The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0044] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0045] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0046] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0048] The inventors also discovered through research that the relevant technology cannot automatically and intelligently enter or exit the heat storage and defrosting mode according to the actual usage.

[0049] In view of at least one of the above-mentioned technical problems, this disclosure provides an air conditioner and its control method and apparatus, storage medium and program product. The disclosure will now be described through specific embodiments.

[0050] Figure 1 This is a schematic diagram of some embodiments of the air conditioning control method disclosed herein. Figure 1 This is a schematic diagram of the heat storage entry or exit condition control method in some embodiments of this disclosure. Figure 1 The embodiments can be executed by the air conditioner or air conditioner control device of this disclosure. For example... Figure 1 As shown, Figure 1 The method of the embodiment may include at least one of steps 100 to 200.

[0051] In step 100, the cumulative heat storage time of the accumulator in the air conditioner and the water temperature inside the accumulator are obtained.

[0052] In some embodiments of this disclosure, the air conditioner may be an energy storage air conditioner.

[0053] In some embodiments of this disclosure, the air conditioner may be a multi-split air conditioner, an energy-saving multi-split air conditioner, an energy-saving air conditioner, an energy-saving refrigeration and air conditioning equipment, etc.

[0054] In some embodiments of this disclosure, the timing mechanism for the accumulated heat storage time is as follows: when the unit starts the heat storage mode, the system will automatically start recording the heat storage duration. The timing rules may include: when the heat release defrosting mode is started, the timer is automatically reset to zero; if the unit enters other operating modes such as normal heating or normal defrosting after the heat storage is completed, the timer remains unchanged and the timer pauses; when the unit re-enters the heat storage mode, the timer will continue to accumulate the previous heat storage duration.

[0055] In step 200, based on the cumulative heat storage time and the water temperature inside the heat storage unit, it is determined whether the air conditioner has entered or exited the heat storage mode.

[0056] In some embodiments of this disclosure, the heat storage mode refers to the operating state of an air conditioner with energy storage function, which stores excess heat through an energy storage device.

[0057] The embodiments of this disclosure achieve optimal heat storage configuration through precise setting of entry and exit conditions for the heat storage mode. These embodiments ensure sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste caused by excessive heat storage, thus achieving efficient energy utilization while guaranteeing defrosting effectiveness and improving the energy-saving performance of the heat storage air conditioner.

[0058] In some embodiments of this disclosure, step 200 may include at least one of steps 210 to 220.

[0059] In step 210, if the air conditioner is currently in heat storage mode, it is determined whether the air conditioner should exit the heat storage mode based on the cumulative heat storage time and the water temperature in the heat storage tank.

[0060] In some embodiments of this disclosure, step 210 may include at least one of steps 211 to 213.

[0061] In step 211, when the cumulative heat storage time is less than or equal to the time threshold t c Furthermore, the water temperature inside the heat storage device is lower than or equal to the first temperature threshold T. max In the event that the energy storage capacity of the accumulator has not yet reached full capacity, the air conditioner is controlled to maintain the heat storage mode.

[0062] In some embodiments of this disclosure, the time threshold t c The time reference required for the accumulator to reach full-load heat storage state is preset for the system. This parameter can be determined through actual experimental testing and pre-programmed into the unit control system.

[0063] In some embodiments of this disclosure, the time threshold t c A typical value is 3 hours, which can be adjusted and optimized according to specific application scenarios and device characteristics.

[0064] In some embodiments of this disclosure, the first temperature threshold T max The artificially set thermal storage termination temperature threshold can be determined through experimental testing and preset in the unit control program.

[0065] In some embodiments of this disclosure, the first temperature threshold T max The recommended temperature is 35℃.

[0066] In step 212, if the cumulative heat storage time is less than or equal to the time threshold and the water temperature in the heat storage device is higher than the first temperature threshold, it is determined that the heat storage device has reached the full load heat storage state, and the air conditioner is controlled to automatically exit the heat storage mode.

[0067] The embodiments disclosed above use both heat storage accumulation time and water temperature as conditions for entering and exiting the heat storage mode. This allows for precise setting of the heat storage mode entry and exit criteria, achieving optimal heat storage capacity. If only heat storage accumulation time is used, the water temperature after the final heat storage period may be significantly higher than the first temperature threshold T. max The above-described embodiments of this disclosure add temperature judgment conditions, which may actually end heat storage earlier, thereby avoiding energy waste.

[0068] In step 213, if the cumulative heat storage time exceeds a time threshold, the air conditioner is controlled to automatically exit the heat storage mode.

[0069] In the above embodiments of this disclosure, when the cumulative heat storage time reaches a preset time threshold t c When this happens, the system will automatically end the current heat storage process and exit the heat storage mode.

[0070] In step 220, if the air conditioner is not currently in heat storage mode, it is determined whether the air conditioner has entered heat storage mode based on the cumulative heat storage time and the water temperature in the heat storage tank.

[0071] In some embodiments of this disclosure, the air conditioner not currently in heat storage mode includes the air conditioner currently in non-heat storage mode or in a powered-off state.

[0072] The embodiments of this disclosure use the current state of heat storage mode, the cumulative heat storage time, and the water temperature as conditions for entering and exiting the heat storage mode. Therefore, the embodiments of this disclosure can achieve optimal configuration of heat storage capacity through precise setting of heat storage mode entry or exit conditions. The embodiments of this disclosure can ensure sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste caused by excessive heat storage, thus achieving efficient energy utilization while ensuring defrosting effectiveness.

[0073] In some embodiments of this disclosure, step 220 may include at least one of steps 221 to 223.

[0074] In step 221, when the cumulative heat storage time is less than or equal to a time threshold and the water temperature inside the heat storage device is lower than or equal to a second temperature threshold T... min In the event that the heat reserve in the energy storage device is insufficient, the air conditioner is controlled to start the heat storage mode, wherein the second temperature threshold T min Less than the first temperature threshold T max .

[0075] In some embodiments of this disclosure, the second temperature threshold T min The temperature threshold set manually can be determined through experimental testing and then fixed in the unit control program.

[0076] In some embodiments of this disclosure, the second temperature threshold T min The recommended value is 25℃, but this parameter can be adjusted appropriately according to actual operating conditions and equipment characteristics.

[0077] In step 222, if the cumulative heat storage time is less than or equal to the time threshold and the water temperature in the heat storage device is higher than the second temperature threshold, it is determined that there is still sufficient heat in the heat storage device, and the air conditioner is controlled not to start the heat storage mode. The time threshold can be the maximum cumulative heat storage time corresponding to the maximum heat storage capacity of the heat storage device.

[0078] The embodiments of this disclosure use both accumulated heat storage time and water temperature as conditions for entering and exiting the heat storage mode. This allows for precise setting of the entry and exit conditions, enabling optimal configuration of the heat storage capacity. If only temperature is used as the entry and exit condition in the embodiments of this disclosure, and the accumulator temperature drops below the second temperature threshold T during a prolonged unit shutdown... min The unit will start heat storage again when the time comes, and without a judgment on the cumulative heat storage time, there may be repeated heat storage situations.

[0079] The embodiments disclosed above use both heat storage accumulation time and water temperature as entry and exit conditions for the heat storage mode, and the water temperature threshold for the entry condition of the heat storage mode and the water temperature threshold for the exit condition of the heat storage mode are not equal.

[0080] The embodiments disclosed above set a first temperature threshold T. max With the second temperature threshold T min The main purpose of unequal values ​​is to avoid frequent system start-ups and shutdowns. If the two values ​​are the same, the following situation may occur: the heat storage mode has just reached the first temperature threshold T. max However, the water temperature may drop slightly below the second temperature threshold T due to factors such as natural heat loss. minAt this point, the system will immediately restart heat storage, causing unnecessary cycles. By maintaining the first temperature threshold T... max Second temperature threshold T min The difference provides a reasonable temperature tolerance range for the system, effectively preventing this oscillation phenomenon.

[0081] In step 223, if the cumulative heat storage time exceeds the time threshold, the air conditioner is not currently in heat storage mode, so the air conditioner is controlled not to start the heat storage mode.

[0082] Figure 2 This is a schematic diagram of some other embodiments of the air conditioning control method disclosed herein. Figure 2 This is a schematic diagram of the heat storage entry or exit condition control method in some other embodiments of this disclosure. Figure 2 The embodiments can be executed by the air conditioner or air conditioner control device of this disclosure. For example... Figure 2 As shown, Figure 2 The method of the embodiment may include at least one of steps 80 to 90 and steps 100 to 200. Figure 2 Steps 100 to 200 of the embodiment are respectively with Figure 1 Steps 100 to 200 in the embodiment are the same or similar.

[0083] In step 80, the weather conditions for a future predetermined time period are obtained.

[0084] In some embodiments of this disclosure, the weather conditions include average relative humidity and average outdoor temperature.

[0085] In some embodiments of this disclosure, step 80 may include: obtaining the average relative humidity for a future predetermined time period and the average outdoor temperature for the future predetermined time period based on weather linkage.

[0086] In some embodiments of this disclosure, the future scheduled time can be several hours, with 4 hours being recommended.

[0087] In step 90, at least one of the time threshold, the first temperature threshold, and the second temperature threshold is modified according to the weather conditions.

[0088] The embodiments of this disclosure can set different time thresholds, the first temperature threshold, and the second temperature threshold under different weather conditions. Therefore, these embodiments can more accurately achieve optimal configuration of heat storage under various climatic conditions. This ensures sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste due to excessive heat storage, thus achieving efficient energy utilization while guaranteeing defrosting effectiveness. The embodiments of this disclosure can determine the optimal timing for heat storage entry and exit under various weather conditions, thereby improving the energy-saving effect of heat storage air conditioning under diverse weather conditions.

[0089] In some embodiments of this disclosure, step 90 may include at least one of steps 91 to 92.

[0090] In step 91, the frost tendency level is predicted based on the average relative humidity and the average outdoor temperature.

[0091] In some embodiments of this disclosure, step 91 may include at least one of steps 911 to 914.

[0092] In step 911, the relative humidity is pre-divided into multiple relative humidity ranges.

[0093] In some embodiments of this disclosure, step 911 may include: dividing the relative humidity into three relative humidity intervals using two relative humidity thresholds N and M. That is, [0, N%), [N%, M%), [M%, 100%), where 0 < N < M < 100%.

[0094] In some embodiments of this disclosure, the recommended values ​​for M and N are 60 and 30, respectively.

[0095] In step 912, the outdoor temperature is pre-divided into multiple outdoor temperature ranges.

[0096] In some embodiments of this disclosure, step 912 may include: dividing the outdoor temperature into four outdoor intervals using three outdoor temperature thresholds L, K, and J. That is, [T1, L℃), [L℃, K℃), [K℃, J℃), [J℃, T2), where T1 < L < K < J < T2, T1 is the lower limit of the outdoor temperature at which the air conditioner can be used normally, and T2 is the upper limit of the outdoor temperature at which the air conditioner can be used normally.

[0097] In some embodiments of this disclosure, the recommended values ​​for L, K, and J are -7, 3, and 12 degrees Celsius, respectively.

[0098] In step 913, the relative humidity range in which the average relative humidity is located and the outdoor temperature range in which the average outdoor temperature is located are determined.

[0099] In step 914, the frost tendency level is predicted based on the relative humidity range in which the average relative humidity is located and the outdoor temperature range in which the average outdoor temperature is located.

[0100] In the embodiments of this disclosure, different combinations of relative humidity ranges and outdoor temperature ranges corresponding to the average relative humidity and average outdoor temperature correspond to different frosting tendency levels, and different levels correspond to different amounts of time adjustment, first temperature adjustment, and second temperature adjustment. Therefore, the embodiments of this disclosure can more accurately achieve optimal configuration of heat storage under various climatic conditions, ensuring sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste due to excessive heat storage, thus achieving efficient energy utilization while ensuring defrosting effectiveness. The embodiments of this disclosure can accurately determine the optimal timing for heat storage entry and exit under various weather conditions, thereby improving the energy-saving effect of heat storage air conditioning under various weather conditions.

[0101] In some embodiments of this disclosure, steps 913 and 914 may include: classifying frost tendency levels according to Table 1, when the average relative humidity and average outdoor temperature are within any range. For example, five levels are used: A, B, C, D, and E, where A is the most prone to frost and E is the least prone to frost, with the frost tendency gradually decreasing from A to E. Table 1 is a schematic table for predicting frost tendency. The filling in of the predicted frost tendency in Table 1 is only an example and is not intended to limit the scope.

[0102] Table 1

[0103] In step 92, at least one of the time threshold, the first temperature threshold, and the second temperature threshold is corrected according to the frosting tendency level.

[0104] The embodiments of this disclosure can predict the frost tendency level based on different relative humidity and the average outdoor temperature, and then correct at least one of the time threshold, the first temperature threshold, and the second temperature threshold according to the frost tendency level. Therefore, the embodiments of this disclosure can more accurately achieve the optimal configuration of heat storage under multiple climatic conditions, ensuring sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste caused by excessive heat storage, thus achieving efficient energy utilization while ensuring defrosting effectiveness. The embodiments of this disclosure can determine the optimal timing for heat storage entry and exit under various weather conditions, thereby improving the energy-saving effect of heat storage air conditioning under various weather conditions.

[0105] In some embodiments of this disclosure, step 92 may include at least one of steps 921 to 924.

[0106] In step 921, the corresponding time adjustment amount, first temperature adjustment amount, and second temperature adjustment amount are determined according to the frosting tendency level.

[0107] In some embodiments of this disclosure, different frosting tendency levels correspond to different amounts of time adjustment, first temperature adjustment, and second temperature adjustment, as shown in Table 2. Table 2 illustrates the parameter correction method based on frosting tendency.

[0108] In the embodiments of this disclosure, different frosting tendency levels correspond to different amounts of time adjustment, first temperature adjustment, and second temperature adjustment. Therefore, the embodiments of this disclosure can more accurately achieve optimal configuration of heat storage under various climatic conditions, ensuring sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste due to excessive heat storage, thus achieving efficient energy utilization while guaranteeing defrosting effectiveness. The embodiments of this disclosure can precisely determine the optimal timing for heat storage entry and exit under various weather conditions, thereby improving the energy-saving effect of heat storage air conditioning under various weather conditions.

[0109] Table 2

[0110] In some embodiments of this disclosure, the time adjustment amount can be: a1=60min, b1=30min, d1=15min, e1=30min.

[0111] In some embodiments of this disclosure, the first temperature adjustment amount is: a2=3℃, b2=2℃, d2=2℃, e2=3℃.

[0112] In some embodiments of this disclosure, the temperature parameters are adjusted as follows: a3=3℃, b3=2℃, d3=2℃, e3=3℃.

[0113] In step 922, the time threshold is corrected according to the time adjustment amount.

[0114] In step 923, the first temperature threshold is corrected according to the first temperature adjustment amount.

[0115] In step 924, the second temperature threshold is corrected according to the second temperature adjustment amount.

[0116] The embodiments of this disclosure can predict the frost tendency level based on different relative humidity and the average outdoor temperature. Then, based on the frost tendency level, at least one of the time threshold, the first temperature threshold, and the second temperature threshold can be corrected. Therefore, the embodiments of this disclosure can more accurately achieve the optimal configuration of heat storage under multiple climatic conditions. This ensures sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste caused by excessive heat storage, thus achieving efficient energy utilization while guaranteeing defrosting effectiveness. The embodiments of this disclosure can accurately determine the optimal timing for heat storage entry and exit under various weather conditions, thereby improving the energy-saving effect of heat storage air conditioning under various weather conditions.

[0117] In some embodiments of this disclosure, steps 922 to 924 may include: adjusting key control parameters (time threshold, first temperature threshold, and second temperature threshold) according to the frosting tendency prediction results (specific correction rules are shown in Table 2): when the predicted frosting tendency is level C: keep the original parameters unchanged and do not make any adjustments; when the predicted frosting tendency is level A: it is anticipated that extreme frosting conditions will occur in the future, and preparations need to be made in advance, therefore, the parameters are adjusted upwards: t C Add a1 minutes, T min Increase a2℃, T max Increasing a3℃ extends the heat storage time and raises the heat storage temperature, ensuring sufficient heat to cope with frequent defrosting needs. For other frosting tendency levels such as B, D, and E, the same parameter correction principle is applied, with specific adjustment ranges calculated according to the corresponding parameters in Table 2. The maximum heat storage time t of the heat accumulator in the above embodiments of this disclosure is... C heat storage temperature threshold T min and T max The system will adjust according to different weather conditions, while the maximum heat storage capacity of the heat storage device remains constant and will not change due to different weather conditions.

[0118] Figure 3 This is a schematic diagram of some embodiments of the air conditioning control method disclosed herein. Figure 3 This is a schematic diagram of the heat storage entry or exit condition control method in some other embodiments of this disclosure. Figure 3 The embodiments can be executed by the air conditioner or air conditioner control device of this disclosure. For example... Figure 3 As shown, Figure 3 The method of the embodiment may include at least one of steps 101 to 111.

[0119] For air conditioners equipped with energy storage functions, the heat storage mode will be activated when the system simultaneously meets the following conditions (see details below). Figure 3If any condition is not met, the system will take appropriate action based on the current operating status: if it is in heat storage mode, it will immediately exit the heat storage mode; if it is in another operating mode or in a shutdown state, the heat storage mode will not be triggered, i.e., step 111 will be executed. The order of judgment for each condition is flexible and can be adjusted according to actual needs, but all conditions must be met simultaneously to enter the heat storage mode. The absence of any condition will result in the cancellation or prevention of the heat storage mode.

[0120] In step 101, it is determined whether the air conditioner is in heating mode. If the air conditioner is in heating mode, step 102 is executed; otherwise, if the air conditioner is in cooling mode, step 111 is executed.

[0121] In some embodiments of this disclosure, the multi-split air conditioner has two overall operating modes: cooling and heating. Heat storage is only required when the unit is in heating mode; therefore, it is essential that the entire unit be in heating mode.

[0122] In the above embodiments of this disclosure, when in heating mode, the system can determine whether to enter or exit the heat storage mode based on the accumulated heat storage time and the water temperature inside the heat storage tank. Therefore, the above embodiments of this disclosure can achieve optimal configuration of the heat storage capacity through precise judgment conditions. This ensures sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste caused by excessive heat storage. Thus, energy efficiency is achieved while ensuring effective defrosting, improving the energy-saving effect of the heat storage air conditioner.

[0123] In step 102, it is determined whether the user allows the thermal storage function to be enabled. That is, the user selects whether to enable the thermal storage function of the multi-split unit via a wired controller or other means; this function is enabled by default. If the user selects to enable the thermal storage function, or if the thermal storage function is enabled by default, step 103 is executed, that is, other judgments are performed; otherwise, if the user selects not to enable the thermal storage function, step 111 is executed, that is, the unit is shut down or exits the thermal storage mode.

[0124] In the embodiments of this disclosure, when the energy storage function is activated, the system can determine whether to enter or exit the energy storage mode based on the cumulative heat storage time and the water temperature inside the heat storage unit. Therefore, the embodiments of this disclosure can achieve optimal configuration of the heat storage capacity through precise setting of heat storage entry and exit conditions. This ensures sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste caused by excessive heat storage, thereby achieving efficient energy utilization while ensuring effective defrosting and improving the energy-saving effect of the heat storage air conditioner.

[0125] In step 103, it is determined whether all indoor units of the air conditioner are turned off. If all indoor units are turned off, it means the user has no heating requirement, and step 104 is executed. Because heat storage and heating conflict in the system flow path, the heat storage in the above embodiment can only operate when heating is not required. Otherwise, if at least one indoor unit of the air conditioner is heating, step 111 is executed, that is, the air conditioner is controlled to exit the heat storage mode.

[0126] Because heat storage and heating conflict in the system flow path, the above-described embodiments of this disclosure can only operate when heating is not required. However, by precisely setting the conditions for heat storage entry and exit when all indoor units are turned off, the above-described embodiments of this disclosure can achieve optimal configuration of the heat storage capacity. This ensures sufficient heat storage for subsequent heat release and defrosting operations while avoiding energy waste caused by excessive heat storage. Thus, it achieves efficient energy utilization while ensuring effective defrosting, thereby improving the energy-saving effect of the heat storage air conditioner.

[0127] In step 104, the user-selected heat storage strategy is obtained. If the heat storage strategy is a comfort-first mode, step 106 is executed. Otherwise, if the heat storage strategy is a cost-first mode (cost reduction-first mode), step 105 is executed.

[0128] The embodiments disclosed above provide users with two heat storage strategies to choose from: Heat Storage Strategy 1: Comfort Priority Mode, which aims to improve user comfort. Considering that heat release defrosting offers a better comfort experience than conventional defrosting, and that heat release defrosting requires sufficient heat storage as a prerequisite, in Comfort Priority Mode, the system will prioritize the implementation of heat release defrosting, regardless of electricity price factors. Specifically, the system will skip the electricity price judgment step (step 105) to ensure that heat release defrosting can be initiated in a timely manner when the heat storage conditions are met, thereby providing users with a better user experience.

[0129] In step 105, it is determined whether the current electricity price is during off-peak or peak periods. If it is detected that the current electricity price is during off-peak or peak periods, step 106 is executed; if it is detected that the current electricity price is during peak periods, step 111 is executed. That is, the air conditioner is controlled to exit the heat storage mode or stop heat storage.

[0130] Regarding the entry and exit conditions for the thermal storage mode, the above embodiments of this disclosure provide users with the option to select either a comfort-first or cost-reduction-first mode to determine whether it is necessary to limit thermal storage to a low / flat electricity price range.

[0131] The second heat storage strategy in the above embodiments of this disclosure is a cost-priority mode, which primarily considers reducing operating costs. Since the heat storage process consumes electricity, performing heat storage during periods of high electricity prices will increase electricity costs. Therefore, in the cost-priority mode, the system strictly judges electricity prices (step 105). The system will only allow heat storage operation when it detects that the current period is a low-price or flat-price period; conversely, if it is a peak-price period, it will actively withdraw from or refuse heat storage, thereby effectively controlling operating costs.

[0132] In step 106, it is determined whether the cumulative heat storage time is less than or equal to the time threshold t. c If the cumulative heat storage time is greater than the time threshold, proceed to step 111; otherwise, if the cumulative heat storage time is less than or equal to the time threshold, proceed to step 107.

[0133] In some embodiments of this disclosure, the time threshold t c The time reference required for the accumulator to reach full-load heat storage state is preset for the system. This parameter can be determined through actual experimental testing and pre-programmed into the unit control system.

[0134] In some embodiments of this disclosure, the time threshold t c A typical value is 3 hours, which can be adjusted and optimized according to specific application scenarios and device characteristics.

[0135] In some embodiments of this disclosure, the time threshold t c The timing mechanism is as follows: When the unit starts the heat storage mode, the system will automatically start recording the heat storage duration. The timing rules are as follows: When the heat release defrosting mode is started, the timer is automatically reset to zero; if the unit enters other operating modes such as normal heating or normal defrosting after the heat storage is completed, the timer remains unchanged; when the unit re-enters the heat storage mode, the timer will continue to accumulate the previous heat storage duration.

[0136] In some embodiments of this disclosure, when the cumulative heat storage time reaches a time threshold t c In this case, the system will automatically end the current heat storage process and exit the heat storage mode.

[0137] In step 107, it is determined whether the air conditioner is currently in heat storage mode. If the air conditioner is currently in heat storage mode, proceed to step 109; otherwise, if the air conditioner is not currently in heat storage mode (e.g., it is in another mode or is off), proceed to step 108.

[0138] In step 108, when the system determines that it is currently in non-heat storage mode or in a shutdown state, it will enter the temperature detection stage of step 108. For energy storage systems that use water as the energy storage medium, the criteria for determining heat storage start-up are as follows: the water temperature inside the heat storage tank is detected to be lower than or equal to the second temperature threshold T. min When the water temperature inside the accumulator is detected to be lower than or equal to the second temperature threshold T. min If the heat storage in the accumulator is insufficient, step 110 is executed, and the air conditioner is controlled to start the heat storage mode; if the water temperature in the accumulator is detected to be higher than the second temperature threshold T... min If the situation is determined that there is still sufficient heat in the accumulator, step 111 is executed to control the air conditioner not to start the heat storage mode.

[0139] In some embodiments of this disclosure, the second temperature threshold T min The temperature threshold set manually can be determined through experimental testing and then fixed in the unit control program.

[0140] In some embodiments of this disclosure, the second temperature threshold T min The recommended value is 25℃, but this parameter can be adjusted appropriately according to actual operating conditions and equipment characteristics.

[0141] In step 109, when the system determines that it is currently in a heat storage state, it will enter the temperature monitoring stage (S109). This involves detecting that the water temperature inside the heat storage tank is lower than or equal to a first temperature threshold T. max When the water temperature inside the accumulator is detected to be below the first temperature threshold T... max If the accumulator's heat storage capacity is not yet at full capacity, step 110 is executed, and the control system's air conditioning continues to maintain heat storage operation; if the water temperature inside the accumulator is detected to be higher than the first temperature threshold T... max In the case of a situation where the accumulator has reached full load heat storage state, step 111 is executed to control the air conditioner to automatically exit the heat storage mode.

[0142] In some embodiments of this disclosure, the full-load heat storage state refers to the state in which the heat storage device reaches its maximum heat storage capacity.

[0143] The maximum heat storage time t of the heat accumulator in the above embodiments of this disclosure. C heat storage temperature threshold T min and T max The system will adjust according to different weather conditions, while the maximum heat storage capacity of the heat storage device remains constant and will not change due to different weather conditions.

[0144] In some embodiments of this disclosure, the first temperature threshold T max The artificially set thermal storage termination temperature threshold can be determined through experimental testing and preset in the unit control program.

[0145] In some embodiments of this disclosure, the first temperature threshold T max The recommended temperature is 35℃.

[0146] In some embodiments of this disclosure, the first temperature threshold T max With the second temperature threshold T min There is a specific relationship between them: the first temperature threshold T max Second temperature threshold T min .

[0147] The embodiments disclosed above set a first temperature threshold T. max With the second temperature threshold T min The main purpose of unequal values ​​is to avoid frequent system start-ups and shutdowns. If the two values ​​are the same, the following situation may occur: the heat storage mode has just reached the first temperature threshold T. max However, the water temperature may drop slightly below the second temperature threshold T due to factors such as natural heat loss. min At this point, the system will immediately restart heat storage, causing unnecessary cycles. By maintaining the first temperature threshold T... max Second temperature threshold T min The difference provides a reasonable temperature tolerance range for the system, effectively preventing this oscillation phenomenon.

[0148] In step 110, when the system simultaneously meets all the conditions in steps 101 to 109, the heat storage mode will be activated (see details for specific conditions). Figure 3 ).

[0149] In step 111, if any of the conditions in steps 101 to 109 are not met, the system will take corresponding actions based on the current operating state: if it is in a heat storage state, it will immediately exit the heat storage mode; if it is in another operating mode or a shutdown state, the heat storage mode will not be triggered.

[0150] The above embodiments of this disclosure provide the conditions for entering and exiting the thermal storage mode of the energy storage system, including the overall unit operation mode (whether the whole unit is in heating mode), the unit operation status (whether all indoor units are turned off), the user strategy selection (whether the user enables thermal storage), the energy storage status (the cumulative duration of thermal storage and the water temperature inside the energy storage), electricity price information, weather information, etc.

Figure 4 This is a schematic diagram of the switching condition control method between conventional defrosting and heat release defrosting modes in some embodiments of this disclosure. Figure 5 This is a schematic diagram of some embodiments of the air conditioning control method disclosed herein. Figure 5This is a schematic diagram of the control method for switching conditions between heat storage entry and exit conditions and between conventional defrosting and heat release defrosting modes in some embodiments of this disclosure. Figure 4 and Figure 5 The embodiments can be executed by the air conditioner or air conditioner control device of this disclosure. For example... Figure 4 As shown, Figure 4 The method of the embodiment may include at least one of steps 300 to 400. For example... Figure 5 As shown, Figure 5 The method in the embodiments may include, in addition to, [the following] Figure 1 In addition to at least one of the steps 100 to 200 that are the same as or similar to those in the embodiments, the embodiments may also include steps similar to those in the embodiments. Figure 4 At least one of steps 300 to 400, which are the same as or similar to those in the embodiments, are included. In some embodiments of this disclosure, Figure 4 The method steps of the embodiment may also include Figure 2 or Figure 3 In the method of the embodiment.

[0152] In step 300, when the air conditioner enters the defrosting operation state, the water temperature inside the heat storage tank is obtained.

[0153] In step 400, the air conditioner is controlled to switch to heat release defrosting mode or normal defrosting mode according to the water temperature in the heat accumulator.

[0154] In some embodiments of this disclosure, heat release defrosting refers to an air conditioner with energy storage function that completes the defrosting operation of the heat exchanger by releasing the heat stored in the energy storage device. This method can significantly improve the user's comfort experience compared to the conventional defrosting mode.

[0155] In some embodiments of this disclosure, the conventional defrosting mode refers to the technical principle of using a switching four-way valve to change the direction of refrigerant flow, so that the outdoor evaporator turns into a condenser to release heat and melt the frost layer.

[0156] The above embodiments of this disclosure specify the entry and exit conditions for the heat release defrosting mode, using the water temperature inside the accumulator during system defrosting operation as the mode switching condition.

[0157] The above embodiments of this disclosure provide the conditions for the unit to switch to heat release defrosting mode or conventional defrosting, so that the energy storage air conditioner can make full use of the stored heat for defrosting, thereby greatly improving the energy-saving effect, improving the defrosting efficiency without affecting the indoor heating effect, and avoiding the situation where heat release defrosting is still performed after the stored heat is exhausted, resulting in the inability to effectively remove the frost layer on the outdoor heat exchanger.

[0158] In some embodiments of this disclosure, step 400 may include at least one of steps 410 and 420.

[0159] In step 410, if the water temperature in the heat storage tank is higher than or equal to the mode switching temperature threshold, the air conditioner is controlled to switch to the heat release defrosting mode.

[0160] In step 420, if the water temperature in the heat storage tank is lower than the mode switching temperature threshold, the air conditioner is controlled to switch to the normal defrosting mode.

[0161] In the embodiments of this disclosure, when the water temperature is detected to be higher than or equal to the mode switching temperature threshold, it is determined that the heat storage in the accumulator is sufficient and the conditions for heat release defrosting are met, and the system immediately switches to heat release defrosting mode. When the water temperature is detected to be lower than the mode switching temperature threshold, it is determined that the heat reserve in the accumulator is insufficient and cannot meet the heat release defrosting requirements, and the system automatically switches to the conventional defrosting mode. Therefore, the embodiments of this disclosure can fully utilize the stored heat for defrosting, thereby greatly improving the energy-saving effect, improving defrosting efficiency without affecting the indoor heating effect, and avoiding the situation where heat release defrosting continues after the stored heat is exhausted, resulting in the inability to effectively remove the frost layer on the outdoor heat exchanger.

[0162] Figure 6 This is a schematic diagram of some other embodiments of the air conditioning control method disclosed herein. Figure 6 This diagram illustrates the switching condition control method between conventional defrosting and heat release defrosting modes in some embodiments of this disclosure. The air conditioning control method of this disclosure includes... Figures 1 to 5 In addition to at least one step in the method of any embodiment, it may also include Figure 6 At least one of steps 201 to 205 in the embodiment. The air conditioning control method of this disclosure may also include only... Figure 6 At least one of steps 201 to 205 in the embodiment.

[0163] The mode switching conditions in the above embodiments of this disclosure are as follows: For air conditioners equipped with energy storage function, when the system simultaneously meets all the conditions in steps 201 to 203, it will switch to the heat release defrosting operation mode (see details for specific conditions). Figure 6 Step 204 of the embodiment); if any condition in steps 201 to 203 is not met, the system will use the conventional defrosting mode to perform the defrosting operation ( Figure 6 Step 205 of the embodiment).

[0164] In the embodiments disclosed above, the phrase "switch to heat release defrosting mode" does not mean that the unit immediately performs heat release defrosting, but rather that when the system detects that defrosting is required, it will process the operation according to the heat release defrosting mode. Similarly, "switch to conventional defrosting mode" means that when the defrosting conditions are met, the system will use the conventional defrosting mode to perform the defrosting operation.

[0165] In step 201, it is determined whether the air conditioner is in heating mode. If the air conditioner is in heating mode, step 202 is executed; otherwise, if the air conditioner is in cooling mode, step 206 is executed to control the air conditioner not to perform defrosting.

[0166] The multi-split air conditioner of the above embodiments of this disclosure has two overall unit modes: cooling and heating. Defrosting is only required when the unit is in heating mode; therefore, the entire unit must be in heating mode.

[0167] The switching conditions between the conventional defrosting and heat release defrosting modes in the above embodiments of this disclosure may also include whether the whole unit is in heating mode. Therefore, the above embodiments of this disclosure can make full use of the heat stored in the heating mode for defrosting, thereby greatly improving the energy-saving effect, improving the defrosting efficiency without affecting the indoor heating effect, and avoiding the situation where heat release defrosting is still performed after the heat stored is exhausted, resulting in the inability to effectively remove the frost layer on the outdoor heat exchanger.

[0168] In step 202, it is determined whether the air conditioner's heat release function is enabled, i.e., whether the user allows the heat release function to be enabled. The user can select whether to enable the heat release function of the energy storage multi-split unit through a wired controller or other means; the default is enabled. If the air conditioner's heat release function is enabled (either when the user selects to enable it or it is enabled by default), step 203 is executed to perform other determinations; otherwise, if the air conditioner's heat release function is not enabled (if the user selects not to enable it), step 205 is executed to control the air conditioner to switch to the normal defrosting mode.

[0169] The switching conditions between the conventional defrosting and heat release defrosting modes in the above embodiments of this disclosure may also include whether the heat release function is enabled. Therefore, the above embodiments of this disclosure can make full use of the stored heat for defrosting, thereby greatly improving the energy-saving effect, improving the defrosting efficiency without affecting the indoor heating effect, and avoiding the situation where heat release defrosting is still performed after the stored heat is exhausted, resulting in the inability to effectively remove the frost layer on the outdoor heat exchanger.

[0170] In step 203, when the system enters the defrosting operation state, the water temperature inside the accumulator will be detected once. That is, when the defrosting mode starts, it is determined that the water temperature inside the accumulator is higher than or equal to the mode switching temperature threshold T0. If the water temperature inside the accumulator is higher than or equal to the mode switching temperature threshold, it is determined that the heat storage in the accumulator is sufficient and the conditions for heat release defrosting are met, and the system immediately switches to the heat release defrosting mode and executes step 204; otherwise, if the water temperature inside the accumulator is lower than the mode switching temperature threshold, it is determined that the heat reserve in the accumulator is insufficient and cannot meet the heat release defrosting requirements, and the system automatically switches to the normal defrosting mode and executes step 205.

[0171] In some embodiments of this disclosure, the switching temperature threshold T0 is a system-preset defrosting mode switching temperature threshold, which can be determined through experimental testing and fixed in the unit control program.

[0172] In some embodiments of this disclosure, the recommended value for the switching temperature threshold T0 can be 20°C.

[0173] In step 204, for air conditioners equipped with energy storage function, when the system simultaneously meets all the conditions in steps 201 to 203, it will switch to the heat release defrosting operation mode.

[0174] In step 205, if any of the conditions in steps 201 to 203 are not met, the system will use the conventional defrosting mode to perform the defrosting operation.

[0175] In step 206, when the air conditioner is in cooling mode, defrosting is not required, and the air conditioner is controlled not to perform defrosting operation.

[0176] The temperature detection in the above embodiments of this disclosure is only performed once when the defrosting process is started. Once the system enters the defrosting operation state, the water temperature will not be detected again, ensuring the continuity and stability of the defrosting process.

[0177] The above embodiments of this disclosure provide the switching conditions between conventional defrosting and heat release defrosting modes, including the overall unit operating mode (whether the whole unit is in heating mode), the unit operating status (whether defrosting mode is enabled), the user strategy selection (whether the user enables heat storage), and the accumulator status (water temperature inside the accumulator).

[0178] The embodiments disclosed above can automatically, intelligently, and accurately enter or exit the heat storage and defrosting mode according to actual usage.

[0179] The embodiments disclosed above can enter or exit the heat storage and defrosting mode according to actual operating conditions (system operation mode, unit operation status, energy storage status, user strategy selection, environmental information, electricity price information, etc.), so that the system has sufficient and necessary conditions for heat storage and defrosting under any circumstances, thereby improving defrosting efficiency while maintaining stable indoor temperature without affecting the heating effect of the indoor unit.
