Embodiment Construction

[0022] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] figure 1 It is a flowchart of a method for starting an inverter compressor according to an aspect of the present invention. exist figure 1 middle:

[0024] Step S100: Increase the frequency of the inverter compressor from the initial frequency to a first intermediate frequency. Wherein, the initial frequency may be 0 Hz. Preferably, the first intermediate frequency may be between 40 Hz and 60 Hz. The first intermediate frequency can be found through the oil return quantity of the inverter compressor. For example, look for a low frequency in the starting frequency of the variable frequency compressor, and then observe the oil return amount of the variable...

Abstract

The invention provides a method for starting a variable frequency compressor. According to the method, the frequency of the variable frequency compressor is raised to an intermediate frequency in the frequency raising process after the variable frequency compressor is started, and the intermediate frequency is kept for predetermined time, wherein the predetermined time is not shorter than the frequency modulation period of the variable frequency compressor. By the method for starting the variable frequency compressor, the reliability of the variable frequency compressor can be improved, abrasion of the variable frequency compressor is reduced, and the service life of the variable frequency compressor is prolonged; and by tripping certain frequency values of the variable frequency compressor in the starting process of the compressor, resonance between the compressor and a system pipeline is avoided, and the quality risk is avoided.

Description

technical field [0001] The present invention basically relates to the field of electrical appliances, and more specifically, relates to a method for starting an inverter compressor. Background technique [0002] During the start-up process of the inverter compressor, the bearings and the crankshaft, piston and cylinder are abnormally worn when they are running in the high frequency band, which leads to the overheating of the compressor and the aging of the windings and internal insulation materials. , It is easy to generate resonance phenomenon at a certain frequency, resulting in excessive noise, increased piping stress, and hidden quality problems. [0003] Among them, during the start-up process of the variable frequency compressor, because the internal moving parts are not fully lubricated in the low frequency range, the frequency is directly increased to the high frequency range, which intensifies the wear of the internal components and shortens the service life of the ...
