Description

Technical Field

[0002] Solar air conditioning is an air conditioning system that uses solar energy as a power source or part of the power source. It converts the energy of sunlight into electrical energy or thermal energy to drive the air conditioning system to achieve the purpose of cooling or heating. It combines renewable energy technology and high-efficiency energy-saving technology to reduce dependence on traditional fossil fuels, reduce energy consumption and environmental impact. There are generally two main types of solar air conditioners: solar photovoltaic air conditioners and solar thermal-driven air conditioners. Solar photovoltaic air conditioners use solar photovoltaic panels to convert sunlight directly into electrical energy, which can then be used to run traditional electric air conditioning equipment. When the electricity generated exceeds the air conditioning requirement, the excess electricity can be stored for later use or fed back to the power grid.

[0003] Solar photovoltaic air conditioners need to use photovoltaic panels to collect solar energy. The air conditioners mainly include indoor units and outdoor units. Since the outdoor units of air conditioners are exposed to the outdoors for a long time, the photovoltaic panels are installed on the outdoor units. Although the existing solar photovoltaic air conditioners can meet the basic use needs, the disadvantages are also very obvious, which are mainly manifested in: the photovoltaic panels of photovoltaic air conditioners in the prior art are installed through simple brackets, and are exposed to the outside regardless of whether there is sunlight or other harsh environments, resulting in a short service life and high maintenance costs; and the photovoltaic panels cannot adaptively adjust their tilt angle according to the angle of sunlight, resulting in low utilization of solar energy; and the area of ​​the air conditioner outer case is limited, which leads to the limitation of the installation area of ​​the photovoltaic panels, and it is impossible to install more photovoltaic panels to improve the utilization of solar energy.

[0004] In addition, in the existing solar air-conditioning power supply system, the power generation of the solar panels is unstable because the solar air-conditioning is affected by the external environment. Users cannot accurately know the expected power generation of the solar panels and cannot intelligently switch the power supply mode of the air-conditioning, resulting in the solar air-conditioning being unable to meet the needs of users in certain environments.

[0019] Furthermore, the electrical equipment in the above photovoltaic air-conditioning power supply system are all located indoors.

[0020] Furthermore, the current output end of the crystalline silicon photovoltaic panel module is electrically connected to the input end of the combiner box through a wire, the output end of the combiner box is electrically connected to the current input end of the inverter, the current output end of the inverter is electrically connected to the current input end of the battery, the current output end of the battery is electrically connected to the current input end of the transformer, the current output end of the transformer is electrically connected to the photovoltaic power input end of the distribution cabinet, and the AC input end is electrically connected to the AC input end of the distribution cabinet.

[0021] Furthermore, the combiner box collects the current generated by multiple photovoltaic panels in the crystalline silicon photovoltaic panel module and transmits it to the inverter. The inverter converts the direct current generated by the crystalline silicon photovoltaic panel module into alternating current and stores it in the battery. The battery is equipped with a power monitoring module to monitor the battery's power, voltage, and current in real time, and provide the battery's power and output power to the power distribution control module. The transformer increases the voltage output by the battery to a voltage suitable for the normal operation of the electrical equipment.

[0022] Furthermore, the photovoltaic power input terminal and the mains power input terminal are electrically connected to the power distribution control module respectively, the power distribution control module is electrically connected to the power monitoring module, and the power monitoring module is electrically connected to output terminals No. 1 to No. 10 of the power distribution cabinet.

[0023] Furthermore, output terminal No. 1 is electrically connected to the sunlight sensor, output terminal No. 2 is electrically connected to the photovoltaic control module, output terminal No. 3 is electrically connected to the power-off electromagnetic lock, output terminal No. 4 is electrically connected to rotary motor 1, output terminal No. 5 is electrically connected to rotary motor 2, output terminal No. 6 is electrically connected to electric push rod 1, output terminal No. 7 is electrically connected to electric push rod 2, output terminal No. 8 is electrically connected to the indoor motor of the air conditioner, output terminal No. 9 is electrically connected to the outdoor motor of the air conditioner, and output terminal No. 10 is provided with multiple two-hole and three-hole interfaces, which can supply power to some household appliances, such as: desk lamps, monitors, electric fans, water purifiers, washing machines, refrigerators, air purifiers, etc.

[0024] Furthermore, the distribution cabinet is provided with a display screen and indicator lights. The display screen displays the current battery power, photovoltaic charging power, output power of each output end, and power supply switching buttons of each output end. Users can manually select the power supply mode of each output end through the power supply switching button: photovoltaic power supply or AC power supply.

[0025] Furthermore, the power distribution control module can intelligently switch the power supply mode according to the actual power generation of the photovoltaic panel, the battery power and output power, the air conditioner operation status and user needs. When the photovoltaic air conditioner is installed and turned on for the first time, the power distribution control module reads the battery power and output power measured by the battery power monitoring module, and combines the operating status of each output terminal appliance to determine whether the battery output power meets the rated power of each output terminal electrical equipment. If it meets the requirements, the battery is used for power supply. If not, the mains is used for power supply.

[0026] Furthermore, when the air conditioner is turned on, the crystalline silicon photovoltaic panel module unfolds, receives sunlight to generate electricity, and stores the electricity in the battery through the junction box and inverter. The power distribution control module compares the working power of each output-end appliance monitored by the power monitoring module with the output power of the battery. If the output power of the battery is lower than the working power of all output-end appliances, the power distribution control module uses the mains to power all appliances.

[0027] Furthermore, as the power generation time of the crystalline silicon photovoltaic panel module increases, the amount of electricity stored in the battery increases, and the output power of the battery increases. The power distribution control module can use the photovoltaic electricity stored in the battery to power the electrical appliances at each output end. The power supply logic is: ① When it is detected that the battery power is below 20%, the AC power is used to power all the electrical appliances at the output end.

[0028] ② When it is detected that the battery power reaches more than 20%, and the battery output power meets the working power of any one of the solar sensor, photovoltaic control module, power-off electromagnetic lock, rotary motor 1, rotary motor 2, electric push rod 1, and electric push rod 2, the power distribution control module uses the photovoltaic power stored in the battery to power the output end appliance. As the crystalline silicon photovoltaic panel module continues to generate electricity, the battery output power gradually increases and will gradually meet the working power of the output end appliances 1 to 7. If it is met, the power distribution control module will switch the output end to photovoltaic power supply.

[0029] ③ When it is detected that the battery power reaches more than 60% and the battery output power meets the working power of the air conditioner indoor unit, the power distribution control module switches output terminal 8 to photovoltaic power supply.

[0030] ④ When it is detected that the battery power reaches more than 90% and the battery output power meets the working power of the air conditioner outdoor unit, the power distribution control module switches the No. 9 and No. 10 output terminals to photovoltaic power supply.

[0031] Furthermore, the present invention also provides a working mode - photovoltaic power generation mode. When this mode is activated, the air conditioner is not turned on and the crystalline silicon photovoltaic panel module will expand to receive sunlight to generate electricity. The photovoltaic control module obtains the direction and angle of sunlight according to the sunlight sensor, and adjusts the direction and inclination of photovoltaic panel two and the flip angle of photovoltaic panel three in real time to ensure the maximum power generation efficiency of the crystalline silicon photovoltaic panel module, thereby quickly charging the battery.

[0032] Furthermore, in the above mode, when the battery power is less than 30%, the power distribution control module switches output terminal 10 to mains power supply. When the battery power is ≥30%, the power distribution control module switches output terminal 10 to photovoltaic power supply. At this time, the battery is in a state of being charged through the crystalline silicon photovoltaic panel module while supplying power to household appliances through output terminal 10. When the battery power reaches 100%, the indicator light on the distribution cabinet lights up green at the same time, reminding the user to use the photovoltaic power in the battery through output terminal 10 of the distribution cabinet to power some appliances at home. Turn off the photovoltaic power generation mode, and the crystalline silicon photovoltaic panel module is folded and retracted.

[0033] Furthermore, the backboard on the back of the photovoltaic panel is a glass fiber board, a carbon fiber board, or a basalt fiber board, and the surface is sprayed with a sun-proof and heat-insulating coating. When the air conditioner is turned off and the photovoltaic panel is rotated and folded upward, the backboard can play a good heat-insulating role, especially in extreme weather such as hail, the fiberboard on the back can effectively resist the impact of hail and protect the photovoltaic panel.

[0034] The beneficial effects of the present invention are as follows: by providing a chassis frame group, a crystalline silicon photovoltaic panel module, a flip drive mechanism and an angle adjustment mechanism, a plurality of photovoltaic panels can be directly fixed or movably installed on the chassis frame group, and the chassis frame group design allows the installation of multiple photovoltaic panels in a limited space, thereby increasing the installation area of ​​the photovoltaic panels and improving the utilization effect of solar energy; and through the foldable design, the movable photovoltaic panels can be unfolded by controlling the flip drive mechanism when the air conditioner is running, thereby exposing each photovoltaic panel to receive sunlight, and through the cooperation of the electric push rod and the angle adjustment mechanism, the photovoltaic panels can automatically adjust the angle and position according to the angle of the sunlight to follow the sun's position, thereby ensuring that each photovoltaic panel can receive sunlight, capture more sunlight, and ensure the power generation efficiency of the photovoltaic panels; when the air conditioner is shut down, the photovoltaic panels can be flipped or moved back to overlap with the photovoltaic panels of the chassis frame group, thereby realizing the folding and protection functions, reducing the damage to the photovoltaic panels due to severe weather conditions, extending the service life of the photovoltaic panels, and reducing maintenance costs. At the same time, the present invention provides a power supply system, which can provide photovoltaic power supply, mains power supply, and photovoltaic and mains mixed power supply modes for air conditioners and other electrical equipment through a power supply control module, and can intelligently switch power supply modes according to the actual photovoltaic panel power generation, air conditioner operation and user needs, thereby greatly reducing the use of mains power by air conditioners and other electrical facilities, thereby achieving the purpose of energy saving and emission reduction.

When the air conditioner is running, the rotary motor 1 66 drives the active gear 67 to rotate forward, and the screw 61 is driven to rotate under the meshing force of the active gear 67 and the passive gear 62, and the screw 61 and the nut 63 are driven to move downward under the thread matching effect of the screw 61 and the nut 63, and the photovoltaic panel 2 32 is flipped downward around the rotating shaft 5. At the same time, the photovoltaic panel 2 32 is pulled by the flipping rope 68 to ensure that the photovoltaic panel 2 32 flips smoothly and controls the flipping angle of the photovoltaic panel 2 32, so that both the photovoltaic panel 1 31 and the photovoltaic panel 2 32 are exposed; at the same time, the electric push rod 2 8 The photovoltaic panel four 34 is extended to be moved upward from the rear of the chassis frame group 2 to be exposed; and the rotating motor two 74 drives the gear 75 to rotate, and under the meshing force of the driving gear 75 and the ring gear 72, the turntable 71 and the photovoltaic panel three 33 are driven to rotate slowly, and the horizontal angle of the photovoltaic panel three 33 is adjusted. At the same time, the electric push rod one 77 is extended to adjust the inclination angle of the photovoltaic panel three 33 so that the photovoltaic panel three 33 corresponds to the position of the sun. At this time, all the photovoltaic panels are exposed to the outside world to collect sunlight, thereby realizing efficient use of solar energy.

[0048] When the air conditioner is stopped, the rotary motor 1 66 drives the driving gear 67 to rotate in the opposite direction, driving the screw 61 to rotate, and then controlling the nut 63 to move upward, and pulling the photovoltaic panel 2 32 upward and retracting it by flipping the pull rope 68, so that the photovoltaic panel 2 32 and the photovoltaic panel 1 31 overlap, and at the same time, the electric push rod 2 8 contracts to drive the photovoltaic panel 4 34 to be retracted into the chassis frame group 2, thereby realizing the closure of the chassis frame group 2.

[0049] Embodiment 2: Based on Embodiment 1, Figure 1 and Figure 2As shown, a power-losing electromagnetic lock 10 is installed on the top of the upper frame beams on the left and right sides of the detachable frame 21 and the fixed frame 22, and a locking part matching the power-losing electromagnetic lock 10 is provided on the top of the movable end of the photovoltaic panel 2 32. When the air conditioner is stopped and the photovoltaic panel 2 32 is flipped and retracted, the power-losing electromagnetic lock 10 will start and lock the movable end of the photovoltaic panel 2 32 through the locking part, thereby limiting and fixing the top of the photovoltaic panel 2 32, further improving the stability of the photovoltaic panel 2 32 after retraction.

[0050] Embodiment 3: Based on Embodiment 1, Figure 2 As shown, a solar sensor 9 can be installed on the photovoltaic panel 1 31 and the photovoltaic panel 3 33. The solar sensor 9 can identify the direction and angle of sunlight, and then determine the inclination and horizontal rotation angle of the photovoltaic panel 2 32 and the photovoltaic panel 4 34, so that the photovoltaic panel 2 32 and the photovoltaic panel 3 33 can follow the sunlight, further improving the utilization effect of solar energy. The solar sensor 9 can identify the direction and angle of sunlight, and then determine the inclination and horizontal rotation angle of the photovoltaic panel.

[0051] A photovoltaic control module 11 is provided on the frame support plate 24 above the chassis fixed frame 22. The photovoltaic control module 11 obtains the direction and angle of sunlight according to the solar ray sensor 9, controls the rotation of the rotary motor 1 66, adjusts the direction of the photovoltaic panel 2 32, controls the extension and retraction of the electric push rod 1 77, adjusts the angle of the photovoltaic panel 2 32, and ensures a higher power generation efficiency of the photovoltaic panel 2 32.

[0052] Embodiment 4: This embodiment provides a photovoltaic air conditioner electrical connection method and a power supply method of the power supply system. like Figure 10-13 As shown, the current output end of the crystalline silicon photovoltaic panel module 3 is electrically connected to the input end of the junction box 12 through a wire, the output end of the junction box 12 is electrically connected to the current input end of the inverter 13, the current output end of the inverter 13 is electrically connected to the current input end of the battery 14, the current output end of the battery 14 is electrically connected to the current input end of the transformer 15, the current output end of the transformer 15 is electrically connected to the photovoltaic power input end of the distribution cabinet 16, and the AC power and the AC power input end of the distribution cabinet are electrically connected.

[0053] The junction box 12 and the inverter 13 are located inside the photovoltaic air conditioner exterior unit, and the battery 14 and the transformer 15 are located indoors. The junction box 12 brings together the currents generated by multiple photovoltaic panels in the crystalline silicon photovoltaic panel module 3 for centralized management and transmission. Since both household and commercial electricity are AC, the inverter 13 can convert the DC power generated by the crystalline silicon photovoltaic panel module 3 into AC. The battery 14 stores the electrical energy generated by the crystalline silicon photovoltaic panel module 3, and is internally provided with a power monitoring module to monitor the battery's charge, voltage, and current in real time, and provide the battery's real-time output power to the power distribution control module. The transformer 15 then increases the voltage output by the battery 14 to a voltage suitable for the normal operation of the electrical equipment. The electrical equipment in the above-mentioned photovoltaic air conditioner power supply system are all located indoors.

[0054] The connection method between the distribution cabinet 16 and each electrical component is as follows: output terminal No. 1 is electrically connected to the sunlight sensor 9, output terminal No. 2 is electrically connected to the photovoltaic control module 11, output terminal No. 3 is electrically connected to the power-off electromagnetic lock 10, output terminal No. 4 is electrically connected to the rotary motor 1 66, output terminal No. 5 is electrically connected to the rotary motor 2 74, output terminal No. 6 is electrically connected to the electric push rod 1 77, output terminal No. 7 is electrically connected to the electric push rod 2 8, output terminal No. 8 is electrically connected to the air conditioner indoor unit 17, output terminal No. 9 is electrically connected to the air conditioner outdoor unit 1, and output terminal No. 10 is provided with a plurality of two-hole and three-hole interfaces, which can supply power to some household appliances 18, such as: table lamps, monitors, electric fans, water purifiers, washing machines, refrigerators, air purifiers, etc.

[0055] The power distribution cabinet 16 is also provided with a display screen and an indicator light. The display screen will display the current power of the battery 14, the photovoltaic charging power, the output power of each output end, and the power supply switching button of each output end. The user can manually select the power supply mode of each output end through the power supply switching button: photovoltaic power or city power.

[0056] The input end of the power distribution cabinet 16 is divided into a photovoltaic input end and a mains input end. A power distribution control module and a power monitoring module are provided inside the power distribution cabinet. The power monitoring module can monitor the power of each electrical appliance in real time. When the photovoltaic air conditioner is installed and turned on for the first time, the power distribution control module reads the output power of the battery 14 monitored by the battery power monitoring module, and determines whether the output power of the battery 14 meets the rated power of each output end of the power distribution cabinet. If so, the battery is used for power supply. If not, the mains is used for power supply.

[0057] When the air conditioner is turned on, the crystalline silicon photovoltaic panel module 3 unfolds, receives sunlight to generate electricity and stores it in the battery. The power distribution control module detects the working power of the electrical appliances at each output end in combination with the power monitoring module, and compares it with the output power of the battery 14. If the output power of the battery 14 is lower than the working power of all the electrical appliances at the output end, the power distribution control module uses the city power to power all the output ends. As the power generation time of the crystalline silicon photovoltaic panel module increases, more electricity is stored in the battery 14, and the output power of the battery 14 continues to increase. The power distribution control module can use the photovoltaic electricity stored in the battery 14 to power the electrical appliances at each output end. The power supply logic is: ① When the battery power is detected to be below 20%, the mains power is used to power all electrical appliances at the output end; ② When it is detected that the battery power reaches more than 20%, and the battery output power meets the working power of any one of the solar sensor 9, photovoltaic control module 11, power-off electromagnetic lock 10, rotary motor 1 66, rotary motor 2 74, electric push rod 1 77, and electric push rod 2 8, the power distribution control module uses the photovoltaic power stored in the battery 14 to power the output end appliance. As the crystalline silicon photovoltaic panel module 3 continues to generate electricity, the output power of the battery 14 gradually increases, and will gradually meet the working power of the output end appliances No. 1 to No. 7. If it is met, the power distribution control module switches the output end to photovoltaic power supply; ③ When it is detected that the battery power reaches more than 60% and the battery output power meets the working power of the air conditioner indoor unit, the power distribution control module switches the output terminal 8 to photovoltaic power supply; ④ When it is detected that the battery power reaches more than 90% and the battery output power meets the working power of the air conditioner outdoor unit, the power distribution control module switches the No. 9 and No. 10 output terminals to photovoltaic power supply.

[0058] In addition, the photovoltaic air conditioner has another working mode - photovoltaic power generation mode. When the air conditioner does not need to be operated and only the crystalline silicon photovoltaic panel module 3 is needed to generate electricity, this mode is started, the crystalline silicon photovoltaic panel module 3 is unfolded to receive sunlight to generate electricity and charge the battery 14. When the battery 14 is less than 30%, the power distribution control module switches the output terminal 10 to the mains power supply; when the battery 14 is ≥30%, the power distribution control module switches the output terminal 10 to photovoltaic power supply. At this time, the battery 14 is charged through the crystalline silicon photovoltaic panel module 3 while supplying power to the household appliance 18 through the output terminal 10; when the battery 14 reaches 100%, the crystalline silicon photovoltaic panel module 3 is folded and retracted, and the indicator light on the distribution cabinet lights up green, reminding the user to use the photovoltaic power in the battery through the output terminal 10 of the distribution cabinet to power some appliances in the home.

Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
