Abstract

The invention relates to a frequency-conversion air conditioner with a solar cell, comprising the solar cell, a frequency-conversion air conditioner, a solar power supply controller connected between the solar cell and the frequency-conversion air conditioner and a mains supply, wherein the frequency-conversion air conditioner comprises an AC / DC rectifier and a direct-current frequency-conversion air conditioner circuit, and the solar power supply controller comprises a DC / high-voltage DC inverter and a maximum power tracker; and the maximum power tracker monitors the output power of the solar cell and controls the DC / high-voltage DC inverter to convert low-voltage direct current outputted by the solar cell to high-voltage direct current for directly supplying power to the direct-current frequency-conversion air conditioner circuit. After passing through the AC / DC rectifier, the mains supply is connected with the solar power supply controller in parallel to supply power to the direct-current frequency-conversion air conditioner circuit. The invention accords with the development direction of national energy saving and environmental protection, has the characteristics of simple and reasonable structure, low manufacturing cost, energy saving, environmental protection, reduced influence on environment, flexible operation, high energy efficiency ratio and wide range of application.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an inverter air conditioner with solar cells. Background technique [0002] Existing solar air conditioners driven by solar cells, see attached figure 1 , the solar battery 1 is managed by the solar power supply controller 9, the battery 10 and the DC / high voltage DC inverter 11 are powered, and then converted into the same AC voltage as the mains through a high voltage DC / 50 or 60Hz high voltage AC converter 13 . Simultaneously, the solar power supply controller 9 detects whether the electric quantity of the solar cell 1 and the storage battery 10 is sufficient, controls the electronic switch 14, and when the electric quantity of the solar cell 1 and the storage battery 10 is not enough, controls the electronic switch 14 to switch to the mains 5 for frequency conversion. Air conditioner 15 supplies power, otherwise, switch to high-voltage DC / 50 or 60Hz high-voltage AC converter 13 to supp...
