Air conditioner and air conditioner compressor control method and computer readable storage medium

Abstract

The invention discloses an air conditioner and an air conditioner compressor control method. The air conditioner comprises a rectifying circuit, a power factor correction (PFC) circuit and a compressor. The input end of the PFC circuit is connected to the output end of the rectifying circuit, and the output end of the PFC circuit is connected to the compressor. The air conditioner compressor control method comprises the steps of measuring the current value of the compressor; comparing the current value of the compressor with the preset current limited frequency threshold; and controlling the compressor to run at low frequency if the current value of the compressor is larger than or equal to the preset current limited frequency threshold. The invention also discloses an air conditioner and computer readable storage medium. The current of driving components of the compressor and the working temperature of a motor in the compressor can be prevented from increasing continuously, and kept in a stable state, so that the compressor is capable of running stably, and the air conditioner runs stably to provide a comfortable indoor environment.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an air conditioner, a compressor control method thereof, and a computer-readable storage medium. Background technique [0002] In a single-phase AC power input system such as a household air conditioner, the single-phase AC power from the grid usually passes through an uncontrollable full-bridge rectifier circuit first, and then outputs DC power through a PFC (Power Factor Correction) circuit, and then Connect to bulk electrolytic capacitors and loads (for example, compressors, fans, internal switching power supplies, etc.). [0003] In related technologies, as the operating frequency of the compressor increases, the heat exchange capacity increases, and the current of the compressor drive device (compressor drive circuit) and the operating temperature of the internal motor of the compressor will increase, resulting in an increase in the operating temperature of the compr...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to provide an air conditioner and its compressor control method and computer-readable storage medium, aiming at solving the current problem of increasing the heat exchange capacity of the compressor driving device (compressor) The current size of the motor drive circuit) and the operating temperature of the internal motor of the compressor will increase, resulting in the deterioration of the operating environment of the compressor, which in turn makes the compressor unable to operate stably, resulting in the technical problem that the air conditioner cannot operate stably
