Embodiment Construction

[0037] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0038] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0039] As attached figure 1 As shown, the embodiment of the present invention provides a method for detecting refrigerant failure of an air conditioner, which specifically includes the following steps:

[0040] S1. Prediction of refrigerant failure;

[0041] S2. Refrigerant leakage detection;

[0042] S3. Calculation of refrigerant margin.

[0043] Wherein, when the judgment result of step S1 is that there is no risk of refrigerant failure, the air conditioner is maintained in normal operation, and when the judgment result of step S1 is that there is a risk of refrigerant failure, then step S2 is continued. Through step S2, it can be judged whether the refrigerant of the air condi...

Abstract

The invention provides a method for detecting a refrigerant fault of an air conditioner and the air conditioner thereof. The method for detecting the refrigerant fault of the air conditioner comprisesthe following steps of S1 pre-judging a refrigerant failure, S2 carrying out refrigerant leakage detection and S3 calculating a refrigerant allowance, wherein when the judgment result of the first step is that the air conditioner has the fault risk, the second step is executed, and when the judgment result of the second step is the refrigerant leakage, the third step is executed. According to themethod for detecting the refrigerant fault of the air conditioner, the refrigerant fault can be periodically pre-judged, the refrigerant fault is found in time, multiple parameters such as the temperature of the compressor operation, the temperature of the outdoor unit heat exchanger, the temperature of the indoor unit heat exchanger and the refrigerant density parameter are combined to perform comprehensive detection and judgment of the refrigerant fault, and the detection precision is improved.

Description

Technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for detecting refrigerant failure of an air conditioner and the air conditioner. Background technique [0002] With the improvement of people’s living standards, the penetration rate of air conditioners is getting higher and higher. Faced with the widespread popularity of air conditioners, the maintenance of air conditioners has become correspondingly frequent. Various air conditioner problems on the market are endless. For the air conditioner's refrigerant leakage and other failures, no reasonable solution has been found. [0003] Moreover, once a refrigerant leak occurs, the user can usually only notice the maintenance when the cooling and heating effect of the air conditioner becomes extremely poor. In view of refrigerant leakage, most of the existing technologies adopt more reasonable and sophisticated anti-leakage pipeline valve interfaces and other methods to pl...
