The invention discloses a UPS power supply air conditioner control method. When the electric supply breaks off, a storage battery in a UPS supplies electricity to an air conditioner. The UPS detects the UPS real-time output power P0, and if the UPS real-time output power P0 is larger than the UPS rated load Ps, the UPS generates an overload alarm signal and outputs the overload alarm signal to a control chip of the air conditioner. After the control chip of the air conditioner receives the overload alarm signal, a compressor is controlled to run according to the first overload running frequency Pp1, the first overload running frequency Pp1 is smaller than the practical running frequency P1, and the compressor maintains the first overload running frequency Pp1 to run; and the UPS detects the feedback output power Pf generated by the compressor running according to the first overload running frequency Pp1, and if the feedback output power Pf is smaller than or equal to the rated load Ps, the compressor maintains the first overload running frequency Pp1 to run till the electric supply recovers or the terminal voltage of the storage battery drops to zero. The invention further discloses the air conditioner. The UPS power supply air conditioner control method and the air conditioner have the beneficial effects that the automation degree is high, and the user experience is good.
Description
Technical field [0001] The invention relates to the technical field of air conditioning, in particular to a UPS-powered air conditioner control method and an air conditioner adopting the control method. Background technique [0002] In some economically backward countries and regions, such as Ethiopia in Africa, Pakistan in Asia and other countries, the coverage rate of power users is only 20% to 40%, the quality of power supply is also very poor, the voltage and frequency of the power supply fluctuate greatly, and the waveform is distorted. Seriously, the power supply may be interrupted at any time. Ordinary household appliances, such as lighting equipment, are generally powered by batteries. [0003] However, for hospitals, bank clearing centers, civil aviation, meteorology and other departments, air conditioners are also required to maintain normal operation. In order to avoid air conditioners from stopping, they are generally equipped with UPS power supplies. Because these ar...
