Document Type and Number:

WIPO Patent Application WO/2023/226464

Kind Code:

A1

Abstract:

Provided in the present application are an air conditioner dust deposit detection method and apparatus, an air conditioner, and electronic device, the air conditioner dust deposit detection method comprising: acquiring a first temperature value at a first temperature coil and a second temperature value at a second temperature coil; and, on the basis of the absolute value of the difference value of the first temperature value and the second temperature value, determining a dust deposit state of an air conditioner, wherein the first temperature coil is fixed to the upper portion of an air conditioner air inlet, and the second temperature coil is fixed to the lower portion of the air conditioner air inlet. In respect of the air conditioner dust deposit detection method and apparatus, the air conditioner, and the electronic device provided in the present invention, temperatures of crossing tubes of two different heat exchange loops of the air conditioner are respectively collected by means of the first temperature coil and the second temperature coil, and a heat exchange effect of the air conditioner can be determined on the basis of the absolute value of the temperature difference value of the crossing tubes of the two different heat exchange loops, so that a dust deposit condition in the air conditioner can be automatically detected and determined.
