A control method of a variable-frequency air conditioner comprises the following steps that a power supply control mechanism achieving city power supplying and an emergency control mechanism achieving storage battery power supplying are stored in the variable-frequency air conditioner; city power is broken off, the emergency control mechanism is called by a controller of the variable-frequency air conditioner, the input variable of the emergency control mechanism is a storage battery electric quantity signal, and the output variable of the emergency control mechanism is the frequency of a compressor, the rotary speed of an outdoor draught fan and / or the rotary speed of an indoor draught fan; and the storage battery electric quantity signal is divided into a plurality of grades, and a compressor frequency signal, an outdoor draught fan rotary speed signal and / or an indoor draught fan rotary speed signal which correspond to the storage battery electric quantity signal of each grade are output by the controller by. The invention further provides a control device and the variable-frequency air conditioner. The compressor, the indoor draught fan and the outdoor draught fan continuously operate under different operating rotary speeds according to the magnitude of the electric quantity of a storage battery, fluctuation of the temperature in an air conditioner room is small in the operating process, the compressor does not stop, and meanwhile the time of the storage battery for supplying power to the air conditioner is prolonged.
Description
technical field [0001] The invention relates to the technical field of air conditioning, and in particular, to a control method, a control device and a frequency conversion air conditioner for an inverter air conditioner. Background technique [0002] The refrigeration system used in the inverter air conditioner is to meet the requirements of the indoor cooling and heating load in a timely manner by controlling the refrigerant circulation volume of the compressor and the refrigerant flow into the indoor heat exchanger. Usually, this kind of air conditioning system adopts inverter compressor, multi-stage compressor, unloading compressor or combination of multiple compressors to realize compressor capacity control. Electronic expansion valves and other auxiliary circuits are set in the refrigeration system to adjust the refrigerant flow into the indoor unit, and the capacity of the heat exchanger is adjusted by controlling the fan speed of the indoor and outdoor heat exchanger...
