Problems solved by technology

[0002] When the compressor is cold (that is, the temperature inside the compressor is low), the viscosity of the lubricating oil in the compressor will be relatively high, making it difficult to start the compressor. If the compressor is still started at normal temperature, It is likely to cause the compressor to fail to start

Abstract

The present invention provides a compressor startup method and a startup device, wherein, the compressor startup method includes: when receiving a startup command of the compressor, detecting the temperature of the exhaust port of the compressor; Whether the discharge port temperature of the machine is less than or equal to the first predetermined temperature value; when it is determined that the discharge port temperature is greater than the first predetermined temperature value, start the compressor with the normal starting torque corresponding to the compressor and starting the compressor with a starting torque greater than the normal starting torque when it is determined that the discharge port temperature is less than or equal to the first predetermined temperature value. The technical solution of the present invention enables the compressor to be started with a relatively large starting torque when the temperature of the compressor is low and it is difficult to start the compressor, thereby ensuring successful startup of the compressor and improving the success rate of starting the compressor.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a method for starting a compressor and a device for starting a compressor. Background technique [0002] When the compressor is cold (that is, the temperature inside the compressor is low), the viscosity of the lubricating oil in the compressor will be relatively high, making it difficult to start the compressor. If the compressor is still started at normal temperature, It is likely to cause the compressor to fail to start. [0003] Therefore, how to set the starting mode of the compressor according to the hot and cold state of the compressor to improve the success rate of starting the compressor has become a technical problem to be solved urgently. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0005] For this reason, the object of the present invention is t...
