Description

Technical Field

[0001] This invention relates to the field of electrical technology, and in particular to air conditioning systems, control methods for air conditioning systems, and their electrical control devices. Background Technology

[0002] In related technologies, outdoor temperatures in most areas drop below 0°C in winter, causing air conditioner outdoor units to operate at sub-0°C ambient temperatures for extended periods. During rainy or snowy weather, combined with ambient temperatures below 0°C, the chassis and heat exchanger surfaces of the outdoor unit are highly susceptible to icing, affecting heat exchange efficiency and potentially causing quality or safety hazards. The condenser defrosting and de-icing process involves the compressor running when the outdoor unit starts up. Upon detecting an ambient temperature below 0°C, the four-way valve reverses, allowing high-temperature, low-pressure refrigerant to flow through the heat exchanger for heat dissipation. Simultaneously, the outdoor unit fan reverses direction to defrost and de-ic the heat exchanger. After the frost melts, a small portion evaporates, while the majority flows to the chassis as liquid water. Due to the sub-0°C ambient temperature, most of this water freezes on the chassis. As the ice layer blocks the drain holes, it accumulates. If not de-iced promptly, the ice layer can interfere with the fan's rotation, potentially breaking the fan. Fan fragments can then be ejected from the outdoor unit's air chamber, posing a safety hazard.

[0003] Currently, de-icing of the outdoor unit chassis is commonly achieved by adding an electric heating device. These devices are typically powered by industrial or household electricity, resulting in high power consumption and inefficiency. A smaller number use solar panels for charging. However, these solar panels are generally fixed in place, making it impossible to maintain perfect alignment with sunlight, leading to slow charging efficiency and poor practicality. Summary of the Invention

[0004] This invention provides an air conditioning system, a control method for the air conditioning system, and an electrical control device thereof, to overcome the deficiencies in the prior art and achieve the following technical effects: by converting solar energy into electrical energy to power an electric heating device, and by enabling the solar panel to charge the battery at a high or even maximum charging efficiency, the original power consumption method is replaced by green and environmentally friendly solar power, thus realizing the effective use of clean energy and reducing the energy consumption of the entire air conditioning system.

[0005] An air conditioning system according to a first aspect of the present invention includes:

[0013] According to one embodiment of the present invention, there are multiple solar panels, multiple control linkage devices, and multiple outdoor units, and each solar panel is installed on the outdoor unit in a one-to-one correspondence with one of the control linkage devices.

[0014] According to one embodiment of the present invention, there are multiple batteries, and each of the multiple batteries corresponds to a multiple of the solar panels and a multiple of the outdoor units; the electronic control device is used to control the battery corresponding to another adjacent outdoor unit to charge the battery when it detects that the power of the battery corresponding to one of the outdoor units is lower than a set power.

[0015] Alternatively, the number of batteries is one, and all the solar panels are electrically connected to the batteries. The electronic control device is used to control the solar panels to charge the batteries when the total charge of the batteries is detected to be lower than a set charge.

[0017] Obtain the battery's charge level;

[0018] When the battery charge is determined to be lower than the set charging charge, the solar panel is controlled to enter the charging state, and the current position information of the sun relative to the solar panel is obtained.

[0019] During the charging state, the control linkage device is activated based on the sun's position information to ensure that the solar panel is perpendicular to the current sun's direction.

[0020] According to one embodiment of the present invention, the illumination position information includes the solar illumination elevation angle and the solar illumination azimuth angle;

[0021] The step of controlling the operation of the control linkage device based on the sun's position information during the charging state specifically includes:

[0022] During the charging state, the drive cylinder is controlled to adjust the height angle of the solar panel according to the solar illumination angle, until the height angle of the solar panel is equal to the illumination angle.

[0023] During the charging state, the drive motor is controlled to operate according to the azimuth angle of the sun's illumination, so as to adjust the azimuth angle of the solar panel until the azimuth angle of the solar panel is equal to the illumination azimuth angle.

[0024] According to one embodiment of the present invention, the number of the storage battery, the solar panel and the outdoor unit are all multiple in a one-to-one correspondence;

[0025] The control method further includes:

[0026] Obtain the battery level corresponding to each outdoor unit;

[0027] When the battery level of one of the indoor units is found to be lower than the minimum set battery level, the system controls the battery of the adjacent outdoor unit to charge it.

[0028] According to one embodiment of the present invention, the control method of the air conditioning system further includes:

[0029] Obtain the chassis temperature of the outdoor unit;

[0030] If the chassis temperature is determined to be lower than a first set temperature and the battery charge is greater than a first set discharge charge, the electric heating device is controlled to turn on and powered by the battery to heat the chassis of the outdoor unit.

[0031] According to one embodiment of the present invention, the number of the storage battery, the solar panel, the outdoor unit and the electric heating device are all one-to-one multiple;

[0033] If it is determined that the chassis temperature of one of the outdoor units is lower than the first set temperature, and the battery power corresponding to that outdoor unit is less than or equal to the second set discharge power, then the battery corresponding to the outdoor unit adjacent to that outdoor unit is controlled to supply power to the electric heating device of that outdoor unit, so that the electric heating device heats the chassis of that outdoor unit.

[0034] According to one embodiment of the present invention, after the step of controlling the electric heating device to turn on and supplying it with power by a storage battery, the control method of the air conditioning system further includes:

[0039] The second control module is used to control the control linkage device to operate according to the sun's position information during the charging state, so that the solar panel is perpendicular to the current sun's direction.

[0040] This invention proposes an air conditioning system, its control method, and an electronic control device. A solar panel is added to the outside of the outdoor unit to charge a storage battery, which in turn powers an electric heating device. The electric heating device is then controlled to heat the chassis of the outdoor unit to achieve the de-icing process. No other industrial or household electricity input is required; instead, solar energy is converted into electricity to power the electric heating device. This green and environmentally friendly use of solar energy replaces the original electricity consumption method, achieving effective utilization of clean energy and reducing the overall energy consumption of the air conditioning system.

[0041] In addition, during the process of the solar panel charging the battery, the electronic control device can adjust the position and angle of the solar panel by adjusting the action of the control linkage device, so that the solar panel can always face or even be perpendicular to the direction of sunlight, ensuring that the solar panel can always charge the battery with high or even maximum charging efficiency. It is highly practical and can be applied to various weather conditions and terrain conditions. Attached Figure Description

[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0058] like Figures 1 to 8 As shown, an air conditioning system according to a first aspect embodiment of the present invention includes an indoor unit (not shown), at least one outdoor unit 1, a solar panel 2, a battery 3, and an electronic control device 4.

[0059] The outdoor unit 1 is equipped with an electric heating device (not shown in the figure) for defrosting the ice inside the outdoor unit 1. For example, the electric heating device is installed at the chassis of the outdoor unit 1.

[0060] The solar panel 2 is electrically connected to the battery 3 for charging, and the battery 3 is electrically connected to the electric heating device for power supply. The solar panel 2 is installed on the outside of the outdoor unit 1 through a control linkage device to achieve adjustable azimuth and elevation angles.

[0061] The electronic control device 4 is connected to the control linkage device. The electronic control device 4 is used to obtain the position information of the sun and control the action of the control linkage device according to the position information of the sun to adjust the azimuth and elevation angle of the solar panel 2.

[0062] According to an embodiment of the present invention, the specific working process of the air conditioning system is as follows: For the solar panel 2 and the battery 3 of the system, there are two working stages, namely the charging stage and the discharging stage.

[0063] During the charging phase, the electronic control device 4 obtains the position information of the sun relative to the solar panel 2 through the positioning module, and further controls and adjusts the control linkage device based on the sun's position information. This causes the control linkage device to move, thereby adjusting the azimuth and elevation angles of the solar panel 2. By adjusting the azimuth and elevation angles of the solar panel 2, the solar panel 2 can always face the direction of sunlight, ensuring that it receives good sunlight conditions during the charging phase and guaranteeing solar charging efficiency. Furthermore, during the adjustment process of the solar panel 2, the position information of the sun can be used to adjust the solar panel 2 to a position that is always perpendicular to the direction of sunlight, thereby further improving the solar charging efficiency and achieving maximum charging efficiency for the battery 3.

[0064] During the discharge phase, when the air conditioning system starts in heating mode, icing may occur on the bottom chassis of outdoor unit 1. Therefore, after outdoor unit 1 starts, the electronic control device 4 obtains the chassis temperature of outdoor unit 1 through a temperature sensor installed on the chassis. When the electronic control device 4 detects that the chassis temperature of outdoor unit 1 is lower than the set entry temperature, it indicates that there is a risk of icing or that icing has already occurred on the chassis of outdoor unit 1. Therefore, in order to avoid or eliminate icing on the chassis of outdoor unit 1, the electronic control device 4 controls the battery 3 to discharge the electric heating device and simultaneously turns on the electric heating device, so that the electric heating device heats the chassis of outdoor unit 1, thereby eliminating the frost condensed on the chassis of outdoor unit 1. During the heating process, if the electronic control device 4 further detects that the chassis temperature of outdoor unit 1 has been heated to the set exit temperature, the electronic control device 4 controls the battery 3 to disconnect the power supply to the electric heating device, thereby completing the de-icing process of outdoor unit 1.

[0065] In related technologies, outdoor temperatures in most areas drop below 0°C in winter, causing air conditioner outdoor units to operate at sub-0°C ambient temperatures for extended periods. During rainy or snowy weather, combined with ambient temperatures below 0°C, the chassis and heat exchanger surfaces of the outdoor unit are highly susceptible to icing, affecting heat exchange efficiency and potentially causing quality or safety hazards. The condenser defrosting and de-icing process involves the compressor running when the outdoor unit starts up. Upon detecting an ambient temperature below 0°C, the four-way valve reverses, allowing high-temperature, low-pressure refrigerant to flow through the heat exchanger for heat dissipation. Simultaneously, the outdoor unit fan reverses direction to defrost and de-ic the heat exchanger. After the frost melts, a small portion evaporates, while the majority flows to the chassis as liquid water. Due to the sub-0°C ambient temperature, most of this water freezes on the chassis. As the ice layer blocks the drain holes, it accumulates. If not de-iced promptly, the ice layer can interfere with the fan's rotation, potentially breaking the fan. Fan fragments can then be ejected from the outdoor unit's air chamber, posing a safety hazard.

[0066] Currently, de-icing of the outdoor unit chassis is commonly achieved by adding an electric heating device. These devices are typically powered by industrial or household electricity, resulting in high power consumption and inefficiency. A smaller number use solar panels for charging. However, these solar panels are generally fixed in place, making it impossible to maintain perfect alignment with sunlight, leading to slow charging efficiency and poor practicality.

[0067] Therefore, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention proposes an air conditioning system in which a solar panel 2 is added to the outside of the outdoor unit 1. The solar panel 2 is used to charge the battery 3 and the battery 3 supplies power to the electric heating device. The electric heating device is controlled to heat the chassis of the outdoor unit 1 to realize the de-icing process of the outdoor unit 1. No other industrial or household electricity input is required. Instead, solar energy is converted into electrical energy to power the electric heating device. The green and environmentally friendly solar power replaces the original power consumption method, realizes the effective use of clean energy, and reduces the energy consumption of the entire air conditioning system.

[0068] In addition, during the process of the solar panel 2 charging the battery 3, the electronic control device 4 can adjust the position and angle of the solar panel 2 by adjusting the action of the control linkage device, so that the solar panel 2 can always face or even be perpendicular to the direction of sunlight, ensuring that the solar panel 2 can always charge the battery 3 with high or even maximum charging efficiency. It is highly practical and can be applied to various weather conditions and terrain conditions.

[0069] For the control linkage device of the present invention, it needs to adjust the azimuth and elevation angles of the solar panel 2. Therefore, the control linkage device is equipped with two driving components. One driving component is used to rotate the solar panel 2 to adjust its azimuth angle, and the other driving component is used to adjust its vertical height and tilt angle to adjust its elevation angle. It can be understood that both driving components can be linear driving components (such as hydraulic cylinders or pneumatic cylinders), both can be rotary driving components (such as motors), or one can be a linear driving component and the other can be a rotary driving component. In this case, under different combinations of driving component types, the two driving components can achieve the above two aspects of adjustment through different transmission components. For example, transmission components include, but are not limited to, worm gear 56 structures, connecting rod structures, hinge structures, lead screw and nut structures, etc. Therefore, the present invention does not specifically limit the types of the two driving components, nor does it specifically limit the structure of the transmission components connected to the driving components, as long as the above linkage control device can achieve the adjustment of the azimuth and elevation angles of the solar panel 2.

[0070] The following describes a specific structure of the control linkage device in the air conditioning system of the present invention.

[0071] like Figures 3 to 6As shown, according to a specific embodiment of the present invention, the control linkage device includes a first bracket 51, a drive cylinder 52, a second bracket 53, a drive motor 54, and a third bracket 55.

[0072] The first bracket 51 is fixed to the outer casing of the outdoor unit 1, the cylinder part of the drive cylinder 52 is rotatably connected to the first bracket 51, and the drive part of the drive cylinder 52 is rotatably connected to the second bracket 53.

[0073] The third bracket 55 is sleeved on the outside of the second bracket 53. The drive motor 54 is fixed to the third bracket 55, and the drive motor 54 drives the third bracket 55 to rotate relative to the second bracket 53 through the worm gear 56 structure. The solar panel 2 is fixed to the third bracket 55.

[0074] Thus, when the drive motor 54 starts, the drive motor 54 can drive the third bracket 55 to rotate horizontally relative to the second bracket 53 through the worm gear 56 structure. That is, it controls the solar panel 2 to rotate horizontally to face different directions. It can be understood that the purpose of the above process of controlling the drive motor 54 is to adjust the azimuth angle of the solar panel 2, that is, to make the solar panel 2 face different directions (such as east, south, west, north, etc.).

[0075] When the drive cylinder 52 is activated, its driving part pushes the second bracket 53 to move forward and upward or backward and downward in an arc-shaped trajectory. At this time, the second bracket 53 drives the third bracket 55 to move, which in turn drives the solar panel 2 to move forward and upward or backward and downward, thereby changing the height of the solar panel 2 and the angle between the solar panel 2 and the horizontal plane. This achieves the control and adjustment of the solar panel 2's height angle. It can be understood that the purpose of the above-described process of controlling the drive cylinder 52 is to achieve the adjustment of the solar panel 2's height angle.

[0076] For example, the first bracket 51 is a triangular frame bracket. The bottom of the first bracket 51 is fixed to the top cover of the outdoor unit 1 by six screws. The cylinder part of the drive cylinder 52 is hinged to the first bracket 51. The drive part of the drive cylinder 52 is rotatably connected to the second bracket 53. The upper part of the second bracket 53 forms a cylindrical first sleeve part. The third bracket 55 forms a ring-shaped second sleeve part that matches the shape of the first sleeve part. The second sleeve part of the third bracket 55 is rotatably disposed on the outside of the first sleeve part of the second bracket 53 through the first bearing 58. The third bracket 55 is also provided with a drive motor 54. The drive motor 54 is connected to a worm gear 56. The worm gear 56 drives the third bracket 55 to rotate around the turbine 57 under the support of the second bearing 59, and synchronously drives the third bracket 55 to rotate around the second bracket 53.

[0077] The solar panel 2 is fixed on the third bracket 55. At this time, the solar panel 2 can adjust its height angle under the action of the drive cylinder 52, and adjust its azimuth angle under the action of the drive motor 54.

[0078] According to some embodiments of the present invention, the electronic control device 4 is connected to the drive cylinder 52 and the drive motor 54 respectively. The electronic control device 4 is used to control the drive motor 54 to adjust the azimuth angle of the solar panel 2 according to the azimuth angle information of the sun, and to control the drive cylinder 52 to adjust the altitude angle of the solar panel 2 according to the altitude angle information of the sun.

[0079] In this way, the electronic control device 4 continuously adjusts the azimuth and elevation angles of the solar panel 2 during the charging process of the battery 3, so that the azimuth angle of the solar panel 2 continuously approaches the azimuth angle of the sun's illumination, and the elevation angle of the solar panel 2 continuously approaches the elevation angle of the sun's illumination, ultimately achieving the technical effect that the solar panel 2 always remains perpendicular to the direction of the sun's illumination.

[0080] like Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, there are multiple solar panels 2, control linkage devices and outdoor units 1, and each solar panel 2 is installed on the outdoor unit 1 in a one-to-one correspondence with a control linkage device.

[0081] In this way, when there are multiple outdoor units 1, each outdoor unit 1 can utilize the solar panels 2 installed on it to realize the utilization of solar energy, thereby improving the efficiency of the entire system in absorbing solar energy and storing more electrical energy for the system.

[0082] According to some embodiments of the present invention, the number of batteries 3 in the entire air conditioning system can be one, two, or more. That is, multiple solar panels 2 can simultaneously power one battery 3, or multiple solar panels 2 can independently power multiple batteries 3. The present invention does not impose any special limitations.

[0083] For example, such as Figure 7 As shown, there are multiple batteries 3, and each battery 3 corresponds to a different solar panel 2 and an outdoor unit 1.

[0084] The electronic control device 4 is used to charge the battery 3 corresponding to the adjacent indoor unit when it detects that the power of the battery 3 corresponding to one of the indoor units is lower than the set power.

[0085] That is, in this embodiment, multiple solar panels 2 independently supply power to multiple batteries 3. In addition to charging the batteries 3 through the solar panels 2, the multiple batteries 3 can also be connected to each other to charge each other. Specifically, when one battery 3 is low on power, another one or two adjacent batteries 3 can charge the battery 3, thereby ensuring the healthy power of each battery 3 and avoiding affecting the subsequent defrosting and de-icing process.

[0086] Furthermore, when there are multiple batteries 3, each battery 3 corresponds to an electric heating device installed on a multiple outdoor unit 1. That is, each electric heating device is powered by a battery 3, so that the defrosting process of multiple electric heating devices is independent of each other, avoiding the impact of insufficient power of one battery 3 on the power supply process of other batteries 3 to other electric heating devices, and ensuring the stability of the system defrosting.

[0087] For example, such as Figure 8 As shown, there is one battery 3, and all solar panels 2 are electrically connected to the battery 3. The electronic control device 4 is used to control the solar panels 2 to charge the battery 3 when the total charge of the battery 3 is detected to be lower than the set charge.

[0088] That is, in this embodiment, multiple solar panels 2 charge the same battery 3 simultaneously, and when the battery 3 is low on power, the charging process is restarted. In this way, by having multiple solar panels 2 charge one battery 3 at the same time, the charging efficiency of the battery 3 can be greatly improved. Furthermore, when there is only one battery 3, since the system only needs to control the charging and discharging process of one battery 3, the control process within the system is simpler and more stable, ensuring the stability of the charging and discharging process of the battery 3 within the system.

[0089] Furthermore, when there is only one battery 3, the battery 3 is simultaneously connected to the electric heating devices of all indoor units, that is, the battery 3 simultaneously supplies power to all electric heating devices to ensure the smooth defrosting process of all outdoor units 1.

[0090] The control method and control device for the air conditioning system proposed in this invention are described below with reference to the accompanying drawings. Before providing a detailed description of the embodiments of this invention, the overall application scenario is first described. The air conditioning control method, control device, electronic device, and computer-readable storage medium of this invention can be applied locally to the air conditioner, to cloud platforms in the Internet field, or to other types of cloud platforms in the Internet field, or to third-party devices. These third-party devices may include various types such as mobile phones, tablets, laptops, in-vehicle computers, and other smart terminals.

[0091] The following description uses a control method applicable to air conditioning as an example. It should be understood that the control method of this embodiment can also be applied to cloud platforms and third-party devices. It should be noted that this control method is implemented based on the structure of the air conditioning system described above.

[0092] like Figure 9 As shown, a control method for an air conditioning system according to a second aspect embodiment of the present invention includes:

[0093] Step S1: Obtain the power level of battery 3;

[0094] Step S2: When it is determined that the battery 3 has a charge level lower than the set charging level, control the solar panel 2 to enter the charging state and obtain the current position information of the sun relative to the solar panel 2.

[0095] Step S3: In the charging state, based on the sun's position information, control the linkage device to make the solar panel 2 perpendicular to the current sun's direction.

[0096] According to the control method of the air conditioning system of the present invention, by controlling the associated linkage structure and hydraulic system, the solar panel 2 is always perpendicular to the sunlight, so as to charge the battery with the best efficiency and store electrical energy; furthermore, by discharging the battery, the electric heating device of the outdoor unit 1 of the air conditioner is powered on to realize intelligent refrigeration.

[0097] During the charging and discharging process of the aforementioned battery 3, the energy conversion initially involves converting solar energy into electrical energy, and then electrical energy into heat energy to achieve chassis de-icing, which greatly reduces energy consumption.

[0098] According to some embodiments of the present invention, the illumination position information includes the sun's illumination altitude angle and illumination azimuth angle. Therefore, in the charging state, the steps of controlling the operation of the control linkage device based on the sun's illumination position information specifically include:

[0099] In the charging state, the drive cylinder 52 is controlled to move according to the solar illumination angle to adjust the height angle of the solar panel 2 until the height angle of the solar panel 2 is equal to the illumination angle.

[0100] In the charging state, the drive motor 54 is controlled to operate according to the azimuth angle of the sun's illumination, so as to adjust the azimuth angle of the solar panel 2 until the azimuth angle of the solar panel 2 is equal to the illumination azimuth angle.

[0101] In this way, by controlling the operation of the drive cylinder 52 and the drive motor 54 respectively, the azimuth angle of the solar panel 2 can be adjusted to be equal to the azimuth angle of the sun's illumination, and the altitude angle of the solar panel 2 can be adjusted to be equal to the altitude azimuth angle of the sun's altitude, so that the solar panel 2 remains perpendicular to the direction of the sun's illumination, and the battery 3 can always be charged at the maximum charging efficiency.

[0102] According to some embodiments of the present invention, such as Figure 7 As shown, the number of batteries 3, solar panels 2, and outdoor units 1 are all multiple in a one-to-one correspondence. Therefore, the control method also includes:

[0103] Obtain the battery level of each indoor unit;

[0104] When the battery 3 corresponding to one of the indoor units is found to be lower than the minimum set battery level, the battery 3 corresponding to the adjacent indoor unit is controlled to charge it.

[0105] In this way, when one of the batteries 3 is low on power, the other one or two adjacent batteries 3 can charge the battery 3, thereby ensuring the healthy power of each battery 3 and avoiding affecting the subsequent defrosting and de-icing process.

[0106] According to some embodiments of the present invention, the control method for an air conditioning system further includes:

[0107] Obtain the chassis temperature of outdoor unit 1;

[0108] If the chassis temperature is determined to be lower than the first set temperature and the battery 3 has a charge greater than the first set discharge charge, the electric heating device is turned on and powered by the battery 3 to heat the chassis of the outdoor unit 1.

[0109] It can be understood that the above process is the specific process steps for defrosting the chassis of the outdoor unit 1 in the air conditioning system. In the above steps, the battery 3 mainly plays the role of providing energy to the electric heating device.

[0110] According to some embodiments of the present invention, such as Figure 7 As shown, the number of batteries 3, solar panels 2, outdoor units 1, and electric heating devices are all multiple in a one-to-one correspondence. Therefore, after obtaining the chassis temperature of outdoor unit 1, the control method further includes:

[0111] If the chassis temperature of one of the outdoor units 1 is determined to be lower than the first set temperature, and the power of the battery 3 corresponding to that outdoor unit 1 is less than or equal to the second set discharge power, then the battery 3 corresponding to the outdoor unit 1 adjacent to that outdoor unit 1 is controlled to supply power to the electric heating device of that outdoor unit 1, so that the electric heating device heats the chassis of that outdoor unit 1.

[0112] In this way, when the battery 3 corresponding to one of the electric heating devices is low on power, in order to ensure that the electric heating device can properly heat and defrost the chassis of the outdoor unit 1, the system can take emergency measures, that is, control the battery 3 on the adjacent outdoor unit 1 to supply power to the electric heating device, so as to ensure the normal heating and defrosting process of the electric heating device.

[0113] According to some embodiments of the present invention, after the step of controlling the electric heating device to turn on and supplying it with power through the storage battery 3, the control method of the air conditioning system further includes:

[0114] If the chassis temperature of outdoor unit 1 is determined to be higher than the second set temperature, control the battery 3 to disconnect the power supply to the electric heating device.

[0115] It is understandable that when the chassis temperature of outdoor unit 1 is heated to a temperature higher than the second set temperature, it proves that the chassis of outdoor unit 1 has been completely defrosted. At this time, in order to avoid wasting the power of battery 3 and affecting the normal heating function of the air conditioner, the system will automatically disconnect the power supply of battery 3 to the electric heating device, so as to facilitate the continued execution of the normal heating process.

[0116] It should be explained that the first set temperature, the second set temperature, the first set discharge capacity, and the second set discharge capacity mentioned above are all preset values. These preset values ​​can be obtained from the system default settings or from the user settings. This invention does not impose any special limitations on the source of the above preset values ​​or their specific values.

[0117] A specific embodiment of the air conditioning system and control method of the present invention is described below with reference to the accompanying drawings.

[0118] like Figures 1 to 10 As shown, in the air conditioning system, the first bracket 51 is a triangular frame bracket. The bottom of the first bracket 51 is fixed to the top cover of the outdoor unit 1 by six screws. The cylinder part of the drive cylinder 52 is hinged to the first bracket 51. The drive part of the drive cylinder 52 is rotatably connected to the second bracket 53. The upper part of the second bracket 53 forms a cylindrical first sleeve part. The third bracket 55 forms a ring-shaped second sleeve part that matches the shape of the first sleeve part. The second sleeve part of the third bracket 55 is rotatably disposed on the outside of the first sleeve part of the second bracket 53 through the first bearing 58. The third bracket 55 is also provided with a drive motor 54. The drive motor 54 is connected to a worm gear 56. The worm gear 56 drives the third bracket 55 to rotate around the turbine 57 under the support of the second bearing 59, and synchronously drives the third bracket 55 to rotate around the second bracket 53.

[0119] Solar panel 2 is fixed on the third bracket 55. At this time, solar panel 2 can adjust its altitude angle under the action of the drive cylinder 52, and its azimuth angle under the action of the drive motor 54. A photoresistor detects the light intensity (whether it is cloudy). When a certain intensity is reached, the timing and positioning device is activated. The electronic control device 4 receives the solar altitude angle information, sends an electrical signal, and controls the hydraulic pump in the hydraulic system to start. After the system oil pressure reaches the standard, the electromagnetic reversing valve connects the hydraulic oil circuit, achieving precise control of the hydraulic cylinder stroke. When the solar altitude angle is high, the electronic control device 4 sends a signal to shorten the hydraulic cylinder stroke. The barrel end of the drive cylinder 52 is fixed to the first bracket 51 with no degree of freedom of travel. The drive rod of the drive cylinder 52 is connected to the second bracket 53, pulling the second bracket 53 to rotate counterclockwise around the pivot point. The second bracket 53 is connected to the third bracket 55 through the first bearing 58. When the second bracket 53 rotates counterclockwise, it causes the third bracket 55 to tilt forward, reducing the altitude angle of the solar panel 2 and achieving the effect of always being perpendicular to the sunlight. Conversely, the elevation angle of solar panel 2 increases.

[0120] Based on the specific structure of the air conditioning system described above, the specific control process of the air conditioning system includes a first-stage charging process and a second-stage discharging process. The specific control processes for the two stages are as follows:

[0121] The first stage of the charging process: A photoresistor detects the intensity of sunlight (whether it is cloudy). When the sunlight reaches a certain intensity, the timing and positioning device is activated, transmitting the latitude and longitude of the solar panel 2, along with the time information, to the electronic control device 4 in real time. The electronic control device 4 calculates the solar altitude and azimuth angles in real time and controls the drive motor 54 and the drive cylinder 52 to ensure that the solar charging panel is always in the optimal charging state perpendicular to the sunlight, thus charging the power source. When the power source is fully charged, the electronic control device 4 activates the interference charging protection to cut off the power.

[0122] The second stage of the discharge process: When outdoor unit 1 starts up cold, the electronic control device 4 detects that the ambient temperature of the chassis is below 0°C through the ambient temperature sensor installed on the chassis. It then turns on the power of the battery 3 to heat the electric heating device installed on the chassis until the ambient temperature of the chassis is above 10°C and then cuts off the power. At the same time, when multiple units are installed in a row, if the battery 3 of the Nth outdoor unit 1 has too low a charge, it can "borrow" power from the battery 3 of the adjacent N+1th or N-1th outdoor unit 1 to melt the ice accumulated on the chassis, thus realizing intelligent ice control on the chassis.

[0123] Furthermore, when this invention is applied to multi-split air conditioners, there are two power supply options, as follows:

[0124] like Figure 7As shown, the first method involves each outdoor unit 1 being equipped with an individual solar panel 2 and a battery 3. Each solar panel 2 charges its own battery 3. When the battery 3 of the Nth outdoor unit 1 is fully charged, the electronic control device 4 detects whether the battery 3 of the N+1 or N-1th connected outdoor unit 1 has a charge level below 70%. If the battery 3 of the adjacent N+1 or N-1th outdoor unit 1 has a charge level below 70%, the solar panel 2 of the Nth outdoor unit 1 charges the battery 3 of the adjacent N+1 or N-1th outdoor unit 1 until the battery 3 of the N+1 or N-1th outdoor unit 1 is fully charged, triggering the interference charging protection and cutting off the power. When the battery 3 powers the electric heating device, if the battery 3's charge level is below 100%, the solar panel 2 continues to charge the battery 3. This charging and discharging cycle of the battery 3 is repeated, achieving closed-loop intelligent refrigeration for each outdoor unit 1.

[0125] like Figure 8 As shown, the second method involves all multi-split air conditioners being equipped with a single main battery 3. Each outdoor unit 1 of the multi-split system is individually equipped with a smart charging device (including a solar panel 2 and a control linkage device). These smart charging devices can simultaneously charge the main battery 3 until it is fully charged, triggering overcharge protection and cutting off power. When the chassis of the first or (and) the Nth outdoor unit 1 freezes, the main battery 3 powers the electric heating device of the first or (and) the Nth outdoor unit 1, allowing the first or (and) the Nth outdoor unit 1 to defrost independently. At this time, the main battery 3's charge is below 100%, and the smart charging devices of each outdoor unit 1 simultaneously charge the main battery 3. This charging and discharging cycle of the main battery 3 is repeated, achieving closed-loop intelligent icing for each outdoor unit 1.

[0126] The electronic control device 4 receives real-time feedback information from the timing and positioning device, controlling the drive motor 54 and drive cylinder 52 to operate independently, ensuring that the solar panel 2 is always perpendicular to the sunlight and that charging efficiency remains optimal. The solar panel 2 charges the battery 3, and the power is cut off by interference protection once fully charged. When the outdoor unit 1 starts up cold, the electronic control device 4 detects that the ambient temperature of the chassis is below 0°C using an ambient temperature sensor installed on the chassis. It then turns on the battery 3 to power the electric heating device installed on the chassis, which melts the accumulated ice. The power is cut off again when the ambient temperature of the chassis rises above 10°C.

The electronic control device 4 of the air conditioning system described below can be referred to in correspondence with the control method of the air conditioning system described above.

[0131] The second control module 130 is used to control the operation of the control linkage device according to the solar position information when charging, so that the solar panel 2 is perpendicular to the current solar direction.
