[0005] The related technology realizes the recycling of regenerative potential energy. However, in addition to regenerative potential energy, there is also waste of other energy, such as wind energy. When the outdoor unit of the air conditioner is running, the outdoor fan sends wind energy directly to the external environment, thereby causing energy waste. SUMMARY

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, the following brief summary is given. The summary is not an overall description of the application, nor is it intended to identify key / important elements or delineate the scope of the embodiments. It is only a prelude to the detailed description below.

[0007] The embodiments of the present disclosure provide a method and device for controlling an air conditioner, an air conditioner and a storage medium to make full use of the wind energy generated by the operation of the outdoor fan.

[0008] In some embodiments, the air conditioner comprises two energy conversion structures and two heat storage structures, wherein the energy conversion structure corresponds to the heat storage structure one by one; the energy conversion structure can convert the wind energy generated by the operation of the outdoor fan into heat energy when the energy conversion structure is running, and the heat energy is conducted to the corresponding heat storage structure; the heat storage structure is in contact with the outdoor heat exchanger to exchange heat with the outdoor heat exchanger; a heat transfer pipeline is arranged between the two heat storage structures to balance the conduction temperature of the two heat storage structures; the method comprises: obtaining the operation mode of the air conditioner; in the case that the operation mode is a heating mode, obtaining the operation state of the air conditioner; and controlling the operation of the energy conversion structure and the heat transfer pipeline according to the operation state of the air conditioner.

[0009] In some embodiments, the device comprises a processor and a memory storing program instructions, wherein the processor is configured to execute the foregoing method for controlling an air conditioner when the program instructions are running.

[0010] In some embodiments, the air conditioner comprises two energy conversion structures and two heat storage structures, one energy conversion structure corresponding to one heat storage structure; wherein the energy conversion structure is capable of converting wind energy generated by the operation of the outdoor fan into heat energy when the energy conversion structure is running, and conducting the heat energy to the corresponding heat storage structure; the heat storage structure is in contact with the outdoor heat exchanger to exchange heat with the outdoor heat exchanger; the heat transfer pipeline is arranged between the two heat storage structures to balance the conduction temperature of the two heat storage structures; and the device for controlling the air conditioner as described above.

[0011] In some embodiments, the storage medium stores program instructions, which when executed, perform the method for controlling the air conditioner as described above.

[0012] The method, device, air conditioner and storage medium for controlling the air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0013] First, the running mode of the air conditioner is determined to determine whether there is a need for defrosting. When the air conditioner is running in the heating mode, the running state of the air conditioner is further determined to determine whether the air conditioner enters defrosting. Then, based on the running state of the air conditioner, the running of the energy conversion structure and the heat transfer pipeline is controlled. So that the running state of the energy conversion structure and the on-off state of the heat transfer pipeline meet the state required by the air conditioner running in the normal heating mode or running in the defrosting phase. When the energy conversion structure is running, it can convert the wind energy generated by the operation of the outdoor fan into heat energy, and conduct the heat energy to the corresponding heat storage structure. The heat storage structure then conducts heat to the outdoor heat exchanger to increase the temperature of the refrigerant. If the air conditioner does not enter defrosting, conducting heat to the outdoor heat exchanger can increase the evaporation temperature of the outdoor heat exchanger, thereby improving the heating effect. If the air conditioner enters defrosting, conducting heat to the outdoor heat exchanger can assist defrosting, thereby improving the defrosting effect. Moreover, the heat conducted by the heat storage structure to the outdoor heat exchanger is derived from the conversion of wind energy generated by the operation of the outdoor fan. The wind energy generated by the operation of the outdoor fan is fully utilized, and energy saving is achieved.

DETAILED DESCRIPTION

[0030] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure is described in detail below, and the accompanying drawings are used for reference only and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, through multiple details, a sufficient understanding of the disclosed embodiments is provided. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to facilitate the drawings.

[0031] The terms "first", "second", and the like in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0032] Unless otherwise specified, the term "multiple" means two or more.

[0033] In the embodiments of the present disclosure, the character " / " represents that the objects before and after are in an "or" relationship. For example, A / B represents: A or B.

[0034] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, three relationships.

[0035] The term "corresponding" can refer to an association or binding relationship, A corresponding to B means that there is an association or binding relationship between A and B.

[0036] In combination Figure 1 As shown, the embodiments of the present disclosure provide an air conditioner. The air conditioner includes: an indoor unit and an outdoor unit. The outdoor unit includes: an outdoor casing 10, an outdoor heat exchanger 20 arranged in the outdoor casing 10, an outdoor fan 30, and a compressor 50. The outdoor fan 30 is fixed in the interior of the outdoor casing 10 through a fan support 40. The compressor 50 is arranged in a compressor cabin 80.

[0037] Optionally, in combination Figure 2 and Figure 3As shown, the fan support 40 comprises a mounting plate 41 and two connecting plates 42. The two connecting plates 42 are connected to the two ends of the mounting plate 41 and are at an angle, for example, 90°, with the mounting plate 41. Meanwhile, the two connecting plates 42 are connected to the two opposite inner side walls of the outer casing 10 respectively. In this way, the fan support 40 is more firmly fixed inside the outer casing 10 by connecting the mounting plate 41 and the connecting plates 42 to the inner walls of the outer casing 10. The middle part of the mounting plate 41 is provided with a mounting hole 411. The base 31 of the outdoor fan 30 is installed in the mounting hole 411. Meanwhile, the mounting plate 41 is arranged close to the outdoor heat exchanger 20.

[0038] The air conditioner further comprises an auxiliary defrosting device arranged on the fan support 40, which can convert the wind energy generated when the outdoor fan 30 operates into heat energy and provide the heat energy to the outdoor heat exchanger 20 to increase the temperature of the outdoor heat exchanger 20. Here, the auxiliary defrosting refers to controlling the auxiliary defrosting device to operate for auxiliary defrosting on the basis of sensible heat defrosting (controlling the reversing of the four-way valve) or latent heat defrosting.

[0039] Referring again to Figure 3 , the auxiliary defrosting device comprises one or two conversion heat transfer mechanisms 60. When one conversion heat transfer mechanism 60 is included, it is arranged on one side of the mounting hole 411, for example, above or below the mounting hole 411. When two conversion heat transfer mechanisms 60 are included, the two conversion heat transfer mechanisms 60 are arranged on the two sides of the mounting hole 411 respectively, for example, one is arranged above the mounting hole 411 and the other is arranged below the mounting hole 411. In this way, the heat transfer area of the conversion heat transfer mechanism 60 and the outdoor heat exchanger 20 can be increased, thereby increasing the heat transfer rate.

[0040] Referring again to Figure 3 , the conversion heat transfer mechanism 60 comprises two energy conversion structures 61 and two heat storage structures 62 arranged on the fan support 40. One energy conversion structure 61 corresponds to one heat storage structure 62. The energy conversion structure 61 can convert the wind energy generated when the outdoor fan 30 operates into heat energy. Meanwhile, the heat energy is conducted to the heat storage structure 62. The heat storage structure 62 is in contact with the outdoor heat exchanger 20 to exchange heat with the outdoor heat exchanger 20, thereby increasing the temperature of the refrigerant. The other energy conversion structure 61 corresponds to the other heat storage structure 62, and the energy conversion and transmission process between them can be referred to the above, which will not be described here.

[0041] The two heat storage structures 62 are provided with a heat transfer pipeline 63. When the heat transfer pipeline 63 is connected, the heat of the heat storage structure 62 with a higher temperature can be transmitted to the heat storage structure 62 with a lower temperature through the heat transfer pipeline 63, thereby achieving the purpose of balancing the temperatures of the two heat storage structures 62.

[0042] In combination with Figure 4 andFigure 5 As shown, the energy conversion structure 61 comprises: a micro generator 611 and a rotor 612. The rotor 612 is rotatably connected with the connecting plate 42 on the same side of the rotor 612. For example, the rotor 612 is located below the mounting hole 411, and the rotor 612 is connected with the connecting plate 42 below the mounting hole 411. The rotor 612 conforms to the Magnus effect. The rotor 612 is connected with the micro generator 611 through a transmission mechanism (not shown in the figure). It should be noted that the rotation of the rotor 612 to generate electricity is a prior art, which will not be described here.

[0043] The surface patterns, shapes and / or structures of the rotors 612 of the two heat storage structures 62 are different, so that the rotation efficiencies of the two rotors 612 are different. At the same time, the saturation heat of the heat storage rods 621 is different, so that the saturation speeds of the two heat storage rods 621 are different. The saturation heat of one of the heat storage rods 621 is larger, and corresponds to the rotor 612 with low rotation efficiency. In this way, the heat storage rod 621 can always be in an unsaturated state during the entire heat storage process, that is, the heat storage rod 621 is a constant unsaturated heat storage rod.

[0044] Again referring to Figure 4 and Figure 5 The heat storage structure 62 comprises: a heat storage rod 621 and a heat conduction plate 622. The heat storage rod 621 is connected with the micro generator 611. The micro generator 611 uses electric energy to heat the heat storage rod 621. The heat storage rod 621 is connected with the heat conduction plate 622 to transfer heat energy to the heat conduction plate 622. The heat conduction plate 622 is in contact with the outdoor heat exchanger 20, so as to conduct heat to the outdoor heat exchanger 20. Optionally, the heat conduction plate 622 is a fin heat conduction plate. The heat conduction plate 622 is connected with the heat storage rod 621 in the length direction of each to increase the contact area of the heat conduction plate 622 and the heat storage rod 621, so as to improve the heat transfer efficiency. The fin part of the heat conduction plate 622 is in contact with the outdoor heat exchanger 20 to improve the heat conduction effect.

[0045] The heat transfer pipeline 63 comprises: a heat transfer pipe 631 and an on-off valve 632. Two ends of the heat transfer pipe 631 are respectively connected with the two heat storage structures 62. Specifically, one end of the heat transfer pipe 631 is inserted into one of the heat storage rods 621, and the other end of the heat transfer pipe 631 is inserted into the other heat storage rod 621. The heat transfer pipe 631 is filled with refrigerant. The on-off valve 632 is arranged on the heat transfer pipe 631. When the on-off valve 632 is opened, the heat transfer pipe 631 is in a connected state. The heat of the heat storage rod 621 is transferred through the refrigerant in the heat transfer pipe 631, so as to balance the temperatures of the two heat storage rods 621.

[0046] The air conditioner further comprises: a stop component 70. The stop component 70 is arranged on the fan bracket 40 and located between the two rotors 612, and is used to stop the rotation of the rotor 612.

[0047] Optionally, the stop component 70 comprises a stop plate 71, a bracket 72 and a motor 73. The bracket 72 is slidably arranged on the connecting plate 42. Optionally, the bracket 72 is slidably connected with the connecting plate 42 through a slide rail or the like. The stop plate 71 is connected with the top of the bracket 72. The surface of the stop plate 71 is provided with a rack. The motor 73 is provided with a gear, and the gear is engaged with the rack.

[0048] When the rotor 612 needs to rotate, the stop plate 71 is located at the first position. At this time, the stop plate 71 does not contact with the rotors 612 on both sides. When the outdoor fan 30 rotates, the wind blown by the outdoor fan 30 can drive the rotors 612 to rotate. Since the rotors 612 conform to the Magnus effect, the rotors 612 can serve as a power source for the corresponding micro generator 611 to generate electricity. The wind energy is converted into electric energy through the rotation of the rotors 612. The electric energy generated by the micro generator 611 makes the heat storage rod 621 heat up. The heat storage rod 621 transmits heat to the heat conduction plate 622. The heat conduction plate 622 further transmits heat to the outdoor heat exchanger 20. When the rotors 612 do not need to rotate, the motor 73 is controlled to rotate, thereby driving the stop plate 71 to move towards the target rotor. The stop plate 71 is brought into contact with the target rotor, thereby reducing the rotation speed of the target rotor or stopping the rotation of the target rotor.

[0049] Optionally, one wall surface of the outer casing 10 is provided with an air outlet. The air outlet corresponds to the air outlet side of the outdoor fan 30. The air guide ring 90 is located inside the outer casing 10 and is arranged corresponding to the air outlet.

[0050] In combination Figure 6 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0051] S601, the air conditioner acquires its operation mode.

[0052] S602, the air conditioner acquires its operation state when the operation mode is a heating mode.

[0053] S603, the air conditioner controls the operation of the energy conversion structure and the heat transfer pipeline according to the operation state.

[0054] When the air conditioner defrosts, the four-way valve is generally controlled to reverse, so that the cold medium with a higher temperature enters the outdoor heat exchanger, thereby achieving the purpose of defrosting the outdoor heat exchanger. When the air conditioner operates in a heating mode, the indoor heat exchanger is a condenser, and the outdoor heat exchanger is an evaporator. The evaporator needs to absorb heat when evaporating the cold medium. After absorbing heat, the temperature of the outdoor heat exchanger decreases, and the air outside encounters the cooler outdoor heat exchanger to form condensed water. When the air conditioner operates in a heating mode, the outdoor temperature is generally low. Therefore, the condensed water will become frost, thereby causing the outdoor heat exchanger to frost. Therefore, when the air conditioner operates in a heating mode and frost, defrosting is needed. Conversely, when the air conditioner operates in a cooling mode, defrosting is not needed.

[0055] In the process of running the air conditioner, the running mode of the air conditioner is acquired. Here, the main distinction is between the cooling mode and the heating mode. If the air conditioner runs in the heating mode, the running state of the air conditioner is further acquired. To determine whether the air conditioner is in the defrosting stage. Then, according to the running state of the air conditioner, the running of the energy conversion structure and the heat transfer pipeline is controlled. As described in the foregoing, when the energy conversion structure runs, the wind energy generated by the running of the outdoor fan can be converted into heat energy. The heat transfer pipeline has two running states of being connected and being disconnected. When the heat transfer pipeline is connected, the heat storage amount of the two heat storage rods can be balanced. When the air conditioner does not enter the defrosting, the heat storage structure needs to be controlled to store heat. When the air conditioner enters the defrosting, the temperatures of the two heat storage rods need to be controlled to be close, so as to assist in uniform defrosting of the outdoor heat exchanger.

[0056] In the embodiments of the present disclosure, first, the running mode of the air conditioner is determined to determine whether there will be a demand for defrosting. When the air conditioner runs in the heating mode, the running state of the air conditioner is further determined to determine whether the air conditioner enters the defrosting. Then, based on the running state of the air conditioner, the running of the energy conversion structure and the heat transfer pipeline is controlled. To make the running state of the energy conversion structure and the on-off state of the heat transfer pipeline meet the state required by the normal running of the air conditioner in the heating mode or the running of the air conditioner in the defrosting stage. When the energy conversion structure runs, the wind energy generated by the running of the outdoor fan can be converted into heat energy, and the heat energy is conducted to the corresponding heat storage structure. The heat storage structure further conducts the heat to the outdoor heat exchanger to improve the temperature of the refrigerant. If the air conditioner does not enter the defrosting, conducting the heat to the outdoor heat exchanger can improve the evaporation temperature of the outdoor heat exchanger, thereby improving the heating effect. If the air conditioner enters the defrosting, conducting the heat to the outdoor heat exchanger can assist in defrosting, thereby improving the defrosting effect. Moreover, the heat conducted by the heat storage structure to the outdoor heat exchanger is derived from the conversion of the wind energy generated by the running of the outdoor fan. The wind energy generated by the running of the outdoor fan is fully utilized, and energy saving is achieved.

[0057] In combination with Figure 7 As shown in the figure, the embodiments of the present disclosure provide another method for controlling an air conditioner, comprising:

[0058] S601, the air conditioner acquires its running mode.

[0059] S612, the air conditioner acquires the rotation speed of its outdoor fan in the case that the running mode is the heating mode.

[0060] S613, the air conditioner controls the energy conversion structure to start running to make the corresponding heat storage structure start storing heat in the case that the rotation speed of the outdoor fan is stable; and controls the heat transfer pipeline to be connected.

[0061] The running state of the air conditioner includes the rotating speed of the outdoor fan. The rotation of the rotor depends on the air volume generated by the running of the outdoor fan. When the outdoor fan is just started, the air speed is generally small and is not enough to make the rotor rotate. With the increase of running time, the rotating speed of the outdoor fan gradually stabilizes and reaches the maximum value that can be reached at present. At this time, the energy conversion controlled to start running to convert wind energy into heat energy. Specifically, the stop component is controlled not to brake the rotor, that is, the stop plate is located in the first position. At this time, the stop plate is located between the two rotors and does not contact the two rotors, and the rotor can rotate normally.

[0062] Because the rotating efficiency of the two rotors is different, the converted heat energy is also different, and the heat storage speed of the heat storage rod is also different. Therefore, while controlling the energy conversion structure to start running, the on-off valve is controlled to be opened, so as to control the heat transfer pipeline to be communicated. After the heat transfer pipeline is communicated, the temperature of the two heat storage rods is balanced by the refrigerant in the heat transfer pipeline. In this way, the heat storage rod with slow heat storage can be heated up as soon as possible.

[0063] But in the process of energy conversion, it is necessary to ensure that there is a heat storage temperature difference between the two heat storage rods, that is, the heat storage amount of the two heat storage rods is different. If there is no temperature difference between the two heat storage rods, the target rotor is determined, and the stop component is controlled to stop the target rotor. The rotating speed of the target rotor is reduced or stopped, so as to create a temperature difference. Alternatively, the target rotor can be the rotor with a longer cumulative rotation time. In this way, the rotor with a longer cumulative rotation time is slowed down or stopped to reduce the wear of the rotor.

[0064] Optionally, the air conditioner controls the stop component to stop the target rotor, specifically: according to the target rotor, the target rotating direction of the motor is determined. For the two rotors of the same conversion heat conduction mechanism, one rotor (for example, the left rotor) is the first rotor, and the other rotor (for example, the right rotor) is the second rotor. If the target rotor is the first rotor, the target rotating direction is determined to be forward rotation. When the stop plate is located at the second position, the stop plate is in light contact with the first rotor, and the rotating speed of the first rotor is reduced but can continue to rotate. When the stop plate is located at the third position, the stop plate is in deep contact with the first rotor, and the first rotor stops rotating. If the target rotor is the second rotor, the target rotating direction is determined to be reverse rotation. When the stop plate is located at the fourth position, the stop plate is in light contact with the second rotor, and the rotating speed of the second rotor is reduced but can continue to rotate. When the stop plate is located at the fifth position, the stop plate is in deep contact with the second rotor, and the second rotor stops rotating. First, the stop plate is controlled to be in light contact with the target rotor, so that the rotating speed of the target rotor is reduced. After a preset time, the temperature of the two heat storage rods is detected by the temperature sensor arranged on the heat storage rod. The temperature sensor is in communication connection with the processor of the air conditioner. The processor calculates the temperature difference between the two heat storage rods according to the temperature detected by the temperature sensor. If the temperature difference is greater than or equal to the temperature threshold value, the stop plate is controlled to remain at the current position. If the temperature difference is less than the temperature threshold value, it indicates that the effect of manufacturing the temperature difference by reducing the rotating speed of the rotor is not obvious. At this time, the target position of the stop plate is determined according to the target rotor. As described above, if the target rotor is the first rotor, the target position is the third position. If the target rotor is the second rotor, the target position is the fifth position. The motor is controlled to rotate to drive the stop plate to the target position. The stop plate is in deep contact with the target rotor, so that the target rotor stops rotating. In this way, by controlling the target rotor to stop rotating, the temperature difference between the two heat storage rods is further expanded.

[0065] After the temperature difference is greater than or equal to the temperature threshold value, the motor is controlled to reverse to move the stop plate to the first position, and the brake on the target rotor is released.

[0066] In combination Figure 8 As shown in the drawings, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:

[0067] S601, the air conditioner obtains its operating mode.

[0068] S612, the air conditioner obtains the rotating speed of its outdoor fan and the heat storage amount of the heat storage structure in the case of the operating mode being the heating mode.

[0069] S613, the air conditioner controls the energy conversion structure to start operating to make the corresponding heat storage structure start heat storage in the case of the rotating speed of the outdoor fan being stable; and controls the heat transfer pipeline to be communicated.

[0070] S623, the air conditioner controls the heat transfer pipeline to be disconnected when the heat storage amount of any one of the heat storage structures reaches the saturated heat amount.

[0071] S633, the air conditioner controls the stop component to stop the rotor corresponding to the heat storage structure.

[0072] After the heat storage starts, the temperature of the heat storage rod is detected by the temperature sensor. When the temperature tends to be stable, it indicates that the heat storage amount of the heat storage structure, i.e., the heat storage rod, reaches the saturated heat amount, and the heat storage rod completes the heat storage. When the heat storage amount of any one of the heat storage rods reaches the saturated heat amount first, the on-off valve is controlled to be closed, so as to control the heat transfer pipeline to be disconnected. Because, at this time, one heat storage rod has completed the heat storage, and the temperature of the heat storage rod can be used to provide a higher temperature for the outdoor heat exchanger, and there is no need to use the refrigerant to accelerate the heat storage temperature of another heat storage rod. Therefore, the heat transfer pipeline can be controlled to be disconnected.

[0073] Because the heat storage rod completes the heat storage, the stop component is controlled to stop the rotor corresponding to the heat storage rod. The corresponding rotor is stopped to stop the heat storage. Specifically, the rotor corresponding to the heat storage rod that completes the heat storage is determined as a target rotor. Then, the target rotation direction of the motor and the target position of the stop plate are determined according to the target rotor, i.e., whether the third position or the fifth position is determined. The specific determination method can be referred to the foregoing, and will not be described here. Then, the motor is controlled to rotate according to the target rotation direction, and drives the stop plate to move to the target position.

[0074] In the process of the heat storage of the heat storage structure, the heat conduction plate also conducts heat to the outdoor heat exchanger, which can improve the heating effect and make the energy be fully utilized.

[0075] In combination with Figure 9 As shown in FIG. 1, the embodiment of the present disclosure provides another method for controlling an air conditioner, which comprises the following steps:

[0076] S601, the air conditioner obtains the operation mode thereof.

[0077] S612, the air conditioner obtains the rotation speed of the outdoor fan, the heat storage amount of the heat storage structure, and the defrosting condition of the air conditioner when the operation mode is the heating mode.

[0078] S613, the air conditioner controls the energy conversion structure to start operating to make the corresponding heat storage structure start heat storage when the rotation speed of the outdoor fan is stable, and controls the heat transfer pipeline to be connected.

[0079] S623, the air conditioner controls the heat transfer pipeline to be disconnected when the heat storage amount of any one of the heat storage structures reaches the saturated heat amount.

[0080] S633, the air conditioner controls the stop component to stop the rotor corresponding to the heat storage structure.

[0081] S643, after the air conditioner executes S623, in the case of defrosting, the heat transfer pipe is connected.

[0082] After the heat storage structure completes heat storage, the air conditioner is determined whether to enter defrosting according to the defrosting condition of the air conditioner. Alternatively, if the air conditioner performs sensible heat defrosting, it can be determined whether the air conditioner enters defrosting by determining whether the four-way valve is reversed. If the air conditioner performs latent heat defrosting, it can be determined whether the air conditioner enters defrosting by determining whether the relevant defrosting pipe is connected. If it is determined that the air conditioner enters defrosting, the on-off valve is controlled to be opened, so as to control the heat transfer pipe to be connected. In this way, the heat of the heat storage rod with higher temperature can be transferred to the heat storage rod with lower temperature through the refrigerant in the heat transfer pipe, so as to balance the temperature of the two heat storage rods. In this way, the heat conduction of the two heat storage structures to the outdoor heat exchanger tends to be consistent, thereby improving the defrosting efficiency.

[0083] During the defrosting process, the heat conduction plate conducts heat to the outdoor heat exchanger, thereby increasing the temperature of the outdoor heat exchanger and improving the defrosting effect.

[0084] For the two rotors of the same conversion heat conduction mechanism, whether the heat storage structure is in heat storage or enters defrosting, only one rotor is allowed to stop rotating. As described above, when the heat storage rod with small saturated heat reaches the saturated heat, the corresponding rotor stops rotating. The other heat storage rod is in a constant unsaturated state, so its corresponding rotor always rotates.

[0085] The rotor with high rotation efficiency collects heat quickly, and in the defrosting process, the heat of the corresponding heat storage rod can be utilized first. When the heat is used up, the heat of the other heat storage rod is just increased to a high level, which can be utilized. In this way, through the two rotors with different rotation efficiencies, the heat storage amounts of the two heat storage rods are different, that is, a temperature difference is generated between the two heat storage rods, so that the two heat storage structures are alternately heat exchanged with the outdoor heat exchanger, and the entire conversion heat conduction mechanism can always output heat to the outdoor heat exchanger.

[0086] In combination Figure 10 As shown in the figure, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:

[0087] S601, the air conditioner obtains its operating mode.

[0088] S612, the air conditioner obtains the speed of its outdoor fan in the case of the operating mode being a heating mode.

[0089] S622, the air conditioner determines the target rotor in the case of the operating mode being a cooling mode.

[0090] S613, after the air conditioner executes S612, in the case that the rotating speed of the outdoor fan is stable, the energy conversion structure is controlled to start running so that the corresponding heat storage structure starts to store heat; and the heat transfer pipeline is connected.

[0091] S623, after the air conditioner executes S613, in the case that the heat storage amount of any one heat storage structure reaches its saturated heat amount, the heat transfer pipeline is disconnected.

[0092] S633, after the air conditioner executes S623, the stop component is controlled to stop the rotor corresponding to the heat storage structure.

[0093] S635, after the air conditioner executes S622, the stop component is controlled to stop the target rotor.

[0094] As described above, when the air conditioner runs in the cooling mode, the outdoor heat exchanger is a condenser, and it is not necessary to increase the heat exchange temperature or defrost. Therefore, when the air conditioner runs in the cooling mode, the target rotor is determined. Then the stop component is controlled to stop the target rotor. Specifically, among the two rotors, the rotor with a longer cumulative running time is determined as the target rotor. Then, according to the target rotor, the target rotating direction of the target motor and the target position of the stop plate are determined, i.e., whether the third position or the fifth position is determined. The specific determination method can be referred to the foregoing, and will not be described here. Then the motor is controlled to rotate according to the target rotating direction, and the stop plate is driven to move to the target position. In this way, the target rotor is controlled to stop rotating, which not only prolongs the service life of the rotor, but also reduces the noise generated during the operation of the rotor.

[0095] Optionally, before defrosting, the rotating speed V of the outdoor fan and the indoor temperature T1 are recorded. During the current defrosting process, the indoor temperature is obtained, and the lowest indoor temperature T min is recorded. It is determined whether T1-T min >ΔT, where ΔT is a temperature difference threshold. If it is satisfied, it means that the indoor temperature during the defrosting process is less than the indoor temperature before the defrosting too much, and the indoor temperature is low. Therefore, when the defrosting is completed and the heating is resumed, it is necessary to increase the heating capacity to compensate for the impact of the defrosting on the indoor temperature. However, increasing the heating capacity will accelerate the frosting speed of the outdoor heat exchanger. In this case, after the current defrosting is completed, the rotating speed Vi of the outdoor fan is obtained. When Vi=V, it means that the rotating speed of the outdoor fan reaches the rotating speed before the defrosting. At this time, even if the preset defrosting temperature and time are not reached, it is determined that the air conditioner enters the defrosting process. The defrosting is controlled to enter, and the operation of the heat transfer pipeline is controlled according to the logic described above. In this way, the air conditioner is controlled to enter the defrosting process in advance, so as to avoid that the outdoor heat exchanger is seriously frosted to affect the normal operation of the air conditioner, or that the indoor temperature fluctuates too much when the outdoor heat exchanger is defrosted when it is seriously frosted.

[0096] In combination with Figure 11As shown, the embodiment of the present disclosure provides a device for controlling an air conditioner, comprising a first obtaining module 111, a second obtaining module 112 and a control module 113. A module 21, a module 22 and a module 23. The first obtaining module 111 is configured to obtain the running mode of the air conditioner. The second obtaining module 112 is configured to obtain the running state of the air conditioner in the case that the running mode is the heating mode. The control module 113 is configured to control the running of the energy conversion structure and the heat transfer pipeline according to the running state of the air conditioner.

[0097] By using the device for controlling an air conditioner provided by the embodiment of the present disclosure, firstly, the running mode of the air conditioner is judged to determine whether there will be a need for defrosting. In the case that the air conditioner runs in the heating mode, the running state of the air conditioner is further determined to determine whether the air conditioner enters defrosting. Then, based on the running state of the air conditioner, the running of the energy conversion structure and the heat transfer pipeline is controlled. So that the running state of the energy conversion structure and the on-off state of the heat transfer pipeline meet the state required by the air conditioner running in the heating mode or running in the defrosting phase. When the energy conversion structure runs, the wind energy generated by the outdoor fan running can be converted into heat energy, and the heat energy is conducted to the corresponding heat storage structure. The heat storage structure further conducts the heat to the outdoor heat exchanger to improve the temperature of the refrigerant. If the air conditioner does not enter defrosting, conducting heat to the outdoor heat exchanger can improve the evaporation temperature of the outdoor heat exchanger, thereby improving the heating effect. If the air conditioner enters defrosting, conducting heat to the outdoor heat exchanger can assist defrosting, thereby improving the defrosting effect. Moreover, the heat conducted by the heat storage structure to the outdoor heat exchanger is derived from the conversion of the wind energy generated by the outdoor fan running. The wind energy generated by the outdoor fan running is fully utilized, and energy saving is achieved.
