Description

Technical Field

[0001] The present invention relates to the field of electrical equipment technology, and in particular to an air-conditioning system, a control method of the air-conditioning system and an electric control device thereof. Background Art

[0002] In the related art, the outdoor temperature in most areas is lower than 0° in winter, and the outdoor unit of the air conditioner is operated in an ambient temperature state below 0° for a long time. In rainy and snowy weather with an ambient temperature below 0°, the chassis and heat exchanger surface of the outdoor unit of the air conditioner are very easy to freeze, affecting the heat exchange efficiency, and in serious cases, it is easy to cause quality or safety hazards. Among them, the defrosting and deicing measures for the condenser are: when the outdoor unit cold machine is started, the compressor runs, and the ambient temperature is detected to be lower than 0°, the four-way valve is reversed, and the high-temperature and low-pressure refrigerant flows through the heat exchanger, the heat exchanger dissipates heat, and the outdoor unit fan is reversed at the same time to defrost and de-ice the heat exchanger. After the frost melts, a small part evaporates, and most of it flows to the chassis in the form of liquid water. Since the ambient temperature is lower than 0°, most of the water will freeze on the chassis. The ice layer will accumulate higher and higher after blocking the leakage hole of the chassis. If it is not de-iced in time, the ice layer will interfere with the running trajectory of the fan and break the fan. The fan fragments will burst out of the outdoor unit from the outdoor unit air cavity, which is easy to cause safety hazards.

[0003] At present, electric heating devices are commonly used to melt ice on the chassis of outdoor units. The power source of electric heating devices is generally industrial electricity and household electricity, which consumes a lot of electricity and is not energy-saving. A small number of them use solar panels for charging. Among them, solar panels are generally fixed and cannot always be perpendicular to the sunlight, so the charging efficiency is slow and the practicality is poor. Summary of the invention

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 8 As shown, the air conditioning system according to the first embodiment of the present invention includes an indoor unit (not shown in the figure), at least one outdoor unit 1, a solar panel 2, a battery 3 and an electronic control device 4.

[0024] An electric heating device (not shown in the figure) for melting ice in the outdoor unit 1 is provided in the outdoor unit 1 . For example, the electric heating device is installed on the chassis of the outdoor unit 1 .

[0025] The solar panel 2 is electrically connected to the battery 3 to charge it, and the battery 3 is electrically connected to the electric heating device to power it. The solar panel 2 is arranged on the outside of the outdoor unit 1 through a control linkage device to achieve adjustable azimuth and altitude angles.

[0026] The electronic control device 4 is connected to the control linkage device signal, and 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 altitude angle of the solar panel 2.

[0027] The specific working process of the air conditioning system according to the embodiment of the present invention is as follows: for the solar panel 2 and the battery 3 of the system, they have two working stages, namely, a charging stage and a discharging stage.

[0028] During the charging stage, 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 according to the position information of the sun, so that the control linkage device is actuated to drive the solar panel 2 to actuate, thereby realizing the adjustment of the azimuth and altitude angles of the solar panel 2. In this way, by adjusting the azimuth and altitude angles of the solar panel 2, the solar panel 2 can always face the direction of sunlight, so that the solar panel 2 can always receive good lighting conditions during the charging stage, thereby ensuring the solar charging efficiency. Furthermore, during the adjustment process of the solar panel 2, with the help of the position information of the sun, the solar panel 2 can be adjusted to a position that is always perpendicular to the direction of sunlight, thereby further improving the solar charging efficiency, so as to achieve maximum charging efficiency for charging the battery 3.

[0029] During the discharge stage, when the air-conditioning system is started in heating mode, ice may form on the bottom chassis of the outdoor unit 1. Therefore, after the outdoor unit 1 is started, the electronic control device 4 obtains the chassis temperature of the outdoor unit 1 through the temperature sensor installed on the chassis. When the electronic control device 4 detects that the chassis temperature of the outdoor unit 1 is lower than the set entry temperature, it proves that there is a risk of ice formation or ice has already formed on the chassis of the outdoor unit 1. Therefore, in order to avoid ice formation on the chassis of the outdoor unit 1 or directly eliminate ice formation on the chassis of the outdoor unit 1, the electronic control device 4 will control the battery 3 to discharge the electric heating device and turn on the electric heating device at the same time, so that the electric heating device heats the chassis of the outdoor unit 1, thereby eliminating the frost condensed on the chassis of the outdoor unit 1. During the heating process, if the electronic control device 4 further detects that the chassis temperature of the outdoor unit 1 is 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 defrosting process of the outdoor unit 1.

[0030] In the related art, the outdoor temperature in most areas is lower than 0° in winter, and the outdoor unit of the air conditioner is operated in an ambient temperature state below 0° for a long time. In rainy and snowy weather with an ambient temperature below 0°, the chassis and heat exchanger surface of the outdoor unit of the air conditioner are very easy to freeze, affecting the heat exchange efficiency, and in serious cases, it is easy to cause quality or safety hazards. Among them, the defrosting and deicing measures for the condenser are: when the outdoor unit cold machine is started, the compressor runs, and the ambient temperature is detected to be lower than 0°, the four-way valve is reversed, and the high-temperature and low-pressure refrigerant flows through the heat exchanger, the heat exchanger dissipates heat, and the outdoor unit fan is reversed at the same time to defrost and de-ice the heat exchanger. After the frost melts, a small part evaporates, and most of it flows to the chassis in the form of liquid water. Since the ambient temperature is lower than 0°, most of the water will freeze on the chassis. The ice layer will accumulate higher and higher after blocking the leakage hole of the chassis. If it is not de-iced in time, the ice layer will interfere with the running trajectory of the fan and break the fan. The fan fragments will burst out of the outdoor unit from the outdoor unit air cavity, which is easy to cause safety hazards.

[0031] At present, electric heating devices are commonly used to melt ice on the chassis of outdoor units. The power source of electric heating devices is generally industrial electricity and household electricity, which consumes a lot of electricity and is not energy-saving. A small number of them use solar panels for charging. Among them, solar panels are generally fixed and cannot always be perpendicular to the sunlight, so the charging efficiency is slow and the practicality is poor.

[0032] Therefore, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention proposes an air-conditioning system, which adds a solar panel 2 on the outside of the outdoor unit 1, uses the solar panel 2 to charge the battery 3, and uses the battery 3 to power the electric heating device, and controls the electric heating device to heat the chassis of the outdoor unit 1 to realize the ice-melting process of the outdoor unit 1. There is no need to input other industrial electricity and household electricity, but solar energy is converted into electrical energy to power the electric heating device. The original electricity usage method is replaced by green and environmentally friendly solar energy electricity, which realizes the effective utilization of clean energy and reduces the energy consumption of the entire air-conditioning system.

[0033] In addition, during the process of the solar panel 2 charging the battery 3, the electronic control device 4 can adjust the position 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 a high or even maximum charging efficiency. It is highly practical and can be applied to various weather conditions and terrain conditions.

[0034] For the control linkage device of the present invention, it is necessary to realize the adjustment of the azimuth and altitude angle of the solar panel 2. Therefore, two driving members are arranged in the control linkage device, and one of the driving members is used to realize the rotation action to adjust the azimuth angle of the solar panel 2, and the other driving member is used to realize the adjustment of the up and down height and its inclination angle to adjust the altitude angle of the solar panel 2. It can be understood that the two driving members can be both linear driving members (such as oil cylinders or air cylinders, etc.), both rotary driving members (such as motors, etc.), or one of them is a linear driving member and the other is a rotary driving member. At this time, under different combinations of driving member types, the above two driving members can realize the above two aspects of adjustment through different transmission components. For example, the transmission component includes but is not limited to a worm gear 56 structure, a connecting rod structure, a hinge structure, a screw nut structure, etc. Therefore, the present invention does not specifically limit the types of the two driving members, and does not specifically limit the structure of the transmission component connected to the driving member, as long as the above linkage control device can realize the azimuth adjustment and altitude adjustment of the solar panel 2.

[0035] A specific structure of the control linkage device in the air conditioning system of the present invention is introduced below.

[0036] like Figures 3 to 6 As shown, according to a specific embodiment of the present invention, the control linkage device includes a first bracket 51 , a driving cylinder 52 , a second bracket 53 , a driving motor 54 and a third bracket 55 .

[0037] The first bracket 51 is fixed to the housing of the outdoor unit 1 , the cylinder portion of the driving cylinder 52 is rotatably connected to the first bracket 51 , and the driving portion of the driving cylinder 52 is rotatably connected to the second bracket 53 .

[0038] The third bracket 55 is sleeved on the outside of the second bracket 53 . The driving motor 54 is fixed to the third bracket 55 . The driving motor 54 drives the third bracket 55 to rotate relative to the second bracket 53 via the worm gear 56 structure. The solar panel 2 is fixed to the third bracket 55 .

[0039] In this way, when the drive motor 54 is started, the drive motor 54 can drive the third bracket 55 to rotate in the horizontal direction relative to the second bracket 53 through the worm gear 56 structure, that is, control the solar panel 2 to rotate in the horizontal direction to face different orientations. It can be understood that the purpose of the above-mentioned process of controlling the action of the drive motor 54 is to achieve the adjustment of the azimuth angle of the solar panel 2, that is, to achieve the solar panel 2 facing different orientations (such as different orientations such as east, south, west, etc.).

[0040] When the driving cylinder 52 is started, the driving part of the driving cylinder 52 pushes the second bracket 53 to move forward and upward or backward and downward in an arc track. At this time, the second bracket 53 drives the third bracket 55 to move and then drives the solar panel 2 to move forward and upward or backward and downward, so that the height of the solar panel 2 changes, and the angle between the solar panel 2 and the horizontal plane also changes, that is, the control and adjustment of the height angle of the solar panel 2 is realized. It can be understood that the purpose of the above-mentioned process of controlling the action of the driving cylinder 52 is to achieve the adjustment of the height angle of the solar panel 2.

[0041] For example, the first bracket 51 is a triangular frame-shaped 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 driving cylinder 52 is hinged to the first bracket 51, and the driving part of the driving cylinder 52 is rotatably connected to the second bracket 53. The upper part of the second bracket 53 forms a cylindrical first sleeve part, and the third bracket 55 forms a circular ring-shaped second sleeve part matching the shape of the first sleeve part. The second sleeve part of the third bracket 55 is rotatably arranged on the outer side of the first sleeve part of the second bracket 53 through the first bearing 58. The third bracket 55 is also provided with a driving motor 54, and the driving motor 54 is connected to the worm 56. The worm 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.

[0042] The solar panel 2 is fixed on the third bracket 55 . At this time, the solar panel 2 can adjust the altitude angle under the action of the driving cylinder 52 , and can adjust the azimuth angle under the action of the driving motor 54 .

[0043] According to some embodiments of the present invention, the electronic control device 4 is respectively connected to the drive cylinder 52 and the drive motor 54 by signals. The electronic control device 4 is used to control the action of 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 action of the drive cylinder 52 to adjust the altitude angle of the solar panel 2 according to the altitude angle information of the sun.

[0044] In this way, the electronic control device 4 continuously adjusts the azimuth and altitude 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 sun's illumination azimuth angle, and the altitude angle of the solar panel 2 continuously approaches the sun's illumination altitude angle, ultimately achieving the technical effect that the solar panel 2 always remains perpendicular to the sun's illumination direction.

[0045] 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 arranged on the outdoor unit 1 in a one-to-one correspondence through a control linkage device.

[0046] In this way, when there are multiple outdoor units 1, the multiple outdoor units 1 can all utilize the solar panels 2 arranged thereon to utilize solar energy, thereby improving the efficiency of the entire system in absorbing solar energy, thereby storing more electrical energy for the system.

[0047] According to some embodiments of the present invention, in the entire air conditioning system, the number of batteries 3 may be one, two or more, that is, multiple solar panels 2 may simultaneously power one battery 3, or multiple solar panels 2 may also independently power multiple batteries 3. The present invention is not particularly limited herein.

[0048] For example, Figure 7 As shown, there are multiple batteries 3 , and the multiple batteries 3 correspond one-to-one to the multiple solar panels 2 and the multiple outdoor units 1 .

[0049] The electric control device 4 is used to control the storage battery 3 corresponding to another indoor unit adjacent thereto to charge the storage battery 3 when it is detected that the power level of the storage battery 3 corresponding to one of the indoor units is lower than the set power level.

[0050] That is, in the present embodiment, the plurality of solar panels 2 respectively and independently supply power to the plurality of batteries 3, and in addition to being able to charge the batteries 3 through the solar panels 2, the plurality of batteries 3 can also be connected to each other to charge each other. Specifically, when one of the batteries 3 is low on power, another or two batteries 3 adjacent to the battery 3 can charge the battery 3, thereby ensuring the health of the power level of each battery 3 to avoid affecting the subsequent defrosting and defrosting process.

[0051] Furthermore, when there are multiple batteries 3, the multiple batteries 3 and the electric heating devices installed on the multiple outdoor units 1 also correspond one to one, that is, each electric heating device corresponds to a battery 3 to power it, so that the defrosting processes between the multiple electric heating devices are independent of each other, avoiding the impact of insufficient power of one of the batteries 3 on the power supply of other batteries 3 to other electric heating devices, thereby ensuring the stability of the defrosting system.

[0052] For example, Figure 8 As shown, the number of storage batteries 3 is one, and all solar panels 2 are electrically connected to the storage batteries 3. The electronic control device 4 is used to control the solar panels 2 to charge the storage batteries 3 when it is detected that the total power of the storage batteries 3 is lower than the set power.

[0053] That is, in this embodiment, multiple solar panels 2 charge the same battery 3 at the same time, and when the battery 3 is low on power, the charging process is restarted. In this way, by charging one battery 3 with multiple solar panels 2 at the same time, the charging efficiency of the battery 3 can be greatly improved. 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 in the system is also simpler and more stable, thereby ensuring the stability of the charging and discharging process of the battery 3 in the system.

[0054] Furthermore, when there is only one battery 3 , the battery 3 is electrically connected to the electric heating devices of all indoor units at the same time, that is, the battery 3 supplies power to all electric heating devices at the same time to ensure smooth defrosting of all outdoor units 1 .

[0055] The control method and control device of the air-conditioning system proposed in the present invention are described below with reference to the accompanying drawings. Among them, before the embodiment of the present invention is described in detail, the entire application scenario is first described. The control method, control device, electronic device and computer-readable storage medium of the air-conditioning in the embodiment of the present invention can be applied to the air-conditioning locally, and can also be applied to the cloud platform in the Internet field, or other types of cloud platforms in the Internet field, or can also be applied to third-party devices. Among them, the third-party device may include many different types such as mobile phones, tablet computers, notebooks, car computers and other smart terminals.

[0056] The following is only an example of a control method applicable to an air conditioner. It should be understood that the control method of the embodiment of the present invention can also be applied to a cloud platform and a third-party device. It should be noted that the control method is implemented based on the structure of the air conditioning system described above.

[0057] like Fig. 9 As shown, a control method for an air conditioning system according to a second aspect of an embodiment of the present invention includes: Step S1, obtaining the power of the battery 3; Step S2, when it is determined that the power of the storage battery 3 is lower than the set charging power, the solar panel 2 is controlled to enter the charging state, and the current sun's illumination position information relative to the solar panel 2 is obtained; Step S3, in the charging state, according to the sunlight position information, the linkage device is controlled to operate so that the solar panel 2 is perpendicular to the current sunlight direction.

[0058] According to the control method of the air-conditioning system of the embodiment of the present invention, by controlling the relevant linkage structure and the hydraulic system, the solar panel 2 is always perpendicular to the sunlight, and the battery is charged with the best efficiency to store the electrical energy; further, the electric heating device of the air-conditioning outdoor unit 1 is powered by the battery discharge to realize intelligent icing.

[0059] During the charging and discharging process of the above-mentioned storage battery 3, energy conversion is initially from solar energy to electrical energy, and then from electrical energy to thermal energy, so as to realize chassis ice melting, which greatly reduces energy consumption.

[0060] According to some embodiments of the present invention, the illumination position information includes the illumination altitude angle and illumination azimuth angle of the sun. Then, in the charging state, the steps of controlling the action of the linkage device according to the illumination position information of the sun specifically include: In the charging state, according to the solar illumination altitude angle, the driving cylinder 52 is controlled to move to adjust the altitude angle of the solar panel 2 until the altitude angle of the solar panel 2 is equal to the illumination altitude angle; In the charging state, the driving motor 54 is controlled to operate according to the sunlight azimuth to adjust the azimuth of the solar panel 2 until the azimuth of the solar panel 2 is equal to the sunlight azimuth.

[0061] In this way, by controlling the actions of the driving cylinder 52 and the driving motor 54 respectively, the azimuth angle of the solar panel 2 can be adjusted to an angle equal to the azimuth angle of the sun's illumination, and the altitude angle of the solar panel 2 can be adjusted to an angle equal to the altitude azimuth angle of the sun, so that the solar panel 2 remains perpendicular to the direction of the sun's illumination, allowing the battery 3 to always be charged with maximum charging efficiency.

[0062] According to some embodiments of the present invention, Figure 7 As shown, the number of the battery 3, the solar panel 2 and the outdoor unit 1 are all one-to-one corresponding to each other, and the control method further includes: Obtain the power of the battery 3 corresponding to each indoor unit; When it is determined that the power level of the storage battery 3 corresponding to one of the indoor units is lower than the minimum set power level, the storage battery 3 corresponding to another adjacent indoor unit is controlled to be charged.

[0063] In this way, when one of the batteries 3 is low on power, another or two other batteries 3 adjacent to the battery 3 can charge the battery 3, thereby ensuring the health of the power of each battery 3 to avoid affecting the subsequent defrosting and defrosting process.

[0064] According to some embodiments of the present invention, the control method of the air conditioning system further includes: Get the chassis temperature of outdoor unit 1; It is determined that the chassis temperature is lower than the first set temperature and the power of the battery 3 is greater than the first set discharge power, and the electric heating device is controlled to be turned on and powered by the battery 3 to heat the chassis of the outdoor unit 1.

[0065] 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.

[0066] According to some embodiments of the present invention, Figure 7 As shown, the number of the battery 3, the solar panel 2, the outdoor unit 1 and the electric heating device are all one-to-one corresponding to each other. After the step of obtaining the chassis temperature of the outdoor unit 1, the control method further includes: When it is determined that the chassis temperature of one of the outdoor units 1 is lower than the first set temperature, and the power level of the battery 3 corresponding to the outdoor unit 1 is less than or equal to the second set discharge power, the battery 3 corresponding to the outdoor unit 1 adjacent to the outdoor unit 1 is controlled to supply power to the electric heating device of the outdoor unit 1, so that the electric heating device heats the chassis of the outdoor unit 1.

[0067] 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 normally heat and defrost the chassis of the outdoor unit 1, the system can take emergency operation, that is, control the battery 3 on the adjacent outdoor unit 1 to power the electric heating device to ensure the normal heating and defrosting process of the electric heating device.

[0068] According to some embodiments of the present invention, after the step of controlling the electric heating device to be turned on and supplying power to the electric heating device through the storage battery 3, the control method of the air conditioning system further includes: It is determined that the chassis temperature of the outdoor unit 1 is higher than the second set temperature, and the storage battery 3 is controlled to cut off the power supply to the electric heating device.

[0069] It can be understood that when the chassis temperature of the outdoor unit 1 is heated to a temperature higher than the second set temperature, it proves that the chassis of the outdoor unit 1 has been completely defrosted. At this time, in order to avoid wasting battery 3 power and affecting the normal heating function of the air conditioner, the system will automatically disconnect the battery 3 from supplying power to the electric heating device, thereby facilitating the subsequent continuation of the normal heating process.

[0070] It should be explained that the above-mentioned first set temperature, second set temperature, first set discharge power and second set discharge power are all pre-set set values, and the above-mentioned set values ​​can be obtained from the system default settings, or can also be obtained from user settings. The present invention does not specifically limit the acquisition source of the above-mentioned set values ​​and the specific numerical values.

[0071] A specific embodiment of the air conditioning system and control method thereof of the present invention is described below with reference to the accompanying drawings.

[0072] like Figures 1 to 10As shown, in the air-conditioning system, the first bracket 51 is a triangular frame-shaped 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 driving cylinder 52 is hinged to the first bracket 51, and the driving part of the driving cylinder 52 is rotatably connected to the second bracket 53. The upper part of the second bracket 53 forms a cylindrical first sleeve part, and the third bracket 55 forms a circular ring-shaped second sleeve part matching the shape of the first sleeve part. The second sleeve part of the third bracket 55 is rotatably arranged on the outer side of the first sleeve part of the second bracket 53 through a first bearing 58. A driving motor 54 is also provided on the third bracket 55, and the driving motor 54 is connected to a worm 56. The worm 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.

[0073] The solar panel 2 is fixed on the third bracket 55. At this time, the solar panel 2 can adjust the altitude angle under the action of the driving cylinder 52, and adjust the azimuth angle under the action of the driving motor 54. The photoresistor detects the light intensity (whether it is cloudy). When it reaches a certain intensity, the timing and positioning device starts, the electronic control device 4 receives the solar altitude information, sends an electrical signal, controls the hydraulic oil pump in the hydraulic system to start, and after the system oil pressure reaches the standard, the electromagnetic reversing valve connects the hydraulic oil circuit to achieve precise control of the hydraulic cylinder stroke. When the solar altitude is high, the electronic control device 4 sends a signal to control the hydraulic cylinder stroke to shorten, the barrel end of the driving cylinder 52 is fixed with the first bracket 51 and has no freedom of travel, the driving rod of the driving cylinder 52 is connected to the second bracket 53, and the second bracket 53 is pulled to rotate counterclockwise around the turning 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 drives the third bracket 55 to tilt forward, and the altitude angle of the solar panel 2 is reduced, so as to achieve the effect of always being perpendicular to the sunlight. On the contrary, the altitude angle of the solar panel 2 increases.

[0074] Based on the specific structure of the above air-conditioning system, 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 of the above two stages are as follows: The first stage of charging process: the photoresistor detects the intensity of sunlight (whether it is cloudy or not). When the light reaches a certain intensity, the timing and positioning device starts, and transmits the geographical location information such as the latitude and longitude of the solar panel 2 and the time information in real time to the electronic control device 4. The electronic control device 4 calculates the altitude angle and azimuth angle of the sun in real time, and controls the action of the drive motor 54 and the drive cylinder 52, so that the solar charging panel is always in the best charging state perpendicular to the sunlight to charge the power supply. When the power supply is fully charged, the electronic control device 4 starts the overcharge protection and cuts off the power.

[0075] The second stage of discharge process: when the outdoor unit 1 is started cold, the electronic control device 4 detects that the chassis ambient temperature is lower than 0° through the ambient temperature sensor installed on the chassis, and 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 higher than 10° and then cuts off the power. At the same time, if multiple units are installed in a row, and the battery 3 of the Nth outdoor unit 1 is too low, it can "borrow power" from the battery 3 of the nearby N+1th or N-1th outdoor unit 1 to melt the ice accumulated on the chassis, thereby realizing intelligent chassis ice.

[0076] Furthermore, when the present invention is applied to a multi-split air conditioner, there are two power supply forms, which are as follows: like Figure 7 As shown, the first type is that each outdoor unit 1 is equipped with a solar panel 2 and a battery 3, and each solar panel 2 charges its own battery 3. When the battery 3 of the Nth outdoor unit 1 is fully charged, the electric control device 4 detects whether the battery 3 of the other connected N+1 or N-1th outdoor unit 1 is less than 70%. If the battery 3 of the adjacent N+1 or N-1th outdoor unit 1 is less than 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 and the overcharge protection is triggered to cut off the power. When the battery 3 is powered on to the electric heating device, the battery 3 is less than 100% at this time, and the solar panel 2 continues to charge the battery 3. The charging and discharging of the battery 3 is repeated to realize the closed-loop intelligent refrigeration of each outdoor unit 1.

[0077] like Figure 8 As shown, the second type is that all multi-split units are uniformly equipped with the same total battery 3, and each multi-split outdoor unit 1 is separately equipped with an intelligent charging device (including a solar panel 2 and a control linkage device). These intelligent charging devices can charge the total battery 3 at the same time until it is fully charged and triggers the overcharge protection to cut off the power. When the chassis of the first or (and) the Nth outdoor unit 1 is frozen, the total battery 3 energizes the electric heating device of the first or (and) the Nth outdoor unit 1, and the first or (and) the Nth outdoor unit 1 can melt the ice separately. At this time, the power of the total battery 3 is less than 100%, and the intelligent charging device of each multi-split outdoor unit 1 charges the total battery 3 at the same time. The total battery 3 is charged and discharged repeatedly to achieve closed-loop intelligent freezing of each outdoor unit 1.

[0078] The electronic control device 4 receives the information fed back by the timing and positioning device in real time, controls the driving motor 54 and the driving cylinder 52 to act respectively, so that the solar panel 2 is always perpendicular to the sunlight and the charging efficiency is always kept at the best. The solar panel 2 charges the battery 3, and the power is cut off for overfill protection after it is fully charged. When the outdoor unit 1 is started cold, the electronic control device 4 detects that the ambient temperature of the chassis is lower than 0° through the ambient temperature sensor installed on the chassis, turns on the power of the battery 3, and energizes the electric heating device installed on the chassis. The electric heating device generates heat to melt the accumulated ice, and the power is cut off when the ambient temperature at the chassis is higher than 10°.
