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 control device of a variable frequency air conditioner as well as the variable frequency air conditioner. The control method of the variable frequency airconditioner comprises the steps that the target frequency f of air conditioner operation is determined according to the outdoor environment temperature T<ao>; and the relation between the target frequency f and the winding demarcation point frequency f4 of a motor of an air conditioner compressor is judged, and the winding mode of the motor of the air conditioner is determined according to the relation between the target frequency f and the winding demarcation point frequency f4. According to the control method of the variable frequency air conditioner, the target frequency f of the air conditioner and state switching of coil winding can be combined, so that fine control over operation of the air conditioner is achieved, and the operation energy efficiency of the air conditioner is improved.

Description

technical field [0001] The present application relates to the technical field of air conditioning, for example, to a control method of 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 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 con...
