Air conditioner control method and air conditioner

Abstract

The invention provides a control method for an air conditioner and the air conditioner. The air conditioner comprises a solar power generation part, an energy storage part, an external power interface and a power utilization part. The control method includes the steps that the set target temperature and the temperature of the environment where the air conditioner is located are obtained respectively, and the temperature difference between the target temperature and the temperature of the environment is calculated; the temperature difference is compared with the preset temperature threshold; in the situation that the temperature difference is larger than or equal to the temperature threshold, one of the solar power generation part, the energy storage part and an external power source is selected according to the voltage value of the solar power generation part and the voltage of the energy storage part for supplying power to the power utilization part, and a compressor in the power utilization part is controlled to operate according to the preset frequency; and in the situation that the temperature difference is smaller than the temperature threshold, the compressor is controlled to run according to the preset frequency or run according to the frequency lower than the preset frequency. According to the scheme, consumption of external electric energy is reduced, and the energy utilization efficiency is improved.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to an air conditioner control method and the air conditioner. Background technique [0002] With the gradual increase of users' awareness of energy saving and emission reduction, and the development of renewable energy technologies such as solar energy, solar power generation components of solar panels are installed on or near the surface of the outdoor unit of the air conditioner in the prior art, and the electric energy converted by solar energy is used to supply power to the air conditioner. [0003] The existing solar-powered air conditioners in the current technology mainly use two power supply modes, one is to directly invert the electric energy generated by solar energy into commercial power, and directly provide it to the air conditioner. This method is greatly affected by the intensity of sunlight due to solar power supply. , and the conversion efficiency of the inve...

Problems solved by technology

However, using this method for power supply, on the one hand, the energy storage component is always in working condition, which shortens the effective service life of the energy storage component, and in addition, the electric energy of the energy storage component itself will also be lost, resulting in a waste of electric energy

Moreover, due to the different working conditions of the air conditioner, the required electric power is also different. Using the same power supply method for different working conditions will also affect the reliability of the power supply components.
