Problems solved by technology

[0003] 1. When the power supply of the solar battery is insufficient, it is powered by the battery. However, the installation of the battery takes up space, and the service life of the battery is short, so it needs to be replaced regularly, which is costly and inconvenient to operate;
[0004] 2. When the solar battery power supply is insufficient, once the DC voltage output by the inverter of the solar air conditioner is lower than the voltage of the mains grid, it will immediately change to the mains grid for power supply, and the consumption cost is high

Abstract

The invention provides a control method for a solar air conditioner. The control method comprises the detection step and the judgment step. In the detection step, when it is detected that the solar air conditioner enters an energy-saving control mode, the change conditions of DC voltage output by an inverter in the solar air conditioner are started to be detected. In the judgment step, according to the change conditions of the DC voltage, the operation frequency of a compressor in the solar air conditioner is adjusted so that the solar air conditioner can be charged through a solar battery. Correspondingly, the invention further provides a control device of the solar air conditioner and the solar air conditioner. According to the technical scheme, solar energy can be utilized to the maximum degree, so that the problem that a mains supply is required due to a solar power shortage is avoided, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular, to a control method for a solar air conditioner, a control device for a solar air conditioner, and a solar air conditioner. Background technique [0002] There are two main options for existing solar air conditioners: [0003] 1. When the power supply of the solar battery is insufficient, it is powered by the battery. However, the installation of the battery takes up space, and the service life of the battery is short, so it needs to be replaced regularly, which is costly and inconvenient to operate; [0004] 2. When the power supply of the solar battery is insufficient, once the DC voltage output by the inverter of the solar air conditioner is lower than the voltage of the mains grid, it will be immediately changed to the mains grid for power supply, and the consumption cost is high. [0005] Therefore, how to operate the air-conditioning system by using solar energy to ...
