Problems solved by technology

[0002] At present, the common faults of air conditioner indoor units include: poor cooling or heating effect, reduced air volume, temperature sensor drift, and heat exchanger fins are dirty and clogged. The traditional fault detection method for air conditioner indoor units requires disassembly The indoor unit detects each internal component, the detection method is passive and the user experience is poor
In the prior art, when detecting specific faults of the indoor unit of the air conditioner, the indoor unit is often disassembled and screened manually, and the detection efficiency is low

Abstract

The invention provides a fault detection method, a computer readable storage medium, an indoor unit, and an air conditioner. The fault detection method is used for the indoor unit having at least onetemperature sensor and comprises the following steps of: acquiring at least one temperature value determined by the temperature sensor; determining the characteristic quantity corresponding to the heat exchange effect of a heat exchanger in the indoor unit according to the at least one temperature value and the air volume of the indoor unit; and determining the fault state of the indoor unit according to the relationship between the characteristic quantity and the characteristic range. According to the technical solution, the characteristic quantity corresponding to the real-time heat exchangeeffect of the heat exchanger of the indoor unit can be determined through the internal temperature value of the indoor unit obtained by the temperature sensor and the corresponding air volume; the fault state can be quickly and accurately judged; and the detection accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a fault detection method, a computer readable storage medium, an indoor unit and an air conditioner. Background technique [0002] At present, the common faults of air conditioner indoor units include: poor cooling or heating effect, reduced air volume, temperature sensor drift, and heat exchanger fins are dirty and clogged. The traditional fault detection method for air conditioner indoor units requires disassembly The indoor unit detects each internal component, and the detection method is passive and the user experience is poor. In the prior art, when detecting a specific fault of an indoor unit of an air conditioner, the indoor unit is often disassembled and screened manually, and the detection efficiency is low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or relate...
