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 outdoor and external 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 relates to a control method and device of a frequency conversion air conditioner and the frequency conversion air conditioner. The control method of the frequency conversion air conditioner comprises the steps of determining a target frequency f of the air conditioner in operation according to outdoor environment temperature Tao; judging the relation between the target frequency f and a boundary point frequency f4 of a winding of a motor of an air conditioner compressor, and controlling the mode and operation frequency of the winding of the motor of the air conditioner compressoraccording to a comparison result of a frequency comparison module, and in the frequency adjusting process, if the frequency of the air conditioner is directly adjusted to the target frequency f without passing through the winding boundary point frequency f4, an oil return stop platform is inserted when the air conditioner frequency is adjusted to the target frequency f. According to the control method of the frequency conversion air conditioner, state conversion of the coil winding and the target frequency f of the air conditioner and control over air conditioner oil return can be combined, precise control over operation of the air conditioner is achieved, and the air conditioner operation energy efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of air conditioning, for example, relates to a control method, a control device and an 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 outdoor and external 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 condition...
