Problems solved by technology

[0003] The air-conditioning compressor of the existing air conditioner will resonate with the casing, motor, pipeline, etc. when running at certain frequencies, resulting in poor noise and excessive pipeline stress
When the air conditioner is protected and released, it should run slowly to stabilize the system. However, depending on the indoor and outdoor working conditions, the operating load of the indoor unit is different. For some special cases, the operation process of the air conditioner compressor will be unstable. As a result, the air conditioner compressor may not operate normally, resulting in unstable operation of the compressor

Abstract

The invention discloses a control method and device for a variable-frequency air conditioner and the variable-frequency air conditioner, and belongs to the field of compressors. According to the method, the target frequency f is calculated according to the preset temperature Ts and the indoor ambient temperature Tin; whether the target frequency f is higher than the winding cut-off point frequencyf4 is judged, if f is higher than or equal to f4, the first winding manner of a motor is selected, a compressor of the air conditioner operates to reach the winding cut-off point frequency f4, the second winding manner of the motor is switched for wiring, the compressor of the air conditioner sequentially operates to reach the frequency of two pause platforms and sustains the frequency for the preset time respectively, and then the compressor of the air conditioner operates to reach the target frequency f. Whether the target frequency f is higher than the winding cut-off point frequency f4 isjudged, the first winding manner or the second winding manner of the motor is selected for wiring, and then the operation frequency and the operation time of the compressor at each pause platform arecontrolled, so that the compressor operates stably and reliably.

Description

technical field [0001] The present application relates to the technical field of air conditioning, for example, to a control method and device for an inverter air conditioner and the inverter air conditioner. Background technique [0002] At present, with the development of the economy and the improvement of living standards, people have a higher demand for inverter air conditioners with better comfort adjustment and energy saving. [0003] The air-conditioning compressor of the existing air conditioner will resonate with the shell, the motor, the pipeline, etc. when running at certain frequencies, resulting in poor noise and excessive pipeline stress. When the air conditioner is protected and released, it should run slowly to stabilize the system. However, depending on the indoor and outdoor working conditions, the operating load of the indoor unit is different. For some special cases, the operation process of the air conditioner compressor will be unstable. As a result, t...
