Embodiment 1

[0030] like figure 1 As shown, it is the solar air conditioner of Embodiment 1 of the present invention, wherein the solar air conditioner 10 includes a solar power generation unit 101, which generates electric energy through the irradiation of the sun; an inverter air conditioner unit 106, which adopts a DC inverter compressor, and the compressor The power supply adopts high-voltage direct current, and the high-voltage direct current can be generated by the mains through inverter, and / or after the solar power generation unit 101 boosts the voltage, since the mains inverter and the two power supply coordination power supply devices are existing technology, not further described in the description, not shown in the figure; DC-DC conversion unit 102, used to increase the current voltage from the solar power generation unit 101, one end of the DC-DC conversion unit is connected to the solar power generation unit The output end of 101, the other end is connected to the main contro...

Embodiment 2

[0034] like figure 2 As shown, it is the solar air-conditioning device of Embodiment 2 of the present invention, wherein the difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 adds an MPPT unit on the input side of the solar power generation unit 101, and the MPPT unit is "Maximum Power Point Tracking "(Maximum Power Point Tracking), means that the controller can detect the power generation voltage of the solar panel in real time, and track the highest voltage and current value (VI), so that the system can charge the battery with the highest efficiency. The solar energy can be fully converted to generate electrical energy, so as to improve the energy efficiency of the solar power generation unit 101 . The generated electric energy is output to the power storage unit 104 and / or the DC-DC unit. An active filtering unit 109 is also provided between the DC-AC unit 107 and the AC power supply 108. The active filtering is to allow signals within a certain freque...

Embodiment 3

[0036] like image 3 As shown, it is the solar air conditioner of the third embodiment of the present invention, wherein the difference between the third embodiment and the first embodiment is that the third embodiment is provided with a DC -DC conversion unit, the power storage unit 104 outputs electric energy to the DC-DC unit 105, the DC-DC unit 105 is used to increase the current voltage from the power storage unit 104, and one end is connected to the output end of the solar power generation unit 101 , the other end is connected to the main control unit 103, and the main control unit 103 controls the output of electric energy. In this way, the external power supply of the solar power generation unit 101 and the power storage unit 104 will not be affected, and a more flexible power supply can be realized.

Abstract

The invention discloses a solar air conditioner and a solar air-conditioning system consisting of the solar air conditioner. The solar air conditioner comprises a solar electrical energy generation unit, a DC-DC converting unit, a main control unit and a variable frequency air-conditioning unit connected in turn, wherein the solar electrical energy generation unit and the DC-DC converting unit are connected to an electric power storage unit together; and the solar air-conditioning system comprises the solar air conditioner and at least one set of additional solar air conditioners. The solar air conditioner and the solar air-conditioning system can invert and transmit redundant electrical energy to the mains supply after the electric power storage unit is charged through a DC-AC inverter, so the solar air conditioner and the solar air-conditioning system are favorable for energy saving and emission reduction of an electric power system. But the solar air-conditioning system can combine a plurality of the solar air conditioners for use, uniformly uses each solar electrical energy generation unit to supply power to the variable frequency air-conditioning unit, or supplies the generated electrical energy to the mains supply by using a uniform electrical power transmission unit.

Description

technical field [0001] The invention relates to an air conditioner, especially a solar air conditioner that uses solar power to supply frequency conversion air conditioners; and a solar air conditioner system composed of the device. Background technique [0002] With the increasing awareness of energy saving and emission reduction among ordinary consumers, air conditioners using new energy have gradually moved from the laboratory to the market, especially the outdoor units of air conditioners installed outside the room, and those with solar panels or solar panels installed on the roof. In the form of converting solar energy into electric energy and using it when the air conditioner is running, it can effectively reduce the consumption of commercial power and achieve the purpose of energy saving and emission reduction. Furthermore, since solar energy is only collected when there is sun, and the time when users use air conditioners does not coincide with the time when there is...
