low-temperature and low-pressure refrigerant. The low-temperature and low-pressure refrigerant exchanges heat with outdoor air in the outdoor heat exchanger 141, and the refrigerant changes phase and evaporates into low-temperature and low-pressure gaseous refrigerant, which flows back into the compressor 143, realizing the cyclic utilization of the refrigerant.

[0080] In some embodiments, the central controller 10 can be connected with multiple indoor units of the air conditioner through a communication bus, to centrally manage and control the multiple indoor units. For example, the central controller 10 can be connected with two indoor units 12 of the air conditioner 100 through a communication bus, so that the central controller 10 can centrally manage and control the two indoor units 12.

[0093] In some embodiments, the air conditioner 40 can include at least one outdoor unit, multiple indoor units, and can also include a fresh air unit. The fresh air unit is an air conditioning device that provides fresh air.

[0094] The embodiments provided by the present application will be specifically introduced below in conjunction with the drawings of the specification.

[0095] As Figure 12As shown, the embodiment of the present application provides a control method of an air conditioner. The method can be applied to the central controller provided by the embodiment of the present application, which is connected with multiple indoor units of the air conditioner through a communication bus, and can also be applied to the controller of the air conditioner. Hereinafter, the method is described in detail taking the controller of the air conditioner as an example. The method comprises:

[0096] In S101, the controller receives a starting instruction of a user.

[0097] The starting instruction is used to instruct to start multiple target indoor units selected by the user.

[0098] In some embodiments, when the user needs to use the air conditioner for cooling or heating, the user can select multiple target indoor units which need to be controlled in a centralized manner through the management interface of the terminal device, or can select multiple target indoor units which need to be controlled in a centralized manner through the control interface of the controller. Further, the starting instruction is issued to the multiple target indoor units, and the controller controls the multiple target indoor units in a centralized manner in response to the received starting instruction.

[0099] In some embodiments, before the starting instruction is issued to the multiple target indoor units, the user also needs to set the temperature and humidity for each target indoor unit.

[0100] In S102, the controller acquires the outdoor environment temperature, the indoor environment temperature of the indoor where each target indoor unit is located, and the set priority in the case that the running state of each target indoor unit is the shutdown state.

[0101] The running state comprises a startup state and a shutdown state, each target indoor unit corresponds to a set priority, and the set priority of each target indoor unit is different. In some embodiments, after receiving the starting instruction of the user, the controller first acquires the running state of all target indoor units, and then acquires the outdoor environment temperature, the indoor environment temperature of the indoor where each target indoor unit is located, and the set priority in the case that the running state of each target indoor unit is the shutdown state.

[0102] In some embodiments, in the case that the running state of each target indoor unit is the startup state, the running mode of each target indoor unit is kept unchanged.

[0103] In S103, the controller calculates the initial running mode of each target indoor unit according to the indoor environment temperature, the preset seasonal temperature, and the outdoor environment temperature.

[0104] The initial running mode comprises a heating mode and a cooling mode, and the preset seasonal temperature comprises a first preset seasonal temperature and a second preset seasonal temperature.

[0105] Optionally, the first preset seasonal temperature and the second preset seasonal temperature can be preset by the administrator or obtained by the controller from other air conditioners; there is no limitation on this.

[0106] Understandably, the preset seasonal temperature varies depending on the season. In spring and summer, the preset seasonal temperature is the first preset seasonal temperature, while in autumn and winter, the preset seasonal temperature is the second preset seasonal temperature.

[0107] In some embodiments, the controller calculates the initial operating mode of each target indoor unit based on the indoor ambient temperature, the preset seasonal temperature, and the outdoor ambient temperature.

[0108] For example, as shown in Table 1 below, the controller determines the initial operating mode of each target indoor unit based on the indoor ambient temperature Troom, the second preset seasonal temperature Th_on, the first preset seasonal temperature Tc_on, and the outdoor ambient temperature Toa.

[0109] Table 1

[0110]

[0111] (1) When the indoor ambient temperature Troom is lower than the second preset seasonal temperature Th_on for 24 hours and the outdoor ambient temperature Toa is lower than the difference between the first preset temperature T1 and the indoor ambient temperature Troom, the initial operating mode of the target indoor unit is heating mode.

[0112] Optionally, the first preset temperature is 50°C.

[0113] In some embodiments, if the air conditioner is as described above Figure 5 The air conditioner shown will initially operate in floor heating mode if the indoor ambient temperature Troom is lower than the second preset seasonal temperature Th_on for 24 hours and the outdoor ambient temperature Toa is lower than the difference between the first preset temperature T1 and the indoor ambient temperature Troom.

[0114] (2) When the indoor ambient temperature Troom is less than the difference between the second preset seasonal temperature Th_on and the second preset temperature T2, and the outdoor ambient temperature Toa is less than the difference between the first preset temperature T1 and the indoor ambient temperature Troom, the initial operating mode of the target indoor unit is the heating mode.

[0115] Optionally, the second preset temperature is 2℃.

[0116] In some embodiments, if the air conditioner is as described above Figure 5In the air conditioner shown, in a case where the indoor environment temperature Troom is less than a difference between the second preset seasonal temperature Th_on and the second preset temperature T2, and the outdoor environment temperature Toa is less than a difference between the first preset temperature T1 and the indoor environment temperature Troom, the initial operation mode of the target indoor unit is the floor heating mode.

[0117] (3) In a case where the indoor environment temperature Troom is greater than the first preset seasonal temperature Tc_on for 24 hours, and the outdoor environment temperature Toa is greater than a difference between the third preset temperature T3 and the indoor environment temperature Troom, the initial operation mode of the target indoor unit is the cooling mode.

[0118] Optionally, the third preset temperature is 40℃.

[0119] In some embodiments, in a case where the indoor unit of the air conditioner is a three-pipe indoor unit, in a case where the indoor environment temperature Troom is greater than the first preset seasonal temperature Tc_on for 24 hours, and the outdoor environment temperature Toa is greater than a difference between the third preset temperature T3 and the indoor environment temperature Troom, the initial operation mode of the target indoor unit is the refreshing mode.

[0120] (4) In a case where the indoor environment temperature Troom is greater than a sum of the first preset seasonal temperature Tc_on and the second preset temperature T2, and the outdoor environment temperature Toa is greater than a difference between the third preset temperature T3 and the indoor environment temperature Troom, the initial operation mode of the target indoor unit is the cooling mode.

[0121] In some embodiments, in a case where the indoor unit of the air conditioner is a three-pipe indoor unit, in a case where the indoor environment temperature Troom is greater than a sum of the first preset seasonal temperature Tc_on and the second preset temperature T2, and the outdoor environment temperature Toa is greater than a difference between the third preset temperature T3 and the indoor environment temperature Troom, the initial operation mode of the target indoor unit is the refreshing mode.

[0122] (5) In a case where the indoor environment temperature Troom is greater than or equal to a sum of the second preset seasonal temperature Th_on and the fourth preset temperature T4, and less than or equal to a difference between the first preset seasonal temperature Tc_on and the fourth preset temperature T4, the initial operation mode of the target indoor unit is the air supply mode.

[0123] Optionally, the fourth preset temperature is 1℃.

[0124] (6) When any one of the above (1) to (5) is not met, the target indoor unit keeps the previous operation mode.

[0125] In some embodiments, when the indoor environment temperature of the indoor unit, the preset seasonal temperature, and the outdoor environment temperature first meet any of the conditions (1) to (5) above, the initial operation mode of the target indoor unit is the air supply mode.

[0126] In some embodiments, if the air conditioner further comprises a fresh air unit, the operation state of the fresh air unit is always open, and the mode of the fresh air unit is the automatic mode.

[0127] In some embodiments, if the initial operation modes of the two target indoor units among the multiple target indoor units are different, the controller controls the multiple target indoor units to operate in the initial operation mode of the target indoor unit with the highest set priority.

[0128] In some embodiments, after the controller calculates the initial operation mode of each target indoor unit, the controller determines whether the initial operation modes of the multiple target indoor units are all the same.

[0129] In some embodiments, if the initial operation modes of the two target indoor units among the multiple target indoor units are different, the controller controls the multiple target indoor units to operate in the initial operation mode of the target indoor unit with the highest set priority.

[0130] For example, the multiple target indoor units selected by the user include a first target indoor unit, a second target indoor unit, and a third target indoor unit, and the target indoor unit with the highest set priority is the first target indoor unit. If the initial operation mode of the first target indoor unit is different from the initial operation mode of the second target indoor unit, the controller controls the first target indoor unit, the second target indoor unit, and the third target indoor unit to operate in the initial operation mode of the first target indoor unit.

[0131] Alternatively, if the initial operation mode of the first target indoor unit is different from the initial operation mode of the third target indoor unit, the controller controls the first target indoor unit, the second target indoor unit, and the third target indoor unit to operate in the initial operation mode of the first target indoor unit.

[0132] Alternatively, if the initial operation mode of the second target indoor unit is different from the initial operation mode of the third target indoor unit, the controller controls the first target indoor unit, the second target indoor unit, and the third target indoor unit to operate in the initial operation mode of the first target indoor unit.

[0133] In some embodiments, if the initial operation modes of the multiple target indoor units are all the same, the controller calculates a first target operation mode according to the average of the indoor environment temperatures of the rooms where the target indoor units are located, the preset seasonal temperature, and the outdoor environment temperature, and controls the multiple target indoor units to operate in the first target operation mode.

[0134] It should be noted that the calculation method of the first target operation mode can refer to the specific description of the calculation of the initial operation mode of each target indoor unit in step S103 above, and only the indoor environment temperature Troom is replaced by the average of the indoor environment temperature of the indoor where each target indoor unit is located. Here, no further description is given.

[0135] In some embodiments, the controller calculates a second target operation mode according to the average of the indoor environment temperature of the indoor where the at least one first target indoor unit is located, the preset seasonal temperature, and the outdoor environment temperature, and controls the plurality of target indoor units to operate in the second target operation mode, in the case that the operating state of at least one first target indoor unit is the on state, and the operating state of at least one second target indoor unit is the off state.

[0136] It should be noted that the calculation method of the second target operation mode can refer to the specific description of the calculation of the initial operation mode of each target indoor unit in step S103 above, and only the indoor environment temperature Troom is replaced by the average of the indoor environment temperature of the indoor where the at least one first target indoor unit is located. Here, no further description is given.

[0137] In addition, if the number of first target indoor units in the on state is only one, the second target operation mode can be calculated according to the indoor environment temperature of the indoor where the first target indoor unit is located, the preset seasonal temperature, and the outdoor environment temperature.

[0138] For example, the plurality of target indoor units selected by the user includes a first target indoor unit, a second target indoor unit, and a third target indoor unit. In the case that the operating state of the first target indoor unit is the on state, and the operating state of the second target indoor unit and the third target indoor unit is the off state, the second target operation mode is calculated according to the indoor environment temperature of the indoor where the first target indoor unit is located, the preset seasonal temperature, and the outdoor environment temperature, and the first target indoor unit, the second target indoor unit, and the third target indoor unit are controlled to operate in the second target operation mode.

[0139] Alternatively, in the case that the operating state of the second target indoor unit is the on state, and the operating state of the first target indoor unit and the third target indoor unit is the off state, the second target operation mode is calculated according to the indoor environment temperature of the indoor where the second target indoor unit is located, the preset seasonal temperature, and the outdoor environment temperature, and the first target indoor unit, the second target indoor unit, and the third target indoor unit are controlled to operate in the second target operation mode.

[0140] Or, in the case where the running state of the third target indoor unit is the start-up state, and the running states of the first target indoor unit and the second target indoor unit are the shut-down state, the second target running mode is calculated according to the indoor environment temperature of the indoor where the third target indoor unit is located, the preset seasonal temperature and the outdoor environment temperature, and the first target indoor unit, the second target indoor unit and the third target indoor unit are controlled to run in the second target running mode.

[0141] Or, in the case where the running states of the first target indoor unit and the second target indoor unit are the start-up state, and the running state of the third target indoor unit is the shut-down state, the second target running mode is calculated according to the average value of the indoor environment temperatures of the indoors where the first target indoor unit and the second target indoor unit are located, the preset seasonal temperature and the outdoor environment temperature, and the first target indoor unit, the second target indoor unit and the third target indoor unit are controlled to run in the second target running mode.

[0142] Or, in the case where the running states of the first target indoor unit and the third target indoor unit are the start-up state, and the running state of the second target indoor unit is the shut-down state, the second target running mode is calculated according to the average value of the indoor environment temperatures of the indoors where the first target indoor unit and the third target indoor unit are located, the preset seasonal temperature and the outdoor environment temperature, and the first target indoor unit, the second target indoor unit and the third target indoor unit are controlled to run in the second target running mode.

[0143] Or, in the case where the running states of the second target indoor unit and the third target indoor unit are the start-up state, and the running state of the first target indoor unit is the shut-down state, the second target running mode is calculated according to the average value of the indoor environment temperatures of the indoors where the second target indoor unit and the third target indoor unit are located, the preset seasonal temperature and the outdoor environment temperature, and the first target indoor unit, the second target indoor unit and the third target indoor unit are controlled to run in the second target running mode.

[0144] The complete flow of the control method of the air conditioner will be described below with reference to the flow chart shown in Figure 13

[0145] As shown in Figure 13 , the control process starts:

[0146] S1, receiving the start-up instruction of the user.

[0147] judging whether the running states of all target indoor units are the start-up state.

[0148] If yes, the following step S6 is executed.

[0149] If no, the following step S2 is executed.

[0150] ​S2, judging whether the running state of each target indoor unit is a shutdown state.

[0151] If yes, the following step S3 and step S4 are executed.

[0152] If no, the following step S9 and step S10 are executed.

[0153] S3, acquiring the outdoor environment temperature, the indoor environment temperature of the indoor where each target indoor unit is located, and the set priority.

[0154] S4, calculating the initial running mode of each target indoor unit according to the indoor environment temperature, the preset seasonal temperature, and the outdoor environment temperature.

[0155] judging whether the initial running mode of each target indoor unit is the same.

[0156] If yes, the following step S7 and step S8 are executed.

[0157] If no, the following step S5 is executed.

[0158] S5, controlling the multiple target indoor units to run in the initial running mode of the target indoor unit with the highest set priority.

[0159] S6, keeping the running mode of each target indoor unit unchanged.

[0160] S7, calculating the first target running mode according to the average value of the indoor environment temperature of the indoor where each target indoor unit is located, the preset seasonal temperature, and the outdoor environment temperature.

[0161] S8, controlling the multiple target indoor units to run in the first target running mode.

[0162] S9, calculating the second target running mode according to the average value of the indoor environment temperature of the indoor where the first target indoor unit in the shutdown state is located, the preset seasonal temperature, and the outdoor environment temperature.

[0163] S10, controlling the multiple target indoor units to run in the second target running mode.

[0164] Based on Figure 12In the embodiment shown, the control method of the air conditioner provided by the embodiment of the present application comprises the following steps: after receiving an instruction for starting a plurality of target indoor units selected by a user, obtaining the running parameters (such as the outdoor environment temperature, the indoor environment temperature, and the set priority) of each target indoor unit in the case that the running state of each target indoor unit is the shutdown state, and then calculating the initial running mode of each target indoor unit according to the preset seasonal temperature and the running parameters of each target indoor unit, in the case that the initial running mode of two target indoor units among the plurality of target indoor units is different, controlling the plurality of target indoor units to run in the initial running mode of the target indoor unit with the highest set priority. In this way, it can be determined whether a mode conflict will occur based on the determined initial running mode, and in the case that a mode conflict occurs, all indoor units are controlled based on the initial running mode of the target indoor unit with the highest set priority, so as to ensure the normal running of the air conditioner and greatly improve the user experience.

[0165] In some embodiments, as shown in the control method further comprises the following steps: Figure 14

[0166] S201, the controller displays a control interface of the air conditioner.

[0167] The control interface is used to display a first indoor unit list of the air conditioner; the first indoor unit list comprises a plurality of indoor units arranged in sequence.

[0168] It can be understood that the controller can control the display screen to display the control interface of the air conditioner. Alternatively, step S201 can also be performed by a central controller, which displays the control interface of the air conditioner on a central control screen. For example, the control interface can be as shown in the control interface shown in the above Figure 10

[0169] In some embodiments, the order of the plurality of indoor units arranged in sequence in the first indoor unit list is determined based on the preset coding address of the indoor unit and the preset coding address of the outdoor unit.

[0170] S202, the controller receives a list adjustment operation of the user on the control interface.

[0171] The list adjustment operation is used to adjust the order of each indoor unit in the first indoor unit list.

[0172] Alternatively, the list adjustment operation can be completed by the user's finger or by a touch device such as a touch pen compatible with the controller, without limitation.

[0173] For example, the list adjustment operation can be a drag operation of the user on the control interface. For example, Figure 15 ​​As shown, the control interface includes a first indoor unit list, and the first indoor unit list has, in order from top to bottom, the master bedroom indoor unit, the study indoor unit, the secondary bedroom indoor unit, and the baby room indoor unit. After receiving a user's drag operation on the control interface for the master bedroom indoor unit, the controller adjusts the order of the master bedroom indoor unit in the first indoor unit list, for example, to a position after the baby room indoor unit, and the adjusted control interface is as shown in Figure 16 As shown, the control interface includes a second indoor unit list, and the second indoor unit list has, in order from top to bottom, the baby room indoor unit, the master bedroom indoor unit, the study indoor unit, and the secondary bedroom indoor unit.

[0174] S203, the controller displays an adjusted control interface in response to the list adjustment operation.

[0175] The adjusted control interface is used to display a second indoor unit list of the air conditioner, and the indoor units in the second indoor unit list have different arrangement orders from the first indoor unit list.

[0176] For example, if the first indoor unit list has, in order, the master bedroom indoor unit, the study indoor unit, the secondary bedroom indoor unit, and the baby room indoor unit, and the user's list adjustment operation on the control interface is to adjust the order of the indoor units in the first indoor unit list to the study indoor unit, the secondary bedroom indoor unit, the baby room indoor unit, and the master bedroom indoor unit, therefore, the second indoor unit list has, in order, the study indoor unit, the secondary bedroom indoor unit, the baby room indoor unit, and the master bedroom indoor unit, and the controller displays the adjusted second indoor unit list.

[0177] S204, the controller determines the set priority of each indoor unit according to the arrangement order of each indoor unit in the second indoor unit list.

[0178] In some embodiments, the set priority of each indoor unit in the second indoor unit list decreases in order from top to bottom.

[0179] For example, the indoor units in the second indoor unit list, in order from top to bottom, are the study indoor unit, the secondary bedroom indoor unit, the baby room indoor unit, and the master bedroom indoor unit, therefore, the set priority of the study indoor unit is higher than that of the secondary bedroom indoor unit, the set priority of the secondary bedroom indoor unit is higher than that of the baby room indoor unit, and the set priority of the baby room indoor unit is higher than that of the master bedroom indoor unit.
