The thermal storage device stores a thermal storage medium, and the method for determining the duration of thermal storage includes: When the current temperature of the thermal storage medium is less than or equal to the fourth temperature threshold, it is determined that the thermal storage continuity condition is met.

[0007] In some embodiments of this application, the heat storage device stores a heat storage medium, and the heat storage based on the heat storage device includes: Switch the current operating mode to the thermal storage mode so that the thermal storage medium can be heated; The difference between the temperature of the heat storage medium and the fifth temperature threshold is calculated to obtain the second temperature difference; The heating rate of the heat storage medium is adjusted according to the second temperature difference until the medium temperature is greater than or equal to the fifth temperature threshold, at which point the heat storage mode is exited.

[0008] In some embodiments of this application, the fifth temperature threshold is determined in the following manner: Obtain the first mapping relationship of the current outdoor thermometer; wherein, the first mapping relationship is used to indicate the negative correlation between the outdoor temperature and the temperature threshold; Based on the first mapping relationship, the temperature threshold corresponding to the current outdoor temperature is determined as the fifth temperature threshold.

[0009] In some embodiments of this application, the heat storage device is connected to the indoor heat exchanger through the internal pipe of the air conditioner, the heat storage device stores a heat storage medium, and the heat storage device is connected to an atomizing device. The method of regulating indoor temperature based on the heat in the heat storage device includes: The pipe temperature of the internal pipeline is compared with the sixth temperature threshold to obtain the comparison result; Based on the comparison results, a target adjustment action is determined from the first adjustment action and the second adjustment action; wherein, the first adjustment action is the action of heat exchange between the heat storage device and the inner pipeline, and the second adjustment action is the action of the atomizing device atomizing the heat storage medium. The target adjustment action uses the heat in the heat storage device to regulate the indoor temperature.

[0010] In some embodiments of this application, determining the target adjustment action from the first adjustment action and the second adjustment action based on the comparison result includes: When the comparison result indicates that the pipe temperature of the inner pipe is greater than or equal to the sixth temperature threshold, the first adjustment action and the second adjustment action are determined as the target adjustment action. When the comparison result shows that the pipe temperature of the inner pipe is less than the sixth temperature threshold, the second adjustment action is determined as the target adjustment action.

This solution effectively offsets the temperature drop caused by heat extraction from the indoor unit during defrosting, ensuring that the indoor temperature remains in a stable equilibrium state throughout the defrosting process. This precisely solves the problem of drastic room temperature fluctuations and significantly reduced user thermal comfort caused by heat absorption during defrosting in traditional air conditioners.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This invention provides a method, apparatus, medium, and air conditioner for defrosting with heat storage in an air conditioner. In some embodiments of this application, the provided method for defrosting with heat storage in an air conditioner can be applied to an air conditioner. Specifically, the air conditioner can be applied to different scenarios, including but not limited to industrial air conditioners or household air conditioners. In some embodiments of this application, the air conditioner can be a single unit, such as a cabinet air conditioner or a wall-mounted air conditioner; in some embodiments of this application, the air conditioner can also be a central air conditioning system composed of multiple air conditioner units, such as a multi-split air conditioner, an air-cooled heat pump system, or an air conditioning system with heat recovery function.

[0022] Please see Figure 1 , Figure 1 This is a flowchart illustrating an air conditioning heat storage defrosting method provided in an embodiment of this application. Although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown in the figures.

[0023] The air conditioner in this application includes a heat storage device, optionally, such as Figure 2 As shown, Figure 2 This is a partial connection diagram of an air conditioner, which includes a heat storage device 100, an electronic expansion valve 200, an indoor heat exchanger 300, an atomizing device 400, and a water circuit shut-off valve 500. The heat storage device 100 is connected to the electronic expansion valve 200 through the air conditioner's internal piping. The electronic expansion valve 200, in turn, forms a heat exchange path with the indoor heat exchanger 300. The heat storage device 100 is also connected to the atomizing device 400, and both devices have a water circuit shut-off valve 500 in their water circuits.

[0024] Among them, the heat storage device 100, as the core energy storage component for air conditioning defrosting, stores a heat storage medium (which can be water or other media) and serves as the carrier for heat storage and release. The electronic expansion valve 200, as the flow and heat exchange control component for the heat storage and defrosting process, is used to regulate the flow between the heat storage device and the air conditioning internal piping. Figure 2 The medium flow between the pipes (thick lines in the middle) regulates the heating rate of the heat storage medium and controls the start, stop, and intensity of heat exchange between the heat storage device and the internal pipes. The indoor heat exchanger 300 is the heat exchange component between the air conditioner and the indoor environment. It receives the heat released by the heat storage device through the internal pipes and transfers the heat to the indoor space, thus regulating the indoor temperature during defrost mode. The atomizing device 400, as an auxiliary heat release component during the defrost stage, atomizes the heat storage medium in the heat storage device and outputs an atomization cutoff in the direction of the arrow. Heat is released through contact between the atomized medium and the indoor air, completing the auxiliary action of indoor temperature regulation. The water circuit shut-off valve 500, as the water circuit on / off control component of the atomizing device, controls the opening and closing of the water circuit supplying the heat storage medium from the heat storage device to the atomizing device, thereby controlling the on / off operation of the atomization heat release.

[0025] Specifically, the detailed process of this air conditioner heat storage defrosting method is as follows: S101, when the target thermal storage conditions are met, thermal storage is carried out based on the thermal storage device.

[0026] Among them, the target thermal storage conditions refer to the set of conditions under which the air conditioner determines that thermal storage is feasible.

[0027] In some embodiments of this application, the target thermal storage conditions include at least one of thermal storage urgency conditions, thermal storage safety conditions, and thermal storage continuity conditions. Before thermal storage is performed based on the thermal storage device, the following steps are also included: when the thermal storage urgency conditions are met, and / or when the thermal storage safety conditions are met, and / or when the thermal storage continuity conditions are met, it is determined that the target thermal storage conditions are met.

[0028] Among them, the urgent conditions for thermal storage refer to the criteria under which it is determined that thermal storage needs to be started immediately. The safety conditions for thermal storage refer to the criteria under which thermal storage can be carried out to avoid safety problems during the process. The continuous conditions for thermal storage refer to the criteria under which it is determined that the thermal storage medium still needs to be continuously heated.

[0029] In this embodiment, if any one, any two, or all three of the following conditions are met, it is determined that the target thermal storage conditions are met: urgent thermal storage conditions, safe thermal storage conditions, and thermal storage demand conditions.

[0030] In some embodiments of this application, the method for determining the urgent thermal storage condition specifically includes the following steps: when the current outdoor temperature is less than or equal to a first temperature threshold and the first temperature difference is greater than or equal to a second temperature threshold, it is determined that the urgent thermal storage condition is met.

[0031] The first temperature difference is the difference between the target indoor temperature and the current indoor temperature.

[0032] Optionally, the first temperature threshold is preferably set to 6℃, but it can also be any other value; the second temperature threshold is preferably set to 0.5℃, but it can also be any other value. Under the premise that the compressor is running, when the air conditioner detects that the current outdoor temperature is 5℃ (less than or equal to 6℃), and the user-set target indoor temperature is 26℃, and the current indoor temperature is 25.3℃, and the first temperature difference between the two is 0.7℃ (greater than or equal to 0.5℃), it can be determined that the urgent heat storage conditions of the air conditioner are met, and the heat storage device needs to be activated to carry out heat storage operations.

[0033] Understandably, if the outdoor temperature is less than or equal to the first temperature threshold, it means that the outdoor ambient temperature is low, the outdoor unit of the air conditioner is prone to frost formation, and the need for subsequent defrosting is urgent. If the first temperature difference is greater than or equal to the second temperature threshold, it means that the current indoor temperature has not met the user's target temperature, and the user has already experienced discomfort. If heat is not stored in time at this point, the air conditioner will draw heat from the indoor unit during subsequent defrosting, which will further widen the gap between the actual indoor temperature and the target temperature, exacerbating the user's discomfort. Therefore, it is necessary to trigger heat storage in time by judging this condition to avoid further fluctuations in indoor temperature.

[0034] In some embodiments of this application, the internal pipes of the air conditioner are connected to the heat storage device. The method for determining the heat storage safety conditions specifically includes the following steps: when the pipe temperature of the internal pipe is greater than or equal to a third temperature threshold, it is determined that the heat storage safety conditions are met.

[0035] Optionally, the third temperature threshold can be set to -2℃, but other values ​​are also possible. When the air conditioner detects that the actual pipe temperature of the internal pipe connected to the heat storage device is -1℃ (greater than or equal to -2℃), it can be determined that the heat storage safety conditions of the air conditioner are met; if the actual pipe temperature of the internal pipe is detected to be -3℃ (less than -2℃), it is determined that the heat storage safety conditions are not met.

[0036] Understandably, when the internal pipe temperature is greater than or equal to the third temperature threshold, it indicates that the evaporator temperature is not too low. At this time, opening the water circuit for heat storage and heat exchange or atomized spraying will prevent the heat storage medium in the heat storage device from freezing instantly due to contact with the low-temperature pipes and evaporator. This avoids the situation where the medium expands and cracks the hot water storage tank, air conditioning internal pipes, and other equipment after freezing, ensuring that heat storage operations are carried out in a safe equipment operating environment. If the internal pipe temperature is lower than the third temperature threshold, the evaporator is in an extremely cold state. Performing water circuit-related operations at this time will cause the risk of freezing. Therefore, this condition should be used as the basis for judging the safety of heat storage to ensure the safe operation of the equipment.

[0037] In some embodiments of this application, the heat storage device stores a heat storage medium, and the method for determining the heat storage continuity condition specifically includes the following steps: when the current medium temperature of the heat storage medium is less than or equal to a fourth temperature threshold, it is determined that the heat storage continuity condition is met.

[0038] Optionally, the fourth temperature threshold can be set as the target temperature of the heat storage medium (e.g., 50°C) minus the first fixed value (e.g., 1°C). If the air conditioner detects that the current medium temperature of the heat storage medium in the heat storage device is 48°C (less than or equal to 49°C), it can be determined that the heat storage continuous condition is met.

[0039] It is understandable that when the current temperature of the heat storage medium is less than or equal to the threshold, it means that the medium temperature has not yet reached the target water temperature, and the stored heat is insufficient to meet the indoor temperature regulation requirements during subsequent defrosting. Therefore, it is necessary to continue heating in the heat storage mode. When the medium temperature exceeds the threshold and reaches the target water temperature, it means that the heat storage medium has stored enough heat and there is no need to continue heating.

[0040] In some embodiments of this application, the heat storage device stores a heat storage medium. S101, which involves heat storage based on the heat storage device, specifically includes the following steps: switching the current operating mode to a heat storage mode to heat the heat storage medium; calculating the difference between the temperature of the heat storage medium and a fifth temperature threshold to obtain a second temperature difference; adjusting the heating rate of the heat storage medium according to the second temperature difference until the medium temperature is greater than or equal to the fifth temperature threshold, and then exiting the heat storage mode.

[0041] Optionally, in thermal storage mode, the electronic expansion valve is opened, and its initial opening is adjusted to a preset value g1, establishing basic flow conditions for subsequent heat exchange and heating rate adjustment. During the heating process, the air conditioner continuously monitors the real-time temperature of the thermal storage medium within the thermal storage device, while simultaneously retrieving a preset fifth temperature threshold (this threshold can be set as the basic target temperature of the thermal storage medium plus a second fixed value; for example, if the basic target water temperature is 50℃, the fifth temperature threshold is 50.5℃). Furthermore, the difference between the current temperature of the thermal storage medium and the fifth temperature threshold is calculated in real time; this difference is the second temperature difference. Combined with the PID closed-loop control logic of the electronic expansion valve, the heating rate is dynamically adjusted at preset fixed intervals, specifically by adjusting the opening of the electronic expansion valve using the following formula:

[0042] In the above formula, This represents the change in the opening degree of the electronic expansion valve; This is the second temperature difference at the current moment; The second temperature difference at any given time; This is the second temperature difference from the previous moment; Sampling duration; This is the proportionality coefficient; The integral coefficient; is the differential coefficient.

[0043] The opening degree of the electronic expansion valve directly affects the flow rate of the medium in the heat storage system. A larger opening degree increases the heating rate, while a smaller opening degree decreases the heating rate. Throughout the heating process, the air conditioner continuously compares the real-time temperature of the heat storage medium with the fifth temperature threshold. When the current temperature of the heat storage medium is detected to be greater than or equal to the fifth temperature threshold, it indicates that the heat storage medium has reached the preset heat storage temperature standard, and the stored heat is sufficient to meet the indoor temperature adjustment requirements during subsequent defrosting. At this time, the air conditioner will stop heating the heat storage medium and exit the heat storage mode. Simultaneously, the electronic expansion valve returns to its normal opening degree, and the heat storage process is officially completed.

[0044] In some embodiments of this application, the fifth temperature threshold is determined as follows: A first mapping relationship of the current outdoor thermometer is obtained. Based on the first mapping relationship, the temperature threshold corresponding to the current outdoor temperature is determined as the fifth temperature threshold.

[0045] The first mapping relationship is used to indicate the negative correlation between outdoor temperature and temperature threshold.

[0046] Optionally, the mapping relationship between outdoor temperature ranges and corresponding temperature thresholds is set as follows: when 10℃ ≥ outdoor temperature > 5℃, the temperature threshold = 45℃; when 5℃ ≥ outdoor temperature > 0℃, the temperature threshold = 50℃; when 0℃ ≥ outdoor temperature, the temperature threshold = 55℃. When the air conditioner detects that the current actual outdoor temperature is 7℃, it falls within the range of 10℃ ≥ T2 > 5℃, so the fifth temperature threshold is determined to be 45℃; if the detected outdoor temperature is 3℃, it falls within the range of 5℃ ≥ T2 > 0℃, so the fifth temperature threshold is determined to be 50℃; if the detected outdoor temperature is -2℃, it satisfies 0℃ ≥ T2, so the fifth temperature threshold is determined to be 55℃.

[0047] It is understandable that the lower the outdoor temperature, the more likely the air humidity and temperature conditions will cause the outdoor unit to frost, and the thicker the frost layer will be. The more heat is needed to melt the thick frost layer. Therefore, through the negative correlation mapping relationship, a higher fifth temperature threshold is matched to the lower outdoor temperature, so that the heat storage medium is heated to a higher temperature, thereby storing more heat. In the subsequent defrosting mode, the heat storage device can release enough heat to compensate for the indoor temperature and avoid indoor temperature fluctuations due to insufficient heat required for defrosting.

[0048] S102, after entering defrosting mode, adjusts the indoor temperature based on the heat in the heat storage device to keep the indoor temperature in a balanced state.

[0049] In some embodiments of this application, the heat storage device is connected to an indoor heat exchanger via the internal piping of an air conditioner. The heat storage device stores a heat storage medium and is connected to an atomizing device. S102, which adjusts the indoor temperature based on the heat in the heat storage device, specifically includes the following steps: comparing the pipe temperature of the internal piping with a sixth temperature threshold to obtain a comparison result; determining a target adjustment action from the first adjustment action and the second adjustment action based on the comparison result; and adjusting the indoor temperature using the heat in the heat storage device through the target adjustment action.

[0050] The target adjustment action refers to the action selected from the first and second adjustment actions that is actually used to adjust the indoor temperature. The first adjustment action is the action of heat exchange between the heat storage device and the internal piping, and the second adjustment action is the action of the atomizing device atomizing the heat storage medium.

[0051] Optionally, the air conditioner determines and executes a target adjustment action from the first and second adjustment actions based on the comparison results. In specific execution, such as... Figure 2As shown, the first adjustment action is controlled by an electronic expansion valve to start / stop and adjust the operating intensity, while the second adjustment action is controlled by a water circuit shut-off valve. Based on preset judgment rules or manual screening, a target adjustment action is determined from the first and second adjustment actions. Finally, the target adjustment action is used to regulate the indoor temperature using the heat from the thermal storage device.

[0052] The above embodiments can flexibly select the heat exchange method of the heat storage device or the atomization heat release method to release the pre-stored heat according to the pipeline temperature conditions, so as to achieve targeted compensation and adjustment of indoor temperature. The flexible selection of the two types of adjustment actions also makes the indoor temperature adjustment more adaptable and effective.

[0053] In some embodiments of this application, a target adjustment action is determined from the first adjustment action and the second adjustment action based on the comparison result. Specifically, this includes the following steps: when the comparison result indicates that the pipe temperature of the inner pipe is greater than or equal to a sixth temperature threshold, the first adjustment action and the second adjustment action are determined as the target adjustment action. When the comparison result indicates that the pipe temperature of the inner pipe is less than the sixth temperature threshold, the second adjustment action is determined as the target adjustment action.

[0054] Optionally, if the pipeline temperature is greater than or equal to the sixth temperature threshold, the first adjustment action of the heat storage device and the internal pipeline heat exchange, and the second adjustment action of the atomizing device atomizing the heat storage medium are both set as the target adjustment action. At this time, the electronic expansion valve is fully opened and the water circuit shut-off valve is opened to perform dual actions. If the pipeline temperature is less than the sixth temperature threshold, only the second adjustment action is set as the target adjustment action. At this time, the electronic expansion valve is closed and the water circuit shut-off valve is opened, and only the fallback action of atomization heat release is performed.

[0055] Understandably, when the internal pipe temperature is greater than or equal to the sixth temperature threshold, the pipe temperature is within a safe range. At this time, performing the first adjustment action will not cause the heat storage medium to freeze upon contact with the low-temperature pipe. Combined with the second adjustment action, efficient heat release can be achieved, maximizing the compensation for indoor temperature. When the internal pipe temperature is less than the sixth temperature threshold, the pipe temperature is too low. Performing the first adjustment action may easily cause the medium to freeze and the equipment to crack. Therefore, the electronic expansion valve is closed to stop the first adjustment action. The second adjustment action, which is performed only by opening the water circuit shut-off valve, completes the fallback temperature compensation. This ensures the basic needs of indoor temperature regulation and fundamentally avoids potential safety hazards in equipment operation.

[0056] Optionally, the indoor temperature is determined to be in a balanced state when the following conditions are met: the difference between the actual indoor temperature and the target temperature is within a preset range (e.g., ±0.5℃); or the rate of change of the indoor temperature over a fixed period of time is lower than a specific threshold.

[0057] Furthermore, when the air conditioner detects that the defrosting exit conditions are met and exits the defrosting function, it immediately closes the electronic expansion valve used to control the first adjustment action, and at the same time closes the water circuit shut-off valve that controls the second adjustment action, so as to cut off the heat exchange passage between the heat storage device and the internal pipeline, and the medium delivery water passage from the heat storage device to the atomizing device. The heat storage device stops releasing heat, and the air conditioner officially ends the indoor temperature regulation control in the defrosting mode and returns to the normal operating state.

[0058] The above embodiments, by pre-storing heat using a heat storage device when the target heat storage conditions are met, and after entering the defrost mode, although the system still needs to draw heat from the room to melt the frost layer on the outdoor unit, it effectively offsets the temperature drop caused by drawing heat from the room during the defrost process by releasing the pre-stored heat in the heat storage device to compensate and regulate the room in real time. This ensures that the indoor temperature remains in a stable equilibrium state during the defrost period, thereby precisely solving the problem of drastic room temperature fluctuations and significant reduction in user thermal comfort caused by heat absorption during defrost in traditional air conditioners.

[0059] To facilitate better implementation of the air conditioning heat storage defrosting method of this application, this application also provides an air conditioning heat storage defrosting device based on the above-described air conditioning heat storage defrosting method. The meanings of the terms used are the same as in the above-described air conditioning heat storage defrosting method, and specific implementation details can be found in the descriptions of the method embodiments.

[0060] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of the air conditioning heat storage defrosting device provided in the embodiments of this application, which may specifically include: The thermal storage module 301 is used to store heat based on the thermal storage device when the target thermal storage conditions are met. The defrosting module 302 is used to adjust the indoor temperature based on the heat in the heat storage device after entering the defrosting mode, so as to keep the indoor temperature in a balanced state.

[0061] In the above embodiment, the heat storage module 301 stores heat in advance using a heat storage device when the target heat storage conditions are met. The defrosting module 302, after entering defrosting mode, although the system still needs to draw heat from the indoor environment to melt the frost layer on the outdoor unit, releases the pre-stored heat in the heat storage device to compensate and regulate the indoor environment in real time. This solution effectively offsets the temperature drop caused by heat extraction from the indoor environment during the defrosting process, ensuring that the indoor temperature remains in a stable equilibrium state during defrosting. This precisely solves the problem of drastic room temperature fluctuations and significant reduction in user thermal comfort caused by heat absorption during defrosting in traditional air conditioners.

[0062] In some embodiments of this application, the target thermal storage conditions include at least one of thermal storage urgency conditions, thermal storage safety conditions, and thermal storage continuous conditions. Before the thermal storage module 301 performs thermal storage based on the thermal storage device, it further includes: The target thermal storage conditions are determined to be met when the urgent thermal storage conditions are met, and / or the safe thermal storage conditions are met, and / or the sustainable thermal storage conditions are met.

[0063] In some embodiments of this application, the method for determining the urgent heat storage conditions of the heat storage module 301 includes: When the current outdoor temperature is less than or equal to the first temperature threshold and the first temperature difference is greater than or equal to the second temperature threshold, the urgent condition for thermal storage is determined to be met; where the first temperature difference is the difference between the target indoor temperature and the current indoor temperature. The connection between the air conditioner's internal piping and the heat storage device, and the methods for determining the safety conditions of the heat storage, include: When the temperature of the internal pipeline is greater than or equal to the third temperature threshold, the thermal storage safety conditions are deemed met. The thermal storage device stores a thermal storage medium. The methods for determining the sustainability of thermal storage conditions include: When the current temperature of the thermal storage medium is less than or equal to the fourth temperature threshold, the thermal storage continuity condition is determined to be met.

[0064] In some embodiments of this application, the heat storage device stores a heat storage medium, and the heat storage module 301 performs heat storage based on the heat storage device, including: Switch the current operating mode to the thermal storage mode to heat the thermal storage medium; The difference between the temperature of the heat storage medium and the fifth temperature threshold is calculated to obtain the second temperature difference; The heating rate of the thermal storage medium is adjusted according to the second temperature difference until the medium temperature is greater than or equal to the fifth temperature threshold, at which point the thermal storage mode is exited.

[0065] In some embodiments of this application, the fifth temperature threshold of the thermal storage module 301 is determined in the following manner: Obtain the first mapping relationship of the current outdoor thermometer; wherein, the first mapping relationship is used to indicate the negative correlation between the outdoor temperature and the temperature threshold; Based on the first mapping relationship, the temperature threshold corresponding to the current outdoor temperature is determined as the fifth temperature threshold.

[0066] In some embodiments of this application, the heat storage device is connected to the indoor heat exchanger through the internal pipes of an air conditioner, the heat storage device stores a heat storage medium, and the heat storage device is connected to an atomizing device. The defrosting module 302 regulates the indoor temperature based on the heat in the heat storage device, including: The pipe temperature of the internal pipeline is compared with the sixth temperature threshold to obtain the comparison result; Based on the comparison results, the target adjustment action is determined from the first adjustment action and the second adjustment action; wherein, the first adjustment action is the action of heat exchange between the heat storage device and the inner pipeline, and the second adjustment action is the action of the atomizing device atomizing the heat storage medium. The indoor temperature is regulated by using the heat stored in the thermal storage device through a target adjustment action.

Optionally, the processor 401 may include one or more processing cores; preferably, the processor 401 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, and the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 401.

[0069] The memory 402 can be used to store software programs and modules. The processor 401 executes various functional applications and data processing by running the software programs and modules stored in the memory 402. The memory 402 may mainly include a program storage area and a data storage area. The program storage area may store the operating system, at least one application program required for a function, etc.; the data storage area may store data created based on the use of the air conditioner, etc. In addition, the memory 402 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device. Accordingly, the memory 402 may also include a memory controller to provide the processor 401 with access to the memory 402.

[0070] The air conditioner also includes a power supply 403 that supplies power to the various components.

[0072] Although not shown, the air conditioner may also include a display unit, etc., which will not be described in detail here.

[0073] In the above embodiment, heat is pre-stored using a heat storage device when the target heat storage conditions are met. While the system still needs to draw heat from the indoor unit to melt the frost layer on the outdoor unit after entering defrost mode, it releases the pre-stored heat in the heat storage device to compensate and regulate the indoor temperature in real time. This solution effectively offsets the temperature drop caused by heat extraction from the indoor unit during defrost, ensuring that the indoor temperature remains stable and balanced throughout the defrost process. This precisely solves the problem of drastic room temperature fluctuations and significantly reduced user thermal comfort caused by heat absorption during defrost in traditional air conditioners.
