The present invention provides a solar air conditioner, as shown in fig. 1, comprising: solar panel 2, energy memory 1, air conditioner body and control system.
In this embodiment, the solar panel 2 is an assembly of a plurality of solar cells, and is a core part in the solar air conditioner, and is used for receiving solar energy and outputting electric energy.
The input end of the energy storage device 1 is connected with the solar panel 2, and the energy storage device 1 is used for storing solar energy when the air conditioner does not work or the output electric energy is large. The air conditioner body can be any air conditioner, such as a wall-mounted air conditioner, a vertical cabinet air conditioner, a window air conditioner, a ceiling air conditioner and the like. The air conditioner body in this embodiment includes: the indoor unit 3 and the outdoor unit 4, and the indoor unit 3 and the outdoor unit 4 are provided with a direct current load and an alternating current load.

Similarly, the alternating current load is an alternating current motor or a compressor, or is of two structures of the alternating current motor and the compressor.
The control system is used for detecting whether the output electric energy of the solar panel 2 meets the power supply requirement of the air conditioner body. And if the output electric energy of the solar panel 2 meets the power supply requirement of the direct current load and/or the alternating current load in the air conditioner body, controlling the solar panel 2 to be electrically connected with the direct current load and/or the alternating current load meeting the power supply requirement.
Specifically, when the control system determines that the output electric energy of the solar panel 2 meets the power supply requirement of the dc load, the control system controls the solar panel 2 to be electrically connected with the dc load meeting the power supply requirement. When the control system judges that the output electric energy of the solar panel 2 meets the power supply requirement of the alternating current load, the control system controls the solar panel 2 to be electrically connected with the alternating current load meeting the power supply requirement. When the control system judges that the output electric energy of the solar panel 2 simultaneously meets the power supply requirements of the direct current load and the alternating current load, the control system controls the solar panel 2 to be simultaneously electrically connected with the direct current load and the alternating current load meeting the power supply requirements. When solar panel 2 can satisfy the part power supply requirement in the solar air conditioner promptly, can directly utilize solar panel 2 to supply power to corresponding part. The energy consumption of the corresponding components can thereby be reduced.
The components meeting the power supply requirements of the solar panel 2 are supplied with power by the solar panel 2.

Meanwhile, the residual electric quantity is compared with the preset electric quantity, and according to the judgment result, the connection states of the energy storage device, the commercial power circuit and the direct current load and the alternating current load which do not meet the power supply requirement in the solar air conditioner are controlled, so that the air conditioner can work stably as much as possible, and the energy consumption of the air conditioner is reduced.
In order to switch the power supply mode, a rectifier and a change-over switch 7 can be additionally arranged. A rectifier is a device that converts alternating current to direct current. The change-over switch 7 is electrically connected with the control system, and the change-over switch 7 is provided with a first station, a second station and a third station.
When the change-over switch 7 is at the first station, the energy storage device 1 is electrically connected with the direct current load which does not meet the power supply requirement, and the commercial power circuit 6 is electrically connected with the alternating current load which does not meet the power supply requirement, so that the power consumption of the direct current load can be reduced. Meanwhile, the alternating current load which does not meet the power supply requirement is directly supplied by the commercial power, so that the situation that the fluctuation of the solar energy supply voltage to the part is influenced on the work of the air conditioner can be effectively avoided.
When the change-over switch 7 is at the second station, the energy storage device 1 is simultaneously electrically connected with the direct current load which does not meet the power supply requirement and the alternating current load which does not meet the power supply requirement, and the energy storage device 1 can be completely utilized to supply power to the components which do not meet the power supply requirement.
When the change-over switch 7 is in the third station, one end of the commercial power circuit 6 is electrically connected with the alternating current load which does not meet the power supply requirement, and the other end of the commercial power circuit 6 is electrically connected with the direct current load which does not meet the power supply requirement through the rectifier, so that the commercial power can be completely utilized to supply power to the components which do not meet the power supply requirement.
Wherein, the air conditioner still includes: a first inverter 5. The inverter can convert the direct current electric energy (batteries and storage batteries) into constant-frequency constant-voltage or frequency-modulation voltage-regulation alternating current. The energy storage device 1 is provided with a first supply terminal and a second supply terminal. When the change-over switch 7 is in the first station, the first power supply end of the energy storage device 1 is electrically connected with the direct current load which does not meet the power supply requirement, and the commercial power circuit 6 is electrically connected with the alternating current load which does not meet the power supply requirement.

In addition, the air conditioner further includes: and a second inverter 8. Correspondingly, solar panel 2 is equipped with first output and second output. The first output end of the solar panel 2 is electrically connected with a direct current load meeting the power supply requirement sequentially through the second inverter 8 and the rectifier, the second output end of the solar panel 2 is electrically connected with an alternating current load meeting the power supply requirement through the second inverter 8, and the solar panel 2 can supply power for the direct current load and the alternating current load meeting the power supply requirement by arranging the second inverter 8.
The invention provides a control method of a solar air conditioner, which is shown in figures 1 and 2. The control method can be used for controlling the solar air conditioner.
As shown in fig. 1, the control method of the solar air conditioner according to the embodiment of the present invention includes the following steps: S110-S140.
Step S110: whether the output electric energy of the solar panel meets the power supply requirement of the solar air conditioner is detected.
Before the solar air conditioner is powered on and started, the control system of the solar air conditioner controls the sensor to acquire the output electric energy of the solar panel 2 and acquires the power supply requirement of the solar air conditioner, wherein the power supply requirement comprises the following steps: and the power supply requirements of each direct current load and each alternating current load in the solar air conditioner.
Step S120: and if the output electric energy meets the power supply requirement of the direct current load and/or the alternating current load in the solar air conditioner, controlling the solar panel to be electrically connected with the direct current load and/or the alternating current load meeting the power supply requirement.
When the control system judges that the output electric energy of the solar panel 2 meets the power supply requirement of the direct current load, the control system controls the solar panel 2 to be electrically connected with the direct current load meeting the power supply requirement.
When the control system judges that the output electric energy of the solar panel 2 meets the power supply requirement of the alternating current load, the control system controls the solar panel 2 to be electrically connected with the alternating current load meeting the power supply requirement.
When the control system judges that the output electric energy of the solar panel 2 simultaneously meets the power supply requirements of the direct current load and the alternating current load, the control system controls the solar panel 2 to be simultaneously electrically connected with the direct current load and the alternating current load meeting the power supply requirements. When solar panel 2 can satisfy the part power supply requirement in the solar air conditioner promptly, can directly utilize solar panel 2 to supply corresponding part, reducible corresponding part's energy consumption from this.
Step S130: and acquiring the residual electric quantity in the energy storage device, and judging whether the residual electric quantity reaches the preset electric quantity.
After the partial equipment meeting the power supply requirement in the solar air conditioner is powered on, the control system of the solar air conditioner controls the sensor to acquire the residual electric quantity in the energy storage device 1. After the sensor acquires the residual electric quantity of the energy storage device 1, the control system reads the information of the residual electric quantity.
After acquiring the remaining power and the power supply information, the control system determines whether the remaining power reaches a preset power, for example, whether the remaining power reaches 80% of the total power, and if the remaining power reaches 80%, it indicates that the remaining power reaches the preset power. If not, the residual capacity does not reach the preset capacity.
The preset electric quantity is set according to the user requirement, for example, the energy storage device 1 set by the user needs to ensure that when the air conditioner operates for two hours, the residual electric quantity at least meets the requirement that Δ E is 80% × E is p × h. Wherein, Δ E is the residual electric quantity, E is the total electric quantity, p is the power of the solar air conditioner, and h is the time.
Meanwhile, the control system can also control another sensor to acquire the power supply information of the commercial power. The power supply information includes at least: current, power, and voltage. And judging whether the power supply information meets the preset power supply working condition. The control system can determine whether the power supply is normal or not according to the power supply information, for example, when the mains supply is powered off or serious voltage fluctuation occurs, the control system judges that the power supply information does not meet the preset power supply working condition.
Step S140: and controlling the connection state of the energy storage device and the commercial power circuit with the direct current load and the alternating current load which do not meet the power supply requirement in the solar air conditioner according to the judgment result.
The control system of the solar air conditioner judges that the acquired residual electric quantity exceeds the preset electric quantity, and when the power supply information meets the preset power supply working condition, for example, the residual electric quantity exceeds 80% of the total electric quantity, and the mains voltage meets the rated voltage and is stable, the control system controls the change-over switch 7 to be positioned at the first station, the energy storage device 1 is electrically connected with a direct current load which does not meet the previous power supply requirement in the solar air conditioner, and the mains circuit 6 is electrically connected with an alternating current load which does not meet the previous power supply requirement.
The solar panels 2 only supply power for a part of the loads that meet the power supply requirements. The energy storage device 1 only supplies power for the direct current load which does not meet the power supply requirement, so that the power consumption of the direct current motor and/or the direct current circuit board can be reduced, and the load can not cause great influence on the work of the air conditioner when the voltage or the current fluctuates. Whereas the alternating current of the mains circuit 6 only supplies alternating current loads which do not meet the supply requirements. For example, the commercial power circuit 6 can supply power to the alternating current motor and/or the compressor, and since the alternating current load is directly supplied by the commercial power, the influence of the fluctuation of the solar energy supply voltage on the work of the air conditioner can be effectively avoided.
If the control system of the solar air conditioner judges that the obtained residual electric quantity exceeds the preset electric quantity and the power supply information does not meet the preset power supply working condition, the energy storage device 1 is controlled to be simultaneously and electrically connected with the direct current load and the alternating current load.
For example, when power failure or voltage instability occurs, the control system controls the change-over switch 7 to be located at the second station, the energy storage device 1 is provided with the first power supply end and the second power supply end by arranging the first inverter 5, the first power supply end of the energy storage device 1 is electrically connected with a direct current load which does not meet the power supply requirement, the second power supply end of the energy storage device 1 is electrically connected with an alternating current load which does not meet the power supply requirement through the first inverter 5, and the energy storage device 1 can be completely used for supplying power to a partial structure which does not meet the power supply requirement of the solar panel 2 in the solar air conditioner.
