Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0028] figure 1 is a flowchart of a compressor control method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0029] S101, collecting electrical parameters flowing through the compressor;

[0030] S102. Determine whether the compressor is in the state of frequent start-stop according to the electrical parameters, and when it is determined that the compressor is in the state of frequent start-stop, perform protection control on the compressor.

[0031] That is to say, the present invention collects the electrical parameters of the compressor power supply, and judges whether the compressor is in the state of frequent start and stop according to the electrical parameters, and when it is determined that the compre...

Abstract

The invention discloses a compressor control method and device and an air conditioner. Electrical parameters flowing through a compressor are collected, whether the compressor is in a frequent starting and stopping state or not is judged according to the electrical parameters, the compressor is protected and controlled when it is determined that the compressor is in the frequent starting and stopping state, and therefore a user can control the compressor in the running process of the compressor; accordingly, the service life of the compressor is prolonged, the long-term running requirements of a unit are met, and the problem that in the prior art, the compressor cannot be regulated or protected in the working process of the compressor is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a compressor control method, device and air conditioner. Background technique [0002] Existing air conditioners generally have over-current protection measures for the compressor. When the operating current of the air conditioner is greater than the preset value, corresponding measures will be taken to protect the compressor; but for some areas where the power grid is not very stable, when the power supply When the voltage is very low or the voltage fluctuates greatly, there will be unreliability and intermittent pull-in of the electromagnetic switch device that controls the start and stop of the compressor when the air conditioner is started, which will cause the compressor to start and stop frequently in a short period of time. When the compressor starts and stops frequently, since the compressor overcurrent protection value is generally set relatively large, th...
