Abstract

The invention provides a compressor starting method, device and terminal. The method comprises the steps that a compressor is controlled to be started at a first preset frequency, wherein the first preset frequency is smaller than a preset threshold value; parameters including the compressor exhaust gas temperature, the environment temperature, the compressor starting condensing pressure and the running internal machine ratio are obtained; according to the above parameters, the starting manners of the compressor are determined, wherein the starting manners comprise the cold starting manner, the normal starting manner and the quick starting manner; and the compressor is controlled according to the starting manners to rise the frequency until the compressor frequency reaches a target frequent. By means of the compressor starting method, device and terminal, the problem that in the prior art, the inverter compressor is started according to the inherent frequency in the starting process, and consequently the service life of the compressor is shortened is solved, safety starting of the compressor is guaranteed, and the system reliability is improved.

Description

technical field [0001] The invention relates to the technical field of electric appliances, in particular to a method, device and terminal for starting a compressor. Background technique [0002] In the existing methods for starting the inverter air conditioner compressor, the starting method of the compressor is usually within a specified time, given a space voltage vector with a certain amplitude and a certain angle of the compressor rotor, although it can be achieved under the force of a strong pull It starts successfully, but when the compressor is started, such a voltage vector is given to the control chip, which is equivalent to receiving a pulse voltage impact, and long-term operation will definitely shorten the service life of the controller. [0003] In addition, the frequency conversion compressor starts according to the inherent frequency or control method, without considering the situation when the compressor is filled with liquid or lacks fluorine, often because...
