Problems solved by technology

[0002] At present, for air conditioners, when the ambient temperature is low and the humidity is high, the condenser of the outdoor unit is prone to frost. Once frost forms, the heating effect of the air conditioner will be greatly affected, and the heating effect will be greatly reduced. Defrost protection for the air conditioner
Generally, the judging system judges the degree of frosting based on the temperature of the condenser (lower temperature means severe frosting), but in the case of low ambient temperature and low humidity, it is easy to misjudgment, and defrost when there is no frost or slight frosting Frost operation, frequent defrosting, resulting in reduced heating effect and waste of energy consumption

Abstract

The invention provides a defrosting judgment method, a defrosting judgment system and an air conditioner. The defrosting judgment method comprises the steps that in the heating running process of the air conditioner, the rotating speed of a draught fan is detected; if the time when the rotating speed exceeds the rotating threshold value is larger than the first preset time, the change rate of the rotating speed of the draught fan is determined; under the condition that the change rate is not negative, the preset condition of the draught fan is determined; if the continuous time when the running parameter of the draught fan meets the preset condition is larger than the second preset time, the air conditioner is subject to defrosting operation. Through the technical scheme, the defrosting condition in the process that no frost exists or slight frosting happens is avoided, and the heating effect is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a defrosting judging method, a defrosting judging system, a computer device, a computer-readable storage medium and an air conditioner. Background technique [0002] At present, for air conditioners, when the ambient temperature is low and the humidity is high, the condenser of the outdoor unit is prone to frost. Once frost forms, the heating effect of the air conditioner will be greatly affected, and the heating effect will be greatly reduced. Protect the air conditioner from defrosting. Generally, the judging system judges the degree of frosting based on the temperature of the condenser (lower temperature means severe frosting), but in the case of low ambient temperature and low humidity, it is easy to misjudgment, and defrost when there is no frost or slight frosting Frost operation, frequent defrosting, resulting in reduced heating effect and waste of energy consumption.
