Abstract

The invention provides a method for detecting insufficient refrigerant of an air conditioner and the air conditioner thereof. The method for detecting insufficient refrigerant of the air conditioner includes the following steps: S1. Judging whether the refrigerant filled in the air conditioner is sufficient, if the judgment result is insufficient, perform step S2; S2. Judging the type of refrigerant originally filled in the air conditioner ; S3. Filling the refrigerant circulation pipeline of the air conditioner with refrigerant; wherein, step S1 is regularly executed every other detection cycle. The present invention can compare and judge more accurately and quickly. By querying the pre-stored matrix table, the process of comparing multiple data is simplified, and the accuracy of detection is also improved.

Description

technical field

[0001] The invention relates to the technical field of air conditioners, in particular to a detection method for insufficient refrigerant of an air conditioner and an air conditioner thereof. Background technique

[0002] With the improvement of people's living standards, the popularity of air conditioners is also getting higher and higher. Faced with the large-scale popularization of air conditioners, the maintenance of air conditioners has also become correspondingly frequent. Among them, after long-term use of the air conditioner, there may be a problem of insufficient refrigerant surplus or refrigerant failure caused by pipeline rupture. The problem brought about by the refrigerant failure of the air conditioner is that the temperature adjustment ability of the air conditioner becomes poor, and the user usually finds out the problem and seeks maintenance after the air conditioner runs in the state of refrigerant failure for a long time. At this time, sin...
