[0044] In order to make the features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the embodiments of the present application.

[0045] In the description of the present application, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood in specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B, which can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are an "or" relationship.

[0046] In the related art, in low temperature environments, some auxiliary heating equipment is usually added to be used together with the heat pump air conditioner to make up for the problem of insufficient performance of the heat pump air conditioner in low temperature environments. When the heat pump air conditioner is equipped with an auxiliary heating device, the auxiliary heating device is usually started first in a low temperature environment to ensure that the pipes and other components of the heat pump air conditioner are not frozen. However, since the auxiliary heating device is usually a third-party device, the air conditioner cannot detect the signal whether the auxiliary heating device is in a normal working state.

[0047] In order to solve the related technical problems, the embodiment of the present application provides a control method for an air-conditioning system, which air-conditioning system includes an air conditioner and an auxiliary heating device, the auxiliary heating device is used to heat the liquid in the circulating water circuit of the air conditioner, when the ambient temperature is less than or equal to the first preset temperature, and the first current water temperature value corresponding to the target water temperature parameter in the circulating water circuit is less than or equal to the second preset temperature, the auxiliary heating device is turned on based on the air conditioner control, when the auxiliary heating device is turned on and when the auxiliary heating device is turned on for a preset time, the second current water temperature value and the third current water temperature value corresponding to the target water temperature parameter are respectively obtained, and when the auxiliary heating device is turned on for a preset time, the third current water temperature value corresponding to the target water temperature parameter is turned on for a preset time. When the previous water temperature value is less than or equal to the second current water temperature value when the auxiliary heating equipment is turned on, it indicates that the auxiliary heating equipment is in an abnormal working state. At this time, the local antifreeze operation mode is turned on based on the air conditioner to prevent the liquid in the circulating water circuit from freezing into ice due to the low ambient temperature. Even if the air conditioner cannot detect the signal whether the auxiliary heating equipment is in a normal working state, the working state of the auxiliary heating equipment can be determined based on the change of the water temperature value corresponding to the target water temperature parameter, and then the corresponding antifreeze response strategy can be adopted, thereby solving the technical problem that the configuration compatibility between the air conditioner and the third-party heating equipment is often low, making it difficult for the air conditioner to cooperate with the third-party heating equipment to effectively deal with low temperatures for antifreeze treatment.

[0048] See also Figure 1 , Figure 1 This is a simplified schematic diagram of the structure of an air conditioning system provided in an embodiment of the present application. Figure 1 As shown, the air conditioning system 1000 includes an air conditioner 1100 and an auxiliary heating device 1200, wherein the auxiliary heating device 1200 is used to heat the liquid in the circulating water circuit of the air conditioner 1100. The air conditioner 1100 may be a heat pump air conditioner with a local antifreeze operation mode. The air conditioner 1100 in this embodiment may control the auxiliary heating device 1200 to be turned on or off.

[0049] The basic structure of the air conditioner 1100 in this embodiment includes a compressor, a four-way valve, an air-side heat exchange component, a water-side heat exchange component, a throttling component, a circulating water pump, an outdoor temperature sensing element, and a water-side temperature sensing element, which are similar to the structure of an ordinary heat pump air conditioner, so no further details are given here. Among them, the compressor is used to suck, compress and transport the refrigerant; the four-way valve is used to realize the conversion between the two working modes of the air conditioner, namely, cooling and heating; the air-side heat exchange component is used to transfer the heat in the air to the medium in the air-side heat exchange component or to recover the heat from the medium in the air-side heat exchange component; the water-side heat exchange component is used to use water as a heat transfer medium, and realize the cooling or heating function of the air conditioner through the heat exchange between water and the refrigerant; the throttling component is used to adjust the flow rate and pressure of the refrigerant; the circulating water pump is used to drive the liquid in the circulating water circuit of the air conditioner to flow; the outdoor temperature sensing element is used to monitor the ambient temperature; and the water-side temperature sensing element is used to monitor the water inlet temperature value and the water outlet temperature value of the water-side heat exchange component.

[0050] See also Figure 2 , Figure 2 1 is a flow chart of a control method for an air conditioning system provided in an embodiment of the present application. The execution subject of the control method for the air conditioning system may be the air conditioner 1100 or a controller in the air conditioner 1100. Figure 2 As shown, the control method of the air conditioning system includes:

[0051] S202: Acquire the ambient temperature, determine that the ambient temperature is less than or equal to a first preset temperature, and when a first current water temperature value corresponding to a target water temperature parameter in the circulating water circuit is less than or equal to a second preset temperature, turn on the auxiliary heating device based on the air conditioner control.

[0052] The ambient temperature is monitored by the outdoor temperature sensing element in the air conditioner 1100, so as to obtain the ambient temperature. After determining the ambient temperature, the first preset temperature is obtained, and the ambient temperature is compared with the first preset temperature to determine whether the current ambient temperature has a risk of freezing the pipe components in the air conditioner 1100. Specifically, the first preset temperature may be 0°C. Of course, the first preset temperature may also be other preset temperatures, which may be higher or lower than 0°C, and there is no limitation here.

[0053] When it is determined that the ambient temperature is less than or equal to the first preset temperature, the second preset temperature is obtained, and the first current water temperature value corresponding to the target water temperature parameter in the circulating water circuit is compared with the second preset temperature to determine whether there is a risk of water freezing in the circulating water circuit. Specifically, the second preset temperature can be 3 to 5°C, and the second preset temperature is usually greater than the first preset temperature. It should be noted that the water temperature value corresponding to the target water temperature parameter in the circulating water circuit is the smaller value of the current water inlet water temperature value and the current water outlet water temperature value in the water side heat exchange component.

[0054] When it is determined that the ambient temperature is less than or equal to the first preset temperature, and the first current water temperature value corresponding to the target water temperature parameter in the circulating water circuit is less than or equal to the second preset temperature, it indicates that there is a risk of freezing of components such as the pipeline in the air conditioner 1100 due to the low ambient temperature. Therefore, at this time, the air conditioner 1100 can be used to control the auxiliary heating device 1200 to heat the liquid in the circulating water circuit of the air conditioner 1100. Specifically, the auxiliary heating device 1200 can be powered on based on the air conditioner 1100 to turn on the auxiliary heating device 1200. The auxiliary heating device 1200 can be connected to the corresponding pipeline of the circulating water circuit of the air conditioner 1100, so as to heat the liquid in the circulating water circuit of the air conditioner 1100 by heating the corresponding pipeline of the circulating water circuit. It is easy to understand that when the auxiliary heating device 1200 is turned on, in order to quickly heat the liquid in the circulating water circuit, the circulating water pump can be controlled based on the air conditioner 1100 to drive the liquid in the circulating water circuit to flow.

[0055] In addition, after the auxiliary heating device 1200 is turned on based on the control of the air conditioner 1100, in another embodiment provided by the present application, when it is determined that the current water temperature value corresponding to the target water temperature parameter in the circulating water circuit is greater than the third preset temperature, the auxiliary heating device 1200 is turned off; wherein the third preset temperature is greater than the second preset temperature. In order to avoid frequent start and stop of the auxiliary heating device 1200, the third preset temperature is set to be greater than the second preset temperature, so that after the current water temperature value corresponding to the target water temperature parameter is greater than the third preset temperature, even if the water temperature does not immediately drop to the second preset temperature due to a drop, the auxiliary heating device 1200 is frequently started and stopped in a short period of time.

[0056] S204: Obtain a second current water temperature value corresponding to the target water temperature parameter when the auxiliary heating device is turned on, and when the auxiliary heating device is turned on for a preset time, obtain a third current water temperature value corresponding to the target water temperature parameter.

[0057] Among them, it is usually necessary to wait for a certain interval of time to turn on the auxiliary heating device 1200, so the real-time water temperature value corresponding to the target water temperature parameter when the auxiliary heating device 1200 is turned on will change compared to the first current water temperature value. Therefore, in order to accurately determine the water temperature value of the target water temperature parameter at this time, the second current water temperature value corresponding to the target water temperature parameter when the auxiliary heating device 1200 is turned on can be obtained. At the same time, the air conditioner 1100 counts when the auxiliary heating device 1200 is turned on. When the turning-on time of the auxiliary heating device 1200 reaches the preset time, the third current water temperature value corresponding to the target water temperature parameter at this time is obtained. Specifically, the preset time here can be 5 minutes. Of course, the preset time can also be pre-set to other time according to the actual scene requirements, and there is no restriction here.

[0058] It is easy to understand that when the auxiliary heating device 1200 operates normally, after the auxiliary heating device 1200 is turned on for a preset time, the third current water temperature value corresponding to the target water temperature parameter will usually be greater than the second current water temperature value corresponding to the target water temperature parameter when the auxiliary heating device 1200 is turned on.

[0059] S206: When it is determined that the third current water temperature value is less than or equal to the second current water temperature value, start the local antifreeze operation mode based on the air conditioner.

[0060] Among them, when the third current water temperature value is less than or equal to the second current water temperature value, it indicates that the auxiliary heating device 1200 is in an abnormal working state, that is, the auxiliary heating device 1200 is in a state of insufficient heating or is unable to provide heating.

[0061] At this time, the local antifreeze operation mode can be turned on based on the air conditioner 1100, so that the circulating water pump in the air conditioner 1100 can be used to drive the liquid in the circulating water circuit to flow, and the heating component in the air conditioner 1100 can be used to heat the liquid in the circulating water circuit, so as to prevent the liquid in the circulating water circuit from freezing into ice due to the low ambient temperature.

[0062] In the embodiment provided in the present application, when the ambient temperature is less than or equal to the first preset temperature, and the first current water temperature value corresponding to the target water temperature parameter in the circulating water circuit is less than or equal to the second preset temperature, the auxiliary heating device 1200 is turned on based on the air conditioner 1100 control. When the auxiliary heating device 1200 is turned on and when the on-time of the auxiliary heating device 1200 reaches the preset time, the second current water temperature value and the third current water temperature value corresponding to the target water temperature parameter are respectively obtained. When the on-time of the auxiliary heating device 1200 reaches the preset time, the corresponding third current water temperature value is less than or equal to the second current water temperature value when the auxiliary heating device 1200 is turned on, indicating that The auxiliary heating device 1200 is in an abnormal working state. At this time, the local antifreeze operation mode is turned on based on the air conditioner 1100 to prevent the liquid in the circulating water circuit from freezing into ice due to the low ambient temperature. Even if the air conditioner 1100 cannot detect the signal whether the auxiliary heating device 1200 is in a normal working state, the working state of the auxiliary heating device 1200 can be determined based on the change of the water temperature value corresponding to the target water temperature parameter, and then the corresponding antifreeze response strategy can be adopted, thereby solving the technical problem that the configuration compatibility between the air conditioner and the third-party heating device is often low, making it difficult for the air conditioner to cooperate with the third-party heating device to effectively deal with low temperatures for antifreeze treatment.

[0063] See also Figure 3 , Figure 3 A schematic diagram of a process for determining that an auxiliary heating device is in an abnormal working state is provided in an embodiment of the present application. Figure 3As shown, after the auxiliary heating device is turned on based on the air conditioner control in S202, the method further includes:

[0064] S302: Determine the current water temperature value of the target water temperature parameter and the heating power of the auxiliary heating device.

[0065] Among them, since the auxiliary heating device 1200 is a third-party heating device, it is usually difficult for the air conditioner 1100 to directly obtain the heating power of the auxiliary heating device 1200. Therefore, after the auxiliary heating device 1200 is determined, the heating power of the auxiliary heating device 1200 can be manually input into the air conditioner 1100. Specifically, the heating power of the auxiliary heating device 1200 can be set by the air conditioner 1100 control software on the terminal paired with the air conditioner 1100, so that the heating power of the auxiliary heating device 1200 is input into the air conditioner 1100; or, the heating power of the auxiliary heating device 1200 can also be input into the air conditioner 1100 based on the physical or virtual button on the air conditioner 1100. At the same time, the current water temperature value of the target water temperature parameter is determined based on the water-side temperature sensing element in the air conditioner 1100.

[0066] S304: Obtain a target mapping relationship, and determine a normal water temperature increase rate interval corresponding to the ambient temperature, the current water temperature value, and the heating power based on the target mapping relationship.

[0067] The target mapping relationship is a mapping relationship for mapping the ambient temperature, the current water temperature value and the heating power to the corresponding normal water temperature increase rate interval. The normal water temperature increase rate interval is a normal water temperature increase rate interval under the corresponding ambient temperature, the current water temperature value and the heating power.

[0068] Specifically, the target mapping formula corresponding to the target mapping relationship can be determined by pre-simulation test or actual test. After the ambient temperature, current water temperature value and heating power are determined, the ambient temperature, current water temperature value and heating power are input into the target mapping formula, and the normal water temperature increase rate range corresponding to the ambient temperature, current water temperature value and heating power is determined based on the target mapping formula.

[0069] Of course, the target mapping table corresponding to the target mapping relationship can also be determined by pre-simulation test or actual test. After the ambient temperature, current water temperature value and heating power are determined, the target mapping table is queried based on the ambient temperature, current water temperature value and heating power, and the normal water temperature increase rate interval corresponding to the ambient temperature, current water temperature value and heating power is determined based on the target mapping table. Here, the normal water temperature increase rate interval may include the interval endpoints.

[0070] S306: Determine the current water temperature increase rate corresponding to the target water temperature parameter, and judge whether the current water temperature increase rate is within the normal water temperature increase rate interval. If the current water temperature increase rate is not within the normal water temperature increase rate interval, determine that the auxiliary heating device is in an abnormal working state.

[0071] Among them, since the current water temperature value corresponding to the target water temperature parameter will change with time, the change value of the current water temperature value in the corresponding unit time can be calculated to determine the current water temperature increase rate corresponding to the target water temperature parameter. Specifically, the current water temperature increase rate can be determined by calculating the slope of the curve corresponding to the current time point through the change interval of the current water temperature value corresponding to the target water temperature parameter over time. It is easy to understand that when the current water temperature increase rate is a positive value, it indicates that the current water temperature value corresponding to the target water temperature parameter is increasing; when the current water temperature increase rate is a negative value, it indicates that the current water temperature value corresponding to the target water temperature parameter is decreasing; when the current water temperature increase rate is 0, it indicates that the current water temperature value corresponding to the target water temperature parameter has not changed.

[0072] After determining the current water temperature increase rate corresponding to the target water temperature parameter, determine whether the current water temperature increase rate is within the normal water temperature increase rate interval. When the current water temperature increase rate is within the normal water temperature increase rate interval, it indicates that the current water temperature increase rate corresponding to the target water temperature parameter is normal, and the auxiliary heating device 1200 is determined to be in a normal working state; when the current water temperature increase rate is not within the normal water temperature increase rate interval, it indicates that the current water temperature increase rate corresponding to the target water temperature parameter is abnormal, and the auxiliary heating device 1200 is determined to be in an abnormal working state.

[0073] In the embodiment provided in the present application, the normal water temperature increase rate interval corresponding to the ambient temperature, the current water temperature value and the heating power is determined through the target mapping relationship, and then the current water temperature increase rate corresponding to the target water temperature parameter is calculated. By judging whether the current water temperature increase rate is within the normal water temperature increase rate interval, it is determined whether the auxiliary heating device 1200 is in an abnormal working state. If it is determined that the current water temperature increase rate is not within the normal water temperature increase rate interval, it indicates that the auxiliary heating device 1200 is in an abnormal working state; if it is determined that the current water temperature increase rate is within the normal water temperature increase rate interval, it indicates that the auxiliary heating device 1200 is in a normal working state.

[0074] See also Figure 4 , Figure 4 Another flow chart of determining whether the auxiliary heating device is in an abnormal working state is provided in an embodiment of the present application. Figure 4 As shown,

[0075] S402: Determine the current water temperature increase rate corresponding to the target water temperature parameter, and judge whether the current water temperature increase rate is within a normal water temperature increase rate range.

[0076] The relevant description of S402 can refer to the relevant description of S306, which will not be repeated here.

[0077] In S306, if the current water temperature increase rate is not within the normal water temperature increase rate range, it is determined that the auxiliary heating device is in an abnormal working state, including:

[0078] S404: If the current water temperature increase rate is greater than the upper limit of the interval corresponding to the normal water temperature increase rate interval, it is determined that the working abnormality type of the working abnormal state is the first abnormality type.

[0079] Among them, when the current water temperature increase rate is greater than the upper limit of the interval corresponding to the normal water temperature increase rate interval, it indicates that the heating power of the auxiliary heating device 1200 is greater than its corresponding normal heating power. At this time, the heating power of the auxiliary heating device 1200 may be too large due to voltage fluctuations, or the internal components of the auxiliary heating device 1200 may fail, resulting in the heating power of the auxiliary heating device 1200 being too large. At this time, the working abnormality type corresponding to the working abnormal state of the auxiliary heating device 1200 is the first abnormality type. If the auxiliary heating device 1200 continues to be in the working abnormal state corresponding to the first abnormality type, it may cause the auxiliary heating device 1200 to burn out.

[0080] S406: If the current water temperature increase rate is less than the interval lower limit value corresponding to the normal water temperature increase rate interval, it is determined that the working abnormality type of the working abnormal state is the second abnormality type.

[0081] Among them, when the current water temperature increase rate is less than the lower limit of the interval corresponding to the normal water temperature increase rate interval, it indicates that the heating power of the auxiliary heating device 1200 is less than its corresponding normal heating power. At this time, the actual heating power output by the auxiliary heating device 1200 may be less than its corresponding normal heating power due to the presence of additional attachments on the surface of the auxiliary heating device 1200; or the actual heating power output by the auxiliary heating device 1200 is less than its corresponding normal heating power due to the aging of the auxiliary heating device 1200; of course, the auxiliary heating device 1200 may be damaged and unable to provide heat. At this time, the working abnormality type corresponding to the abnormal working state of the auxiliary heating device 1200 is the second abnormal type. If the auxiliary heating device 1200 continues to be in the working abnormal state corresponding to the second abnormal type, it may cause the pipes and other components of the air conditioner 1100 to be frozen.

[0082] In the embodiment provided in the present application, if the current water temperature increase rate is greater than the upper limit value of the interval corresponding to the normal water temperature increase rate interval, the working abnormality type of the working abnormal state is determined to be the first abnormality type. If the auxiliary heating device 1200 continues to be in the working abnormality state corresponding to the first abnormality type, it may cause the auxiliary heating device 1200 to burn out; if the current water temperature increase rate is less than the lower limit value of the interval corresponding to the normal water temperature increase rate interval, the working abnormality type of the working abnormal state is determined to be the second abnormality type. If the auxiliary heating device 1200 continues to be in the working abnormality state corresponding to the second abnormality type, it may cause the pipes and other components of the air conditioner 1100 to be frozen.

[0083] Exemplarily, when it is determined that the abnormal working type of the abnormal working state is the second abnormal type, a local antifreeze operation mode is started based on the air conditioner;

[0084] When it is determined that the operation abnormality type of the operation abnormality state is the first abnormality type, the auxiliary heating device is turned off based on the air conditioner control, and the local antifreeze operation mode is turned on based on the air conditioner.

[0085] Among them, since the auxiliary heating device 1200 is continuously in the abnormal working state corresponding to the second abnormal type, the pipes and other components of the air conditioner 1100 may be frozen. Therefore, at this time, the local antifreeze operation mode can be turned on based on the air conditioner 1100, so as to cooperate with the circulating water pump in the air conditioner 1100 to drive the liquid in the circulating water circuit to flow, and use the heating component in the air conditioner 1100 to heat the liquid in the circulating water circuit to prevent the pipes and other components of the air conditioner 1100 from being frozen.

[0086] Since the auxiliary heating device 1200 is continuously in the abnormal working state corresponding to the first abnormal type, the auxiliary heating device 1200 may be burned. Therefore, at this time, the auxiliary heating device 1200 can be turned off based on the control of the air conditioner 1100 to avoid the auxiliary heating device 1200 from being burned, and the local antifreeze operation mode can be turned on based on the air conditioner 1100, so as to additionally cooperate with the circulating water pump in the air conditioner 1100 to drive the liquid in the circulating water circuit to flow, and use the heating component in the air conditioner 1100 to heat the liquid in the circulating water circuit to avoid the pipes and other components of the air conditioner 1100 from being frozen.

[0087] In the embodiment provided by the present application, when it is determined that the working abnormality type of the working abnormal state is the second abnormality type, if the auxiliary heating device 1200 is continuously in the working abnormality corresponding to the second abnormality type, it may cause the pipes and other components of the air conditioner 1100 to be frozen, and therefore the local antifreeze operation mode is turned on based on the air conditioner 1100; when it is determined that the working abnormality type of the working abnormal state is the first abnormality type, if the auxiliary heating device 1200 is continuously in the working abnormality corresponding to the first abnormality type, it may cause the auxiliary heating device 1200 to burn out, and therefore the auxiliary heating device 1200 is turned off based on the air conditioner 1100 control, and the local antifreeze operation mode is turned on based on the air conditioner 1100.

[0088] See also Figure 5 , Figure 5 A flow chart of a method for starting a local antifreeze operation mode of an air conditioner is provided in an embodiment of the present application. Figure 5 As shown, in S206, starting the local antifreeze operation mode based on the air conditioner includes:

[0089] S502: Generate a local antifreeze operation mode start signal, and control the air conditioner to start the local antifreeze operation mode based on the local antifreeze operation mode start signal.

[0090] Among them, when it is determined that the ambient temperature is less than or equal to the first preset temperature, and the first current water temperature value corresponding to the target water temperature parameter in the circulating water circuit is less than or equal to the second preset temperature, the auxiliary heating device 1200 is turned on based on the air conditioner 1100 control, and the second current water temperature value corresponding to the target water temperature parameter when the auxiliary heating device 1200 is turned on is obtained. When the turning-on time of the auxiliary heating device 1200 reaches the preset time, the third current water temperature value corresponding to the target water temperature parameter is obtained. When it is determined that the third current water temperature value is less than or equal to the second current water temperature value, the air conditioner 1100 generates a local antifreeze operation mode start signal, and then the air conditioner 1100 controls the air conditioner 1100 to turn on the local antifreeze operation mode based on the local antifreeze operation mode start signal.

[0091] S504: In the local antifreeze operation mode, the circulating water pump in the air conditioner drives the liquid in the circulating water circuit to flow, and the heating component in the air conditioner heats the liquid in the circulating water circuit.

[0092] Among them, when the air conditioner 1100 is in the local antifreeze operation mode, the circulating water pump in the air conditioner 1100 is used to drive the liquid in the circulating water circuit to flow. During the flow of the liquid, there is convection inside the liquid. Convection will accelerate the transfer and distribution of heat, so that the heat in the liquid is more evenly distributed, reducing the area where the local temperature is too low. In addition, in the flowing liquid, the arrangement of water molecules is constantly disrupted, making it difficult to form a stable ice crystal structure. At the same time, when the liquid flows, the interaction and collision between its molecules will increase, which slows down the freezing process to a certain extent. At the same time, when the circulating water pump drives the liquid in the circulating water circuit to flow, the heating component in the air conditioner 1100 is used to heat the liquid in the circulating water circuit, thereby increasing the current water temperature value of the target water temperature parameter, thereby preventing the pipes and other components of the air conditioner 1100 from being frozen.

[0093] In the embodiment provided in the present application, when the air conditioner 1100 is in the local antifreeze operation mode, the circulating water pump in the air conditioner 1100 is used to drive the liquid in the circulating water circuit to flow, and when the circulating water pump is used to drive the liquid in the circulating water circuit to flow, the heating component in the air conditioner 1100 is used to heat the liquid in the circulating water circuit, thereby increasing the current water temperature value of the target water temperature parameter, thereby preventing the pipes and other components of the air conditioner 1100 from being damaged by freezing.

[0094] See also Figure 6 , Figure 6 A schematic diagram of a process for updating the current water temperature value corresponding to the target water temperature parameter provided in an embodiment of the present application. The air conditioner 1100 includes a water side heat exchange component, the water side heat exchange component includes a water inlet and a water outlet, and the water inlet and the water outlet are located on the circulating water path. Figure 6 As shown, the method includes:

[0095] S602: Determine a current water temperature value of the water inlet corresponding to the water inlet, and a current water temperature value of the water outlet corresponding to the water outlet.

[0096] The water side temperature sensing element corresponding to the water inlet monitors the current water temperature value at the water inlet, and the water side temperature sensing element corresponding to the water outlet monitors the current water temperature value at the water outlet. The water side temperature sensing element can respond to water temperature changes in real time and convert them into electrical signals for transmission and processing, thereby obtaining the corresponding water temperature value.

[0097] S604: Compare the current water temperature value of the water inlet and the current water temperature value of the water outlet to determine the smaller target water temperature value between the current water temperature value of the water inlet and the current water temperature value of the water outlet.

[0098] After determining the current water inlet water temperature value and the current water outlet water temperature value, the current water inlet water temperature value and the current water outlet water temperature value are compared to obtain the smaller target water temperature value between the current water inlet water temperature value and the current water outlet water temperature value.

[0099] When the current water inlet water temperature value is greater than the current water outlet water temperature value, the current water outlet water temperature value is the target water temperature value; when the current water inlet water temperature value is less than the current water outlet water temperature value, the current water inlet water temperature value is the target water temperature value; when the current water inlet water temperature value is equal to the current water outlet water temperature value, any one of the current water inlet water temperature value and the current water outlet water temperature value can be used as the target water temperature value.

[0100] S606: Based on the target water temperature value, the current water temperature value corresponding to the target water temperature parameter in the circulating water circuit is updated.

[0101] Among them, after determining the target water temperature value, the target water temperature value is used to update the current water temperature value corresponding to the target water temperature parameter in the circulating water circuit to cover the historical water temperature value corresponding to the target water temperature parameter. It should be noted that the updating process of the current water temperature value corresponding to the target water temperature parameter in the circulating water circuit can be carried out continuously, or it can be updated at intervals of a period of time, such as every 1s, 5s, 10s, etc., and the interval time here is not limited.

[0102] In the embodiment provided in the present application, by determining the current water inlet water temperature value corresponding to the water inlet and the current water outlet water temperature value corresponding to the water outlet, the current water inlet water temperature value and the current water outlet water temperature value are compared to determine the smaller target water temperature value between the current water inlet water temperature value and the current water outlet water temperature value, thereby updating the current water temperature value corresponding to the target water temperature parameter in the circulating water circuit based on the target water temperature value, so that the current water temperature value corresponding to the target water temperature parameter is more accurate, thereby accurately controlling the control operation of the air-conditioning system 1000 on the auxiliary heating equipment 1200.
