Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0027] see figure 1 As shown, according to the first embodiment of the present invention, a method for judging the frosting of an air conditioner is provided, which is mainly used for judging the occurrence of frosting on the condenser of the outdoor unit when the air conditioner is in heating operation, and for judging the frosting of the air conditioner. The method includes the following steps:

[0028] S10: Obtain the chip temperature of the outdoor fan driver chip and the outlet pipe temperature of the outdoor condenser;

[0029] S20: Determine whether the air conditioner needs to defrost according to the chip temperature of the outdoor fan driver chip and the temperature of the outlet pipe of the outdoor condenser;

[0030] If yes, execute step S30: control the air conditioner t...

Abstract

The invention discloses a method and device for judging whether an air conditioner frosts and an air conditioning system. The method for judging whether the air conditioner frosts comprises the following steps that the chip temperature of an outdoor fan driving chip is obtained; whether the chip temperature is larger than a preset temperature value is judged; if so, the air conditioner is controlled to defrost. According to the method and device for judging whether the air conditioner frosts and the air conditioning system, the problem that whether an air conditioner frosts is prone to being wrongly judged in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for judging frosting in an air conditioner, a judging device and an air conditioning system. Background technique [0002] In the prior art, when the air conditioner is in heating operation, frost will form on the condenser of the outdoor unit, that is, the air conditioner will be frosted. In the early stage of frosting, the frost layer is thin, which will not affect the heating effect; but when the frost layer gradually thickens, the heat transfer capacity will decay, which will seriously affect the heating effect. The existing method for judging the frosting of the air conditioner only detects the outlet pipe temperature of the outdoor condenser, and judges whether defrosting is required according to the value of the outer pipe temperature. However, in this judgment method, the temperature of the outer pipe is not only affected by frost, but also affected by ...
