Abstract

The invention provides a control method and a device of an air conditioner and the air conditioner. The method comprises the following steps: a first control policy and / or a second control policy are / is carried out; the step of carrying out the first control policy comprises the following substeps: a first target frequency of a compressor is determined; a frequency shielding interval of the compressor is determined according to a rotating speed and a blade number of an outdoor fan; and when the first target frequency is in the frequency shielding interval, the operation of the compressor is controlled according to a set temperature of the air conditioner, an indoor environment temperature and the frequency shielding interval; and / or, the step of carrying out the second control policy comprises the following substeps: a first target rotating speed of the outdoor fan is determined; a rotating speed shielding interval of the outdoor fan is determined according to an operation frequency ofthe compressor and the blade number of the outdoor fan; and when the first target rotating speed is in the rotating speed shielding interval, the operation of the outdoor fan is controlled accordingto a temperature of an outdoor heat exchanger, an outdoor environment temperature and the rotating speed shielding interval. The method can reduce the beat vibration of the compressor and the outdoorfan.

Description

technical field [0001] The invention relates to the field of control, in particular to an air conditioner control method, device and air conditioner. Background technique [0002] When the frequency conversion air conditioner is running, if the operating speed of the outdoor fan and the operating frequency of the compressor meet certain conditions, the external fan will generate beating vibrations (the fan, the casing, and the compressor resonate, producing discontinuous "whirling" sounds), which seriously affects the performance of the outdoor unit. sound quality. The traditional inverter air conditioner solves beating vibration by shielding the operating frequency point of the compressor for the beating vibration point, but this method reduces the operating frequency of the compressor, making the inverter air conditioner run close to the fixed frequency air conditioner, and this control makes the temperature control of the inverter air conditioner The accuracy becomes poo...
