Abstract
Provided is a compressor over-load protection control method. The method includes that: the state of a compressor is detected (S101); it is judged whether the compressor is under over-load protection (S102); and when the compressor is under the over-load protection, fluorine shortage protection is shielded (S103). A compressor over-load protection control apparatus includes: a detection unit (10), configured to detect the state of a compressor; a judgement unit (20), configured to judge whether the compressor is under over-load protection; and a shielding unit (30), configured to shield fluorine shortage protection when the compressor is under the over-load protection. Through the method and apparatus, the problem in the relevant art that a fluorine shortage false alarm is easily triggered is solved, thereby achieving the effect of preventing the fluorine shortage false alarm when the compressor is under the over-load protection.
