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

Abstract

The invention discloses a fluorine deficiency protection method for an air conditioner. The fluorine deficiency protection method comprises the following steps that whether the air conditioner meets apreset startup detection condition or not is judged according to a first temperature group detected by a plurality of temperature wraps when a compressor is started; when the air conditioner meets the preset startup detection condition, operation modes of the air conditioner are judged; when the air conditioner is in the first operation mode, whether the air conditioner meets a preset first fluorine deficiency condition or not is judged according to a second temperature group and the first temperature group which are detected by the plurality of temperature wraps, and when the air conditionermeets the preset first fluorine deficiency condition, fluorine deficiency protection is carried out; and when the air conditioner is in the second operation mode, whether the air conditioner meets apreset second fluorine deficiency condition or not is judged according to a third temperature group and the first temperature group which are detected by the plurality of temperature wraps, and when the air conditioner meets the preset second fluorine deficiency condition, fluorine deficiency protection is carried out. The invention further discloses the air conditioner and a storage medium. According to the fluorine deficiency protection method for the air conditioner, fluorine deficiency protection is simultaneously applied to air conditioner refrigeration and air conditioner heating, and fluorine deficiency misjudgment is reduced.

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 storage medium. Background technique [0002] With the popularization of air conditioners, air conditioner failures caused by air conditioner refrigerant leakage are gradually increasing. In the field of air conditioners, long-term operation of air conditioners with insufficient refrigerant will cause the compressor to operate at high temperature for a long time, which greatly shortens the use of the compressor. In severe cases, it may even damage the compressor, thereby reducing the performance of the overall air conditioner. Therefore, the fluorine deficiency protection of the air conditioner is very important. [0003] For example, the patent document with the application number 201910218440.7 discloses a detection method for preventing misjudgment of fluorine deficiency. In the ...
