Abstract

Embodiments of the invention disclose an inverter compressor frequency adjusting method and device, equipment and a storage medium. According to the embodiments of the invention, the vibration amplitude of a unit is detected in the frequency increasing or decreasing adjustment process of a compressor, and the frequency is adjusted when the vibration amplitude of the unit exceeds a preset vibrationthreshold value, so that the vibration amplitude of the unit is lower than the vibration threshold value; and meanwhile, the vibration amplitudes of the unit under different operation frequencies anddifferent operation working conditions of the compressor are recorded, and an operation record chart is generated in order to determine the optimal operating frequency of next operation of the unit.By the adoption of the technical means, the problem that an existing compressor unit is too large in vibration amplitude can be solved, the operating frequency of the compressor is adjusted accordingto the actual working condition of the compressor, then the vibration amplitude of the unit is adjusted in real time, a good unit vibration amplitude adjusting effect is achieved, and the compressor unit is prevented from being damaged due to excessive vibration.

Description

technical field [0001] The embodiments of the present application relate to the technical field of compressor vibration reduction, and in particular to a frequency adjustment method, device, equipment and storage medium of an inverter compressor. Background technique [0002] As a power source, the compressor is a device that upgrades low-pressure gas to high-pressure gas, and is the heart of the refrigeration system of electrical appliances. At present, when the compressor is working, the problem of excessive vibration amplitude of the compressor unit often occurs. This problem may be caused by the resonance of the unit during the compressor frequency adjustment process, or it may be caused by a sudden change in system pressure when the compressor is shut down. Therefore, in order to solve the problem of excessive vibration amplitude of the compressor unit, reduce the noise generated by vibration, and prevent the unit from being damaged due to excessive vibration, the expe...
