Abstract

The invention discloses a method and a device for detecting frosting of an air conditioner. Wherein, the method includes: when the air conditioner is in the heating mode, detecting whether the phase current of the outdoor fan DC motor of the air conditioner continues to increase; when detecting that the phase current of the outdoor fan DC motor continues to increase, and the duration of the continuous increase exceeds the first time When the threshold is reached, it is detected whether the temperature of the outdoor pipe of the air conditioner exceeds the temperature threshold; when the temperature of the outdoor pipe exceeds the temperature threshold, it is determined that the condenser of the air conditioner is frosted. The invention solves the technical problem of inaccurate judgment on the degree of frosting in the prior art when the air conditioner is heating.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method and device for detecting frosting of an air conditioner. Background technique [0002] Air conditioners are widely used air-conditioning equipment in people's daily life, which can adjust the temperature and humidity of the air, thereby improving the comfort of people's living environment. During the heating process of the air conditioner, the temperature of the outdoor condenser is low, and when the outdoor temperature is also low, frosting will occur on the outdoor condenser, which will affect the normal use of the air conditioner. Therefore, when the air conditioner works in the heating mode, judging the frosting condition of the outdoor condenser is an important link in the automatic control of the air conditioner. [0003] In the existing judgment of condenser frosting, one is to use fuzzy judgment rules, specifically, after the air conditioner is running in the hea...
