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. When the power-on detection condition is used, the operation mode of the air conditioner is judged; when the air conditioner is in the first operation mode, it is judged whether the air conditioner meets the preset first fluorine deficiency condition according to the second temperature group and the first temperature group detected by multiple temperature sensors , when the air conditioner meets the preset first fluorine deficiency condition, it enters the fluorine deficiency protection; when the air conditioner is in the second operation mode, the air conditioner is judged according to the third temperature group and the first temperature group detected by multiple temperature sensing packages Whether the preset second fluorine deficiency condition is met, when the air conditioner meets the preset second fluorine deficiency condition, it enters fluorine deficiency protection. The invention also discloses an air conditioner and a storage medium. The invention applies fluorine deficiency protection to both air conditioning refrigeration and air conditioning heating, and reduces misjudgment of fluorine deficiency.

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 ...
