Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning control method, an air conditioning device, an air conditioner, an electronic device and a storage medium. Background Art

[0002] At present, with the development of air-conditioning technology, the cooling capacity of air conditioners is getting larger and larger, and the maximum cooling capacity of a single system has reached 48HP or higher. The increase in the cooling capacity of a single system means that the unit output ratio at the lowest operating frequency of the single system compressor increases. Therefore, the problem caused by the use on the user side is that the cooling output does not match the actual user needs. On the other hand, due to the large differences in building envelope structures, light radiation, etc. in various regions, the actual selection of machines is often too large, which further amplifies the problem of mismatch between cooling output and actual user needs. Even if the compressor output is reduced to the minimum, the machine will still stop frequently after reaching the set temperature due to excessive output. The frequent start and stop of the compressor will cause the lubricating oil to fail to return to the compressor oil pool in time for effective lubrication. In addition, due to the frequent start and stop in a short period of time, it will not be possible to establish an effective exhaust superheat, and the lubricating oil of the compressor will be diluted and worn during operation.

[0003] Currently, no effective solution has been proposed to solve the problem in the prior art that the minimum output of the air conditioner does not match the actual user demand, resulting in frequent starts and stops of the compressor. Summary of the invention

[0042] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] The air conditioner described in the embodiment of the present invention includes an outdoor unit and at least two indoor units, and the air conditioner uses a variable frequency compressor. In view of the problem in the prior art that the minimum output of the air conditioner does not match the actual user demand, resulting in frequent start and stop of the compressor, the embodiment of the present invention provides an air conditioner control method, which determines the indoor unit with lower user demand in the air conditioner based on autonomous learning of user usage scenarios. When the outdoor unit operates according to the minimum output capacity and the compressor starts and stops frequently, the excess output is borne by the indoor unit with lower user demand, thereby improving the frequent start and stop of the compressor and improving the reliability of the compressor operation.

[0044] Figure 1 is a flow chart of an air conditioning control method provided by an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0045] S101, during the operation of the air conditioner, determining the indoor unit in a preset demand state according to the state information of each indoor unit, wherein the indoor unit in the preset demand state has no refrigerant flowing through it and / or the refrigerant flow rate is less than a preset flow rate.

[0046] S102, when the indoor environment temperature corresponding to the indoor unit that is not in the preset demand state and has been turned on approaches the set temperature, the outdoor unit is controlled to operate according to the minimum output capacity, and the number of starts and stops of the compressor is detected.

[0047] S103: If the number of compressor starts and stops is greater than or equal to the preset number, the indoor unit currently in the preset demand state is controlled to bear the excess output of the outdoor unit.

[0048] The preset demand state refers to a low user demand for the indoor unit, that is, a weak demand state. The measurement standard for the weak demand state can be set according to the actual situation. For any indoor unit, if the indoor unit is in a weak demand state, no refrigerant flows through the indoor unit or the indoor unit has refrigerant flowing through but the refrigerant flow rate is small. The preset flow rate can be set according to the actual situation. For example, the preset flow rate is slightly larger than the refrigerant flow rate corresponding to the low wind speed of the indoor unit.

[0049] When the indoor ambient temperature corresponding to the indoor unit that is not in the preset demand state and has been turned on approaches the set temperature, it means that the user's cooling / heating needs are met. At this time, the outdoor unit can operate at the minimum output capacity, that is, the compressor operates at the lowest frequency. Specifically detect the number of compressor starts and stops within the preset time. The preset time can be set according to actual conditions, for example, the preset time is set to 1 hour. The preset number of times can be set according to actual conditions, for example, the preset number of times is set to 3 times. If the number of compressor starts and stops within the preset time is greater than or equal to the preset number, it means that the compressor starts and stops frequently, and the current output capacity of the outdoor unit is in excess. Frequent starts and stops of the compressor will affect the reliable operation of the compressor.

[0050] By controlling the indoor unit currently in the preset demand state to bear the excess output of the outdoor unit, if the indoor unit in the preset demand state has no refrigerant flowing through it, after turning on the indoor unit, refrigerant flows through the indoor unit, so that the indoor unit can bear part of the output of the outdoor unit. If the indoor unit in the preset demand state has refrigerant flowing through it and the refrigerant flow rate is less than the preset flow rate, the refrigerant flow rate of the indoor unit is increased (for example, the air damper can be increased or the opening of the indoor throttling element can be increased), so that the indoor unit can bear part of the output of the outdoor unit. By controlling the indoor unit currently in the weak demand state, the excess output of the outdoor unit can be borne without increasing the output of the compressor.

[0051] This embodiment conducts autonomous learning based on user usage scenarios, and determines the indoor units with lower user usage demand (i.e., the indoor units in the preset demand state) according to the status information of each indoor unit during the operation of the air conditioner; when the outdoor unit operates at the minimum output capacity and the compressor starts and stops frequently, the indoor unit currently in the preset demand state is controlled to bear the excess output of the outdoor unit, and the air conditioner operation state is autonomously corrected to improve the frequent start and stop of the compressor, thereby improving the operating reliability of the compressor, solving the problem in the prior art that the minimum output of the air conditioner does not match the actual user demand, resulting in frequent start and stop of the compressor, improving the selection redundancy, and broadening the adaptability of product use.

[0052] The above-mentioned preset demand state can be one or more, which are described below respectively.

[0053] (1) A preset demand state

[0054] During the operation of the air conditioner, the indoor units in the preset demand state are determined according to the status information of each indoor unit, including: during the operation of the air conditioner, the status information of each indoor unit is recorded; according to the status information of each indoor unit, it is determined whether each indoor unit is in the preset demand state, and the indoor units in the preset demand state are recorded.

[0055] The status information of the indoor unit includes: indoor ambient temperature, indoor unit set temperature, indoor unit power on / off status and indoor unit fan status.

[0056] The preset demand state may be: in heating mode, the indoor ambient temperature is less than the first preset temperature, in cooling mode, the indoor ambient temperature is greater than the second preset temperature, and the indoor unit is in the shutdown state. The first preset temperature is used to determine whether heating is required, and the indoor ambient temperature is less than the first preset temperature, indicating that heating is required. The second preset temperature is used to determine whether cooling is required, and the indoor ambient temperature is greater than the second preset temperature, indicating that cooling is required. The first preset temperature and the second preset temperature can be set according to actual conditions, for example, the first preset temperature is set to 0°C, and the second preset temperature is set to 30°C. In heating mode, the indoor ambient temperature is very low, and the air conditioner should be turned on for heating normally, but in fact the user has not turned on the indoor unit, and there may be no one indoors. At this time, it can be considered that the user's demand for the use of this indoor unit is relatively weak. Similarly, in cooling mode, the indoor ambient temperature is very high, and the air conditioner should be turned on for cooling normally, but in fact the user has not turned on the indoor unit, and there may be no one indoors. At this time, it can be considered that the user's demand for the use of this indoor unit is relatively weak.

[0057] Of course, the preset demand state may also be other states with lower user demand set according to actual conditions.

[0058] For example, in the heating mode, the difference between the indoor unit set temperature and the indoor ambient temperature is greater than the third preset temperature, in the cooling mode, the difference between the indoor unit set temperature and the indoor ambient temperature is less than the fourth preset temperature, and the indoor unit wind speed is less than or equal to the preset wind speed. Among them, the third preset temperature is used to determine whether the heating demand is large. In the heating mode, the difference between the indoor unit set temperature and the indoor ambient temperature is greater than the third preset temperature, indicating that the heating demand is large. The fourth preset temperature is used to determine whether the cooling demand is large. In the cooling mode, the difference between the indoor unit set temperature and the indoor ambient temperature is less than the fourth preset temperature, indicating that the cooling demand is large. The third preset temperature and the fourth preset temperature can be set according to actual conditions. The fourth preset temperature is less than 0. For example, the third preset temperature is set to 10°C and the fourth preset temperature is set to -10°C. The preset wind speed is used to determine whether the indoor unit wind speed is low. The indoor unit wind speed is less than or equal to the preset wind speed, indicating that the indoor unit wind speed is low. The preset wind speed can be set according to actual conditions, for example, the preset wind speed is set to the medium wind speed. In this case, the indoor unit is in the on state, and refrigerant flows through the indoor unit, but because the wind speed limit is small, the refrigerant flow rate is also small. According to the user's set temperature, it is judged that the demand is large, but according to the state of the indoor unit's wind speed limit, it is judged that the actual supply is small. This may be an error in user operation. Using such an indoor unit to bear the excess output of the outdoor unit has little impact on the user.

[0059] For another example, in heating mode, the difference between the set temperature of the indoor unit and the indoor ambient temperature is greater than the fifth preset temperature, in cooling mode, the difference between the set temperature of the indoor unit and the indoor ambient temperature is less than the sixth preset temperature, and the indoor unit is only operating at the wind gear alone. In this case, the user turns on the air supply mode, and no refrigerant flows through the indoor unit. The fifth preset temperature is used to determine whether there is a heating demand according to the air conditioning control logic. In heating mode, the difference between the set temperature of the indoor unit and the indoor ambient temperature is greater than the fifth preset temperature, indicating that there is a heating demand. The sixth preset temperature is used to determine whether there is a cooling demand according to the air conditioning control logic. In cooling mode, the difference between the set temperature of the indoor unit and the indoor ambient temperature is less than the sixth preset temperature, indicating that there is a cooling demand. The fifth preset temperature and the sixth preset temperature can be set according to actual conditions. For example, the fifth preset temperature is set to 0°C and the sixth preset temperature is set to 0°C. In this case, the user only turns on the indoor fan, and the corresponding indoor unit does not participate in the refrigerant circulation. If the set temperature has a negative deviation from the ambient temperature during cooling, and a positive deviation from the ambient temperature during heating, it is considered that there is an actual need to turn on the unit. However, the user turns on the air supply mode at this time, so it is considered that the user has set it wrong or the user actually has no need to turn on the unit. Using such an indoor unit to bear the excess output of the outdoor unit has little impact on the user.

[0060] The indoor units in the preset demand state are recorded, specifically, the unique identification of each indoor unit in the preset demand state can be directly recorded, or a mark can be added for the indoor units in the preset demand state. Specifically, the detection and recording can be performed periodically, in real time, or triggered when the indoor unit state changes.

[0061] This embodiment can accurately determine the indoor unit in a preset demand state based on the status information of each indoor unit, and can be updated in time as the status of the indoor unit changes, thereby ensuring that the indoor unit in a weak demand state can be used in a targeted manner to share the excess output of the outdoor unit without affecting the user as much as possible, thereby avoiding frequent starting and stopping of the compressor.

[0062] Specifically, the indoor unit that is currently in a preset demand state is controlled to bear the excess output of the outdoor unit, including: controlling the outdoor unit to maintain the lowest output capacity operation; controlling an indoor unit that is currently in a preset demand state to allow the refrigerant to flow through the indoor unit or increase the refrigerant flow of the indoor unit, and detecting the number of compressor starts and stops within a preset time; if the number of compressor starts and stops is still greater than or equal to the preset number, controlling the next indoor unit that is currently in a preset demand state to allow the refrigerant to flow through the indoor unit or increase the refrigerant flow of the indoor unit, and detecting the number of compressor starts and stops within a preset time, and repeating this cycle until the number of compressor starts and stops is less than the preset number or all indoor units that are currently in the preset demand state are bearing the excess output.

[0063] When the number of compressor starts and stops is less than the preset number, the new indoor unit will no longer be controlled to share the excess output of the outdoor unit. The outdoor unit will maintain the minimum output capacity and the indoor unit that is already bearing the excess output will also maintain the current state. Afterwards, if the user's cooling / heating demand changes (for example, a user changes the set temperature), the compressor needs to increase the frequency. For the indoor unit that is currently bearing the excess output, as long as the user has not changed its state, it will be restored to the original weak demand state. When the compressor drops to the minimum frequency, the number of compressor starts and stops will be re-determined to perform the corresponding control operation of sharing the excess output.

[0064] This embodiment controls the indoor units in a preset demand state one by one according to the number of compressor starts and stops, so that the excess output of the outdoor unit can be shared more accurately to avoid excessive sharing.

[0065] (2) Multiple preset demand states

[0066] In this embodiment, at least two preset demand states are set, and a state priority is set. The higher the state priority, the less impact the indoor environment will have when the indoor unit in this state bears excess output. The indoor units in each preset demand state are recorded separately.

[0067] Specifically, during the operation of the air conditioner, the indoor unit in the preset demand state is determined according to the state information of each indoor unit, including: during the operation of the air conditioner, the state information of each indoor unit is recorded; the indoor unit in the preset demand state is determined according to the state information of each indoor unit, and the indoor units in various preset demand states are recorded respectively. Among them, the state information includes: indoor ambient temperature, indoor unit set temperature, indoor unit on / off state and indoor unit windshield state. The explanation of terms that are the same or corresponding to the above embodiment will not be repeated in this embodiment.

[0068] This embodiment sets a plurality of preset demand states and sets state priorities. The higher the state priority, the less impact the indoor environment will have when the indoor unit in this state bears excess output. Thus, the indoor unit can be controlled to share the excess output of the outdoor unit according to the state priority, thereby more effectively reducing the impact on the indoor environment.

[0069] In the case of multiple preset demand states, the indoor unit currently in the preset demand state is controlled to bear the excess output of the outdoor unit, including: controlling the outdoor unit to maintain the lowest output capacity operation; in order of state priority from high to low, in each preset demand state, the indoor unit currently in the preset demand state is controlled one by one to make the refrigerant flow through the indoor unit or increase the refrigerant flow of the indoor unit, each time an indoor unit is controlled, the number of compressor starts and stops is detected within a preset time, if the number of compressor starts and stops is still greater than or equal to the preset number, the next indoor unit is controlled, and this cycle is repeated until the number of compressor starts and stops is less than the preset number or all indoor units currently in the preset demand state are bearing the excess output.

[0070] When the number of compressor starts and stops is less than the preset number, the new indoor unit will no longer be controlled to share the excess output of the outdoor unit. The outdoor unit will maintain the minimum output capacity and the indoor unit that is already bearing the excess output will also maintain the current state. Afterwards, if the user's cooling / heating demand changes (for example, a user changes the set temperature), the compressor needs to increase the frequency. For the indoor unit that is currently bearing the excess output, as long as the user has not changed its state, it will be restored to the original weak demand state. When the compressor drops to the minimum frequency, the number of compressor starts and stops will be re-determined to perform the corresponding control operation of sharing the excess output.

[0071] This embodiment controls the indoor units currently in each preset demand state one by one according to the number of compressor starts and stops in the order of state priority from high to low, which can more accurately share the excess output of the outdoor unit to avoid over-sharing and can more effectively reduce the impact on the indoor environment.

[0072] The above-mentioned multiple preset demand states may include: a first preset demand state, a second preset demand state and a third preset demand state. The state priorities from high to low are: the first preset demand state, the second preset demand state, and the third preset demand state.

[0073] The first preset demand state is: in heating mode, the indoor ambient temperature is less than the first preset temperature, in cooling mode, the indoor ambient temperature is greater than the second preset temperature, and the indoor unit is in the off state. Among them, the first preset temperature is used to determine whether heating is required. If the indoor ambient temperature is less than the first preset temperature, heating is required. The second preset temperature is used to determine whether cooling is required. If the indoor ambient temperature is greater than the second preset temperature, cooling is required. The first preset temperature and the second preset temperature can be set according to actual conditions. For example, the first preset temperature is set to 0°C and the second preset temperature is set to 30°C. In heating mode, the indoor ambient temperature is very low. Normally, the air conditioner should be turned on for heating, but in fact, the user has not turned on the indoor unit, and there may be no one indoors. At this time, it can be considered that the user's demand for the use of this indoor unit is relatively weak. Similarly, in cooling mode, the indoor ambient temperature is very high. Normally, the air conditioner should be turned on for cooling, but in fact, the user has not turned on the indoor unit, and there may be no one indoors. At this time, it can be considered that the user's demand for the use of this indoor unit is relatively weak. Using such an indoor unit to bear the excess output of the outdoor unit has the least impact on the indoor unit. When the indoor unit in the first preset demand state is turned on, its fan can be turned on to the default gear and its throttling element can be turned on to the default opening. As long as the indoor unit is turned on, the effect of bearing the excess output of the outdoor unit can be achieved.

[0074] The second preset demand state is: the difference between the indoor unit set temperature and the indoor ambient temperature in the heating mode is greater than the third preset temperature, the difference between the indoor unit set temperature and the indoor ambient temperature in the cooling mode is less than the fourth preset temperature, and the indoor unit wind speed is less than or equal to the preset wind speed. Among them, the third preset temperature is used to determine whether the heating demand is large. The difference between the indoor unit set temperature and the indoor ambient temperature in the heating mode is greater than the third preset temperature, indicating that the heating demand is large. The fourth preset temperature is used to determine whether the cooling demand is large. The difference between the indoor unit set temperature and the indoor ambient temperature in the cooling mode is less than the fourth preset temperature, indicating that the cooling demand is large. The third preset temperature and the fourth preset temperature can be set according to actual conditions. The fourth preset temperature is less than 0. For example, the third preset temperature is set to 10°C and the fourth preset temperature is set to -10°C. The preset wind speed is used to determine whether the indoor unit wind speed is low. The indoor unit wind speed is less than or equal to the preset wind speed, indicating that the indoor unit wind speed is low. The preset wind speed can be set according to actual conditions, for example, the preset wind speed is set to the medium wind speed. In this case, the indoor unit is in the on state, and refrigerant flows through the indoor unit, but because the wind gear is small, the refrigerant flow rate is also small. According to the user's set temperature, the demand is large, but according to the indoor unit wind gear state, the actual supply is small. It may be a user's operation error. Using such an indoor unit to bear the excess output of the outdoor unit has little impact on the user. When controlling the indoor unit in the second preset demand state, its fan gear can be increased, and its throttling element is opened to the opening corresponding to the fan gear.

[0075] The third preset demand state is: the difference between the indoor unit set temperature and the indoor ambient temperature in the heating mode is greater than the fifth preset temperature, the difference between the indoor unit set temperature and the indoor ambient temperature in the cooling mode is less than the sixth preset temperature, and the indoor unit is only operated by the wind gear alone. In this case, the user turns on the air supply mode, and no refrigerant flows through the indoor unit. The fifth preset temperature is used to determine whether there is a heating demand according to the air conditioning control logic. In the heating mode, the difference between the indoor unit set temperature and the indoor ambient temperature is greater than the fifth preset temperature, indicating that there is a heating demand. The sixth preset temperature is used to determine whether there is a cooling demand according to the air conditioning control logic. In the cooling mode, the difference between the indoor unit set temperature and the indoor ambient temperature is less than the sixth preset temperature, indicating that there is a cooling demand. The fifth preset temperature and the sixth preset temperature can be set according to the actual situation. For example, the fifth preset temperature is set to 0°C and the sixth preset temperature is set to 0°C. In this case, the user only turns on the indoor fan, and the corresponding indoor unit does not participate in the refrigerant circulation. If the set temperature has a negative deviation from the ambient temperature during cooling, and a positive deviation from the ambient temperature during heating, it is considered that there is an actual need to turn on the unit. However, the user turns on the air supply mode at this time, so it is considered that the user setting is wrong or the actual user does not have a need to turn on the unit. Therefore, the priority of the third preset demand state is defined as the lowest priority to reduce the impact on user use. When controlling the indoor unit in the third preset demand state, its throttling element can be opened to the opening corresponding to the current fan gear.

[0076] This embodiment sets a plurality of preset demand states through different demand states of the indoor unit, and sets state priorities, and determines the degree of influence of the indoor unit with weak demand on the indoor environment when it assumes excess output. The higher the priority, the smaller the corresponding influence. In this way, the indoor unit can be controlled step by step according to the state priority to share the excess output of the outdoor unit, thereby more effectively reducing the influence on the indoor environment.

[0077] The air conditioning control method is described below in conjunction with a specific embodiment. However, it is worth noting that the specific embodiment is only for better illustrating the present application and does not constitute an improper limitation on the present application. The explanation of terms that are the same or corresponding to the above embodiment will not be repeated in this embodiment.

[0078] refer to Figure 2 , is a schematic diagram of an air conditioner, which includes: an outdoor unit and at least two indoor units connected to the outdoor unit (such as n indoor units shown in the figure). Each indoor unit can be installed in different areas, responsible for cooling / heating in the area to which it belongs, to achieve differentiated control of different areas and different indoor units. The outdoor unit includes: a compressor 1, an oil separator 2, a four-way valve 3, an outdoor heat exchanger 4, a refrigerant heat dissipation module 5, a first throttling element 6 and a gas-liquid separator 7. Each indoor unit includes: a second throttling element 8 and an indoor heat exchanger 9.

[0079] After the air conditioner is installed, during the operation of the air conditioner, the storage unit is used to record the status information of each indoor unit as a basis for determining whether the indoor unit is in a weak demand state. Specifically, it can be detected and recorded periodically, in real time, or triggered when the indoor unit status changes. For example, the indoor ambient temperature, indoor unit on / off status, indoor unit set temperature, and indoor unit windshield status of each indoor unit in each time period are recorded. Figure 3 shown.

[0080] According to the indoor unit status information recorded above, define the indoor unit weak demand state as follows:

[0081] Indoor unit weak demand state 1: Heating T 环温 <0℃, refrigeration T 环温 >30℃, and the corresponding indoor unit is turned off (no one is present);

[0082] Indoor unit weak demand state 2: Heating T 设定 -T 环温 >10℃, cooling T 设定 -T 环温 <-10℃, and the corresponding internal machine wind speed is in the medium or low wind speed state (judgment that the demand is large but the actual supply is small);

[0083] Indoor unit weak demand state 3: The user sets the fan mode to operate independently, heating T 设定 -T 环温 >0℃, cooling T 设定 -T 环温 <0℃ (no requirement from the user but required by the machine settings).

[0084] T 环温 Indicates the indoor ambient temperature, T 设定 Indicates the indoor unit set temperature.

[0085] The priority of indoor unit weak demand state 1 is greater than the priority of indoor unit weak demand state 2 and greater than the priority of indoor unit weak demand state 3. The impact of the weak demand indoor unit on the indoor environment when it assumes excess output is determined by the different demand states of the indoor units. The higher the priority, the smaller the corresponding impact.

[0086] like Figure 4 As shown, it is an air conditioning control flow chart, which includes the following steps:

[0087] S401, the air conditioner is turned on and running.

[0088] S402, the outdoor unit operates according to the target output.

[0089] S403, determine whether the indoor ambient temperature is close to the set temperature (i.e., determine whether the indoor ambient temperature corresponding to the indoor unit that is not in the preset demand state and has been turned on is close to its corresponding set temperature). If so, enter S404; if not, return to S402 and continue to operate according to the target output.

[0090] S404, the outdoor unit is reduced to the minimum output operation, that is, the compressor operates at the lowest frequency.

[0091] S405, detecting the number of times the compressor is started and stopped.

[0092] S406, determine whether the number of compressor starts and stops is greater than or equal to the preset number X, if not, proceed to S407, if yes, proceed to S408.

[0093] S407, the outdoor unit maintains the lowest output operation.

[0094] S408: Prioritize turning on the indoor units in weak demand state 1 one by one to bear the excess output of the outdoor unit, and the outdoor unit maintains the minimum output. After turning on the indoor units in weak demand state 1, the output of the compressor is not increased, and they are only used to bear the excess output of the outdoor unit in the minimum output operation state.

[0095] Specifically, each time an indoor unit in weak demand state 1 is turned on, it is determined whether the number of compressor starts and stops is greater than or equal to the preset number. If so, the next indoor unit in weak demand state 1 is turned on. If not, no new indoor unit in weak demand state 1 is turned on, and the indoor units in weak demand state 1 that have been turned on maintain the current bearing state. When all indoor units in weak demand state 1 are turned on and the number of compressor starts and stops is still greater than or equal to the preset number, the indoor units in weak demand state 2 can be controlled one by one to participate in bearing the excess output of the outdoor unit. At this time, the indoor units in weak demand state 1 that have been turned on maintain the current bearing state.

[0096] S409, determine whether the number of compressor starts and stops is greater than or equal to the preset number, if not, proceed to S410, if yes, proceed to S411.

[0097] S410, the outdoor unit maintains the lowest output operation, and the indoor unit in weak demand state 1 that has been turned on maintains the current bearing state.

[0098] S411, control the indoor units in weak demand state 2 one by one to bear the excess output of the outdoor unit, and the outdoor unit maintains the minimum output. The controlled indoor units in weak demand state 2 will not increase the output of the compressor, and are only used to bear the excess output of the outdoor unit in the minimum output operation state.

[0099] Specifically, each time an indoor unit in weak demand state 2 is controlled, it is determined whether the number of compressor starts and stops is greater than or equal to the preset number. If so, the next indoor unit in weak demand state 2 is controlled. If not, the new indoor unit in weak demand state 2 is no longer controlled, and the indoor unit in weak demand state 2 that is already bearing excess output maintains the current bearing state. When all indoor units in weak demand state 2 are bearing excess output and the number of compressor starts and stops is still greater than or equal to the preset number, the indoor units in weak demand state 3 can be controlled one by one to participate in bearing the excess output of the outdoor unit. At this time, the indoor units in weak demand state 1 and weak demand state 2 that are already bearing excess output maintain the current bearing state.

[0100] S412, determine whether the number of compressor starts and stops is greater than or equal to the preset number, if not, proceed to S413, if yes, proceed to S414.

[0101] S413: The outdoor unit maintains the lowest output operation, and the indoor unit in weak demand state 1 and the indoor unit in weak demand state 2 that are already bearing excess output maintain their current bearing status.

[0102] S414, control the indoor units in weak demand state 3 one by one to bear the excess output of the outdoor unit, and the outdoor unit maintains the minimum output. The controlled indoor units in weak demand state 3 will not increase the output of the compressor, and are only used to bear the excess output of the outdoor unit in the minimum output operation state.

[0103] Specifically, each time an indoor unit in weak demand state 3 is controlled, it is determined whether the number of compressor start and stop times is greater than or equal to the preset number. If so, the next indoor unit in weak demand state 3 is controlled. If not, the new indoor unit in weak demand state 3 is no longer controlled, and the indoor unit in weak demand state 3 that is already bearing the excess output maintains the current bearing state.

[0104] Through auxiliary control of the indoor unit in the above weak demand state, the excess output of the outdoor unit when it is running at the minimum output capacity can be borne, the frequent start and stop of the compressor can be improved, the volatility during the operation of the air conditioner can be reduced, and the continuous operation of the air conditioner can be achieved. This solves the problem in the prior art that the minimum output of the air conditioner does not match the actual user demand, resulting in frequent start and stop of the compressor, improves the reliability and comfort of the air conditioner operation, increases the selection redundancy, and broadens the adaptability of the product use.

[0105] Adding weak demand indoor units or increasing the refrigerant flow of weak demand indoor units will affect the evaporation pressure or condensation pressure during air conditioning operation. The condensation pressure and evaporation pressure can indirectly represent the heat exchange effect during air conditioning operation, and reduce the output quality on the demand side to indirectly affect the heat exchange quality on the demand side. For example, when cooling, adding weak demand indoor units or increasing the refrigerant flow of weak demand indoor units will increase the evaporation pressure and the outlet air temperature on the demand side, which means that the output quality on the demand side is reduced.
