Detailed Description
As shown in fig. 1 to 3, the present invention discloses a solar power supply system for a vehicle/ship ac air conditioner, which comprises a solar panel 10, a dc generator 20, a starting battery 40, and a solar charging and inverting integrated machine 30; the solar panel 10 is connected with the solar charging and inverting integrated machine 30, the starting battery 40 is connected with the solar charging and inverting integrated machine 30 through a first direct current switch, the direct current generator 20 is connected with the solar charging and inverting integrated machine 30 through a second direct current switch, the solar charging and inverting integrated machine 30 is provided with an alternating current air conditioner load output end, and the alternating current air conditioner load output end is connected with the alternating current air conditioner 50.
Specifically, the solar charging and inverting integrated machine 30 includes a bypass unit 31, a solar charger unit 32, a battery charging unit 33, a charging/inverting unit 35, a transformer unit 36, and an MCU controller unit 34.
The input end of the bypass unit 31 is used for connecting with the commercial power, and the output end is connected with the alternating current air conditioner load output end of the solar charging and inverting integrated machine 30. This bypass unit 31 still connects the MCU the control unit, and when parking, shut down or idle speed operation, and this bypass unit 31 inserts the commercial power, this bypass unit 31 of MCU the control is opened, and the commercial power is the direct power supply for exchanging air conditioner 50. Meanwhile, the MCU control unit can also control commercial power to charge the starting storage battery 40, and the commercial power can charge the starting storage battery 40 through the transformer unit 36 and the charging/inverting unit 35.
The input end of the solar charger unit 31 is connected with the solar panel 10, and the output end is connected with the input end of the battery charging unit 33 on one hand and the input end of the charging/inverting unit 35 on the other hand; the output end of the storage battery charging unit 33 is connected to a starting storage battery, and the starting storage battery is connected to the input end of the charging/inverting unit; the input end of the charging/inverting unit 35 is also connected with a direct current generator, and the output end is connected with the input end of the transformer unit; the output end of the transformer is connected with the alternating current air conditioner load output end of the solar charging inversion integrated machine;
the MCU controller is provided with a voltage detection end, a solar charging control end, a battery charging control end, a charging/inverting control end, a generator control end and a bypass control end. The voltage detection end is connected with the solar panel 10, the solar charging control end is connected with the solar charger unit 32, the battery charging control end is connected with the battery charging unit 33, and the generator control end is connected with the direct current generator 20. The MCU controller detects the output voltage of the solar panel 10 through the voltage detection terminal to determine the illumination intensity of the solar panel 10. When the detected output voltage of the solar panel 10 is greater than V1, which indicates that the illumination intensity of the solar panel 10 is high, the MCU controller controls the solar charger unit 32 to perform voltage reduction processing, and simultaneously the MCU also controls the level charger unit to open. At this time, the solar panel 10 supplies power to the ac air conditioner 50 through the solar charging and inverting integrated machine 30 and charges the starting battery 40. When the detected output voltage of solar panel 10 is between V2 and V1, it indicates that the intensity of light received by solar panel 10 is moderate, and the energy generated by solar panel 10 is only enough to supply ac air conditioner 50. At this time, the MCU controller unit 34 controls the solar charger unit 32 to output normal voltage, and turns off the battery charging unit 33, so that the solar panel 10 supplies power to the ac air conditioner 50 through the solar charger unit 32, the charging/inverting unit 35, and the transformer unit 36. When the output voltage of solar panel 10 is less than V2, it means that the intensity of solar light is low and the energy generated by solar panel 10 is insufficient for ac air conditioner 50. At the moment, if the direct current generator is in a working state, the MCU controller unit controls the direct current generator and the solar panel to jointly supply power to the alternating current air conditioner; if the direct current generator is turned off, the MCU control unit controls the storage battery charging unit to be turned on, and the storage battery and the solar panel are started to supply power to the alternating current air conditioner together.

At this time, the MCU controller unit 34 turns on the battery charging unit 33 and controls the charging/inverting unit 35 to be in the charging mode, the commercial power is charged to the starting battery 40 through the transformer unit 36, the charging/inverting unit 35 and the battery charging unit 33, and the solar panel 10 is also charged to the starting battery 40 through the solar charger and the battery charging unit 33.
The starting storage batteries 40 with different capacities correspond to different charging currents. Therefore, the MCU controller is also provided with a current detection end which is connected with the output end of the solar charger. The user determines the corresponding charging current according to the capacity of the set starting battery 40.
The MCU controller is also connected with a liquid crystal monitor. The liquid crystal monitor communicates with the solar charging and inverting integrated machine 30 through a 485 communication protocol, and reads information such as the running state and data of the whole power supply system in real time.

The MCU processor can also be connected with a dial switch for setting a working mode, an AC/DC main mode, battery low-voltage protection point presetting, battery type setting, equalizing charging, an energy-saving mode and AC charger setting.
Based on the alternating current air conditioner solar power supply system, the invention also discloses a vehicle/ship alternating current air conditioner solar power supply method, which comprises the following steps:
the solar charging and inverting integrated machine 30 collects the output voltage value of the solar panel 10, when the output voltage value of the solar panel 10 (hereinafter referred to as PV) meets the input range requirement (generally under the condition of sufficient illumination), the MCU controller unit 34 controls the battery charging unit 33 to be turned on, and the solar panel 10 supplies power to the ac air conditioner 50 through the solar charging and inverting integrated machine 30 and charges the starting battery 40;
a) when the PV output voltage is greater than V1, which indicates that the input energy of the solar panel 10 is high (the solar panel 10 is illuminated with high intensity), the MCU controller unit 34 controls the solar charger unit 32 to perform voltage reduction processing and controls the battery charger to be turned on; the solar panel 10 supplies power to the alternating current air conditioner 50 and charges the starting battery 40 through the solar charging and inverting integrated machine 30;
b) when the PV output voltage is between V2 and V1, indicating that the input energy of the solar panel 10 is normal (the solar panel 10 is illuminated with moderate intensity), the MCU controller unit 34 controls the solar charger unit 32 to output normal voltage, and turns off the battery charging unit 33, so that the solar panel 10 supplies power to the ac air conditioner 50 through the solar charger unit 32, the charging/inverting unit 35, and the transformer unit 36.
c) When the PV output voltage is less than V2, it indicates that the input energy of the solar panel 10 is weak (the solar panel 10 is low in illumination intensity), if the DC generator is in a working state, the MCU controller unit controls the DC generator and the solar panel to supply power to the AC air conditioner together; if the direct current generator is turned off, the MCU control unit controls the storage battery charging unit to be turned on, and the storage battery and the solar panel are started to supply power to the alternating current air conditioner together.
In the process that the solar panel 10 supplies power to the ac air conditioner 50, the MCU controller controls the charging/inverting unit 35 to be in the inverting operation mode.
The solar charging and inverting integrated machine 30 is provided with a bypass unit 31, and the commercial power can directly supply power to the ac air conditioner 50 through the bypass unit 31. Specifically, when the bypass unit 31 is connected to the commercial power, the MCU controller unit 34 controls the bypass unit 31 to be opened, and the commercial power directly supplies power to the ac air conditioner 50 through the bypass unit 31. At this time, the MCU controller unit 34 turns on the battery charging unit 33 and controls the charging/inverting unit 35 to be in the charging mode, the commercial power is charged to the starting battery 40 through the transformer unit 36, the charging/inverting unit 35 and the battery charging unit 33, and the solar panel 10 is also charged to the starting battery 40 through the solar charger and the battery charging unit 33.
In summary, during the daytime running of the vehicle/ship, the solar panel 10 collects solar energy, and the solar charging and inverting integrated machine 30 inverts the direct current into 230Vac/50Hz alternating current for the ac air conditioner 50 of the vehicle/ship. Under the condition of sufficient illumination, the solar energy can meet the refrigeration/heat requirement of the alternating-current air conditioner 50 in daily driving; when the obtained solar energy is larger than the energy required by the alternating current air conditioner 50, the redundant solar energy can be used by other direct current load equipment through the original vehicle starting storage battery 40, and the solar energy is utilized to supply power to the maximum extent.
In the parking/idling operation state, when the illumination is sufficient, the solar energy can meet the daily driving refrigeration/heating requirement of the alternating current air conditioner 50; when the obtained solar energy is larger than the energy required by the alternating current air conditioner 50, the redundant solar energy can be used by other direct current load equipment through the original vehicle starting storage battery 40, and the solar energy is utilized to supply power to the maximum extent. When the illumination is weak, the solar panel 10 and the vehicle/ship direct current generator 20 generate electricity to supply power to the charging and inverting integrated machine together, and the direct current is inverted into 230Vac/50Hz alternating current to be used by the alternating current air conditioner 50 of the vehicle.
In the vehicle/vessel flameout state: when the illumination is sufficient, the solar energy can meet the refrigeration/heat requirement of the alternating-current air conditioner 50 in daily driving; when the obtained solar energy is larger than the energy required by the alternating current air conditioner 50, the redundant solar energy can be used by other direct current load equipment through the original vehicle starting storage battery 40, and the solar energy is utilized to supply power to the maximum extent. When the illumination is weak, the solar energy and the original vehicle starting battery 40 of the vehicle discharge to supply power to the solar charging and inverting integrated machine 30 together, and the direct current is inverted into 230Vac/50Hz alternating current for the alternating current air conditioner 50 to use; when the battery 40 is started to continue discharging to the direct-current low-voltage protection value of the solar charging and inverting integrated machine 30, power supply is stopped, and the solar power supply system is closed.
The key point of the invention is that the invention takes the solar energy as the main energy source of the AC air conditioner 50, and when the energy of the solar energy is more, the redundant energy is input into the starting storage battery 40; when the solar energy is less, the AC air conditioner 50 is powered by the DC generator 20 or the starting battery and the solar panel 10. Thereby effectively reducing the oil consumption of the vehicle and realizing energy conservation and emission reduction. Meanwhile, after the vehicle is flamed out, the alternating current air conditioner can still work normally, so that the environmental noise of the cab is reduced to a great extent, and a comfortable cab environment is created for drivers and passengers.
