Provided is a compressor over-load protection control method. The method includes that: the state of a compressor is detected (S); it is judged whether the compressor is under over-load protection (S); and when the compressor is under the over-load protection, fluorine shortage protection is shielded (S). A compressor over-load protection control apparatus includes: a detection unit (), configured to detect the state of a compressor; a judgement unit (), configured to judge whether the compressor is under over-load protection; and a shielding unit (), 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.

Compressor over-load protection control method and apparatus

A method and a system for monitoring an abnormality at an air outlet of a dehumidifier. The method comprises: identifying whether there is a blockage abnormality at the air outlet of the dehumidifier; after a blockage abnormality has been identified, starting a high wind-level operation of the dehumidifier or controlling air deflectors of the dehumidifier to be reset; after the high wind-level operation has run for a set time period or after the air deflectors are reset, identifying whether the blockage abnormality has been eliminated; and after it has been identified that the blockage abnormality has not been eliminated, controlling the dehumidifier to stop running, and sending out a fault cue. The method and system disclosed can avoid influences on the operation, service life and reliability of the dehumidifier due to a long-term blockage at the air outlet of the dehumidifier.
