Fluorine deficiency protection method for air conditioner, air conditioner and readable storage medium

Abstract

The invention discloses a fluorine-deficiency protection method for an air conditioner. Whether the ring temperature is within the preset inner ring temperature range and the initial temperature difference is less than or equal to the first preset difference; if so, detect the inner ring temperature and the inner tube temperature in real time and calculate the real-time temperature difference. The difference between the inner tube temperature; when the difference between the real-time temperature difference and the initial temperature difference is less than or equal to the second preset difference and the difference between the real-time detected inner tube temperature and the initial inner tube temperature is less than or equal to the third preset difference When the duration of the first preset duration is reached, the compressor is controlled to stop. The invention also discloses an air conditioner and a readable storage medium. Among them, the temperature difference parameters are judged multiple times to ensure that the air conditioner will not have false protection when there is no fluorine deficiency or a small amount of fluorine deficiency, and reduce the occurrence of false protection.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fluorine deficiency protection method for an air conditioner, an air conditioner and a readable storage medium. Background technique [0002] At present, the refrigerants of air conditioners are mainly fluorine-containing compounds, which are easy to evaporate and liquefy. They absorb heat when evaporating and release heat when liquefied. Air conditioners use this characteristic to transfer energy to achieve cooling and heating. In some cases, the air conditioner will be short of fluorine. The lack of fluorine in the air conditioner not only has poor cooling and heating effects, but also causes the compressor to overheat. In the prior art, the fluorine deficiency protection method of the air conditioner includes a core judgment Parameters, such as power, current, exhaust temperature, etc., but in practical applications, due to the parameter setting deviation of the flu...

[0002] At present, the refrigerants of air conditioners are mainly fluorine-containing compounds, which are easy to evaporate and liquefy. They absorb heat during evaporation and release heat when liquefied. Air conditioners use this characteristic to transfer energy to achieve cooling and heating. In some cases, the air conditioner will be short of fluorine. The lack of fluorine in the air conditioner not only has poor cooling and heating effects, but also causes the compressor to overheat. In the prior art, the fluorine deficiency protection method of the air conditioner includes a core judgment Parameters, such as power, current, exhaust temperature, etc., but in practical applications, due to parameter setting deviations in the fluorine-deficiency protection method, the air conditioner often performs fluorine-deficiency protection without fluorine deficiency, and there are false protections for the air conditioner The situation affects the normal use of the user
