Air conditioner fluorine deficiency protection control method, air conditioner and computer readable storage medium

Abstract

The invention provides an air conditioner fluorine deficiency protection control method, an air conditioner and a computer readable storage medium. The air conditioner fluorine deficiency protection control method comprises the steps that S1, the air conditioner is started to operate; S2, the air conditioner obtains the exhaust superheat degree SH and the suction superheat degree SSH in real time; S3, the air conditioner judges whether the conditions that the SH is larger than or equal to a value obtained by multiplying beta and a first preset value and the SSH is larger than or equal to a value obtained by multiplying beta and a second preset value are met at the same time or not, if yes, the step S4 is executed, and if not, the air conditioner continues to operate; and S4, the air conditioner detects the outer environment temperature Tw in real time, whether the high-pressure saturation temperature Tc meets the condition that the sum of Tc and K is smaller than or equal to Tw or not is judged, if yes, a compressor is subjected to shutdown protection, and a fluorine-lacking prompting lamp on an air conditioner display lamp panel is turned on for a long time. According to the air conditioner fluorine deficiency protection control method, on one hand, the judgment accuracy of the air conditioner on the fluorine deficiency condition is improved, and the misjudgment condition is avoided; and on the other hand, the effectiveness of the air conditioner fluorine deficiency protection control method is ensured. In addition, the compressor is subjected to shutdown protection after fluorine deficiency is judged, so that damage to parts due to running of the air conditioner in the fluorine deficiency state is avoided, and the running reliability of a unit is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner fluorine deficiency protection control method, an air conditioner, and a computer-readable storage medium. Background technique [0002] Air conditioners are indispensable electrical equipment in people's daily life, and have various structural forms. With the continuous improvement of industrial design level and the application of new technology, new materials, new shapes and new technologies in air conditioners, not only various kinds of air conditioners have been developed, but also the control methods of air conditioners in different environments have also been improved. made corresponding improvements. [0003] Take the fluorine deficiency of multi-connected air-conditioning system as an example. During the long-term operation of multi-connected air-conditioning system, if the system lacks fluorine, the following problems will often exist: [00...

AI Technical Summary

Problems solved by technology

[0007] In view of this, the present invention aims to propose an air conditioner fluorine deficiency protection control method, an air conditioner, and a computer-readable storage medium, so as to solve the problem in the prior art that multi-connected air conditioning systems are prone to misjudgment during the fluorine deficiency protection process , to improve the accuracy of the air conditioning system in judging the lack of fluorine
