A kind of air conditioner fluorine deficiency detection method, detection system and air conditioner

Abstract

The invention provides a method for detecting fluorine deficiency in an air conditioner. By detecting the air outlet temperature of the air conditioner in real time, and comparing the air outlet temperature with a corresponding compensation temperature constant, it is judged whether the air conditioner is deficient in fluorine. Compared with the prior art, the present invention has the advantages that: the air conditioner lacking fluorine method can detect the operation effect of the air conditioner in real time only by detecting the air temperature, so as to more accurately judge whether the air conditioner lacks fluorine; and the detection conditions are simple, And suitable for cooling or heating mode, good versatility. The present invention also relates to a detection system to which the above-mentioned method for detecting fluorine deficiency in an air conditioner is applied. In addition, the present invention also relates to an air conditioner to which the above-mentioned detection system is applied.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for detecting fluorine deficiency in an air conditioner, a detection system and an air conditioner. Background technique [0002] As a household appliance for indoor temperature regulation, air conditioners are more and more popular. When the air conditioner lacks fluorine, it will bring about the loss of cooling or heating effect, so that the indoor temperature cannot be lowered or raised, which will affect the user's experience. Poor oil cooling will cause severe wear of compression components and motor bearings, which will cause damage to the compressor. [0003] In order to solve the above technical problems, a method for detecting the lack of fluorine in air conditioners has been proposed at present. For example, at present, the outlet air temperature Tc of the air conditioner is detected, and the detected outlet air temperature Tc is compared with the air...

AI Technical Summary

Problems solved by technology

After the air conditioner lacks fluorine, it will cause the loss of cooling or heating effect, resulting in the problem that the indoor temperature cannot be lowered or raised, which will affect the user experience. At the same time, the lack of fluorine in the air conditioner will cause the compressor motor stator coil and lubrication Poor oil cooling will cause severe wear of compression parts and motor bearings, which will cause damage to the compressor

[0003] In order to solve the above technical problems, a method for detecting the lack of fluorine in the air conditioner is currently proposed. For example, at present, by detecting the air temperature Tc of the air conditioner, the detected air temperature Tc is compared with the current operating mode to set the air temperature Tcm. Judging whether the absolute value of the difference between the two temperatures is greater than or equal to the predetermined value, so as to determine whether there is a problem of refrigerant leakage in the current situation of the air conditioner, and the air conditioner sends a corresponding reminder message of refrigerant shortage. Although this method realizes the detection of fluorine deficiency in the air conditioner, but its The detection needs to set the air outlet temperature, and the judgment of the lack of refrigerant needs to be judged according to the set air outlet temperature, and the judgment result will be affected by the set air outlet temperature, thus affecting the accuracy of the detection
