| Zusammenfassung: | The invention relates to the field of electric appliances, and provides a method and device for judging blockage of a filter in an air conditioner. The blocking judgment method comprises the steps of obtaining the actual evaporation temperature of a heat exchanger in the air conditioner; the standard evaporation temperature of a heat exchanger in the air conditioner under the same working condition is obtained, and under the condition that a filter in the air conditioner is not blocked, the evaporation temperature of the heat exchanger is the standard evaporation temperature; and judging whether the filter in the air conditioner is blocked or not according to a comparison result between the standard evaporation temperature and the actual evaporation temperature. According to the blockage judgment method, whether the filter in the air conditioner is blocked or not can be judged according to comparison between the actual evaporation temperature and the standard evaporation temperature under the same working con |
