Abstract

The invention discloses a compressor oil temperature control method. The compressor oil temperature control method comprises the steps that 1, whether a compressor is in a shutdown state or not is judged, and if yes, the step 2 is conducted; 2, whether the environment temperature T1 is lower than a preset value A or not and whether the temperature T2 of a shell of the compressor is lower than a second preset value B or not are detected, and if both yes, the step 3 is conducted; 3, a coil of the compressor is heated. The invention further discloses a compressor oil temperature control device and the compressor with the same. According to the compressor oil temperature control method, the problem that the oil temperature of the compressor which does not run at low environment temperature is too low can be solved, and the problems of poor lubrication, a restart failure and the like which are caused by the fact that the compressor oil temperature is too low are prevented.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a method for controlling oil temperature of a compressor. The invention also relates to a compressor oil temperature control device. Besides, the present invention also relates to a compressor. Background technique [0002] With the advancement of technology and the improvement of energy efficiency, inverter compressors that are more energy-saving and more convenient to adjust are widely used in air-conditioning, refrigeration and other fields. [0003] In order to reduce the friction of the moving parts of the compressor, a certain amount of lubricating oil needs to be injected into the compressor. This kind of lubricating oil will change its characteristics with the change of temperature. The most significant change is that its viscosity will continue to increase with the decrease of temperature, the lubricating effect will continue to deteriorate, and even a solidification s...
